Focus on energy storage
The energy storage industry is not a completely new industry and there have been short lived booms before.
As the battery and electric vehicle revolution gains momentum, attention is increasingly turning to the commodity supply chains required for their manufacture. Some manufacturers are looking to invest directly into cobalt and lithium mines to secure supply of crucial commodities such as cobalt and lithium. However, such investments present difficulties, both from a sustainability and ethical perspective, and also from a project and country risk perspective.
Given that approximately 65 per cent of the world’s cobalt production currently comes from the Democratic Republic of Congo (DRC), with some sources estimating that this will increase to as high as 73 per cent by 2023, the industry is heavily dependent on the DRC mining industry. The concerns about child labour issues and unsafe labour conditions in the DRC have been well documented. As a response, the London Metal Exchange proposing the introduction of responsible sourcing standards for all traded metals. The lack of access to responsibly sourced cobalt will render the negotiation of supply contracts all the more important for EV and battery manufacturers, who may wish to retain flexibility to allow them to respond to market conditions.
End users looking to invest directly in the battery supply chain will need to consider the risks associated with doing mining deals in emerging markets and how to mitigate those risks. Some of the key risks include change in law risk, foreign exchange/currency issues and local content requirements (such as the obligation to invest alongside local partners, restrictions on foreign investor ownership, requirements to develop local infrastructure and financial and social obligations to assist local communities). Recent legislative action taken by some governments in Africa, including in the DRC, has seen governments reneging on contractual stabilisation provisions and implementing new legislation which negatively impacts mining companies operating in those nations.
Mitigation options include purchasing of political risk insurance. This may be an expensive option however, and typically policies do not provide blanket cover for adverse changes of law, but rather may cover losses arising from two key areas of change in law risk. Our experience indicates that the involvement of Development Finance Institutions (DFIs) as an investor or a lender into a project can be an effective mitigation tool, helping to prevent governments from taking “investor unfriendly” action that would prejudice the interests of the DFI investor. Finally, Bilateral Investment Treaties (BITs) provide last-resort protection for investors where all other avenues of dispute resolution, political pressure or insurance have been exhausted. Investors should therefore consider structuring their investment through appropriate vehicles in order to gain the benefit of BITs.

According to Wood Mackenzie’s Global Energy Storage Outlook 2019, from 2013 to 2018, global energy storage deployment achieved a compound annual growth rate of 74 per cent worldwide. Whilst total global deployment remained relatively small at 7GW/12GWh, 6GWh was delivered in 2018 alone. It is predicted that deployment will reach 63GW/158GWh by 2024, but the compound annual growth rate will slow to 38 per cent. The USA and China are predicted to dominate, with over 54 per cent of deployment between them. Front-of-meter energy storage will also dominate, with projects moving from the ancillary services markets to longer duration applications. The popularity of renewables-plus-storage projects is expected to increase to 2024. It is estimated a total of US$14bn will be invested in energy storage technologies (excluding pumped hydro) in 2024, in a global market worth US$71bn in total system capital expenditure.
A recent report published by Bloomberg New Energy Finance on the levelized cost of energy (LCOE) suggests that lithium-ion batteries are increasingly becoming a cost-competitive alternative to natural-gas-fired power plants. The report found the benchmark LCOE for utility-scale lithium-ion batteries fell by 35 per cent to US$187, outpacing the decline seen previously for solar PV, and onshore and offshore wind. The report finds that lithium-ion batteries co-located with solar or wind projects are beginning to compete without subsidy with coal and gas-fired generation for the provision of dispatchable power. The article notes that while continuing technology improvements and increasing scale of manufacturing have continued to push down prices, these have been somewhat counterbalanced in the past year or so by a bottleneck in available supply, driven by demand from big projects in the US and South Korea.
In its research paper ‘Hydrogen in the electricity value chain,’ the DNV-GL forecasts that hydrogen produced from renewable energy sources such as wind and solar energy will become a zero-carbon economic energy carrier that can be used for long-term storage and heating applications. This is expected to be driven by three key developments: cost reductions in electrolysers, the increasing availability of low- or zero-cost electricity due to greater penetration of renewables and carbon reduction policies (such as carbon taxes and incentives for low-carbon solutions).
