Upskilling Plumber Gasfitters for Hydrogen: An Empirical Study using the Theory of Planned Behavior

Hydrogen has become an important component of the global transition to zero-carbon economies. Low-carbon and green hydrogen gas and fuel cell technology for domestic household use will depend on skilled practi tioners, particularly gasfitters, to convert, install, and maintain hydrogen-based appliances. Upskilling gasfitters to work with hydrogen is critical to transitioning from natural gas to hydrogen for heating and cooking. Yet, limited research exists on training and upskilling trade practitioners in the context of renewable energy and lowcarbon technologies. This paper makes a novel contribution to research on upskilling for renewable and lowcarbon technologies by drawing on the findings from a survey of 1001 plumbers in Australia. The survey, designed using the Theory of Planned Behavior, aimed to predict behaviors regarding hydrogen training and ascertain social and structural enablers for such behavior. The results show that plumbers have limited awareness of hydrogen, yet have positive attitudes towards upskilling to work with the low-carbon fuel. Perceived benefits to business sustainability, customer service and safety underpin the positive attitudes. The research shows that while plumbers are enthusiastic about upskilling for hydrogen, upskilling policies and programs must ensure key stakeholders who inform plumbers’ ongoing practice are on board and informed about hydrogen training opportunities.
