GeoPura and the Ministry of Defence have successfully completed a landmark hydrogen power trial introducing hydrogen on military bases to generate electricity for charging electric vehicles. This trial, the first military application of the technology, focused on implementing an alternative Battery Electric Vehicle (BEV) charging capability using zero-emission green hydrogen-powered generators (HPUs) at key MOD locations. The deployment of GeoPura HPUs proved critical to the trial's success, offering reliable and environmentally friendly power to support the scaling of rapid electric vehicle fleet charging infrastructure. The trial showcased the potential of hydrogen as a key enabler of the MOD's transition to zero-emissions energy, overcoming challenges posed by expanding electric vehicle fleets. With approximately 120,000 miles driven in vehicles charged via HPUs during the trial, hydrogen has proven to be a robust and sustainable alternative to meet increasing electricity demands. Looking ahead, GeoPura aims to further deploy hydrogen across Defence sites, develop regulations for military hydrogen use, and enhance personnel training in hydrogen-based systems to drive decarbonization efforts on a larger scale. The successful collaboration between GeoPura and the MOD highlights the potential of hydrogen power in enabling sustainable energy solutions for Defence operations, paving the way for a greener and more resilient energy future.
