Carbon Engineering vs Spiritus

Carbon Engineering was a pioneering Canadian direct-air-capture company founded by physicist David Keith; it was fully acquired by Occidental Petroleum for about $1.1 billion in 2023 and folded into Oxy Low Carbon Ventures.

Spiritus is a Los Alamos spinout pursuing passive, low-energy direct air capture using a lung-like sorbent arranged in a 'Carbon Orchard.'
