Impact

Economic

The successful development of the Indus3Es project will make possible to offer to the market a competitive sustainable solution for reducing significantly the energy use in the industry. This system has the potential of saving up to 20% of energy consumption and an increase of energy efficiency by 25%. There are industries where these values will be even higher but some others in which expected savings may be lower. See the chart below for possible waste heat revalued potential:

The waste heat from European industrial production have a potential value of up to 4.250 M€ for the European industrial sector (having a process efficiency of 70%).

Studies will be carried out through the project to maximize the future commercialization and exploitation of the developed technology and system. Payback is expected to be between 2 and 4 years, depending the process, fulfilling industry requirements in terms of economic feasibility. Nevertheless each process will require a specific solution, thus, a tailor-made design will need to be prepared. During the project the AHT technology will be demonstrated in a real environment, under working conditions of a Tüpras’ refinery.

Environmental

The Project is focused on energy intensive industries which have a large influence on the environment. The development of the AHT technology can contribute to the EU objective of reducing by 20% the energy consumption with further reduction in greenhouse gases emissions and also would have a positive effect on the reduction of primary energy consumption.

Therefore, the Indus3Es project will have environmental impact on:

  • EU’s decarbonisation ambitions
  • Breakthrough solutions for advanced low-carbon industry-processing
  • Improving the competitiveness of EU industries by developing ready -to-market penetration of AHT systems
  • Eliminating current barriers for waste heat recovery
  • Making AHT more attractive through significant reduction of operational, maintenance and installation costs

Technological

Brief on Absorption Heat Transformer (AHT) technology

The technology in focus in the Indus3Es project is the absorption heat transformer technology.

The single effect heat transformer technology is effectively a single effect absorption chiller working in reverse mode. It consists primarily of one condenser, one evaporator one absorber and one generator.

Single effect heat transformers can increase the temperature of approximately 50% of the waste heat by up to 50 K (depending on the available heat sink).

In contrast to absorption chiller, in a heat transformer absorber and evaporator operate at high pressure than condenser and generator. Waste heat is fed into the evaporator and generator and upgraded/revalued heat at an increased temperature level is extracted from the absorber.

AHT and Indus3Es

In the Indus3Es project the heat source is waste heat.

Indus3Es Process

Indus3Es System will be able to recuperate low-temperature waste heat from industrial processes which is currently useless.

Indus3Es system is capable of raising temperature of low-grade heat (in the range of 70-100ºC) by about 50 K, yielding a COP of 0.5 approximately.

The AHT’s useful effect of temperature boosting is obtained by the absorbent solution’s thermo-physical properties in the Absorber. The thermodynamic cycle is activated by waste heat fed into the Evaporator and Generator.

Social

Energy-efficiency catalyses employment opportunities. Companies’ investments in energy efficiency improve their experience and increase competitiveness. This is a potential contributing factor to bringing jobs back.

US economy estimates states that by investing and deploying existing and more advanced technologies has a potential of a net increment of 1.3 to 1.9 million jobs by the year 2050.

Energy efficiency stimulates economic activity and it is a key driver to a more robust and abundant economy. This will be studies and analysed through the project investigating future scenarios of social impact.

The Indus3Es project will contribute to the public awareness on climate change, sustainability and the importance of energy efficiency technologies for society as long term solutions to climate change.
