3550 Guidance on adapting combined cycle gas turbine (CCGT) power stations for hydrogen combustion

Overview:

In line with the UK’s commitment to integrate 2–5% hydrogen into the national natural gas transmission system by 2025, this guidance document is designed to assist power station operators in understanding and preparing for the introduction of hydrogen-natural gas blends and the subsequent impact on gas turbine operations.

Key Features of the Guide:

• Offers an examination of the effects of hydrogen integration on gas turbine power stations.
• Provides actionable recommendations for modifications to support hydrogen blends ranging from 2% to 100%.
• Includes findings from a specialized workshop that addressed the influence of hydrogen on essential plant components.

The Guide Covers:

• Regulatory Context: A thorough overview of the current and forthcoming legal considerations.
• Characteristics of Hydrogen: An analysis of hydrogen’s properties.
• Risk Management: Guidance on conducting risk assessments and establishing safety protocols.
• Maintenance Considerations: Advice on maintaining operational efficiency with hydrogen blends.
• Safety Measures: Strategies for ensuring process and occupational safety.
• End-of-Life Planning: Information on decommissioning considerations for plants using hydrogen.
