Various schemes for electrolytically generating H2 while consuming CO2 and transforming it to dissolved mineral bicarbonate.

Limiting global warming to 2 degrees Celsius will require not only reducing emissions of CO2, but also active removal of carbon dioxide from the atmosphere. This conclusion from the Intergovernmental Panel on Climate Change has prompted heightened interest in “negative emissions technologies.” A new study evaluates the potential for recently described methods that capture carbon dioxide from the atmosphere through an “electrogeochemical” process that also generates hydrogen gas for use as fuel and creates by-products that can help counteract ocean acidification.
