The researchers believe this new type of photoelectrode is not only cheap to produce, but can also be recreated on a larger scale for mass and worldwide use. Cost effective solar fuel generation is hindered by the semiconductor material not meeting certain essential criteria to achieve highly efficient solar to hydrogen conversion.

The two main components—the electrochemical conversion hardware through which the fluids are flowed (which sets the peak power capacity) and the chemical storage tanks (which set the energy capacity)—may be independently sized. The design permits larger amounts of energy to be stored at lower cost than with traditional batteries.

Progress has so far been limited in part by a lack of cheap catalysts that can speed up the generation of hydrogen and oxygen. The DTU researchers created a device to harvest the energy from part of the solar spectrum and used it to power the conversion of single hydrogen ions into hydrogen gas.

Using an inexpensive polymer called melamine, researchers from UC Berkeley, Texas A&M and Stanford have created a cheap, easy and energy-efficient way to capture carbon dioxide from smokestacks. The low cost of porous melamine means that the material could be deployed widely.

The process uses relatively little energy and a relatively cheap material—iron sulfide with a trace amount of molybdenum as an additive. Herein, we demonstrate a sulfur looping scheme in a one-reactor system using a low-cost and environmentally safe iron-based sulfur carrier. —Jangam et al.

Researchers at the Université de Sherbrooke, Canada, with colleagues at the Université de Toulouse, France, have developed a process for the direct production of levulinates from cheap residual lignocellulosic biomass using an affordable homogeneous catalyst. A paper on their work is published in Fuel.
