Hybrid System, Heat Pump, solar PV, cooling and hot water


Cairngorm Brewery




Aviemore, Scotland


Cairngorm Brewery, located in the heart of the Scottish Highlands, is a renowned craft brewery known for its exceptional range of traditional and innovative beers. With a commitment to quality and sustainability, Cairngorm Brewery has established itself as a prominent player in the Scottish brewing industry.

Cairngorm Brewery faced the challenge of reducing their carbon footprint and optimising energy consumption while maintaining the high standards of beer production. They sought a comprehensive solution that would integrate multiple renewable energy technologies to meet their heating, cooling, and hot water requirements.

Our Solution

Biosus Energy, designed and is implementing a hybrid system that incorporates heat pumps, solar energy, cooling and hot water technologies. This tailored solution is aimed to maximise energy efficiency, minimise environmental impact, and enhance the overall operational performance of the brewery.

Key Features

  • Heat Pumps: Biosus Energy is installing a high-efficiency heat pump at Cairngorm Brewery to harness ambient heat from the conditioning and cooling of beer, in doing so, cool beer but also provide hot water for mashing. The heat pump efficiently transfers heat energy, reducing the reliance on traditional heating and cooling methods significantly lowering energy consumption.

  • Solar Energy: A solar photovoltaic (PV) system will be integrated into the hybrid solution, capturing clean and renewable solar energy to generate electricity. The solar PV panels will be strategically installed to optimise solar exposure, generating a portion of the brewery’s electricity needs and reducing dependency on grid-supplied power.

  • Cooling and Hot Water: Biosus Energy is implementing innovative cooling and hot water technologies to cater to Cairngorm Brewery’s specific requirements. These solutions optimised the cooling processes during the brewing and fermentation stages and ensured a reliable supply of hot water for various brewery operations.


The collaboration between Biosus Energy and Cairngorm Brewery resulted in significant benefits and positive outcomes:

  • Energy Efficiency and Cost Savings: The hybrid system, comprising heat pumps, solar energy, and tailored cooling and hot water technologies, significantly reduced energy consumption at Cairngorm Brewery. This led to substantial cost savings by minimising reliance on traditional energy sources and reducing utility bills.
  • Carbon Footprint Reduction: The integration of hybrid renewable energy technologies will help Cairngorm Brewery reduce its carbon footprint. By utilising clean energy sources such as solar power and efficient heat pumps, the brewery decreased its reliance on fossil fuels, demonstrating a commitment to environmental sustainability.

  • Operational Performance and Reliability: The hybrid system implemented by Biosus Energy enhanced the overall operational performance of Cairngorm Brewery. The optimised heating, cooling, and hot water solutions ensured consistent production processes, contributing to product quality.

  • Brand Differentiation: Cairngorm Brewery’s investment in sustainable energy solutions showcased their commitment to environmental stewardship. This positions them as a forward-thinking and environmentally conscious brewery, enhancing their brand reputation and attracting environmentally conscious customers.

The successful implementation of the hybrid system at Cairngorm Brewery will exemplify the positive impact of integrating renewable energy technologies. By leveraging heat pumps, solar energy, and tailored cooling and hot water solutions, Cairngorm Brewery will achieve energy efficiency, cost savings, and environmental sustainability.
