A low carbon long term replacement strategy for Uniper’s existing unabated asset at Connah’s Quay by developing a new combined-cycle gas turbine (CCGT) fitted with carbon capture technology to capture CO2 emissions.

550 MW capacity ​ (with later expansion to ~1.1GW)​ ~1.2 Mt CO2 ​ captured per year​

​

Shaping a green hydrogen economy in the Central German Chemical Triangle with stand-alone supply of renewable energy to an electrolyzer to produce green hydrogen. 

3,000 tons ​approx. (~99 GWh) per annum of green hydrogen in the first stage​

Development of an industrial electrolyser at Uniper’s powerplant site in Wilhelmshaven. Project starts with an initial 200 MW electrolyser, which will be scaled up to a gigawatt-size facility in line with growing demand.

200 MWel ​electrolytic H2 production capacity in Phase 1 (20 ktpa H2 output) with expansion capacity of up to 1GWel​

Import terminal for green and blue hydrogen (from ammonia cracking) at Uniper’s terminal site. Germany’s only deep-water port for large-scale import vessels, and unique connection to Germany's largest salt caverns for hydrogen storage position.

300 ktpa​ from ammonia import & conversion

​

Setting up a hydrogen hub in Huntorf, Lower Saxony to generate hydrogen using renewable energy, store it there and create transport facilities to make it available to industry and the mobility sector. The site also offers the possibility of using hydrogen in highly efficient Compressed Air Energy Storage.

30 MWel​ electrolysis capacity for green hydrogen (Upscalling up to 300 MWel)​

The execution of the revitalization of the largest pumped storage hydropower plant in Bavaria/South Germany after 47 years of operation (commissioning ‘64), ​ it was shut down in 2011, after recurring bed collapses in the upper reservoir.Happurg will add a large-scale, flexible 160 MW storage element to Uniper’s clean dispatchable power portfolio.

160 MW ​209 m drop; upper basin volume of 1.8mio. m³; storing water with an energy content of 840 MWh of electricity​

The aim is to transform the power plant site into a modern energy and technology centre. The basis for this is the termination of power generation from coal and the new combined heat and power (CHP) plant. However, switching from coal to gas is only the first step on the site's path to transformation. Further possible options include the conversion of the new CHP plant to H2-ready and new H2-ready power plants at the site. H2-ready means that these power plants can also be operated with hydrogen in the future (project developments are underway).   

NorthStarH2 aims to develop, build and operate a “Power-to-Methanol” (eMethanol) plant at the Lugnvik industrial site in Östersund, Sweden to convert up to 140 kt biogenic CO2 combined with ca.1.1 TWh renewable electricity annually to produce up to 112 kt eMethanol.
