Filling Station Storage Infrastructure
In order to perform a study for the Hydrogen
round trip efficiency a decision regarding the most appropriate storing technique
was made. The careful examination of the technologies available revealed two
potential choices: the Compressed Hydrogen gas and the Liquid Hydrogen techniques.
The choice was made taking under consideration factors of cost-efficiency; progress
in the laboratory environment and the degree of applicability in the next ten
years. Especially in the last part, both technologies are already operational
and have been tested successfully in experimental stations globally.
At a second stage, additional research was performed to identify the most suitable
for the particular filling station. Research revealed that the Compressed Hydrogen
gas technique is the best-suited hydrogen storing technique. Choosing the particular
method from its potential rival lies on the fact that it is more cost-efficient
than the Liquid Hydrogen storing technology (it requires a large capital cost
of building the pressure vessel and acquiring the compressor but no additional
cost for chilling the hydrogen, are accounted). It also involves less mechanical
infrastructure and is ideal for storing hydrogen for small periods of time.
The application of the Liquid Hydrogen storing technology could only be considered
if the hydrogen was produced in larger quantities; was sold in bulk quantities
and required to remain stored for a period of at least 30 days before purchase.
In this case, the excessive operational cost could be stabilised by the high
volumes sold and a predetermined high selling price.
