- 9. Internal Use Internal Use What is the Problem We must make heat flexible. This means shifting demand to reduce peak demand. Decarbonising heat is one of the biggest challenges we face on the journey to net zero. Heating and hot water are responsible for 21% of UK carbon emissions. Electrification will be a key enabler however networks will be overloaded without intervention.
- 10. Internal Use Internal Use Project Overview Flexible Heat - demonstrating smart control and domestic Thermal Energy Storage to unlock flexibility from heat. We partnered with key players in the development, manufacture and deployment of innovative heating solutions and Thermal Energy Storage to deliver the project.

- 19. 19 Heat Balance SIF project Future Networks Show and Tell 19 May 2022
- 20. 20 The problem Heat (gas) demand vs. electricity demand • The peak demand for heat is 4 times that of electricity • There is a huge variation in heat demand between seasons as well as in-day • To supply this load profile from non-dispatchable renewables would require infrastructure with massive over-capacity • To smooth heat demand, large-scale long-term energy storage will be essential in the future energy system
- 21. 21 The Problem Constraint map • Transmission constraints are already an issue in Scotland • Renewable generation needs to quadruple • Constraint payments associated with SCOTEX boundary expected to peak at £1bn per year Wind constraints
- 22. 22 Opportunity • Utilising constrained wind to produce and store heat at a large Thermal Energy Storage Sites • For Seasonal supply to Energy Centres and Heat Networks Large thermal energy storage (LTES) is one of the lowest cost forms of storage
- 23. 23 Project Overview Technical Work Package Investigate the different options for LTES and assess their compatibility with GB – geology, geography and demographics. Commercial Work Package Determine the benefits of LTES to the wider energy system including electricity transmission & distribution networks.
- 24. 24 User Needs LTES Developers/Heat Network Operators • A clear pathway/guide to deployment • An understanding of the business case • Funding sources and return on investment. Electricity Networks • Understanding of the potential flexibility • How to help facilitate the solution • Commercial arrangements • Regulatory considerations
- 25. 25 Large scale TES Energy storage compensates for the intermittent power generated from renewable power sources. Allows this power to be stored when the wind is high and the power released and utilised during peak demand periods. Aquifer Thermal Energy Storage Pit Thermal Energy Storage Borehole Thermal Energy Storage Mine Thermal Energy Storage
- 26. 26 Technical Work Package – Findings • In conjunction with heat production units, LTES can provide Electricity network services support such as frequency response and balancing (assuming there is storage capacity) • Heat Pump based systems can have a COP of 4 or more • UK has a significant proportion of high-quality aquifers suitable for ATES • Low Estimates of 16 ExoJoules or 4,000,000 GWhr • Flooded mines also provide a significant opportunity for LTES • Significant expansion in heat networks is planned in the UK with the Green Heat Network Fund • Easter Bush campus modelled as a case study of LTES for seasonal storage
- 27. 27 Commercial Work Package - Benefits Financial benefits of LTES • Use otherwise curtailed renewable generation • Reduce electricity network reinforcement • Can reduce size of heat provision systems by smoothing demand • Shift energy purchase to low cost electricity periods • Balancing and support for the electricity system
- 28. 28 Commercial Work Package – Case Study Weekly electricity demand provided by the grid for the base case as well as the HP and resistive heater cases for Kilgallioch wind farm • Long term storage using borehole thermal energy storage (BTES) • Using curtailed energy from local wind farms (e.g. Black Law & Kilgallioch) • Positive IRR demonstrated • Significant carbon reduction • Significant reduction of non- curtailed electricity use during the winter period
- 29. 29 Look Ahead The technology exists but hasn’t been implemented in GB. We need to address multiple stakeholder requirements: • A guide and evaluation matrix for potential LTES schemes • Understand the socio-environmental factors • Propose a commercial framework • How can the benefits be stacked to fund the infrastructure investment? • Address any regulatory barriers • Heat storage • Electricity network • Demonstration project to de-risk future schemes

