While industry faces rising energy costs and pressure to decarbonize, one of its most valuable resources often goes unused: waste heat. With its innovative buoyancy technology, ENERGY TOWERS presents a groundbreaking solution for converting thermal energy from energy-intensive sectors directly into CO₂-free electricity.
Waste Heat: From Byproduct to Fuel for the Energy Transition
Sectors such as the cement, steel, and chemical industries generate enormous amounts of heat as a byproduct. Until now, this potential has often gone to waste, dissipating unused into the atmosphere. This is where ENERGY TOWERS comes in: The system uses the available waste heat as the initial energy to power the towers through a physical buoyancy process.
Zeki Akbayir, founder of ENERGY TOWERS, explains: “Our technology uses proven mechanical engineering principles with a new twist to generate a constant flow of electricity from industrial waste heat, ensuring the base load capacity of industrial plants.”
Scientifically sound and market-ready
The efficiency of the underlying subsystems has already been analytically investigated in collaboration with the Karlsruhe Institute of Technology (KIT). The calculations show promising efficiency levels: While the hydraulic system achieves a target efficiency of 68%, the “Tower” subsystem achieves values of up to 87% with optimized cycle times. As a result, ENERGY TOWERS achieve a system efficiency of 25% and offer up to 8,000 full-load hours per year.
Benefits for industry and municipalities:
- 100% CO₂-free: no combustion of fossil fuels, no direct emissions.
- 24/7 availability: Unlike wind and solar power, electricity generation using waste heat and buoyancy is completely weather-independent and capable of providing baseload power.
- Scalability: from 100-kW standalone systems to 5-MW modules that can be flexibly installed at factory sites or in microgrids.
- Equity & Autonomy: Decentralized energy supply reduces dependencies and makes clean electricity available where it is needed.
