Ireland is performing exceptionally well in our capability to produce green electricity, through wind in particular. With almost 400 windfarms on the Island of Ireland, we know that wind energy alone has the capacity to power all of the homes in Ireland. In 2022, we have been producing more energy though wind than ever before. Ireland is also making large steps in the advancement of Hydrogen and solar technology.

As we look towards these greener, renewable alternatives to try to decarbonise our electricity supply, we must also remember that electricity is only half of the story.

Ireland is currently the worst in Europe for producing renewable heat and according to the International Energy Agency, heat accounts for almost 50% of our energy use and about 40% of our global emissions globally.

Why is the decarbonising of heat so important?


According to the SEAI (Sustainable Energy Authority of Ireland), heat accounts for almost 33% of our energy use and about 25% of our carbon emissions.

The need to deal with the decarbonisation of heat (through electrification) is becoming more and more obvious as industries (dairy in particular) are struggling to feed the energy supply they need for their operations.

Astatine Ltd, along with other major suppliers across the country are committed to deploying one of the most economic and practical ways to meet Ireland’s decarbonisation targets  – by the widespread installation of heat pumps across our industries.

Industrial scale heat pumps are widely used across Europe with almost 20,000 installations per year. The International Energy Agency found that the most common installations occur in the food and beverage sector, with dairy being the most common application within that sector.


Considering Food & Beverage is Ireland’s largest consumer of energy across all of our industry, industrial heat pumps could offer a very quick win in reducing Ireland’s carbon footprint within the dairy industry.


This is recognised by Irish policymaking with SEAI recently publishing a National Heat Study which concluded that heat pumps are a key solution for industrial heat less than 200°C and so converting the dairy industry to this technology, quickly and at scale is one of the key solutions to tackle the rising costs and spiralling CO2 emissions.

With the technology now available to deploy solutions quickly and at scale, Astatine Ltd are committed to working with the dairy sector to convert their business to a more efficient, seamless operation, saving the significant costs and dramatically reducing their CO2 emissions.

The benefits of Heat Pumps within the Dairy Industry:

  • Heat Pump Technology can deliver up to a 100% reduction in onsite fossil fuel usage and CO2 emissions.
  • The technology can produce energy savings of up to 65%
  • A solution delivered at scale can typically provide 400% efficiency gains compared to a traditional heating system
  • Our (Astatine Ltd) experience indicates that sites can expect paybacks for 2 to 3 years
  • Projects can be delivered with no upfront costs
