TECHNOLOGY REPORT ALTERNATIVE FUELS GM reveals hydrogen-fueled power generator and EV rapid-charger GM and Renewable Innovations are collaborating on an Empower rapid charger that can help retail fuel stations add DC fast-charging capabilities without significant investment in non-recoverable infrastructure upgrades. General Motors in January announced the expansion of commercial applications for its Hydrotec hydrogen fuel cells with an integrated DC rapid charger. The company currently is developing units intended for applications such as heavy-duty trucks, aerospace and locomotives, but it now is broadening the intended use to include stationary power generation. GM's Hydrotec-based power generators will be powered by the company's second-generation fuel cell power cubes. GM is supplying Hydrotec power cubes to Renewable Innovations of Lindon, Utah, who will manage the assembly of the mobile power generators. In addition to mobile EV charging, GM and Renewable Innovations have collaborated to develop the Empower rapid charger. This charger is intended for existing fuel stations seeking the ability to add DC fast charging capability. GM states the Empower rapid charger will help satisfy the growing need for fast charging infrastructure with no additional investment in electrical infrastructure upgrades. 10 March 2022 The rapid charger is powered by eight GM Hydrotec power cubes and can supply a DC charge for up to four vehicles simultaneously at a rate of 150 kW. The estimated target for a full charge time of an EV via these units is 20 minutes. GM claims up to 100 or more EVs can be replenished by the rapid charger before the unit would need to be resupplied with hydrogen. Renewable Innovations plans to deploy 500 Empower rapid chargers across the GM's mobile power generator can fast-charge EVs without having to expand the grid or install permanent charge points in locations where there is only a temporary need for power.
