Big solar heat deal

Big solar heat deal in the Chilean copper sector made possible by two people

Construction will start on three enormous solar industrial heat plants in Chile in the next months. The Chilean power utility Gasco is investing USD 71 million in two flat plate collector fields with a total capacity of 154 MW and will deliver heat for the electrowinning baths to the two …
Energy carriers from solar-powered reactors

Energy carriers from solar-powered reactors

In future, a lot of green hydrogen will be needed in industry as an energy carrier. Currently, this green hydrogen is produced in electrolysers that are dependent on renewable electricity. But green power is also needed for many other applications. Sustainable alternatives to hydrogen production are therefore necessary. This is …
