J920 FleXtra, centerpiece of the largest cogeneration plant in North Germany

J920 FleXtra in Stapelfeld

Project 

HanseWerk Natur GmbH, in its endeavor to meet the ambitious German climate protection target, relies on the high-efficiency J920 FleXtra engine made by INNIO in Jenbach. This is the 53rd system by the engine specialists from Jenbach that has been configured for HanseWerk Natur. The 9.5 MW J920 FleXtra by INNIO is at the heart of North Germany’s largest cogeneration plant that works in conjunction with a waste to-energy plant as well as 19 additional heating plants, combined heat and power systems, multifunction storage and hybrid plants. The new facility, configured as a cogeneration plant (CHP) can supply up to 76 million kilowatt-hours of electric power annually, thus supplying around 21,500 households. In addition, up to 80 million kW of heat can be recovered for more than 6,000 average North German single-family houses. Heat storage units integrated into the plant ensure that the heat supply is maintained at peak load times as well as when the engine is forced to switch off due to high feed-in of renewable energy. 

Efficiency

HanseWerk Natur GmbH, a 100 percent subsidiary of HanseWerk AG, is a leading provider of distributed energy solutions in Northern Germany, offering customized energy solutions and power plant technology for optimized energy use. The company’s more than 20 years of expertise in operating CHP systems were also applied to the project in Stapelfeld. By combining a cogeneration plant with an NH³ heat pump, even a portion of the waste heat produced by the J920 FleXtra can be optimally employed as thermal energy and fed into the heating circuit. In total, the heat pump can increase the annual heat output of the power plant by up to 6.7 million kW. 

 

Prime example of the German energy transition 

The high level of efficiency of the plant provides numerous advantages to operators, customers and the environment: Simultaneous generation of electric power and heat can conserve up to 35% of the primary energy utilized as well as reduce CO2 emissions by 60% – concretely this represents more than 11,000 tons per year. The plant’s low natural gas consumption likewise provides savings in annual operating costs. The reduced environmental effects of the cogeneration plant in Stapelfeld make a valuable contribution to the implementation of dedicated climate protection goals of Germany and the Hamburg metropolitan area. Country-wide, by 2030 CO2 emissions should be reduced by 40% compared to 1990, and Germany’s energy efficiency should be improved 2.1% annually. At the same time, the proportion of electric power generated by CHP systems should increase to 25%.
