AbstractIn April 2008, the University of Birmingham launched the first permanent Hydrogen Refuelling Station in the UK. This enabled the refuelling of the only at the time fleet of Hydrogen Hybrid Fuel Cell Vehicles (HHFCV) in the UK. To maintain the low emissions ethos, the ultra-high purity “Green” hydrogen for the refuelling station was supplied off site, from a third party contractor. The University aims to be the first campus in the UK that is carbon neutral and this project scopes to produce “Green” hydrogen on-site to power the fleet of HHFCVs. Electrolysis is currently the only commercial method for producing ultra-high purity hydrogen without the need for, what could prove to be very costly, additional purification steps. Working in collaboration with ITM Power, a HPac Model electrolyser has been installed to produce electrolytic hydrogen on-site (up to 1.25 kgH2/day). The HPac uses PEM technology, which eliminates the need for hazardous alkaline substances, to produce hydrogen. The input requirements are ASTM Type 2 de-ionised (DI), water and 240 V power supply. Hydrogen is produced at pressures up to 15 bar . However, there is a need to incorporate this unit within the existing hydrogen infrastructure incorporating 350 bar Air Product refuelling station. An integrated delivery system has been designed and initial results are presented herein.
