At an energy storage fair in Dusseldorf, researchers will present a ceramic high-temperature battery. Storage costs using sodium-nickel-chloride battery cells are said to be 50% lower than those of lithium-ion.

The German car giant has created Elli, a subsidiary that will provide green power and charging solutions for the EV sector. Volkswagen – still haunted by the diesel emissions scandal – says it wants to make mobility sustainable.

After months of preliminary work, the time has come: With its PV+home storage network, sonnen GmbH has received prequalification from TenneT to participate in Germany’s primary control energy market. While it is currently allowed to deliver 1 MW, the goal is to supply 100 MW.

Greenpeace operates a renewables-powered electricity retailer in Germany, in a Hamburg-based operation. It has proposed purchasing giant utility RWE’s coal power plants and replace them with 8.2 GW of wind and solar power plants. Approximately €7 billion will be invested in the new facilities, which could be built without subsidies – Greenpeace Energy claims.

A team of researchers from Germany’s Martin Luther University Halle Wittenberg has developed a new approach to perovskite cell production, which they say could result in better stability and longer lifetimes. The team also made detailed observation of the perovskite’s formation and decay, which could help to inform further research into high performance solar cells.

According to the German solar trade association, BSW-Solar the number of energy storage systems in Germany is set to double in two years. Already, politicians recognize the increasing relevance storage has, in light of the progressing energy transition.

At US$518.4 million, the quarterly turnover of the South Korean-German manufacturer was down 10.3% year-on-year, while its net result swung from a profit of $18.7 million in the second quarter of 2017, to a loss of $41.3 million in the latest quarter. Despite this, the outlook for full fiscal 2018 remains unchanged.

Green Investment Group, Macquarie Capital’s global green investment platform, has announced the acquisition of a significant solar development portfolio from German-headquartered EPC Conergy. The acquisition will see 88 solar experts join the GIG team.

The predicted fall in global PV module prices appears to have already begun, with PVInsights and EnergyTrend reporting average prices in the $0.27-$0.37/W range.

Researchers from Helmholtz-Zentrum Berlin (HZB) and Oxford PV have presented a new record perovskite tandem solar cell, with a 25.2% conversion efficiency, independently verified by Fraunhofer ISE. Bernd Stannowski, from HZB presented the results this week at the World Conference on Photovoltaic Energy Conversion (WCPEC-7) in Hawaii.
