Gas emissions
Before it is burned, natural gas contains 80% methane, which is a strong greenhouse gas. In 2006 Continuon Netbeheer therefore continued to work on improving gas leakage detection and the reduction of leakages.
Due to grid leakage, the distribution of gas in the Netherlands leads to gas loss. In 2006 work was carried out to improve the inspections of grids and connections for gas leakages. In Amsterdam an initial test was performed with laser-assisted leakage inspections in collaboration with the supplier of the equipment. In 2007 extensive field tests will be carried out to see whether the laser technology is workable in daily practice. This will be done in cooperation with NetCare of the Network Services Division.In 2005 a new gas connection for use in subsiding soil was developed in conjunction with other grid managers. Unlike plastic pipes, traditional cast-iron pipes can be damaged when soil subsidence takes place, which results in gas leakages. Against expectations the new connection was not yet introduced in 2006. The actual connection has been fully developed and certified, but constructionally it does not fit the facilities made available by contractors in new-build projects. As a result, they could not be applied. Early in 2007 consultation will take place between representatives of construction firms and grid managers in order to solve the problem. In addition, we also expect to pilot the redesigned connection as a replacement for connecting pipes in existing houses in 2007.
