TÜV Süd has discovered that 8% of the rooftops it examined in Germany last year are not suitable for PV deployment.

The International Energy Agency (IEA) says in a new report that only 7% of planned renewable-based hydrogen capacity is expected to go online by 2030. The report notes the need for consistent policies to support demand and prevent stranded assets.

Researchers at the Jülich Research Center in Germany have used novel photoluminescence measurements to analyze the recombination of charge carriers in perovskite solar cells. They have found that the loss of charge carriers in perovskite devices works differently from other types of PV cells.

In November 2022, Germany’s Energie Baden Württemberg and steelmaker Salzgitter Group signed one of Europe’s first power purchase agreements (PPAs) for hydrogen production. More have followed and with the European Union introducing rules to govern green hydrogen, an industry is planning for its future.

Smart Railway Technology’s new PV2Rail inverters are designed to feed directly into 16.7 Hertz (Hz) railway power grids.

Northvolt is set to secure €902 million ($986 million) of state aid to build a battery gigafactory in northern Germany, while France has been allocated €2.9 billion to ramp up production of batteries, solar panels, wind turbines and heat pumps, according to a European Commission announcement.

Elcogen and Convion have revealed test results for their new solid oxide electrolyzer, with an electrical efficiency above 85%. It could potentially facilitate the production of 39 kWh of electrical energy per kilogram of green hydrogen.

German developer BEC-Energie Consult has developed a mounting system that uses less material than conventional systems. It claims the new tech can reach 1.45 MW of output per hectare. It can also be used for ground-level agrivoltaic systems.

1Komma5°, a Hamburg-based startup, is set to roll out its products and software portfolio across the Netherlands.

German manufacturer SAX Power says the capacity of its new all-in-one battery inverter solution ranges from 5.76 kWh to 17.28 kWh. It is suitable for new PV systems, as well as retrofit projects.
