Elon Musk spolu s X-Prize vypsali odmenu 100 mil. USD tomu, kdo jako prvni zachyti 1 t uhliku za den (do roku 2025) s tim, ze se jeho reseni bude dat ekonomicky smysluplne rozsirit na zachycovani 1 Gt uhliku za rok (do roku 2050).

"The world's leading scientists estimate that we may need to remove as much as 6 gigatons of CO2 per year by 2030, and 10 gigatons per year by 2050 to avoid the worst effects of climate change. For humanity to reach the Paris Agreements goal of limiting the Earth’s temperature rise to no more than 1.5˚(C) of pre-industrial levels, or even 2˚(C), we need bold, radical tech innovation and scale up that goes beyond limiting CO2 emissions, but actually removes CO2 already in the air and oceans. If humanity continues on a business-as-usual path, the global average temperature could increase 6˚(C) by the year 2100.
This four-year global competition invites innovators and teams from anywhere on the planet to create and demonstrate solutions that can pull carbon dioxide directly from the atmosphere or oceans ultimately scaling massively to gigaton levels, locking away CO2 permanently in an environmentally benign way.
Solutions will be scientifically evaluated across multiple criteria such as; amount of CO2 removed, life cycle analysis of the removal process, energy efficiency, land footprint and sequestration capabilities.
Any carbon negative solution is eligible: nature-based, direct air capture, oceans, mineralization, or anything else that sequesters CO2 permanently. "
