About this update from Itm Power Plc
[{"type":"text","content":"\n RNS Number : 5662O ITM Power PLC 01 July 2010 \n \n\n1 July 2010\n \n \n \nITM Power plc (\"the Company\")\n\nHydrogen Purity Certification\n \nITM Power, the energy storage and clean fuel company is pleased to announce its participation in a Joint Industry Project (JIP) with the National Physical Laboratory (NPL) directed at establishing a suite of analytical methods for the measurement of trace-level impurities in hydrogen. The project is underway and part funded by the National Measurement Office (NMO).\n \nGreater uptake of hydrogen as a fuel will depend in part on the ability to produce low cost hydrogen which is of a sufficient purity. These purity requirements are being set out in a series of draft International Standards (ISO 14687), with differing purities depending on the appliance in question. Where hydrogen is used to fuel proton exchange membrane (PEM) fuel cells, the recommended limits of impurities permissible to avoid poisoning of the fuel cell catalysts are laid out in two ISO draft standards which are currently under development:\n \nISO/CD 14687-2: 2009 - Hydrogen fuel - Product specification - Part 2: Proton exchange membrane (PEM) fuel cell applications for road vehicles\n \nISO/WD 14687-3: 2009 - Hydrogen fuel - Product specification - Part 3: Proton exchange membrane (PEM) fuel cell applications for stationary appliances\n \nThe draft ISO 14687-2 standard is consistent with SAE J2719 - Information Report on the Development of a Hydrogen Quality Guideline for Fuel Cell Vehicles\n \nPresently, no infrastructure for measurements to such challenging limits-of-detection is available in the UK. ITM is contributing to this important project by providing samples of electrolytic hydrogen as feedstock to the analysis process and hosting sampling tests.\n \nNPL is the UK's national measurement institute and is a world-leading centre of excellence in developing and applying the most accurate measurement standards, science and technology available to man. For more than a century NPL has developed and maintained the nation's primary measurement standards. These standards underpin an infrastructure of traceability throughout the UK and the world that ensures accuracy and consistency of measurement.\n \nThis project will enable NPL to develop...
