Assessment of the Potential for Green Hydrogen Fuelling of Very Heavy Vehicles in New Zealand

This study examined the feasibility of green hydrogen as a transport fuel for very heavy vehicle (VHV) fleet in New Zealand. Green is assumed to be produced through water electrolysis using purely renewable energy (RE) an electricity source. chose vehicles potential market hydrogen, because it considered “low-hanging fruit” sector where battery electrification less feasible. The large-scale, decentralized, embedded (dedicated) grid-connected system production polymer electrolytic membrane (PEM) electrolysers. analysis comprised three steps. First, demand was calculated. Second, additional RE requirement determined and compared with consented, but unbuilt, capacity. Finally, cost calculated concept levelized cost. Sensitivity reduction scenarios were also undertaken. results indicate overall VHVs 71 million kg, or 8.5 PJ, per year, 14.7 PJ diesel same VHV travelled kilometres. that estimated 9824 GWh could generated from yet projects greater than production, which 4492 GWh. NZD 6.83/kg. Electricity found most significant parameter production. A combined CAPEX translates 10 20 years.
