Within the carbon constrained world, biomass-based power production is expected to constitute one of the candidates for CO2 abatement. However, within the framework of a liberalised energy market, biomass power systems must be competitive from efficiency and cost point of view for their...

The need for a practical, economic and environmentally sound solution for waste wood arises from the requirements for resource conservation and recent regulations. Co-firing with coal is a promising option for the thermal recycling of waste wood. The overall environmental impact caused by the...

Up to recently 2-D solid oxide fuel cell (SOFC) modelling efforts were based on global kinetic approaches for the methane steam reforming and water gas shift reactions (WGS) or thermodynamic equilibrium. Lately detailed models for elementary heterogeneous chemical kinetics of reforming (HCR)...

This paper presents the energy policy of the Republic of Cyprus government controlled areas from 1960 till 2006. It describes the sectors of electricity, petroleum, natural gas and renewable energy sources. It also deals with the marine layers of oil and with environmental aspects.

In a typical cement producing procedure, 25% of the total energy used is electricity and 75% is thermal energy. However, the process is characterized by significant heat losses mainly by the flue gases and the ambient air stream used for cooling down the clinker (about 35%–40% of the process...

This paper presents an exergetic analysis of a combined heat and power (CHP) system, integrating a near-atmospheric solid oxide fuel cell (SOFC) with an allothermal biomass fluidised bed steam gasification process. The gasification heat requirement is supplied to the fluidised bed from the SOFC...

The generated power and efficiency of gas turbine plants depend on the temperature of the inlet air. At high ambient temperatures, a power loss of more than 20%, combined with a significant increase in specific fuel consumption, compared to ISO standard conditions (15 °C), can be observed.

The use of biomass, wood in particular, is one of the oldest forms of producing energy for heating or cooking. Nowadays, new technologies concerning the utilisation of biomass or waste residues are in demand and the trend to use them in decentralised applications for combined heat and power...

The pre-combustion carbon capture technology based on coal gasification or methane reforming followed by (water gas shift reactors assisted with Pd-alloys membranes) WGS-MR is considered very promising for the production of a rich hydrogen stream that can be combusted in combined cycles....

Coal and lignite will play a significant role in the future energy production. However, the technical options for the reduction of CO2 emissions will define the extent of their share in the future energy mix. The production of synthetic or substitute natural gas (SNG) from solid fossil fuels...
