Hogan's Cider is a cider maker that has been brewing since 2005. Nestled in the heart of the Warwickshire countryside, Hogan's uses expertly grown cider apples and pears from farms in Herefordshire. Allen Hogan started cider making as a hobby in the mid 1980's and after years of perfecting the process, started selling his cider at farmers markets and is now stocked worldwide. Now producing around 600,000 litres a year, energy consumption has increased alongside production volumes.
The ATETA programme offered Hogan's Cider a unique opportunity to benefit from external expertise to assess the business’ energy consumption. Hogan's uses re-fillable kegs to deliver their products to bars and pubs across the country allowing a product life of up to 20 years. The kegs require a thorough cleaning and sterilisation process on their return. This process is particularly water and heat intensive to ensure the kegs are cleaned to the required standard, or higher.
ATETA identified an opportunity to conserve some of the wasted thermal energy from this sterilisation process. There are two waste pipes which eject the water after it has been heated and used. ATETA’s analysis found that using a heat exchanger, the waste hot water could be recycled
to improve the thermal efficiency of heating the fresh hot water. As a result of this system, the process can capture around 10°C resulting in a reduced energy requirement. The team were able to use an infrared thermometer and record clear improvements in the heat lost. Without the ATETA programme, Hogan's would not have considered the implementation of this system and would not be benefitting from improved energy efficiency.
“It was good to have them visit, we really value the consultant’s insight. They actually established that we had waste, and that we should be able to capture heat”
After learning from ATETA Hogan's realises there is still more work to be done. This keg washing system has a second waste system which could also be harnessed to improve its efficiency further. Additionally, the company is considering the possibility of installing a solar panel array to power the system, instead of relying on mains electricity. The business is also considering how it can improve the sustainability of its supply chain.
These ideas are important for the Hogan's, which is highly motivated to improve their green credentials. The hospitality industry faces the challenge of improving energy efficiency, and ATLCTA has enabled Hogan’s to be one of company’s trying to make a difference.
