This Gates-backed startup uses super hot bricks to run factories with zero emissions
The bricks are heated with clean energy to over 1,000 degrees Celsius. That heat can then be used in factories that make products like cement, food, plastic.
At a factory making biofuels in California’s Central Valley, the product is sustainable, but the refining process still runs on fossil fuels. Now, the factory just started testing new technology that can eliminate that carbon footprint and cut costs: a giant “heat battery” that stores renewable energy in bricks.
