IMAGE@DLR Sulfuric acid splitting solar reactor The fastest route to commercializing solar hydrogen could be by supplying hydrogen, oxygen and heat for Australia’s copper mining industry with solar thermochemistry, Christian Sattler told this reporter for SolarPACES recently. With his experience heading solar fuels research at Germany’s solar research center at DLR, Sattler sees a synergistic …

IMAGE@C.Forsberg MIT A very large-scale long duration energy storage (LDES) idea from MIT envisages a 1 kilometer-long, 60 meter-wide lidded central storage container of rocks sunk 20 meters down into the ground – about the size of 10 football fields if they were laid end to end. The idea is that it could store energy …

A perovskite may be more cost-effective than ceria for solar-driven thermochemical hydrogen production, a new paper suggests. One perovskite formulation that works at a slightly lower temperature than ceria is explored by Xin Qian in the paper Outstanding Properties and Performance of CaTi0.5Mn0.5O3–d for Solar-Driven Thermochemical Hydrogen Production in research funded by the US Department of …

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 …
