In what’s being hailed as a “completely unique” idea that could have “wide impact with commercial applications on electrified rail networks all over the world,” a new project in the UK could see electric trains powered by trackside solar panels that work independently from the main power grid.
The Guardian reports that Imperial College London has teamed up with climate change charity 10:10 to look into using trackside solar panels to power trains. As part of the project, researchers will investigate connecting solar panels directly to power lines that supply trains, in an effort to bypass the larger power grid and more efficiently manage power demand from trains.
Along with the aforementioned worldwide commercial applications, Imperial College said in a statement that if the research is successful, it would “also open up thousands of new sites to small and medium-scale renewable developments by removing the need to connect to the grid.
The Guardian notes that state-owned Network Rail is already investing billions of dollars toward electrifying railways in the UK, in an effort to get rid of polluting trains that run on diesel fuel. According to 10:10, this effort, combined with the growing production of renewable power in the country could add up to significantly less carbon emissions by 2050.
As many trains in the country run through rural areas where the electricity grid is tough to access, the plan to power trains with solar panels not connected to the grid could have widespread applications. The project’s first goal is to look at the feasibility of converting “third rail systems” that supply electricity through power lines close to the ground, which are used on about one third of the country’s tracks.
“I don’t think you get a better fit for PPA than a train line,” said Leo Murray of 10:10. “A rural train line even more so, the project would open up many investment opportunities across the country and further afield.”
