In the heart of Sheffield, researchers are cooking up a storm, not in a kitchen, but in a lab. They’re brewing up a sustainable future for the chemical industry, and it’s all thanks to a humble molecule: formic acid. Gabriela A. Cuevas-Castillo, a researcher from the University of Sheffield’s Department of Mechanical Engineering, is leading the charge, exploring a novel process that could revolutionize the way we produce this versatile chemical.
Formic acid, a simple compound with a pungent odor, is a jack-of-all-trades in the chemical industry. It’s used in agriculture to control pests, in food preservation to extend shelf life, and even as a potential hydrogen storage medium. But traditional production methods are far from green, contributing significantly to global carbon emissions. Enter Cuevas-Castillo and her team, who are investigating a process called Power-to-Formic Acid (PtFA), which uses green hydrogen and carbon dioxide captured directly from the air.
The team’s findings, published in Cleaner Engineering and Technology, which translates to Cleaner Engineering and Technology, paint a promising picture. “The PtFA process shows a remarkable reduction in environmental impact,” Cuevas-Castillo explains. “We’re talking about a 92% reduction in CO2 equivalent emissions compared to conventional methods.”
But the benefits don’t stop at environmental impact. The study also conducted a techno-economic analysis, assessing the commercial viability of the PtFA process. While the minimum selling price of PtFA is currently higher than conventional formic acid, the team identified key areas for cost reduction, primarily in direct air capture (DAC) and electrolyser technologies.
So, what does this mean for the energy sector? Well, it’s a step towards defossilising the chemical industry, a significant contributor to global carbon emissions. By capturing carbon dioxide directly from the air and using green hydrogen, the PtFA process offers a sustainable alternative to traditional methods. And with the potential for cost reduction, it’s not just an environmental win, but a commercial one too.
The study is the first of its kind to holistically assess a PtFA process from technical, economic, and environmental perspectives. It’s a significant step forward in the quest for a sustainable chemical industry, and it’s happening right here in Sheffield. As Cuevas-Castillo puts it, “This study provides new and important information regarding a sustainable chemical industry. It’s a step towards a greener future, and we’re excited to be at the forefront of it.”
The research opens up avenues for future developments. As technologies like DAC and electrolyzers advance, the economic viability of PtFA could improve significantly. Moreover, the study’s findings could influence policy decisions, encouraging investments in green technologies and sustainable chemical production methods. It’s a testament to the power of innovation and the potential of sustainable technologies to shape our future.
