    Yea, and one of the best ways to sequester carbon dioxide is by using algae. Algae biofuels are a great way out of the climate crisis. Use excess energy to produce algae biofuel, net negative emissions.

      But if it’s used as fuel, wouldn’t that typically return the CO2? Just about all fuels are burned, which creates the CO2, and you have to make sure the energy you use to make and transport the fuel is clean, too.

          How does it stay net negative? Carbon goes into the fuel, which is good, but doesn’t like all of it come back out when burned for fuel? My understanding is that these fuels can only really achieve neutrality, and that assumes clean energy used to make the fuel.
