MEIKE

A fully renewable energy system requires technologies that can store large amounts of energy efficiently over the long term. The MEIKE project is investigating a promising approach based on the cyclic oxidation and reduction of iron, which can continue to use existing infrastructure in the form of power plants.

The focus is on the further development of key components of conventional power plants in order to use the oxidation of iron dust for efficient electricity and heat generation. These include burners, steam generators, and systems for separating iron oxide dust from exhaust gases. Based on this work, conversion concepts are being developed for two types of power plants – an inner-city cogeneration plant with heat utilization and a large power plant without heat extraction. Infrastructure, legal, and economic aspects such as fuel storage and transport are also being taken into account.
