Celtic Renewables

In the pursuit of sustainable and renewable energy solutions, Celtic Renewables stands out as a pioneer of innovation. Celtic Renewables are a spin-out from Edinburgh Napier University’s Biofuel Research Centre, founded in 2012 by Professor Martin Tangney, a visionary biochemist.The company has been on a mission to transform by-products of the whisky industry into advanced biofuels.

Celtic Renewables was born from Professor Tangney's commitment to finding environmentally friendly alternatives to traditional fossil fuels. The idea took shape around utilizing residues from whisky production, namely draff and pot ale, to create biofuels. With a deep understanding of biochemistry and renewable energy, Professor Tangney set out to make a significant impact on both the energy and distillery industries.

The unique aspect of Celtic Renewables' approach lies in its connection to the whisky industry. Draff, the solid residue left after mashing and fermentation, and pot ale, the liquid residue from distillation, are typically considered waste products. Celtic Renewables saw an opportunity to turn this perceived waste into a valuable resource.

Celtic Renewables' proprietary technology involves the fermentation of draff and pot ale using microorganisms. This process yields bio-butanol, an advanced biofuel with the potential to replace conventional fossil fuels in various applications, including transportation. Not only does this approach provide an alternative energy source, but it also addresses the environmental impact of industrial waste.

Celtic Renewables has celebrated remarkable achievements, making history in 2017 by fueling the world's first car with biobutanol derived from local whisky production residues. Since then, the company has demonstrated consistent growth, actively seeking investment opportunities.

The Company raised £20m+ in 2020, funding the construction and opening of the first biorefinery in Scotland at Caledon Green in 2021. This commercial processing plant, located in Grangemouth, stands as Celtic Renewables' flagship facility. It plays a pivotal role in their operations, processing by-products and residues to generate high-value sustainable biochemical products. The plant's purpose is not only to minimize waste by utilizing local industry residues but also to displace conventional petrochemicals with more environmentally friendly alternatives.

This strategic focus on large-scale production reflects Celtic Renewables' dedication to making a substantial impact on the renewable energy sector. Their continuous efforts to secure investments highlight their commitment to expanding operations and contributing to the broader transition toward sustainable practices.

Celtic Renewables' story is an inspiring narrative of innovation and commitment, showcasing how a forward-thinking approach can lead to groundbreaking achievements in the pursuit of cleaner and more sustainable energy solutions. Their flagship facility at Caledon Green stands as a symbol of progress, marking a significant step towards a greener and more environmentally conscious future.
