Increased use of biogas in Stockholm

Yesterday, Stockholm city arranged a lunch seminar on future transports with Environmental Chancellor of Stockholm, Ulla Hamilton: http://ullahamilton.se/

I was invited to present opportunities for future buses and presented a new quantification of the impact of: changing mode of transport, improving the bus, improving the infrastructure to give buses priority in traffic and to change to biofuels. As it turns out, there is a high potential in all four measures.

Stockholm city is certainly a good example to mention when it comes to bio fuels. The use of biogas will increase and the commitments are secured by long term contracts.

The pros and cons of the Stockholm ethanol bus fleet were discussed, following the recent debate on food or fuel. The concern for the increasing price of food and bio fuel, urge for more distinct actions to realise the 2nd generation of bio fuel. Still, the impact of land use needs to be further monitored. The issue is complex and long term political commitments are needed for bus manufacturers and operators. However, Stockholm is also in the frontline of the biogas development. Solid commitments are secured by long term contracts and investments in production plants that produce biogas from sewage and other biomass wastes.

The local airport authorities presented a plan to decrease the environmental impact of the flights and air port operation. Arlanda airport is obliged to keep the CO2 emissions below the level of 1990. This presents quite a challenge now considering the increase in number of flights. The airport is considered as a hub including all land transports and transports by travellers to and from the airport. Interestingly, and as noted previously in this blog, biodiesel fuelled buses is a part of the solution.
