In references from the USA, land cost has been reported to be little less than thecapital cost for the station 8 .Figure 3 An overview of the connected components of an electrolytic fuel station anno 2003.For the purpose of simulation the configuration, size and load can be varied theoretically between thecomponents to find the optimal running conditions according to demand or other criteria 9 10Electric-current density is low when applied for today’s technology, typically 1 – 2kA/m 2 . In addition to significantly improving the energy consumption, it also dictates thenumber of cells and hence the area or footprint required. An increase in current density inthe magnitude of 5 – 10 times, without a significant increase in power consumption, as isexpected in future electrolysers.
