We are passionate about the sea.

We bring the rigor, experience and execution capability of renewable energy to the ocean to develop regenerative infrastructure at scale.

InvestableProfitableScience-drivenLarge scale

“The only way to tackle the massive challenge of restoring and conserving degraded natural capital is by making the solution investable, profitable, sustainable, science-driven and at a large scale. 70% of this effort must take place in our oceans.”

Emotion moves us to action

We want to see the sea clean, healthy and full of life, and to benefit from what it offers us in a regenerative and sustainable way, not an extractive one. Two emotions and one discovery led us to create Nautilus.

  1. A negative emotion

    The plastic
    drama

    Every time we dive, in any corner of the planet, we come across it.

  2. A positive emotion

    The ocean
    revives fast

    In a well-managed Marine Protected Area we saw how, just two years after protection began, life regenerated in an astonishing way.

  3. A discovery

    Restoring and conserving
    marine ecosystems
    is now investable

    Science is making it possible for the restoration and conservation of marine natural capital to no longer rely solely on philanthropy. Today we can measure, value and finance the environmental benefits of its regeneration.

What our oceans give us

  • 70%

    of our planet is covered by our oceans. The largest ecosystem on Earth.

  • 50%

    of the oxygen we breathe. The lungs of our planet.

  • 30%

    of the CO₂ we produce is absorbed by our oceans.

  • 90%

    of the excess heat generated by climate change. The No. 1 thermal regulator on Earth.

  • +700,000

    species. The foundation of human life and economies, feeding billions of people.

Human activity is devastating our oceans

  • 11Mt

    of plastic enter the ocean annually.

  • 30%

    of seagrass meadows lost in 50 years.

  • 90%

    of coral reefs have bleached since 2023.

  • $3trillion

    of funding is needed to revert this situation, according to Morgan Stanley.

What we do

At Nautilus we develop, finance, build and operate large-scale projects to restore and conserve marine ecosystems, avoid and valorize plastic pollution, and produce renewable fuels using marine biomass as part of the feedstock.

We do this through industrial projects and natural capital projects.
