280 Earth
280 Earth is a climate-tech company that removes carbon dioxide permanently from the ambient air using a modular Direct Air Capture (DAC) system spun out of Alphabet's X, The Moonshot Factory. Its continuous-flow process uses a proprietary sorbent, off-the-shelf industrial equipment and low-grade waste heat or clean electricity to pull CO2 - and fresh water - out of the atmosphere at low energy cost. Its first plant in The Dalles, Oregon began operating in May 2024 and is designed to scale from hundreds to more than 20,000 tons of CO2 removed per year. The company's name references 280 parts per million, the pre-industrial atmospheric CO2 concentration it aims to help restore.
Spiritus
Spiritus is a climate-tech company building passive Direct Air Capture (DAC) systems - stacked trays of sorbent pellets arranged in modular 'Carbon Orchards' - that aim to pull CO2 out of the atmosphere for under $100 per ton, roughly a tenfold cost reduction over conventional DAC.
