Hydrogen Buses in Jyväskylä: A Glimpse into the Future of Nordic Transportation
Jyväskylä, Finland, is currently at the forefront of a unique Nordic test, deploying five hydrogen buses in regular service. This initiative, supported by Toyota, aims to find a zero-emission solution for heavy vehicles – a sector lagging behind in the transition to sustainable transport.
The Challenge of Heavy Vehicle Emissions
While electric vehicles are gaining popularity for personal transport, electrifying heavy-duty vehicles like long-distance buses and trucks presents significant hurdles. Batteries add considerable weight, reducing cargo capacity, and require extremely fast charging infrastructure along routes. This is where hydrogen emerges as a potential alternative.
Currently, long-distance buses and trucks still largely rely on fossil diesel. The transition to cleaner alternatives is unhurried, prompting exploration of hydrogen as a viable solution.
Toyota’s Investment and the Cefmof Foundation
The Jyväskylä test is made possible by approximately ten million euros in funding from Toyota, which builds its rally cars in the Finnish rally capital. The world’s largest automaker established the Cefmof (Central Finland Mobility Foundation) alongside Toyota Mobility Foundation and the City of Jyväskylä to test green solutions locally.
Toyota Gazoo Racing World Rally team builds 50 rally cars annually in Jyväskylä, contributing to the region’s expertise in automotive technology.
How Hydrogen Buses Operate
The hydrogen buses being tested store gas under pressure in five tanks, totaling 37.5 kilograms. A fuel cell converts the hydrogen into electricity, powering the bus’s electric motor. A battery, approximately 75 kilowatt-hours, acts as a buffer, storing energy generated by the fuel cell.
All technology, except the motor, is located on the roof of the bus.
The Current Obstacles: Cost and Infrastructure
Despite the promise, challenges remain. A kilogram of hydrogen currently costs 12.64 euros at the pump. The lack of refueling stations is another significant barrier. Koiviston Auto, the operator of the bus service, receives support to offset the higher fuel costs and benefits from discounted bus rentals.
“Driving on hydrogen is not profitable without public support. But the foundation made this trial possible. If we can increase volumes, we believe hydrogen could grow profitable,” says Esa Eerola, program manager at Cefmof.
The Potential of Green Hydrogen
Finland often experiences surplus energy from wind power. This excess electricity could be used to produce green hydrogen, potentially making it a more competitive fuel source. Experts believe that a price of ten euros per kilogram would create hydrogen more comparable to gasoline and diesel.
“Wind and solar power will dominate the energy market in the long run. That energy can be stored as green hydrogen, and the gas could actually become one of the most important fuels of the future,” says Peter Lund, professor emeritus of technical physics at Aalto University.
Expert Perspectives and Future Outlook
Peter Lund cautions that widespread commercial use of hydrogen in transportation is still some way off, realistically expecting to see more significant adoption towards the conclude of the 2030s, or even later. Karoliina Honkala, a chemistry professor at the University of Jyväskylä, emphasizes the need for breakthroughs in hydrogen production and storage technologies.
“It would be great if we could find better solutions within five years. There’s a lot of work being done all over the world on this,” Honkala states.
Hydrogen fuel cell technology suffers from lower efficiency compared to battery-electric systems. Significant energy is lost during both hydrogen production and conversion back to electricity, with 60-70% becoming waste heat. Battery buses, in contrast, achieve around 90% efficiency.
Jyväskylä Residents Embrace the New Buses
Local residents appear to be receptive to the new hydrogen buses, indicating a positive public attitude towards sustainable transportation options.
