Since the publication of the second edition of our E-Storage Updater, the global buzz in the energy storage sector has been predominantly focused on opportunities in electric vehicles (EVs) and the application of blockchain technology.
As public policy surrounding EVs starts to emerge, so too is commercial activity increasing. Most recently Sony has moved into the EV sector, joining Panasonic, LG Chem and BYD. Vehicle manufacturers are also increasingly turning to EVs; in the last month Daimler has signed a supply agreement with North Star Battery, and Volkswagen has put vehicle electrification at the heart of its 2025 strategy.
As distributed energy and energy storage looks set to disrupt the traditional utility business model, researchers globally are considering how blockchain technology can revolutionise these models. A new, fast and computer-automated way of undertaking energy transactions, combined with high penetrations of distributed generation and storage technology has the potential to revolutionise power markets.
The background context continues to be the diversification into storage by utilities, automobile manufacturers and oil and gas companies. Innogy SE, the renewable energy subsidiary of German utility RWE, which signed a share purchase agreement to takeover the solar and energy storage business of Belectric, is an example of this. MOUs have also been signed between ENGIE and investment adviser SUSI Partners (to promote grid-scale power storage) and between Enel and Chinese automobile and battery manufacturer, BYD Ltd.
In the UK, the market for energy storage is seen as having significant potential; the Department of Energy and Climate Change (DECC), now part of the newly-created Department for Business, Energy & Industrial Strategy), had suggested that there is scope for growth of storage of up to 20 GW by 2050. In August, National Grid announced the results of the first Enhanced Frequency Response tender. As interest in the UK market grows, Norton Rose Fulbright and SgurrEnergy have joined forces to review some of the key legal and technical issues relating to the development of electrical energy storage alongside existing and future renewable energy projects in the UK. This article, Scaling up energy storage in the UK, discusses the key revenue streams for those considering investing in or funding energy storage in the UK. We also address planning and financing issues, together with some of the legal issues that co-locating energy storage alongside renewable generation can pose. Current interest in this sector is primarily in lithium-ion batteries, but a number of existing and developing technologies offer competition and the promise of lower costs. SgurrEnergy provides a summary of the application of different storage technologies and some of the key revenue streams.
We hope this article and third edition of our E-Storage Updater are of interest to you too, and look forward to receiving any comments, suggestions or queries you may have.

Utilities harnessing bitcoin technology for electricity revolution
Utilities are changing their business model: independent wind and solar farms are feeding into power grids in short, sometimes unpredictable intervals that require transaction systems to be more nimble and decentralized. As a result, researchers and utilities are working to adapt the cloud-based ledger system called blockchain used to track bitcoins as a replacement for slower administrative systems that require constant human input and multiple spreadsheets. Once set up, blockchain automatically records individual actions within a system, formats them, and stores the results in a secure online listing available to anyone anywhere with access. Utilities including RWE AG in Germany and Fortum OYJ in Finland are actively looking into blockchain technologies.
Update to DNV GL guidance
DNV GL officially published the GRIDSTOR Recommended Practice on Grid-Connected Energy Storage Systems (DNVGL-RP-0043) in December 2015.

Massachusetts is on track to become the third state in the U.S. to pass targets for energy storage procurement. The legislature passed an omnibus energy bill in September 2016, which, if signed by the governor, would instruct the Department of Energy Resources to set a storage target for 2020 if they deem it to be necessary. Shortly afterwards a new report concluded that 600 megawatts of storage capacity installed by 2025 would save the state’s ratepayers $800 million in system costs.
The politics of lithium
Chile contained 54 per cent of known lithium reserves in the world as of 2015, with lithium brines in salt flats of its Atacama Desert. However Argentina – also a hotspot for lithium brines – is acting faster to capitalise on the growing demand. Following the Chilean government’s move to withdraw Soc Quimica & Minera de Chile’s (SQM) licence to exploit the nation’s vast deposits, reports are that the company chose to invest in a lithium project in neighbouring Argentina.
