Hydrogen-fueled cars have become increasingly popular in California, though they still account for a tiny fraction compared to the number running on gasoline. Getting those vehicles to move beyond the state’s borders may require 18-wheelers crisscrossing America’s highways leading the way.
Research at the National Renewable Energy Laboratory (NREL) suggests a shift in long-haul trucking toward hydrogen, which would necessitate a coast-to-coast network of fueling stations.
Before that can happen, however, scientists must answer certain questions.
“That’s an area industry is very much looking for help with,” said Keith Wipke, manager of NREL’s Fuel Cell and Hydrogen Technologies program. “What are the bottlenecks? What are the challenges? What are the fueling methods and protocols that should be adopted? The addition of heavy-duty hydrogen vehicle research is important for the program, as it is a market with a big impact on energy use and emissions.”
