LEAG plans 950 MW power-to-gas plant at lignite mine – pv magazine International



Germany’s second largest power provider, LEAG, plans to provide hydrogen by means of a power-to-gas plant at its lignite open-cast mine in Higher Lusatia, Germany.

The corporate has filed an approval request with the Brandenburg State Workplace for the Atmosphere, and the undertaking, known as the Revolutionary Storage Energy Plant, is at present present process a public session course of. Immission management is a serious concern for the businesses concerned.

LEAG’s power-to-X facility will retailer electrical energy from wind and solar energy in two parallel techniques. It should use a 40 MW electrolyzer to provide 700 kg of hydrogen per hour. The corporate goals to show hydrogen into electrical energy by means of a gasoline and steam turbine mixed cycle energy plant with a capability of 945 MW.

The storage energy plant may also embrace a thermal solid-state storage facility with a capability of 1,000 MWh, built-in with a gasoline turbine system to optimize power yield. Afry, a German engineering firm, is chargeable for designing the undertaking. Within the preliminary growth part, the H2-ready turbine will convert 53% hydrogen into electrical energy in a pure gasoline combination. LEAG plans to change the turbine to run on pure hydrogen at a later stage.

Based on Afry engineers, the system was designed to rely solely on thermal storage from day one, enabling a very CO₂-free energy provide. Moreover producing electrical energy by burning in a gasoline turbine, hydrogen can be transformed into electrical energy in gasoline cells. The system shops hydrogen at 400 bar, and native public transport buses can refuel immediately on the facility.

The Lusatia lignite opencast mine has been reworked into an intensive power park for wind energy, photovoltaics, battery storage, and power-to-X. The objective is to have 7 GW of producing capability by 2030, with photovoltaic output alone reaching 7 GW by 2040.

LEAG additionally plans to fee a 500 MWh storage facility utilizing iron redox flux storage know-how from US producer ESS on the Boxberg energy plant in Lusatia.
