NREL scientists advance solar thermochemical hydrogen (STCH) production

Green Car Congress

The NREL scientists analyzed solar thermochemical hydrogen (STCH) production, which can be potentially more energy-efficient than producing hydrogen via the commonly used electrolysis method. Electrolysis needs electricity to split water into hydrogen and oxygen. A conceptual solar thermochemical hydrogen production platform.

Tesla submerges Powerwall 3 in water amidst larger advertising efforts

Teslarati

In a brief advertisement video shared on YouTube earlier this month, Tesla showed a demonstration of the recently released Powerwall 3 submerged in water and still powering appliances, noting that it can continue to operate in more than two feet of water. The Powerwall 3 offers an energy capacity of 13.5 kWh and 11.5
