    • A consortium of companies received a grant to develop a floating hydrogen and ammonia production and storage plant.
    • The project will be constructed by 2027 and connected to a nearby wind farm.
    • The unit will produce hydrogen by electrolysis of seawater and nitrogen through the use of an air separation unit, combining these in an ammonia synthesis unit.
    • The NH3 FPSO concept will be built by converting an existing very large crude carrier (VLCC) or a dedicated newbuild vessel.

    Let’s break down how this type of plant differs from traditional land-based hydrogen and ammonia production facilities, incorporating specific data points, statistics, and examples for a clearer understanding.

    Traditional vs. Floating Hydrogen and Ammonia Plants

    1. Location and Mobility

    • Traditional Plants: Typically situated on land, often requiring extensive space for operation and tied to specific geographic locations close to energy sources or ammonia markets.
    • Floating Plants: These plants are built on large vessels or platforms that float on water, usually the ocean. This mobility allows them to be relocated in response to economic or environmental considerations and positioned close to energy sources such as offshore wind farms.

    2. Resource Integration

    • Traditional Plants: Depend heavily on terrestrial energy resources, which can be limited or inconsistent, depending on regional availability.
    • Floating Plants: Often integrated with offshore renewable energy sources (like wind and solar), which can provide a more constant and abundant supply of clean energy necessary for hydrogen production. For instance, the ‘PosHYdon’ project in the Netherlands aims to integrate hydrogen production on an existing offshore platform with wind energy.

    3. Environmental Impact

    • Traditional Plants: The production of ammonia typically involves significant CO2 emissions, especially if the energy used comes from fossil fuels.
    • Floating Plants: Aim to minimize environmental impact by utilizing green hydrogen, produced through electrolysis powered by renewable energy. This method significantly reduces greenhouse gas emissions. For example, a floating plant might leverage wind energy to produce hydrogen with nearly zero emissions.

    4. Economic Aspects

    • Traditional Plants: Large-scale infrastructure and energy costs can be high due to the static nature and sometimes remote locations relative to energy or raw material sources.
    • Floating Plants: Can potentially lower transportation costs of ammonia and hydrogen to different markets by moving the production site closer to the demand centers or more economically viable locations.

    5. Innovative Examples

    • Example 1: Neom Project (Saudi Arabia) – Part of a planned $500 billion futuristic city project, integrating renewable energy sources directly with hydrogen and ammonia production facilities.
    • Example 2: Norwegian Floating Hydrogen Plant – Plans to use floating wind turbines to power electrolysis for hydrogen production, aimed at reducing reliance on fossil fuel-based energy.

    Impact and Statistics

    • Production Capacity: Floating plants can be designed to scale based on demand and available space, with some designs proposing capacities up to 1 million tons of green ammonia per year.
    • Reduction in Emissions: Studies suggest that integrating renewable energy sources with ammonia production could cut CO2 emissions by up to 90% compared to conventional methods.
    • Cost Efficiency: The cost of producing green hydrogen is expected to drop below $2 per kilogram by 2030, making it competitive with hydrogen produced from fossil fuels, which currently costs around $1-$1.8 per kg.


    Floating hydrogen and ammonia plants represent a transformative approach to industrial chemical production by integrating cutting-edge renewable energy technologies, mobility, and environmental sustainability. These facilities not only aim to tackle the technical and economic challenges associated with traditional ammonia production but also align with global efforts to reduce carbon footprints and transition towards cleaner energy solutions.
