Energy Storage

Closure of the large Rough storage has left the UK in a “precarious position” and “vulnerable” to gas supply shortages, Wood Mackenzie finds. Spot LNG cargoes can help cover demand at a short notice – but it would be imprudent to rely on flexible gas imports through the Interconnector, particularly as UK gas demand is bound to increase due to the government’s coal phase-out policy.

Dynamics of the global energy transition are driven by the speed of electrification and the competition between flexible gas power plants and renewables plus energy storage. Margins in the downstream power market are becoming more attractive, as price discrimination allows for better value capture downstream than in the generation business.

French utility ENGIE has deployed a 150 kW/90 kWh energy storage system in Rotterdam that is made up entirely by second-hand batteries from Renault electric vehicles. The E-STOR system, developed by Connected Energy, is supporting the Tennet electricity distribution grid.

Striving to roll-out battery storage, Duke Energy has announced to invest $500 million in several projects spread across North and South Carolina over the next 15 years. In total, the storage projects will have a combined capacity of 300 MW.

Risk of gas supply shortages this winter keeps growing in the U.S. because inventories are at record lows due to a late start of the gas storage refill season and high withdrawals. According to EIA’s Short-Term Energy Outlook (STEO) gas inventories will reach 3,263 billion cubic feet (Bcf) at the end of October – the lowest end-of-October level since 2005.

UK Power Reserve (UKPR) has awarded the second phase of its battery-based energy storage contracts to Fluence, a Siemens and AES company. The 120-MW project is underpinned by capacity contracts secured in 2016, and UKPR is now tapping Fluence technology to enhance grid flexibility with all new storage projects scheduled to be in operation by winter 2020.

ENGIE and Holyoke Gas & Electric have started operations at a 3 MW/6 MWh power storage system connected to a solar farm near Boston. Massachusetts has been one of the first U.S. states to enact an energy storage target, which helped renewables plus energy storage installations to spread and become increasingly cost competitive with fossil-fuelled power plants.

Wärtsilä has delivered and commissioned its first engine plus storage hybrid installation worldwide for Sinergy Kft, a subsidiary of ALTEO Group, in Budapest. Sinergy’s existing engine-driven plant is now optimized with a power storage solution that also incorporates GEMS, an energy management system from Greensmith Energy.

MIT researchers have developed a novel battery, based on sodium/nickel chloride electrodes and a new type of metal mesh membrane. Costs of this battery type are significantly lower due to its stronger and more flexible material that can better withstand the rigors of daily use for industrial-scale energy storage.

The U.S. Energy Information Administration (EIA) has developed an interactive dashboard showing daily and weekly updates on Lower 48 and regional storage activity, as well as market fundamentals that affect underground gas storage activity. Updates are published online and in the Weekly Natural Gas Storage Report (WNGSR).

The U.S. Department of Energy’s blue-sky research program APRA-E has handed out $28 million in R&D grants for ten projects aimed at delivering long-duration energy storage systems. The grants are funded by ARPA-E's “Duration Addition to electricitY Storage (DAYS),” targeting the development of applications with 10 to approximately 100 hours of continuous operation.

The Finish technology group Wärtsilä has delivered its first engine plus storage hybrid installation worldwide to Sinergy, part of ALTEO Group, in the Hungarian capital Budapest. The upgraded plant, running on three W34SG engines, was commissioned earlier this week and has a total output of 6 MW / 4 MWh.

Deployment of large-scale battery storage is rapidly increasing across the United States, but capital costs of energy storage systems vary greatly, dependent on the technology uses. Energy-oriented batteries systems, used for peakload shaving, are designed for longer durations and consequently have higher average costs per kilowatt and lower costs per kilowatthour. This type is mostly used in the California Independent System Operator (CAISO) area.

Energy SRS and partners have secured £727,000 in funding from Innovate UK to develop phase-2 of a gravitational energy storage. Dubbed GENSSIS, this prototype bundles the knowledge of industry and academia to deliver a gravitational storage prototype, ready for testing in 2019.

India, home to the world's sixth largest solar PV capacity, needs backup to mitigate intermittency risks. Over $200 billion would have to be spent on energy storage, considering the IEA's Technology Roadmap ‘breakthrough scenario’ where capital costs for storage are assumed to be $1 200/kW and $30/kWh in 2050.
