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.

与人类对健康长寿的渴望类似，我们能源供应的长寿是我们社会可持续性的关键因素。在这方面，寿命指的是能源系统在排放和资源使用方面的可持续性，以及系统内使用的设备的寿命。能源系统的“从摇篮到坟墓”的生命周期评估捕捉到了这两个特征。无论选择哪种技术，为了将能源系统对环境的影响降到最低，用于能量存储和转换的设备的长寿命是绝对必要的。 预计电化学能源系统将在从以化石燃料为基础的能源系统向以可再生和替代能源为基础的可持续“绿色”社会的过渡中发挥关键作用。电池和燃料电池等电化学储能和转换系统提供了两个非常有利的系统级特征：1)能效的变革性水平；2)使用点的零排放。与现有技术相比，这些特征转化为全球温室气体排放的减少和我们社区空气质量的改善。然而，与任何新兴技术一样，寿命挑战可能会对社区的广泛接受构成风险。 因此，拟议研究计划的总体目标是提高用于电化学能量存储和转换的设备的寿命，重点是燃料电池、氧化还原液流电池和电解槽。这种进步不仅将对能源系统的可持续性产生积极影响，而且还将大大降低总拥有成本，加快商业化和市场部署的速度。该研究计划的长期愿景是转让新知识和技术，并与加拿大日益增长的清洁技术行业合作，开发市场上最耐用、最可靠的电化学能量转换和存储系统，并将其商业化。更重要的是，这项研究将培养下一代工程师，他们将为该行业提供未来的劳动力。总体而言，电化学能源系统市场渗透率的提高将大大减少加拿大及其他地区城市地区的温室气体排放和污染。
