REMOVING excess CO
2 from the air, producing negative emissions hydrogen, and reversing ocean acidification are the three main goals of clean technology company Planetary Hydrogen. I spoke to founders CEO Mike Kelland and CTO Greg Rau about their plans to use their
electrochemistry process to produce hydrogen while also capturing CO
2 from the air which can then be safely stored in the oceans as a carbonate.
The Earth has a natural cycle to regulate CO
2 on geological timescales. CO
2 is released from sources such as volcanoes, and then eventually is stored in sediments, the ocean, or living organisms. However, humans burning fossil fuels has released excessive amounts of CO
