Heavy industry is responsible for roughly 20% of global carbon emissions, yet there are few low-carbon options for creating the high-temperature heat needed for producing cement and steel. But a new company called Heliogen has developed a brand new, zero-carbon way of generating high-temperature heat.
Based on concentrating solar power (CSP), the technology uses a large number of mirrors in a field that are angled to reflect sunlight onto a tower, which contains a steam turbine. Heat from the sunlight then turns liquid to steam, which runs the turbine, which in turn generates power.
