Despite the huge strides energy storage has made, significant hurdles remain before the technology in its many guises can be claimed to have fulfilled its massive potential. E-S.n editor Andy Colthorpe assesses the key successes and ongoing challenges for this indispensable part of the future power system.
BloombergNEF has predicted an exponential multiplying of non-pumped hydro energy storage installations around the world, culminating in nearly 3,000GWh of deployments by 2040.
The company’s partner in Japan, Next Energy & Resources, has predicted that the growth of home solar - and now energy storage - systems will help provide the impetus for new business models, including the growth of third-party ownership.
Thanks to “innovative business models” and the combination of PV with batteries, Japan’s “solar boom” is far from over, market expert Izumi Kaizuka of RTS PV has said.
This year has already seen “significant acceleration” of activity in the global grid-connected energy storage market, with 4.3GW expected to be deployed this year, analysis firm IHS Markit has said.
We asked Dr Rahul Walawalkar, executive director of the India Energy Storage Alliance, three simple questions to illuminate what was achieved in 2018 and what held the market back, if anything. We also look ahead to this year and what we might expect to see going forward.
What has driven the recent boom in Germany's household energy storage installation figures? What value do customers expect when adding a storage system to their homes? And more importantly, what are energy storage providers doing to sustain and accelerate growth, which can eventually unlock a true mass market? Florian Mayr of Apricum takes a closer look.
The market for power conversion systems (PCS) used in energy storage is becoming “increasingly crowded” with competitors, while the diverse field of players will contribute to “rapid technological innovations and price reductions”, Navigant Research has said.
In the second part of our interview with Valts Grintals, analyst at Delta-ee we discuss why behind-the-meter energy storage, including commercial and industrial (C&I) and residential installations, contributed so much to the market’s recent success.
The UK’s transmission system operator National Grid’s redesigned Capacity Market targets around 50GW of reserves up to 2023 and could be an early step towards longer duration energy storage batteries.
Halfway through 2018 and large-scale battery storage in the UK has reached over 450MW installed capacity, with around 250MW being completed this year alone. This is made up of projects bigger than 1MW, including larger behind the meter projects that have begun to emerge.
Commercial and industrial (C&I) energy storage in Europe, described by one analyst as “beginning to take off”, is the “most exciting” segment of the market at the moment, according to BYD’s global service partner.
At this year's Intersolar Europe/ees Europe event, Ron Shen of GoodWe spoke on camera with our sister site PV Tech. The China headquartered inverter manufacturer, which has recently diversified into adding capabilities such as module-level monitoring and optimisation to its range and launched products specifically aimed at the growing market for bi-facial (two-sided) solar panels, sees energy storage as a critical component of a successful future PV business.
Europe’s installed base of electrical energy storage leaped by almost 50% during 2017 but perhaps the bigger takeaway is the growing share of battery systems installed behind-the-meter, an analyst has said.
As early as next year, demand for energy storage in consumer electronics could be overtaken by markets for electric mobility and stationary energy storage, Lux Research has forecast.
