Recent instability in the Middle East has once again triggered sharp movements in global energy markets, pushing European gas prices significantly higher in the space of just a few days. 

While the geopolitical developments themselves are unfolding thousands of miles from the UK, the market reaction illustrates a familiar reality: the UK remains deeply exposed to international gas market volatility.

Over the past week, the European gas benchmark (Dutch TTF) surged from the low €30s to more than €60/MWh as traders reacted to potential disruption across global LNG supply routes. A major factor behind the spike has been renewed uncertainty surrounding shipping through the Strait of Hormuz - a critical corridor for global liquefied natural gas transport.

Although the UK does not rely directly on these shipments, European markets do and because Britain purchases gas within the same interconnected trading system, disruptions anywhere in the global supply chain quickly translate into higher wholesale prices for UK consumers.

Events like these serve as a reminder that energy markets are nowhere near national, that gas prices in the UK can be shaped as much by international shipping routes and geopolitical risk as by domestic supply and demand.

The UK’s Structural Gas Exposure

Despite significant progress in renewable electricity generation, the UK economy remains structurally reliant on natural gas.

Gas continues to play a major role in:

• domestic heating
• industrial heat and manufacturing processes
• electricity system balancing during periods of low renewable output

As a result, even when renewable generation performs strongly, the UK remains tied to global gas markets for large portions of its energy demand.

This means that when LNG markets tighten or supply disruptions occur, the final marginal cargoes entering Europe - often purchased at volatile spot prices - set the wholesale price for the entire system.

In practical terms, this is why geopolitical events can still drive rapid price increases for UK households and industry.

The Role of Domestic Renewable Gas

One of the most practical ways to reduce this exposure lies in expanding domestic renewable gas production.

Today, the UK produces roughly 7–8 TWh of biomethane annually, primarily from approximately 750+ anaerobic digestion plants processing agricultural residues, food waste and organic by-products; this is enough to supply between 350,000 and 600,000 homes with renewable gas.

However, studies across the sector suggest that the UK’s sustainable biomethane potential could reach 20–30 TWh per year by the early 2030s and 120 TWh per year by 2050, drawing on a wide range of feedstocks including manures, crop residues, food waste streams and industrial organic by-products.

Importantly, achieving this scale does not necessarily mean building an entirely new fleet of facilities. Much of the potential lies in:

• upgrading existing AD plants to produce grid-quality biomethane
• consolidating underutilised feedstock streams
• developing larger, more efficient next-generation facilities

As a result, the current level of production likely represents closer to 5–10% of the UK’s long-term biomethane potential, rather than the 25% that headline numbers might suggest.

A Strategic Complement to Renewable Electricity

Renewable electricity generation has already played a major role in reducing the UK’s exposure to fossil fuels, particularly through the rapid expansion of offshore wind.

However, electricity generation is only one part of the national energy system, where heating demand, industrial energy use, and seasonal balancing requirements remain more difficult to electrify quickly.

This is where biomethane plays a particularly valuable role.

Unlike intermittent renewable electricity, biomethane is:

• fully dispatchable
• storable within the existing gas network
• compatible with current heating and industrial infrastructure

In effect, renewable electricity reduces the UK’s reliance on gas for power generation, while biomethane reduces reliance on imported gas within the wider energy system.

Together, these technologies create a more balanced and resilient energy mix.

Energy Security Through Domestic Infrastructure

Events in global energy markets this week highlight a broader strategic lesson: energy security increasingly depends on the scale and diversity of domestic infrastructure.

While the UK cannot insulate itself completely from global events, expanding home-grown energy production - across renewables, renewable gas and supporting infrastructure - can significantly reduce the impact of external shocks.

For sectors working across energy infrastructure and project delivery, this reinforces the importance of continuing to develop practical, scalable solutions that strengthen the UK’s long-term resilience.

Because, when international markets become volatile, the value of reliable domestic energy sources becomes immediately clear.
