Industrial heating is expected to account for a quarter of global CO2 emissions by 2040. Brenmiller Energy is addressing this problem with bGen Zero, a battery that gets its charge from solar or wind energy. That energy then gets converted into heat, which warms up crushed rocks to extremely high temperatures for on-demand, emissions-free steam, hot water, or hot air. This year, Brenmiller opened the world’s first thermal energy storage gigafactory, in its native Israel, where it will scale up production of its bGen modules.
