Check out our previous entry here.

This month’s installment of this column is all AI, though applications for the technology range widely, from two startups that apply AI to trash or recycling, to another that promises to help people breathe and sleep better, to a company that says its AI can help architects and builders spot commercial projects before they’re even announced. Let’s jump in.

$27M to help recycling plants see what’s in trash

For decades, the recycling industry has relied on sampling and educated guesses to understand what moves through its facilities. But wants every discarded bottle, carton and wrapper to become data.

The London-based startup said last month that it has raised a £20.3 million ($27 million) Series B led by technology investor . The company installs AI-powered camera systems above conveyor belts in recycling plants, then uses computer vision to identify materials, products and brands in real time. Greyparrot says that data helps operators recover more valuable materials, improve sorting efficiency and comply with increasingly strict recycling regulations.

Its systems are now deployed in more than 20 countries and have analyzed more than 1 trillion waste objects, per the company. It counts large waste-processing companies such as and among its customers.

The data gathered at plants also feeds Greyparrot’s Deepnest platform, which it says consumer brands including , and use to understand what happens to their packaging after consumers throw it away, helping to inform redesigns and comply with Extended Producer Responsibility rules in places such as Canada and the EU.

The fresh funding will help expand the company’s footprint across North America and Europe and support its goal of preventing more than 1 million tons of waste by 2030.

The raise reflects growing investor interest in applying AI in the physical world rather than behind computer screens. Companies in the physical AI sector raised nearly $47.3 billion in the first half of 2026, Ƶ data shows, up nearly 80% year over year, as startups increasingly apply artificial intelligence to settings such as factories, recycling plants and other 3D environments.

$17M to help robots navigate where GPS can’t

For a recently funded robotics company, the next frontier for physical AI is underground: in mines, tunnels and other places where GPS doesn’t work.

Australian startup said last month that it secured $17 million in new funding. That includes a $10 million equity round backed by , , , and as well as a $7 million venture debt facility from the country’s National Reconstruction Fund Corp. The company plans to scale manufacturing and expand its AI autonomy and cloud mapping platforms.

Emesent is best known for Hovermap, a LiDAR scanning payload that mounts to drones, vehicles or backpacks to create detailed 3D maps of mines, industrial sites and other hazardous environments. But increasingly, the company’s focus is software. Its Cortex AI platform enables robots to navigate autonomously in environments without GPS, while its Aura cloud platform processes and analyzes the resulting spatial data.

The company says its technology is already deployed at more than 200 mine sites worldwide and that it is expanding into the defense, critical infrastructure and construction sectors.

Its raise is another example of increased interest and investment in physical AI. As industries grapple with labor shortages and increasingly dangerous operating environments, startups that combine robotics, computer vision and autonomy are attracting fresh capital to automate work that’s difficult, dirty or unsafe for humans.

Robotics investment funding overall has been on a tear in recent quarters. Startups in the category raised $15 billion globally in 2025 — an annual record that has already been eclipsed partway through 2026 —Ƶ data shows.

$12.25M for AI that treats congestion with sound

We’ve covered AI that can do dirty work like help sort through trash or navigate underground mines. What about AI to help people breathe?

San Francisco-based medtech startup recently raised an oversubscribed $12.25 million Series A led by . The company develops FDA-cleared, noninvasive devices that it says use AI and acoustic resonance therapy to treat congestion and improve sleep without drugs.

The company said its flagship Sonu band personalizes sound waves based on a user’s facial anatomy to open nasal passages, while its newer Spatial Sleep device aims to help users fall asleep faster and stay asleep longer.

The raise comes as investors continue to back AI-powered medical devices that combine software with regulated hardware. Companies that intersect Ƶ’s AI and medical devices industries raised more than $629 million in the first half of this year, our data shows, up about 33% year over year.

$3.85M to turn unrecyclable trash into fuel

Trash and recycling emerged as an unexpected theme in this month’s column. While Greyparrot helps companies better understand what’s in landfills and recycling plants, another recently funded company, , says it’s working to turn unrecyclable garbage into industrial fuel.

The Las Vegas-based company last month announced a $3.85 million round co-led by and to commercialize technology that converts hard-to-recycle plastics and other waste into industrial fuel. The startup says its engineered fuel can replace coal in cement, steel and other heavy industries without requiring factories to modify existing equipment. The new funding will help it build its first commercial U.S. biofuel facility outside Las Vegas.

