Distributed Storage

The Berlin Energy Transition Dialogue 2022 event has shown the centrality of renewables and green hydrogen in the world’s future energy landscape. pv magazine spoke with the General Director of the International Renewable Energy Agency, Francesco La Camera, about the difficulties of creating a hydrogen economy in the absence of demand. According to him, public support and policies will be crucial to overcoming this challenge.

Researchers in Spain have assembled a 10kW/20kWh vanadium redox flow demonstrator that paves the way for a 50kW battery.

A new deal between Fortescue Future Industries and E.ON will see the Australian company deliver 5 million tons of green hydrogen to Germany, the Netherlands, and multiple cities in Europe by 2030.

Homeowners who participate in a new Enphase pilot project will connect their home batteries to the US grid, sharing energy through Green Mountain Power’s distribution system in exchange for financial incentives.

The International Renewable Energy Agency’s latest global outlook has spelled out just how ‘woefully’ far the world is from capping temperature rises at 1.5C, and lamented: ‘The stimulus and recovery efforts associated with the pandemic have also proved a missed opportunity.’

Western Australian company Global Energy Ventures has had several permissions granted for its 2.8GW green hydrogen export project on the Tiwi Islands, off the coast of the Northern Territory, including potentially increasing the acreage for its proposed solar farm.

German scientists have tried to determine whether a PV system linked to a small electrolyzer, a fuel cell, and lithium-ion batteries could fully power a grid-connected household. Their new proposal consists of a 6.8kW PV array, a 5kW electrolyzer, a 1.24kW fuel cell system, and battery storage.

The US manufacturer has expanded the battery capacity options for its SunVault Storage product, up to 26 kWh and 52 kWh configurations.

The autonomous system is designed for small companies that produce milk, juice, beverages, or food products, it and can reach four degrees Celsius in three hours with an external temperature of 30 degrees.

Researchers from The University of Queensland have developed a new nanotechnology that purportedly more than doubles the lifespan of high-voltage lithium-ion batteries, paving the way for higher density and lower-cost energy storage solutions.
