SoCalGas, a gas grid operator in California, is spending £1 million on the cleantech fund LA Cleantech Incubator (LACI) to develop 'renewable natural gas.' "Biogas is one source but, in the future, we expect other pathways such as 'water splitting' through solar chemical conversion and hydrogen electrolysis to provide renewable natural gas," said Jeff Reed, SoCalGas director of business strategy and development.
Italian marine classification society RINA has approved a design for a compressed natural gas (CNG) storage system aboard vessles, which is being used as gas feed at a fuel oil peaking power plant retrofitted to run on gas in Grati, Indonesia. The 300MW unit is "the world's largest CNG storage system," according to RINA.
July 30 - Samsung Electronics Co and S&C Electric Co have joined forces to develop an energy storage project that could save Britain up to £300 million annually once 2 GW of storage is installed by 2020.
The project comes at a cost of £28.5 million and will be capable of storing up to 10 MW-hours of electricity.
As part of a 'smart grid' feasibility study, energy storage company ITM Power has launched an upgrade to its hydrogen-producing HGas electrolyser on the Isle of Wight, UK to allow more solar and wind power to come on the grid safely. Sponsored by the UK government, the study examines how HGas electrolyser units produce hydrogen gas from surplus renewable power that utilities can sell as fuel to natural gas consumers and power plants.
In an effort to curb energy bills, Japan's Ministry of Economy, Trade and Industry is using Kitakyushu City as a test bed for a hydrogen storage system integrated with controller software, solar panels and industrial CHP (Combined Heat and Power) backup. The City of Yokohama, Toyota City, and Keihanna are also part of the Japan Smart City Portal experiment, which began in 2010 and ends in 2014.
Electricity storage technologies, operating on hourly or daily timescales, tend to be deployed to take advantage of variations in the price of electricity. Researchers at the US Energy Information Administration point out that energy storage increases security of power supply as it flattens the daily load shape and integrating variable generation like wind.
May 28 - Pacific Gas and Electric Company (PG&E) and the California Energy Commission have launched a battery energy storage system pilot project in east San Jose to better balance power needs of the electric grid.
The project launch was made possible following a $3.3 million grant from the Energy Commission to PG&E that will help fund the installation and evaluation of the system.
Jan 25 - Duke Energy Renewables, part of Duke Energy's Commercial Businesses announced the completion of North America's largest battery storage project at its Notrees Windpower Project in west Texas.
The 36 MW energy storage and power management system completed testing and commenced operations in December.
Sept 21 - Going into the winter withdrawal season, gas storage volumes in the UK are on healthy levels on soft European demand for UK gas through the Interconnector, Deutsche Bank analysts said today.
Month-to-date Interconnector flows have averaged 9mcm/d this year versus 52mcm/d last year in early September (excluding the maintenance period), the bank said in a weekly commodity report.
Volumes in the UK are nearly equal to that seen last year, even with the large withdrawal in September, compared with a net injection last September into medium-range storage.
Sept 12 - Installed thermal energy storage capacity in the U.S. is forecast to rise to 7.2 GW by 2020, up from 2.7 GW in 2011, according to Pike Research.
The annual U.S. market for incremental thermal energy storage capacity totals $268 million, with 246 MW of new capacity installed in 2011, Pike Research, a part of Navigant's Energy Practice, said in a report published on Wednesday.
The strongest growth for thermal energy storage is expected to occur in Europe, as market development is supported by the European Commission's efficiency initiatives and the rise in volatile renewable electricity generation.
„Under a conservative estimate of 2020 market activity, there will be about 19 GW of cumulative thermal energy storage installations in Europe by the end of the decade, equaling 2 GW of new capacity per year by 2020," analysts at Pike Research said in the report.
Thermal energy storage is used to better utilise surplus electricity generatated at solar plant projects by storing heat for later power generation.
August 28 – ABB has been commissioned to launch the largest battery energy storage project of its kind in Switzerland together with EKZ, a power distribution utility.
ABB supplied EKZ with battery energy storage solution using Lithium-ion (Li-ion) batteries that can provide one megawatt of power during 15 minutes.
The storage facility is integrated into EKZ's power distribution network and is being used to evaluate
performance in key areas such as balancing peak loads and intermittent power supply, and the viability of the solution for grid optimization.
August 17 - Germany's municipal utility Stadtwerke Neustadt solar power developer IBC Solar have inaugurated a pilot project to store up to 200 kWh of electricity within a local grid area.
If the utility's solar plants produce more power than is required, the energy can be stored and supplied to the grid at a later point, online media solarserver.de reported on Friday.
The power storage unit helps to stabilises the local grid and reduced the need for further regional grid expansion.
