Heirloom Carbon raises $150M to remove CO2 from the air using rocks

The globe likely breezed past 1.5 degrees 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 […]

Amazon teams up with Orbital to remove CO2 from the air at one of its datacenters 

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

Microsoft bets a carbon removal bake-off will help offset its skyrocketing AI emissions

Microsoft is in a pickle: It has committed to being carbon negative by 2030, but its emissions have skyrocketed more than 40% since 2020, thanks in part to its booming AI business. The company has bought a bunch of renewable power, but some emissions, like air travel, have been impossible to eliminate. What’s a Big

Aerleum plans to turn CO2 directly into fuel for cargo ships and, eventually, airplanes

It only took four phone calls for Sébastien Fiedorow to quit his job as a venture capitalist. The first one came from Marble, a startup studio based in Paris. They had a scientist looking for help founding a company that would remove carbon dioxide directly from the atmosphere — what experts call direct air capture, or

Direct ocean capture may be the next frontier for carbon removal

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

Phlair’s carbon sucking technology could lower direct air capture’s costs

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

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
