On Wednesday, October 29, 2025, Coalition for Clean Air (CCA) joined RockeTruck and Cal State LA for the public unveiling of a game-changing innovation: a hydrogen-powered Mobile Fuel Cell Generator (MFCG) that can charge electric vehicles and deliver clean energy wherever needed.
The event took place at Cal State LA’s Hydrogen Research and Fueling Facility, a fitting location given the university’s leadership in clean transportation and its commitment to economic social mobility. RockeTruck chose Cal State LA not just for its technical expertise, but for its deep ties to the community — including students from historically underrepresented backgrounds most impacted by pollution who helped shape the project.
Cal State LA integrates the lessons learned into its fuel cell curriculum and workforce training at the HRFF. Cal State LA graduate students perform optimization study to improve the performance.
So what makes this generator special? It’s compact, mobile, and zero-emission. It runs on hydrogen and produces up to 60kW of continuous power — enough to charge EVs, power homes, street lights, and evacuation centers during emergencies, or support large outdoor events.The integrated 70 kWh battery allows the generator to operate up to 120 kW for 10 min or so.Unlike diesel backup generators, which emit harmful pollutants like fine particulate matter (PM₂.₅), smog-forming oxides of nitrogen (NOₓ), and carbon dioxide (CO₂), this unit offers a clean alternative with quiet operation and the ability to start generating electricity in just one minute!
The generator’s design is clever too: it’s built like an IKEA kit — no welding required — and uses a mix of off-the-shelf and custom inverters to convert hydrogen fuel cell direct current (DC) output into the more commonly used alternating current (AC) power. It even includes a bright orange EV charger that can handle high energy loads (think 90+ hair dryers running at once!).
Over the past three years, RockeTruck refined the design from a bulky prototype to the sleek version we saw at the event. It’s mounted on a trailer that can run for up to 48 hours and may eventually be towable by an EV truck. In the future, lighter versions will be available for purchase, expanding access to clean, mobile power.
As California pushes toward a zero-emission future, innovations like this are key — and so is community engagement. That’s where Coalition for Clean Air comes in. Our role is to make sure the public understands what’s possible and why it matters. RockeTruck’s event was a powerful reminder: Clean energy isn’t just coming — it’s already here, and it’s rolling in on wheels!
