Distillery Pioneers World’s First Low-Carbon Whisky Production
A south of Scotland distillery says it has developed a novel method to produce the high-temperature steam used in whisky making. Annandale Distillery in Dumfries and Galloway aims to pioneer low-carbon whisky production using locally generated green electricity.
How the system works
The project stores renewable electricity as heat rather than in batteries. Cold air is pushed through a large heat store, raising temperatures to very high levels.
The hot air then feeds a conventional-style boiler to create steam for distillation. The distillery describes the approach as a means to cut fossil-fuel use in whisky production.
Temperature claims and operation
The team has cited a headline figure of 1,200C for the heat store. Engineers involved describe the heat store reaching around 500–600C when air is passed through it.
Either way, the system delivers the high-pressure, high-temperature steam that distillation requires.
Partners and technical details
The scheme was developed with clean-heat specialist Exergy 3 and boiler-maker Cochran Ltd. Annandale operates three storage modules with a combined 30 MWh capacity.
Those modules supply hot air to a 3 MW Cochran boiler. The boiler converts that air into green steam at 10 bar pressure.
Project engineers say the installation’s physical footprint is no larger than an average garage. It also needs only modest additional infrastructure.
Motivation, costs and constraints
Co-founder Professor David Thomson called the work a global first when speaking to Filmogaz.com. He said the system allows whisky to be produced with a much lower carbon impact.
However, electricity prices remain a major constraint. The distillery reports European electricity costs are high, and green levies increase bills despite cheap off-peak power.
Wider decarbonisation measures
Annandale’s plan extends beyond steam. The site now bottles and matures spirit onsite to cut road miles. Electric vehicles are being introduced where possible.
The team is also testing reuse options for spent grain and captured carbon dioxide. These measures support a broader shift toward low-carbon whisky production.
Industry context
Scotland’s whisky sector has set a goal to fully decarbonise operations by 2030. Producers have trialled electric lorries for short-haul moves and alternative packaging like paper bottles.
Glenmorangie has even built an oyster reef on the Dornoch Firth to help filter effluent. Industrial processes such as steam production account for about 13% of Scotland’s greenhouse gas emissions.
History and recent milestones
Annandale closed in 1919 and later reopened after a major restoration this century. The distillery was officially reopened by the Princess Royal in 2015.
In 2024 the owners celebrated their first 10-year-old single malt since operations resumed. The project positions Annandale among distillery pioneers exploring sustainable production.
