Deployment of new onshore wind power faces challenges due to growing resistance, prompting increased interest in the development of effective deployment strategies. One approach is to examine historical deployment to identify factors shaping its distribution within a country. Current literature presents inconsistent results and lacks theoretically grounded approaches. This study enhanced the methodology for analyzing subnational wind deployment in two ways. First, techno-economic, socio-technical, and political perspectives from national energy transition literature were employed to identify relevant deployment mechanisms. Second, the approach differentiated between small-scale and large-scale wind power to avoid conflating results from obsolete technologies. The method is piloted in Sweden where wind deployment varied significantly despite nationwide policies. Findings from Sweden suggest that subnational heterogeneity of wind deployment at the municipality level is not primarily determined by techno-economic factors, but also by socio-technical and political variables. Deployment mechanisms also evolved over time, possibly due to technological upscaling. Small-scale wind power (≤1.5 MW) leveraged agricultural land and accumulated local experience, while large-scale wind power (>1.5 MW) is correlated with political variables such as siting policy and voter turnout. Municipalities with the highest large-scale deployment typically have extensive forest cover, low population density and wind speeds within a lower median range relative to the national median. Findings from Sweden can inform hypotheses for evaluation in other countries and future research can extend the proposed analytical framework to different national contexts.

Malaysia aims to achieve carbon neutrality by 2050, addressing climate change by transitioning to low-carbon electricity. With the power sector contributing 36 % of carbon emissions in 2019, solar photovoltaic (PV) is a key solution, given Malaysia's abundant sunshine. While government roadmaps emphasize solar PV, the retrofit market remains underexplored. This study investigates barriers to rooftop solar PV adoption in existing houses using the unified theory of acceptance and use of technology (UTAUT2), examining economic, environmental, social, technological, and regulatory factors. Combining quantitative surveys and in-depth interviews, it identifies drivers and obstacles, providing actionable insights for policymakers and stakeholders to accelerate adoption and support Malaysia's decarbonization goals. Findings from SEM indicate that Performance Expectancy (PE, β = 0.311, p < 0.001), Price Value (PV, β = 0.245, p = 0.006), Facilitating Conditions (FC, β = 0.311, p < 0.001) and Environmental Concern (EC, β = 0.253, p < 0.001) significantly predict Behavioral Intention (BI) to adopt rooftop solar PV systems. Social Influence (SI, β = −0.111, p = 0.165), Effort Expectancy (EE, β = −0.098, p = 0.266) and Hedonic Motivation (HM, β = 0.082, p = 0.167) were statistically insignificant. The model explained 88.6 % of the variance (R² = 0.886), with high sampling adequacy (KMO = 0.949). However, qualitative findings reveal that Social Influence plays a significant role in shaping BI, highlighting the importance of peer recommendations and community perceptions. These integrated findings highlight the importance of considering economic, social, and environmental factors in the adoption process. This study expands the applicability of UTAUT2 to new technology research, particularly for rooftop solar PV, providing valuable insights for policymakers and stakeholders to promote solar PV adoption and support Malaysia's decarbonization goals.

The worldwide matter of climate change, which has negative impacts on the Earth and its inhabitants, is attributed to the elevation in emissions of greenhouse gases (GHGs) caused by the burning of fossil fuels. Due to the disproportionate rise of GHGs in recent decades, global warming and climate change have necessitated the adoption of suitable measures. In this context, the Paris Agreement, which seeks to diminish global GHG emissions, was ratified in 2015 by the UNFCCC to impede the rise in temperature. As a signatory to the contract, Iran has pledged to lower its GHG emissions by 2030, as outlined in the country's intended nationally determined contributions (INDC). The power sector stands out as the primary source of these gas emissions; thus, the article focuses solely on this issue. To fulfill Iran's obligations under the Paris Agreement regarding the power industry, three scenarios were developed using the EnergyPLAN model, i.e., Business as Usual (BAU), National Strategic Plan on Climate Change (NSP), and Integrated Renewables and Efficiency Enhancement (IREE). Unlike the other two scenarios, the BAU scenario fails to meet Iranian obligations. Iran appears to have the capacity to honor its commitments by the NSP framework before 2030, yet its feasibility remains uncertain. Consequently, the IREE scenario is recommended, which could comply with Iran's commitments under the Paris Agreement by increasing the capacity of renewable energies to 3200 MW (wind and solar) and enhancing the average efficiency of thermal power plants to 41 %.

