EPFL solar hydrogen system co-generates heat and oxygen

Green Car Congress

EPFL researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its size. This is the first system-level demonstration of solar hydrogen generation. Resources Holmes-Gentle, I., Holmes-Gentle et al. Tembhurne, S.,

Rice U team creates low-cost, high-efficiency integrated device for solar-driven water splitting; solar leaf

Green Car Congress

The platform developed by the Brown School of Engineering lab of Rice materials scientist Jun Lou integrates catalytic electrodes and perovskite solar cells that, when triggered by sunlight, produce electricity. The concept is broadly similar to an artificial leaf. Illustration by Jia Liang. —Jia Liang. and Ruth L.

Caltech’s SSPD-1 Is a New Idea for Space-Based Solar

Cars That Think

Several recently published deep-dive analyses commissioned by NASA and the European Space Agency have thrown cold water on the hope that space solar power could affordably generate many gigawatts of clean energy in the near future. Ali Hajimiri is the codirector of Caltech’s space-based solar power project. And yet the dream lives on.

Convert Oil Wells to Solve the Solar Storage Problem

Cars That Think

One of the main impediments to harnessing solar energy is storage. Solar batteries work as a short-term solution, but not when it comes to long-term storage or to power, say, an entire city. Solar energy and oil wells might sound like an odd combination, but the principle is similar to how geothermal energy would be harnessed.
