Israeli research: Microalgae produce green hydrogen without harming the nutritional value of biomass

Researchers from Tel Aviv University and Ben-Gurion University have shown that green hydrogen can be produced from microalgae continuously and on a larger scale, while maintaining the biomass as a high-quality raw material for food, feed, and nutritional supplements.
