Engineers developing carbon-free hydrogen production system

MIT engineers are developing a carbon-free hydrogen production system driven by solar energy. In a study published in the Solar Energy Journal, the engineers outline a conceptual design for a system that efficiently produces "solar thermochemical hydrogen". The system utilises solar heat to split water and generate hydrogen, an emissions-free fuel suitable for long-distance transportation. Unlike conventional hydrogen production methods that involve fossil fuels, this solar-driven approach relies entirely on renewable energy, providing a cleaner and more sustainable alternative. However, current solar thermochemical hydrogen designs have limited efficiency, with only about 7% of sunlight converted into hydrogen making them low-yield and high-cost. (Environmental News Network)
