The ESN Innovation & Life-cycle Seminar - Monday 11 September 2017 - London 

For those of you who attended click here for the presentations. 

The seminar addressed the wider issues surrounding the use and application of electricity storage.  Earlier in the year, we held a special seminar on risks and safety with energy storage, and this week, we invited members and others to a seminar to discuss innovation and the life cycle of energy storage systems to build on the ideas identified in our previous discussions.  We are all aware of how projects often have an iceberg appearance:  on the surface, relatively small, simple and possibly even elegant, but underneath there is much more to be considered. The seminar was well attended, and the scene was set by Seemat Yusuf of BEIS with an update on the Smart Systems and Flexibilty Plan and this led towards discussion of how storage fits into the new energy framework.

Batteries are close to the top of the agenda in the storage industry, and the battery industry has an excellent record for recycling according to Peter Stevenson of GS Yuasa.  Recycling of lead from old batteries now contributes around 50% of the total lead used in industry.  More than 98% of a lead acid battery can be recycled, compared to around 15% of zinc from zinc batteries.  Peter then went on to say that recycling rates depended very much on the collectability of scrap batteries; the difficulty of scrap processing; the price of re-cycled materials compared to primary sources and regulation.

Looking forward to the growing use of lithium ion technology, Peter found it difficult to have a clear picture of re-cycling levels, as the present scale of lithium ion business is too small and as lithium-ion technology is changing very rapidly to make viable predictions. The recycling of materials and the  prospect of second life applications would have a major impact on future costs and sustainability of batteries.  The lead acid business model is a good starting point for setting levels of recycling, but Peter suggested that economic drivers would be more of an incentive than regulations. 

Peter’s presentation was followed by Ian Atkinson of DEFRA who presented a brief summary of the Batteries Directive and the corresponding UK regulations.  The directive and the regulations were drafted several years ago, and with substantial change in the market, the interpretation of the regulations within the context of today’s scenario is complex.  Revisions were expected to the directives from the EC this summer, but the due date has passed.  The directives have an impact on the end of life issues for batteries, and with different procedures for different types of batteries (automotive, industrial and portable) delegates were concerned with how the regulations would be applied, particularly in the context of the current interest for large scale batteries for frequency response services.  We also identified the uncertainty in return and recycling of time expired batteries which have been re-purposed in second life applications.

We continued the discussion on the energy storage life cycle with an examination of the parameters of through life cost.  Fernando Morales of Highview Power proposed the use of Stanford University’s metric “Energy stored on invested (ESOI)” which is the ratio of  energy stored to their lifetime embodied energy requirements.  This metric allows comparison between technology types such as electrochemical and mechanical devices, and between different types within each category.

He went on to explain the need to also consider lifetime CO2 reporting for storage.  Aazzum Yassir from S&C pointed out that storage projects had to include warranties, complete system monitoring, annual maintenance, spares and support and future flexibility for new applications.

We were very pleased that the discussion worked to develop our ideas for promoting energy storage as a sustainable and environmentally friendly industry.  We will be following up contacts from members and our academic friends to continue the analysis of the whole energy storage life cycle and work with our colleagues in industry, government and the media to ensure that our industry extols best practice in this area.
 
The second topic for the day was Innovation, and we heard about the approaches of a network operator, a small scale storage provider, a large scale storage provider as well as guidance from BEIS and OFGEM.  UKPN, represented by Ian Cameron illustrated UKPN’s approach to innovation and in particular to energy storage, with a rapid but still detailed review of a full programme.  UKPN wanted to see energy storage incorporated wherever it would bring benefit, and Ian encouraged members to contact the UKPN team with proposals.  Moixa Energy has secured many projects funded through Innovate UK as well as the OFGEM supported programmes with the DNO, and Simon Daniel, their CEO, explained how their business took innovative ideas, starting with hardware, but moving into systems,  His view was that system control would be the predominant technology influencing their business.  On the larger side of our industry, Marek Kubik from AES Energy Storage proposed that the storage industry of the future would be based on an open architecture basis, and innovation would be driven into finding new market structures.

Sally Fenton, who is well known to the members of the ESN, reviewed the current proposals for innovation funding from BEIS, and in particular the funding targeted at energy storage.  Neil Copeland of OFGEM explained the role of the OFGEM programs for network innovation, the NIA, the NIC and the IRM – the Innovation Roll out Mechanism.

The current expansion in deployment of storage has been driven mostly by technology installations with short-duration energy storage capacity. The Electricity Storage Network seminar held at the Institution of Mechanical Engineers in London, on May 4th considered the development of Longer Duration Storage in order to bring attention to all aspects of electricity storage within  the energy industry. 

