PTNZ Path to Net Zero
Engineering consultancy · Edinburgh & Aberdeen

Engineering the transition to a Green Economy

Hydrogen, carbon capture, renewables and industrial decarbonisation — developed, engineered and delivered by a team that has done it before. We close the gap between an ambitious net zero target and a plant that is built, commissioned and running.

Who we are

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.

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.

Full project lifecycle

One team, from first screening to steady-state operation

01

Concept

Site screening, feasibility and strategic consulting. Technology screening, partner selection and permitting strategy to de-risk the early phases.

02

FID Ready

Pre-FEED, FEED and techno-economic optimisation. Financial modelling and a risk register that stands up to investor and lender scrutiny.

03

Execution

Detailed multidisciplinary design, procurement and construction support — process, mechanical, electrical, OT and cybersecurity.

04

Operation

Commissioning, SAT, handover and operational support, with digital monitoring that keeps the asset performing over its life.

What we do

Our services

We take an idea to the point where it can be funded. Techno-commercial modelling, pre-feasibility and FEED, and the project management discipline to keep scope, cost and programme honest.

Techno-commercial modelling Pre-feasibility & FEED Project management Financial modelling Risk register & TCO

Full multidisciplinary engineering under one roof, with a bias towards modularisation and repeatable design. Specialist teams, not generalists.

Process engineering Mechanical engineering Electrical — HV & grid compliance OT & OT cybersecurity

Vendor-agnostic by principle. We write the technical specification, run the tender, evaluate bids on merit and manage the vendors through fabrication and factory testing.

Technical specification Tender & bid evaluation Vendor management FAT witnessing

Systems completion, pre-commissioning, site acceptance testing and performance demonstration — then a structured handover to the operations team.
