Energy Storage

MAN Energy Solutions has received the Storage Highlight award for its new energy management solution, offering scalable and CO2-neutral energy storage and sector coupling. The basic principle of MAN ETES is the reversible conversion of electrical energy into thermal energy via storage in form of hot water and ice.

Norway’s state energy group Statkraft has connected gas engine-driven power units, energy storage and renewables in Britain. The virtual power plant (VPP) has a capacity of nearly one Gigawatt (GW) and can react to fluctuating demand within seconds.

Variable renewables will make up more than half of global capacity additions to 2040, so affordable energy storage is vital to provide flexible supply and grid inertia. Analysts say the cost for four-hour batteries will fall to $220/kWh by 2040, spurring a storage rollout of nearly 220 GW.

ContourGlobal Bonaire, the Caribbean arm of London-based ContourGlobal, has selected Wärtsilä to build a 6-MW energy storage on the island to accommodate greater supply of intermittent wind and solar energy. Works on the EPC project are underway and are due to be completed in April 2019.

The sunny American Southwest is where gas peaking plants are losing out to solar-plus-storage projects, which pitch for tenders at less than $30/MWh. The cost for installing battery storage, based on a 20 MWh system with 4 hours of storage, plunged 40% over the past year to $357/kWh and Bloomberg New Energy Finance (BNEF) anticipates another 52% reduction by 2030.

Falling technology cost and supportive policies are seen pushing up the American grow from currently $400 million to top $4 billion by 2024. According to Global Market Insights, power storage could become a “market disruptor”, having nearly doubled in 2018 by adding yet another 1,000 MWh of capacity.

By 2024, China’s market for flow vanadium energy storage is likely to exceed $3 billion. The new technology is based on domestic resource and offers virtually unlimited storage capacity, long duration, and rapid response time. A 200MW/800MWh vanadium flow battery is under development in Dalian, with the batteries made in a nearby factory of Rongke Power.

Sempra Energy has sealed a deal to divest its non-utility US natural gas storage facilities for $322 million to an affiliate of ArcLight Capital Partners. Once the sale is closed in Q1-2019, ArcLight will own 100% of Mississippi Hub and Bay Gas storage facilities.

Nov 28 – Tokyo-based Toshiba will reinforce its green energy footprint by spending 100 billion yen ($175m) on a new biomass power plant near the thermal Mikawa power station in Omuta, Fukuoka prefecture. Going forward, Toshiba aims to aggregate all its renewable energy sources and storage batteries, creating a Virtual Power Plant (VPP).

Energy storage will play a growing role in the British power mix as the Brexit process is at a critical stage and the country seeks to reduce reliance on importing electricity through from mainland Europe. “Interconnectors are direct competitors in the flexibility marketplace,“ Wood Mackenzie said, suggesting Brexit could be good news for the UK storage market.

Nov 21 – Rebuking warnings of gas supply shortages, the UK government said it will not give any regulatory support for new gas storage facilities. Insisting that “the benefits of more insurance are not worthwhile,” energy secretary Greg Clarke said, insisting the market was already providing sufficient gas security and optionality.

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.

News in Brief

Mitsubishi produces methanol in Trinidad

Jan 20 – Mitsubishi Gas Chemical Company has launched commercial operations of a methanol and dimethyl ether plant in Trinidad and Tobago. The plant has an annual production capacity of one million tons of methanol and 20,000 tons of dimethyl ether, which can be used as an alternative fuel for cars and power generation.

First 8-cylinder B36:45 engine delivered

Jan 19 – Rolls-Royce has delivered the first 8-cylinder variant of its Bergen B36:45 gas engine to a tomato producer in Belgium. The medium speed genset is planned for delivery this spring and will drive an onsite power plant that generates 4700 kW electricity and 5520 kW heat. The new engine offers a 20% increase in power per cylinder and will replace an existing Bergen 12-cylinder B35:40 genset.

Moody’s upgrades Enel to Baa1

Jan 18 – Moody’s Investors Service has upgraded Enel’s long-term rating to Baa1, with a stable outlook. The upgrade reflects Enel’s progress in reducing its risk profile, analysts said, pointing at the Italian utilities ongoing investment in networks and renewables, growing geographical diversification and focus on centralised financing.

GE sues Siemens Energy

Jan 15 – General Electric has sued its German rival Siemens Energy over the alleged use of stolen trade secrets to win gas turbine contracts worth several billion dollars. GE told the US district court in Virginia that Siemens received the secret information from a Dominion Energy employee.

Orbital Energy launches Eclipse

Jan 14 – Nasdaq-listed Orbital Energy Group has launched a new subsidiary, Eclipse Foundation, a drilled shaft construction company. The new company specialises in providing services for power transmission and substations, communication tower and a disaster restoration through emergency power.

S’Korean coal and LNG imports slide

Jan 13 – South Korea’s imports of thermal coal and LNG have fallen 12% and 11%, respectively, as the government cracks down on fossil fuel usage to curb air pollution. Customs data shows that coal imports amounted to 10.2 million tons in December, down 1.4 million tons from the same month last year but up from November’s imports of 9.5 million tons.

UK’s National Grid issues supply warning

Jan 12 – Natural gas prices in the UK surged as National Grid issued warnings on supply deficit as LNG cargoes are being diverted to North Asia. Prices at the British NBP gas trading hub soared to the equivalent of $8.95 per MMBtu, while the JKM price for North Asian spot LNG cargoes for February 2021 was last at $19.700 per MMBt.

Fortistar invests in hydrogen

Jan 11 – Fortistar, a privately-held fund, has joined an equity investment of up to $157 million in hydrogen producer BayoTech.

NFE secures LNG for Puerto Rico, Mexico and Nicaragua

Dec 23 – New Fortress Energy (NFE) has agreed to purchase Henry-Hub-indexed LNG for its integrated gas and power businesses in Puerto Rico, Mexico and Nicaragua. The New York-based project developer said it now has covered 80% of its expected needs throughout Latin America, thus reducing its need for spot purchases and its exposure to changes in the market price for LNG.

China and Korea mandate coal-to-gas switch

Dec 22 – The Chinese government has launched a coal-to-gas boiler switching programme, targeting 7.1 million homes, which makes gas demand more weather-sensitive this winter. Similarly, South Korea mandated the closure of 15 coal-fired plants since the start of December in an effort to reduce air pollution. Analysts expect this will accelerate the drawdown of LNG terminal inventories going into Q1-2021.

GE repowers oil field in Brazil

Dec 21 – GE Power Conversion has been awarded a contract by Sulzer Pumps UK to supply motors for four water injection pumps of a Floating Production Storage and Offloading (FPSO) vessel.
