Researchers at the University of Exeter in the United Kingdom conducted a study on a 1 GW off-grid agrivoltaic facility for hydrogen generation to fuel electric vehicles in Australia, California, China, Nigeria, and Spain. The project aims to provide a levelized cost of hydrogen between $3.90/kg to $8.13/kg. The study found tomatoes to be the best crop for cultivation under the solar panels, with potential agricultural yield losses ranging from 9.40% to 36.94%. The techno-economic analysis considered various factors like NPV, IRR, total profit, and LCOH, showcasing the feasibility of the project. This innovative approach not only offers a sustainable energy solution but also enhances land utilization and provides additional income through electricity generation. The research highlights the benefits of combining agrivoltaics with hydrogen generation for a greener future.
