Freight rail sits at a crossroads. While it remains one of the most efficient logistics modes globally, its energy foundation, diesel combustion, has become increasingly incompatible with both cost pressures and climate targets.
Voltify is entering the market with a thesis that the problem is not rail itself, but the way rail is powered.
The company announced a $30 million seed round co-led by Aleph and Fortescue, alongside additional strategic investors and angels. The funding will support early deployments of its distributed rail energy platform across U.S. and global corridors.
Founded by Dafna Langer and Alon Kessel, Voltify is building what it describes as a “rail-native energy network.”
Diesel Economics vs Electrification Reality
Rail operators in the United States collectively spend around $11 billion annually on diesel fuel. However, replacing that system with overhead electrification would require infrastructure investments exceeding $1 trillion.
That imbalance has left the industry locked in place.
Voltify’s approach targets a middle path: reducing energy costs by more than 20% without requiring operational disruption or large-scale capital deployment.
“We built Voltify to solve one of the rail industry’s biggest challenges: energy costs,” said Langer, Co-founder and CEO of Voltify. “Our platform allows rail companies to access clean, affordable energy without changing the way they operate. If you can reduce energy costs by even 5%, it’s huge. If you can reduce them by more than 20%, it becomes transformative.”
A System Designed Around Motion, Not Infrastructure
Voltify’s architecture eliminates reliance on fixed overhead wiring, instead combining mobile energy systems with distributed microgrids and dynamic charging while trains are in motion.
The result is a continuous energy supply chain that replaces stationary infrastructure with a flexible grid embedded along rail corridors.
“Importantly, the company’s model removes the so-called “green premium. Our goal is to lower energy costs by over 20%; this is not just the diesel costs, but all the next energy that the industry needs,” Langer said. “Rail companies shouldn’t have to choose between sustainability and economics. We’re making clean energy the financially smarter option.”
Strategic Backing From Energy and Mining Giants
“Voltify is redefining the energy supply chain for global rail networks”, said Tomer Diari, General Partner at Aleph. “Their electricity-based solution will help rail operators dramatically reduce costs, pollution, and dependency on diesel, and make transporting goods in the US cheaper and more reliable for everyone.”
Fortescue framed its investment as part of a broader industrial decarbonization strategy.
“Fortescue is committed to investing in the research and development of innovative technologies to drive Real Zero and accelerate decarbonisation across our operations and beyond. Voltify’s mission to eliminate emissions in the heavy rail industry aligns with ours at Fortescue, and we’re encouraged by the solutions they are working on,” said Gus Pichot, CEO Growth & Energy at Fortescue.
Early Signals of Market Adoption
Voltify has already secured a paid pilot with one of the largest Class I rail operators in the world, with deployment scheduled in the coming months. Interest is also building across regional operators seeking cost reductions and emissions compliance solutions.
