Hyllion ERX - A Natural Gas Hybrid Electric Semi

This is Hyliion's new hybrid system. It is an electric truck with a natural gas powered generator to charge the battery. It can run EV only for 25 miles to enter EV only areas in cities and cruise 1,300 mile on a tank.

This is a great idea for a realistic way to transition long-haul trucking to alternative fuels. Natural gas stations already exist and NG trucks have very low emissions. It is likely actually simpler than a modern diesel truck with all the emission controls and little fuel economy tweeks.

Amazing it can hold enough CNG to run 1300 miles working a load. Or can it?

Using 6mpg, you need 216 gallons of diesel so perhaps 1000 gallon high pressure gas. The tanks shown look almost big enough for1/2 that, one on each side.

The CNG transit vans I drove had a 50 gallon tank where the gasoline tank was but I could only get maybe 60 miles out of it before refill. Some days I refilled 3 times.