Global venture investment into cleantech-related startups has been steady but not record-breaking in recent years, Ƶ data shows. Around $15 billion went into rounds for companies in Ƶ’s cleantech-, EV- and sustainability-focused categories in the first half of 2026, putting this year’s funding on track to slightly exceed the 2025 tally, which was the lowest in several years.

$3.5M to predict construction projects before they’re announced

The biggest construction opportunities often surface months before the first request for proposals. promises to use AI to spot them first.

The New York-based startup last month raised $3.5 million in seed funding from ’s accelerator, , and others to build an AI platform for architecture, engineering and construction firms. The startup promises to give such companies an edge over their competitors by helping them discover projects earlier and identify the best path to winning them. Instead of searching public bid databases, Cascade says its tech can analyze signals such as bond filings, property transactions, capital budgets and meeting minutes to identify projects while they’re still taking shape.

Overall funding to real estate-related startups has trended higher in recent quarters, and the sector emerged as a bright spot for seed funding in the first half of 2026, an analysis of Ƶ data shows. Other seed-funded real estate startups this year have spanned areas ranging from streamlining planning and building processes to real estate investing to reducing power consumption in buildings.

Methodology

The Ƶ Ƶ is a curated list that includes private unicorn companies with post-money valuations of $1 billion or more and is based on Ƶ data. New companies are as they reach the $1 billion valuation mark as part of a funding round.

The unicorn board does not reflect internal company valuations — such as those set via a 409a process for employee stock options — as these differ from, and are more likely to be lower than, a priced funding round. We also do not adjust valuations based on investor writedowns, which change quarterly, as different investors will not value the same company consistently within the same quarter.

Funding to unicorn companies includes all private financings to companies that are tagged as unicorns, as well as those that have since graduated to .

Exits analyzed here only include the first time a company exits.

Please note that all funding values are given in U.S. dollars unless otherwise noted. Ƶ converts foreign currencies to U.S. dollars at the prevailing spot rate from the date funding rounds, acquisitions, IPOs and other financial events are reported. Even if those events were added to Ƶ long after the event was announced, foreign currency transactions are converted at the historic spot price.

Battery Storage Startup Antora Closes $550M Series C In One Of Year’s Largest Cleantech Rounds /clean-tech-and-energy/battery-storage-startup-antora-550m-series-c/ Thu, 30 Jul 2026 17:12:19 +0000 /?p=93914 , a company that provides energy through thermal batteries to data centers, announced Thursday that it has raised $550 million in a Series C funding round.

and co-led the financing, which included participation from (/), , , (chairman of ), and others. With the latest round, San Jose, California-based Antora has raised $770 million since its 2017 inception, per Ƶ. It raised $150 million in a Series B round in February of 2024.

The company did not reveal its valuation.

With so much data center demand amid the artificial intelligence explosion, Antora says it will use its new capital to speed up deployment of “large-scale” projects across the country “to meet surging energy demand.”

It recently deployed what it describes as one of the world’s largest battery storage projects, a in South Dakota. The company says its tech is differentiated in that thermal batteries store low-cost electricity as heat in insulated blocks of solid carbon and “deliver it around the clock as heat or power.”

Antora says that the same factory-built modules can serve a chemical plant, a food producer, a steelmaker, a data center, or the grid, without supply- constrained critical minerals or multi-year construction timelines. As a result, it can provide “cheap, clean energy that’s fast to deploy.”

The company also claims that its San Jose, California factory ranks among the country’s largest battery gigafactories.

“From factories to data centers, energy is the bottleneck to industrial growth,” said , co-founder and CEO of Antora, in a release. “Antora has shown we can help break that bottleneck—delivering energy fast, at massive scale, with American innovation.

Despite surging energy demand from AI data centers, cleantech venture investment has been relatively modest in recent years, and Antora’s raise marks one of the sector’s largest this year.

Ƶ shows investors put more than $15 billion into seed- through growth-stage rounds for companies in Ƶ’s cleantech, EV and sustainability-focused categories in the first half of 2026. That puts this year’s funding on pace to slightly exceed the 2025 tally, though that was the lowest total in several years and well below the highs reached in 2021 and 2022.

Schneider Electric’s VC Fund: The AI Buildout Is Creating A New Industrial Investment Cycle /venture/schneider-ai-robotics-energy-qa-chaturvedy-se-ventures/ Mon, 27 Jul 2026 11:00:53 +0000 /?p=93878 This is an ongoing series on investors focused on rebuilding the physical layer. Previous interviews in the series were with ex-Meta CTO Mike Schroepfer, founder of Gigascale Capital, and Peter Barrett, a decade-long investor at Playground Global.

has spent nearly two centuries adapting to successive industrial revolutions — evolving from a 19th century steel and heavy machinery company into a global leader in energy management and automation. Now, through its 1 billion Euro venture fund, , the company is betting that the next transformation will be driven by AI’s collision with the physical world, from data centers and power grids to robotics and industrial automation.

