Turning Net Zero ambition into Engineering reality
PTNZ (Path to Net Zero) is a multidisciplinary engineering consultancy specialising in the development and delivery of complex energy infrastructure. Backed by over 60 years of combined industry experience, we provide project development, financial modelling, engineering, project delivery and technical advisory services across the full project lifecycle — from concept and feasibility studies through FEED, detailed design, procurement, construction, commissioning and operational support.
Working across hydrogen, carbon capture, renewable energy, energy storage and industrial decarbonisation, we help clients evaluate project viability, secure investment, manage technical risk and deliver robust engineering solutions that accelerate project execution and maximise long-term asset performance.
At PTNZ, we combine commercial insight with engineering excellence to transform ambitious ideas into bankable projects and resilient, high-performing infrastructure that supports the global transition to net zero.
Bridging the gap between concept and operation
Accelerate global decarbonisation through the practical, rigorous integration of renewables, carbon capture and hydrogen — engineering solutions that bridge the gap between a concept on a slide and an asset in operation.
Three principles we do not trade away
- Safety firstRigorous adherence to ISO/IEC standards, applied from the first HAZID through to handover — not bolted on at the end.
- Vendor agnosticWe hold no technology allegiances. Selection is made on merit against your project's constraints, and we can show our working.
- Digital by designData-driven from day one, so the engineering model you build in design becomes the digital twin you operate against.
- Deep, not broadSpecialist hydrogen and renewables engineers with real molecule-behaviour experience, rather than generalists learning on your project.
H₂ & Renewables focus
Specialised deep domain expertise in hydrogen molecule behaviour, combined with round-the-clock renewables integration.
FID readiness
Techno-economic modelling, risk registers and TCO views built to survive investor and lender due diligence.
End-to-end lifecycle
Single accountability from concept to commissioning — no handover cliff between the study team and the delivery team.
What each stage actually involves
| 01 · Concept | Site screening and feasibility. Strategic consulting covering technology screening, partner selection and permitting strategy development to de-risk early project phases. |
|---|---|
| 02 · FID Ready | Pre-FEED and FEED with techno-economic optimisation. Financial modelling, preliminary delivery plan, risk register and Total Cost of Ownership view. |
| 03 · Execution | Detailed design and integration across process, mechanical, electrical (HV and grid compliance), OT and OT cybersecurity — with a focus on modularisation. Procurement and construction support. |
| 04 · Operation | Commissioning, site acceptance testing and performance demonstration, followed by operational support and digital performance monitoring. |
Bring us in early — that is where we save you the most
A short conversation is usually enough to tell whether we are the right team for your project.
