SUSTAINABILITY
RESEARCH
Partner with U of T Engineering

Over the last century, technology has enabled standard-of-living improvements around the world. At the same time, thriving cities and growing populations take a toll: lakes, rivers and oceans have become polluted, air quality in major cities is poor and our climate is changing.

U of T Engineering researchers are at the forefront of sustainable alternative technologies that can mitigate these impacts. We are creating new ways to harvest energy from the sun and wind, and efficiently store it. We are developing cleaner, more efficient engines that can run on biofuels without compromising safety or reliability. And we are designing better ways to move people through cities in order to make our urban environments more livable.

Together with industrial partners in diverse sectors, our leading-edge research is helping companies make better use of resources and enabling access to new technologies for a cleaner, greener and more sustainable future.

RESEARCH IMPACT

Cleaner Energy Through Hydrogen

 

Solar and wind installations provide clean power, but storing that energy for days when conditions are cloudy with no wind is still a major challenge. One solution is to use electrolyzers, which take renewable electricity and use it to split water into hydrogen and oxygen gas. The hydrogen can later be used in a fuel cell that reverses the process, recombining H2 and O2 to produce electricity and water.

Mechanical engineering professor and director of the Institute for Sustainable Energy AIMY BAZYLAK (middle) holds the Canada Research Chair in Thermofluidics for Clean Energy, and leads a team of experts specializing in polymer electrolyte membrane (PEM) fuel cells and electrolyzers. By designing new materials and formulations for electrochemical energy conversion, Bazylak and her team are improving the efficiency and reliability of fuel cells and electrolyzers while keeping costs low. Better electrolyzers and fuel cells could enable efficient, long-term storage of renewable power.

Smart Cities are Sustainable Cities

 

Over half the world’s population now lives in cities. By centralizing resources, urbanization has the potential to greatly reduce per capita environmental impact. But it can also lead to gridlock, air pollution and other challenges that threaten our health.

Professor ERIC MILLER is the director of the University of Toronto Transportation Research Institute (UTTRI) in the Department of Civil & Mineral Engineering, which helps cities grow in a more sustainable way. UTTRI brings together more than two dozen experts from engineering, economics, policy, urban geography and computer science. Through data gathering, analysis and modelling, UTTRI researchers provide system-wide, evidence-based policy analysis and decision support.

Ongoing projects include analysis of the effectiveness of new bike lanes installed on Toronto’s Bloor Street and using artificial intelligence and machine learning to optimize the timing of traffic lights through an intersection. By working with urban governments, city planners and companies in the transportation sector including Miovision, IBM Canada and Esri Canada, UTTRI is ushering in a new era of smarter, greener cities.

Emma Master

From Plants to Plastics

In Canada, the forest is our largest bio-based feedstock. Yet despite the increasing demand for greener materials and the abundance of this renewable resource, many of the products we use on a daily basis are still made from non-renewable fossil fuels. Even for paper products, only a tiny fraction of the raw wood material makes it into the final product.

Designing reproducible and cost-effective processes for transforming wood into marketable products is technically challenging. Hemicellulose and lignin — which together make up more than half of the wood in a tree — are usually wasted, burned for power generation or discarded. Chemical engineering professor EMMA MASTER is leading a national Genome Canada initiative called SYNBIOMICS aimed at developing processes to create value-added products from this underutilized forest biomass.

Master and her colleagues are designing biocatalysts to upgrade rather than degrade cellulose, hemicellulose and lignin. Upgrading bypasses the challenges involved in breaking down these structures and builds on the unique qualities of each polymer for targeted applications. These applications include resins, coatings, bioplastics and adhesives for lightweight biocomposites. Working with several industry partners across the value-chain such as Canfor and Dupont, SYNBIOMICS aims to meet the precise specifications and consistency the market requires while reducing reliance on fossil fuels and revitalizing Canada’s forestry sector.

Ted Sargent

Spray-on Solar Power

 

Today, virtually all commercial solar cells are made from thin slices of crystalline silicon which must be processed to a very high purity. It’s an energy-intensive process, requiring temperatures higher than 1,000 degrees Celsius and large volumes of hazardous solvents.

However, silicon isn’t the only path to solar power. Electrical and computer engineering professor TED SARGENT, Canada Research Chair in Nanotechnology, and his team are working on alternative technologies, from perovskite crystals to nanoparticles known as quantum dots. Both of these technologies enable the active ingredient to be mixed into a liquid, creating a kind of “solar ink.” Eventually, this material could be sprayed onto surfaces such as urban rooftops or used in traditional inkjet printing equipment to create solar cells at a fraction of current costs.

The team has also demonstrated the ability to combine a layer of quantum dots with a traditional silicon photovoltaic cell, creating a tandem device that harvests more of the solar spectrum than silicon alone. Sargent and his collaborators founded a spinoff company, QD Solar, to commercialize this technology. Their customers include leading solar manufacturers who want to give their products a boost at minimal cost.

THE FUTURE OF SUSTAINABILITY

Farming Algae for Food and Fuel

 

Algae are among the fastest-growing photosynthetic organisms on the planet. Like plants, they absorb climate-warming CO2 as well as nitrogen and phosphorus, which are often present in wastewater. Some species can accumulate fats and oils that could be turned into biofuels and biochemicals; others produce nutritious molecules that make them useful for fish feed, animal feed or even human health supplements.

Professors GRANT ALLEN in Chemical Engineering and STEWART AITCHISON in Electrical and Computer Engineering are working together to see if algae grown on an industrial scale could clean wastewater, reduce air emissions and produce value-added products simultaneously. They have developed an efficient tool to pipe light into algae biofilms, and are collaborating with partners such as the National Research Council, Pond Biofuels, Biox Corp and Mara Renewables to develop new applications for algae in sectors such as carbon capture, nutraceuticals and biofuels.

Blue Skies Ahead

 

Every day, commercial flights burn over 100,000 litres of fuel, leading to significant harmful carbon dioxide emissions. Aerospace engineering professor DAVID ZINGG is the U of T Distinguished Professor of Computational Aerodynamics and Sustainable Aviation, and the founding director of the Centre for Research in Sustainable Aviation. In partnership with major aircraft manufacturers such as Bombardier and Airbus, Zingg and his colleagues are investigating novel aircraft configurations, stronger and lighter materials, and friction-reducing actuators to substantially improve aircraft fuel efficiency.

Clean Combustion

 

Whether it’s gasoline, diesel or jet fuel, combustion powers our society. Yet it also contributes to climate change and generates other emissions that impact local air quality.

Mechanical engineering professor MURRAY THOMSON is the director of the NSERC Collaborative Research and Training Experience (CREATE) program in Clean Combustion Engines, a national network that includes industry partners such as Ford, Rolls-Royce and Pratt & Whitney. Together, Thomson and his collaborators are training a new generation of combustion experts who will redesign engines to lower emissions, improve fuel efficiency and enable the adoption of biofuels. The program includes an intensive Combustion Summer School as well as opportunities for students to take on internships with partner companies.
