Results of four-year European project to test technology presented at City Hall, highlighting need for more fuelling stations
Hydrogen fuel cell vehicles came under the spotlight in London this week (October 6), highlighting the need for refuelling infrastructure throughout the UK to support increased take-up of the zero-emission technology.
As it is a relatively new technology, take up of hydrogen powered vehicles has so far been slow and there are currently only four publically accessible hydrogen refuelling stations in the whole of the UK â€“ two in London, one in Swindon and another in Sheffield.
In 12 monthsâ€™ time it is hoped that this number will rise to 13 stations nationally â€“ including one in South Wales and two in Aberdeen, as well as a â€˜clustering approachâ€™ that will see a total of seven in London â€“ assisted through the government and industry-run H2 Mobility Project.
But, at City Hall on Tuesday, the Hydrogen Transport in European Cities (HyTEC) consortium â€“ which includes London among several other cities on the continent â€“ presented the results from its four year initiative to develop demonstration projects for hydrogen fuel cell vehicles, highlighting the need for more infrastructure to support vehicle take-up.
Speaking at the event, assistant director for environment at the Greater London Authority, Patrick Feehily, commented that it was â€œa good time to be talking about hydrogen vehicles given the Volkswagen scandalâ€.
He added that â€œhopefully it [the VW situation] will lead to positive outcome in terms of acceleration in the uptake of hydrogen vehiclesâ€, and called for support of innovation and collaborative working to bring down the costs of hydrogen infrastructure.
Hydrogen vehicles, Mr Feehily explained, offer â€œan important wayâ€ of dealing with air quality issues in the capital, where 63% of nitrogen oxide emissions come from transport while the population is set to surpass 11 million by 2050.
But while speakers at the event presented positive results and feedback from trials of the vehicles in London, Oslo and Copenhagen, the negative feedback they highlighted often related to the current lack of places to refuel the vehicles.
The London project saw two Hyundai 1×35 hydrogen fuel cell vehicles trialled by operational management teams as part of Transport for Londonâ€™s (TfL) 1,300-strong fleet, as well as the deployment of the UKâ€™s first standalone hydrogen fuelling station at Heathrow Airport in 2012
Presenting some of the findings, TfLâ€™s investigations officer Simon Scarfe explained that the Hyundai cars were used to check bus diversion routes and carry out meetings, reporting that there are â€œa lot of positivesâ€ with the technology and that the users â€œlike the vehiclesâ€.
However, he said that the â€œrange is maybe an issue when you donâ€™t have as many fuelling stationsâ€ and suggested that â€œthere needs to be an increase in the number of refuelling stations in Londonâ€.
The focus for future hydrogen infrastructure, Mr Scarfe said, would be South London, where there are more bus routes as 80% of the London Underground tube network is based north of the River Thames.
The current lack of refuelling stations was also highlighted by Dennis Hayter, group business development director at Intelligent Energy, although overall he too presented positive results from an additional London trial of five fuel cell hybrid taxis.
The hydrogen black cabs were funded by HyTEC and used during the London 2012 Olympics to transport visiting dignitaries as well as VIPs such as Rupert Murdoch, Barbara Windsor and Arnold Schwarzenegger.
Hydrogen taxis presented particular issues which needed exploring, he said, as they are â€œrelatively unique vehiclesâ€ and â€œneed to be able to operate at 20mph for long periods but equally need to drive at the limit of 70mphâ€ throughout the day.
Co-funded by transport companies and the European Commissionâ€™s Fuel Cell Hydrogen Joint Undertaking, HyTEC aims to explore how hydrogen vehicle infrastructure can be rolled out across Europe and produced a â€˜best practice guideâ€™ for cities seeking to adopt the technology, which was also available at City Hall this week.
Commenting on the event, Deputy Mayor for environment and energy, Matthew Pencharz, described the project findings as â€œa huge step forward for a newly developing industry that will have a massive impact on reducing carbon emissions and improving air quality through switching to a cleaner alternative for transport. HyTEC has now given us tangible results on how infrastructure needs to be developed in tandem with the promotion of hydrogen cars.â€
