Calor leads on sustainable grain drying solutions, helping farmers make the switch to 100% renewable energy.

23/10/2025 4 min

Grain drying plays a vital role in preserving crop quality and extending the storage life of harvested crops in the agricultural sector. However, in recent years the traditional use of diesel in grain drying processes has raised environmental concerns and highlighted operational inefficiencies. 

Calor is committed to playing its part to support farmers to transition to more sustainable energy solutions. The first step for many farmers is the move from oil fired grain dryers to liquefied petroleum gas (LPG) powered burners for their grain drying equipment. LPG powered grain dryers offer faster drying times in comparison to other higher carbon fossil fuels. By switching to Calor LPG farmers can adopt a more sustainable and efficient approach to drying their crops, with the further opportunity to seamlessly switch to a 100% renewable fuel – Calor BioLPG.

A practical and easy solution

This solution supports farmers to manage their harvests efficiently and reduce the risk of crop spoilage. The improved efficiency can be particularly beneficial during periods of bad weather and when time-sensitive harvesting is needed. The Calor gas powered systems also provide precise temperature control, allowing farmers to optimise drying conditions for different varieties of grain. Consistent and uniform drying temperatures contribute to higher quality grain with less risk of over-drying or under-drying, resulting in reduced waste and better marketable yields. 

A further advantage of LPG is that due to how it is stored, there is little risk of fuel theft, spillage or tainting of produce. Also, as a cleaner burning fuel, there is a much reduced possibility of water ingress or fuel sediment contaminating the grain drying process.

A seamless switch to renewable energy

Calor’s renewable gas, BioLPG, is chemically identical to conventional LPG, and importantly this allows farmers to easily incorporate renewable energy without the need for modifying existing equipment if they are currently using an LPG powered system. Switching to Calor BioLPG can lower emissions by up to 80%* compared to conventional LPG. Calor also offers a variety of BioLPG blends, ensuring farmers can choose a supply option that best fits their own circumstances, location and budget. 

LPG and BioLPG can also lead to significant long-term cost savings, as a cleaner-burning fuel reduces the need for maintenance, minimises downtime for repairs, and enables quicker, more targeted drying, all of which can provide farmers with financial advantages over time.  

The Sheridan family farm, based in the Boyne Valley in County Meath, has experienced the extensive benefits of using LPG for grain drying since they switched from oil to Calor LPG, and more recently to BioLPG. The Sheridan family run over 1,800 acres including grain and potato. 

Commenting on their transition to Calor BioLPG, Mark Sheridan said: “Initially switching to Calor’s LPG was a real gamechanger in terms of reduced maintenance and more efficient drying. We are committed to looking at ways to improve our sustainability, and we were delighted with this opportunity to switch to BioLPG. The switchover was completely seamless with absolutely no downtime. This gave us a chance to opt for a more sustainable option this grain drying season and for the years to come.”

Oliver Kenny, Chief Commercial Officer, Calor commented: “At Calor, we understand that all agribusinesses have different needs. Our team of highly skilled experts who work with our agribusiness and farm customers strive to give hands on and technical support to ensure that our customer’s energy needs are met and closely managed. Calor’s BioLPG renewable gas option provides farmers with a flexible energy solution that allows them to further reduce their environmental footprint and make significant carbon savings over time.”
