Energy Storage

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.

Researchers at MIT have developed a new type of battery, based on electrodes made of sodium and nickel chloride and using a new type of metal mesh membrane. Costs of the battery are significantly lower than traditional lithium-ion counterparts, researchers say, pointing out the stronger and more flexible material can better withstand the rigors of use in industrial-scale energy storage systems.

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.

Pacific Gas and Electric Co (PG&E), together with Texas-based Vistra Energy, have sought regulatory approval to install a 300-MW/1,200-MWh battery storage facility at Moss Landing in California. The project is part of a wider PG&E venture, comprising four projects with a total capacity of 567.5 MW – all due for commissioning before end-2020.

Alan Finkel, Australia’s chief scientist, has highlighted the country’s potential to become a world leader in energy storage, including renewable hydrogen. Large-scale deployment of energy storage, however, requires a smarter electricity grid and mechanisms to empower consumers to manage their costs.

Speed and scale is of the essence for new energy storage to solve intermittency issues of a renewables role-out. However, there's little political will for subsidies and critics doubt that markets alone can sufficiently reward both flexibility and storage. If not, EU member states will likely fall short of their 40% emission reduction target for 2030.

Finland’s technology group Wärtsilä has launched an integrated solar PV and energy storage to deliver a true “renewables as baseload” solution that increases resilience and efficiencies. The adaptable Wärtsilä Hybrid Solar can be supported by a power producer’s existing grid infrastructure.

June 14 – Enel Group’s first utility-scale, stand-alone battery energy storage - the 25 MW/12.5 MWh Tynemouth project - is about to start operations, supported by a four-year contract with British System Operator National Grid to provide grid-balancing services. Enel bought the storage venture from Element Power in May 2017, and invested about 20 million Euros in the overall project, including construction.

UK Power Reserve has partnered with Fluence to deliver the first phase of its 120 MW battery storage portfolio to the British power grid. Fluence agreed to provide three 20 MW storage systems at sites in the Midlands and North West using its Advancion technology. All three new sites are due operational during winter 2018/19.
