Fortress Island Pampus has released a short film that shows in ten minutes how the island generates its own energy. The production was created by Strawberry Fields on behalf of GasTerra and is available online. The core is self-energy, living off what's available, with sun, wind, biomass, and hydrogen used in conjunction and intelligently managed. The film combines calm explanations with footage of the island's energy system, so that even non-technicians understand what's happening behind the scenes.
Energy on its own power
Pampus is not connected to the grid and therefore opted for its own, fossil-free set of sources and storage. The backbone consists of solar panels and small wind turbines that supply power for a large part of the year. Electricity not immediately needed goes to a lithium-ion battery. When there is any surplus generation, an electrolyzer converts the power into hydrogen. This hydrogen is stored in cylinders and later converted back into electricity and heat in a fuel cell. This allows the island to shift a sunny or windy moment to a later time with higher demand.
The film focuses on the control system. It's not demand that determines what happens, but the available supply that sets the rhythm. During periods of strong sunshine or wind, the system automatically initiates processes that can wait, such as charging the battery or producing hydrogen. On quiet days, the fuel cell provides base power, with the battery acting as a quick buffer. This makes the entire system predictable and easy to manage, even on busy visitor days.
Biomass is a key component. Kitchen and garden waste isn't taken back on the boat, but instead goes into a digester on the island. This produces biogas that can be used for cooking and hot water in restaurants and bars. The liquid waste feeds the vegetable garden. This way, organic waste gains immediate value in both the energy system and the soil, without additional transport. According to project information, a few dozen kilos of green waste per day can generate several cubic meters of biogas. This isn't the main source, but it can be used as a flexible supplement during peak periods or when solar and wind power are less efficient.
The figures make it tangible. Project communications mention a battery capacity of several hundred kilowatt-hours, with an average on-site consumption of roughly one hundred to two hundred kilowatt-hours per day during the season. The electrolyser is modular, allowing the island to scale up hydrogen production as needed. Such concrete values help facilitate discussions about what works and what doesn't in small locations where space and grid capacity are scarce.
The film uses clear language and allows the computer conductor, as Pampus himself calls it, to do much of the work. Animations show how generation, storage, and consumption interact. The viewer sees not only what's running, but especially when it's running and why. This shifts the focus from individual devices to the interaction. It is precisely this interaction that makes the difference between theory and practice in many local energy systems.
A short film shows how supply-driven management allows solar, wind, biomass and hydrogen to work together.
On an island without a grid connection, an autonomous energy system comes to life with local resources and smart control.
Images and animations show how generation, storage, and consumption alternate for a year-round fossil-free operation.
Local waste becomes biogas, batteries and hydrogen provide range when sun and wind supply less.
Sun, wind, hydrogen and biomass
Pampus proves that a mix of sources and storage already works on a small scale. Solar and wind provide the majority of the energy. Biogas from our own waste fills gaps at the right time. Batteries provide quick balance. Hydrogen provides range during extended outages of solar and wind. The software connects these components and allows supply and demand to communicate. The result is autonomy without fossil fuels, with clear choices about when to use what.
This makes the island relevant for more than just this historic fort. Heritage sites, nature reserves, harbor islands, and remote villages often face limited grid capacity or high costs for reinforcement. The Pampus model shows that you can achieve a great deal with locally available resources, a compact digester, a robust battery, and an electrolyzer or fuel cell for long-term sustainability. It's important to design and manage it as a whole, not as a collection of individual projects.
There's also a broader lesson in energy management. Putting supply first automatically shifts consumption. Cooling can be turned on a bit earlier, a boiler can come on when the sun shines, a charging station can pause when the wind dies down. This requires clarity for users and a transparent operating system. Pampus demonstrates that this doesn't have to come at the expense of comfort or the overall experience. On the contrary, the behind-the-scenes story adds something special to the visit.
The new film is more than just a communication tool. It's a compact tour of an energy system that runs on its own power year-round. It features recognizable resources, concrete figures, and visible choices. For anyone looking for working examples on a small scale, it's a useful reference, precisely because it shows what can be achieved with what already exists.
