Project with CleanTech and Calvera Hydrogen

Hydrogen powered city buses in Denmark

Three hydrogen-powered buses were taken into public transportation service in Aalborg, Denmark, in the spring of 2020. The fuel cell emission-free electric buses are fueled by hydrogen produced on-site at the refuelling station on a GHS HyProvide™ A-series based on solar power. The hydrogen buses are estimated to save about 60,000 litres of diesel fuel each year and reduce CO2 emissions by 131 tons annually.

Green Hydrogen Systems typically serves as an OEM component supplier, providing electrolysers to companies that produce or integrate hydrogen refuelling stations and other types of hydrogen-producing facilities. In this case, the company also took on the role of EPC, dimensioning the system in terms of capacity, redundancies and other factors. GHS called on Spanish partners Clan Tecnológica (Clantech) and Calvera to provide the facility’s storage, compressor and dispenser technologies.

HyProvide™ X-series

The X-Series is based on the existing well-proven technology, optimised for use in the growing market for large-scale applications in, for example, industry, energy and heavy-duty transport sectors. Its unique multi-stack concept allows the electrolyser to reach higher voltages crucial to utilise mass-produced, low-cost and high-efficiency power electronics from wind and solar markets operating in the 1000-1500V range.