- 43. 43 Introduction Innovation Challenge 4: Heat || Hydrogen Barrier Coatings for Gas Network Assets | Show & Tell Webinar Problem Addressed • Around 23 million homes in UK are currently heated by natural gas, supplied via the National Transmission System • Green hydrogen, generated via renewable energy, has potential to be a zero-carbon replacement for natural gas for heating • Re-purposing the existing National Transmission System for hydrogen would provide resilience and storage, rather than relying on transient production • However, hydrogen has been shown to embrittle certain pipeline materials thereby reducing allowable operating parameters • Hydrogen barrier coatings applied to the internal surface of the pipelines could prevent the need to replace the assets Project Objectives & Team Barrier Coatings • Suitable barrier coating materials and deposition techniques screened and candidates selected • Target assets/components for barrier coating deployment determined New Pipeline Materials • Suitable new pipeline materials for hydrogen identified Commercial Viability • Key commercial drivers for applying barrier coating existing assets established • Cost inputs of new pipeline materials understood
- 44. 44 Asset Prioritisation • Via meetings with National Grid Gas Plc Subject Matter Experts, gas facing assets were identified and then prioritised based on the following criteria: - Qualitative risk associated with asset - Qualitative likelihood of hydrogen barrier coating success • High Priority assets for barrier coatings shown in table • Medium Priority Assets: - Scrubbers - Condensate Tanks - Instrumentation Pipework - PIG Traps - Flanges - Preheating Units - Flow and Pressure Regulator Actuators - Recompression Units - Insulation Joints - Grouted Tees Hydrogen Barrier Coatings User Needs || Hydrogen Barrier Coatings for Gas Network Assets | Show & Tell Webinar Asset Image Prioritisation Rationale Comments Filter Casing • Relatively good access (medium sized components) • Significant quantity on NTS (>280 units) • Can be isolated and removed (no requirement to coat “live”) • Erosion resistance required • Need for hydrogen damage mitigation to be confirmed Above & Below Ground Pipework • Below ground pipework makes up large majority of NTS by volume (> 7600 km) • Ability to re-purpose NTS strongly influenced by ability to mitigate hydrogen damage in below ground pipework • Challenges due to sheer extent of network and access points can be up to 68 km apart • Access possible via Pipeline Inspection Gauges (PIGs) for majority of pipe, however significant lengths are unpiggable Pipe Girth Welds • Below ground pipework makes up large majority of NTS by volume, contains girth welds every 10-12 m on average (>690,000 estimated to be on NTS) • Ability to re-purpose NTS strongly influenced by ability to mitigate hydrogen damage in below ground pipework including girth welds • Currently uncoated bare metal surface Valves (including ball, needle, plug, non- return) • Very high number of valves on NTS (> 8900 units), critical components • Many of below ground and so cost of replacement would be high • Effective coating of valve internals very challenging • Need for hydrogen damage mitigation to be confirmed

- 50. 50 • Review of current National Transmission System materials was undertaken to identify likely highest risk sections - Additional projects being undertaken to validate and quantify risk • Requirements for new line pipe materials were determined via meetings with National Grid Gas Plc Subject Matter Experts - Requirements carried over from existing pipes standards: ◦ IGEM/TD/1 Steel pipelines and associated installations for high pressure gas transmission ◦ IGEM/TD/19 Reinforced thermoplastic pipelines for high pressure gas transmission • As installation, operation and maintenance requirements are highly dependent on the material technology, the current steel processes and standards were considered as the benchmark.

