DOE awarding combined $127M to 5 Supertruck 3 projects; battery-electric and fuel cell trucks
Canadian Pacific expands hydrogen locomotive program; additional locomotives, fueling stations; $15M from ERA

DOE awarding $71M to 20 RD&D projects to cut GHG emissions, expand EV infrastructure; $5M to Achates for opposed-piston 2-stroke hybrid

The US Department of Energy (DOE) is awarding $71 million to 20 research, development, and demonstration (RD&D) projects with industry, academia, and non-profits including Clean Cities Coalitions for the creation of solutions to reduce greenhouse gas emissions for on- and off-road vehicles and to accelerate the expansion of EV infrastructure and charging. (DE-FOA-0002475, earlier post.)

Projects will work to lower emissions by leading the expansion of EV charging stations to facilitate the transition from fossil fuel-powered vehicles to electric vehicles. This includes EV charging community projects, such as installing charge stations within multi-unit housing, hosting community-led demonstrations that address barriers to EV adoption and lowering costs for direct current (DC) fast charging equipment.

Of the $71 million, Achates Power will receive $5 million for work on an opposed-piston 2-stroke hybrid commercial vehicle system, and Cummins will receive $4 million for its work on an ultra-low emissions heavy-duty 10L natural gas engine.

Nice to see that Achates receives funding. However, I cannot comprehend why it has to be combined with a hybrid drive at this stage. This is of course a possible option, and probably require some additional work in comparison to a traditional piston engine, but the priority now should be to complete engine development and make it ready for production. Hybridization can wait.
