Which statement best explains the strategic value of hydrogen storage in systems with wind and solar?
It buffers intermittent generation over long durations
It reduces solar panel thermal losses at noon
It increases turbine speed during windy periods
It amplifies grid frequency to match demand spikes
A project without integrated infrastructure needs quick deployment to balance local demand. Which storage choice is most suitable?
Cryogenic liquid air storage with long build times
Deep geological caverns requiring complex drilling
High-voltage battery farms needing extensive grid works
Specialist hydrogen vessels with lower upfront costs
In the diagram showing a vertical well into rock layers, what process creates the underground salt cavern used for hydrogen storage?
Fracturing increases natural void spaces
Solution mining dissolves rock salt
Mechanical drilling removes rock layers
Thermal melting forms an open chamber
Using the offshore diagram with repurposed caverns and platforms, which scenario most effectively leverages existing infrastructure for low-cost, large‑volume hydrogen storage?
Repurpose natural gas caverns offshore
Use untested shallow sand formations
Construct new deepwater platforms only
Store hydrogen in surface tanks at sea
Which statement best explains why ammonia (NH3) and liquid organic hydrogen carriers (LOHCs) are used in hydrogen storage systems shown in the diagram of an NH3 molecule?
They are the only materials that bind hydrogen chemically
They eliminate the need for cryogenic systems entirely
They directly generate electricity without conversion losses
They increase energy density for storage and transport
Which infrastructure element connects clean hydrogen production to end users in cities as shown in the diagram?
High-voltage electric lines to suburbs
Transmission pipeline to city gate
Rail freight corridors to depots
Marine shipping routes to ports
Which organisation funded industry-led H21 projects to test pure hydrogen in pipelines?
Ofgem provided project funding support
BEIS provided project funding support
National Grid provided project funding support
UKRI provided project funding support
Future Billing Methodology explores options to reflect differences in what property among methane, biomethane, and hydrogen?
Molecular weight differences
Calorific value differences
Flame speed differences
Leak rate differences
In what year was the Iron Mains Risk Reduction Programme introduced?
Introduced in 2012 by regulation
Introduced in 2002 by regulation
Introduced in 1992 by regulation
Introduced in 2022 by regulation
Which realistic outcome is expected from decommissioning iron mains and replacing them with plastic pipes?
Improved suitability for transporting hydrogen
Immediate reduction in gas calorific content
Elimination of transmission network bottlenecks
Guaranteed zero leakage across all pipelines
