Quick Summary:
- The UK Government’s Industrial Decarbonisation Strategy (IDS), published in 2021 and updated through subsequent Net Zero pathway documents, sets legally binding targets for heavy industry sectors — including chemicals, iron and steel, cement, glass, and paper — to achieve deep decarbonisation by 2035 (for government-procured products) and by 2050 (for the broader industrial base), with a critical milestone of a 67% reduction in industrial emissions by 2035 compared to 2018 levels.
- For valve procurement engineers and plant operators, the industrial decarbonisation agenda directly affects valve specification in at least three ways: the rapid growth of industrial electrification (replacement of steam-heated processes with electrically heated alternatives) changes the pressure-temperature profiles of process systems; the adoption of hydrogen co-firing and hydrogen carrier fuels changes the fluid service conditions; and fugitive emission reduction targets (methane and VOC leakage from valve stems, flanges, and fittings) are becoming a quantified KPI on industrial sites subject to Environmental Impact Assessment and permit conditions.
- The most immediate procurement implication of the UK Industrial Decarbonisation Strategy for the valve industry is the requirement for Whole Life Cost (WLC) assessment in public sector and regulated industry procurement — valves procured on first-cost-only criteria in decarbonising industries will increasingly be challenged to demonstrate their through-life performance on fugitive emissions, energy efficiency (pressure drop), and end-of-life recyclability, as procurement frameworks align with the UK Government’s Procurement Policy Note 06/21 on social value and sustainability.
The UK Industrial Decarbonisation Strategy: Context for the Valve Industry
The UK Government’s Industrial Decarbonisation Strategy, published in March 2021 by the Department for Business, Energy and Industrial Strategy (BEIS), sets out the framework for decarbonising UK heavy industry — defined as the chemical, iron and steel, cement and lime, glass, ceramics, and paper and pulp sectors. These sectors collectively account for approximately 15% of UK territorial greenhouse gas emissions, with a further significant proportion coming from indirect emissions (electricity consumption and process heat from fossil fuels).
The strategy is built around three pillars: fuel switching (replacing fossil fuel combustion with hydrogen, electrification, or other low-carbon alternatives); carbon capture and storage (for process emissions that cannot be eliminated through fuel switching); and energy efficiency improvement (reducing the energy intensity of industrial processes). Each of these pillars has direct implications for the types of valves required in industrial process systems, the service conditions those valves must handle, and the performance standards they must meet.
For valve engineers and procurement specialists, the strategy is not an abstract policy document — it is a forecast of the industrial capital expenditure programme over the next 15–25 years. Sectors that are subject to the strategy will be making substantial investments in new process equipment, retrofit modifications to existing plant, and replacement of fossil fuel-fired utilities with electrified or hydrogen-fuelled alternatives. These investments will generate demand for valve products and engineering services across a range of new and modified service conditions.
Industrial Electrification: Changing Process Conditions
The replacement of steam-heated and gas-fired process heating with electrically powered alternatives — electric furnaces, plasma heaters, infrared heat systems, heat pumps — changes the pressure-temperature profiles of industrial process systems in ways that affect valve specification.
In a conventional steam-heated chemical process, the heating medium is steam at a defined saturation pressure and temperature (say 10 bar saturated steam at 184°C). The process control valves on steam supply lines are specified for steam service at this condition — the valve material, trim design, and actuator sizing are all appropriate for this particular pressure-temperature combination. When the same process is converted to electrical heating — for example, using an electric immersion heater or a Joule heating element — the steam supply system is no longer required, and the associated steam control valves become redundant. New valves are needed for the electrical heating system’s thermal fluid distribution, or for the high-voltage electrical connections (which do not use valves, but the supporting cooling and safety systems do).
More significant for valve engineering is the shift in industrial heat pump and high-temperature heat pump systems. Heat pumps using CO₂ as a refrigerant (achieving hot-side delivery temperatures up to 120°C with a transcritical cycle) or high-temperature heat pumps using propane, R-1233zd, or bespoke refrigerants (delivering up to 160°C) represent a growing market for valves in refrigerant service at moderate pressures — a service envelope that differs significantly from both conventional refrigeration valve service (which is well-established but typically at lower temperatures) and conventional process valve service (which handles higher temperatures but different fluids).
