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 />
