A group of researchers has identified a multispecies bacterial community that could reportedly increase the efficiency of hydrogen generation via microbial metabolism. The proposed hydrogen system achieved a more than double production rate compared to common biological hydrogen production technologies.

Conceived by a group of scientists in Australia, the novel online tool can be modified for different regulatory environments. The program’s user interface asks for seven input files with a resolution of 30 minutes.

Fluvius, Belgium’s electricity grid operator, says it will compensate residential PV systems at €10.60 ($11.49) per kVa if they are not reconnected within 30 working days after a curtailment event.

Autarco has developed a three-phase hybrid inverter line, featuring 8 kW, 9.6 kW, 12.8 kW, and 16 kW versions and up to four independent maximum power point (MPP) trackers, along with a European efficiency rating of 97.5%.

Clickcon has launched an online tool to design solar carports and shades. The tool uses the German company’s mounting systems for the designed projects.

Wevo Energy becomes a subsidiary of SolarEdge, and together the companies plan to integrate the Wevo’s software solution into the SolarEdge ONE energy optimization system for the commercial and industrial (C&I) segment.

The Department of Mineral Resources and Energy (DMRE) of South Africa has opened the third bid window for its Battery Energy Storage IPP Procurement Programme (BESIPPPP), which is procuring a total of 1,744 MW of four-hour battery storage systems. It has also announced the final winner from the first window.

The US Department of Energy’s National Renewable Energy Laboratory (NREL) has released a cost-estimation tool for new closed-loop pumped storage hydropower (PSH) plants in the United States. The tool allows operators to select from a range of system characteristics and account for factors such as local geology, labor rates and inflation.

A new report from the International Energy Agency’s Photovoltaic Power Systems Programme (IEA-PVPS) looks at success factors required to take vehicle integrated photovoltaics (VIPV) from niche to mainstream based on a survey of 110 experts in the topic of transport and PV.

Scientists have analyzed what factors affect the emergence of solar associations and cooperatives in Germany. Applying the organizational ecology theory, they found a collective solar initiative in a given district may likely lead to creation of similar experiences in the same district.
