At Planetary Hydrogen, we’re working on that future.   We produce the greenest hydrogen on Earth which, when combined with biofuels, enables the production of drop in carbon negative fuels.

Technology

 The patented Planetary Hydrogen Ocean Air Capture (OAC) technology uses renewable electricity to produce hydrogen via conventional electrolysis of water. We call our process SeaOH2. Our innovation is that by adding a mineral salt, we force the electrolysis cell to also create an atmosphere-scrubbing compound called mineral hydroxide as a waste product. That hydroxide actively binds with carbon dioxide, producing an “ocean antacid” very similar to baking soda.   The net effect is the direct air capture and storage of CO2 while producing valuable pure hydrogen. The system can consume as much as 40kg of CO2 and permanently stores it for every 1kg of hydrogen it produces.   This system accelerates “The Earth’s Natural Thermostat” which is the geological process that removes excess CO2 from the atmosphere via rock weathering that is otherwise very slow and inefficient. Excess CO2 in the atmosphere acidifies rainwater that on contact with alkaline minerals (exposed on much of the Earth’s land surface), dissolves the rock and consumes CO2, forming dissolved mineral bicarbonate which is washed into the ocean.  This process is the reason that some 90% of the Earth’s surface carbon is in this form as seawater bicarbonate. While effective as a moderator of excess atmospheric CO2, it can take 100,000 yrs for the preceding process to naturally return atmospheric CO2 to “normal” levels.
