The article discusses the importance of carbon fibre (CF) in achieving net zero targets in transportation and renewable energy, highlighting its critical role in lightweighting vehicles and enabling wind power generation and hydrogen energy storage solutions. Despite its significance, CF production processes have high embodied carbon, necessitating a focus on decarbonisation strategies. The study utilizes lifecycle assessment to evaluate the impact of future energy scenarios and alternative feedstock materials on CF production. Achieving net zero electricity generation could result in a 50% reduction in CF Global Warming Potential (GWP). Transitioning to alternative thermal energy sources like BioMethane and eMethane shows promise, with eMethane projected to achieve a 99% reduction in GWP by 2050. Producers are advised to consider BioMethane as a short-term solution before shifting to eMethane as a long-term thermal energy source. Furthermore, the article recommends prioritizing the use of bio-based acrylonitrile feedstock to further reduce CF's GWP. Overall, the research underlines the potential of decarbonization strategies in CF production towards sustainable future energy solutions.
