Hydrogen, Carbon & Low-Carbon Industrial Systems

What We Do

We are a systems integration and project structuring advisory, integrating engineering, commercial and investment perspectives in low carbon and decarbonization projects.

We support industrials, infrastructure developers and investors in shaping projects from early-stage concept through to bankable definition — integrating technical architecture, phased project development, and commercial structuring.

Working either embedded within a PMO or as an independent external advisor, DecarboNexus helps turn concepts into credible, investable projects.

Our areas of focus include:
  • Industrial decarbonisation strategy
  • Integrated energy system architecture (renewables, storage, grid interaction)
  • Carbon capture, biogenic carbon utilisation
  • Hydrogen and derivative fuels (ammonia, e-fuels)
  • Integrated energy systems Techno-economic modelling and scenario analysis
  • Bankable feasibility studies and project structuring

Wietse ter Veld

Founder & Principal Consultant, DecarboNexus

Mechanical engineer and energy transition advisor with over 30 years of international experience across oil & gas, renewables, hydrogen, CCUS, and infrastructure. Since 2017, specialised in green hydrogen, ammonia, and Power-to-X — supporting developers, governments, and financiers from strategy through to project definition.

Previously: Strategic and technical advisor to AtkinsRéalis (energy transition & hydrogen); 25+ years with Schlumberger across major energy projects (upstream & infrastructure).

Wietse operates at the interface of strategy, engineering, and project development — translating technical complexity into investment-grade clarity.

APPROACH

Decarbonisation is not a single-technology problem.
It is a system challenge.

We work at the intersection of engineering, economics, and delivery — ensuring that projects are not only technically sound, but also commercially defensible and scalable in real-world conditions.

Our approach is grounded in:

Systems integration – understanding how assets, infrastructure and markts interact

Engineering rigour – grounding design assumptions in technical and physical reality

Capital discipline — focusing on what is investable, not just conceptual

Clarity and alignment — bridging technical, commercial, and stakeholder perspectives

SELECTED EXPERIENCE

DecarboNexus builds on extensive experience across energy transition and infrastructure projects, including:

Projects range from early-stage concept definition to large-scale developments requiring bankable, structured delivery frameworks.

Concept Examples

Concept Examples in Industrial Decarbonisation

Examples of integrated energy and decarbonisation systems, demonstrating how complex projects are structured from concept to investable solutions.

    • Hydrogen production via electrolysis integrated with industrial processes, utilising oxygen as a valuable co-product
    • Oxygen valorisation in combustion or process optimisation
    • Improved economics through coupling electrolyser systems with industrial host processes
    • Integration with carbon capture systems for further decarbonisation

    Focus: turning electrolyser oxygen from a waste stream into a system value driver

    • Capture and utilisation of biogenic CO₂ streams from fermentation, biomass processing, waste-to-energy, or pyrolysis
    • Biogenic CO₂ combined with green hydrogen to produce synthetic fuels — e-methanol, ammonia, or SAF
    • Alignment with low-carbon fuel standards and carbon credit frameworks

    Focus: circular carbon and high-value fuel production

    • Design of systems combining renewables, storage, and hydrogen to meet industrial energy demand
    • Solar and wind integration with electrolysis and industrial processes
    • Energy storage optimisation — battery, hydrogen, and thermal storage options
    • Reliable and consistent energy supply as a key design constraint

    Focus: structuring renewable energy systems that meet industrial process requirements

    • System-level optimisation of CO₂ capture, handling, and reuse across industrial processes
    • Integration of CCS/CCU with hydrogen production and synthetic fuel pathways
    • Matching CO₂ streams with hydrogen availability and utilisation options
    • Optimising capture cost versus utilisation value — including carbon credit and compliance frameworks
    • Project structuring with awareness of CBAM exposure, RFNBO certification, and CfD revenue mechanisms

    Focus: moving from CO₂ as waste → CO₂ as feedstock
