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. Holmes-Gentle et al.

Taiwan Reboots Its Solar-Power Fishponds

Cars That Think

Taiwan’s government is hoping that the more than 400 square kilometers of fishponds can simultaneously produce a second harvest: solar power. To build it, Taipei-based Hongde Renewable Energy bought 57.6 But nowhere else is the pairing of aquaculture and solar power seen as so crucial to the economy. What is aquavoltaics?

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.

Combining Hydrogen with Renewable Energy: Harnessing Clean Energy and Efficient Storage Solutions

Baua Electric

This makes it a valuable resource for balancing the intermittency of renewable energy sources and for providing a clean energy solution across various sectors. When the electricity used for electrolysis comes from renewable sources like solar or wind power, the hydrogen produced is known as green hydrogen.
