<strong>Hydrogen</strong> fuel price at <strong>the</strong> pump versus three elctricity prices<br />
( 50% electrolysis, 50% trucked-in gaseous hydrogen )<br />
Electricity price:<br />
€0.05/kWh<br />
Electricity price:<br />
€0.2/kWh<br />
Electricity price:<br />
€0.30/kWh<br />
Refuelling station maintenance cost<br />
Refuelling station financing cost<br />
Cost for <strong>the</strong> hydrogen (50% delivered<br />
and 50% produced from electrolysis)<br />
Average EU taxed and untaxed<br />
diesel fuel price (~ € 1.15 and<br />
€ 0.58/ litre)<br />
Assumptions:<br />
Refueling station capital cost: € 7.5million,<br />
<strong>Hydrogen</strong> purchase price: €4/kg<br />
Station maintenance fee: €225,000/year<br />
Discount rate: 3.5%<br />
Discount period: 10 years<br />
The figures assume two electrolysers<br />
with a capital cost <strong>of</strong> €300,000 each.<br />
The conversion efficiency <strong>of</strong> <strong>the</strong> process ,<br />
including gas continioning and compression,<br />
is assumed close to 65kWh/kg H2<br />
Figure 44 Estimation <strong>of</strong> <strong>the</strong> hydrogen fuel price at <strong>the</strong> pump for <strong>the</strong> refuelling station in<br />
HafenCity, Hamburg. The figures refer to three different electricity prices. The cost <strong>of</strong> <strong>the</strong><br />
hydrogen is <strong>the</strong> arithmetic average between <strong>the</strong> hydrogen purchase price and <strong>the</strong><br />
production cost from electrolysis.<br />
Figure 44 suggests that <strong>the</strong> hydrogen fuel price at <strong>the</strong> pump is likely to be at least three<br />
times higher than <strong>the</strong> average taxed diesel price in <strong>the</strong> European market, even<br />
assuming subsidised electricity prices (e.g. as low as €0.05/kWh). This result is<br />
influenced by <strong>the</strong> high capital cost <strong>of</strong> <strong>the</strong> refuelling station and, most notably, by <strong>the</strong> cost<br />
<strong>of</strong> <strong>the</strong> hydrogen itself, i.e. excluding financing and maintenance costs. This latter is <strong>the</strong><br />
key cost component and is influenced by <strong>the</strong> poor economic performance <strong>of</strong> <strong>the</strong><br />
electrolysers.<br />
There is, however, scope for substantial cost reductions for <strong>the</strong>se kind <strong>of</strong> refuelling<br />
station designs over time. Particularly as <strong>the</strong> constrained location and prototype nature<br />
<strong>of</strong> this project have increased costs significantly.<br />
