Underground Storage

In the particular study it is considered the storage facility is underground because of a few very important factors:

· Visibility for storage tanks:

It is a fact that security is enhanced if storage tanks are placed in an underground configuration. There, experts assessing their performance in short periods of time could inspect them. Direct contact with the tanks should be prohibited to everyone otherwise.

· Geology of the UK soil supports the underground storing configuration:

The UK doesn't possess any historical evidence of dangerous seismic activity in its soil. Moreover, the UK soil's condition exhibits a lack of slippage and provides adequate support in underground infrastructures. Considering these facts, plus the lack of excessive expenses demanded to built an underground infrastructure, the latter can be established as a high-potential option.

· The European Union Law and further financial incentives:

Although to this moment there is no direct legislative instrument regarding the overall assessment of performance and storage of hydrogen, the European Union Law is against over-ground storage of fuels for filling stations sites unless any special conditions apply. It is not accidental that gasoline storage tanks are supported in underground structures; this alignment is chosen clearly because of reasons that deal with tanks' dimensions and volume capacity as well as overall safety. Furthermore, additional financial incentives are provided in the case of the underground storage option in the form of supporting funds for the building of the underground infrastructure.
