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 fuel community in Erftstadt, close to Cologne, Germany. .
On the finish of the heating interval, the companions made an interim steadiness and located that each one linked fuel consumption units have been working with out errors. Previous to this experiment, German legislation allowed hydrogen to be combined as much as 10%.
In keeping with TÜV Rheinland, house and enterprise homeowners have been in a position to make use of their units as common through the heating season. It doesn’t have to be modified for the modified composition of the fuel combination, which additionally has no impact on the common operation of the fuel 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 subject take a look at of this sort, for the reason that community, which is nearly 9 km lengthy, was in-built 2007.
TÜV Rheinland performed the primary subject take a look at in Germany on an L-gas community, which differs from the H-gas community by way of fuel composition and origin. L-gas, which is provided 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 price.
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 phases. At first, they combined 10% hydrogen with pure fuel, and after 4 weeks, they regularly elevated the proportion to fifteen%. As of October 2022, the fuel community operates with a 20% hydrogen admixture.
“Within the run-up, we uncovered all gas-consuming units within the take a look at space to check fuel with 23% hydrogen. This enabled us to make sure the suitability of every particular person fuel system within the mission space,” the supervisor defined. of the mission 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 fuel networks.
