History

Foundation

The airport was built and commissioned in 1940 as Royal Air Force Grimsetter , or simply RAF Grimsetter, for the defence of the Scapa Flow naval base. It took its name from the farm of Grimsetter, which the airfield was built over. In 1943, the Royal Navy took over the airbase and it was known as Royal Naval Air Station Grimsetter, commonly referred to as RNAS Grimsetter, later commissioned as HMS Robin and used by the Fleet Air Arm. Control passed in 1948 to the Ministry of Civil Aviation and in 1986 to Highlands and Islands Airports.^[3]

Accidents and incidents

Green energy

Hydrogen production by electrolysis of water was well under way in late 2020 in Orkney, where clean energy sources (wind, waves, tides) were generating excess electricity that could be used to produce hydrogen gas (H₂).^[27] A plan was under way at Kirkwall Airport to add a hydrogen combustion engine system to the heating system in order to reduce the significant emissions that were created with older technology that heated buildings and water. This was part of the plan formulated by the Scottish government for the Highlands and Islands "to become the world's first net zero aviation region by 2040".^[28]

Artwork

The airport is notable for the signage on the terminal roof written in runes. The symbols spell the word 'Krimsitir' or 'Grimsetter'^{[29][better source needed]}, the name of the bay next to which the airfield is located, which was similarly the name of the former RAF base and the name of the farm upon which the airfield was built.
