The Hydrogen Stream: Fuel cell solutions for electrical peak load coverage

Rolls-Royce is supplying its mtu hydrogen technology for the container terminal currently under construction at the Port of Duisburg in Germany. Furthermore, German energy company RWE wants to produce green hydrogen at the Pembroke Power Station site in Wales and Norway’s Scatec discussed plans for large-scale seawater desalination, hydrogen and ammonia production based on renewable power with the Egyptian government. Meanwhile, the EU has adopted a set of legislative proposals to decarbonize the EU gas market by facilitating the uptake of low carbon gases, including hydrogen.

Solar redox flow cell for residential energy storage

The device was designed by scientists in Portugal to optimize light absorption by the semiconductor and ensure an effective diffusion of redox species while offering minimal electronic and ionic transport resistance. The cell has a 25cm2 photoactive area and relies on ferrocyanide/anthraquinone redox flow chemistry and a nanostructured hematite photoelectrode.
