Transition to natural gas and biogas in Sweden
A long-term sustainable gas supply
Grontmij supports transition to natural gas and biogas in Stockholm’s town gas network.
By the summer of 2009, some 90,000 properties connected to Stockholm’s town gas network are to be ready for the transition from gas based on naphtha/light petroleum to natural gas and bio-gas. Grontmij has been commissioned by Stockholm Gas to manage the replacement of gas cookers and other gas appliances in connection with the changeover.
Grontmij has previously worked with Alyata in producing and analysing decision data for of the transition, which partly entailed making an inventory of all connected properties. The inventory ensures that as few gas customers as possible will be affected. Most cookers and gas appliances made after 1972 won’t have problems with the changeover. Grontmij has now been further entrusted to manage the conversion of the town gas net-work. Some 16,000 gas cookers and a couple of hundred other gas appliances will be replaced by more modern equipment.
“The gas conversion is a major environmentally enhancing adjustment in a short time span. The key is therefore to organise the work efficiently for everyone involved in the project. This is exactly the strength and expertise our experienced project managers can offer,” says Ulf Palmblad, Managing Director of Grontmij in Sweden.
Sustainability
The transition will not only improve the environment thanks to lower emissions and a long-term sustainable gas supply from renewable energy sources, it is also a more economically favourable option than oil-based gas, which is affected by rising oil prices and environmental taxes, for example.
