The Mobile Energy Command is a 53-foot semi-trailer that arrives as a complete fast-charging plaza and megawatt-class power plant, hundreds of miles from the nearest grid connection.
Up to 640 kW of hydrogen fuel-cell generation feeds a 440+ kWh battery buffer, two dual rapid-DC charge units and four PHEV outlets, so four vehicles fast-charge simultaneously in 15 to 20 minutes, with up to 750 kW available for other loads.
Grid-interactive where a grid exists. Grid-independent where it doesn't.
Watch the trailer run a plaza: hydrogen in, fuel cell and battery buffer in the middle, four vehicles drawing 180 kW each. Plug a vehicle in or out of any bay to see the load change.
Illustrative simulation at rated output: 180 kW per vehicle, typical charge 15–20 minutes, one plaza minute every 0.6 seconds. Actual sessions depend on each vehicle. The trailer also carries four PHEV outlets, not shown.
The MEC Hydrogen pairs with RI's Virtual Pipeline hydrogen trailers: 800 kg at 250 bar, or 1,200 kg at 350 bar. One trailer swap replenishes the entire operation, with no pipeline, no utility upgrade and no fuel that degrades in storage.
Two dual rapid-DC units charge four vehicles simultaneously at 180 kW each, with four more PHEV outlets alongside, 15 to 20 minutes per charge. Fleet depots, launch events, dealer networks and highway corridors get charging capacity the day the trailer arrives; one MEC trailer is already leased to a major EV taxi company.
Up to 750 kW of AC at 120/208 or 480 Delta serves base camps, job sites, emergency operations and facilities waiting on an interconnect. Run it grid-interactive to support a weak feed, or fully grid-independent: the same trailer that charges the fleet carries the site.

Since 2021, Renewable Innovations has been the official power partner of the Rebelle Rally, a 2,500-kilometer competitive off-road rally across the Nevada and California desert with no grid in sight. The MEC Hydrogen is the system that keeps the electric field running, night after night.
Consecutive years, 2021 to 2025
Of desert course, powered grid-free
Supported over 8 competition days in 2023
People kept running at base camp
In 2023, a Rivian R1T became the first electric vehicle to win the Rebelle Rally outright, charged every night by this system, on green hydrogen, in the middle of the desert. Over the same event, the MEC Hydrogen fast-charged Rivian, Ford Mustang Mach-E, Jeep, BMW and VW entries, keeping a dozen competition EVs on course for eight straight days.
When the vehicles that must not run out of charge are 2,500 kilometers into the sand, the charging infrastructure is the race-critical system. It held.
During MotorTrend's 2022 SUV of the Year testing, an RI mobile charging trailer charged 13 EVs, keeping an entire press test fleet moving without a grid connection.
At the OPTIMA Oasis in Johnson Valley, California, RI ran four Level 3 and ten Level 2 chargers entirely on hydrogen and solar: a working charging plaza in open desert, as reported by The Verge.
“No one came close to the experience, organization, and contingencies provided by Renewable Innovations.”
Every MEC Hydrogen is monitored 24/7 from the RI Network Operations Center. It is modular and expandable, and pairs with MEC Solar and Virtual Pipeline trailers as the site grows.
“If we can deliver nearly 1 MW of power in the middle of the desert, we can do it anywhere, including data centers, ports, and emergency operations centers.”
