Green hydrogen as heat source for houses
Research by grid manager Stedin and research institute Kiwa shows that all 600 homes in Stad aan ‘t Haringvliet can be heated with green hydrogen. Stedin’s existing gas network can be used for this. The study shows that the village’s gas network can be switched to hydrogen with little cost and inconvenience to residents.
A few adjustments
Network manager Stedin must make a few adjustments to the existing gas network to make it ready for the switch to hydrogen. For example, the fifteen-kilometre-long gas network in Stad aan ‘t Haringvliet must be flushed with nitrogen in order to remove natural gas from it. In addition, the four gas district stations must be modified and some households must replace the gas meter in the meter box.
Checking gas pipes
In the houses, the gas pipes have to be checked and the traditional natural gas central heating boiler has to be replaced by a hydrogen boiler. These adjustments take half a day. The whole village can be switched to hydrogen in a few weeks.
Stad aan ‘t Haringvliet is located on the island of Goeree-Overflakkee and is surrounded by wind and solar farms. This makes the location very suitable for the production of green hydrogen. The old detached houses in the village are difficult to insulate and are therefore less suitable for low-temperature heating. Heat pumps are therefore a poor alternative.
