For three reasons cited in The Fine Article: > The problem is that in the past concentrated solar couldn't get temperatures hot enough to make cement and steel. > While other concentrated solar companies attacked this temperature problem by adding steel to make the technology stiffer and sturdier, Heliogen and its team of scientists and engineers turned to artificial intelligence. > Heliogen said it is generating so much heat that its technology could eventually be used to create clean hydrogen at scale.