Coal regions are particularly vulnerable to the plans to reduce regional pollution and move towards a climate-neutral economy. The European Union therefore supports the transition away from coal in those regions that are socio-economically most affected to reduce negative impacts for communities. Coal regions have developed their Territorial Just Transition Plans (TJTPs); however, it is unclear which impacts the plans should address to ensure a just transition and to what degree. To address this gap, the following research aims to develop an indicator and impact matrix to assess the extent to which TJTPs address key impacts related to just transitions and how are these quantified. Key just transition impacts were investigated quantitatively and qualitatively in six coal regions. The results indicate that the expected transition impacts on communities in coal regions are mainly negative. Furthermore, it was also found that TJTPs predominantly address the impacts on employment and the environment, whereas social and demographic impacts are less comprehensively considered. These deficiencies should be addressed in each region in order to define tailored policies and investments that can assist in minimising negative impacts and capitalising on positive benefits for communities. The proposed approach can facilitate a more precise definition and assessment of regional impacts of transition towards climate neutrality, thereby aiding the identification of policy areas and measures that will enable the implementation of a truly just transition.

Propylene, a fundamental chemical, has witnessed a significant surge in demand in recent decades, establishing itself as the second most primary intermediate compound after ethylene. Propylene manufacturing currently depends on non-renewable resources, specifically naphtha or propane from fossil sources. The conventional methods are economically feasible and mature; however, they emit greenhouse gases and consume non-renewable resources. Therefore, it is necessary to transition to more sustainable production methods. This review aims to provide and analyze many possible routes for the production of propylene using sustainable resources. The categorization of these pathways is determined by the raw material employed for the manufacture of propylene. Out of the several paths considered, bio-propane dehydrogenation stands out as a viable option for producing propylene in the future. Furthermore, this study examines and reports on the analysis of catalyst selection, the design of operating conditions, and the yield and selectivity of propylene in each pathway. Zeolite-based catalysts, particularly ZSM-5, exhibit remarkable selectivity in propylene synthesis across several processes. To fully comprehend the sustainability and feasibility of these paths, this research also reviews environmental impact and techno-economic metrics of several established propylene production methods.

The unreliable power supply, high cost of electricity and non-payment of electricity bills among the state-owned hospitals in Ghana badly affects health services delivery. Meanwhile, hospitals can obtain reliable electricity and reduce their bills using rooftop solar PV systems technology, yet little attention has been given to this in Ghana. This study aims to technically and economically assess the feasibility and viability of implementing rooftop solar PV electricity under the net metering programme that Ghana recently adopted for hospitals. The study uses a case study (Sunyani Teaching Hospital) through empirical technical assessment (Google Earth Pro software, load profiles and grid connection option) and engineering econometrics (Net present value - NPV, Internal rate of return - IRR, Discounted payback period - DPP and profitability index - PI) to arrive at its conclusion. The technical results show that the Sunyani Teaching Hospital has a total installed load of 297,471 kW and an annual energy demand of 1,493,326 kWh. The proposed PV plant can produce about 9,418,145 kWh of energy per year. The economic results show an NPV of GHS 64.09 million, IRR of 34 %, PI of 2.4, and DPP of 4 years for the system configuration without battery storage, while an NPV of GHS 61.21 million, IRR of 28 %, PI of 2.3, and DPP of 4 years for the system configuration with 10 % battery storage capacity. The solar PV system's resultant annual carbon dioxide savings from the study is 8,005,423.34 kg, while a 200,135,588.38 kg carbon reduction can be achieved in the project's lifetime. The economic evaluation of the proposed solar PV microgrid using carbon credit resulted in higher profitability. An NPV of GHS 72.89 million, IRR of 36 %, PI of 2.6, and DPP of 4 years were realized by considering carbon credit in the analysis of the system configuration without battery storage. At the same time, the system configuration with 10 % battery storage capacity has an NPV, IRR, PI, and DPP of GHS 70.04 million, 32 %, 2.5, and 4 years, respectively. The results show that the net present values for cases with 50 % storage, and 100 % storage are GHS 70.0 million, GHS 58.6 and GHS 44.4 million, respectively. Similarly, IRRs 32 %, 22 % and 14 % were obtained in the order of the above cases. Again, the PI obtained are 2.5, 2.0, and 1.6 in order of the above cases, and lastly, the period for the investment recovery is 4 years, 5 years, and 6 years, respectively. The results indicate that hospitals in developing countries can leverage on rooftop solar PV system to enhance their health services delivery.

