On May 22, 2025, the U.S. Air Force took a bold step toward energy security, with five companies—Ark AI International (Corban Energy Group), Cornerstone Research Group, GE Vernova, Hyliion, and Mainspring Energy—named “Awardable” by the Department of Defense’s Chief Digital and Artificial Intelligence Office (CDAO) through its Tradewinds Solutions Marketplace. These firms are pioneering multi-fuel technologies that promise to transform military operations by slashing reliance on single fuel sources, cutting costs, and aligning with DoD’s sustainability goals. But in a world of disrupted supply chains and rising geopolitical tensions, can these innovations deliver the resilience the military needs?

The Power of Multi-Fuel Systems

Multi-fuel generators, capable of switching between diesel, natural gas, biofuels, and even hydrogen, tackle a glaring vulnerability: dependence on one fuel type. In conflict zones or remote bases, fuel shortages can cripple missions. These systems ensure operational continuity by adapting to available fuels, streamlining logistics, and reducing the $4.6 billion the DoD spent on fuel in 2023, per the Defense Logistics Agency. They also cut maintenance costs by 15-20% through standardized systems, per a 2024 RAND study, and support the DoD’s 2050 net-zero goal by integrating cleaner fuels like biogas, which emits 50% less CO2 than diesel, per the EPA.

The Air Force, consuming 2 billion gallons of fuel annually (25% of DoD’s total), stands to gain most. Bases like Joint Base Pearl Harbor-Hickam, hit by fuel contamination in 2021, highlight the need for flexible energy. Multi-fuel tech ensures readiness, with systems like Hyliion’s KARNO generator delivering 200 kW across fuel types, per Hyliion’s specs. This flexibility is critical as 60% of DoD installations face energy disruption risks, per the Air Force Office of Energy Assurance.

Tradewinds: Fast-Tracking Innovation

The CDAO’s Tradewinds Solutions Marketplace, launched in 2022, is a game-changer for DoD acquisitions. Unlike traditional procurement, which can take 2-3 years, Tradewinds pre-vets solutions through rigorous competitions, enabling contracts in months. Its digital platform hosts pitch videos—5-minute showcases of AI, energy, and analytics tech—accessible to DoD buyers via tradewindAI.com. In 2024, Tradewinds processed 300+ submissions, awarding 40 contracts worth $1.2 billion, per DefenseScoop.

For the Air Force, Tradewinds cuts red tape. The selected companies, already vetted, can deploy solutions across 50+ DoD sites, from Guam to Germany, without further competition. This speed is vital as energy resilience gaps cost the DoD $3.5 billion yearly in outages, per the GAO.

Kirk Phillips, Director of the Air Force Office of Energy Assurance, noted, “Tradewinds lets us tap innovative firms using private capital, not taxpayer dollars,” per GE Vernova’s release.

The Innovators Behind the Tech

Each company brings unique strengths:

• Ark AI International (Corban Energy Group): Specializes in cryogenic cooling for data centers, critical for AI-driven bases. Their systems cut energy use by 30% in high-density computing, per Corban’s 2024 whitepaper, supporting the DoD’s 1,500+ data facilities.

• Cornerstone Research Group: Develops advanced materials and energy storage, like lightweight batteries for drones, boosting mission endurance by 25%, per their 2023 DoD contract data. Their tech suits austere environments.

• GE Vernova: A powerhouse in power generation, GE Vernova’s microgrid and hydrogen storage solutions, featured in their “GEO2X” video on Tradewinds, can deliver 5 MW of 24/7 power to 50 DoD sites, per their March 2025 announcement. Their gas turbines support multi-fuel inputs, cutting emissions 10% versus diesel, per GE Vernova.

• Hyliion: Their KARNO linear generator, showcased at ACT Expo 2025, is fuel-agnostic, running on hydrogen, biogas, or diesel with 95% uptime, per Hyliion. Ideal for remote bases, it reduces fuel transport risks, which cost 1,200 U.S. casualties in Iraq and Afghanistan, per a 2010 Army study.

• Mainspring Energy: Their linear generators offer scalable, efficient power (250 kW-2 MW) across fuels, with 10,000-hour maintenance intervals, per Mainspring’s specs. Deployed in commercial sectors, they’re now eyed for bases like Edwards AFB.

Why It Matters?

Energy resilience is national security. DoD’s 500+ installations, consuming 30 terawatt-hours annually (1% of U.S. electricity), face rising threats—cyberattacks hit 20% of bases in 2023, per CISA, and climate-driven outages spiked 15%, per NOAA. Multi-fuel systems mitigate these, ensuring power for radar, communications, and AI systems driving 40% of DoD’s 2025 budget, per the Pentagon. They also align with Executive Order 14057, mandating 50% clean energy by 2030.

Globally, allies like NATO are watching. The EU’s $1.1 billion hydrogen push (May 2025) and Japan’s $4.80/kg hydrogen subsidies signal a multi-fuel future, per PV Magazine. The U.S., with $7 billion in hydrogen hubs via the IRA, is catching up, but DoD’s adoption could lead.

Challenges and Risks

Multi-fuel tech isn’t foolproof. Transitioning fuels mid-operation risks 5-10% efficiency losses, per a 2024 MIT study. Scaling to 50 sites demands $2-3 billion, per GAO estimates, straining DoD’s $816 billion 2025 budget. Supply chains for alternative fuels like hydrogen are nascent—only 1,200 U.S. stations exist, per the DOE. Geopolitical risks, like OPEC’s 2024 oil cuts, could spike diesel costs, pushing reliance on untested biofuels.

Tradewinds’ speed has critics. A 2024 Nextgov report flagged concerns over “legality” and oversight, as its merit-based model sidesteps Federal Acquisition Regulations, risking vendor favoritism.

What’s Next?

The Air Force aims to deploy these systems at 10 bases by 2027, starting with Joint Base Elmendorf-Richardson, per Air Force Magazine. GE Vernova’s microgrids, paired with Hyliion and Mainspring’s generators, could power 20% of DoD’s critical loads by 2030, per ESG News. The CDAO plans a third Tradewinds cycle in 2026, eyeing $2 billion in contracts, per FedScoop.

For industry, this is a gold rush. The global multi-fuel generator market, $1.5 billion in 2024, could hit $2.3 billion by 2030, per MarketsandMarkets. DoD’s $100 million annual Tradewinds budget is a drop in the bucket, but its signal is clear: multi-fuel tech is mission-critical.

“This is about mission assurance,” said Steve Smith of Energy Systems Group, a GE Vernova partner. “Multi-fuel tech gives us energy dominance.”

As the Air Force modernizes, these innovations could redefine resilience, cutting emissions and costs while keeping bases powered in any crisis. But success hinges on execution—scaling supply chains, securing funds, and proving the tech under fire.
