Norway engineered a floating greenhouse that produces food, fish, and clean energy — all at once

In the coastal waters near Bergen, Norwegian engineers have launched a circular floating greenhouse island that could revolutionize food and energy production. Called “Ocean Bloom”, the structure combines aquaponics, solar energy, and desalination — all within a single self-sustaining ring.

The greenhouse sits on a floating pontoon that houses solar panels, water purifiers, and wind turbines. Inside, freshwater plants grow in nutrient-rich water tanks that are fed by fish waste from integrated aquaculture systems below the surface. This closed loop ensures that no external fertilizers or chemicals are needed — only sun, air, and seawater.

At the heart of Ocean Bloom is a desalination unit powered by solar-heated steam and ocean wave motion. It converts seawater into fresh irrigation supply, while also generating enough surplus electricity to power nearby villages or data buoys.

In trials, the greenhouse produced over 5x more leafy greens per square meter than land-based farming — with zero soil, zero emissions, and nearly zero waste. Even better: it acts as a carbon sink by absorbing CO₂ through its algae bioreactor ring, helping reverse ocean acidification.

Norway plans to scale this tech to archipelagos and low-lying countries facing rising seas. Entire food systems may soon float on the water they once feared — clean, productive, and climate-proof. — in New York, NY, United States.
