Scientist hails commercial feasibility of Saudi Arabian hydrogen city plan

Alberto Boretti was a senior research professor at Prince Mohammad Bin Fahd University in 2021 when he first started discussing the idea of a hydrogen city in Al Khobar, Saudi Arabia. The New Zealand-based independent tells pv magazine that it is now commercially feasible, as the city’s 200 MW of energy demand would necessitate 1 GW to 1.3 GW of solar and wind capacity, 509 MW to 997 MW of electrolysis capacity, and 145,000 MWh of hydrogen storage capacity.
