Abstract

As the world adopts the technological era, the adverse effects of climate change have been experienced by the increasing population, which has led to a rise in energy demand. Heavy industries depend on dirty fossil fuels that release GHG emissions into the atmosphere. This paper aims to review the integration of a nuclear-renewable hybrid energy system (NRHES) to produce green hydrogen in decarbonizing hard-to-abate industries in the ASEAN region. In this study, the two main hydrogen production methods were identified, including thermochemical and electrolytic processes. The available renewable energy sources in ASEAN countries, such as solar, hydropower, biomass, geothermal, and wind, were also determined to evaluate the possible routes for coupling with nuclear power. Thus, considering the zero-emissions and baseload electricity from nuclear energy, integrating this with renewables in the region can accommodate their intermittent characteristics and supply the minimum electricity demand. This article suggests that as the region is rich in agriculture, nuclear-biomass is the most viable combination of energy sources to overcome different global issues. Furthermore, the prospects of hydrogen and its potential for industrial applications--mainly in transportation, manufacturing, chemical plants, and refineries--were presented in this analysis. This review determined the economic, technical, and societal impacts and policy frameworks of implementing NRHES for green hydrogen production to examine the possible challenges faced by Southeast Asia. Therefore, these challenges and gaps enable further exploration of the integration of NRHES to produce hydrogen as an alternative energy source. [ABSTRACT FROM AUTHOR]

2. Decarbonization Prospects in the Commonwealth of Independent States.

Abstract

The paper discusses existing trends and prospects for decarbonization in the Commonwealth of Independent States (the CIS), an international organization that regroups Armenia, Azerbaijan, Belarus, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan, Turkmenistan, and Uzbekistan. The CIS occupies a significant share of Eurasia, representing a large share of global energy consumption and production with a corresponding carbon footprint. These countries and their decarbonization prospects are rarely discussed in the English-language scientific literature. This paper fills in this gap by offering a comprehensive analysis based on statistical data, policy documents, and scenario-based future projections. The results underline that revisiting Nationally Determined Contributions, increasing energy efficiency, and decoupling GDP growth from greenhouse gas emissions are essential to the implementation of the Paris Agreement. The future energy mix should include larger shares of renewable energy, hydrogen, fossil fuels (highly efficient with carbon capture), and nuclear energy to achieve energy security and decarbonize the economy of the region in the long term.

Abstract

The dairy industry requires substantial energy resources at all stages of production and supply to meet consumer needs in terms of quantity, quality and food safety. The expected future climate change effects will cause serious uncertainty to the dairy industry. Adapting to these upcoming conditions is a challenge and one that is compounded by the continuous increase in food demand, as a result of global population growth. Predictably, under current conditions, this situation might lead to a significant increase in the energy requirements of the dairy industry. Therefore, there is a clear need to mitigate energy use through enhanced energy conservation, waste reduction and waste management. This review paper presents and discusses alternative dairy operations and mitigation strategies that have the potential to lead the dairy industry towards net-zero carbon emissions. Further, the focus of this work turns to supply chain energy modelling (SCEM) as means to mitigate energy use, while relevant work in the literature is reviewed. Supply chain energy models can provide a complete overview of the energy demand and the energy mix of a dairy supply chain. Additionally, they can highlight the most energy consuming processes and allow the evaluation of alternative energy-saving operations that can lead towards the net-zero carbon target. Overall, the development or use of computational tools for simulating the energy demand in the industry has strong potential for improving sustainability across the dairy supply chain. • Insight on climate change effects on the dairy supply chain and impact on energy demand. • Understanding the relevance and importance of the "net-zero" carbon emissions target in the dairy supply chain. • Identification of novel energy mitigation strategies across the dairy supply chain. • Importance of developing supply chain energy models (SCEM) to address energy mitigation in the dairy sector. • Evaluation of modelling techniques to develop or deliver supply chain energy models.
