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 concentrated solar power. MIT engineers aim to produce totally green, carbon-free hydrogen fuel with a new, train-like system of reactors that is driven solely by the sun. In a study appearing today in Solar Energy Journal, the engineers lay out …

100-Gigawatt-Hour Crushed-Rock Heat Storage for Concentrated Solar Power and Nuclear

A very large-scale long duration energy storage (LDES) idea from MIT envisages a 1 kilometer-long, 60 meter-wide lidded central storage container of rocks sunk 20 meters down into the ground – about the size of 10 football fields if they were laid end to end. The idea is that it could store energy from up …
