Worksheet time: 5mins
Which energy-sector opportunity enables transport of hydrogen using existing infrastructure?
Re-purpose natural gas pipelines for blended hydrogen
Construct entirely new nuclear transmission corridors
Replace all compressor stations with solar arrays
Decommission pipelines and switch to rail tankers
A company plans to capture CO2 from a fossil-fuel power plant and store it offshore. Which storage option aligns with UK strategies?
Pipeline to onshore salt caverns in the Midlands
Disperse at sea surface to aid natural absorption
Store in above-ground tanks near coastal refineries
Inject into depleted North Sea O&G fields under seabed
In a proton exchange membrane fuel cell, which component selectively allows protons to pass while forcing electrons through an external circuit?
Hydrogen storage tank and regulator
Polymer electrolyte membrane (PEM)
Cathode flow plate with catalyst layer
Anode flow plate with platinum catalyst
Which balanced description best identifies the net product formed at the cathode when hydrogen reacts with oxygen in a PEM fuel cell?
Water is formed as H+ and e− combine with O2
Heat forms as electrons neutralize hydrogen ions
Carbon dioxide forms from oxygen reduction
Hydrogen gas reforms as electrons recombine
A vehicle’s hydrogen fuel cell system is stated to achieve up to 60% efficiency in producing electricity, while a typical internal combustion engine converts fuel to kinetic energy at roughly 25% efficiency. Which implication is most accurate for drivetrain energy use?
Fuel cells deliver less usable energy per unit fuel
Both deliver equal usable energy per unit fuel
Engines deliver more usable energy per unit fuel
Fuel cells deliver more usable energy per unit fuel
In the UK context shown, which statement best characterizes hydrogen’s current cost position relative to fossil fuels?
Hydrogen already costs less than fossil fuels now
Hydrogen is at significant cost disadvantage today
Hydrogen is cheaper only after carbon taxes apply
Hydrogen and fossil fuels cost roughly the same today
Which challenge must be demonstrated at scale before wide deployment of hydrogen across homes and networks?
Immediate grid parity in electricity prices
Universal vehicle adoption without incentives
Proven CCUS integration and appliance readiness
Elimination of all transmission infrastructure
Which barrier most directly addresses public concerns about hydrogen vehicle safety shown in the image of a hydrogen car experiment?
Policy and regulatory uncertainty in development
Public acceptance requiring safety assurances
Supply chain and skills development needs
Coordination of production and storage flexibility
A plan aims to expand UK hydrogen refueling from 15 stations to meet growing demand. Which strategy best aligns with enabling a hydrogen economy while avoiding stranded assets?
Delay infrastructure until policies are final
Focus only on gas network integration
Coordinate supply and demand with flexible storage
Build many stations before vehicles exist
Which action should be prioritized during an unplanned hydrogen leak with visible flames in a process unit, as shown, to limit escalation before responders arrive?
Initiate emergency shutdown and isolate fuel sources
Increase monitoring while keeping production running
Begin standard commissioning tests on nearby equipment
Continue scheduled maintenance to avoid delays
