Limiting climate change requires internalizing that economic externality. Trading GHG emissions is a possible solution, yet the trading implemented to date is based on the issuance of permits, which are licenses to emit, meaning net-positive emissions. To attain net-zero, positive emissions must be traded against negative emissions. Modeling an economy in which GHG credits are earned for removing emissions reveals a GHG-Sector through which economic activity limits climate change. Analysis of the model indicates that if direct air capture of CO2 is part of attaining net-zero, then market prices will direct all pre-emission captured CO2 (e.g., flu gas) to sequestration. The policy implications of a GHG-Sector for sustainable transitions in aviation, food production, and elsewhere are discussed.","PeriodicalId":234456,"journal":{"name":"Politics & Energy eJournal","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132244984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The Green Transition in Oil Dependent Economies in the MENA Region 'Turning off the Pumps, Breaking the Oil Addiction, and Greening the Desert' Case Study: A Non-Oil Future for Saudi Arabia and Algeria?","authors":"A. Gaillard","doi":"10.2139/ssrn.3877500","DOIUrl":"https://doi.org/10.2139/ssrn.3877500","url":null,"abstract":"The Curious Case of the Green Transition: Managing a Historic Shift in Oil Exporting Countries While the Middle East and North African (MENA) region is home to only 6% of the world’s population, it controls 60% of the world’s known oil resources and almost half of the world’s natural gas reserves (Hilmi et al. 30). An additional source strengthens this statement exhibiting that total production of oil in MENA countries accounts for 34,418 thousands barrels per day while that of natural gas amounts to 798.3 billion cubic metres per year (Exhibit 3). Due to scientific consensus on anthropogenic climate change, oil is considered a controversial energy source and therefore deserves special attention. Trends towards non-carbon based and sustainable energy sources are gaining momentum worldwide. Meanwhile, trends towards clean energies are gaining momentum worldwide. Given its large number of oil-dependent countries, this will have profound ramifications for the MENA region. Although the classification of strong and weak green performers has been a contentious process, these data are nonetheless the most reliable sources available to date. Under this classification, Saudi Arabia ranks fourth and is considered a modest performer. Algeria, ranked fifth, is considered a slightly weaker performer (Tagliapietra, 2017, 20). Saudi Arabia is presumed to be in the top group of oil exporters, meaning that oil revenues account for 40% of GDP. Algeria ranks in the second tier, which consists of countries whose oil revenues range from 20 to 40% of their GDP (Tagliapietra, 2017 16). If taken as a common denominator, ‘green energy’ is analytically useful in comparing Saudi Arabia and Algeria as they embark on the path to non-carbon energy solutions. There are several foundational, yet still unanswered, questions about energy sector transformations in petroleum exporting countries. First, why would MENA countries transition to green energy before they exhaust their petroleum reserves? Second, when will commercially viable oil reserves be depleted? Lastly, what are the tradeoffs between economic development and a Green Transition? As Eckart Woertz, the Director of the GIGA Institute for Middle East Studies in Hamburg, argues, the use of clean energy is still limited in the region, particularly compared to Europe (Cochrane). If this is the case, then what incentive structures are likely to influence decision making in this domain? While a complete analysis of these questions is beyond the scope of this paper, establishing a basic understanding of both supply-and demand-side incentive structures serve as a foundation for rational economic and policy decisions. Certainly, reforms and programs are undertaken in MENA countries to switch to clean energy. Both Saudi Arabia and Algeria have proposed programs and reforms that incorporate sustainable objectives. Examples include Algeria’s National Strategy for the Fight Against Poverty (2005–2015) and Five-Year Plan (2010–2014) ","PeriodicalId":234456,"journal":{"name":"Politics & Energy eJournal","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129718408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gurule","doi":"10.2139/ssrn.3825873","DOIUrl":"https://doi.org/10.2139/ssrn.3825873","url":null,"abstract":"In rejoining the Paris Agreement, the United States should be working to limit global temperature increases as a result of climate change caused by atmospheric greenhouse gas emissions to 1.5 degrees Celsius above pre-industrial temperatures. We are not currently on track to achieve this goal, requiring further consideration of the ways we regulate greenhouse gas emitting activities. Among other regulatory tools, the United States regulates greenhouse gas emitting activities through tax. The utility of regulating through tax in the context of climate change is two-fold. First, as others have noted, tax is particularly well-suited to make GHG emitting activities comparatively more expensive in a way that can force taxpayers to bear externalized social costs of GHG emitting activities resulting in climate change. Second, tax is able to address climate change as a problem that will disproportionately impact low-income and marginalized groups. The tax code does not currently adequately fulfill either of these regulatory purposes. In part, this may be because of the view shared by many that there is a conflict between regulating to limit GHG emissions through a carbon tax and regulating to advance progressive policy. This article uses the non-refundable credit for carbon capture, utilization and sequestration in section 45Q of the Internal Revenue Code and an implicit regressive carbon tax on the public created by failing to curb climate change to advocate for an end to arguments pitting a carbon tax or improved Pigouvian subsidies (such as a revised section 45Q as discussed herein) against progressive goals. It’s time to move past a perpetuation of current policy—which is a poor tool for curbing GHG emissions and which is entrenching regressive results of climate change--and to try implementing policy that is intentionally designed to both actualize green goals and progressive results.","PeriodicalId":234456,"journal":{"name":"Politics & Energy eJournal","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124157675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study focused on modelling the generated electricity during the “before and after” outage of a typical unit, in one of the Eskom Benson’s thermal coal power plants