Electrolytic H2 to comply with standards without extensive purification
September 27, 2011A joint study conducted by the UK-based ITM Power, an energy storage and green fuel company, and the National Physical Laboratory on hydrogen purity analysis revealed that hydrogen produced by electrolysis does not require extensive purification in order to comply with international standards set out in ISO/DIS 14687-2 and ISO/WD 14687-3. For the study, which was also partnered by EHA members Air Products and UK Fuel Cell and Hydrogen Association, the researchers developed analytical methods to detect trace impurities in hydrogen and concluded that electrolytic hydrogen carries sufficient purity which renders it compatible for use in fuel cell applications. The finding is crucial for the prospects of future uptake of hydrogen as a fuel since it posits there is no need for an additional purification plant to utilise electrolytic hydrogen.
