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]

The concept of a "passive House" has been introduced for the first time in Germany, subsequently being extended and at higher latitudes and different features climatic from those of Germany, in the south, west and south-west of Europe. Passive building has been defined by Wolfgang Feist, Passivhaus Institut, as being the building that demand for heating must not be more than 15 kWh/m2 year, and total consumption of primary energy should not be more than 120 kWh/m2 year. In this paper we strive to study at the concept of 'passive house' in the Russia. Using the Passive House Planning Package (PHPP) software 2007 calculate the heating requirements for such a House, depending on the latitude and climate conditions in the locality. For the study were selected 7 cities from Russia placed to different latitudes and climatic areas. To determine the possibility of implementing the concept "passive House" must be determined: required heating, cooling demand and primary energy demand. In order to implement this concept should not exceed maximum limits. [ABSTRACT FROM AUTHOR]

The main objectives of each of cities from Romania are sustainable development, energy efficiency, use of renewable energy and ensuring a clean and healthy environment for citizens in a modern city, attractive, prosperous and a high standard of living. The climate changes, increasingly present every day in the realities of city, mainly caused by human factor, obliges us to a new approach and orientation responsible for the future of our decisions in order to rational and efficient use of resources, especially in order to combate, to reduce and adapt to climate change. The way we intervene to reduce emissions of greenhouse gases, to mitigate and adapt to climate change defines us, placing us among European citizens informed, responsible and active. Renewable energy and biomass energy, a type of renewable energy, are one of the issues that have been overemphasized since the 1990s. The fact that the countries of the world turned to renewable energy sources from fossil fuels and diversified their energy sources, the increasing importance of renewable energies in the energy security context, the lack of stability in energy prices, the fact that the countries adopted growth strategies based on local dynamics, the source of which they had in their lands, reducing transportation costs, alternatives to generate electricity were among the factors that brought this issue to the agenda of the world and made the scientists conduct studies on the issue. Biomass energy that is one of the renewable energy sources is an important energy source particularly for developing countries, and the production and use of it are increasing every day. Considering the geographic features of the region, the use of biomass for bio-economy development, comes naturally. In order to create a business model for the use and integration of biomass supply- chain, this study will focus on providing an overview on the current state of biomass availability and usage in West Region of Romania, as well as providing brief presentation of roadblocks for further development of biomass supply chains. Also, the focus will be on developing transnational interactions that could be a solution to biomass development in the region. In that sense, the target of the next chapters is to assess the energetic potential of existing biomass in Western Region, and the necessary features of the supply chain, needed in order to develop a sustainable business in biomass field. In this paper it will be estimated potential production of biogas from residues and waste for the western region of the country. To accomplish this is necessary to identify the types of wastes and wastes that can be used. Identification will be made by name, quantity, the theoretical potential of biogas and waste to flow through the availability of energy use. Consideration should also be given to the methods of using these wastes and wastes time. [ABSTRACT FROM AUTHOR]
