Aluminum’s Energy Revolution: How a Boston Startup Is Turning Scrap Metal into Industrial Fuel

The Aluminum Energy Breakthrough

In a Boston laboratory surrounded by a maze of pipes and wires, Peter Godart and his team at Found Energy are preparing for what could become one of the most significant real-world tests of aluminum as a zero-carbon fuel. The startup has developed technology that rapidly releases energy from aluminum scraps to power industrial processes, potentially offering a viable alternative to fossil fuels for heat-intensive manufacturing operations.

Found Energy recently activated what Godart claims is the largest aluminum-water reactor ever constructed. Early next year, this system will be installed at a tool manufacturing facility in the southeastern United States, where it will provide both heat and hydrogen using the plant’s own aluminum waste as fuel. The manufacturer has chosen to remain anonymous until the project’s formal announcement, but if successful, this demonstration could pave the way for broader adoption across multiple industries., according to additional coverage

Why Aluminum as Fuel?

Engineers have long been intrigued by aluminum’s potential as an energy source due to its remarkable energy density. Once refined and smelted from ore, aluminum metal contains more than twice as much energy as diesel fuel by volume and nearly eight times as much as hydrogen gas. When aluminum reacts with oxygen in water or air, it forms aluminum oxides while releasing substantial heat and hydrogen gas—both of which can be harnessed for zero-carbon power generation., according to recent innovations

“We invented the fuel, which is a blessing and a curse,” Godart explains from his laboratory. “It’s a huge opportunity for us, but it also means we do have to develop all of the systems around us. We’re redefining what even is an engine.”, according to expert analysis

The Aluminum Reaction Challenge

The fundamental problem with using aluminum as fuel—and the reason aluminum soda cans don’t spontaneously combust—lies in the metal’s self-protecting oxidation mechanism. As soon as aluminum begins reacting with water or air, a protective oxidized layer forms across its surface, preventing further reaction. This natural passivation acts like a fire that generates its own extinguishing agent., according to technological advances

“People have tried it and abandoned this idea many, many times,” acknowledges Godart, reflecting on the historical challenges that have prevented aluminum from becoming a practical fuel source.

Scientific Skepticism and Historical Context

Not everyone in the scientific community believes aluminum can become a viable fuel. Geoff Scamans, a metallurgist at Brunel University London who spent a decade working on aluminum-powered vehicles in the 1980s, remains skeptical. “This potential use of aluminum crops up every few years and has no possibility of success even if aluminum scrap is used as the fuel source,” Scamans states. He argues that the aluminum-water reaction isn’t efficient enough to justify using the metal as fuel, particularly considering the substantial energy required to refine and smelt aluminum from ore initially.

Found Energy’s Catalytic Breakthrough

What sets Found Energy’s approach apart is their novel catalytic process. “The real breakthrough was thinking about catalysis in a different way,” Godart reveals. Instead of conventional methods that focus on bringing water and aluminum together on a catalyst surface, the company “flipped it around” and developed a liquid metal catalyst that dissolves into the aluminum itself.

This catalyst permeates the aluminum’s microstructure, causing the metal to froth and split open as it reacts with water. This continuous exposure of unreacted aluminum to water maintains the reaction, overcoming the historical limitation of surface passivation. The process efficiently generates both high-temperature heat and hydrogen gas from what would otherwise be considered industrial waste., as covered previously

Industrial Applications and Climate Impact

The technology holds particular promise for industries that require high-temperature heat and are difficult to decarbonize through electrification alone. Cement production, metal refining, and various manufacturing processes generate substantial greenhouse gas emissions primarily from thermal requirements that electricity often cannot efficiently provide.

• Waste-to-energy conversion: Transforming aluminum scrap into useful energy
• Dual output: Simultaneous production of heat and hydrogen
• Industrial decarbonization: Potential to significantly reduce fossil fuel dependence in manufacturing
• Circular economy: Creating value from what would otherwise be waste material

The Road Ahead

The upcoming installation at the tool manufacturing facility represents a critical milestone for Found Energy’s technology. If successful, it could demonstrate aluminum’s viability as a zero-carbon fuel at commercial scale. The company’s approach of using industrial scrap as fuel source addresses both waste management and energy generation challenges simultaneously.

As Godart and his team prepare for their largest real-world test to date, the industrial and environmental communities will be watching closely. The success or failure of this demonstration could determine whether aluminum finally transitions from periodic curiosity to practical solution in the global effort to decarbonize industrial processes.

The coming months will reveal whether Found Energy’s catalytic innovation can overcome decades of skepticism and technical challenges to make aluminum a legitimate player in the clean energy transition.
