UK Hydrogen Aviation Fuel Production Facility Feasibility Study, Market Demand Outlook & Project Viability Analysis

Executive Viability Abstract

This feasibility study evaluates the development of a 50MW PEM electrolysis facility in Teesside, UK, capable of producing 8,200 tonnes of Liquid Hydrogen (LH2) per annum. With a WACC of 8.5% and strategic alignment with the UK Jet Zero strategy, the project demonstrates a base-case IRR of 14.2%, contingent on Net Zero Hydrogen Fund (NZHF) support and long-term off-take agreements with Tier-1 UK airports.

## Executive Feasibility Thesis The UK aviation sector accounts for approximately 7% of national GHG emissions. The 'Jet Zero' strategy mandates zero-emission transatlantic flights by 2050, placing green hydrogen (LH2) at the center of the decarbonization roadmap. This study focuses on a 50MW Proton Exchange Membrane (PEM) electrolysis plant located in Teesside, utilizing offshore wind via a Direct Wire/PPA model. The thesis posits that localizing production near the Humber-Teesside industrial cluster minimizes midstream transport costs and leverages existing UK government subsidies (LCHBM), making LH2 price-competitive with Sustainable Aviation Fuel (SAF) by 2032. ## Technical Feasibility & Operational Specifications ### Facility Parameters - **Electrolysis Technology:** 50MW PEM stack (Modular design for scalability). - **Annual Yield:** ~8,200 metric tonnes of Green H2 (99.999% purity). - **Liquefaction Unit:** Cryogenic processing at 20 Kelvin for high-density storage. - **Input Requirements:** 438,000 MWh/year of renewable electricity; 120,000 m³ of demineralized water. - **Capacity Utilization:** 92% (Estimated 8,050 operating hours p.a., allowing for maintenance down-time). ### Performance Assumptions - **Stack Efficiency:** 55 kWh per kg of H2 produced. - **Liquefaction Energy Penalty:** 10-12 kWh/kg (State-of-the-art centrifugal compressors). - **Degradation:** 1.5% efficiency loss per annum, with stack refurbishment scheduled every 7 years. ## Detailed Capital Expenditure (Capex) | Line Item | Unit Cost | Total (GBP) | Reasoning | | :--- | :--- | :--- | :--- | | **PEM Electrolyser Stacks** | £950,000 / MW | £47,500,000 | Pricing includes balance of plant (rectifiers, dryers). | | **Cryogenic Liquefaction Plant** | £1.2m / tonne/day | £28,800,000 | Based on 24tpd capacity requirements for LH2 aviation grade. | | **LH2 Storage (Sphere Tanks)** | £15,000 / m³ | £12,000,000 | 800m³ capacity for 5-day strategic reserve at airport gate. | | **Grid Connection & Substation** | Lump Sum | £8,500,000 | 132kV National Grid connection fees and HV infrastructure. | | **Land & Site Development** | £250,000 / Acre | £2,500,000 | 10-acre site in Teesside Freeport zone. | | **EPC & Contingency (15%)** | N/A | £14,895,000 | Engineering, Procurement, and Construction oversight. | | **TOTAL CAPEX** | | **£114,195,000** | | ## Realistic Operating Expenditure (Opex) - **Renewable Energy PPA:** £65.00/MWh. Represents 72% of total Opex. Secured via long-term contract with offshore wind operators. - **Water Supply & Treatment:** £1.80/m³. Includes municipal supply and onsite reverse osmosis filtration. - **Labour & Personnel:** £2,800,000/annum. Based on 35 FTEs including process engineers, safety officers, and 24/7 control room staff. - **Maintenance & Insurance:** £2,280,000/annum (2% of Capex). Standard industry benchmark for high-pressure chemical plants. - **Stack Replacement Fund:** £1,500,000/annum. Accrual for 7-year replacement cycle of PEM membranes. - **Total Opex per kg H2:** ~£4.10/kg (excluding capital depreciation). ## Financial Model & Sensitivity Range on ROI/IRR ### Primary Financial Assumptions - **H2 Selling Price:** £8.50/kg (Aviation Hub delivery price). - **Cost of Capital (WACC):** 8.5%. - **Project Life:** 25 Years. ### IRR Sensitivity Analysis 1. **Base Case (14.2% IRR):** Energy at £65/MWh, 92% utilization, Price at £8.50/kg. 2. **Optimistic Case (19.8% IRR):** Energy at £50/MWh (due to surplus curtailment pricing), 95% utilization, Government subsidy (LCHBM) at £1.50/kg. 3. **Pessimistic Case (6.5% IRR):** Energy at £80/MWh, 80% utilization (grid constraints), Price drops to £6.50/kg due to competitive SAF pressure. ## Regulatory & Environmental Compliance Frameworks - **Low Carbon Hydrogen Standard (LCHS):** The project must prove GHG emissions <20g CO2e/MJ LHV to qualify for UK business model support. - **Renewable Transport Fuel Obligation (RTFO):** Participation in the development of Development Renewable Transport Fuel Certificates (dRTFCs) to monetize carbon displacement. - **Health and Safety Executive (HSE):** Compliance with COMAH (Control of Major Accident Hazards) regulations due to LH2 storage volumes. - **Planning (DCO):** Required for projects over 50MW; however, Teesside’s status as a 'Hydrogen Hub' provides accelerated planning pathways via the National Planning Policy Framework. ## Strategic Takeaways - **Bankability:** The project becomes highly bankable if backed by a 10-year off-take agreement with a major airline or airport operator (e.g., Heathrow or Gatwick LH2 pipeline consortium). - **Risk Mitigation:** Exposure to power price volatility is the primary risk. A hybrid PPA/Direct Wire model is essential to decouple from wholesale market spikes. - **Scale Advantage:** Increasing the facility to 100MW would likely reduce Capex per MW by 12% due to economies of scale in liquefaction and balance of plant infrastructure.
