Energy Storage

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.

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.

Falling technology costs of solar power and heat have sparked a spree of new installations across India. The country now has the sixth largest installed capacity for solar thermal globally, according to IEA figures, however the rapid growth in solar PV deployment with its intermittent supply requires an adequate backup based on flexible gas generation and energy storage.

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.

News in Brief

San Miguel Energy claims $6.19bn subsidy for Ilijan plant

May 24 – South Premier Power Corp. (SPPC), San Miguel Energy’s development vehicle for the 1,200-MW Ilijan gas power project, has claimed that it already paid $6.19 billion in subsidies to state-run Power Sector Assets and Liabilities Management Corp (PSALM) for its financial obligations as independent administrator.

China’s CPECC to process gas from Iraq’s Halfaya oilfield

May 9 – Iraq and China Petroleum Engineering & Construction Corporation (CPECC) have signed a $1.07 billion deal to build and operate facilities to process natural gas extracted alongside crude oil at Iraq’s giant Halfaya oilfield. CPECC, an affiliate of China National Petroleum Corporation (CNPC), will process around 300 million standard cubic feet per day (mcf/d) of natural gas extracted from the field alongside crude oil, the oil ministry said.  Halfaya, operated by PetroChina, is Maysan Oil Company’s largest oilfield, producing 370,000 barrels per day (bpd) of the company’s total output of around 510,000 bpd.
Iraq continues to flare some of  gas extracted alongside crude oil but the Iraqi oil minister Thamer Ghadhban told Reuters Iraq is in talks with international oil companies to build a 300 mcf plant to process gas from the West Qurna 2 and Majnoon oilfields.

Chiyoda to get large cash injection

May 8 - Following losses of nearly $1 bill on an liquefied natural gas (LNG) plant project in Louisiana, Japanese construction company Chiyoda is to get a $1.4 bill cash injection. The company suffered a $953 mill loss in the six months to 30th September, 2018 after costs spiralled on the $10 bill Hackberry LNG plant in Louisiana, largely, due to escalating labour costs, it was claimed. Chiyoda was expected to record a net loss of about $1.4 bill for the fiscal year to March. Mitsubishi Corp, which owns a 33.4% stake in Chiyoda, and the Mitsubishi UFJ Financial Group, have agreed to provide capital while the company implements a rescue strategy, according to the Nikkei Asian Review.

The companies will digitally asses industrial control systems in both the oil and gas and power generation sectors (nuclear applications excluded). All tests will be vendor-agnostic.

UK ‘can cut emissions to net-zero’ by 2025

May 6 – Advisors to the British government have urged the Cabinet to “set and vigorously pursue” a new target to cut greenhouse gas emissions to ‘net-zero’ levels by 2050, replacing the current target of an 80% reduction against 1990 levels. The the Committee on Climate Change, which published the report, believes the new target could be achieved within the same cost-framework as the current more lenient goals.

Iraq’s gas imports from Iran bound to rise in June

May 2 – Iraq has no alternative to importing more Iranian gas to meet peak summer demand, the country’s electricity ministry said. He specified that halting imports would cost Iraq’s power grid 4,000 MW per day. Some 14 GW of Iraq’s installed capacity is run on domestic gas, and supplies from Iran keep an additional 4GW operational. “Until now, we have no alternatives to Iranian gas,” a spokesman of the energy ministry said, adding imports from Iran are expected to increase in June from currently 28 million cubic metres per day to 35 MMcm/d.
