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.
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.
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.
