GM believes these mobile charging stations can charge 100 cars before refilling the fuel cell

General Motors has been one of the pioneers of electric powertrains with the Bolt EV. In 2021, it doubled down on the electric powertrain with the Hummer EV, and recently at the CES trade show, it also revealed the Silverado EV that would be its latest mass-market electric play. But with its full focus on electric cars, GM hasn’t given up on fuel cell technology. It’s already harnessing its power for trucking, aerospace and even engines, but it’s now adapting this technology to hydroelectric-based power generators, which it believes Electric car can help with fast charging.
It has developed the second generation Hydrotech Fuel Cell Power Cube which will include a mobile power generator that can enable fast charging for electric cars without the need for a permanent charging point. An Empower rapid charger could help retail fuel stations offer affordable DC fast charging without expanding the grid. The Empower rapid charging station which is based on these fuel cell cubes can charge four 150 kW cars simultaneously within 20 minutes. GM estimates that a rapid charger with a full tank of hydrogen could potentially charge 100 EVs before it needs to be refilled. That’s why Empower rapid chargers are expected across the US – with 500 by the end of 2025.
The mobile charging station can simultaneously charge up to 4 cars at a speed of 150 kW
It can also be used to quietly and efficiently power military camps.
“Our vision of an all-electric future is broader than just passenger vehicles or even transportation. Our energy platform expertise with the Altium vehicle architecture and propulsion components and Hydrotech fuel cells helps reduce emissions while helping to reduce many different- could expand access to energy across different industries and users, often linked to power generation,” said Charlie Freese, GM’s executive director of global HYDROTEC business.
GM believes these generators could eventually replace generators that burn petrol and diesel, resulting in lower emissions while also serving as a backup for grid-based energy. Hydrotech based generators have a power output of 60 kW to 600 kW with zero emissions and low noise and heat signature.
MPG can also be used by the US military
It is already supplying these power cubes to Linden’s Renewables Innovations in Utah to make mobile power generators (MPGs) that will provide fast charging capability for EVs. There are also a number of development projects for these MPGs that are funded by, for example, the Michigan Economic Development Corporation and the US Army Combat Capability Development Command Ground Vehicle Systems Center. The first version of the MPG will be shown in 2022.

Even the California Energy Commission is funding a separate demonstration program for an additional four MPG through its Mobile Renewable Backup Generation Program. The program intends to explore how hydrogen-based mobile electricity can help offset the loss of energy during planned power shutoffs used to reduce massive wildfires in the state.
