The energetic and environmental performances of building cooling heating and power (BCHP) system are closely dependent on its design and operation strategy. This paper analyzes the energy consumptions of a conventional separation production (SP) system and a BCHP system respectively and...

Due to better wind conditions at sea, offshore wind farms have the advantage of higher electricity production compared to onshore and inland wind farms. In contrast, a greater material input, leading to increased energy consumptions and emissions during the production phase, is required to build...

The knowledge of the potentially achievable reduction of greenhouse gas (GHG) emissions by biomass co-firing is a powerful tool in supporting decision makers when it comes to undertaking energy planning. The main goal of this work was to develop a methodology by which significant biomass...

Biomass CCHP (combined cooling heating and power) systems based on biomass combustion have already demonstrated their benefits in some operating conditions. However, their environmental and energy performance might not always be better than that of conventional stand-alone generation systems. In...

One way of producing nearly CO2 free electricity is by using biomass as a combustible. In many cases, removal of CO2 in biomass grown is almost the same as the emissions for the bioelectricity production at the power plant. For this reason, bioelectricity is generally considered CO2 neutral. For...

This paper presents the results of exergetic and environmental analysis of a typical pulverized coal power plant located in Brazil. The goal was to quantify both the exergy destruction and the environmental impact associated with a thermal power plant. The problem boundary consists of the entire...

Environmental information obtained through Life Cycle Analysis techniques has been incorporated into a Mixed Integer Linear Programming (MILP). The solution of the model provides the optimal configuration and operation of an energy supply system to be installed, minimizing the environmental...

In recent years, there has been a growing increase of the cooling demand in many parts of the world, which has led to major energy problems. In this context, solar assisted absorption cooling systems have emerged as a promising alternative to conventional vapor compression air conditioning...

Multi-objective optimization (MOO) is increasingly being used in a wide variety of applications to identify alternatives that balance several criteria. The energy sector is not an exception to this trend. Unfortunately, the complexity of MOO grows with the number of environmental objectives....

The environmental impact associated with a SOFC (solid-oxide fuel-cell) power generation system has been assessed using a LCA (life cycle assessment) method. LCA is a technique assessing the environmental aspects associated with a system during its entire life cycle. To calculate the...
