The greatest challenge for fuel cell mobility is the availability of hydrogen fuel and refuelling infrastructure, according to a new IDTechEx report.
The lack of hydrogen refuelling infrastructure has hindered fuel cell vehicle rollout for at least the past decade, the report states, although Japan, Korea, Germany, California and China are supporting initiatives to address the problem.
Hydrogen fuel used in transportation is primarily grey hydrogen produced by steam methane reforming of natural gas, which at best, offers a “very limited” carbon dioxide (CO2) emission reduction over modern combustion engines, according to IDTechEx.
Several recent announcements have been made about funding support to produce low-carbon blue and green hydrogen. In September, the EU approved $5.2bn in public funding for green hydrogen projects, and the US announced plans for a $7bn investment to establish up to 10 regional hydrogen hubs.