For , who joined SE Ventures in 2022 after leading corporate investments at , AI’s biggest opportunities extend well beyond software. As demand for compute strains energy infrastructure and accelerates reindustrialization, the firm is backing startups building the technologies that underpin the AI economy — investing in everything from data center infrastructure and grid resilience to robotics and industrial AI.

Ƶ News spoke with Chaturvedy about where those opportunities are emerging, why energy has become AI’s defining constraint, and how industrial technology is being reshaped by the AI era. “We were set up with the intent to figure out where the market is headed,” he said.

The significance of the energy and industrial sectors has grown with AI, and that has led even traditionally tech-focused venture investors to rush into the space. “Today, the scarce resource in this entire space is the capacity to build — building, real estate, energy, power and electrification gear,” Chaturvedy said.

SE Ventures , and has notched 12 exits including its most recent, , a 3D metal printing technology acquired by Tokyo-based electronic manufacturer

The firm will often take board seats or board positions and work to bring value to its portfolio companies.

Around 80% of the startups in its portfolio have some level of commercial relationship with a business unit of Schneider Electric. Most often that’s as a partner servicing Schneider’s customers, which is the holy grail, according to Chaturvedy. Sometimes it’s as a vendor, although that remains a smaller set of use cases.

In our conversation, we spoke about power scarcity, the electrical grid, workforce training, reindustrialization and notable portfolio companies.

The interview has been edited for length and clarity.

Gené Teare: Which sectors or investments are you focused on? Where there is a lot of drive or interest because of what is happening in AI?

Chaturvedy: Three things come to mind, especially in terms of the areas we invest in versus the broader construct of the market.

First, AI is getting embedded, and you need to train models, whether open source or proprietary. Model training has upleveled to inference so you need AI infrastructure. is a great example of that.

Five years out, when this CapEx cycle starts to come down and new data centers are perhaps not getting created, data center efficiency will become a hot topic. We are also investors today in a company called , which focuses on that problem. That will come three, five or seven years out. It is going to come. It is not a problem today because we are on the upswing of the CapEx cycle.

Together AI and Hammerhead AI are very interested in partnering with Schneider Electric, because Schneider Electric is a leading electrification player in the data center space. It makes a lot of gear and equipment that go into these data centers. Today, the scarce resource in this entire space is capacity to build: buildings, real estate, energy, power and electrification gear.

The other market impacted by the emergence and growth of AI is the interplay with the grid. There are more demands on the grid beyond the electrification of vehicles, and it is 100x or 1,000x bigger than what we saw with vehicles needing to get charged from inside houses. The grid could not keep up with that capacity in the past, and it certainly cannot keep up with these demands today.

More project developers are coming in and setting up renewables or other types of capacity, but again, the interplay is still with the grid. Anything that helps with grid resilience is clearly an area for us to invest in.

The third thing is the transformative impact of AI on the world of industrials. That is where we are quite excited. Robotics is one clear area where a general-purpose model can allow the same robotics hardware to do multiple different tasks that were not possible in the past, because cognition and inference were not possible at the edge before the advent of large language models.

Companies like in our portfolio —which is one of the most exciting companies at the intersection of robotics and AI — are market-leading indicators of where this world is headed.

There is also an element of using AI to deliver better use cases in the field. Companies like in our portfolio essentially capture warranty data, analyze it and feed results back to design engineers in big corporations. There are a lot of OEMs and hardware companies looking for select use cases where AI can actually be very transformative.

That is what customers are looking for: How can AI be transformative for my business? Whichever startup is working with me in that transformation journey is the startup that will move from POC to adoption overnight. That is essentially the world of successful startups.

Overlaying on top of this is a confluence that we see and watch from our vantage point. When you think about the energy efficiency that needs to happen in these industrial worlds, energy technologies and industrial technologies have to collaborate and deliver those use cases while being energy efficient. That was not the case in the past. Energy was cheaper and more readily available.

Now industrial is taking off. There is more AI adoption. The workforce is getting older, and there is no way to overnight train a workforce in America, so you have to rely on AI. You are going to consume more and more AI for industrial use cases, which was never a business imperative in the past.

