Sean has spent his entire career applying technology to environmental challenges. He started his career as an environmental management consultant working for notable firms such as TRI – Technology Resource Inc. (acquired by Metro Testing + Engineering Ltd.) and Hemmera (acquired by Ausenco) assessing and remediating some of Canada’s worst contaminated sites.
In 2007, following completion of an MBA, Sean pivoted into cleantech commercialization after an MBA internship at leading clean energy VC, Chrysalix sparked his interest in the Energy Transition. Since then, Sean has helped to build two local technology success stories, 4Refuel and Corvus Energy.
Between 2007 and 2011, Sean held key roles on the 4Refuel management team, including VP Corporate Development and President and board member of its technology subsidiary. 4Refuel (now a Finning company) was a technology-enabled, fuel as-a-service business for commercial and industrial fleets – a decade or more ahead of similar business models Booster, Fill’d, Yoshi, etc. In 2011, Sean and other managers exited when the company was sold to private equity.
In 2011, Sean joined Corvus Energy when the company was pre-revenue and has helped to build the business into the market leader it is today with over 50% market share and an installed base on five continents. Corvus Energy supplies large-scale, lithium-ion batteries and fuel cells to the maritime industries, enabling hybrid and fully electric, zero emission ships, port equipment and offshore O&G and renewable energy installations.
Sean has seen all phases of start-up and scale-up from pre-revenue to $0.5B in revenue and has significant international experience. Sean volunteers as the Treasurer and steering committee member at the Vancouver Maritime Centre for Climate and enjoys living in the Vancouver areas with his wife and two children. Puchalski holds a B.Sc. (Microbiology, University of British Columbia), a B.Tech.
