The world's first asphalt plant on hydrogen
At Veidekke's asphalt factory in Kristiansund, 3,000 tonnes of asphalt were produced using hydrogen as the sole energy source.
This is the first time in history that asphalt is produced without greenhouse gas emissions, and the plant has been developed in close cooperation with the German industrial group Benninghoven and supported by Enova.
"The asphalt contractors, customers and authorities in Norway have all set tough climate targets. But it is impossible to achieve the necessary reductions with the current focus primarily on electric vehicles and machinery. These account for less than 20% of the total emissions from raw materials, production and laying of asphalt in Norway. The use of hydrogen in the plants alone can reduce overall emissions by 40%, and the environment doesn’t distinguish between direct and indirect emissions," says Martin Holmqvist, director of Veidekke Asphalt.
"Germany and large EU countries recognise that hydrogen is the most realistic emission-free energy option for, among other things, asphalt production. And hydrogen can be produced by wind turbines even when it is windy, from solar parks in summer and hydropower during precipitation peaks. That is why there is so much interest from other countries in our production of asphalt with hydrogen in Kristiansund this autumn," says Øivind Larsen, EVP of Veidekke Infrastructure.
"We are rapidly approaching 2030, and it will take great courage and innovative thinking to reduce greenhouse gas emissions enough to make a properly difference. We are completely dependent on clear guidelines and priorities, both politically and from our customers, in order to meet our shared climate commitments. We have now proven that it is possible to produce with hydrogen alone, and can use large volumes at our 25 asphalt plants if there is full-scale industrial production and distribution of hydrogen in Norway,” Larsen concludes.
The production of asphalt is a significant source of emissions with approx. 400,000 tonnes of CO2 in Norway each year. An asphalt plant requires so much energy that electricity cannot be used in production, and the alternatives so far have been gas, propane, diesel, biodiesel and wood pellets, all of which have their own greenhouse gas emissions. In addition, the EU has adopted stricter requirements for the use of forests and has made clear that the use of wood and pellets for energy purposes will be limited (the Renewables Directive) from 2027.