 

Storage assets are beginning to be installed now, and commercial and regulatory frameworks being considered, that are likely to persist into the 2020s. It is therefore important that these be developed with a view to longer-duration service needs. The seminar, with presentations, panel sessions, and active audience discussion, considered the volumes and timescales over which longer-duration storage may be needed; current regulatory and market arrangements for deployment of longer-duration storage; and the prospects for the future regulatory and market landscape

 

The Chairman, Anthony Price, introduced the emerging need for longer‑duration storage and the challenges ahead and posed two Questions:

 

  • ·      With a likely move to Longer Duration Storage, will the predicated “commercial and regulatory changes” anticipated by summer 2017 be fit for purpose or are they are already out of date?
  • ·      Do we need to prepare for investment in longer duration electricity storage?

 

We were fortunate to secure Professor Goran Strbac as one of our opening speakers.  His team at Imperial College, London have considerable experience and capability in scenario planning and their work confirmed  that with a high penetration of renewable generation, the network must be flexible and responsive. It was then demonstrated that the UK’s Low Carbon targets can be achieved by using storage; and significant benefits can be realised with Wind and Storage. However, if storage is merely short duration, it will not solve the overall capacity problem, the UK will need storage installations with many hours of energy storage capacity. 

 

The market pull for longer duration storage is emerging.  Ed Kenny Herbert of RES provided examples of business modelling for combined storage and renewable generation projects, where storage could improved the certainty of forecasting generation and so improve dispatchability.  Storage of several hours duration was required.  Marek Kubik of AES also proposed that, in the long run, increasing storage capacity for a project would lower costs, even when taking into account the higher costs of the initial investment.    Highview Power Systems and REDT represented by Fernando Morales and Scott McGregor respectively both commented on the need to build in future proofing the income stream of any storage asset.  Fernando commented on how projects in the USA had found themselves uneconomic as they were unable to provide services in ancillary services markets following minor rule changes.  Delegates to the meeting were absorbed the need to protect investments in storage by planning for change – and the inevitable debate and discussion on certainty of future income streams and the need for long term commitments for income against higher value for shorter term contracts was lively and informative.

 

Andrew White from  Ofgem recognised the key challenges to energy storage in the UK and explained the likely timetable for implementation of regulatory changes.  Paul Lowbridge of National Grid, speaking on the behalf of the SO, said that the SO want to see  a greater role for Energy Storage, Demand Side Management operating with wind & solar generation. They too want to see storage enjoy a level playing field with other energy sources and services. Their aim is to revise and simplify balancing services regulations and introduce appropriate and fair pricing signals and mechanisms, whilst promoting the stacking of ancillary and balancing services.

 

Sotiris Georgiopoulos of UKPN provided a preview of the tender process for “flexible products” (including services from energy storage) and an industry-wide consultation will begin in May 2017.  The commercial side was not forgotten and Rory McCarthy of  Origami Energy brought the themes together by addressing the needs for co-ordination of services.

 

There was much discussion from the floor and the salient points included…

 

  •       Li-ion appears to be dominating for high-power, short duration ancillary services. How can other technologies, (NAS, Cu-Zn, compressed-air, liquid-air, flow cells and hybrids break through?
  •       Investors should be educated as to the potentially lucrative revenue streams from energy storage.
  •       Longer contracts are preferable to give investors more appetite, certainty and investment protection.
  •       More clarity from government. Policy and Mechanisms should address barriers and enable storage.
  •       Consistency required regarding trading conditions, (generator definition/ownership, CfDs, ROCs, PPA).
  •       It is commercially desirable to be able to stack ancillary and balancing services.
  •       BEIS, National Grid and Ofgem have acknowledged all the above and are working towards solutions.

 

The Electricity Storage Network (ESN) is dedicated to electricity storage with eight years of policy and regulatory work. It is keen to promote all technologies, scales and durations of electricity storage. We enjoyed a high level of discussion in an open and friendly format.  Summarising the meeting on behalf of the ESN, Zoltan Zavody  recognised that BEIS/Nat-Grid/Ofgem have acknowledged the key challenges and are in the process of addressing them. Zoltan confirmed that longer duration storage is an important part of the storage agenda and the ESN looks forward to working more with our members and other interested stakeholders as we move into the next big phase for storage!

ESN Annual Symposium:

Good Storage, Better Storage, Excellent Discussion

The ESN held its eighth Annual Symposium, “Good Storage, Better Storage,” on 25th January 2017.  We were pleased to receive over a hundred delegates, including developers, manufacturers, suppliers, network companies, regulators, and a keynote from Government.  We are grateful to all our sponsors for their support and to our partners who helped us with publicity, and to our joint chairmen Ian Arbon of Engineered Solutions, and Mike Davies of Eider Reserve Power.

