“…As shown in Table 12, the results in this study were different from previous international findings [16,33,34] because the GHG emissions level of the grid in the studied project is low due to the large contribution of hydro power. However, if the project can supply electricity to other regions in China, the GHG emissions reduction effect is expected to be similar to that shown in other countries.…”

Abstract:In this paper, we used the life-cycle analysis (LCA) method to evaluate the energy consumption and greenhouse gas (GHG) emissions of natural gas (NG) distributed generation (DG) projects in China. We took the China Resources Snow Breweries (CRSB) NG DG project in Sichuan province of China as a base scenario and compared its life cycle energy consumption and GHG emissions performance against five further scenarios. We found the CRSB DG project (all energy input is NG) can reduce GHG emissions by 22%, but increase energy consumption by 12% relative to the scenario, using coal combined with grid electricity as an energy input. The LCA also indicated that the CRSB project can save 24% of energy and reduce GHG emissions by 48% relative to the all-coal scenario. The studied NG-based DG project presents major GHG emissions reduction advantages over the traditional centralized energy system. Moreover, this reduction of energy consumption and GHG emissions can be expanded if the extra electricity from the DG project can be supplied to the public grid. The action of combining renewable energy into the NG DG system can also strengthen the dual merit of energy conservation and GHG emissions reduction. The marginal CO 2 abatement cost of the studied project is about 51 USD/ton CO 2 equivalent, which is relatively low. Policymakers are recommended to support NG DG technology development and application in China and globally to boost NG utilization and control GHG emissions.

“…The electricity generation inventory was carried out and the emissions were also calculated according to emission factors AP-42 for natural gas combustion (EPA 2009). The process information was supplied by the combined cycle power plant El Encino (Chihuahua Mexico), which operates using natural gas combustion and has less environmental impacts compared to coal combustion systems (Agrawal et al 2014).…”

This research studies the application of a life cycle assessment (LCA) methodology to evaluate the environmental impacts of an improvement to traditional brick manufacture. This study case was carried out using realistic combustion gas measurements and experimental results. The traditional process and the addition of one or two hopper blower (HB) devices provided the three scenarios for this study, which were evaluated quantitatively using a set of metric indicators for potential impacts while applying a "cradle-to-gate" approach. A decreasing trend was observed for most values of the potential impact categories when the device was used. An opportunity to improve the traditional process by adding this device has been identified, as a reduction in the environmental impact categories has been observed. The study suggests that the LCA tool may be valuable for quantifying the environmental impacts of improvements in the processes.

“…Since the advent of the industrial age, human activities (including agriculture) contributed to the enhanced production of greenhouse gasses. Reasons for emissions of these GHGs can be multi-fold; however, combustion of coal [8]; oil products [4]; and natural gas combustion [1], oil and natural gas extraction/ refining/processing [1,33]; transport by road, rail [32]; electricity generation [53]; biomass burning [2]; industrial sectors such as cement manufacturing units [57]; bricks manufacturing [3]; from agriculture sector [19] etc. are the major ones.…”
