Queen’s researcher Rachel Baker (Chemical Engineering) has been awarded the prestigious Polanyi Prize in Chemistry for pioneering greener approaches in chemical manufacturing. Modeled after the five Nobel Prize categories, the Polanyi Prize recognizes outstanding early-career researchers whose innovations drive progress in fields vital to Ontario’s economic growth.

“Now more than ever, it is imperative that we drive innovation to build a stronger and more resilient Ontario,” said Nolan Quinn, Minister of Colleges, Universities, Research Excellence, and Security. “Our government is proud to honour and support our five Polanyi Prize winners for their groundbreaking research that plays a vital role in protecting our people, our economy, and our province.”

Dr. Baker’s vision is to reduce the chemical industry’s reliance on fossil fuels with a two-pronged approach using electrolysis reactions to repurpose biomass and carbon dioxide (CO₂) emissions. This cuts down on greenhouse gas production by utilizing clean electricity to power chemical reactions, while simultaneously using pollutants like CO₂ as a feedstock. 

Biomass is a renewable byproduct generated during the manufacturing of important chemicals such as biodiesel. By developing electrolysis reactions, the Baker Lab is exploring the conversion of these byproducts into sustainable chemicals, such as alcohols, hydrocarbons, and carboxylic acids, which are widely used in chemical, agrochemical, and pharmaceutical manufacturing. 

Similarly, these electrolysis reactions are also being developed to capture CO₂ from the atmosphere and convert it into chemical precursors essential for food and plastic production. These techniques could significantly lower the carbon footprint of chemical manufacturing, contributing to a more sustainable future.

“The chemical industry is a key driver of climate change, making it crucial to develop renewable practices while sustaining the production of valuable chemicals,” says Dr. Baker. “Being awarded the Polanyi Prize not only recognizes the extraordinary efforts of my team, but also the province’s commitment to improving sustainability in chemical manufacturing.”

This isn’t the first time Dr. Baker has received recognition for her exceptional early-career research. Previously, Dr. Baker was named to Forbes 30 Under 30 North America, an honour that highlights young leaders making a significant impact in their field. With the Polanyi Prize now added to her growing list of accolades, Dr. Baker continues to shape a more sustainable future through innovation and leadership in chemical engineering.
