We are Yes VC, comprised of Caterina Fake, Jyri Engeström, Julie Liao and David Pickerell. We fund great companies at the Pre-Seed and Seed stages. Direct Air Capture (DAC) is one the big engineering challenges of the century, and if solved will play a significant part in reversing climate change. The problem, though, is it still costs too much. It requires expensive carbon dioxide-collecting materials known as sorbents, and fans that consume power. Heirloom Carbon has a solution that changes this. Their passive DAC process requires no high-power fans or expensive sorbents. Naturally occurring minerals in rocks—alongside forests, soils, and the ocean—are one of our planet’s most vital carbon sinks, and this process, known as weathering, is what Heirloom has replicated and accelerated for carbon capture. By turning carbon dioxide from air into stone, Heirloom will remove CO2 directly from the air and store it safely and permanently underground, replicating natural processes. Heirloom uses “looping” to reuse mineral inputs dozens of times, and employs renewable energy and electric calcination so no fossil fuels are needed. At scale, it can achieve gigaton-scale carbon dioxide removal at just $50/ton—less than half the cost of powered DAC, and low enough to be a profitable business on the global market, starting with the United States.
