Innovative energy solutions: Cottbus researchers are driving a CO2-neutral future!

The transition to carbon-neutral energy solutions is currently experiencing a significant boost, particularly through innovative technologies such as Power-to-X (PtX). At the Brandenburg Technical University (BTU) Cottbus-Senftenberg, a groundbreaking approach is being pursued with a new system demonstrator for Power-to-X-to-Power (P2X2P). Dr. Rufat, a researcher in the Energy and Conversion (ESC) Lab, is studying the diverse possibilities of oxy-methane combustion in a single-cylinder gasoline engine to research and promote the benefits of these technologies. The aim is NOx-free heat and electricity generation in a CO2-neutral closed circuit that does not produce harmful emissions, reports the BTU.

In the studies, synthetic methane is produced from green hydrogen obtained by electrolysis of water and separated CO2. This environmentally friendly method uses electricity that comes primarily from renewable energy sources. The methane produced is processed in the so-called Sabatier reactor before it is used in the oxyfuel combustion process to generate electricity. The research also addresses the effects of different dilution levels and compositions of oxygen, carbon dioxide and water on important parameters such as cylinder pressure, cylinder temperature and emissions during the work cycle.

Innovations in the energy sector

The increasing demand for alternative energy sources is also leading to greater interest in green fuels derived from renewable energy. This includes not only green hydrogen, but also alternatives with higher energy density such as e-methanol and e-ammonia. These e-fuels combine renewable hydrogen with carbon and nitrogen to meet growing energy needs in less adaptable industries such as shipping and aviation, explains Ørsted.

Another important aspect of PtX technology is that it helps create a flexible and integrated energy system. This technology complements existing utility sectors such as electricity, gas and heating, paving the way for greater integration of renewable energy. Eurowind Energy and other companies are actively working on projects that further develop the hydrogen and energy storage value chain to support this transition, Eurowind Energy reports.

Strategic developments

As part of the PtX projects, strategic partnerships have been formed with key players such as the Green Hydrogen Hub and Greenlab Skive. The aim of these initiatives is to integrate renewable energies into existing networks and to develop new technologies for energy production and storage. In Denmark, projects are also being worked on to optimize the district heating supply using heat pumps and green energy.

The results of the studies at the BTU Cottbus-Senftenberg are promising. Research shows that a CH4/O2/CO2 mixture enriched with water vapor alters combustion parameters compared to conventional air services and enables significant emissions reductions. The ability to efficiently generate energy under different conditions can significantly increase the competitiveness of storage and hydrogen refining technologies.

In summary, the combination of research, technological innovations and strategic partnerships makes a significant contribution to the development of carbon-neutral energy solutions. The diverse approaches to producing, storing and using green hydrogen and its derivatives are crucial for transforming energy supplies and reducing fossil fuels.