Over the course of a packed day of presentations, responses, and panel debates, a number of points and themes emerged.  These are summarised below.

Policy and Regulation

Government is committed to publication of a “Smart Systems Plan in spring 2017, “outlining the actions it will take to remove barriers for smart solutions and provide a longer term direction for the transition to a smart energy system.”  The general industry response, including from major players such as RES, AES, and S&C, was that the “legacy barriers” to market deployment need to be removed quickly; there is no need for further reviews.  The plan should contain milestones for action.

Ownership of storage by the electricity networks was raised.  – What if services providers in the market did not come forward with storage solutions?  UKPN stressed they would always seek the lowest cost solution for the customer, using market solutions wherever feasible.  The panel suggested that the priority be to ensure that the market is enabled to provide such solutions. 

Scale and Society

The session on “A Society Powered by Storage,” set out the trends and prospects for various scales of electricity storage, from household to transport to distribution scale to transmission “grid” scale.

According to Connected Energy Storage, there are some 60,000 Electric Vehicles on the roads of Britain already, with a capacity of some 1.5GW, accounting for the bulk of our electricity storage.  However, the question was raised whether in, the highly competitive environment of car sales, it was realistic to expect vehicle manufacturers to incorporate expensive grid integration equipment.  Rather, Moixa suggested, the market for household batteries is soon to take off, with massive household appeal and ability to deploy far more rapidly than that of large units.

On the other hand, argued RedT, larger units could operate as longer-life, multi-purpose assets with >60% utilisation rates, rather than as replaceable batteries.  This was particularly important when usage entailed not only system stability services but network asset deferral and, later on, reduction of renewables curtailment, a point made by Highview Power.

Who Pays Who Wins?

Poyry, in the session, “Who Pays Who Wins,” set out four broad applications of electricity storage: merchant service provision, network asset deferral, co-location on the grid with generation, and behind-the-meter.  Some of the potential positive and negative knock-on effects were set out, for example additional network management costs, retailer imbalance costs, and the question was raised as to whether all such “externalities” should be monetised.

In relation to the range of services required, Flexitricity highlighted the challenge not of the service itself, but of managing the state of charge of the storage facility such that it is available when needed – where is the revenue stream for maintaining the state of charge?  CER, the Commission for Energy Regulation in Ireland, set out their approach to the regulatory framework for the provision of services and providing adequate incentives, but highlighted the difficulty of supporting long-term service provision and availability contracts in the context of the EU Balancing Code.

Good Services, Better Services

In the afternoon session on “Good Services, Better Services,” National Grid set out their proposed “whole-system” approach to the procurement of services as a more independent System Operator.  As well as outlining the principles for developing some simpler products, National Grid suggested there would not be another EFR tender, but rather EFR would be incorporated into a new FR tender in July 2017.

TLT, having been involved in some 40% of EFR tenders, in their talk “From Spreadsheet to Deployment” set out the legal and contractual considerations for developing a storage project, including a focus on co-located and behind-the-meter configurations.  EDF Renewables gave an account of the drivers for their 49MW West Burton EFR project, where co-location with existing generation assets was one of the keys to the success of their EFR tender bid.  Kiwi Power rounded off the session on services with an account of how revenues from various services compared, noting that the potential for annual revenue ranged from £5,000/MW under the Capacity Market to >£100,000/MW for frequency markets, albeit the risk profiles and utilisation regimes differ.

UK Industry & Innovation, Global Market

Turning focus further afield, the European Association for the Storage of Energy (EASE) outlined the latest provisions for energy storage as set out in the Winter Package.  EASE suggested the UK would continue to adhere to EU policy requirements on energy, regardless of Brexit.  EASE also flagged the availability of some 2 billion Euros for storage projects, for which post-Brexit eligibility seems less clear.  AES, a company with global reach, set out the need for robust, credible, safe projects and project specifications that are not assessed on price alone, not least to protect the reputation of the storage industry.  Returning to the initial theme of the day, AES stressed the need for removal of market barriers domestically as part of the strategy for UK industry to be on the front foot beyond our shores.

To finish the day with hot news, BEIS arrived to announce funding support for innovation in energy storage, in particular: a £9M competition for reducing the cost of energy storage; and £600k for a first-of-a-kind, large-scale storage facility.  Questions arose around support for pre-commercial deployment of proven technologies.

Conclusion

The topics of discussion covered:

  • the need for quick solutions, notably removal of market barriers
  • the need to facilitate various scales of storage and prepare for the societal implications of each
  • the flow of value streams and the importance of aligning these
  • the need to keep an eye on European regulation and global markets
  • innovation support, with appropriate health and safety regulations

These are among the key topics the areas the ESN will pursue over the course of 2017.
