Abstract: Thermal energy loss in the process industry is a significant issue due to the high temperatures and multiple heat intensive processes involved. High-grade thermal energy is typically recovered within processes. However, lower grade heat is often rejected to the environment. The benefits of capturing and utilising low grade thermal energy are highly dependent on the qualities and properties of the heat in the waste streams. The temperature of the low grade heat stream is the most important parameter, as the effective use of the residual heat or the efficiency of energy recovery from the low grade heat sources will mainly depend on the temperature difference between the source and a suitable sink, e.g. another process or space heating/cooling. In general, the temperatures of these waste heat sources are too low to produce electricity and direct heat use will depend on whether potential user can be found. This paper presents past and current drivers for heat recovery studies. High and low grade heat sources are defined according to the viability of recovery within the processes. Firstly, high grade heat capture within the processes is reviewed. Then, the focus is on the potential for low grade heat capture outside of the original plant. The paper addresses the potential for low grade heat recovery with regard to new incentives and technological advances. Finally, different aspects which influence the decision making for low grade heat recovery in the process industry are discussed. It is concluded that organisational, financial and economic barriers might be overcome and benefits from a holistic vision could be gained with stronger governmental policy and regulation incentives.

Abstract: This paper presents the strategy of the European Union in the field of energy and climate change. At the heart of the package are three commitments to be met by 2020: to reduce greenhouse gas emissions by at least 20%, to ensure that 20% of final energy consumption is met with renewable sources, and to raise energy efficiency by 20%. This strategy is based on the scientific consensus drawn by the International Panel for Climate Change, and implements the EU political strategy to limit the anthropogenic temperature rise to no more than 2 °C. A Directive for the geological storage of CO2 is another integral part of the package. This should enable the development and subsequent deployment of zero emission power plants. From a research and technology perspective, the Strategic Energy Technology Plan (SET-Plan) lists several energy technologies which will be required to reconcile economic growth and a vision of a decarbonised society. The EU climate and energy package and the SET-Plan are part of the solution both to the climate crisis and to the current economic and financial crisis. They represent a green “new deal” which will enhance the competitiveness of EU industry in an increasingly carbon-constrained world. [Copyright &y& Elsevier]
