Energy Storage

Australian energy company Santos is about to launch the world's first battery project at its Darwin LNG export plant. It will integrate batteries at the liquefaction facility's integrated gas power unit to ensure they run more effectively and with less emissions. The project is about to enter FEED phase and is due completed in mid-2020.

Falling technology prices make solar-plus-energy storage preferable over gas peaking power plants on a levelised cost of electricity (LCOE) basis. According to Wood Mackenzie, unsubsidized utility-scale LCOE for a 4-hour lithium-ion solar-plus-storage will outcompete gas peakers in all National Electricity Market (NEM) states of Australia in 2023.

Vietnam Electricity (EVN) has awarded GE’s energy consulting arm a contract to carry out a battery storage feasibility study, funded by the U.S. Trade and Development Agency (USTDA). State-owned EVN seeks to deploy energy storage throughout Vietnam to help meet an estimated 8% annual electricity load growth through 2035.

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 says its new 1GW virtual power plant (VPP) in Britain will help bridge the intermittency challenge and aims to double capacity by the summer. Connecting gas engine-driven power units, energy storage and renewables, the VPP can react to market demand within seconds.

With variable renewables accounting for more than half of global capacity additions to 2040, utilities and power grid operators increasingly turn to energy storage to cover their flexibility requirements. The International Energy Agency (IEA) expects the cost for four-hour battery systems will fall to $220 per kWh by 2040, spurring a utility-scale deployment of energy storage of close to 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.

News in Brief

Central Hudson links solar farms to VPP

July 9 – Central Hudson Gas & Electric Corp has established its distributed generation program within the broader context of New York State’s energy plan. Together with Sensus and their Remote Telemetry Module (RTM-III), the Central Hudson will monitor decentralized solar PV backed up by flexible gas gensets.

Siemens and GREEN Solar turn German town CO2-free

July 8 – GREEN Solar and Siemens Energy are jointly developing a concept for making Herzogenrath CO2-free. The plan is to provide an energy-efficient and economical combination of solar power plants, wind turbines, batteries, CHP and combined cycle power plants, as well as heat and hydrogen storage. The hybrid system will be built on the grounds of Nivelsteiner Sandwerke and will be large enough to cover the city’s entire energy demand with zero CO2 emissions by 2030.

Denmark paves the way for Nord Stream 2

July 7– Denmark on late Monday gave the Nord Stream 2 consortium permission to utilize pipe-laying vessels with anchors in Danish waters, paving the way for the Gazprom-led consortium to complete the interconnector. Construction of the 1,230-kilometre pipeline is nearly complete, except for a final stretch of about 120-kilometers in Danish waters. The project was halted in December when the Swiss-Dutch pipe-laying company Allseas suspended works over threats of U.S. sanctions.

EPRI tests early warning system

July 6– The Electric Power Research Institute (EPRI) is conducting trial tests with multiple utilities across the United States of an early warning system. It can detect an off-gassing event as a precursor to thermal runaway up to 30 minutes prior to a cascading failure. This gives plant operators time to mitigate the problem or shut down the system.

KKR buys stake in First Gen

July 3 – Valorous Asia Holdings, owned by KKR investment funds, has bought a 11.9% stake in First Gen through a voluntary tender offer. First Gen, one of the Philippines’ largest independent power producers with 3,492 MW installed capacity, is owned by First Philippine Holdings which is controlled by the Lopez family.

Subsidy cut slashes Chinese wind turbine margins

June 19 – China’s wind turbine original equipment manufacturers (OEMs) could have their gross profit margins halved due to subsidy cuts, Wood Mackenzie forecasts. Commissioned onshore wind power capacity is expected to drop by more than 16% to 19 gigawatts (GW) from 2020 to 2021 as government subsidies were terminated. This could also lead to a 27% drop in turbine prices over the next five years, slashing OEMs’ gross profit margins by half.

PowerPHASE converts gas peakers into storage engine

June 18 – U.S. emergency power provider PowerPHASE has developed an upgrade to convert 7F gas turbine-based peaking plants (350 MW each) to a so-called Storage Engine (400 MW). The unit would be able to store 3500 MWh daily and discharge 4800 MWh daily. CEO Bob Kraft claims utility customers could dispatch the Storage Engine, despite its lower heat rate (4000), ahead of higher heat rate options (9000 for gas peakers) in a competitive market like ERCOT in Texas.
