Hydrogen Sensor in Systems for Alternative Fuels

Hydrogen Sensor in Systems for Alternative Fuels

Peer-reviewed article not indexed in WoS or Scopus

Over the last decade, the expected shortage of fossil fuels, the threat of global warming caused by CO2 greenhouse effect, and the problems of worldwide pollution, all have lead to an increasing interest in hydrogen based energy systems. Most these are intended for the transport sector, so hydrogen-fuelled vehicles based both on modified combustion engines and fuel cells have become a target for intensive research and development1. According to the European Commission White Paper on Transport COM(2001)370, hydrogen, as an alternative fuel, is envisaged to substitute for a significant part of fuel consumption in Europe by the year 2020, and it may also substitute partially natural gas, using, at least some of, the same infrastructure2. The technical issues and future directions for hydrogen storage solutions are not yet satisfactorily solved. However, safety considerations imply that adequate monitoring of the surrounding of any hydrogen facility will be necessary. Further more in efficient design, operation and maintenance of such facilities, safety will come from the deployment of adequate systems for the detection of unwanted releases, or hydrogen sensors; for fuel cells systems, the use of sensors for regulating of the fuel composition will also be a necessity.
