Over the last several years, fusion power has gone from the butt of jokes — always a decade away! — to an increasingly tangible and tantalizing technology that has drawn investors off the sidelines. The technology may be challenging to master and expensive to build today, but fusion promises to harness the nuclear reaction that

Nearly every founder has the same concern: how can they ensure their startup has enough cash to deliver on its promise. For most, that means wooing venture capitalists early and often, trading equity in the company and board seats for cash to keep the lights on. For Teague Egan, it also means courting retail investors.

During COVID-19, Wiley Webb embarked on a year-long trip with his wife to try to figure out the most pressing issues in the food system. He talked to people at more than 70 farms and consistently heard that they wanted more buyers. Large buyers told Webb they wanted to find these farm suppliers but couldn’t

The offices of plant-based protein startup Heura are tucked away down a narrow street a short distance from one of Barcelona’s main tourist draws. But the team of entrepreneurs and food scientists won’t be remixing their protein cocktails in close proximity to La Sagrada Família for much longer — they’re moving to new, larger digs

For the past few years, direct air capture has been seen as a potential silver bullet to the climate crisis. But now a startup originally from the snowy wastes of Iceland is taking a new approach: removing carbon from seawater.  The industry standard for removing carbon with direct air capture methods costs anywhere between $230

Fusion startups have been on a fundraising tear lately, and a young startup, Acceleron Fusion, is joining the pack, having raised $15 million of a targeted $23.7 million round, according to an SEC filing. The fusion sector recently has been showered with interest from investors, who no doubt have been encouraged by the breakthrough experiment

The race for commercial fusion power is heating up. Investors have poured money into fusion startups over the last several years, and one of the more recent beneficiaries of their beneficence is Zap Energy, an Everett, Washington-based startup that’s pursuing a clever approach to harnessing the power of the stars. The company recently closed a

Funding for green hydrogen startups — particularly at the growth stage — has dipped. Hydrogen plants and fueling stations across the U.S. have shut down. And automakers and governments seem to be on the battery electric vehicle (BEV) buzz. And yet, BMW recently announced plans to work with Toyota to develop a hydrogen fuel-cell consumer

When it comes to fusion power, there are two basic approaches: One, create a small star here on Earth that’s held in place by powerful magnetic fields. Two, use intense lasers to make a succession of even smaller stars, but repeat the process several times per second. Moritz von der Linden likes his odds with

As a fuel, hydrogen has a lot going for it. You can burn it for heat to replace coal, you can run it through an electrolyzer to generate electricity, and you can use it to refuel a vehicle as quickly as gasoline or diesel. But it’s challenging to get hydrogen to where it’s needed. As

Toyota Ventures started in 2017 to help startups figure out what the future will look like, with an eye towards ensuring Toyota as an automaker and brand would stay at the forefront of innovation.  While the firm initially targeted mobility startups, the crossover into climate tech was a natural progression. Today, Toyota Ventures has over

When is raising $14 billion not enough? When you’re a battery startup. Northvolt, Europe’s attempt at building a competitor to Asia’s battery manufacturing powerhouses, announced on Monday that it had halted work on a factory expansion and laid off 1,600 employees, or about 20% of the workforce. The company was planning to expand its Ett

Rivian has revealed the first $10 million worth of grants from the Rivian Foundation, three years after the EV maker vowed the philanthropy would receive 1% of its equity to make the “natural world” a “stakeholder in our success.” Rivian Foundation launched Monday a website that details 41 grantees who will collectively receive just north

Jim Adler, founder and general partner at Toyota Ventures, is concerned that climate technology gains could fall into the “valley of death” if companies fail to drum up enough demand to survive.  And he’s not wrong to be worried.  Climate tech investments in the first half of 2024 dipped for the second consecutive year, both

Microsoft made waves last week when it announced a deal with Constellation Energy to restart a nuclear reactor at Three Mile Island to meet its surging data center power needs, bucking the power source’s seemingly terminal decline. In the last decade, seven nuclear reactors have been decommissioned in the U.S., while only two new ones