- 51. 51 || Hydrogen Barrier Coatings for Gas Network Assets | Show & Tell Webinar New Line Pipe Materials Work Package Aims & Findings • Identify state-of-the-art in plastic and composite pipelines - Both thermoset Glass Reinforced Epoxy (GRE) and Reinforced Thermoplastic Piping (RTP) systems are available. GRE pipes can be produced at large diameters, with high pressure ratings and lengths up to 12 m. - Spoolable RTPs can have lengths up to 1000 m but diameters are limited to maximum 10”. • Identify user requirements, industry challenges, regulator feedback, and future needs for H2 pipelines - Transmission pipe systems require high pressures (>50 bar) and diameters (>500 mm) which rules out spoolable RTP systems. • Identify potential and applicability of composite materials for H2 pipelines with a special focus on material selection for low permeability, H2 embrittlement and high burst pressures (50-90 bar) - Most polymers are unaffected by H2 and do not show H2 embrittlement. Highly crosslinked epoxy resins have relatively low permeability compared to thermoplastics like HDPE. • Identify potential Fibre Reinforced Polymer piping design concepts for achieving technical targets - Glass epoxy pipes have the highest potential for H2 transmission pipes. • Identify potential manufacturing, joining and health monitoring technologies - Large-diameter GRE pipes can be produced by helical filament winding, joining systems include adhesive bonding or thermoplastic welding. In-situ condition monitoring can be integrated using e.g. optical fibre technology. • Identify potential UK industrial partner for future development (Alpha/Beta) - Future Pipe Industries for GRE pipes
- 52. 52 Reinforced Thermoset Pipes Glass reinforced epoxy (GRE) pipes are manufactured by a helical winding process. This technology has been extensively used for piping within the oil & gas industry. Currently R&D is being undertaken to develop the technology for deployment in hydrogen service. • GRE pipes have excellent hydrogen permeation resistance compared to alternative thermoplastic pipes • GRE pipes can be produced in large diameters that match current network operating conditions. • GRE pipes are also unaffected by hydrogen embrittlement • GRE pipes have a low environmental impact • Joining technologies are available based on adhesive bonding • A current producer of GRE pipes is Future Pipe Industries Ltd • Pricing for a DN400 and DN500 GRE pipe are around £250 and £350 per metre || Hydrogen Barrier Coatings for Gas Network Assets | Show & Tell Webinar New Line Pipe Materials Project Findings – State-of-the-art in FRP Pipes
- 53. 53 Reinforced Thermoplastic Pipes Reinforced thermoplastic pipes (RTP) are manufactured in continuous lengths up to 1000 m by a (co-)extrusion process and typically combines a three-layer structure: (1) a thermoplastic (HDPE) inner liner (2) reinforced by a helically wrapped tape containing continuous fibres (3) protected by a thermoplastic outer coating or “jacket”. In the case of hydrogen an additional polymeric (e.g. EVOH) or metallic (e.g. aluminium) barrier layer can be included in the pipe design. • RTP exhibits good performance in hydrogen service when produced utilising polymer or metallic internal barriers • RTP offers rapid deployment, low cost of installation and is ideal for decentralised high pressure hydrogen distribution networks • RTP spoolable pipes are currently limited to a maximum internal diameter of between 6” to 10” and are therefore less useful as transmission pipes • Producers of RTP systems are SoluForce in The Netherlands and Fibron Pipe in the UK || Hydrogen Barrier Coatings for Gas Network Assets | Show & Tell Webinar New Line Pipe Materials Project Findings – State-of-the-art in FRP Pipes
- 54. 54 Summary & Next Steps • Glass reinforced epoxy (GRE) identified as most suitable non-metallic line pipe material, however the following challenges exist before this technology can see widespread adoption: - Validation of the performance of large-diameter GRE in high-pressure H2 at (>600 mm, > 50 bar) - Joining technologies for H2 applications - Technologies to further reduce H2 permeability of GRE - “Hearts & Minds” exercise to persuade industry of advantages of non-steel pipes – Stakeholder map generated - Development of industry-recognised standards and training (e.g. design methodologies, joining, maintenance and repair) || Hydrogen Barrier Coatings for Gas Network Assets | Show & Tell Webinar New Line Pipe Materials Conclusions & Future Work Stakeholder map for adoption of non-metallic line pipe

- 59. DNV © 19 MAY 2022 The problem the project is seeking to address • The hydrogen networks are able to contribute to the Challenge 4: Heat • Hydrogen flowing to consumers would have to increase a little over 3 times for an 100% hydrogen network, compared to natural gas. • Increase flow = increased velocity • Gas velocity constraint(s) for hydrogen, applied at the design stage, need to be identified - will impact directly onto the levels of capital investment. • Currently, IGEM standards specify: • 20 m/s to avoid debris impacting erosion and other issues • 40 m/s is assumed where the pipe assets are assumed to be clean. Other factors such a noise or vibration may also constrain the design velocity of gas in the system. • Hydrogen has different properties to natural gas – not known if debris may be picked up to the same degree or if any other factor will limit velocity 59
