Enhanced longevity of electrochemical energy systems

Similar to the human desire of a long and healthy life, the longevity of our energy supply is a critical attribute for the sustainability of our society. Longevity, in this context, refers to both the sustainability of the energy system in terms of emissions and resource use as well as the lifetime of the devices that are used within the system. Both characteristics are captured by a "cradle-to-grave" lifecycle assessment of the energy system. Regardless of the choice of technology, a long lifetime of the devices used for energy storage and conversion is absolutely essential in order to minimize the impact of the energy system on the environment.***Electrochemical energy systems are anticipated to play a key role in the transition from a fossil fuel based energy system to a renewable and alternative energy based sustainable "green" society. Electrochemical energy storage and conversion systems such as batteries and fuel cells offer two highly favorable system level characteristics: 1) a transformative level of energy efficiency; and 2) zero emissions at the point of use. When compared to incumbent technologies, these characteristics translate into reduced greenhouse gas emissions on the global level and improved air quality in our communities. However, as with any new emerging technology, longevity challenges may pose a risk for widespread community acceptance.***The overall goal of the proposed research program is therefore to enhance the longevity of the devices used for electrochemical energy storage and conversion, focusing on fuel cells, redox flow batteries, and electrolyzers. Such advancements will not only have a positive impact on the sustainability of the energy system but will also greatly reduce the total cost of ownership and accelerate the rate of commercialization and market deployment. The long-term vision of this research program is to transfer the new knowledge and technologies and team up with the growing cleantech industry in Canada to develop and commercialize the most durable and reliable electrochemical energy conversion and storage systems on the market. More importantly, this research will train the next generation engineers who will provide the future workforce of this industry. Overall, increased market penetration of electrochemical energy systems will substantially reduce greenhouse gas emissions and pollution in urban areas in Canada and beyond.********
