The first “power-to-gas” plant inaugurated in Dietikon (ZH) makes it possible to make a contribution to climate neutrality and to become less dependent on foreign gases.

The first power-to-gas plant was inaugurated in Switzerland on Friday. Installed at Limeco, a plant in the Limmat Valley in Dietikon (ZH), it will contribute to supplying Switzerland with renewable gas.

“With an electrolysis capacity of 2.5 megawatts (MW), it produces around 18,000 megawatt hours (MWh) of synthetic renewable gas per year. The plant thus makes an important contribution to the decarbonization of the country, as it makes it possible to save up to 5,000 tons of CO₂ per year year,” explains Limeco in a press release.

Today it is no longer just about achieving climate goals, the “Switzerland at the weekend” specifies. Since the beginning of the war in Ukraine, it has become important to reduce Switzerland’s dependence on gas imports. The German-language newspaper recalls that Switzerland imports almost all of its annual gas requirements (around 32 terawatt hours) from abroad and almost half from Russia.

On the occasion of the inauguration of “Power-to-Gas”, Ronny Kaufmann, head of Swisspower – the strategic alliance of 22 Swiss industrial services and regional energy, sewage, waste disposal and media service providers, emphasized the “enormous potential” of the plant. He puts the potential production of Swiss synthesis gas at five to ten TWh per year. So, of course, a single installation will not be enough, but “with this technology, Switzerland could replace almost half of all Russian gas imports,” he continues. He now hopes for the support of the federal government, “because we now have to build a lot and quickly,” he concludes.

The Swiss Federal Office of Energy (SFOE) supported the Limeco project with CHF 1.7 million through its innovation pool. Its director Benoît Revaz specified in the “Switzerland at the weekend” that the OVEN would not play a more important role. Companies and their owners are now in demand.

The “Power-to-Gas” plant shows that national production of renewable gas is possible “and everything that can be produced here does not have to be imported because it is crucial that Switzerland becomes less dependent on foreign natural gas”. , he sums up .
