Cottbus in focus: Tech congress on clean energy starts soon!
Cottbus, the heart of Lusatia, will be the venue for the “Decarbon Days” from June 26th to 28th – a tech congress that deals with the future topics of clean energy. Over 30 experts from politics, science and business will come together at this important event, which takes the pulse of the changing times and discusses the role of clean technologies for innovation and competitiveness. Niederlausitz Aktuell reports that the congress will take place in a former aircraft hangar where the future planned Lausitz Science Park is to be built.
It starts with the EU summit “EU meets Net Zero Valley”, attended by politicians such as Dr. Christian Ehler and Kerstin Jorna will take part. Important impulses for future energy policy are set here and the course is set for the next steps towards a climate-neutral future. On June 27th, the program includes panels, workshops and the award ceremony for the Female Energy Awards, an initiative to recognize female innovators in the areas of clean energy and technology.
Diverse topics and discussions
The topics of the tech congress are as diverse as necessary. A central concern is the discussion about applied energy research to support the Net Zero Industry. The focus here is particularly on 100% renewable energy supply for both the present and the future. Decarbon Days shows how technologies in Lusatia can be combined to provide diverse energy supply services, including innovative digital planning tools to transform the regional heating infrastructure.
The contribution of the heat transition to the overall strategy of the energy transition is also discussed in detail. A reference power plant in Lusatia, which is the first power plant to be based entirely on renewable energy, is a shining example.
Challenges and opportunities for the EU
The “Decarbon Days” will also take a look at the current challenges and opportunities affecting European industry. A recent assessment of key technologies for climate-neutral energy shows that the EU is excellently positioned in areas such as wind energy and heating and cooling networks. According to a report by the Joint Research Centre, the EU has improved its production capacity in many areas in recent years and is showing increasing innovative strength. However, the challenge remains, particularly in the commercialization of these technologies, which is lagging behind expectations.
The presentation uses and analyzes key economic data to measure the EU's competitiveness compared to other global players. While the positive trend in patents and public research investment is notable, there are concerns about the rise in imports and trade deficits in key technology areas.
A talent day to strengthen exchange
The crowning conclusion of the “Decarbon Days” is the Talent Day on June 28th, which is organized in cooperation with the University of Zielona Gora and the BTU Cottbus-Senftenberg. In addition to job dating and political talk, the finale of the Climathon also takes place here, where creative solutions to cleantech challenges are sought. This not only promotes exchange between experts, but also encourages the next generation of innovators to take an interest in sustainable technologies.
The “Decarbon Days” are intended to become an annual platform for cleantech start-ups and political actors in Europe. An ambitious goal that is all about a more sustainable and innovative future. With all of these developments, it is clear: Cottbus is well on its way to becoming a center for green technologies.
