Aalborg CSP’s steam generation system for the 600 MW DEWA CSP project in Dubai Researchers at DLR, and NREL, and the Bill Gates-funded start-up Malta have been investigating converting coal plants into grid-scale thermal energy storage for curtailed intermittent renewable energy, as low-cost heat “batteries.” Conversion would repurpose most of a coal plant’s assets. Instead …

IMAGE@Alberto de la Calle As a vital component of fertilizers, ammonia (NH3) is the second most-produced industrial chemical in the world. Annual production is around 180 million metric tons and almost 90% of this production goes to meet the global demand for agricultural production. Ammonia is also increasingly seen as a potential green fuel for …
