While solar and energy storage are not inextricably linked, at least not yet, storage helps households make the most of their solar power and one day could help grid networks make their final leap of faith. In the second of two blogs from the Energy Storage Europe conference and exhibition in Düsseldorf last week, PV Tech Storage talks to experts and industry figures as they tackled some of the biggest issues facing storage and renewable energy.

Andy Colthorpe met Enphase vice president of products and strategic initiatives, Raghu Belur at PV Expo in Tokyo last week. The company’s co-founder explained why he felt Enphase will offer the market a reinvention of behind the meter home energy storage, specific criteria for differentiating energy storage products and what made Japanese battery vendor Eliiy Power the right fit for the Energy Management System.
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.
It is sometimes said that as of today there is no business case which delivers economic viability for decentralised residential battery storage systems owned by private end customers- without subsidy programmes- or they propose other solutions which offer higher benefits. Despite the discussion, the market already offers a variety of storage solutions which seem to be well accepted by the end-customer. Volker Wachenfeld of SMA explains the contrast.
For decades Australia has been at the forefront in deploying renewable energy, coupled with energy storage solutions, in off grid and fringe of grid areas across remote Australia. Many communities have transitioned away from polluting and expensive diesel generators and now use reliable and sustainable renewable energy and energy storage solutions. But it is only now that the full impact of lower energy storage costs are becoming clear, writes John Grimes of the Australian Energy Storage Council.
E.ON, the German utility giant with 61GW of generation assets, has announced plans to split its business in two. The company will stake its future on renewables in a major restructuring, spinning off its conventional power generation business, in part as a response to the growth in distributed generation. Cosmin Laslau of Lux Research digs deeper.
Energy security is a growing concern for economies across the world with electricity outages currently costing economies billions of dollars annually, driving electricity prices up. The US experienced nearly 700 power outages caused by severe weather between 2003 and 2012, costing the country up to US$70 billion annually.
Will the Indian battery market scenario witness a major change? As the power supply in the country continues to be unreliable, the role of batteries has to change from being an emergency back-up solution to a long time power/energy storage solution.
Just 3–4% of electricity generated by utilities globally is stored today, according to the International Energy Agency. This is despite the fact that storage can help overcome the energy ‘trilemma’ of curbing rising energy prices, the need to ensure the security of supply and creating a low carbon economy. So, what’s the hold-up? Taking the UK as his starting point but with lessons transferrable to other regions, Roger Lin of NEC Energy Solutions explains and counters some of the myths that stand in its way.
