Anode-less redox flow batteries capable of fast cycling
Researchers in the US have demonstrated that replacing the planar lithium anode in a redox mediated lithium-sulfur redox flow battery with a high surface area scaffold enables 10 times faster cycling, up to 10 mA cm−2, without short circuit or voltage instability.
Ascent Solar hits 15.2% efficiency in production trials for CIGS cell
Ascent Solar has achieved a 15.2% efficiency for a copper indium gallium diselenide (CIGS) cell in production trials by replacing cadmium sulfide with a new material in the manufacturing process.

The Hydrogen Stream: North African hydrogen development stokes concerns
French researchers have identified a number of potential social issues that may arise as North Africa develops its significant hydrogen potential, while the European Commission has released the details of its pilot auction for European renewable hydrogen production.
Solar for water deionization
Scientists in Canada have combined PV power generation with water purification based on capacitive deionization (CDI), which is claimed to have low operational cost, enhanced energy efficiency, and less water rejection than conventional purification techniques. The solar-powered system prototype is able to produce more water than a conventional CDI system on a sunny day.
