Cooking up concrete solutions to cement’s carbon problem

On the edge of a nondescript industrial park in Lancaster, at the site of an abandoned driving range, glimpses of a 55-foot tower outfitted with black pipes and cameras, and which sometimes glows with the light of many suns, suggest something out of the ordinary is happening behind the property’s gates.

Here, Pasadena-based startup Heliogen is perfecting its version of a concentrated solar power plant. A field of mirrors have been programmed to follow the sun and beam light up to a tower-top receiver, which is linked to a system that can capture and store intense heat.
