MaTiC-M" Methods and Technologies for an intelligent Circularity of Materials
The main scope of the project: Circularity and the development of sustainable designs for technologies - so called Designs-for-Circularity - gain in importance, due global climate change. Approximately 80% of the enviornmental impact of a product originate from its design-phase. Currently, increasing efficiency and performance during use-phase consitutes the core of product development, e.g. by reducing weight of components or whole systems. This is one important reason why waste material is often unsuitable for recycling.
The decommissioning of coal-fired power plants is economically challenging, but nevertheless necessary for climate protection reasons. Iron as an energy carrier could give a second life to existing plants, while decarbonizing the power generation. In a two-step process, energy from renewable sources can be stored into iron particles and later released through dust firing. IronCircle® is DLR's answer to bring this concept into practical applications.
The acronym SPIRIT stands for "Implementation of sustainable heat upgrade technologies for industry". Behind it is a consortium consisting of 17 partners, including three research institutions (one of them DLR). The aim of the EU-funded project is to demonstrate stable and safe operation of three full-scale high-temperature heat pumps in a sugar factory, a shrimp processing plant and a paper mill.
In the development of new types of products, there are usually many requirements for highly stressed components. These can occur, for example, in terms of structural mechanics, aerodynamics or coupling and therefore represent major hurdles in engineering. Since the evaluation can usually only be provided by hardware-intensive simulations, the design process is usually iterative with the help of optimization methods.
The Institute of Low-Carbon Industrial Processes is developing a high-temperature heat pump (HTWP) based on the Rankine process (working medium water/steam) and will set up the corresponding DLR test facility ZiRa for this purpose.
In the project "Prepilot ZiRa", the department for high-temperature heat pumps of the Institute of Low-Carbon Industrial Processes is investigating the special features of water vapor compression, which is a central element in the design of a high-temperature heat pump.
