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: Energy and climate change is a key priority issue mentioned by the Mediterranean Strategy for Sustainable Development (MSSD) which explicitly claims that “Control, reduce or stabilize GhG (Greenhouse Gas) emissions” is a crucial target for Mediterranean countries. This paper uses the integrated assessment model IFs (International Futures) to implement a scenario analysis to investigate the mitigation potential of Mediterranean regions. It analyzes if the Mediterranean regions will be able to reach the MSSD climate change target and recommends amendments of the MSSD to implement with effectiveness climate change policies in the Mediterranean area.

This paper argues that the most obvious measure to combat greenhouse gas emissions is to remove the vast subsidies that promote higher energy consumption in more than half of the countries in the world, and that this measure should take precedence over many others. The article discusses also why removing energy subsidies is so difficult, and which type of state may succeed. This question is examined with reference to China, India and Russia, all major contributors to global warming. Non-democratic governments and energy importers might be expected to be more likely to halt subsidies. In fact, energy trade imbalances do not seem to significantly affect the capacity to reduce subsidies. The risk of social unrest is a political restraint in all three countries. Perhaps surprisingly, democratic states may be better positioned to remove subsidies than non-democratic ones. [ABSTRACT FROM AUTHOR]

Climate change, due to anthropogenic emissions of greenhouse gases, is driving policymakers to make decisions to promote more efficient energy use. Improved industrial energy efficiency is said to play a key role in the transition to more carbon-neutral energy systems. In most countries, industrial small and medium-sized enterprises (SMEs) represent 95% or more of the total number of companies. Thus, SMEs, apart from using energy, are a major driver in the economy with regard to innovation, GDP growth, employment, investments, exports, etc. Despite this, research and policy activities related to SMEs have been scarce, calling for contributions in the field. Therefore, the aim of this paper is to critically assess how adequate energy efficiency policy programmes for industrial SMEs could be designed. Results show that scientific publications in the field differ in scope and origin, but a major emphasis of the scientific papers has been on barriers to and drivers for energy efficiency. Scientific contributions from studies of energy policy programmes primarily cover energy audit programmes and show that the major energy efficiency measures from industrial SMEs are found in support processes. The review further reveals an imbalance in geographic scope of the papers within the field, where a vast majority of the papers emanate from Europe, calling for scientific publications from other parts of the world. The study synthesizes the findings into a general method on how to design efficiency programs for the sector. [ABSTRACT FROM AUTHOR]
