Since October, TÜV Rheinland, German vitality provider GVG Rhein-Erft, and community operator Rheinische Netzgesellschaft (RNG) have examined the impact of including 20% hydrogen to the gasoline community in Erftstadt, close to Cologne, Germany. .
On the finish of the heating interval, the companions made an interim stability and located that every one linked gasoline consumption gadgets had been operating with out errors. Previous to this experiment, German regulation allowed hydrogen to be blended as much as 10%.
In keeping with TÜV Rheinland, residence and enterprise house owners had been in a position to make use of their gadgets as traditional through the heating season. It doesn’t have to be modified for the modified composition of the gasoline combination, which additionally has no impact on the common operation of the gasoline community.
The sphere take a look at is scheduled to final till the top of December. A complete of 100 households from the districts of Niederberg, Borr, and Friesheim participated. The districts are significantly appropriate for a discipline take a look at of this sort, because the community, which is nearly 9 km lengthy, was inbuilt 2007.
TÜV Rheinland performed the primary discipline take a look at in Germany on an L-gas community, which differs from the H-gas community by way of gasoline composition and origin. L-gas, which is equipped in western Germany, has a decrease vitality content material (80-87% methane) and is cheaper in comparison with H-gas, which has 87-99% methane and a better vitality content material. and value.
TÜV Rheinland, GVG Rhein-Erft, and RNG are working collectively to introduce hydrogen to the take a look at web site in a number of levels. At first, they blended 10% hydrogen with pure gasoline, and after 4 weeks, they steadily elevated the proportion to fifteen%. As of October 2022, the gasoline community operates with a 20% hydrogen admixture.
“Within the run-up, we uncovered all gas-consuming gadgets within the take a look at space to check gasoline with 23% hydrogen. This enabled us to make sure the suitability of every particular person gasoline equipment within the challenge space,” defined the challenge supervisor. Mr. Michael Thys (GVG).
TÜV Rheinland plans to develop its testing to evaluate the technical potentialities of a hydrogen admixture of as much as 30% in appropriate gasoline networks.