This is where the worlds of enterprise and industrial are colliding very quickly in the world of AI.

Increasingly, what I hear is that the bottleneck for AI at this point is energy. Are you seeing some short-term solutions that help with this? What about longer-term technologies?

Chaturvedy: It’s very clear that from a short-term basis — and this isn’t quite an energy-related solution — it’s more about tokens. If you think about the unit economics of an AI data center, it’s the tokens. To generate a token, it costs electricity. To train your model, or infer from a model, you need a lot of tokens. The bigger the model, the bigger the data set, and the more complex the use cases, the more tokens.

Ultimately, it’s a battle of producing tokens cheaply and also consuming fewer tokens through the models that exist today. That’s where optimization is happening, but that’s more in the enterprise space: How can I write clever versions of software that allow me to do essentially that?

The longer-term solution is going to be about — actually, maybe there is a middle layer also — beyond the tokens: When I’m running my data center, can I push inference to a different point in time so I’m not consuming peak electricity rates? Can I manage my HVAC better? You need cooling systems to cool your data center environment, and there are techniques that work really well there. Schneider has also bought some assets in the past.

Then the longer-horizon cycle is really about creating new generation capacity, largely through renewables, hopefully. That’s where I think the whole renewable story, at least in the U.S., becomes very interesting going forward. Related to renewables is storage, which we haven’t touched upon, but BESS — battery energy storage systems — is another space that we look at very closely.

There is a huge discussion in Europe and in America around reindustrialization. How do you see that playing out, given the sectors you’re focused on, industrialization and energy?

Chaturvedy: I don’t think America or Europe really have a choice other than to reindustrialize, given the geopolitical situation and a variety of other factors that I’m sure you fully track as well.

We know that technologically, the U.S. has a competitive advantage. We produce great software engineers, we move fast, and innovation is the lifeblood of U.S. society. There is a lot of innovation happening here, whether it’s robotics, newer models, setting up data centers, energy generation, and so on. That’s where the U.S. is going to lead as we think about reindustrialization: training the workforce, doing things more automatically, with the holy grail being AI startups that result in lights-out manufacturing facilities.

That becomes more of a possibility now. We are never going to be able, in my opinion, in the next three to five years, to replace an aging workforce and expect them to be trained to the same level that a technician with 30 or 50 years of experience was at. But it is now possible that every blue-collar worker with AI in their hands as an assistant becomes a knowledge worker.

Earlier, we used to think about knowledge workers as IT people or white-collar jobs. I think that’s changing. Everybody will be a knowledge worker. AI will be such an equalizer in that sense. There will be different use cases in different environments, but that doesn’t change the business reality. Everybody becomes a knowledge worker.

The second thing to note is that not every job will come back. There is a reality of inflation, cost of living, and the quality of living in America that people are used to, whether it’s base pay, hazardous environments, number of shifts or what have you. As a society, we’ve made certain choices. We’ll be smart about how we leverage more AI and more robotics to get what we want, and not try to emulate other manufacturing-heavy geographies.

But as an economy, as more AI comes, we will move to a different level in terms of what constitutes the GDP of America and the goods and services underneath.

How long do you think that takes to play out?

Chaturvedy: There are certain industries where it’s already happening, data centers being at the forefront. Mainly because the need is very urgent, and there are significant dollars at play today in the data center space, where people are willing to spend the money. In a capitalistic society, everybody is going to chase money. The data center happens to be that today.

But in the next three to 10 years, depending on the CapEx refresh cycle of different industries, we will see more greenfield projects emerge that are natively robotics-oriented and natively industrial automation-oriented, because AI has already caught up.

Right off the bat, every new factory that gets online in the next seven to 10 years will have a basic level of productivity that is way higher than a new factory set up 30, 20 or 15 years ago. The ROI from that factory would be so strong that you would have to expand more capacity there. And by the way, capacity would also be more scalable.

On reimagining or thinking through the data center stack: is there anything you want to say about that as we close out?

Chaturvedy: We specifically invest in AI for energy and industry, looking across the full stack from data infrastructure to training and inference, through to AI agents solving real-world use cases. We also consider the enabling layers around that stack, like multi-cloud, multi-LLM, cybersecurity, and data governance.

Ultimately, every industry is going to build its own version of this stack, and we believe the most compelling companies will be the ones who drive tangible outcomes in enterprise and industrial environments.

