LIFE CYCLE ANALYSIS OF DISTRIBUTED ENERGY SYSTEM PROJECTS’ENERGY CONSUMPTION AND GHG EMISSION – A CASE OF BEERBREWERY AUXILIARY POWER SUPPLY IN CHINA

In the article, we can see a study of life cycle analysis where the energy consumption and GHG emissions of a distributed natural gas energy system are evaluated compared to other five cases of traditional energy types such as coal and electricity by network in China. In this way, a comparison is made between different types of energy consumption, concluding that in life cycle analysis it is possible to observe that the natural gas alternative reduces atmospheric emissions by 38% and represents the lowest energy consumption (8%) for the project is compared with other traditional energy sources, so it is possible to conclude that the best alternatives are renewable energies for the future.

So the ACV methodology is a methodology that makes an analysis of energy expenditure from the extraction of raw material to the final disposal stage of waste achieving a comprehensive assessment that allows to identify the environmental impacts generated by energy consumption.

“China, by means of the LCA method, evaluates energy consumption and gas emission; This method allows the comprehensive collection, quantification and evaluation of environmental damages related to the Resources snow Breweries natural gas distributed energy system, the coefficients may vary over time and the value of different projects are subject to demand and location of users, which shows that case Studies are important in this stream of research”.

Authors investigate: Distributed Energy, which is the generation and management of electrical energy in a decentralized manner, as close as possible to its place of consumption, mainly through renewable energy sources. They also do research on energy alternatives that are both a challenge and an opportunity. They are a future opportunity for the planet that already suffers a lot at the hands of man with CO2 emissions into the atmosphere and global warming, causing climate change; they are an opportunity to amend, or at least stop, the damage done and, above all, they are an opportunity to leave to future generations a sustainable world that does not self-destruct.

This research is based on life cycle analysis (LCA). With production (electricity, heat and refrigeration) kept constant, analyzing the input required by different technologies and comparing life cycle energy consumption and GHG emissions. The results of these cases are compared and a sensitivity analysis is carried out, yielding a policy guide.

The article reports that the differences between the Distributed Energy System and the traditional energy system are investigated by providing data on sensitivity factors (heat power ratio), although the authors emphasize that these may vary over time and that project values depend on user demand and location.

For this reason, it is important to study other cases, among them those where distributed energy systems are implemented in ecological buildings in Spain, to evaluate their performance and other factors that allow for the evaluation of their influence on the environment.

In China the projects are quite interesting because they promote the Distributed Energy System, allowing to compare different scenarios and have great evidence. In gas-based projects they are investigated with a full spectrum of aspects including economic, environmental and other values. Their economic viability is analyzed by simulating oil and gas prices and operational scenarios.

To examine the environmental performance of actual projects, a case study is conducted, comparing the project's emission and that of an alternative case where heat, cooling and electricity are provided individually, but for renewable energy projects the analysis is different, as fuel costs and emissions are small for this type of technology. Therefore, the Life Cycle Analysis method is used to analyze renewable energy projects and its results serve as a basis for future research.

In the article we announce the stages of a product; we try an environmental approach, to measure the environmental impacts from the definition of the objective to the impact evaluation and its direct applications. The level of detail and duration depends on the objective and its scope, methodologies, specific requirements are established. ACV is different because it is based on a functional unit. A highlight that ACV does not predict environmental impacts but rather treats potential environmental impacts, involving elementary movements such as water, air and soil. It also contains unit movements which carry entry and exit movements. ACV has the purpose of evaluating how important are the environmental risks that affect ICB results.

Life cycle analysis (ACV) is an environmental calculation methodology through which all the environmental aspects of a product, process or service throughout its life can be inquired and quantified. It includes all the stages of its existence, that is, the stages that go from the extraction of raw materials, its manufacture, transportation, distribution, use, reuse or recycling and the ultimate disposal of waste. The (ACV) allows concomitant between processes of the same product or between a variety of different materials, so that this news has direct evidence in the outline and season of the goods, the continuous correction of the processes, the strategic sketch, the green marketing , as well as in the public policy season. Life cycle analysis The ISO in the 90s standardized a systematized obligation organization to imply energy cycle graphology, resulting in the ISO 14040, 14041, 14042 and 14043 standards. Later in 2006, after the rigorous technical reviews these standards were merged into ISO 14040 and 14044 standards.

The environmental impact of a product begins with the extraction of raw materials and ends when the useful life of the product ends, turning it into a waste that must be properly managed. During manufacturing, companies must assess the environmental impact that these products generate during Its process, on the companies, is the responsibility of the impact caused by the parties involved in the process until the product reaches the consumer.

ACV. The international organization for ISO standardization, is an organization that has developed a series of standards focused on environmental administration or management, these standards include the ISO 14040 and 14044 series, on Life Cycle Analysis, which are voluntary.

The analysis of the life cycle will provide valuable information that will allow entrepreneurs to make decisions aimed at caring for the environment, thus promoting the environmental performance of products or services, it will also have comparative and competitive advantages by providing all the elements of analysis. to companies that want to certify their products.
