UK-based specialty chemicals company Johnson Matthey has taken over the battery material business of Swiss chemicals company Clariant for $75m.
Clariant supplies lithium iron phosphate (LFP) cathode material to the lithium-ion battery sector for automotive and non-automotive applications.
German companies Energiequelle (EQ) and Enercon have announced their plans for a 10MW-lithium-ion battery storage park in Feldheim, Germany.
The construction of the biggest battery storage park in Germany will start in June this year at EQ’s facility in Feldheim, 30 miles south of Berlin. The facility will have a storage capacity of 5MWh. Only 1% of the produced electricity in the village is actually used. The plan is to feed the system with the energy surplus of the local 72MW wind farm and participate more efficiently in the weekly tenedering for primary control reserve.
A successful lead-acid battery energy storage project in the US state of Texas could lead to more batteries on the state's grid.
Duke Energy’s pilot Notrees Wind and Battery Storage project was built near the town of Notrees with help from a $22m grant from the US Department of Energy and batteries from Xtreme Power.
The project is the US’s largest battery storage installation at a wind farm.
Between January 2013 and February 2014 the 36MW batteries, storing energy from the nearby 153MW wind farm, exported 10,000MWh to the state grid, which is run by the Electric Reliability Council of Texas (ERCOT).
“The speed and accuracy of the system’s response during the pilot confirmed the benefits of the Notrees Battery Storage Project and ERCOT has made it a permanent market service,” said Tammie McGee, communications manager at Duke Energy.
The project’s success could also lead to more Texas battery storage in future, said Suzi McClellan, state affairs director at market consultancy Good Company Associates.
“There’s definitely a future there,” McClellan said. “The batteries stabilise the voltage, provide power when the wind stops blowing or charge up when the wind power isn’t needed.”
Analysts say battery energy storage could become a larger part of Texas’ electricity infrastructure, especially since the national Energy Storage Association has begun work with ERCOT on a market redesign.
US energy storage firm AES is to build a 100MW battery energy storage plant at Northern Ireland’s biggest power station.
AES plans to build the facility at the Kilroot 660MW coal/oil power plant in Carrickfegus. The company has submitted a connection application to System Operator Northern Ireland (SONI), which operates the electricity grid in Northern Ireland.
Depending on "a suitable commercial agreement", AES could have the facility operational early in 2015.
“Leveraging existing AES infrastructure will allow us to rapidly deliver reliable, economical power resources,” John Zahurancik, vice president of AES’s energy-storage unit, said in a statement. “Storage arrays have the unique ability to participate as active power-system support with no emissions and to provide both supply and load to help manage the variability of renewables.”
EnerSys batteries are powering tunneling equipment beneath London. Its Hawker range of batteries is used in maintenance locomotives that install and inspect power cables. The 200V Hawker Perfect Plus batteries with 1240A/h or 750A/h capacities are ideal for the gruelling conditions demanded in the tunnelling work.
The valve-regulated lead-acid battery range supply high power and long running times, the construction of the plates using advanced components allows for far more efficient discharge over other batteries.
The demands of a subterranean locomotive on its power source are high. The battery must be the right size and weight for the locomotive and must work for the length, and number of, trips required on a shift.