Europe Posted Its Strongest Venture Funding Quarter In 4 Years As UK Gains, M&A Holds Up /venture/data-funding-ai-ma-up-europe-q2-2026/ Thu, 09 Jul 2026 11:00:22 +0000 /?p=93808 In Q2, Europe posted its strongest quarter in four years for venture funding, Ƶ data shows. All told, Europe-based startups raised $24 billion in the just-ended quarter, up around a third quarter over quarter and two-thirds higher than the $14.4 billion raised in Q2 2025.

Within the region, U.K. startups gained significant share in Q2, raising more than $10 billion. That marked the third-largest funding quarter for the U.K. on record, and came in at less than $500 million below its peak quarter in 2021.

Ƶ startup M&A activity also picked up in Q1 and continued that momentum in Q2, even as public-market exits stayed subdued.

Table of contents

Large rounds drive gains

Four companies raised venture fundings of a billion dollars or more last quarter, accounting for 25% of all startup investment in the region in Q2, Ƶ data shows.

Those billion-dollar-plus rounds were raised by an AI-centric group: -owned AI drug developer , which was spun out of ; green steel production manufacturer ; , which is developing robots for home and industrial applications; and , an AI lab founded by former DeepMind researchers.

However, most of the growth in funding year over year and quarter over quarter was driven by rounds of $100 million and over. The majority of funding — 65% —went to a group of 42 companies that raised rounds of $100 million-plus. Sectors that stood out for these companies include biotech, quantum, financial services, AI labs, aerospace, semiconductor, robotics and energy.

H1 2026 up 50%

Funding to Europe-based startups in H1 was up 50% year over year to total $42 billion, Ƶ data shows. Still, the region’s startup investment for the first half of the year remained well below the 2021 H1 peak, when VC funding in Europe totaled $60 billion.

It’s also drastically lower than the $392 billion raised in North America’s record-setting H1, with that region’s funding up 158% year over year.

Europe’s funding deal count subsided last quarter, but mostly at the seed stage. Late-stage rounds were up a bit, while early-stage deals dipped slightly year over year. (It’s worth noting, seed stage rounds are often added to the Ƶ data set after the close of the quarter, so those numbers will increase over time.)

UK momentum builds

The United Kingdom widened its venture-funding lead last quarter, as startups based in the country raised $10.4 billion — not far from the peak in 2021 at $10.8 billion.

The region’s No. 2 startup market, Germany, trailed with $3.2 billion raised by its startups in Q2, and France followed in third place with $2.4 billion. Sweden was Europe’s fourth-largest startup market last quarter, with its companies raising $2 billion.

Ƶ data shows funding to Europe’s AI-focused companies reached more than $10 billion in Q2 — the largest quarterly amount so far — but slightly below the Q1 percentage, when those companies raised more than half of the region’s startup investment.

By stage

Europe’s late-stage funding totaled $12.1 billion in Q2, up 90% year over year. Large Series C and D rounds were raised by Germany-based robotics developer Neura Robotics; Netherlands-based , which makes inspection tools for semiconductor manufacturing; U.K.-based quantum computing startup ; and Germany-based satellite launcher .

Early-stage funding reached $8.6 billion across 250-plus Europe-based startups last quarter, Ƶ data shows. Large Series A and Series B rounds were raised by London-based Isomorphic Labs, London-based AI self-learning lab , Germany-based fusion energy company , London-based semiconductor developer , and London-based quantum processor provider .

Ƶ seed funding totaled $3.2 billion last quarter, with a billion dollars of that raised by just one company: Ineffable Intelligence.

Other large seed rounds were raised by , a London-based AI lab for science; Italy-based autonomous driving technology producer ; and Stockholm-based defense tech company .

M&A increase

While IPO activity for Ƶ startups was muted, M&A showed strong momentum following increased activity in Q1. A total of 154 Europe-based, venture-backed companies were acquired for a cumulative $11.5 billion or more in Q2, Ƶ data shows. That includes three companies acquired for more than $1 billion each in biotech, industrial AI and micromobility.

Looking ahead

Ƶ startup investment has now steadily increased since the fourth quarter of 2024, with increased momentum in the just-ended quarter, driven by larger rounds of $100 million and over. The region’s startup ecosystem shows particular strength in deep tech and financial services as well as the formation of new AI labs, and M&A activity has fueled liquidity for the next batch of startups.

Now the question remains: Will it be enough to keep Europe competitive with the frontrunners, the U.S. and China?

Methodology

The data contained in this report comes directly from Ƶ, and is based on reported data. Data is as of July 6, 2026.

Note that data lags are most pronounced at the earliest stages of venture activity, with seed funding amounts increasing significantly after the end of a quarter/year.