rated at 600 MW and mechanical conversion efficiency of 35%. The dataset for the chosen input parameters are collected from the metering cards and the generated electrical power are obtained from the installed power meters to the designated unit in the power plant. Multiple linear regression models (MLR) and Artificial Neural Networks (ANN) for both the “before and after outage” power generated are developed, tested and validated with the input parameters as the average air heater temperature, average main stream super-heater temperature, average high pressure heater’s temperature, the total mass of coal burnt, average of the condenser well pressure and temperature and the auxiliary power consumed. The MLR models and the ANNs for both the “before and after” outage power generated gave excellent correlation coefficients of over 0.950. Furthermore, it can be concluded that the ANNs gave better predictions over the counterparts MLRs model based on the correlation coefficients and the mean square errors derived from the models.","PeriodicalId":234456,"journal":{"name":"Politics & Energy eJournal","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131866016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to improve the existing technologies for the development of natural gas fields in the conditions of the manifestation of a water-driven mode of development of productive reservoirs, a study was carried out using the main tools of hydrodynamic modeling Eclipse and Petrel from Schlumberger (USA). On the basis of a three-dimensional digital model of gas condensate, the influence of the density of injection wells on the coefficient of natural gas extraction during the injection of carbon dioxide into productive reservoirs on the verge of a gas-water contact was investigated. The study was carried out for a different number of injection wells (4, 6, 8, 12, 16 wells), which are evenly spaced along the perimeter of the initial gas-water contact. According to the results of the calculations, it was found that the production of formation water decreases with an increase in the density of the well grid. In the case of using 4 wells to inject carbon dioxide into a productive reservoir, the accumulated production of formation water at the end of development amounted to 169.71 thousand m3. With an increase in the number of injection wells to 16 units, the accumulated production of produced water decreased to 0.066 m3. This result is achieved due to a more complete coverage of the perimeter of gas content with carbon dioxide and the creation of an artificial barrier between water and natural gas, which leads to a more effective blocking of the movement of produced water into productive reservoirs. According to the results of statistical processing of the calculated data, the optimal value of the number of injection wells was determined when injecting carbon dioxide into the reservoir. The optimal value of the number of injection wells at the time of the breakthrough of carbon dioxide into the first production well is 7.86 (8) wells. The maximum value of the number of injection wells according to the results of statistical processing is 6.8 (7) wells. The final gas recovery ratio for the given optimal injection value is 61.88 %. On the basis of the calculations, the technological efficiency of using as an agent for injecting carbon dioxide at the boundary of the gas-water contact was established in order to prevent selective watering of productive reservoirs and production wells.","PeriodicalId":234456,"journal":{"name":"Politics & Energy eJournal","volume":"14 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126046697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The limited impact of the Kyoto Protocol on curbing emissions, and the gap between the ambitions of its successor and the Paris Agreement's lack of sanctioning mechanisms for addressing noncompliance, demonstrates both the difficulties in negotiating ambitious environmental agreements and the reluctance of countries to comply with their agreed emission targets once they have joined the treaty. Therefore, a better understanding of the obstacles and opportunities that the interactions between domestic and international policy pose for the design of successful international climate cooperation is of utmost importance.

However, impact of such efforts are diluted if there is not sufficient uniformity: Different blockchains idiosyncratically quantifying carbon credits and reporting them based on standards not widely adopted may offer only some improvement over the status quo. In this paper, we specify a top-level architecture that uses Semantic Web ontologies to complement a blockchain-based MRV system to address the need for uniformity and sharability. We pose this within the context of the real-life Reciclo Orgánicos project, an international collaboration to reduce GHG emissions from Chile’s municipal waste sector. Our design conceptualizes transforming “smart standards” that are efficiently designed and harmonized using IT into ontologies of quantification methodologies and verification standards, which in turn can be used develop smart contracts executable on, and interoperable between, different blockchain platforms.

The answer to this question determines many economic consequences of climate policies, i.e. in terms of costs for downstream industries. It requires, however, to first identify the cost impact of carbon pricing on the price-setting entity on the power market. Economic theory tells us that power prices are determined by the cost of the marginal plant. We propose two simple approaches to conclude on marginal technologies in electricity wholesale from public data. Both approaches are complementary, easy to implement, and based upon assumptions which are commonly used in more complex energy system models. We exemplify their use with a policy example on the compensation for indirect emission costs from the EU Emissions Trading Scheme. We find that the current policy design severely overweighs CO 2 emissions from lignite power plants in the Central Western European power market, which may lead to overcompensation of industrial power users and therefore to a distortion with regard to the policy’s stated goal.","PeriodicalId":234456,"journal":{"name":"Politics & Energy eJournal","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124386672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This model was implemented in the study on an example of a method of acoustic leakage detection, which uses the inter-correlation function. A block diagram of an acoustic system for detecting leakage location, its main blocks, and their parameters were presented. To test the working capacity of the mathematical model, a computer measuring experiment was conducted in the MATLAB software system.
