Researchers from the Laboratory of Renewable Energy Science and Engineering at Switzerland’s Ecole Polytechnique Federale de Lausanne have developed a device which they say could “provide a pathway for device scalability aimed towards the large scale deployment of photo-electrochemical hydrogen production”. Scientists at the Ecole Polytechnique Federale de Lausanne (EPFL) have developed a device to directly convert sunlight into hydrogen. By integrating a solar concentrator and smart thermal management system, the Swiss team says its device can achieve a stable 17% solar power-to-hydrogen conversion rate. The device is described in the paper A thermally synergistic photo-electrochemical hydrogen generator operating under concentrated solar irradiation, published in Nature Energy.
