As scientific and observational evidence on global warming piles up every day, questions of economic policy in this central environmental topic have taken center stage. But as author and prominent ...Yale economist William Nordhaus observes, the issues involved in understanding global warming and slowing its harmful effects are complex and cross disciplinary boundaries. For example, ecologists see global warming as a threat to ecosystems, utilities as a debit to their balance sheets, and farmers as a hazard to their livelihoods.
In this important work, William Nordhaus integrates the entire spectrum of economic and scientific research to weigh the costs of reducing emissions against the benefits of reducing the long-run damages from global warming. The book offers one of the most extensive analyses of the economic and environmental dynamics of greenhouse-gas emissions and climate change and provides the tools to evaluate alternative approaches to slowing global warming. The author emphasizes the need to establish effective mechanisms, such as carbon taxes, to harness markets and harmonize the efforts of different countries. This book not only will shape discussion of one the world's most pressing problems but will provide the rationales and methods for achieving widespread agreement on our next best move in alleviating global warming.
Driven by the impact of economic growth, urbanization, and national strategies for low-carbon development, the TNGC of urban households in China is growing rapidly. In this paper, the feasible ...generalized least square method is used to investigate the consumption of natural gas and the per capita natural gas consumption of urban residents in 30 provinces in China (not including central heating and the natural gas consumption of natural gas vehicles). We study the factors influencing natural gas consumption by urban residents in China and conduct scenario forecasting. The empirical results show that the impact coefficients of PNGs and household income on average natural gas consumption are − 0.895 and 0.222, respectively, while the impact coefficients of the NGP are − 0.603 and 0.346, respectively. The scenario forecast results show that the consumption of natural gas in Chinese households reached 75.469 billion cubic meters in 2025. China's natural gas season peak pressure will continue to increase. In response to this, the following three suggestions are proposed. (1) According to the price elasticity of natural gas, the Chinese government should adjust and improve the mechanism for the formation of PNGs for residents and promote the marketization of natural gas. (2) Accelerate the construction of natural gas reserves and allocate the natural gas supply according to regional differences in natural gas consumption to enhance China's natural gas peak shaving capacity. (3) Improve and optimize natural gas development plans to achieve coordinated development of natural gas supply and demand.
•We analyze the factors influencing changes in the average consumption of natural gas in households.•We analyze the factors influencing changes in the residential population who use natural gas.•The price and income will affect both the number of natural gas and the average household consumption.•We have found that China's natural gas season peaking pressure will continue to increase.
Renewables are steadily growing becoming a significant part of the global energy mix, in particular in the power sector. An attractive solution could be represented by Power to Gas (PtG), an energy ...storage strategy. In the PtG process renewable or excess electric energy is used for water electrolysis to produce hydrogen that is then combined with CO2 and converted into methane (synthetic or substitute natural gas, SNG) through the Sabatier reaction. SNG is particularly interesting because leads to an easily transportable (in the existing infrastructures) fuel with a wide proven market for power, thermal and mobility final use applications. The key issue consist on putting together green hydrogen produced by electrolysis fed by renewables with high content CO2 gases supplied from different sources (e.g. syngas from gasification, biogas, geothermic fields, soil gas and gas wells). In this work the CO2 hydrogenation process, coupled with renewables, has been study in a modular, moveable, skidable plant, in the scale of 0.2–1 Nm3/h of produced SNG. The pilot plant is equipped with a methanation unit constituted by a multi-tubular fixed bed reactor able to work in cooled or adiabatic conditions; water produced is separated by a plate&shell condenser. Several sensors, an online gas analysis system and a data acquisition system allow monitoring continuous experimental tests. The methanation facility is able to work in the range of 1–5 bars. The paper reports the results of first experimental activities related to SNG production with Ru based supported catalyst. The experimental activity was carried out in order to check the operability of all components and to improve the knowledge on methanation process in different conditions relevant to Power-to-Gas applications. Different weighted hourly space velocity (WHSV), gas inlet composition, reagent mixture, H2/CO2 ratio, temperature and pressure conditions have been investigated. Increasing pressure drives CH4 production as CO2 conversion is kinetically boosted by raising pressure. Results show that a decreasing trend of XCO2 is observed by increasing WHSV. Results indicate high CO2 per pass conversion with CO2/H2 concentrate feed using Ru based catalyst. Finally the effect of CH4 in the feed was studied emulating two reactors in series. Biogas representative CO2/H2/CH4 mixtures were tested in order to study direct methanation as a biogas upgrading technology.
For many years, the trend of increasing energy demand has been visible. Despite the search for alternative energy sources, it is estimated that oil and natural gas will be the main source of energy ...in transport for the next several dozen years. However, the reserves of renewable raw materials are limited in volume. Along with the degree of depletion, oil recovery becomes more and more difficult, even though the deposits are not yet completely empty. Therefore, it is essential to find new methods to increase oil and gas recovery. Actions aimed at intensifying oil recovery are very rational use of energy that has not yet been fully used. Usually, an increase in oil recovery can be achieved by using extraction intensification methods. However, measures to increase oil recovery can be implemented and carried out at any stage of the borehole implementation. Starting from the well design stage, through drilling and ending with the exploitation of oil and gas. Therefore, in order to further disseminate technologies and methods related to increasing oil recovery, a special edition has been developed, entitled "Fundamentals of Enhanced Oil Recovery". This Special Issue mainly covers original research and studies on the above-mentioned topics, including, but not limited to, improving the efficiency of oil recovery, improving the correct selection of drilling fluids, secondary methods of intensifying production and appropriate energy management in the oil industry.
This paper reports on an investigation into the transient compressible flow physics that impacts transmission system operation under variable gas quality conditions. Gas quality issues are becoming ...more prominent due to the diversification of supplies, e.g. new LNG terminals, unconventional gas sources and decentralized green fuel injections (hydrogen, substitute natural gas). A comprehensive pipeline flow model with gas composition tracking resulting from the coupling of mass and chemical energy transport models has been developed to study the effect of the variation in gas composition on the operation strategy of the pipeline system. Three illustrative examples demonstrate the effectiveness of the proposed approach. The first two examples present model validation on a field data concerning variable gas quality and variable demand conditions in the gas transmission system. The impact of hydrogen injection to the pipeline system on gas properties and flow characteristics is illustrated by the third example involving analysis of short-term scheduling with gas quality control. The results show that variable gas quality has a significant influence on the pipeline system inventory and peak capacity as the gas mixture compounds change and energy wave is introduced to the pipeline system.
•Transient thermo-hydraulic model for pipeline transportation of natural gas under variable gas quality conditions is proposed.•Chemical energy flow rate instead of volumetric flow rate is selected as a dependent variable.•Model validation on field data is carried out.•Operating strategy of the pipeline system with energy flow rate as a control variable is simulated.•Advantages of energy-based over volume-based approach are illustrated.
