Google’s bets on carbon capture power plants, which have a mixed record

Google said today that it will invest in a natural gas power plant in Illinois that intends to capture the majority of its carbon emissions. The 400-megawatt power plant will be built outside of Decatur next to an ethanol plant run by Archer Daniels Midland (ADM), which already captures CO2 from its operations. Google will […]

How one AI startup is helping rice farmers battle climate change

Fixing climate change is no small task — just ask carbon removal developers like Mitti Labs. The New York-based startup has developed technology to measure how much methane is released by rice paddies and uses it to train hundreds of thousands of farmers in climate-friendly practices. It’s the sort of high-touch endeavor that venture capitalists

Tulum Energy rediscovered a forgotten hydrogen tech and used it to raise $27M

It was a mistake that was ahead of its time. Between 2002 and 2005, engineers with the Techint Group were trying to dial in a new electric arc furnace for a steelmaker when they noticed something odd. The carbon electrodes, rather than breaking down, were growing larger.  The team had inadvertently created what’s known as

Hoofprint Biome boosts cow nutrition while slashing methane burps

Sometimes, answering a long-standing problem is a matter of finding a new perspective. Take methane from cows: For years, people have been trying to eliminate the gas from cow burps in an attempt to limit the livestock’s impact on the climate. But they haven’t made a dent. That’s in part because they were looking at

SpaceX alums find traction on Earth with their Mars-inspired methane-to-CO2 tech

A trend has emerged among a small group of climate tech founders who start with their eyes fixed on space and soon realize their technology would do a lot more good here on Earth. Halen Mattison and Luke Neise fit the bill. Mattison spent time at SpaceX, while Neise worked at Vanderbilt Aerospace Design Laboratory

C-Zero is raising $18M to make emission-free hydrogen using natural gas, filings reveal

Hydrogen startup C-Zero has raised $5 million of an $18 million funding round, according to an SEC filing. The company is developing a way to strip hydrogen from methane without emitting carbon dioxide. The resulting hydrogen can be used in a range of industries today, including ammonia and petrochemical production, and potentially others in the

Exclusive: General Galactic emerges from stealth to make methane from carbon dioxide

Plenty of products benefit from tight integration, where companies design and sometimes build key components of a product in-house: Apple and its custom microprocessors and Tesla and its Superchargers are two notable examples. It’s not an easy strategy to get right, but General Galactic, a stealthy new startup, hopes the approach will let it drive
