Scalable, Sustainable, and Manageable Power from Renewable Innovations at Rebelle Rally 2025
This year’s 10th Annual Rebelle Rally, the longest competitive off-road rally in the United States began on October 9 in Mammoth Lakes, California. The event features 68 two-person teams competing over nine days of stages, across Nevada and California’s iconic terrain. Precision driving and navigation, not speed, are the ultimate goals, relying solely on maps, compasses, and roadbooks. The rally competition concludes October 17 in Needles, California, with Rebellation, the awards gala, on October 18.
For the last five years, Renewable Innovations has been the Power Partner, keeping the Rebelle Rally powered up wherever the off-road course takes them. This year, the 2025 Rebelle Rally will showcase Renewable Innovations’ advancements in sustainable energy solutions, particularly focusing on hybrid hydrogen fuel cell microgrids. This year's event aims to not only challenge participants in navigation and endurance but also to serve as a real-world demonstration of scalable and manageable energy systems in remote and demanding environments.
The Rally's infrastructure will be powered by Renewable Innovations’ Mobile Microgrid. This integrated system combines the power of solar-fed MEC-S (Mobile Energy Command - Solar) system, the MEC-H (Mobile Energy Command - Hydrogen) hydrogen fuel cell systems, a total of up to 700 kWh of battery storage, large-scale high power isolation multi-voltage distribution network, and the Virtual H2 Pipeline. The MEC-S and its SmartFlower can generate enough power for 5 homes. The ¾ MW MEC-H delivers power for 75 homes directly from the mobile system. Additionally, the systems are nearly silent operations and produce no emissions, making them ideal for indoor, outdoor, or remote operations. Together, these systems create a robust and resilient energy network across the base camps demonstrating the practical application of high-density energy resilience.
"Our Mobile Microgrid, featuring the solar-fed MEC-S and hydrogen fuel cell MEC-H systems, combined with substantial battery storage and supply of Hydrogen, represents a significant leap in scalable, sustainable, and affordable grid-free power. This comprehensive energy network ensures that the Rebelle Rally operates seamlessly, demonstrating the practical application of sustainable solutions in the most challenging environments," said Robert Mount, CEO of Renewable Innovations. “If we can deliver nearly 1MW of power in the middle of the desert, we can do it anywhere - including data centers, ports, and emergency operations centers.”
This year's Rally will feature a significant demonstration at the final base camp. Renewable Innovations and Toyota are collaborating to validate the paralleling and integration of the Toyota fuel cell module into the Renewable Innovations' Mobile Microgrid. The Toyota Tundra pickup truck bed contains the Toyota hydrogen fuel cell generator, which can deliver significant three-phase, industrial-grade power when connected to a hydrogen supply.
This demonstration will provide insights into scalable high-density energy resilience while also showing seamless integration of multiple power sources into the Renewable Innovation’s Mobile Microgrid, enabling manageability and sustainability in a remote-off-grid application.
"Toyota’s collaboration with Renewable Innovations’ Mobile Microgrid at the Rebelle Rally demonstrates both the capability and scalability of hydrogen fuel cell technology,” said Debby Byrne, executive program manager, Toyota Motor North America R&D.