Over the past few decades, there has been significant development in actions aimed at global energy transition, with the goal of reducing greenhouse gas emissions. The energy sector plays a significant role in this endeavor, contributing 76% of the world's total emissions. Considering electrification as an alternative promotes the deployment of technologies that use renewable sources, such as wind energy in coastal and offshore areas. In Colombia, wind energy alone has an accumulated technical potential of approximately 82 GW, mainly concentrated along the northeastern coast. Exploiting this technology enables the development of the national electrical system, reducing dependence on hydroelectric generation, strengthening the system against climate seasonality by ensuring supply security, environmental sustainability, and equitable energy access. Supported by system dynamics modeling, this paper presents four scenarios that explore possible futures for wind capacity deployment in Colombia between 2020 and 2050. It considers uncertainties in political and economic domains, as well as crucial national factors such as social acceptance, supply chain development, and transmission infrastructure. Favorable alignment of these factors towards wind diffusion could lead to nearly 29 GW of installed capacity by 2050, representing 40% of the projected total capacity of the electricity sector.

Combined cycle (CC) plants are expected to play an important role in balancing generation of heat and electricity from non-dispatchable renewable energy sources. In this work, we study different retrofit options for using hydrogen in CC plants to reduce the plant’s CO2 emissions. These options are: direct combustion in the gas turbine, supplementary firing in the heat recovery boiler (duct burner), and oxy-fuel combustion of hydrogen for direct steam production.
Therefore, we first simulate the performance of an exemplary CC plant in a detailed non-linear process model. Second, we fit a surrogate, mixed-integer-linear model that can optimize the plant operation within a reasonable computation time over a long time frame (one year, with hourly resolution). This surrogate model allows for an in-depth analysis of hydrogen combustion retrofits in CC plants, assessing both profitability and environmental impacts. The findings suggest that direct combustion of hydrogen in the gas turbine becomes economically viable only when hydrogen is cheaper than natural gas. Although a duct burner fired by natural gas can enhance the plant’s profitability, it also increases the specific carbon emissions. Burning hydrogen in a duct burner, however, is not cost-effective. Retrofitting the steam cycle of the plant with an oxy-fuel hydrogen burner, however, can improve both profitability and CO2 emissions of electricity and steam generation.
联合循环（CC）发电厂有望在平衡非分散可再生能源的热电生产方面发挥重要作用。在这项工作中，我们研究了在 CC 发电厂使用氢气以减少发电厂二氧化碳排放的不同改造方案。这些方案包括：在燃气轮机中直接燃烧，在热回收锅炉（管道燃烧器）中补充燃烧，以及氢气全氧燃烧直接产生蒸汽。因此，我们首先在一个详细的非线性过程模型中模拟了一个典型 CC 工厂的性能。其次，我们拟合了一个代用的混合整数线性模型，该模型可以在较长的时间框架内（一年，每小时分辨率），在合理的计算时间内优化工厂的运行。通过该替代模型，可以对 CC 工厂的氢气燃烧改造进行深入分析，评估盈利能力和环境影响。研究结果表明，只有当氢气比天然气便宜时，在燃气轮机中直接燃烧氢气才具有经济可行性。虽然以天然气为燃料的管道燃烧器可以提高电厂的盈利能力，但同时也会增加特定的碳排放量。然而，在管道燃烧器中燃烧氢气并不符合成本效益。然而，在发电厂的蒸汽循环中加装氢氧燃料燃烧器，则可以提高发电和蒸汽生产的盈利能力和二氧化碳排放量。

Energy system modeling supports the identification of the optimal technology mix to achieve decarbonization targets across multiple sectors. Especially when sector coupling is considered for future technology landscapes, the large solution space leads to a complex optimization problem in terms of computational feasibility and data requirements. The authors identify a research gap in developing an open-source model structure with consideration of the relevant future technologies of power, heat, other conversions, transport, and industry defined with a new level of detail in a sector-coupled energy world and in including detailed insights into the accompanying definition process. A strong focus is set on the transparency and reproducibility of the provided open-source structure and its flexible and consistent application to different framework families to foster the ease of applicability of this work. The paper first gives a detailed description of the model base, including an overview of the model frame definition process, the core adjustments to model sector coupling appropriately, and the measures to make the resulting problem computationally feasible. The core result of this work is the presentation of a detailed model structure to model sector coupling for a German energy system, yielding approximately 2000 processes that characterize the heterogeneous and technology-open landscape of existing and possible future technologies across relevant energy sectors. This supports energy system modelers in understanding and reproducing energy system models based on open-source data and thereby tries to accelerate the research on sector coupling and its role in the energy transition.
