This study proposes a new concept called the cascade Rankine cycle, which recovers LNG (liquefied natural gas) cold energy for power generation, optimizes the cycle by investigating the effects of key parameters on its performance, and compares its thermal efficiency, exergy efficiency and...

Based on the need to reduce CO2 emissions and minimize energy dependency, the EU Member States have set ambitious energy policies goals and have developed respective, specific regulations, in order to improve the energy performance of the building sector. Thus, specific measures regarding the...

Coalbed methane (CBM) is a kind of unconventional natural gas. China has abundant CBM resource and its CBM industry is expected to prosper in the future. However, China’s currently imperfect CBM industry policy still needs to be further improved to support the sustainable development of CBM...

Cogeneration plants, which simultaneously produce electricity and heat energy, have been introduced increasingly for commercial and domestic applications in Korea because of their energy efficiency. The optimal plant configuration of a specific commercial building can be determined by selecting...

An approach for minimisation of the capital costs and energy consumption in a district heating network is presented using a case study based on a district heating network in South Wales, UK. A number of different design cases were simulated using the PSS SINCAL, taking into account different...

This paper analyzes the possibility and the cost of using gas from biomass gasification in the production of electricity and generation of heat using a piston engine in which the power in the supplied biomass is no more than 50 MW. A mathematical model that allows for thermodynamic and economic...

The impact on CO2 emissions of integrating new technologies (a biomass-to-Fischer–Tropsch fuel plant and a post-combustion CO2 capture plant) with a complex refinery has previously been investigated separately by the authors. In the present study these designs are integrated with a refinery...

To allow a real penetration of the huge dispersed naturally renewable resources (wind, sun, etc.) intermittent and more or less easily predictable, optimal sizing of hybrid renewable power generation systems prove to be essential. This paper recommends an optimal sizing model based on iterative...

Oxy-fuel technology is one of the potential solutions to reduce CO2 emissions from coal-fired power plants. Although vendors offer a “retrofit package,” to the best of our knowledge there has not been a study undertaken that looks at the technical and economic viability of oxy-fuel...

The Colombian government has defined the use of bioethanol as a gasoline enhancer to reduce greenhouse gases, gasoline imports, and to boost the rural economy. To meet the projected fuel ethanol demand needed to oxygenate the gasoline in the whole country, the construction of about five...
