Hydrogen Bus Trials by National Transport Authority (Ireland), 2021
About this good practice
Between 2020 and 2021, Ireland's National Transport Authority introduced a pioneering public transport initiative. They deployed three innovative double-decker buses powered by hydrogen fuel cells and electric motors on a route connecting Dublin to Ratoath in County Meath, operated by Bus Éireann.
By the close of 2021, these vehicles had collectively traveled more than 40,000km. Their operation consumed just over 2,300 kilograms of hydrogen, which was used to charge the primary electric drivetrain batteries. For comparison, traditional diesel buses would have used approximately 13,000 liters of fuel to cover the same distance on identical routes.
The new buses received positive feedback from both passengers and drivers. They appreciated the environmental advantages, reduced noise pollution, enhanced safety features, and overall performance of these innovative vehicles.
Resources needed
The total budget was c. €2.4 million at the time.
Evidence of success
This initiative resulted in a significant environmental benefit, with an estimated reduction of about 34,000 kilograms of CO2 emissions in less than half a year of operation. The trial phase demonstrated the technology's high reliability, with hydrogen consumption aligning closely with projected figures.
Potential for learning or transfer
The trial has very good potential but the cost would make it hard to replicate. Government support is fundamental for scaling and integration. The trial also highlighted the need for hydrogen production, something that isn't in place in Ireland at the moment. The operational benefits of fuel cell buses, such as longer driving ranges and shorter refueling times, make them a viable option for public transport systems. It should be then considered as a possible alternative if granted government funding.
