The UK government is moving to bolster its supply of carbon dioxide (CO2) with a £100 million investment to reopen a shuttered plant on Teesside, a move prompted by growing concerns that escalating geopolitical tensions in the Middle East could disrupt the flow of this critical industrial gas. The decision, announced Thursday by Business Secretary Peter Kyle, underscores the fragility of supply chains and the potential for international events to ripple through seemingly unrelated sectors of the British economy.
CO2 isn’t just the fizz in your soda. It’s a vital component in a surprisingly wide range of industries, from food processing and healthcare to nuclear power and animal welfare. A shortage could have significant consequences for British consumers and businesses alike. The Ensus plant, which was idled last September, produces CO2 as a byproduct of creating bioethanol, a renewable fuel source. Its reopening is intended to provide a crucial buffer against potential disruptions, particularly as the situation in Iran remains volatile.
A Complex Chain of Events Leads to Reopening
The story of the Ensus plant’s closure and subsequent planned reopening is a complex one, tied to post-Brexit trade deals and shifting global energy dynamics. The plant was initially mothballed after a trade agreement brokered between then-Prime Minister Keir Starmer and former U.S. President Donald Trump reduced tariffs on bioethanol imports from the United States. This influx of cheaper American bioethanol undercut the competitiveness of Ensus, leading to the suspension of operations. Now, an unnamed UK government official, speaking to the Financial Times, has highlighted the irony of the situation: “The irony is that the plant was shut because of a deal with Trump and now it’s reopening because of Trump’s war in Iran.”
The current concern stems from the potential for the conflict in Iran to disrupt energy markets and, the production of CO2. Fertilizer production, a major source of CO2, is energy-intensive. Rising gas prices, exacerbated by geopolitical instability, can make fertilizer production less viable, leading to a reduction in CO2 output. Disruptions in European fertilizer production and unplanned maintenance at other CO2 plants across the continent have added to the anxieties surrounding supply.
CO2: More Than Just Bubbles
The importance of CO2 often goes unnoticed by the general public. Beyond carbonating beverages and preserving food, it plays a critical role in several essential services. In the healthcare sector, CO2 is used in keyhole surgery and for cryotherapy. The food industry relies on it for packaging, extending shelf life and stunning animals for slaughter. Even the nuclear industry utilizes CO2 in certain cooling processes. Grant Pearson, chair of Ensus UK, emphasized the broad impact, stating that the government support would strengthen “the broader Teesside manufacturing economy and the UK’s resilience in relation to biogenic CO2 supplies,” adding that the gas is “vital to food and drinks companies, as well as being important to hospitals, abattoirs and the nuclear industry.”
The UK experienced a significant CO2 crisis in 2021, triggered by soaring wholesale gas prices following the easing of pandemic restrictions. This led to concerns about meat processing and beer production, ultimately requiring a government bailout of CF Fertilisers, another Teesside-based CO2 producer. A similar situation unfolded in 2018, when a global shortage of CO2 forced Warburtons, a major British bakery, to temporarily halt crumpet production due to a lack of packaging gas. Heineken also temporarily suspended production during that period.
Government Intervention and Economic Forecasts
The Department for Business and Trade announced the reopening of the Ensus plant will be supported by approximately £100 million in government funding for an initial three-month period, with the hope of establishing a longer-term operational footing. Business Secretary Peter Kyle stated that the government “will always do what’s needed to ensure resilience and protect British businesses from the worst impacts of global uncertainty,” emphasizing the swift action taken to safeguard critical supply chains.
The move comes as energy consultancy Cornwall Insight predicts significant increases in energy costs for businesses. They forecast potential electricity bill increases of 10-30% and gas bill hikes of 25-80%, further highlighting the vulnerability of UK industries to external shocks. The reopening of Ensus is therefore seen as part of a broader government strategy to secure access to critical industrial resources during times of global instability.
The Ensus plant, operational since 2010, converts wheat into bioethanol through distillation and fermentation, with CO2 as a valuable byproduct alongside high-protein animal feed. The facility, headquartered in Middlesbrough, currently employs around 100 people, and its reopening will provide a boost to the local economy.
The situation remains fluid, and the long-term success of the Ensus plant’s reopening will depend on the evolution of the conflict in Iran and the broader global energy landscape. The government has indicated this is part of a wider effort to ensure supply chain resilience, but the incident underscores the interconnectedness of global markets and the potential for geopolitical events to have far-reaching economic consequences.
The Department for Business and Trade is expected to provide further updates on the Ensus plant’s operational status and the broader CO2 supply situation in the coming weeks. Readers are encouraged to share their thoughts and concerns in the comments below.
