Challenge / Goal
In order to replace fossil fuelled vehicles, both electric and sustainable biofuels are necessary. In Sweden the market for alternative fuelled cars is already developed. However, the market for the heavy vehicles, such as distribution trucks, is moving much more slowly.The City of Stockholm recognises that in order to get more heavy vehicles operating on biofuels, filling stations providing biofuels are needed. To push the market, barriers to the adoption of alternative-fuel heavy duty vehicles need to be removed and incentives introduced. A renewable fuelling station for heavy vehicles is an important step in this process.
The City of Stockholm is trying to find suitable locations for renewable feulling stations. Some of the stations will be completely new stations and some will be adding alternative fuels to existing diesel stations. The land is leased to filling station operators at a standard price, on the condition that at least two of the following alternative fuels are supplied at each station.
- Biogas: Methane gas from waste water treatment plants and food wastes in Stockholm. Cleaned and compressed biogas can be used in CNG vehicles.
- ED95: An ethanol fuel mix with 95 percent ethanol and 5 percent additive which makes the fuel ignite. ED95 is produced in Sweden from cereals and leftovers from the paper industry. Ethanol is also imported from other parts of the world. ED95 can be used in diesel engines which have been adapted for ED95.
- HVO: Hydrogenated vegetable oil, processed vegetable and animal oils with diesel quality. HVO can be used in diesel engines.
- RME: Rapeseed Methyl Ester, a form of biodiesel made from rape seeds
in Årsta, an extension of the gas grid is needed in order to connect the new filling station for heavy trucks with the existing gas grid. In this way biogas can be distributed to the station through the grid. This extension, along with a pre-study for the layout of the grid, will be done by Stockholm Gas AB, a company 51 percent owned by the City of Stockholm.
