Hydrogen Fuel Cell Bus Technology State of the Art Review €18 €16 €14 €12 €10 €8 €6 €4 €2 €0 Hydrogen fuel price at the pump versus three elctricity prices ( 50% electrolysis, 50% trucked-in gaseous hydrogen ) Electricity price: €0.05/kWh Electricity price: €0.2/kWh Electricity price: €0.30/kWh Refuelling station maintenance cost Refuelling station financing cost Cost for the hydrogen (50% delivered and 50% produced from electrolysis) Average EU taxed and untaxed diesel fuel price (~ € 1.15 and € 0.58/ litre) Assumptions: Refueling station capital cost: € 7.5million, Hydrogen purchase price: €4/kg Station maintenance fee: €225,000/year Discount rate: 3.5% Discount period: 10 years The figures assume two electrolysers with a capital cost of €300,000 each. The conversion efficiency of the process , including gas continioning and compression, is assumed close to 65kWh/kg H2 Figure 44 Estimation of the hydrogen fuel price at the pump for the refuelling station in HafenCity, Hamburg. The figures refer to three different electricity prices. The cost of the hydrogen is the arithmetic average between the hydrogen purchase price and the production cost from electrolysis. Figure 44 suggests that the hydrogen fuel price at the pump is likely to be at least three times higher than the average taxed diesel price in the European market, even assuming subsidised electricity prices (e.g. as low as €0.05/kWh). This result is influenced by the high capital cost of the refuelling station and, most notably, by the cost of the hydrogen itself, i.e. excluding financing and maintenance costs. This latter is the key cost component and is influenced by the poor economic performance of the electrolysers. There is, however, scope for substantial cost reductions for these kind of refuelling station designs over time. Particularly as the constrained location and prototype nature of this project have increased costs significantly. 106
Hydrogen Fuel Cell Bus Technology State of the Art Review The hydrogen refuelling station project in Whistler, British Columbia Location: Whistler / British Columbia / Canada Timeline: In service since November 2009 Project Summary: One large refuelling station (dispensing capacity of 1,000kgH2/day) based on trucked-in liquid hydrogen for the refuelling of twenty 12m hybrid fuel cell buses Project Manager: BC Transit (www.transitbc.com) Project Partners: Air Liquide Canada, Government of British Columbia, Canada‟s Public Transit Capital Trust, Government of Canada Refuelling Station Specifications: Refuelling station capital cost Capacity 1,000 kgH2/day Hydrogen purchase price Hydrogen source Refuelling concept Cascade refuelling On-site storage design Confidential. BC Transit awarded in December 2007 CAD $20 million contract (approx. €14 million) to Air Liquide Canada for the construction of the refuelling station in Whistler, a small mobile refueler and the provision of hydrogen for refuelling twenty buses for five years Confidential. The hydrogen purchase price was negotiated by BC Transit and Air Liquide as part of the 5-year liquid hydrogen supply contract The hydrogen is produced from electrolysis (powered by hydroelectricity), liquefied and trucked-in in liquid phase on weekly basis from Bécancour, Quebec (some 5,000km away from Whistler) The on-site storage system is characterised by two storage tanks, which can store up to 10 tonnes of hydrogen in liquid phase, and the necessary equipment for refuelling from liquid hydrogen (hydrogen compressor, vaporisers, etc. – see Error! Reference source not found., below). The refuelling station is designed to ensure 99% availability 24/7 107
