The two Energy Innovation Hubs will accelerate development of storage technology beyond lithium-ion batteries, with a priority on use of inexpensive and abundant materials.

The use of hydrogen, both for transportation fuel and blended into natural gas, is a hot topic among engineers and power producers.

Combustion without pollution? A hybrid diesel engine could be a contender as the best technology for heavy long-distance trucking.

Scientists and engineers from two national labs began a four-year project with locomotive maker Wabtec aimed at using hydrogen in diesel-electric train engines.

The DOE wants to cut the cost of lithium-ion batteries, recharge EVs with a 300-mile range in 15 minutes and boost battery recycling — all in the next decade.
