Humans have an innate desire to name things, but to be honest, we’re not always that good at it. Take climate tech: it’s a category of companies and technologies that, broadly speaking, seek to minimize or reverse our impact on the climate while also helping us adapt to its increasing changes. As terms go, climate

For many industries, lithium batteries just don’t cut it — they’re getting increasingly expensive, require too much space, and sometimes they are just overkill for many industrial use cases. Thermal batteries, on the other hand, can store energy in the form of heat for long periods, are often cheaper to invest in and deploy, and

The Environmental Protection Agency announced today that it will allow California to ban most sales of new gas- and diesel-powered cars and light trucks starting in 2035. California has long been able to set its own emissions standards under the Clean Air Act provided they are more stringent than federal regulations. Under that authority, the

Over the last decade, the Sustainable Ocean Alliance has graduated from dorm room activism to a thousands-strong global network of experts, investors, and “ecopreneurs” — all of whom believe the best way to save the ailing oceans is to embrace innovation. Founder Daniela Fernandez has steered the ship the whole time, and the SOA is

Commonwealth Fusion Systems will build its first commercial-scale power plant just outside of Richmond, Virginia, the company announced Tuesday, with a goal of hooking it up to the grid in the early 2030s. Fusion power has long been derided as being decades away, but the new milestone assumes the possibility of commercial operations within the

Fusion power startup Focused Energy has signed a deal to buy two of the world’s most powerful lasers, the company exclusively told TechCrunch. The massive lasers will be installed in the startup’s future facility, which it is building in the San Francisco Bay Area over the next two years. “These are some of the highest-average-power

Electric vehicle charging startup EVgo is the latest company to secure funds from the U.S. Department of Energy as the Biden administration races to approve clean energy loans before Donald Trump takes over.  Trump has promised to cancel any unspent funds from Biden’s bipartisan Inflation Reduction Act, including the $7,500 tax credit for new EV

AI continues to reshuffle power and energy markets with even oil giants like Exxon Mobil getting into the mix.  Exxon announced this week that it’s planning to build a power plant for data centers, reflecting just how much electricity tech companies expect they’ll need in the coming decade. According to one estimate, nearly half of

G2 Venture Partners, the high-profile firm that spun out of Kleiner Perkins Caufield & Byers, is raising a third fund with a target of $750 million, TechCrunch has learned.  The raise, which was disclosed in a regulatory filing, is a bullish vote of confidence in climate and sustainability startups, while other investors have voiced cautious

The road from scientist to founder is well trodden, but that doesn’t mean it’s easy. Those pitfalls are why, over the last decade, several programs have sprung up to help smooth the path for technical founders. Now, two prominent programs, Activate and The Engine Accelerator, have decided they can give founders an even bigger advantage

Big tech companies spent several months this year touting their investments in nuclear power. Now, the tide is turning to renewables. Google announced on Tuesday that it was funding $20 billion worth of renewable power projects across the U.S. On Wednesday, it was Microsoft’s turn, helping to launch the Climate and Communities Investment Coalition with

SolarSquare has raised $40 million in what is the largest venture round in India’s solar sector. The Mumbai-based startup bootstrapped and was profitable selling to corporate customers for five years before switching to residential solar in 2021. Now it has scaled to powering over 20,000 homes and 200 housing societies across India, and is India’s

Green ammonia startup Amogy has raised $11.2 million of a targeted $90 million round, an SEC filing reveals. The new round’s target is significantly smaller than its last round — a $139 million Series B-1 that was announced in March 2023 — highlighting the challenges that middle-stage climate startups face today when trying to attract

Getting rid of fossil fuels is relatively simple for some things. Housing? Replace furnaces with heat pumps. Cars and light trucks? Ditch internal combustion for batteries and electric motors. Yet for many industries like cement, steelmaking, and more, it’s hard to replace the heating power of fossil fuels. But Dan Stack thinks bricks have a

As data center power demand surges, tech companies are looking for ways to trim electricity use wherever they can. Cooling is an obvious place to start, since it can account for around 40% of a data center’s energy consumption, according to McKinsey. Most data centers are cooled by blowing chilled air through their servers. The

Nuclear power may have received the lion’s share of attention from energy hungry tech companies over the past few months, with Google among them. But it appears that those new reactors won’t be enough for their AI ambitions: Google is now working with partners to build gigawatts of renewable power, battery storage, and grid upgrades

