Japan-headquartered NGK Insulators is the manufacturer of the NAS sodium sulfur battery, used in grid-scale energy storage systems around the world.
While Brexit – the impending departure of the UK from the European Union – looms, bringing uncertainty into the country’s economy and international relationships, the role energy storage will play in a decentralised, low(er) carbon and more flexible energy system at least seems a little more assured than it did before.
Increasing Li-ion demand will help to continue to lower energy storage costs, but also brings up an important issue: what should be done with the batteries after they are used in vehicles? Chris Robinson of Lux Research weighs up the pros and cons of recycling versus repurposing for second-life use.
To date, the vast majority of the entries into the energy storage market have depended on lithium-based battery chemistry, but, the idea that lithium-ion is the technological and economic front-runner in the stationary storage space is a myth that is in dire need of de-bunking, claims Ron Van Dell.
SPONSORED: The integration of smart microgrids with existing power infrastructure and renewable generation offers myriad opportunities, as power systems developer Nidec explains.
Microgrids—distributed systems of localised generation, distribution network and load—are being increasingly deployed particularly in rural areas of emerging and under-developed countries to achieve energy access. However, a “fragmented and unorganised” sector still faces significant challenges, writes Harsh Thacker.
Every year sees energy storage build on the success of the preceding one, it seems, and this year we were able to carry insights and opinions from some of the best placed participants and observers. Here’s our picks for the content most representative of the year it’s been, as well as the 10 most read news stories on the site.
There is no shortage of vendors looking to offer batteries and energy storage for the residential market. Greg Wolfson of Enphase discusses AC- and DC- coupling of batteries and why his company felt AC is the way to go.
By combining PV with a storage solution, homeowners gain from a variety of possibilities to increase self-consumption, improve system profitability, and get backup power. However, it is important to know how to select the right kind of storage solution. Lior Handelsman of SolarEdge discusses some of the main factors involved.
New value propositions which will radically change the way energy is generated and used by end-customers are already accelerating energy storage market growth. Julian Jansen of Delta-ee takes a look at three distinctive types of business model which are taking shape.
