The Hydrogen Stream: Airbus plans flight test with direct combustion engine fueled by hydrogen

Elsewhere, Chinese researchers have synthesized ultrafine Pd100-xCux nanodot-modified TiO2 photocatalysts that display optimized energy barrier for interfacial hydrogen desertion, which reportedly exhibits excellent H2-evolution activity and stability, and Mitsubishi Heavy Industries has presented its plans to establish the Takasago Hydrogen Park, calling it the world’s first center for validation of hydrogen-related technologies, from hydrogen production to power generation.

Bringing the noise for better solar cell efficiency

An international team of scientists developed a technique to isolate individual sources of electrical ‘noise’ within a solar cell. Comparing the technique to being able to pick out a single voice within a 200-person choir, they say the technique will help to improve understanding of where efficiency losses occur within a cell, and effective ways to mitigate them.

Redox flow battery powered by perovskite solar cells

An international team has developed an integrated solar flow battery which has been suggested as ideal for off-grid locations. The device, which combines energy conversion and storage in one unit, can be used for lighting and recharging cell phones.
