The University of Lincoln’s “Reverse Coal” project, specifically the Climate-neutral Integrated Systems for Agriculture, Farming, Energy and the Environment (Climate SAFE) initiative, has been recognized with the 2025 UK and Ireland Green Gown Award for Research with Impact. This prestigious national sustainability accolade celebrates the world-leading research collaboration between the university’s Lincoln Institute for Agri-Food Technology and industry partner Pollybell Farm, part of the Lapwing Estate in South Yorkshire, United Kingdom. The project has been affirmed as a national leader in research that delivers significant real-world environmental and economic benefits by integrating innovation across agriculture, energy, and land use.

The fundamental challenge addressed by the Climate SAFE project is the reliance on conventional systems that release carbon into the atmosphere. The team aimed to create a complete reversal of the traditional approach to fossil fuel energy and agricultural emissions. The goal was to establish a functional, commercially viable system that utilizes nature and technology in concert to actively remove carbon dioxide from the atmosphere, proving that farming, energy generation, and food production could operate hand in hand for a sustainable, climate-neutral future.

The solution is a closed-loop, integrated system built on sustainable biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More sourcing and thermochemical conversion. The process begins with planting fast-growing willow trees, which serve as the feedstockFeedstock refers to the raw organic material used to produce biochar. This can include a wide range of materials, such as wood chips, agricultural residues, and animal manure. More by absorbing atmospheric carbon dioxide. Once harvested, this biomass is subjected to pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More, a process that involves heating the plant material to high temperatures in an oxygen-deprived environment. This transforms the willow into biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More, effectively locking the absorbed carbon safely away. Critically, the heat produced during the pyrolytic conversion is captured and utilized to power high-tech glasshouses, enabling year-round, fresh food production.

The demonstrable success of this model earned the Green Gown Award and provided measurable environmental results. For every square meter of the Climate SAFE system in operation, approximately 216 grams of carbon dioxide are removed from the atmosphere. Funded by the UK’s Department for Energy Security and Net Zero, the project is hosted at Pollybell Farm and offers a practical, replicable blueprint for farms not only across the UK but internationally. It confirms that the combination of carbon removal and renewable energy can underpin agricultural resilience.

The primary lesson learned from the Climate SAFE initiative is the imperative of interdisciplinary and inter-organizational collaboration. The success was built upon the partnership between academic expertise (engineering, environmental science, agri-tech) and real-world farming practices (The Lapwing Estate). For the biochar industry, this model underscores the value of integrated, decentralized systems: biochar production should not be viewed in isolation but as a foundational component within a larger, high-value ecosystem that simultaneously generates renewable heat, captures carbon, and supports resilient food production.
