Energy Recovery & DHC
The ETEKINA project has reimagined a decades-old technology called heat pipe heat exchangers. The technology allows companies to re-use the heat they generate. So far three sites that installed the prototype technology have slashed their fuel costs by 40%. Professor Ussam Jouhara, a professor of thermal engineering at Brunel University London, is the technical coordinator of the project. He shares his thoughts about the project with ESCI and his thoughts on the technology. "The principle is around forty years old. You must have a proper understanding of the chemistry. You must understand to ensure this is something that will make a proper business case to any company that will adopt it" "It is a real pleasure working closely with our manufacturing company in Wales in the UK to develop the capabilities of manufacturing those heat pipes," he says.

Small systems, big benefits
Rising gas prices and higher carbon costs are driving demand for waste heat recovery. ETEKINA has designed three heat pipe waste heat exchangers recovering 40 percent of the waste heat in the exhaust streams at each of the four facilities.

The transformation of energy intensive industries
The ETEKINA project aims to recover 57-70% of the waste heat stream in energy intensive industries which up to now just go out of the chimney. The new heat pipe heat exchangers are an efficient tool to recover heat from industrial processes.

Cleaning up “dirty” ceramic tile production
Carbon dioxide emissions are a common issue for many intensive-energy industries. But Ceramics companies are increasingly turning to creative solutions to reduce their climate footprint. Ceramic tile manufacturing industry does not have a reputation for being exactly environmentally friendly.

Deep decarbonisation of industry: The cement sector
Fossil fuel combustion to meet heating needs accounts for 35% of cements CO2 emissions. The remaining 65% are due to direct process emissions, which must also be addressed. By 2050, cement production in the EU is expected to remain below pre-2010 levels.

Recycled factory heat benefits industries and the environment
EU funded research is closing the circle with novel systems that recover waste heat and return it for reuse. Most process heat is lost to the environment as exhaust or discharge streams. Recovering and reusing this heat reduces energy consumption, emissions and pollutants.

Decarbonisation of industrial heat: The iron and steel sector
Achieving deep decarbonisation by 2050 is only possible through new production processes. Electricity demand of the sector could increase three-fold by 2050. The production of steel from recycled scrap increases by a range of +30% to +70% versus.

5 energy sources you have never thought of
Less than 30% of the energy consumed on the planet is converted efficiently. The rest is discharged into the atmosphere in the form of waste heat. Excess heat produced by chillers in a supermarket can end up providing space heating and hot water for flats.
