Energy advisory and engineering consultancy Apollo has been awarded the Phase 2 Concept Definition for the Hydrogen Offshore Production (HOP2) contract by the Net Zero Technology Centre (NZTC).
This pivotal phase builds on Apollo’s work in Phase 1 and aims to progress the design of a 500MW offshore hydrogen production facility, using the existing Ninian Central Platform substructure as a template asset.
Funded by the Scottish Government's Just Transition Fund, the HOP2 project is a flagship initiative to demonstrate the feasibility of large-scale offshore green hydrogen production. By using existing oil and gas infrastructure, the project represents a critical step in the transition to renewable energy, reducing emissions while repurposing legacy assets.
Apollo specialises in providing engineering and advisory solutions across sectors including decarbonisation, nuclear and oil and gas. The company employs more than 140 engineers and has offices in Anglesey, Pembroke, Aberdeen, Bristol, Edinburgh and Nottingham.
Apollo’s role includes:
- Developing detailed designs for topsides, integrating systems such as electrolysers, water treatment, and hydrogen compression.
- Addressing key safety and environmental challenges to ensure compliance and sustainability.
- Preparing a Class 4 cost estimate and comprehensive project schedule to support future pre-FEED and FEED phases.

Phil Westmorland, Apollo’s Director of Decarbonisation, said:
“We’re delighted to continue our partnership with NZTC and build on the successes of Phase 1. This next phase is a significant opportunity to demonstrate how legacy infrastructure can play a role in the energy transition.”
Emma Swiergon, Technology Manager at the Net Zero Technology Centre, said:
“Affordable, efficient hydrogen production at scale is key to establishing the UK as a global hydrogen leader while supporting the transition to net zero. The HOP2 project demonstrates the potential of repurposed assets to enhance hydrogen production, and with Apollo, we're excited to advance phase two.”
