The key to plentiful solar power is water, says Massachusetts Institute of Technology Professor Daniel Nocera.
Nocera and his MIT colleague, Matthew Kanan, on Thursday will publish a technical paper that describes what they claim is a breakthrough in solar energy storage.
The idea is to use the energy from solar photovoltaic panels (or another electricity source) to crack water molecules into hydrogen and oxygen gas. Those gases would be stored and used later in a fuel cell to make electricity when the sun is not shining.
The concept is a closed-loop system: running the hydrogen and water through the … Read more
