CRH2: Hydrogen in Transit Fleets – How Does it Stack Up?
Résumé du webinaire
Transit buses face some of the toughest demands in transportation: long daily service hours, frequent stops and starts, heavy passenger loads, tight schedules, and, in Canada, extreme winter conditions. As transit agencies look for lower-emission options that can meet these demanding duty cycles, hydrogen-powered buses are emerging as a promising solution.
But how do they actually perform when the temperatures drop and the roads are packed with rush-hour riders?
Watch this webinar for an eye-opening look at one of Canada’s most comprehensive clean transit studies. As part of the Alberta Zero Emission Hydrogen Transit project, researchers compared hydrogen, battery-electric, and diesel buses operating in real-world service across Edmonton and Strathcona County, Drawing on more than 350,000 kilometres of operating data, this study examines what truly affects hydrogen use from day to day, from weather and road conditions to passenger loads and route demands.
In this webinar, you’ll discover:
- How Alberta’s harsh winters impact fuel consumption across vehicle platforms and what that means for transit planning.
- How route design—including hills, stop frequency, and speed—can make or break fuel efficiency.
- How hydrogen buses compare and complement battery electric and diesel in real-world conditions.
- Practical takeaways that transit agencies can use right now for fleet transitions.

Conseiller principal
Mark Lea-Wilson est ingénieur mécanicien et titulaire d’un MBA axé sur l’économie, la finance et la commercialisation des technologies. Il a 19 ans d’expérience dans l’industrie de l’énergie, où il a travaillé dans les domaines de l’innovation, du développement de produits, de la fabrication et de la gestion d’entreprise. Sa passion pour l’énergie et les systèmes énergétiques l’a amené à obtenir récemment un certificat de gestionnaire de l’énergie certifié (Certified Energy Manager). Il aime relier les informations entre les niveaux de système, et comprendre comment des détails peuvent affecter l’écosystème global, et inversement. Cela l’aide à formuler des stratégies et des systèmes d’entreprise efficaces.
L’expérience en ingénierie et en conception de produits qu’il a acquise au début de sa carrière l’a également aidé à comprendre les systèmes physiques aux niveaux macro et micro. Il accorde de l’importance à la curiosité, à la découverte, à la collaboration, à la science, au respect et à l’intégrité. Son dernier rôle en tant que directeur de l’innovation et actionnaire d’une entreprise manufacturière privée consistait à combiner les principes académiques et commerciaux les plus récents afin d’identifier et de mettre en œuvre des plans d’affaires innovants. Il s’agissait d’une combinaison de formation formelle, de travail de projet et de réseautage qui a abouti à de nouvelles lignes de produits, à des partenariats et à un projet de collaboration avec l’industrie visant à commercialiser les innovations. Cela l’a aidé à comprendre le chemin nuancé qu’il faut emprunter pour faire émerger de nouvelles idées. Auparavant, il était vice-président des opérations et supervisait les activités de fabrication, d’ingénierie, de chaîne d’approvisionnement et d’assemblage. Enracinée dans la production allégée et la réflexion sur les processus, cette fonction lui a appris qu’une équipe performante doit s’appuyer sur chacun de ses membres.
