Value proposition
Decarbonizes ammonia production by enabling decentralized, small-scale plants that operate at lower pressures and temperatures, allowing for cost-effective production using intermittent green hydrogen.
Products and solutions
Modular Ammonia Synthesis Units (Haber-Bosch 2.0), Green Ammonia Production Systems, Decentralized Fertilizer Production Solutions, Ammonia-based Energy Storage Systems
Unique value
Unlike traditional Haber-Bosch plants that require massive scale and constant 24/7 energy input, Ammobia’s technology is modular and flexible, designed to ramp up and down in sync with renewable energy availability.
Target customer
Industrial fertilizer producers, maritime shipping companies, and renewable energy developers seeking long-duration energy storage.
Industries served
Agriculture, Maritime Shipping, Chemical Manufacturing, Renewable Energy
Technology advantage
Proprietary reactor design and catalysts that operate at significantly lower pressures than industrial standards, reducing capital expenditure (CapEx) and enabling localized production near the point of use.
How they differentiate
Ammobia utilizes a proprietary 'Haber-Bosch 2.0' process that operates at significantly lower pressures and temperatures than industrial standards. Unlike traditional plants that require constant 24/7 baseload power, Ammobia’s modular units are designed to ramp up and down dynamically to match the intermittency of renewable energy sources like wind and solar.
