Recycling Waste Water

Heimdal's ocean-based direct-air-capture runs entirely on brine waste water from the desalination process and renewable energy inputs.

Reversing Ocean Acidification

Heimdal uses electrolysis to alkalinize brine waste returning to the ocean, offsetting the effects of ocean acidification and increasing oceanic carbon buffering.

Mineralized Carbon

Heimdal sequesters CO2 as calcium and magnesium carbonates, which form highly stable precipitate sands at the bottom of the seafloor.

Creating Renewable Fuel

The process of extracting acidity from concentrated brine generates Hydrogen gas, a fuel which emits only H2O when burned.

Maximum Impact

Heimdal's highly energy efficient chemical process and rapidly scalable form factor enable impact on a timetable that gives humanity a fighting chance.
