One of the emerging realities of the global economy is that access to reliable water is becoming almost as important as access to electricity.
Shale gas extraction and AI data centres are major examples, but a growing list of industries now require enormous quantities of water for cooling, cleaning, chemical processing, hydrogen production, or power generation. In many regions this is already influencing where new industrial investment can realistically go.
Among the biggest new water-intensive industries are semiconductor fabrication plants (“fabs”), green hydrogen production facilities, battery gigafactories, advanced chemical processing plants, carbon capture systems, and some forms of mineral refining. Semiconductor manufacturing is particularly extreme because producing advanced computer chips requires ultra-pure water in vast quantities to wash silicon wafers repeatedly during production. Modern leading-edge fabs can consume 10–20 million gallons of water per day.
This matters because AI data centres and semiconductor fabs are increasingly being built together in the same technology corridors. AI systems require huge numbers of chips, and both industries compete for the same water and electricity infrastructure. Analysts are now warning that water scarcity could become one of the main bottlenecks to future AI expansion.
Green hydrogen is another major new claimant on water supplies. Hydrogen made through electrolysis splits water into hydrogen and oxygen, meaning that large-scale hydrogen production requires both abundant electricity and significant volumes of purified water. While the direct water requirement is smaller than some heavy industries, once scaled to national energy systems the demand becomes substantial, especially in dry regions trying to develop hydrogen export economies.
Battery gigafactories are also highly water intensive. Water is used in electrode production, cooling systems, washing processes, chemical handling, humidity control, and fire suppression systems. As electric vehicle production expands globally, clusters of battery plants are increasingly concentrating around regions with dependable water supplies.
Another major emerging sector is carbon capture and industrial decarbonisation infrastructure. Carbon capture plants often require significant cooling water and steam generation. Likewise, new electric arc steel plants, synthetic fuel facilities, and some biofuel operations can place heavy stress on local water systems. Mining and critical mineral processing — especially lithium extraction and copper refining — are also becoming major water users as the energy transition accelerates.
The location implications are now becoming very significant.
For decades, industrial location decisions focused mainly on labour, transport links, taxes, and energy costs. Increasingly, water security is becoming a deciding factor. Some areas that once looked ideal for industrial expansion are now facing serious constraints because rivers, aquifers, and reservoirs are already under pressure from agriculture and population growth.
This is especially visible in the American southwest. States such as Arizona, Nevada, New Mexico, and parts of Texas attracted data centres and semiconductor projects because of cheap land and energy, but they also face chronic drought risk. Taiwan — home to some of the world’s most advanced semiconductor fabs — has repeatedly experienced drought emergencies that threatened chip production.
As a result, governments and corporations are increasingly looking toward regions with abundant freshwater resources, cooler climates, and stable electricity supplies. Parts of Scandinavia, Canada, Scotland, northern England, and some Nordic countries are becoming attractive for future AI infrastructure because cooler temperatures reduce cooling demand while water availability is more secure.
However, even water-rich regions face challenges. Large facilities can still overwhelm local infrastructure, especially if multiple projects arrive at once. Communities are beginning to resist developments that could strain reservoirs or rivers during dry periods. In some places, planners are already asking whether AI data centres or hydrogen projects should be prioritised over agriculture, housing, or public water supplies.
The industry response is increasingly focused on water recycling and closed-loop systems. Semiconductor fabs now recycle large portions of their water, while some newer AI data centres are experimenting with “zero-water” cooling systems. But these technologies add cost and complexity, meaning that water-rich regions still retain a major competitive advantage.
In effect, the world may be entering a period where water availability quietly reshapes the global industrial map. Countries with abundant freshwater, reliable power grids, and cooler climates could gain strategic advantages similar to how oil-producing nations benefited during the fossil fuel era. Meanwhile, regions already facing drought and climate stress may find it increasingly difficult to support the next generation of AI, semiconductor, hydrogen, and advanced manufacturing industries.
Scotland Could Be Good Place But The Plannng System Needs To Speed Up
wetter, cooler places such as Scotland could become increasingly attractive locations for some future industrial facilities, especially AI data centres, semiconductor support industries, hydrogen projects, and advanced manufacturing. In fact, many analysts now think climate and water availability may become strategic economic advantages over the next 20–30 years.
Scotland has several natural advantages. It has relatively abundant freshwater resources compared with many parts of southern Europe, the Middle East, India, northern China, or the American southwest. It also has a cool climate, which matters because data centres consume enormous amounts of electricity simply removing heat from servers. Cooler outside air can dramatically reduce cooling costs and water consumption.
In addition, Scotland has growing renewable energy capacity, especially offshore wind. Areas around Moray Firth, Aberdeenshire, and the Highlands are increasingly discussed as possible energy-intensive industrial hubs because they combine wind power potential, port access, and relatively low population density.
However, Scotland is far from alone. There are several other regions globally with similar or even larger advantages:
Norway and other Nordic countries already attract data centres because they combine hydropower, cool climates, and political stability.
Canada has enormous freshwater reserves and cold temperatures.
Parts of Sweden and Finland are becoming major AI and cloud infrastructure locations.
Northern parts of the United States near the Great Lakes have water advantages.
Some regions of Iceland attract facilities using geothermal and hydroelectric power.
The competition may therefore become less about simply having water, and more about having a combination of:
secure long-term water supplies,
abundant low-cost electricity,
strong fibre-optic and internet connectivity,
political stability,
engineering skills,
available land,
and fast planning approval systems.
That last point is important. Scotland has advantages, but also potential obstacles. Large industrial projects often face long planning processes, grid connection delays, transmission bottlenecks, and local opposition. Electricity grid capacity is becoming a major issue across the UK. In some areas, developers reportedly face waits of many years for high-voltage grid connections.
Another limitation is scale. Scotland has abundant rainfall, but population centres and industrial infrastructure are relatively small compared with places like Canada or Scandinavia. A few very large AI or hydrogen projects could place noticeable strain on local grids, ports, roads, and water systems unless infrastructure investment expands significantly.
There is also an emerging geopolitical angle. Countries increasingly want “sovereign” or domestic AI infrastructure and chip supply chains for security reasons. That may favour politically stable allied countries with reliable energy and water. The UK could therefore become more attractive for Western-backed projects even if operating costs are higher than in some other regions.
One particularly interesting possibility is that parts of northern Scotland could eventually market themselves as “climate-resilient industrial zones” — places where future industries can operate with lower heat stress, lower water scarcity risk, and access to renewable electricity. What was once considered a disadvantage — cooler, wetter weather far from major population centres — could become an economic asset in a hotter, more water-constrained world.
But there are still many competing locations globally, and Scotland’s success would depend heavily on infrastructure investment, planning reform, electricity transmission upgrades, and whether governments actively pursue these industries.
