Heimdal pulls CO2 and cement-making materials out of seawater using renewable energy

One of the consequences of rising CO2 levels in our atmosphere is that levels also rise proportionately in the ocean, harming wildlife and changing ecosystems. Heimdal is a startup working to pull that CO2 back out at scale using renewable energy and producing carbon-negative industrial materials, including limestone for making concrete, in the process, and […]

44.01 secures $5M to turn billions of tons of carbon dioxide to stone

Reducing global greenhouse gas emissions is an important goal, but another challenge awaits: lowering the levels of CO2 and other substances already in the atmosphere. One promising approach turns the gas into an ordinary mineral through entirely natural processes; 44.01 hopes to perform this process at scale using vast deposits of precursor materials and a […]

Holy Grail raises $2.7M seed fund to create modular carbon capture devices

The founders of Holy Grail, a two-year-old startup based in Mountain View, California, are taking a micro approach to solving the outsized problem of capturing carbon. The startup is prototyping a direct air carbon capture device that is modular and small — a departure from the dozens of projects in the U.S. and abroad that […]
