Vacuuming CO2 out of the atmosphere may be possible, but at a cost of nearly $1,000 per metric ton of carbon captured and stored. Nevertheless, direct air capture is attracting serious investment from the US government, oil and gas companies and Microsoft. In this episode of Energy Evolution, hosts Taylor Kuykendall and Dan Testa and reporter Siri Hedreen discuss what the public and private sectors are doing to make this nascent technology a large-scale commercial reality.

First, they hear from the Bipartisan Policy Center’s Sasha Mackler on why direct air capture is a worthy investment, and why now. Next, Heirloom Carbon Technologies’ Max Scholten tells S&P Global Commodity Insights what the company is doing to lower the cost of carbon removal. Scholten also explains how clean electricity is a limiting factor, and how Heirloom’s technology design attempts to solve for the intermittency of wind and solar energy.
