Slashing mineral supply chain footprints

We enable the circular economy by transforming ocean minerals and CO₂ into sustainable metal powders.

At Hydrophis, we harness the power of the ocean to produce eco-friendly, high purity mineral products for industrial use.

Our low-energy chemical precipitation process makes ultra-white metal carbonates and hydroxides from waste desalination brine and CO₂ gas.

Our Business Model

At Hydrophis, producing mineral compounds for the climate transition is not just about chemistry and engineering – it’s about balancing innovation, sustainability, and economics. 

Circular economy: We are creating quality mineral compounds that seamlessly integrate into existing supply chains and deliver environmental benefits. Our industry partners can both provide feedstocks of waste brine / CO₂ and incorporate our end products.

Owner-operator and licensing: Currently designing our Demonstration Plant for its planned 2026 launch, we are also expanding our network of licensing partners, both inbound and outbound.

Corporate Overview

Founded in the United Kingdom in 2019, our vision is to become a profitable business in the CO₂ utilisation space. 

Hydrophis is harnessing the power of the ocean to create sustainable mineral compounds. Over the past five years, we’ve completed extensive R&D into marine-based mineral production. Our expert scientists, engineers, and innovators have experience in technologies including:

  • 1
    Enzymatic gas conversion based on biomimicry of sea snakes.
  • 2
    pH swing chemistry for efficient mineral precipitation.
  • 3

    Nano-filtration for precision brine management.

Now in Technology Readiness Level 8, our technology has been proven to work in its final form and under the expected conditions. We are currently designing our Demonstration Plant.

We will piggyback on existing desalination infrastructure around the globe and contribute to the fight against climate change.
