Improved “Solar Thermochemical” process captures 40% of the sun’s heat to produce Green Hydrogen

MIT design would harness 40 percent of the sun’s heat to produce clean hydrogen fuel. Conventional systems for producing hydrogen depend on fossil fuels, but the new system uses only solar energy. By Jennifer Chu, MIT News.

Solar Thermochemical Hydrogen

$1 per kg by 2030

Very different from Hydrogen made from electrolysis

Reversible rusting process

Rust and rails

From 7% to 40% efficiency
