Wind power
(Hydropower)
How can you store hydrogen?
Hydrogen Storage
Gaseous
Containers
Gas holders, tube storage larger storage purpose
Composite tanks 350/700 bar (transportation)
Rock salt caverns (bulk storage)
Exploited oil and gas fiels
Liquid
As a compound: e. g. methanl, ammonia
hydrate; -> niche market, often too heavy and
Lyquid organic hydrogen carriers (LOHC) (energy for dehydration about 30%)
Liquifacion of H2 (losses to about 21%)
How can you store gaseous hydrogen?
How can you store liquified hydrogen?
How can you transport Hydrogen?
Pipelines
Trucks (and trains) -> up to 500 bar
Ships (technoglogy from LNG) -> LOHC
