Energy Storage

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.

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.

Decentralised energy storage can play an important role within the context of tomorrow's smart grid, next to demand response by means of flexible power generation, an Eurelectric report finds.

Japan's Mitsubishi Heavy Industries has published a document entitled "MHI Environmental Vision 2030", setting out how to reach its economic targets while developing sustainable technology. One key objective is to strengthen efforts on developing technology for energy storage, MHI said.

Users of electricity storage facilities can take advantage of daily variations of the electricity prices to reduce their overall energy costs. The EIA is supporting the use of electricity storage technology as a step towards a more efficient utilisation of electricity.

March 19 - Siemens has installed a Siestorage energy storage solution at an Enel-operated pilot plant in Italy.

The plant has an output of one megavolt ampere and a capacity of 500 kilowatt-hours, Siemens' Infrastructure & Cities division said today.

The Siestorage energy storage solution was installed in Enel's the medium voltage electricity distribution network. Enel, Italy's biggest electricity producer, utilises Siestorage to a Smart Grid solutions for voltage regulation with the aim of integrating renewable energy sources into the medium voltage network.

A combination of flexible combined cycle gas turbines (CCGT) and Shallow Salt storage is "best placed" to balance electricity supply and demand in the U.K. amid a rise of intermittent renewable energy production, John Baldwin, managing director, CNG Services Ltd told Gas-to-Power Journal today.

News in Brief

Fuel switch could abate 1.2bn tons of CO2

July 19 – Some 1.2 billion tonnes of CO2 could be abated by switching to gas using existing infrastructure, if prices and regulation are supportive. According to the International Energy Agency (IEA), this would be enough to bring global CO2 emissions back down to where they were in 2013.

IEA launches methane tracker

July 18 – A new ‘methane tracker’, launched by the International Energy Agency (IEA), provides up-to-date estimates of current oil and gas methane emissions by drawing on the best available data. Analysts stressed methane emissions could be reduced by nearly half at no net cost.
