Life cycle analysis of energy consumption of distributed energy system projects and GHG emission - A case of auxiliary power supply of brewery in China

The project referred to in the article corresponds to a research on energy saving and emission reduction, which compares the cases in which energy is generated from coal and grid electricity, in contrast to the project of the Energy System Distributed energy based on gas saves 8% of energy and reduces GHG emissions by 38% in the data obtained through life cycle analysis. It can be concluded that renewable energy offers alternatives to reduce GHG emissions.
Subsequently, the results are compared with other renewable energy alternatives, analyzing the life cycle of their production and finding that around the project site, solar energy can hardly improve performance. However, it is possible to use biomass or wind energy in the distance to improve the system. Find that both have great potential in the development of Distributed Energy System projects.

ISO 14040 standard that details the Requirements to carry out an LCA, life cycle analysis.

The LCA deals with the environmental aspects and potential environmental impacts (for example, the use of resources and the environmental consequences of emissions) throughout the life cycle of a product from the acquisition of the raw material, through the production , use, final treatment, recycling, until its final disposal (that is, from the cradle to the grave).

There are four phases in an ACV study:

1) the definition phase of the objective and the scope,

2) the analysis phase of inventing

3) the environmental impact assessment phase, and

Regarding the NTC 14040 which is focused from the local perspective and ISO 14044 representing the International Organization for Standardization. We can clearly identify the importance of a descriptive analysis in which the root cause of the impacts associated with the integration of a product in a productive process is sought.

Framework.

The analysis of the life cycle (LCA), Study of the aspects of the media and the long-term impacts of the life cycle of a product or activity.

It is based on the origin of the raw material until the end, that is, taking into account the intermediate materials such as transport, preparation and transformation of raw materials.

The ISO 14044 standard requires the identification and evaluation of environmental impacts during all stages of the life cycle: extraction, production, distribution, use and waste.

It allows identifying with the environmental analysis improvement opportunities that help reduce costs.
