Solutions
Electrifying Industry,
One Solution at a Time
EEETHOS develops key enabling technologies to replace fossil-based heating in industry with electrified, high-efficiency systems. These technologies are demonstrated in five industrial sectors and offer scalable solutions for the entire European process industry
Why These Industries Matter?
EEETHOS targets five of the energy-intensive sectors—Asphalt, Ceramics, Pulp & Paper, Bricks, and Steel—that rely heavily on high-temperature heat, typically above 150°C, and continue to rely predominantly on fossil fuels. Existing electrification technologies often fall short of meeting these temperature requirements, leaving a critical gap in the path toward industrial decarbonisation.
Each sector faces distinct energy and operational challenges, from moisture-intensive drying in bricks and asphalt to the extreme -heat release in steel casting. EEETHOS delivers tailored high-efficiency technologies to replace fossil fuels with electricity, recover waste heat, optimize current equipment, thereby reducing emissions, and demonstrating scalable solutions across Europe.
Our Demonstrators
EEETHOS targets five energy-intensive sectors
Asphalt
For the asphalt industry, EEETHOS will demonstrate a drum dryer integrated with a cascade high-temperature heat pump (HTHP) using hydrocarbons and a screw steam compressor to dry and heat the asphalt.
This system replaces over 70 kWh of natural gas per ton of material with just 23.7 kWh of electricity, delivering up to 200°C steam and achieving energy savings up to 67%
Steel
In the steel industry, EEETHOS focuses on recovering radiative waste heat from slab cooling. The demonstrator will harness up to 1 MW of thermal energy, which can be reintegrated into the process or potentially used for preheating scrap metal or supporting carbon capture technologies.
Bricks
For the brick manufacturing process, EEETHOS will showcase a hybrid drying approach that flexibly switches between hot air and superheated steam.
This approach enables significant energy savings or faster production cycles, reducing energy use to as low as 0.15 kWh/kg and drying times from several days to under 30 hours.
Ceramics
The ceramic demonstrator will implement a reverse Brayton cycle HTHP using turbocharger components to recover waste heat from kiln exhaust.
This system provides up to 1 MW of heat at 300°C, significantly cutting gas consumption while offering a modular and scalable solution adaptable across the ceramic sector.
Pulp & Paper
In Germany’s pulp and paper sector, EEETHOS will install a steam-generating HTHP equipped with two-stage turbo compressors to replace fossil-fueled steam systems.
Capable of delivering 1 MW of steam at 10 bar and 180°C, this system achieves a coefficient of performance (COP) of 2.1, ensuring high energy efficiency.
