Switzerland is set to lead a groundbreaking clean energy initiative by installing solar panels on active railway tracks, a world-first innovation developed by Swiss start-up Sun-Ways with the Swiss Federal Institute of Technology Lausanne (EPFL). This unique project, scheduled to launch in Neuchâtel by 2025, aims to generate 16,000 kWh annually, with the potential to expand across Swiss rail networks and contribute up to 1 TWh yearly, accounting for 2% of the nation’s energy needs.

The system, described as a "solar carpet," features removable panels laid between railway tracks without obstructing train movement. Installed via a specialized train, it allows for quick setup and easy removal for track maintenance. Joseph Scuderi, CEO of Sun-Ways, emphasized the importance of its removability, a key advantage over previous solar projects that could not be adapted for active railway lines.

Funded with CHF585,000 (€623,000), the three-year pilot will cover a 100-meter stretch near Buttes station in Neuchâtel. Initially, the electricity generated will power local homes rather than rail systems due to operational constraints, though future phases may address grid integration challenges.

Beyond Switzerland, Sun-Ways envisions a global market for this technology, exploring feasibility studies for other countries, including Spain, South Korea, and Australia. Co-founder Baptiste Danichert estimates that 50% of the world’s railways could accommodate this technology, creating a vast, renewable energy source.

Despite its promise, the project has met skepticism. Concerns from the International Union of Railways about durability and potential fire risks prompted Sun-Ways to reinforce the panels with anti-reflective surfaces. Addressing winter challenges, the company is developing technology to prevent ice accumulation, ensuring reliable year-round operation.

If successful, this pioneering project could set a global standard, aligning with international goals for reducing carbon footprints by using existing infrastructure for renewable energy generation.
