High Integrity Heat Exchangers & Pressure Equipment for Hydrogen Applications

Hydrogen is central to the global transition towards low-carbon energy, net zero targets, and sustainable industrial processes. Graham Hart Process Technology manufactures high integrity heat exchangers and pressure equipment designed to support the safe, efficient, and reliable deployment of hydrogen technologies.

From hydrogen production and compression through to storage, distribution, and utilisation, hydrogen systems place unique demands on equipment due to high pressures, temperature variation, and material compatibility requirements. Our experience in high-integrity, safety-critical manufacturing positions us as a trusted partner within this rapidly developing sector.

Our Approach to the Hydrogen Industry

Hydrogen projects demand the same fundamentals as other safety-critical sectors:

  • Engineering integrity
  • Materials confidence
  • Precision manufacture
  • Right First Time delivery

We work collaboratively with EPC contractors, technology developers, and system integrators, supporting hydrogen projects from early design engagement through to manufacture and delivery.

Our role is to provide robust, compliant heat transfer and pressure solutions that reduce technical risk, support safe operation, and scale with future hydrogen infrastructure.

Hydrogen Capabilities & Applications

We support a wide range of hydrogen production and processing applications, including:

Hydrogen Production

  • Electrolysis systems (alkaline, PEM, and emerging technologies)
  • Thermal management of hydrogen generation processes
  • Heat recovery to improve system efficiency

Compression, Storage & Distribution

  • High-pressure hydrogen compression systems
  • Cooling and temperature control for compression stages
  • Pressure equipment supporting storage and transport infrastructure

Industrial & Energy Transition Applications

  • Hydrogen blending and downstream processing
  • Integration with existing gas, chemical, and energy systems
  • Pilot plants, demonstrators, and scale-up facilities

Engineering Integrity & Manufacturing Considerations

Hydrogen introduces specific engineering challenges, including:

  • High operating pressures
  • Temperature cycling
  • Material selection and compatibility
  • Safety-critical design requirements

Our manufacturing approach addresses these challenges through:

  • Precision machining and fabrication
  • Controlled material traceability
  • Robust inspection and quality control
  • Design-for-manufacture input to reduce risk early

This ensures equipment is engineered for long-term reliability, safety, and performance in hydrogen service.

Fit for Hydrogen & Fit for CCUS Commitment

As part of our commitment to supporting the energy transition, Graham Hart is accredited to both the Fit for Hydrogen and Fit for CCUS programmes.

These programmes provide a structured framework to assess, develop, and continuously improve our capability to manufacture high-integrity equipment for hydrogen and carbon capture, storage, and utilisation (CCUS) applications.

Building on our experience in safety-critical and regulated industries, these accreditations demonstrate that we have:

  • The manufacturing capability to support emerging hydrogen and CCUS technologies
  • The quality systems and governance expected by EPCs, operators, and infrastructure developers
  • A workforce aligned to competence, training, and continuous improvement principles

Participation in both programmes ensures our business remains aligned with:

  • Evolving technical standards and best practice
  • Scale-up and deployment challenges associated with hydrogen and CCUS infrastructure
  • Long-term reliability, safety, and performance expectations

Fit for Hydrogen and Fit for CCUS are not one-off validations. They form part of our ongoing commitment to self-assessment, capability development, and readiness for low-carbon energy projects.

Why Choose Graham Hart for Hydrogen Projects?

  • Proven experience in high-integrity pressure equipment manufacture
  • Fit for Hydrogen and Fit for CCUS accredited manufacturing capability
  • Strong alignment with safety-critical and regulated industries
  • Precision-engineered heat exchangers for demanding applications
  • Collaborative support for emerging and evolving hydrogen technologies
  • Reliable delivery and manufacturing quality you can build infrastructure around
