When lithium-ion’s dominance of the energy storage market begins to wane, redox flow batteries are well positioned as a strong competitor, emerging technology market research and business intelligence group IDTechEx has said.

With many climate protection advocates as well as the industry itself calling on Europe’s lawmakers to recognise the importance of energy storage, a “significant slowdown” in 2019 is expected to be countered with a more positive outlook going forwards.

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.

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.
