How can a car drive on water?
A system developed by the EU-funded SWITCH project can deliver a stable supply of low-carbon hydrogen-based electricity, such as for transport refuelling stations, by alternating between different energy sources. “The same system can be fed by electrical power, renewable power and water electrolysis processes, switching between them as necessary,” explains project coordinator Matteo Testi. The project has now been featured in the CORDIS series of explanatory videos titled ‘Make the connection with EU science’. When renewable energy is available, the system uses electricity, water and heat to produce green hydrogen, with no emissions. In the absence of renewable electricity, the SWITCH system uses natural gas or biomethane to produce grey or green hydrogen as well as electricity. ‘Make the connection with EU science’ is a series of explanatory videos focusing on the scientific content and exploitation aspects of EU research projects.
