Why ammonia cracking changes hydrogen availability

Hydrogen is essential for decarbonising power, transport and heavy industry, but getting hydrogen to where it’s needed remains one of the biggest challenges to deployment.

H-Power’s HY5 ammonia cracker removes the barriers to hydrogen access by enabling decentralised, point of use hydrogen generation for operational sites. It delivers reliable, ISO compliant hydrogen on demand through a compact, modular, containerised system without reliance on hydrogen networks or long lead infrastructure projects.

An integrated hydrogen to power solution

H‑Power delivers a fully integrated hydrogen‑to‑power solution that provides customers with a simple route to clean, reliable electricity. By bringing together fuel, technology and system integration, we enable immediate decarbonisation with reduced complexity and predictable performance.

On demand hydrogen without complex logistics

Ammonia is one of the most widely produced, transported and regulated chemicals in the world. By using ammonia as a hydrogen carrier and cracking it on site, organisations can access clean hydrogen without relying on hydrogen pipelines, tankers or refuelling infrastructure.

Decarbonisation without operational compromise

Ammonia cracking produces hydrogen without CO₂ emissions at the point of use, releasing only nitrogen as a by‑product. This allows organisations to decarbonise power, mobility and heat without sacrificing reliability, uptime or output.

Compact, modular and easy to deploy

A compact, containerised design minimises site works and speeds up installation, while modular architecture enables hydrogen output to scale as demand grows.

Make hydrogen on site, not miles away

Instead of producing hydrogen centrally and transporting it at high cost and risk, ammonia cracking enables on‑demand hydrogen generation at the point of use, whether that’s a construction site, industrial facility or off‑grid location.

Make hydrogen when and where you need it

H Power’s on‑site ammonia cracking reduces hydrogen costs by removing transport and grid constraints, delivering a modular, scalable supply.

Lower‑cost hydrogen. Simpler deployment. Faster decarbonisation.

Electrolysis is limited by high electricity prices, grid constraints, water consumption, and the cost and complexity of transporting hydrogen. H‑Power removes these barriers by producing hydrogen on site from low‑cost, globally traded ammonia, eliminating hydrogen logistics and enabling immediate, scalable deployment.

Key advantages

  • Lower hydrogen cost - avoids high‑priced electricity and off‑site hydrogen production

  • Simpler architecture - no hydrogen pipelines, tankers, compression, or delivery infrastructure

  • Modular and scalable - ammonia‑to‑hydrogen systems sized directly to site demand

  • Reliable supply - based on a mature, globally available commodity

  • Deployable now - no dependency on grid upgrades, subsidies, or new infrastructure

Benefits

H‑Power turns hydrogen into a practical, on‑site energy input—available where it’s needed, when it’s needed, at a predictable cost. Operators gain a direct, actionable pathway to low‑carbon hydrogen without waiting for grid expansion or policy support, enabling decarbonisation to accelerate today.

Resilient, low‑carbon energy for energy‑intensive industries

With H-Power’s HY5, hydrogen becomes a controllable on‑site energy source, cutting emissions and strengthening operational resilience without the cost, delay, or grid dependency of large‑scale electrolysers.

Key advantages

  • Lower‑carbon energy inputs without exposure to volatile electricity prices

  • Reduced Scope 1 emissions by displacing fossil‑derived hydrogen and fuels

  • Operational resilience independent of grid constraints or subsidy frameworks

  • Modular deployment aligned to real industrial demand

Industrial applications

  • Petrochemicals - on‑site hydrogen for hydrotreating and desulphurisation

  • Iron & Steel - supplemental hydrogen for fuel switching and decarbonisation trials

  • Cement - hydrogen for kiln decarbonisation where electrification isn’t viable

  • Chemicals - reliable feedstock decoupled from power‑price volatility

  • Glass - low‑carbon hydrogen for high‑temperature flame‑based processes

  • Ceramics - practical hydrogen for kilns and furnaces without major redesign

Benefits

Ammonia cracking gives industrial operators a predictable, on‑site low‑carbon energy source, supporting emissions reduction, production continuity, and competitiveness without waiting for grid upgrades or long‑lead infrastructure.

Ammonia to Hydrogen: A Practical route to transport decarbonisation

Ammonia cracking enables on‑site hydrogen production for transport refuelling, delivering clean fuel without waiting for grid upgrades, pipelines, or large‑scale hydrogen infrastructure.

Key advantages

  • Zero‑emission hydrogen aligned with transport decarbonisation targets

  • Rapid deployment without grid constraints or centralised hydrogen supply

  • Lower‑risk logistics using ammonia, a globally traded, energy‑dense carrier

  • Scalable support for fleet and mobility operators’ net‑zero strategies

Benefits

Deploy clean hydrogen where and when it’s needed, supporting fast, practical rollout of low‑carbon transport without compromising range, uptime, or operational performance

Ammonia fuel integration: A practical path beyond diesel

H-Power’s solution enables clean ammonia‑to‑hydrogen combustion by integrating cracking technology with conventional four‑stroke engines, delivering a low‑emission alternative without full engine replacement or major redesign.

Key advantages

  • Convert existing diesel engines with minimal modifications

  • Low‑emission operation for heavy‑duty and high‑energy applications

  • Phased transition that reduces capital risk and avoids asset write‑off

  • Suitable for demanding sectors including marine, defence, mining, and heavy plant

Benefits

Adopt clean ammonia‑fuelled engine systems without sacrificing load, range, or durability, enabling a practical, lower‑risk transition away from diesel across hard‑to‑abate sectors.

Lower Emissions. Cleaner Sites. Proven Performance.

H-Power’s HY5 enables on‑site production of low‑carbon hydrogen from ammonia, reducing fossil‑fuel dependence and eliminating transported, compressed hydrogen. It provides organisations a practical, infrastructure‑light route to measurable emissions reduction under growing regulatory and stakeholder pressure.

Key advantages

  • Reduced Scope 1 emissions by replacing diesel‑derived hydrogen and fossil fuel inputs

  • Lower site emissions by removing hydrogen transport and associated energy losses

  • Improved local air quality through reduced combustion‑based energy use

  • Support for regulated and sensitive sites including clean‑air and low‑emission zones

  • Transparent, auditable data for ESG and sustainability reporting

Benefits

Hydrogen becomes a controllable, on‑site low‑carbon energy source, allowing organisations to make tangible ESG progress today while maintaining operational continuity and meeting environmental needs.
