Standard Energy unveils vanadium-ion battery with 1% degradation

Vanadium offers unique characteristics as a battery material, as it can shed electrons without shifting from its ionic state, ensuring high cycling stability. South Korea’s Standard Energy has developed a battery with just 1% degradation after 20,000 cycles. The company has already completed 10 MWh of projects in its home market and now aims to expand internationally.

German decommissioned nuclear plant to become 800 MW/1,600 MWh battery

PreussenElektra has revealed plans to potentially develop Europe’s largest battery storage facility at the decommissioned Brokdorf nuclear power plant site in Germany, with 800 MW/1,600 MWh of capacity. The site operator now needs to secure approval to dismantle the nuclear plant.

VoltStorage unveils vanadium redox flow battery for commercial use

Germany’s VoltStorage says its containerized 50 kWh vanadium redox flow battery solution can be scaled up to 500 kWh.

From diesel to DC

For a long while, it looked as if hydrogen fuel cells would be the technology of choice for emissions-free road transport. However, truck manufacturers and freight forwarders recently turned their attention to battery-electric vehicles. This will require special charging technology and PV looks set to play an important role.

Elusive longevity

The expected lifetime of PV inverters is significantly shorter than that of modules. In many projects, inverter replacement is included in financial calculations from the start, despite the high costs. Research is being conducted into the causes of faults to develop more durable inverters and components. But plant design can already improve the lifespan of inverters in use today, reports pv magazine Germany’s Marian Willuhn.

Hydrogen to play limited role in building energy supply

How much hydrogen is actually needed? Several German research institutes have examined 40 energy scenarios for hydrogen ramp-up and found that 15 million GWh of hydrogen will be needed worldwide by 2050.