Hydrogen Co-Firing and Valve Implications
Hydrogen co-firing — replacing a proportion of natural gas with hydrogen in industrial furnaces, boilers, and process heaters — is a near-term decarbonisation strategy that is technically achievable with existing combustion equipment at hydrogen fractions up to approximately 20% by volume (often quoted as 20% Hv, hydrogen by volume). At higher fractions, combustion equipment modifications may be required.
For valve engineers, hydrogen co-firing at low fractions (below 20% by volume) in existing natural gas pipework generally does not require valve replacement — the hydrogen embrittlement risk at these partial pressures of hydrogen in a predominantly methane stream is manageable with standard carbon steel valve body materials, and the piping pressure ratings are unchanged. The critical check is the elastomeric seal materials: some elastomers (particularly NBR) are more susceptible to hydrogen permeation and swell than others (EPDM, Viton), and seal performance under prolonged exposure to the hydrogen-enriched gas mixture should be verified against manufacturer data for the specific elastomer grades used in the installed valve population.
At higher hydrogen fractions (above 20–30% by volume), and particularly for new infrastructure designed for high-blend or pure hydrogen service, the hydrogen embrittlement considerations discussed in earlier posts on hydrogen service apply in full. High-strength steels must be avoided; carbon equivalent must be controlled; elastomeric seals must be rapid-decompression qualified; and the valve specification must reference the appropriate hydrogen service standards (ASME B31.12, ISO 15649 for hydrogen piping).
Fugitive Emission Reduction: From Best Practice to KPI
Fugitive emissions from valve stems, flanges, and other pressurised connections have been recognised as a significant source of methane and VOC emissions for decades. The US EPA Leak Detection and Repair (LDAR) programme, the European EPER and E-PRTR emission inventories, and the UK’s National Atmospheric Emissions Inventory all identify fugitive emissions from process plant as a measurable and reportable emission category.
What is changing under the industrial decarbonisation agenda is the regulatory and commercial pressure to reduce these emissions, not merely report them. The UK Government’s Methane Strategy (2022), the Global Methane Pledge (pledging a 30% reduction in global methane emissions from 2020 levels by 2030), and the increasing integration of fugitive emission data into Environmental Permits (under the Environmental Permitting Regulations 2010 in England and Wales) are collectively moving methane from a reported-but-tolerated emission category to a regulated-and-enforced one.
For valve procurement engineers, this means that the ISO 15848-1 Class BH or API 641 fugitive emission specification — previously a “best practice” specification applied on a project-by-project basis for premium valves in critical service — is becoming a baseline specification for any valve in natural gas, methane, or VOC service at plants subject to methane emission reduction commitments. The incremental cost of specifying low-emission packing and live-loaded glands on new valve purchases is small relative to the cost of either non-compliance with permit conditions or the reputational and commercial cost of being identified as a high-emitter in an industry that is increasingly scrutinised for its methane footprint.
Carbon Capture Valve Procurement: Emerging Standards
The UK’s carbon capture, utilisation and storage (CCUS) programme — centred on the East Coast Cluster (Humber and Teesside) and the HyNet North West cluster — represents the largest single piece of new industrial infrastructure investment in the UK since North Sea development. The CO₂ transport and storage pipelines, onshore gathering networks, capture plant equipment, and injection wells each require valves specified for CO₂ service — and, as discussed in our energy transition article, CO₂ service presents specification challenges that are materially different from standard oil and gas valve service.
The valve procurement standards for CCUS are still developing. The UK’s CCUS programme has adopted the DNV CO₂QUAL specification framework for CO₂ pipeline materials qualification, which includes valve body and seal materials assessment. ISO 23936-2 (non-metallic materials in CO₂ service) and DNVGL-RP-F104 (design and operation of CO₂ pipelines) are the primary technical references, supplemented by project-specific technical requirements that reflect the specific CO₂ stream composition (which varies by capture source — cement kiln CO₂ streams differ from power station post-combustion capture streams in their contaminant content).
