<strong>Hydrogen</strong> <strong>Fuel</strong> <strong>Cell</strong> <strong>Bus</strong> <strong>Technology</strong> <strong>State</strong> <strong>of</strong> <strong>the</strong> Art Review<br />

environmental friendly sources in future.<br />

Figure 42, below, captures <strong>the</strong> economics <strong>of</strong> <strong>the</strong> refuelling station in terms <strong>of</strong> final<br />

hydrogen price at <strong>the</strong> pump, considering a discount period <strong>of</strong> ten years, a discount rate<br />

<strong>of</strong> 3.5% and three different prices for <strong>the</strong> liquid hydrogen (€1/kgH2, €3/kgH2, €6/kgH2).<br />

The figures refer to two dispensing capacities, 320kgH2/day and 1,000kgH2/day. In this<br />

higher capacity case it is estimated that a refuelling station has a capital cost 25%<br />

higher, due to extra equipment.<br />

Figure 42 Estimation <strong>of</strong> <strong>the</strong> hydrogen fuel price at <strong>the</strong> pump for <strong>the</strong> refuelling station in<br />

Leyton, London. The figures refer to three different purchase prices <strong>of</strong> <strong>the</strong> liquid<br />

hydrogen and two dispensing capacities.<br />

Figure 42 suggests that for dispensing capacity <strong>of</strong> 320kgH2/day <strong>the</strong> hydrogen fuel price is<br />

likely to be higher than <strong>the</strong> average taxed diesel price in <strong>the</strong> European market, even for<br />

low liquid hydrogen prices. In this latter case <strong>the</strong> major cost component is <strong>the</strong> capital<br />

cost <strong>of</strong> <strong>the</strong> refuelling station itself.<br />

The figure also suggest that <strong>the</strong> price at <strong>the</strong> pump can be substantially lowered moving<br />

toward larger dispensing capacities, to <strong>the</strong> point that it is possible to reach a cost parity<br />

with <strong>the</strong> taxed diesel price for a dispensing capacity close to 1,000kgH2/day and a liquid<br />

hydrogen price close to €1/ kgH2 (break-even at 850kgH2/day and €2/ kgH2).<br />
