Austrian cleantech startup REPS GmbH has raised $23.6 million in equity financing to expand its technology that converts road traffic into clean electricity. The Tyrol-based company has developed the Road Energy Production System, a patented “road power plant” designed to capture mechanical energy from vehicles and turn it into usable power. The announcement positions REPS as one of the more unusual entrants in Europe’s energy-harvesting market, where startups are looking beyond wind and solar for new sources of renewable generation.
Funding to Scale Road-Based Energy Generation
The new capital will support REPS as it moves from early commercial validation toward broader deployment across transport and logistics infrastructure. The company has not publicly disclosed the lead investor in the round, while previous backers include EWOR, Clean Cities ClimAccelerator, and Austria’s Greenstart. Founded in 2023 by Alfons Huber, REPS has grown out of several years of research focused on recovering energy that is normally lost as vehicles move, brake, or pass over road surfaces.
How the Technology Works
REPS installs its system directly into existing roads, allowing trucks and cars to pass over the units without requiring new land or a separate energy facility. The company says the system captures kinetic and mechanical force from vehicle movement and converts it into electricity that can be used locally or fed into the grid. Its target locations include ports, logistics hubs, highways, airports, and urban infrastructure where heavy or frequent traffic creates repeatable opportunities for energy recovery.
Addressing Past Efficiency Challenges
Road-based energy harvesting has historically struggled with efficiency, maintenance requirements, and commercial viability, limiting its adoption beyond pilot projects. REPS claims its mechanical energy converter is significantly more efficient than earlier alternatives, with the company stating that its system reaches more than 90% energy conversion efficiency and is designed for over 20 years of durability under heavy traffic conditions. Those claims remain central to the startup’s pitch as it seeks to prove that traffic infrastructure can become a practical, scalable source of distributed clean energy.
Commercial Validation at the Port of Hamburg
The company’s first commercial system has been operating at Hamburger Container Service in the Port of Hamburg since November 2025. According to published reports, the 12-metre installation has already been crossed by more than 115,000 trucks and generated more than 6,700 kWh of electricity under real-world traffic conditions. The Port of Hamburg project gives REPS an important reference site in a high-traffic industrial environment where electrification, resilience, and emissions reduction are increasingly strategic priorities.
Strategic Relevance for Infrastructure and Energy
The timing of the funding comes as governments, ports, and industrial operators look for ways to diversify energy sources and reduce dependence on fossil fuels. REPS argues that roads are an underused asset because they already occupy large areas, carry predictable traffic flows, and can be upgraded without consuming additional land. Austria’s State Secretary for Energy, Startups and Tourism, Elisabeth Zehetner, has described the company as an example of how European startups can turn existing infrastructure into part of the clean-energy transition.
With fresh funding secured, REPS plans to scale its team from 12 employees to around 50 by the end of the year as it pursues international deployments. The startup’s immediate opportunity lies in transport-heavy environments such as ports and logistics centres, but Huber has framed roads as only the first use case for a broader mechanical energy-harvesting platform. If REPS can validate its efficiency, durability, and economics across more sites, its technology could add a new layer to renewable infrastructure by turning everyday vehicle movement into a local source of clean electricity.
