Since both are generated in a single process, it is necessary to allocate the emissions to by-products for comparing their environmental performance. Numerous methods exist resulting in very different allocations. There is no consensus regarding the method choice. The main objective of this article is the development and implementation of an evaluation scheme allowing the choice of an appropriate method for specific applications. This scheme consists of nine criteria in the categories “Applicability”, “Environmental relevance”, and “Systematic approach” allowing a rating. The Finnish method performs best for a standard use case resulting in emission factors of 322 g CO₂ / kWh_el and 192 g CO₂ / kWh_th. Both are associated with less emissions per unit then the electricity and district heating mix of Germany in 2020 that were 375 g CO₂ / kWh_el and 270 g CO₂ / kWh_th. Therefore, cogeneration electricity and heat could contribute to climate protection in the short- to mid-term. The implementation of two sensitivity analyses shows that the location and country-specific emission factors can have a great influence on the results and the contribution to climate protection. Depending on use case and individual importance of certain criteria the Energy, the Exergy or the Greenhouse Gas method can be preferable. Each scored with one point less than the Finnish method. In contrast to existing publications, this study supports decision-makers in transparently selecting an appropriate allocation method when assessing the products of cogeneration by considering different criteria.</p></div>","PeriodicalId":101071,"journal":{"name":"Renewable and Sustainable Energy Transition","volume":"4 ","pages":"Article 100069"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50195065","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 study assesses the trajectory of the Greek electricity mix and its reliance on natural gas under the current policy framework on the one hand, and an ambitious scenario aiming for complete decarbonisation by 2035 on the other. We model these scenarios using an energy system modelling framework, comprising LEAP and OSeMOSYS model implementations for Greece, and use a stakeholder-informed fuzzy cognitive mapping exercise to uncover transition uncertainties. While power generation from natural gas is projected to increase by almost 50% until 2030 under existing policies, the proposed decarbonisation scenario has the potential to achieve complete independence from Russian gas by 2026 while also leading to a cleaner and considerably cheaper power sector. This ‘higher climate ambition’ scenario is found feasible and more robust in case high fossil fuel prices persist post-2022, even if bottlenecks stressed by stakeholders such as community acceptance or technological constraints emerge and potentially constrain the expansion of certain renewable energy technologies.

Key function of the model is an in-depth cost analysis by a breakdown of costs among types of measures (home equipment, insulation, local equipment and infrastructure), cost components (investments, O&amp;M, taxes, subsidies) and stakeholders (system, government, owner-occupiers, renters, real estate owners, grid operators and local entrepreneurs).

As a major emitting, high-income, developing economy that is largely dependant on hydrocarbons, Russia currently sits in the middle of the two groups, needing not only to drastically reduce emissions but also to ensure necessary economic growth to finance decarbonisation. This study explores two mitigation scenarios, one reflecting a cautious and the other a more ambitious decarbonisation pathway for Russia. These scenarios are co-created with a group of 135 national stakeholders, who inform the underlying assumptions based on their perceptions, expectations, and reservations: the more conservative scenario reflects the average of all input, while the ambitious scenario represents the optimistic end of the stakeholder input range. The two scenarios are modelled in CONTO, an input-output system of interconnected macro-structural calculations at the national level, to analyse the interplay between Russia's economy and decarbonisation progress, shedding light on the implications of mitigation for socioeconomic development. We find that, even for a country as dependant on hydrocarbons and under the most ambitious pathway that is still within experts’ realistic reach, Russia can achieve drastic reduction in absolute emissions and reach net-zero closely after 2050, while also achieving positive economic development in the long run. We highlight the need to prioritise a diverse set of mitigation options currently available and relevant to the Russian context, including energy efficiency and intensity improvements, electrification, and nuclear power, as well as to exploit the large potential lying within the Russian ecosystem's carbon sinks.</p></div>","PeriodicalId":101071,"journal":{"name":"Renewable and Sustainable Energy Transition","volume":"4 ","pages":"Article 100055"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50195043","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}

However, analyses show that on its own, the IRA is insufficient to meet the nation's stated climate goals. We use an energy system optimization model to understand how the U.S. can build on the IRA to meet climate goals. We model two carbon taxes and a suite of efficiency, fuel, and technology standards, including a clean electricity standard (CES), electrification standards for commercial and residential buildings, a zero-emission vehicle (ZEV) standard, and a clean fuel standard for industry. We compare these three policy scenarios to the U.S.’s stated climate goals (Nationally Determined Contribution). The two carbon taxes and the suite of standards achieve the GHG emissions goals outlined in the Paris Agreement, but no scenario reaches net-zero GHG emissions by 2050. Notably, we find that the average GHG abatement cost under the modeled standards is comparable to a carbon tax set at ∼$200/ton, and both policies achieve similar emissions reductions. Temoa's cost-minimization structure results in the carbon tax always reducing emissions more cheaply than a set of standards; but the similarity in cost emphasizes the near-optimal second-best nature of well-designed standards.” The marginal cost of GHG emissions reduction in each scenario is less than 2% of total system costs. While the modeling results indicate that meeting climate targets may still be possible, they demonstrate that doing so will require rapid and sustained deployment of zero-emission technologies across the energy system.</p></div>","PeriodicalId":101071,"journal":{"name":"Renewable and Sustainable Energy Transition","volume":"4 ","pages":"Article 100065"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50195062","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}

Our power plant stock accounting model results show that achieving zero emissions from the power sector by the mid-century requires either an ambitious expansion of renewables backed by gas-fired generation equipped with carbon capture and storage or a significant increase of nuclear power. The first strategy implies replicating and maintaining for decades the maximum growth rates of solar power achieved in leading countries and becoming an early and ambitious adopter of the carbon capture and storage technology. The alternative expansion of nuclear power has historical precedents in Korea and other countries but may not be acceptable in the current political and regulatory environment.

The inherent variability of solar resources makes it challenging to integrate large amounts of solar energy into the electric grid. However, the weather factors that influence solar production are often local in nature. In this study, eleven solar photovoltaic systems with publicly available historical data were identified for analysis. The systems are located within a circle with a diameter of approximately 130 km. The historical power output data for each system were acquired, and quality control measures were applied. A comparison is made between the variability of the time-varying power output from individual systems compared to the variability of the aggregated output of the eleven systems combined. Next, the effect of increasing the geographical spread of the aggregated systems is investigated. This is done by comparing the variability of the aggregated time-varying power output from closely-spaced systems against the variability of the aggregated time-varying power output from systems spread out over a large geographical area. Next, the correlations between the outputs from each of the individual systems are explored. The data show that the correlation decreases by approximately 0.1 for each 80 km of separation distance. Finally, the historical solar output data is used to define the “expected output”, and the deviation from this expected output is compared for individual systems and various sets of aggregated systems. The four aggregated systems located far apart are 31% more likely to have a combined output that is close to their expected output, defined as having a normalized power output deviation less than or equal to 0.2 kW/kW. Furthermore, the four aggregated systems located far apart are 54% less likely to have a combined output that is significantly different from their expected output, defined as having a normalized power output deviation greater than or equal to 0.4 kW/kW.</p></div>","PeriodicalId":101071,"journal":{"name":"Renewable and Sustainable Energy Transition","volume":"3 ","pages":"Article 100052"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50199281","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}
