Solar Media’s Energy Storage Summit took place at the end of February and was attended by around 350 delegates and stakeholders, looking at energy storage markets in the UK and beyond. Collected here are seven interviews with leading figures at the event spanning utility-scale, commercial and residential energy storage.

Arguing that energy storage is “critical to ensuring a resilient, reliable, cost-effective and sustainable grid”, the Energy Storage Association joined with 52 other organisations to plead the place of storage in the Trump administration’s infrastructure priorities.

Axion Power International, focusing on “hybrid battery technology” that combines lead acid with the properties of carbon-based supercapacitors, has warned that it is in financial trouble after failed attempts to commercialise its devices.

China-headquartered BYD has launched the latest iteration of its B-Box battery energy storage systems, including a high voltage model, into the European market.

To date, Primary Control Reserve (PCR) has dominated the energy storage debate in Germany with more than 100MW of battery storage installed in 2016 alone specifically for participating in the PCR market. At the same time, with close to 25,000 systems sold in 2016, residential storage has been stealing the limelight in the behind-the-meter segment. Julian Jansen of Delta-ee looks at how his team expects the commercial and industrial (C&I) segment to start catching up.

The UK’s energy regulator has taken what appears to be an encouraging viewpoint on “double charging” of energy storage, clarifying the definition of the technology’s role in the grid, according to one expert view.

California-headquartered grid-scale electrical energy storage company Primus Power has secured US$32 million in equity financing from a range of investors including a well-known Saudi family, to help accelerate its EnergyPod 2 storage system.

Solarwatt has unveiled the latest evolution of its MyReseve system, a fully modular storage system that can be customised to suit the demands of any application.

Each battery storage system is a potential source of danger. An ingenious battery management system as well as high-quality cells are the key to a safe operation. For this you need a lot of know-how. Dr Olaf Wollersheim of Solarwatt talks through some of the main topics and solutions.

Queensland’s workplace regulator, the Electrical Safety Office (ESO), has revoked its recommendation that all home energy storage battery units should be installed separately from households in an external enclosure.
