Researchers have built a kilowatt-scale pilot plant that can produce both green hydrogen and heat using solar energy. The solar-to-hydrogen plant is the largest constructed to date, and produces .
The trend of efficiency shows that the highest solar-to-H 2 efficiency, amounting to ∼32%, is obtained for photovoltaic–electrochemical systems, followed by photoelectrochemical systems (∼19%), then photocatalytic and photobiological systems (1–3%), and finally solar thermochemical systems (<1%).
This study employs high-grade solar energy within the short-wave spectrum for photovoltaic purposes, and low-grade solar energy in the long-wave spectrum for thermochemical applications. Such cascaded exploitation of the full solar spectrum significantly improves solar energy utilization efficiency.
A mixed-integer linear programming model was utilized to analyze optimal operation procedures. Three different cases were compared and evaluated, including (1) CO 2 emission, (2) Capacity utilization of the renewable energy resource hydrogen refueling station, and (3) Operational cost.
