German scientists have developed a novel hydrogen storage method that relies on nanostructures – tiny nanoparticles made of the precious metal palladium – instead of high pressure and lower temperatures.

The solar roof was developed in collaboration with the Fraunhofer Institute for Solar Energy Systems.

Reliance Industries said its solar unit will buy UK-based sodium-ion battery technology provider Faradion for GBP100 million (AUD$187 million) including debt, as the Indian conglomerate pushes forward with its ambitious plan to move into the renewable energy industry.

Anglo-Australian multinational Rio Tinto has invested in European-based battery technology and manufacturing company Inobat Auto with the mining giant aiming to extend its operations throughout the electric vehicle battery value chain in Europe.

Developed by German researchers, the 20.9%-efficient device was built with an architecture avoiding the use of the ionic dopants or metal oxide nanoparticles that are commonly used to contact the cell, as these can be subject to secondary reactions at higher temperatures.

The device was designed by scientists in Portugal to optimise 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.

The proposed measure, which will now pass to the Council of Ministers and European Parliament for debate, would further the adoption of PV, according to SolarPower Europe, especially if the commission’s proposal it be applied to public sector structures from 2027 is adopted.

The transaction, for which Shell did not reveal the purchase price, will see the energy company pick up a U.S. project development pipeline which reportedly runs to more than 18 GW of solar generation and energy storage capacity across 26 states.

With Scottish company Smarter Grid Solutions having already seen its software deployed in the U.K., a pilot project in New York State has been a resounding success for a grid solution the NREL has predicted could unlock swathes of network capacity without the need for new power lines.

An Italian company has developed a system that can store energy from wind, solar and grid electricity by compressing and using CO2 without any emissions. The system draws CO2 from an inflatable atmospheric gas holder, stores it, and uses it to produce power again, when demand for stored energy arises.