For valve procurement engineers on CCUS projects, the key specification requirements beyond standard pipeline valve practice are: CO₂-specific elastomeric seal qualification (rapid decompression testing in CO₂ per ISO 23936-2); CO₂-specific corrosion assessment for wet CO₂ service (which may require corrosion-resistant alloy trim or bodies in sections of the pipeline where water condensation is credible); and attention to Joule-Thomson cooling at valve trim under depressurisation conditions (which can create extremely low temperatures — below -50°C — that require trim materials qualified for cryogenic temperatures).
Whole Life Cost Procurement and Sustainability Reporting
The UK Government’s Procurement Policy Note 06/21 (Social Value in Government Procurement, now embedded in procurement regulations for public sector buyers) requires that social value — including environmental sustainability — is assessed as a weighting in procurement evaluation. While this applies directly only to public sector procurement, the policy is increasingly influencing procurement practices across regulated industries (water, energy, and transport infrastructure) and major industrial operators who are subject to Environmental, Social, and Governance (ESG) reporting requirements.
For valve procurement in decarbonising industries, whole life cost assessment typically includes: first cost; installation cost; expected maintenance frequency and cost (based on the valve’s service conditions and the specified maintenance strategy); energy cost from pressure drop across the valve over its service life (a full-bore ball valve in a high-flow service may consume significantly less pumping energy over a 25-year life than a globe valve with higher Cv requirement); fugitive emission cost (quantified at a carbon price and deducted from the expected emission saving of low-emission versus standard packing specifications); and end-of-life cost (including material recyclability — stainless steel bodies have high scrap value; PTFE and elastomeric trim components do not).
This is not merely an academic exercise. For large-scale valve procurement on decarbonising industrial sites (where a single project may involve hundreds of valves with a total purchase value of several million pounds), the difference in whole life cost between competing specifications can be substantial — and the procurement authority has a legitimate interest in understanding those whole life costs, not just the purchase order price.
Practical Implications for the UK Valve Supply Chain
The industrial decarbonisation agenda creates both opportunities and demands for the UK valve supply chain. The opportunity is clear: decarbonisation projects require new valve procurement for hydrogen infrastructure, CCUS pipelines, electrification projects, and upgraded process plant. These projects are at various stages of development and will generate procurement activity over the next 5–20 years.
The demand is equally clear: customers on decarbonisation projects are increasingly expecting their valve suppliers to demonstrate technical capability in hydrogen service, CO₂ service, and cryogenic LNG service — not just to supply standard oil and gas valve products. Suppliers who have invested in product qualification testing for these new service conditions, and who can provide the specific technical documentation (CO₂-qualified seal test reports, hydrogen embrittlement assessment results, cryogenic test certificates) that project specifications require, will be better positioned to win decarbonisation project valve supply contracts than those who cannot.
The association news context here is that organisations including the British Valve and Actuator Association (BVAA), the Energy Industries Council (EIC), and the British Standards Institution (BSI) are actively working on the standards and guidance frameworks that will support the UK’s industrial decarbonisation programme. Engineers and procurement specialists who engage with these organisations — through working group participation, attendance at industry events, and access to the developing standards and guidance — will be better equipped to specify correctly and procure effectively for the next decade of decarbonisation projects.
Summary
The UK Industrial Decarbonisation Strategy is reshaping the valve and flow control landscape — not immediately, not overnight, but inexorably. Hydrogen co-firing, CCUS infrastructure, industrial electrification, and fugitive emission reduction are translating into changed service conditions, new qualification requirements, and evolving procurement standards that the valve industry must engage with now, not when the first project specifications arrive. Valve engineers who understand these drivers, and procurement specialists who can integrate sustainability and whole life cost into their purchasing decisions, will be the professionals best equipped to serve their industries through the energy transition. The fundamentals of valve engineering do not change — but the fluids, the conditions, and the requirements are shifting, and our specifications must shift with them.