It’s a cruel reality that only about 3% of the world’s water is fresh, and of that, only a fraction is readily available. Yet as the world’s arid regions encounter intensifying droughts, more people are eyeing the other 97% that’s sloshing around in the oceans. Islands, cities, and water districts have been using desalination to

Turning sunflower seeds into sustainable, cocoa-free chocolate has netted Munich-based B2B food tech startup Planet A Foods (formerly QOA) a $30 million Series B funding round. Now, the Y Combinator alum is gearing up for industrialization, with the funds set to be deployed to scale its production capacity by around 7.5x. The round fast follows

Recycling today kind of sucks. People are generally confused about what can be recycled and where. As a result, only about 32% of eligible waste actually gets recycled. It would be a lot easier if people could dump everything into one bin and let the waste management companies deal with it, but that’s proven to

Earlier this year, Meta tried to get its own nuclear powered data center the easy way, by building one next to an existing reactor. But after regulators threw cold water on the plan — the site was reportedly home to a rare bee species — the company is back with a new idea: find a

The globe likely breezed past 1.5°C of warming above pre-industrial levels this year, crashing through the 2016 Paris Agreement’s aspirational target. Further warming increases the risk of catastrophic consequences, including more frequent extreme droughts, floods, and fires; stronger hurricanes; faster-spreading infectious diseases; and declining wildlife and fish populations. A host of carbon-capture startups hope to

Fighting wildfire is a lot like waging war. There are foot soldiers and paratrooper-like smokejumpers, air support from airtankers, and mobile centers that can direct firefighter movements in the field. “It’s a battlefield,” Gadi Benjamini, co-founder and CEO of FireDome, told TechCrunch. “It changes, it’s dynamic, it’s unexpected.” But what firefighters have been missing is

The Department of Energy (DOE) appears to be on a loan-approval spree in the lead-up to President-Elect Donald Trump’s inauguration, and the winners are all companies manufacturing clean energy solutions on U.S. soil. Trump has promised to cancel any unspent federal dollars under President Joe Biden’s Inflation Reduction Act, a bipartisan climate law that allocated

AI’s surging power demand has put several big tech firms at risk of blowing through their climate commitments. But Amazon has partnered with Orbital, an AI startup, to test a new material that removes carbon dioxide from the atmosphere — and they’re using an AWS datacenter as a first site.  One of carbon capture’s biggest

General Motors is selling its stake in the nearly completed Ultium Cells battery cell plant in Lansing, Michigan, to its joint venture partner LG Energy Solution (LGES). GM’s step back from the factory comes amid weakening electric vehicle demand and the potential rollback of Biden administration incentives to produce clean energy domestically.  GM and LGES

President-elect Donald Trump made no secret during his campaigning that he doesn’t think the U.S. should take an aggressive stance on climate change. From leading chants of “drill, baby, drill” to frequently criticizing everything from wind turbines to electric vehicles, he appears poised to cast a shadow over the climate tech sector for the next

Decarbonizing our economies in the race to fight climate change demands a wholesale overhauling of all sorts of production processes to make them as sustainable as possible. Greening chemicals, which are used as ingredients in all sorts of products, is where U.K. startup Deep Blue Biotech is putting its energies. The biotech startup founded in

Battery tech is pivotal as the world leans into electrification to power decarbonization in the race against climate change. But rising demand is putting more attention on the limits and drawbacks of current generation lithium-ion (Li-ion) battery technology. This is where Cambridge University spin-out Molyon hopes to come in: the U.K. startup is developing next-gen

Volkswagen bet big on European-made batteries a few years ago with two massive investments in Northvolt, the Swedish manufacturer. Now the automaker’s €1.4 billion stake is worth less than half that, according to Reuters. The write-downs occurred throughout the current fiscal year as the situation at Northvolt deteriorated.  It’s unclear what Volkswagen’s current stake is

Tesla and Rivian may have resolved a lawsuit in which Tesla accused Rivian of poaching employees and stealing trade secrets. Bloomberg reports that Tesla told a California judge that the companies have reached a “conditional” settlement, and that it expects to seek dismissal of the lawsuit by December 24. Tesla filed the suit, which was
