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

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.

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.

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.

With a new start-up and a consortium in the Netherlands, German automotive supplier Schaeffler wants to significantly reduce the costs of green hydrogen.

With a new system for floating photovoltaic power plants, engineers from Germany want to make the application cheaper, higher-yielding, and safer. The result is somewhat reminiscent of a pufferfish, which also gave the system its name.

The manufacturer has launched sodium-ion products online. Production has begun and will be easily scalable, according to the CATL chairman. Researchers have been keen to make the technology work as it offers a cheaper, more environmentally friendly alternative to lithium-ion products.

Sax Power has developed a new residential battery which it describes as a game-changer in the battery technology.

The battery system, which is aimed at increased self-consumption, can handle a maximum DC input power of 18 kW and 1000 V.

Sonnen has published test results indicating the longevity of its storage systems after extended use.
