Energy Storage

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.

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.

News in Brief

FlatFish drone inspects Shell fields off Brazil

May 25 – Shell and Petrobras have contracted Saipem to use its FlatFish subsea drone in pilot projects to inspect two ultra-deepwater oil and gas fields offshore Brazil in over 2,000-meter depth. Initial tests will be carried out at Saipem’s base in Trieste, Italy, with a view to deploying the drone to Brazilian waters in the third quarter of 2022.

Gazprom cuts off supplies to Finland

May 24 – Gazprom has completely suspended gas supplies to Gasum after the Finish company refused to pay in roubles, the two companies said in separate statements. Gasum is confident it will be able to supply all its customers with gas imported through the Balticconnector (2.6 Bcm/y) from Estonia.

Heisco wins tender in Kuwait

May 23 – Heavy Engineering Industries and Shipbuilding Company (Heisco) has won a KD1.8 million ($6.4 million) tender – floated by the energy ministry of Kuwait – to install, examine and test four high voltage transformers at the Doha East Power Generation and Water Distillation Station. Heisco, founded in 1974 and listed on the Kuwait Stock Exchange, has developed into one of the largest energy engineering groups in the emirate.

JERA issues bond to finance power plant upgrades

E.ON tells Germans how to save gas

May 11 – A large-scale switch to heat pumps, solar power and better demand-side management could help save Germany nearly 100 TWh of natural gas per year, E.ON has said, calling on households to contribute to Europe’s efforts to reduce reliance on Russian gas imports. “If 10% of the homes in Germany are equipped with solar PV installations, 20% of gas boilers are replaced by heat pumps, and the average temperature in all households is reduced by one degree Celsius on average, this would lead to natural gas savings of 103 TWh per year," E.ON Energy CEO Filip Thon said, noting this volume would equate to about 30% of Germany’s current gas imports from Russia.

Exelon Q1 earnings lower following Constellation cave-out

May 10 – Exelon has reported lower first quarter earnings and a higher operating revenue, having completed the separation of Constellation Energy – Excelon’s former power gen business. Focussing now solely on transmission and distribution, Exelon’s net income from continuing operations for the first quarter of 2022 decreased to $0.49 per share from $0.53 a share in pre-year period. In contrast, adjusted operating earnings notched up to $0.64 per share, primarily due to due to higher electric distribution earnings at ComEd from higher rate base and higher allowed electric distribution. Rate increases at Excelon’s group companies PECO, BGE, and PHI were partially offset by higher depreciation expenses at BGE and PHI.
