A spokesman for Solar Frontier has said that a retrofit market for up to half a million home energy storage systems could open up in Japan from the year 2019, as agreements made under a subsidy scheme for solar in existence before the current feed-in tariff begin to reach the end of their terms.

Volker Wachenfeld of SMA explores some technical and policy factors driving growing use cases for refurbishing home PV systems to add energy storage, and the markets where this is already gaining traction as an idea.

Secure financing for energy storage is likely to be the main driver for its deployment, the chief of the UK’s biggest solar developer has said, echoing views given to Energy Storage News by analysis firm Lux Research.

News in brief: A battery park in Germany will be capable of restarting the local grid in the event of a blackout, a public square in Haiti will be lit at night with solar energy, and a revived Solarmax will target its new range of storage and inverter solutions at several European markets this year.

Research firm IHS recently reported that as of the end of 2015, there was a global pipeline of 1.6GW of battery or flywheel-based grid storage projects in place. Andy Colthorpe spoke to principal analyst Marianne Boust, who explained why last year truly saw a “change in stakeholder mentality” in favour of energy storage and why 2016 will be another record-breaking year.

Workable alternatives to utility power involving energy storage are beginning to emerge with new and innovative business models, according to an investment advisor who worked on Younicos’ recent US$50 million “land grab”.

Building control manufacturer Johnson Controls, a recent entrant to the energy storage market, has announced a US$20 billion takeover of security and fire protection firm Tyco as it looks to consolidate its offering in the smart building sector.

A joint statement on economic and social cooperation between the governments of India and France has “noted the important role of energy storage to promote renewable energies”.

Although Britain’s government has cut support for renewable energy severely in the past few months, controversially claiming a need to balance the transition away from fossil fuels against the cost to consumers, energy storage may face less of a challenge at the top level, according speakers at a conference in London.

Misconceptions over the true value of energy storage are developing because of a “narrow focus” on the initial costs of the technology, a report has concluded.
