Passengers make Ireland’s first biogas bus journey

Bus travellers in Cork were recently the first passengers in Ireland to ride a zero carbon emissions, biomethane-powered bus.

The bus is a viable alternative for Ireland’s public bus fleet, and the biogas bus has been part of national trials looking at green bus performance, air quality impacts and CO2 emissions, among other criteria.

Biomethane is a clean, renewable gas that is 98 per cent methane. Also known as green gas, it can be used interchangeably with conventional fossil-fuel natural gas, meaning it can be added to the existing gas grid. The majority of European capital cities now run their buses on gas, resulting in lower carbon emissions and better air quality in cities.

Michelle O’Sullivan, Energy Cork spokesperson and Cork Chamber Public Affairs Senior Executive said: “Never has the demand for public transport been greater in Cork with the city centre expecting an additional 10,000 jobs in the next five years. We have the opportunity now to shape how we grow and be proactive in adopting technologies that work for the City and which protect our environment and air quality.

“This technology is tried and tested with examples of biomethane bus fleets in Stockholm, Lille and Nottingham to name just a few cities. We are very keen to see this technology supported by the National Transport Authority and hope to see these buses rolled out in Cork in the not too distant future.”

Faced with EU deadlines to reduce harmful greenhouse gases, and following Budget 2018, Ireland will no longer be able to purchase diesel buses for public transport as of July 1, 2019. The Department of Transport, Tourism & Sport has been carrying out technology trials of hybrid diesel, fully electric, electric hybrid, compressed natural gas (CNG) and biomethane powered buses in Cork and Dublin in recent months to review performance.

Energy Cork, which brings together Cork City Council, Cork County Council, Gas Networks Ireland, Bus Eireann, Cork Chamber and other regional stakeholders, has been working closely to garner support for green bus routes throughout the city and county. Following the success of Drive4Zero, which incentivised Cork commuters to switch to electric cars, Energy Cork believes that green buses are vital to the sustainable infrastructure and development of Cork in the future.
