13. • It’s a gas that can be produced easily with electricity and water.
Both are abundant on Orkney.
• It can be stored. Intermittent renewables controllable energy
• High specific energy density
• Variety of uses

WHY HYDROGEN (H2)?
15. • Invented in 1838
• React H2 and O2 to produce electricity and water.
2H2 + O2 2H2O
• Used in vehicles or stationary units (CHP)

COMBUSTION
H2 is a flammable gas:
• Used in boilers
• Combusted in cars (similar to LPG
conversion)
• Replacement for oxy-acetalyne
• Direct use in homes / businesses
• Injected to the gas grid (power to gas)

FEEDSTOCK FOR CHEMICAL REACTIONS
Orkney could reduce its reliance on imports while decarbonising and using
curtailed energy
3H2 + CO2 → CH4 + 2H2O Makes methane
2H2 + N2 → 2NH3 Makes Ammonia
then 2NH3 + CO2 → (NH2)2CO + H2O Makes Urea (fertiliser)
37 H2 + 12 CO2 → C12H26 + 24H2O Makes synthetic diesel

18. SURF N TURF
ORKNEY HYDROGEN PROJECTS
Surf n Turf:
Objective:
• To maximise the benefit of EMEC’s electrolyser to Orkney community
• To prevent curtailment of Eday community turbine by linking to EMEC’s
electrolyser
• To establish a protocol for moving hydrogen between islands
• To provide zero carbon heat and power to Orkney harbour
• To overcome the barriers to using hydrogen to power ships by
introducing training for crews
19. SURF N TURF
ORKNEY HYDROGEN PROJECTS
Surf n Turf:
• Infrastructure linking wind and tidal
turbines to electrolyser
• 3x bespoke tube trailers to transfer
hydrogen
• Permission from Marine and Coastguard
Agency to use ferries
• 75kW fuel cell at harbour
