Ensuring battery systems used in conjunction with solar perform safely and optimally is essential in the continued roll-out of storage technology. Robert Puto and Gerhard Klein of TÜV SÜD examine independent technical assessments that must be undertaken before a storage system is built.

The fire unit at global multinational engineering firm Honeywell made its first move into lithium-ion safety in recognition of battery storage’s “huge potential” for decarbonisation and to help the world move “in a more energy efficient way”, the company has said.

HOMER Energy announced that it has been bought by global safety certification company UL, following the completion of the aquisition on 16 December.

The second draft of the US National Fire Protection Association (NFPA) energy storage system guidance on fire hazards and safe installation best practices for stakeholders has been published.

As it prepares to break ground on a ‘Gigafactory’, energy storage system provider Tesvolt has said that gaining certification across diverse regions remains the biggest challenge in forming strategy today.

Shanghai-headquartered energy storage system maker Pylontech has become the first company to receive certification from TUV Rheinland that its lithium battery storage devices are suitable for use in Germany.

A new solar-plus-storage division is to be launched by DNV GL, the expert advisory group and certification body announced at Intersolar Europe on Wednesday.

UK PV installer Martin Cotterell argues that the renewables industry needs something in place to make sure that battery systems are sold appropriately; for instance, there is the potential for customers to get charged extra for a battery ‘add-on’ that doesn’t really give them a whole lot of benefit.

Grid storage and distributed energy technologies overseen by the Advanced Research Projects Agency – Energy (ARPA-E) in the US will be accredited by technical advisory service DNV GL for the next four years.

TÜV SÜD has developed a certificate for renewable energy storage systems (RESS), which the testing house claims will “provide reliable information on the safety, performance and service life of stationary energy storage systems”.
