Carbon neutral fuels firm Prometheus Fuels, headquarted in California, has made claims its new technology can deliver direct air capture (DAC) dramatically more cheaply than other technologies, quoting a figure of under $50 per tonne.
Its system captures carbon dioxide directly from ambient air and combines it into water and feeds it into its Faraday Reactor, bypassing traditional gas purification, compression, absorption and desorption, and the associated costly infrastructure.
Rob McGinnis, founder and CEO, said the development marked “a whole new business model” rather than an incremental improvement.
“When you combine ultra-low-cost DAC with modular, off-grid electrochemical fuel production, you open up access to remote, off-grid solar – the cheapest source of energy on the planet – making it available anywhere in the world as a new low-cost source of 24/7, firm, dispatchable, carbon neutral power,” he said.
