The result shows the All Natural Gas project saves 8% energy and reduces 38% GHG emission compared with tradition project using coal and grid electricity
we used Life Cycle Analysis (LCA) method to evaluate the energy consumption and GHG emission of Distributed Energy System projects.
Between the Distributed Energy System and the traditional energy system, there is a difference in emissions that affects sensitivity factors such as HPR (heat-power ratio

ARTICLE - LIFE CYCLE ANALYSIS

The article Life Cycle Analysis of Distributed Energy System Projects Energy Consumption and GHG Emission - A Case of Beer Brewery Auxiliary Power Supply in China, promotes projects to provide energy from clean energy.

The Life Cycle Analysis (LCA) method is used to assess the energy consumption and GHG emissions of projects in the Distributed Energy system and thus compare their energy consumption and emissions performance, it also allows analyzing projects Based on renewable energy, future research can be done with the results obtained. Life cycle analysis allows the development of evaluation methods.

The result of the All Natural Gas project shows that it saves 8% energy and reduces 38% GHG emissions compared to projects that use coal and electricity from the network, thus contributing to the environment.

The NTC ISO 14040 and 14044 standards are determined to do the life cycle analysis in terms of environmental assessment through requirements, guidelines, principles and reference framework to improve performance.

NTC ISO 14040: This standard deals with an environmental assessment methodology that allows analyzing and quantifying the environmental aspects and impacts of a product or service throughout its life cycle.

NTC ISO 14044 This standard is used to evaluate the life cycle of products, generating the requirements and guidelines to carry out the evaluation, which includes:

• The definition of the objective

• What is the scope of the life cycle?

• Analyze life cycle inventory
The life cycle analysis of a product includes the activities of extraction and acquisition of raw material, production, use, recycling and finally final disposal.

At a global level, the importance of preserving the environment has increased, and taking into account the impacts associated with products, both at the level of manufactures and the level of consumption, which is why through techniques developed for the analysis of the life (LCA) help to identify the improvement of environmental performance of products in the different processes of their life cycle, in the improvement of decision-making through strategic planning, design and redesign of processes, the implementation of effective indicators of environmental performance , including measurement techniques for environmental aspects and potential environmental impacts such as the use of natural resources and the consequences of emissions and discharges during the life cycle of a product, starting from the origin such as the acquisition of raw material until its final destination use.

In Sichuan province, China, the first Distributed Energy System project is being carried out to provide electricity to that country's network. The article examines the energy and environmental properties of the China Resources Snow Breweries Distributed Energy System project, becoming the first to evaluate a unique project and provide policy guidance to advance major projects like that.
Becoming vitally supportive of the political decision to move forward in Distributed Energy System projects and move forward. According to a leading energy expert group (ICIS), 46 natural gas-based distributed energy system projects have been built in China, with another 16 projects expected to be built in 2016.

The article Life Cycle Analysis of Distributed Energy System Projects Energy Consumption and GHG Emission - A Case of Beer Brewery Auxiliary Power Supply in China, promotes projects to provide energy from clean energy.

We analyze that the natural project saves and reduces resources that are harmful and pollute the environment, But we cannot say the same about the traditional project that exploits coal in its resource, which does generate pollution. So they expanded the feature, which in turn seeks to mitigate the damage, since they do not have to waste the use of energy as a natural factor.

Little summary

China is advancing by leaps and bounds in the technologies of the future, developing solar and wind energy like no other country on the globe. "China takes this lead as it recognizes the enormous market potential and economic advantages," says energy economist Claudia Kemfert of the German Institute for Economic Research (DIW), which in turn advises the German government from the Advisory Council on the Environment.

The Tsinghua Life Cycle Analysis Model (TLCAM) has been used to examine primary fossil energy consumption and greenhouse gas (GHG) emissions for alternative vehicle fuels in natural gas (NG) in China. The results indicated that (1) compressed and liquid CNG vehicles have similar uses of fossil-wheel-well (WTW) fossil fuels as electric vehicles powered by gasoline and diesel.

heating plants and cogeneration plants. The UT-L heating boiler is offers as a fully assembled unit, comprising the boiler body, the burner, heat exchanger heat and regulation technique and security, which is already wired with the terminal box. The integrated combustion fireplace ends in an inverted chamber completely surrounded by water, which flows into the first smoke passage. Both the first and second steps of fumes do not contain elements integrated circulation. The functional round design provides optimum resistance to pressure. Fireplace, water volume, radiation and convection heating surfaces are optimally dimensioned and harmonized with each other.

Wind and photovoltaic generation sources increased by 14 and 17.3 percent year-on-year respectively, while hydroelectric plants experienced a 1.1 percent increase. Thus, biomass power generation experienced the fastest growth with a capacity that expanded 26.6 percent to stand at 22.54 million kilowatts.

In 2019, China generated 2.04 trillion kilowatt hours of electricity using renewable energy sources, accounting for 27.9 percent of total generation, an increase of 1.2 percentage points year-on-year.

During the past year, the country also has a high efficiency in the use of renewable energy. The hydroelectricity utilization rate reached 96 percent, an increase of 4 percentage points, while the average reduction rates of wind and photovoltaic energy decreased by 3 percentage points and 1 percentage point, respectively.
