Summary
Researchers at the University of Texas at Austin have demonstrated in lab studies that it's possible to generate hydrogen from rocks deep underground while simultaneously sequestering carbon dioxide. The process works for one common rock type, and the team now aims to move to field trials with industry partners. If successful, this approach could provide clean hydrogen for industrial processes that can't be powered by renewable electricity, while also locking away CO2 — and potentially even generating geothermal power as a bonus.
Key quotes
· 2 pulledWe hope to demonstrate that we will be able to generate hydrogen economically while sequestering CO2.
We desperately need clean hydrogen for processes that cannot be powered by renewable electricity – and it might be possible to generate vast quantities from rocks deep underground while locking away carbon dioxide at the same time.
Storing carbon dioxide in rocks while producing hydrogen from them - and perhaps even geothermal power too - could be a double win on the climate front, and several groups are trying to make it happen
