Keeping the keepers' cottages lit on a wild headland

Most lighthouses are now automated, but their stations live on as heritage cottages, museums and visitor stops. Many sit on remote, windswept headlands. This page looks at quiet power for those buildings.

The light itself is not the job

Navigation lights are run by maritime authorities with their own power and backup systems, and this page is not about them. The opportunity is the station around the light: restored keepers' cottages let as holiday stays, a small museum, a visitor centre with a cafe, and workshops used by the trust or caretaker. Those buildings often sit far from the nearest line, or at its very end.

Wind is the obvious source

Lighthouse headlands are chosen for exposure, and they usually have strong wind. A turbine can feed the electrolyser whenever it blows, banking hydrogen at 30 bar or less that keeps for weeks. The fuel cell then runs cottages and the visitor centre through calm spells with no engine noise breaking the sound of the sea.

Heritage buildings are sensitive. Placing a modern enclosure and turbine near a protected station would need careful design and consent from whoever manages the heritage values, and the pilot would treat that as a first step rather than an afterthought.

How it works →

The H2OME loop: an electrolyser splits water into hydrogen, the hydrogen is stored in a tank for weeks, a fuel cell turns it into electricity for your home, and the water returns to the loop.

Loads and honesty

Cottage lighting, hot water, heaters, a museum's display lighting and humidity control, and a cafe's fridges and coffee machine together fit within 15 kW. Round trip is 30% or less, so the turbine has to be generous. Salt spray is harsh on equipment, and how the system copes on an exposed headland is something pilot sites would test.

Questions

Can it power the lighthouse light?

Navigation lights belong to maritime authorities, who run their own power and backup systems to strict standards. This page is about the heritage buildings around the light, not the navigation aid itself.

Will a turbine be allowed at a heritage site?

That depends on the site's heritage protections and whoever manages them. Some stations may not allow it. Consent and design would be the first step of any pilot, ahead of any equipment being shipped out to the headland.

How does it cope with salt spray?

The system would sit in a sealed, ventilated enclosure sheltered from the worst of the weather. Its long-term performance on exposed coastal sites is something pilot installs are designed to measure, not something we can claim yet.
