A solar-powered carbon dioxide-trapping device about the size of a two-man tent has secured a $700,000 deal from the world’s tech giants to draw 500 tonnes of carbon from the atmosphere by 2027.
A new Australian company, AspiraDAC , sprang up off the back of the deal, made with global payment company Stripe through its carbon reduction project, Frontier. AspiraDAC said it’s the first solar-powered direct air capture technology project with a commercial partner.
To fulfil the deal, AspiraDAC plans to build about 180 carbon capture modules on an acre of arid land. A bank of DAC devices of that size would, at a cost of at least $1000, remove a tonne of carbon from the atmosphere each day.Artist’s impression of a solar-powered direct air capture machine developed by Southern Green Gas and the University of Sydney.But Frontier only invests in projects it believes could eventually remove carbon at the gigatonne scale for less than U$100 per tonne.
Critics of carbon capture and storage say it allows oil, gas and coal projects a get-out-of-jail free card to continue mining and burning fossil fuels. Many have failed to meet their “It’s very important just to distinguish the fact that it does not involve point source capture of carbon dioxide, that it directly addresses the very critical and urgent need to remove historical emissions of human emissions and carbon dioxide from the atmosphere,” D’Alessandro said.