Please note that all funding values are given in U.S. dollars unless otherwise noted. Ƶ converts foreign currencies to U.S. dollars at the prevailing spot rate from the date funding rounds, acquisitions, IPOs and other financial events are reported. Even if those events were added to Ƶ long after the event was announced, foreign currency transactions are converted at the historic spot price.

Glossary of funding terms

Seed and angel consists of seed, pre-seed and angel rounds. Ƶ also includes venture rounds of unknown series, equity crowdfunding and convertible notes at $3 million (USD or as-converted USD equivalent) or less.

Early-stage consists of Series A and Series B rounds, as well as other round types. Ƶ includes venture rounds of unknown series, corporate venture and other rounds above $3 million, and those less than or equal to $15 million.

Late-stage consists of Series C, Series D, Series E and later-lettered venture rounds following the “Series [Letter]” naming convention. Also included are venture rounds of unknown series, corporate venture and other rounds above $15 million. Corporate rounds are only included if a company has raised an equity funding at seed through a venture series funding round.

Technology growth is a private-equity round raised by a company that has previously raised a “venture” round. (So basically, any round from the previously defined stages.)

Sector Snapshot: Cleantech Startup Funding Stabilizes As Energy Demand Grows /venture/startup-funding-clean-energy-exits-ipo-q2-2026/ Mon, 06 Jul 2026 11:00:35 +0000 /?p=93792 Cleantech isn’t the hottest space for startup funding these days. That title obviously goes to AI.

Nonetheless, amid a period of soaring , rising EV adoption rates, and accelerating progress in fusion and other fields, cleantech investment activity isn’t slowing down.

In the first half of this year, investors poured $15 billion into seed- through growth-stage rounds for companies in Ƶ cleantech, EV and sustainability-focused categories. That puts funding on track to slightly exceed the 2025 tally, which was the lowest in several years.

On a quarterly basis, funding is also on the rise. Around $8 billion went to companies in cleantech and related categories in the second quarter of this year, the highest quarterly total since 2024.

Even taking into account recent gains, however, cleantech funding remains far below its former peak in 2021 and 2022. Given that overall venture funding has risen with the AI boom, cleantech also accounts for a smaller share of total investment.

Where funding is concentrating

That’s not to say megarounds aren’t getting done in the sector. A look at the largest funding rounds of 2026 paints a varied picture of where capital is concentrating.

Stockholm-based green steel producer scored the largest financing of 2026, securing $1.6 billion in a round led by Swedish asset manager . Stegra plans to use the money to complete the construction of its large-scale steel plant.

The next-biggest round went to , a -backed startup that has been generating buzz and reservations for a flagship electric pickup starting at around $25,000 that can be converted to an SUV. Troy, Michigan-based Slate raised $650 million in Series C funding in April and plans to deliver its first trucks to customers later this year.

The third- and fourth-largest financings were fusion deals. The latest of those went to , which raised $465 million in a June Series G funding to go toward building a fusion power plant. The -led round set a $15.5 billion post-money valuation for the Everett, Washington-based company.

A few months earlier, fusion startup picked up $450 million in Series A funding led by . The San Francisco-based company, formed around a fusion breakthrough at , plans to build the world’s most powerful laser to further its goal of grid-scale energy production.

For a broader view of where large financings are concentrating, below we put together a list of 10 of the largest cleantech-related rounds this year.

Under the circumstances, the space looks underfunded

While sums going to cleantech-related startups aren’t tiny, looking at total investment tallies does leave one with the impression that the space looks underfunded.

After all, energy is a growth sector, and clean energy is leading the way. The forecasts the share of renewables and nuclear in the world’s power mix will rise to 50% by the end of this decade. At the same time, global power demand is set to grow by more than 3.5% per year on average over the rest of this decade.

Exits of venture-backed companies are also happening, another source of encouragement for startup investors. The most recent IPO in the space was geothermal provider , which went public in May, raising $1.9 billion. The Houston-based company had a recent market cap around $8.6 billion.

On the nuclear power front, , a developer of small modular reactors, carried out its own Nasdaq IPO in April, raising $1 billion. The Rockville, Maryland, company was recently valued at a little over $5 billion.

Looking ahead, it’s not far-fetched to see myriad factors that could power clean energy, sustainability and EV sectors higher. For clean power in particular, the voracious energy demands of AI are certainly a catalyst to consider. We’ll stay tuned to see if growing energy demand ultimately translates into greater startup investment.
