Humanising Energy: Removing CO2 from the air

No matter how much we reduce our carbon output, we will be left with 6-10 billion tonnes of unavoidable CO2 emissions. Direct air capture is just one solution that can help remove carbon from the air forever.
About Humanising Energy:
Produced for the World Energy Council by BBC StoryWorks Commercial Productions, "Humanising Energy" is a powerful online series of films and articles displaying the technical innovation taking place across the energy sector through compelling, human-centric stories of creativity, collaboration and community.
With content capturing the stories of remote communities in need of reliable sustainable energy, of innovators changing the future of energy, and of organisations striving to effectively harness the earth’s natural resources, Humanising Energy tells the human story at the heart of the energy sector.

Direct air capture is really a stupid idea. The driving force of 400 ppm CO2 in the atmosphere is so low it takes immense energy to accomplish this. The only sensible capture of CO2 is at the point of generation, i.e. coal and natural gas fired power plants. Here, the driving force is 200,000 ppm. Why wait until it gets diluted in the atmosphere before capturing it? Really dumb. And, I really question if there is enough zero carbon emission energy sources available for carbon capture to make it net negative. There's still the question of what do with it. Mineralization at your small scale may work, but not at the large scales that are actually needed to make a difference. Far better off planting trees and reforestation. But, hey, this all sounds good to the uninformed public and politicians.
