Massachusetts Institute of Technology (MIT) scientists have developed a train-like concentrated solar power (CSP) system for hydrogen production, with plans to build a prototype in the coming year. They say that this innovative system can capture up to 40% of the sun’s heat to produce environmentally friendly hydrogen fuel.
MIT researchers have developed a new CSP system to produce green hydrogen. The system, which is currently in the conceptual stage, aims to use up to 40% of solar heat for green fuel generation – a significant improvement from previous systems, which only achieved a 7% utilization rate.
“The increase in efficiency could drive down the system’s overall cost, making solar thermochemical hydrogen (STCH) a potentially scalable, affordable option to help decarbonize the transportation industry,” the scientists said. “It is a big step toward realizing solar-made fuels.”
Similar to other STCH designs, the conceptual system can be built around an existing CSP plant, absorbing the receiver’s heat and directing it to split water and produce hydrogen. However, there is a novel two-step thermochemical reaction at the heart of the new sys
