Heliogen: concentrated solar breakthrough?

Heliogen has set a new record for concentrated solar power in November 2019, generating >1,000C temperatures from an array of c370 hexagonal mirrors, which are precisely controlled using computer vision. This is almost 2x traditional CSP plants which achieve c560C temperatures.

We have reviewed 21 patents from Heliogen’s predecessor company, eSolar, in order to understand its IP. Not only can it control heliostats more precisely than prior companies, but this allows the heliostats to be down-sized, conferring material cost-savings.

This data-file summarizes the technology, the patents, the costs (in c/kWh and $/mcfe) and the opportunity to decarbonise industrial heat and power generation.
