DOE also announced up to $35 million to advance fuel cell and hydrogen technologies, including enabling the early adoption of fuel cell applications, such as light duty fuel cell electric vehicles. This new funding opportunity announcement will be available in early February. Reducing the cost of electric drive systems from $30/kW to $8/kW.

The HPE was long thought to be a system in which all engine valves had to be actuated in a fully variable manner to allow for two-stoke pneumatic modes and still enable the four-stroke combustion mode. In large naturally-aspirated SI engine, high-friction, pumping losses and part-load operation all contribute to poor fuel efficiency.
