On a visit to heat battery maker Sunamp’s office, Scotland’s energy minister Fergus Ewing outlined aims to collaborate with his counterparts in England, Wales and Northern Ireland on nationwide storage strategy, while Sunamp CEO Andrew Bissel says greater understanding of heat source batteries is needed for the technology to be included.

News in brief: Australia gets its largest battery storage system to date, Tesla man persuaded to go back to Sonnenbatterie and Gildemeister installs PV-linked flow battery systems in Czech Republic.

GE has provided its largest storage system to date, a 30MW for Coachella energy Storage Partners (CESP).

Following the announcement of a ‘virtual power plant’ pilot in Australia, Sunverge energy storage systems have been selected for another trial project to test the capabilities of customer-sited storage, this time in the US.

Construction has begun on what is claimed to be the world’s first modular large-scale battery storage system, a 5MW device at a research university in Aachen, Germany.

Australia’s Renewable Energy Agency (ARENA) released a hefty report on global energy storage and how it relates back to the domestic situation last month. Tom Kenning investigated one of the report’s main conclusions – that the value for energy storage in Australia, initially at least, will most likely be found behind-the-meter.

Effective ways of assigning economic value to services provided by aggregated storage systems must be found to progress the use of such technology, according to a technical consultant involved in a recent report assessing Australia’s energy storage landscape.

India’s Ministry of New and Renewable Energy (MNRE) has invited expressions of interest (EOI) for energy storage demonstration projects to integrate renewables, recognising that the technology “has the potential to become highly attractive for both grid-connected and off-grid renewable energy applications”.

The man who will host the UK’s first Tesla Powerwall in his home has said the British residential energy storage industry needs to avoid “false starts” which could result in “lots of inappropriately installed systems”.

Renewables policy in the UK is in a state of flux, to say the least. PV Tech Storage’s Andy Colthorpe spoke to UK solar industry veteran Ray Noble about how and why this may be the perfect time for storage to shine in British households.
