Concentrated solar heat and hydrogen to decarbonize iron ore processing

Steel production accounts for roughly 7% of global greenhouse gas emissions, and nearly 70% of that comes from coal-fired blast furnaces; the dominant way the world has made iron for centuries. The Electric Arc Furnace (EAF) could decarbonize steelmaking because it can be powered by renewable electricity. It requires very pure sponge iron. Porous sponge …

Published at Renewable Energy – Design and performance optimization of dual-tower and triple-tower heliostat fields

Abstract: As solar tower systems continue to develop towards larger scales, it is necessary to configure dual-tower and triple-tower fields with higher heat collection capacities. This paper designs and optimizes the performance of dual-tower and triple-tower heliostat fields. Two field arrangement strategies are employed to alter the distance between towers and results show that the …
