Understanding the exergy of cold: theory and practical examples
Exergy analysis is used to evaluate the thermodynamic performance of processes, including energy conversion and supply systems. This often involves the calculation of the exergy of heat, at a temperature either above or below the environmental temperature (T0). The exergy of 'cold', i.e., heat at T Keywords: exergy of cold, cool exergy, exergy analysis, exergy factor, cool exergy potential, ...

The new scope of knowledge spillover to develop the functionality of technologies
The purpose of this study is to propose a new scope of knowledge spillover between technologies by demonstrating how knowledge spillover affects the development of technologies. We use the number of patent applications as proxy of development of technologies. As a case of this study, we group energy technologies, lithium-ion battery (LIB) as a product, into two groups using international patent ...

Development trends in the Estonian energy sector at transition
1994 can be considered as the first year of the transition period in the Estonian energy sector when Estonia signed the Energy Charter and recognised European energy cooperation principles. The process in the energy sector reached its peak in 1998 when the Energy Act was enforced and the Estonian Parliament approved the Long-Term National Development Plan for the Fuel and Energy Sector. Reaching ...

Technological innovations and energy intensity of machine tool SMEs in Bangalore: do process innovations contribute to energy efficiency?
This paper explores the relationship between technological process innovations and energy intensity growth of small and medium enterprises (SMEs) in the machine tools industry of Bangalore, India. It empirically substantiates that SMEs, which carry out process innovations with the objective of cost reduction are able to achieve reductions in their energy intensities, over a period of time. Apart ...

Synergistic energy conversion processes using nuclear energy and fossil fuels
This paper reviews the methods of producing energy carriers, such as electricity, hydrocarbons and hydrogen, by utilising both nuclear energy and fossil fuels synergistically. There are many possibilities for new, innovative, synergistic processes, which combine chemical and nuclear systems for efficient, clean and economical production of energy carriers. Besides the individual processes by each ...

Long-term global vision of nuclear-produced hydrogen
Nuclear energy is the number one candidate to provide the backbone of primary energy procurement for humanity in the present century and beyond. Uranium fuel is abundant, and could become unlimited in the scheme proposed here, making nuclear energy sort of renewable. However, the only vector of nuclear energy now is electricity, which may finally consume half the primary energy input. The market ...

Multi-regional technological learning in the energysystems MARKAL model
This paper describes the implementation of multi-regional endogenous technological learning in the energy optimisation MARKAL model. A mapping procedure is implemented to group learning technologies inside one region or across several regions in a flexible way, in order to allow them to learn together. The approach is described and an illustrative example examining the response of a ...

Actions to promote energy-efficient electric motor repair
Electric motors are repaired 2-3 times over their lifetime. Poor repair practices, particularly widespread in developing countries, can lead to a significant increase in motor losses. It is estimated that worldwide poor repair leads to annual electricity losses of approximately 40 TWh, representing 20 Mtons of CO2 emissions. The main objective of this paper is to provide a technical basis for ...

Exergy use in bioenergetics
Every developed and adapted biological system extracts useful energy from outside, converts, stores it, and uses for muscular contraction, substrate transport, protein synthesis, and other energy utilising processes. This energy management in a living cell is called the bioenergetics, and the useful energy is the exergy, which is destroyed in every irreversible process because of the entropy ...
