Michael Grätzel at EPFL (Ecole Polytechnique Fédérale de Lausanne) in Switzerland has developed a highly efficient and low-cost water-splitting cell combining an advanced perovskite tandem solar cell and a bi-functional Earth-abundant catalyst. Currently, perovskite instability limits the cell lifetime.) Credit: EPFL.

Researchers from the US and Denmark have engineered a bio-inspired molybdenum sulfide catalyst as an inexpensive, abundant alternative to platinum and coupled it with a light-absorbing electrode to create a photo-electrochemical water splitting device to make hydrogen fuel from sunlight and water. —Hou et al.

The nanostructured photoelectrode results in spontaneous hydrogen evolution from water without any external bias applied with a faradaic efficiency of 30% and excellent stability. A promising way of storing solar energy is via chemical fuels, in particular hydrogen as it is considered as a future energy carrier.

Researchers from the University of Houston (UH) have developed a cobalt(II) oxide (CoO) nanocrystalline catalyst that can carry out overall water splitting with a solar-to-hydrogen efficiency of around 5%. The generation of hydrogen from water using sunlight could potentially form the basis of a clean and renewable source of energy.

Researchers from the Karlsruhe Institute of Technology (KIT) and their Canadian partners have designed a low-cost photoreactor design for solar-driven synthesis. Until now, however, the technology has mainly been found in the laboratory because the costs of producing solar hydrogen were simply too high.

As the fraction of electricity generation from intermittent renewable sources—such as solar or wind—grows, the ability to store large amounts of electrical energy is of increasing importance. Solid-electrode batteries maintain discharge at peak power for far too short a time to fully regulate wind or solar power output.

A team of researchers at MIT has described a framework for efficiently coupling the power output of a series-connected string of single-band-gap solar cells to an electrochemical process that produces storable fuels. Such a system would use sunlight to produce a storable fuel, such as hydrogen, instead of electricity for immediate use.
