"Revolutionizing Cement: Orcan Energy, E.ON, and Holcim Turn Waste Heat into Clean Power at Dotternhausen"

Revolutionizing Cement: Turning Waste Heat into Clean Power at Dotternhausen
At the heart of Germany’s industrial sector, a quiet revolution is taking place—one that could redefine how we think about energy in heavy industries. 

In the town of Dotternhausen, a cement plant is transforming its waste heat into valuable clean electricity, thanks to a bold collaboration between three innovative players.
⚙️ The Power Trio Behind the Breakthrough
An advanced energy technology firm has introduced a cutting-edge Organic Rankine Cycle (ORC) turbine capable of converting industrial waste heat into electricity, even under fluctuating conditions. This system has been installed at a major cement plant known for its high energy demands.
What makes this project unique is the model behind it. Rather than requiring the cement plant to invest heavily upfront, a trusted energy infrastructure company is providing the entire system through an Energy-as-a-Service (EaaS) approach. They manage everything—from planning and financing to construction, operation, and maintenance—so the plant can focus on its core business while enjoying clean energy and cost savings.
This forward-thinking collaboration also benefits from government support, showing strong institutional confidence in scalable climate tech solutions.
🔥 Waste Heat: An Untapped Goldmine
Cement production is notoriously energy-intensive, and most of that energy ends up as waste heat. Traditionally, this heat is vented into the atmosphere. But with the ORC turbine now in place, that waste becomes a powerful asset—converted into clean electricity that reduces operational costs and carbon emissions alike.
The technology stands out for its flexibility. It doesn't need a constant, high-temperature heat source to function. Even when heat levels drop, the system continues to operate efficiently, making it perfect for the unpredictable nature of industrial heat flows.
🌱 A Big Step Toward Decarbonization
This is more than just a technical upgrade—it's a strategic leap toward sustainability. By capturing waste energy and converting it into power, the cement plant significantly reduces its carbon footprint. Even more impressive: it accomplishes this without committing capital expenditure, thanks to the service model backing the project.
The financial and environmental advantages are clear:
  • Lower electricity costs
  • Reduced CO₂ emissions
  • No upfront investment
  • Maintenance handled by experts
  • Long-term energy resilience
🔧 A Blueprint for the Future of Industry
This project is more than a success story; it’s a replicable model. It proves that even in hard-to-abate sectors like cement, practical, scalable solutions exist for cutting emissions and enhancing efficiency. And it shows how collaboration between tech innovators, infrastructure experts, and industry leaders can unlock new energy possibilities.
As industries face growing pressure to decarbonize, the Dotternhausen example serves as a beacon. It demonstrates how waste heat—long ignored—can become a powerful tool for sustainable growth.


🚀 Ready for a New Era of Clean Industry?
This is just the beginning. The question now is: which industry will be next to unlock the potential of its waste heat?
The future of industrial energy isn’t just about cutting emissions—it’s about turning yesterday’s waste into tomorrow’s power.

INTERVIEW, Geretsried and Beyond: Eavor’s Blueprint for Reliable, Sustainable Energy

Robert Buluma :  Alphaxioms Responses were provided by Jeanine Vany, Executive Vice-President of Corporate Affairs, Eavor . Can you explain the key technological advancements in the latest iteration of the Eavor-Loop™ system? We have made a number of technological advancements at our project in Geretsried Germany . This includes innovation and learning resulting in dramatic improvements in our drilling performance and we’re proud to talk about our technology. For example, Eavor recently announced successful implementation of our in-house AMR (active magnetic ranging) tool which makes drilling more accurate and efficient. Eavor-Link™ AMR uses magnetic ranging while drilling to maintain constant alignment as it drills two wells at approximately 100 metres apart before they are intersected to create a continuous geothermal loop, which is then sealed with Eavor’s proprietary Rock-Pipe™ formula. With real-time data transmission between downhole sensors, the technology ensures tighter bo...

Driving the UK Toward Net Zero: Chris Sladen on Geothermal’s Untapped Potential

Alphaxioms, we talked to Chris Sladen about his involvement in geothermal both in the UK, and globally By:  Robert Buluma Chris, please begin by explaining a little about yourself, and why you have a passion for geothermal? I have spent over 45 years involved in energy. Following undergraduate studies in geology at Southampton University, and a PhD in sedimentology at Reading University, I joined the energy sector in Aberdeen in 1980. It was a fascinating era when it seemed like at least one giant oil & gas field was discovered offshore every month; the wealth creation for the UK was gigantic. I got to see so much geology and rocks - my true passion. I moved to China in late 1983; not today’s China, this was over 40 years ago, a country closed for decades and embarking on an open-door policy, in part to bring both investment and technology. I became very interested in energy trends, energy politics, and new geography created by changing politics leading to opportunities for ene...
