As you know, the United Kingdom is planning to achieve ambitious climate targets by 2050, mainly through clean energy, hydrogen, carbon capture, and significant efforts toward net-zero emissions. But staggeringly, the UK’s net-zero goals are at risk as water shortages intensify (as revealed by a recent study). In simple terms, some of the green-energy and decarbonization projects considered are very water-intensive, and water is becoming scarce. If water supplies are insufficient to meet demand, many of those plans will be delayed or even fail.
It’s not just a problem of the UK — it is a global call to the reality of how climate goals and scarcities of resources are interrelated.
Water Demand vs. Supply
Through the use of water supplies, the demand for them has increased. The UK’s existing water company region, as indicated in the study, shows how much decarbonisation is going to dramatically increase water demand.
A summary of this is below:
| What | Before the decarbonisation | With planned carbon-capture and hydrogen projects by 2050 |
|---|---|---|
| Water demand for industry/energy | Moderate, using existing methods | Additional demand reaching about 860 million litres/day |
| Forecast water supply gap(some regions) | Manageable or somewhat stressed | Shortfall for water supplies in regions like Anglian Water/United Utilities as early as 2030-2040 |
| Total demand for water (public and industry combined) | Under the supply limitation | Significant risk of water shortage |
In conclusion, the amount of extra water needed to create either hydrogen or carbon capture technology to meet net-zero will not be affordable or readily available to be used when it is needed.

Why is Water Shortage Interfering with the UK’s Net-Zero Ambitions
Here are the key reasons:
- Water demand of carbon-free tech — To produce hydrogen, capture CO2, and many low-carbon technologies requires water during the process. The new study demonstrates that the demand could reach several million liters per day by 2050.
- Regional water deficits at a glance — The shortage of water is estimated for certain areas within the next few years (as soon as 2030).
- Industrial-use projection is missing in water planning —Current water supply plans are far from fully considering the demand of the future industries, as well as decarbonization. The difference between these two creates a blind spot when net-zero infrastructure is being scaled.
- Competition between domestic needs & industrial water demand —The water that is available for the supply must serve households, agriculture, industry, as well as the new green projects — under a condition of scarcity, someone is forced to pay the price.

What This Means for Climate Targets & Society
UK’s net zero goals are at risk as water shortages intensify. Scientists caution that this may weaken the overall efforts directed towards a sustainable future.
- Net-zero by 2050 may get delayed: If projects that are based on hydrogen and carbon-capturing do not get the water that they require, then the consequent rollout of these projects might be postponed or canceled. Thus, indirectly reducing the UK’s capability to lower greenhouse gas emissions.
- Higher cost & resource pressure: Water scarcity may result in the government or companies having to install expensive infrastructure (e.g., desalination, water recycling) to meet demand.
- Strain on households and penalized services: Water shortages not only impact the industries, but they also put the most basic water supply for citizens at risk.
- Potential economic setbacks: Water scarcity is already a major risk factor for housing, infrastructure, and industry growth. With the risk of net-zero projects, economic growth and green-job plans may be negatively affected.

What Must Be Done: Balancing Water and Net Zero
Here is what the experts suggest if the UK is still willing to pursue net-zero while ensuring water security:
- Improved water resource management: Water companies and regulators should anticipate the future industrial water demand (not only that of households) and, accordingly, approve or decline green projects.
- Water saving & water cycle: Industries should be encouraged to use water-efficient technology, install water recycling in their processes, etc. Where most water is required, for example, cooling should be done by non-potable water.
- Desalination & new fresh supply: If the area is on the coast, desalination plants can be the solution that will free up fresh water for other uses from the reservoir.
- Sharing of water resources and the use of smart meters: Regions that have water in excess can provide water to areas that suffer from shortages, and thus, planning and transparency in data become important.
- Consideration of all factors: nature + resources + climate plan together: The goals for climate neutrality have to take into account the limits of resources and cannot plan for climate without taking into account water scarcity.

Quick Takeaways
The fact that the UK’s net-zero goals are at risk as water shortages intensify is very worrying.
- One of the major contributors to a low-carbon energy future is the enormous water demand for projects such as hydrogen and carbon capture. The study predicts that demand could reach approximately 860 million liters per day in 2050.
- Several regions of the UK are already on their way to water deficits.
- Smart planning (water recycling, desalination, efficient usage) is necessary for the success of climate ambitions.
- Water scarcity may slow down not only the green-energy transition but also basic water security for people.

Final Thoughts
UK’s net zero goals are at risk as water shortages intensify; it is not a dramatized exaggeration – it’s a serious wake-up call. The UK, while striving for a low-carbon future, must not forget one of its essential resources: water.
Green energy and climate ambitions will be of no use if the basics cannot be secured. Water scarcity is a threat not only to the success of net-zero but to the regular living of people and future growth as well.
Therefore, there is still a chance for a sustainable, water-secure, net-zero future if the decision-makers, water companies, and climate planners act wisely by integrating water management with decarbonisation. If not, the water shortage might just take those hopes with it.

FAQs
Q1. Why do hydrogen and carbon-capture projects need so much water?
The production of hydrogen (especially blue/green hydrogen) and carbon-capturing activities require water for cooling, chemical processes, and cleaning. The 2025 study reveals that water demand can increase by hundreds of millions of liters per day if planned projects are taken into account.
Q2. Are all regions of the UK affected equally by water shortage risks?
Not at all. The forecast for water company areas is that some of them, e.g., those which are supplied by Anglian Water or United Utilities, will see a shortage of water at the earliest (some even by 2030–2040) if decarbonization water demand is added.
Q3. Can the UK still achieve net zero despite water challenges?
Yeah, but only if resource planning takes a turn for the better. This means that water resource management should be integrated with decarbonisation plans: by making water more efficient, by investing in recycling/desalination, by rethinking water usage and by coordinating green-energy rollout with real water-availability data.
