[{"type":"text","content":"\n \nRNS Number : 4656J ITM Power PLC 17 July 2013 \n \n\n17 July 2013\n \nITM Power plc\n(\"ITM Power\" or the \"Company\")\n \nTechnology Update: Performance and Efficiency improvements\n \nMajor Projects on Budget and on, or ahead of, Schedule\n \nITM Power (AIM: ITM), the energy storage and clean fuel company, announces a technology update with a particular focus on the MW scale power-to-gas technology platform together with an update on key projects on the Isle of Wight and in Germany.\n \nStack Efficiency\nThe Company is pleased to announce an overall performance improvement to its rapid response stack platform, enabling hydrogen output to be increased by 11%. ITM Power has previously described its HGas (25kg/day PEM) stack module as being capable of self-pressuring up to 80 bar and responding to changes in power in less than 1 second. Each stack is now able to generate up to 27.9kg/day at full load at an efficiency of greater than 77%. This increased stack output means the hydrogen produced from a 1MW system consisting of 16 such stacks has increased from 400 to 446kg/day. This represents a significant benefit to end users and will produce a positive impact on the economics of both hydrogen refueling and power to gas applications.\n \nStack Response Time\nThe response of an electrolyser stack is a function of both the electrochemistry of the stack and the power electronics. As part of the continuing assessment of the HGas stack platform, a suite of aggressive on/off cycles has been applied. These involve stepping the stack from 100% to 0% and back to 100% capacity every ten minutes to measure reaction time and any changes in performance. Changes in current are observed to take place in 0.2 seconds and are not changing during the testing to date.\n \nStack Testing \nTesting of the HGas stack platform continues alongside accelerated testing of all stacks and key components. ITM Power has recently completed commissioning of a new stack testing laboratory capable of running 16 fully instrumented stacks simultaneously under automated control. This testing suite will further underpin the Company's extensive work focused on the evaluation of long term effects due to cyclic operation and qualifying lower cost methods to delay them. ...
