Research

At the RES, high-temperature solid oxide electrolysis cells (SOEC) for use in a PtX pilot plant are being investigated. SOECs are used to generate hydrogen gas (and/or carbon monoxide) and oxygen from water (and/or carbon dioxide). The advantage of the SOEC for generating hydrogen from water is its high conversion efficiency.

The RES examines the economic-ecological effects of electricity fuels.
Life-Cycle Assessments (LCA) are used to map the environmental effects of synthetic fuels over their entire life cycle, taking into account the dynamic development of the energy system. The determination of eco-efficiency data also allows the comparison of synthetic fuels with regard to their economic-ecological impact.

Dynamic Life-Cycle Assessments (LCA) and eco-efficiency of electricity fuels

At the RES the ecological and the economic-ecological effects of electricity fuels are examined. For this purpose, the Life-Cycle Assessment (LCA) method according to DIN EN ISO 14040 and 14044 and an eco-efficiency analysis are used. First, with the help of a dynamic LCA, the environmental impacts of synthetic fuels are to be examined over their entire life cycle, taking into account the dynamic development of the energy system. This enables the ecological advantages of synthetic fuels to be analyzed compared to other, for example fossil, energy sources. The combination of ecological indicators from the LCA with economic indicators results in the so-called eco-efficiency, allowing synthetic fuels to be compared in terms of their economic-ecological impact.

The aim of the work at the RES, is not only to balance synthetic fuels, but also to build on the environmental impacts of various future scenarios of traffic composition.

Biogas COnversion with Reversible Electrolysis

Validation of a reversible, highly efficient, biogas-operated solid oxide cell system

In the BioCORE project, a technology for generating electricity from biogas with high electrical efficiency is to be validated as part of a prototype system, also to simplify scale up and to promote the commercialization of the process.

Solid Oxide Fuel Cells (SOFC) are applied, which exhibit a superior efficiency. By means of a novel system architecture the efficiency of the SOFC system is supposed to rise significantly compared to start-of-the-art concepts, while at the same time allowing reversible operation. This means that also excess electrical energy from wind power and photovoltaics can be transferred into synthetic methane and stored in the existing natural gas grid. Hence, the same system is capable of generating electricity from biogas and acting as a storage for fluctuating renewable electricity, both at very high efficiency. After completion of the project the realization of a pilot plant with economically viable capacity will be addressed.