After taking on water during the pandemic, Zin Boats is back with a bigger, better electric watercraft that it has built from the hull up — again. And with the first craft off the line going to none other than Bill Gates, the company’s plan to power a new generation of clean, high-tech boats has

James McGinniss has been obsessed with decarbonization and the energy grid since he was a high schooler over a decade ago. Now, his startup David Energy has a lofty goal: getting the energy grid to run entirely on clean energy in the next 10 years. Brooklyn-based David Energy is a software-enabled retail energy provider. It

A hopeful entrant in the emerging market of electric watercraft is out of action and being sold for parts. Pure Watercraft was founded in 2011 with the intention of replacing gas-based outboard motors with fully electric ones. We covered the company in 2016 when it began taking preorders for its first commercial outboards, and in

The federal government is handing out another $3 billion to startups in the buzzy battery tech sector.  The investment, which the Biden administration announced Friday, is the latest injection of capital to come from a $16 billion pot that the Department of Energy set aside to build out local battery manufacturing, processing, and recycling facilities.

The data centers that train all the large language models behind AI consume unimaginable amounts of energy, and the stakes are high for big tech companies to ensure they have enough power to run those plants. That’s why Microsoft is now throwing its weight behind nuclear power. The tech giant on Friday signed a major

The use of 3D printing has been praised as an alternative to traditional construction. It promises to deliver faster construction times, creative design, and fewer construction errors, all while reducing carbon footprints. New research out of MIT points to a compelling new take on the concept, relying on 3D-printed glass blocks shaped like a figure

Launching a new product is challenging, but doing it in a space dominated by tech giants requires bold innovation, sharp strategy, and the ability to scale quickly. TechCrunch Disrupt 2024 — taking place at Moscone West in San Francisco from October 28-30 — brings together three experts who are doing just that, while simultaneously addressing

Last year, the U.S. designated magnesium as a critical mineral, one of the “electric 18” that are critical for the energy transition. The metal is used in a range of electronics, and it weighs less than aluminum, making it an attractive alternative for automakers.  But like with so many other minerals, China has grown to

When it comes to climate change, there’s no such thing as a “get out of jail free” card. But there might be an inexpensive alternative: direct air capture. The technology isn’t exactly an exoneration, but more like community service; it promises to suck massive amounts of carbon dioxide out of the atmosphere, atoning for our

Al Gore has enjoyed a very successful career, including as a U.S. senator, U.S. Vice President, U.S. presidential nominee, and even Nobel Peace Prize winner in 2007 for “informing the world of the dangers posed by climate change.” This past May, he was awarded the Presidential Medal of Freedom for his lifetime of service. What

Hydrogen might be touted as a fuel of the future that stands ready to decarbonize shipping and industry, but for the 90 million metric tons used today in everything from fertilizer production and chemical manufacturing, 96% is derived directly from natural gas, oil, or coal. For instance, one of the most common ways is through

Accounting for the emissions of a global tech empire is not a simple task, and what industry standards we do have for disclosure may allow tech companies to systematically understate their carbon footprint. A Guardian report compares official declarations of carbon emissions, including what amount to offsets purchased elsewhere, with “location-based” emissions, another standard metric

Next year, even wildfires won’t be able to hide from Google. The company is working with Muon Space, the Earth Fire Alliance, and others to launch FireSat, a constellation of satellites that will monitor Earth’s surface for wildfires, updating imagery for authorities every 20 minutes. Google helped develop the infrared sensors that’ll look for telltale

Over the last several years, fusion power has gone from the butt of jokes — always a decade away! — to an increasingly tangible and tantalizing technology that has drawn investors off the sidelines. The technology may be challenging to master and expensive to build today, but fusion promises to harness the nuclear reaction that

What could be more frightening than Friday the 13th? How about a realization that AI is in its awkward tween stage? At least, it was for the TC Equity pod crew, which this week included hosts Devin Coldewey and Kirsten Korosec along with TC reporters Tim de Chant and Dominic Madori Davis. AI is often