Moxia, a UK-based start-up, has secured £8.6m (US$11.1m) in funding from Honda to support its electric vehicle (EV) expansion, with developments expected later this year.

At a regional level, Solar Energy Corporation of India (SECI) invited bids for 200MW of grid-connected solar projects to be combined with 300MWh of battery energy storage. Based in Andhra Pradesh, the region where similar tenders were cancelled in 2017 - 18, the project will include two separate 100MW PV projects, each with 150MWh of batteries (for details see here). MP Power Management also has invited expressions of interest for 500MW of grid-scale energy storage in the state of Madhya Pradesh. This follows the release of latest figures for the state – as of January 2019, Madhya Pradesh’s total installed power capacity stood at 19,796MW, with only 3,827MW (19.3 per cent) from renewable energy sources (for details see here).
With 90 manufacturers and several gigafactories in the works, China is well positioned to cement its supremacy in EV battery production. The nation currently owns a majority of the global lithium-ion battery production market, with more than 60 per cent of global manufacturing capacity today. The key driver of China’s battery manufacturing ramp-up is a generous subsidy offered by the Chinese government solely to domestic vendors. According to reports, planned battery manufacturing capacity expansion for all battery applications and chemistry types is expected to grow more than 2.5 times by 2026.
The World Bank Group International Bank for Reconstruction and Development has approved US$300m loan that will finance its US$750m China Renewable Energy and Battery Storage Promotion project. The remaining US$450m will come from Chinese commercial Bank, Hua Xia. This follows the Group’s US$1bn investment for the acceleration of energy storage in developing countries. Meanwhile, the Global Environmental Facility and Energy Sector Management Assistance Program will provide financing for technical assistance towards regulatory reforms.
France and Germany have announced they will act in partnership on a project to increase the availability of reliable battery technology for EVs in Europe. Finance ministers confirmed that €5.6 - €6.7bn is expected to be invested, with €4bn of this coming from European private companies in the energy and automotive industries. The aim of the investment is to alleviate the “range anxiety” that has hindered the development of EVsin Europe, and bring their progress more in line with the Asian markets.
Ofgem, regulator for the British power market, is proposing an overhaul of the electricity network charges levied against all asset types under the Targeted Charging review. According to research by Aurora Energy, this new approach will favour low-efficiency gas CCGTs to the detriment of renewables schemes and undermining the economics of smart solutions like battery storage and demand response. The aim of the Targeted Charging review is to create a level-playing field as between different types of generation in the charging system. However the research suggests that the effect of this change would be to raise the network charges for embedded battery storage projects. The proposals come as the UK government proposes 15 per cent tax rise for solar and storage purchases planned to come into effect from October 1, 2019.
Portugal is planning to host an auction for 50 -100MW of dispatchable renewables in 2020, in a bid to attract the best, most innovative technologies in energy storage. This move has closely followed appeals by experts to “urgently” move towards storage technologies in order to ease the annual surplus of 800 - 1,200GWh in renewable production that is expected by 2020.
Standard warranties for lithium-ion batteries covering both performance and defects are two years, but extended warranties can be purchased. A warranty beyond ten years does not make sense because so much of the battery would need to be replaced after year ten. Insurance can also be purchased. Operations and maintenance of batteries is complicated because the operator relies on software to optimize performance. Rates of deterioration of the battery depend on how the battery is used. A group of storage experts and a tax equity veteran talked about these and other subjects at Infocast Storage Week in San Francisco.
Utility Southern California Edison (SCE) recently selected a roster of energy storage projects to supply local capacity needs around the coastal city of Oxnard instead of the 262MW t natural-gas peaker plant it had chosen previously. If regulators give their approval, Strata Solar will build and own a 100MW/400MWh system in Oxnard, and dispatch it on behalf of SCE. This system will tie for largest lithium-ion battery in the world when it comes online in December 2020. The AES Alamitos plant of the same size is due around the same time.
