44.01 is fighting climate change by eliminating CO2 using the natural power of mineralisation! Their process involves taking captured CO2 underground, speeding up its reaction with peridotite, a rock which naturally mineralises CO2 and permanently removing the CO2 for thousands of years. The company acts as a service provider to carbon capture companies providing them a solution to permanently remove their captured CO2 from the planet. 44.01's process is solely powered by clean energy and utilises solar thermal and PV during the day and biofuels at night. 44.01's technology unlocks an impactful capacity of permanent CO2 storage needed for the world to reduce levels of CO2 in our atmosphere permanently.
