The hottest new climate technology is bricks

Heat batteries could help cut emissions by providing new routes to use solar and wind power.

A handful of startups think bricks that hold heat could be the key to bringing renewable energy to some of the world’s biggest polluters.

Industries that make products ranging from steel to baby food require a lot of heat—most of which is currently generated by burning fossil fuels like natural gas. Heavy industry makes up about a quarter of worldwide emissions, and alternative power sources that produce fewer greenhouse gases (like wind and solar) can’t consistently generate the heat that factories need to manufacture their wares.
