- World is heading towards the crisis of fossil fuel. Energy crisis is more acute in Bangladesh, as there is no petro-fuel source but only natural gas. It has among the lowest per capita energy (240 kg oil equivalents) consumption in the world and is severely dependent on additional environmentally friendly renewable energy resources in the future. To cope up with present situation and to reduce dependency on imported fuel, Bangladesh government is encouraging the use of renewable energy sources. In this circumstances, biofuel can be a very good alternative fuel for transportation. This paper gives insight into biofuel production feasibility and its usage for road transport can play an important role in the biggest metropolitan city of Bangladesh and contributes to knowledge on how to perform similar studies. Resource-focused assessment including feedstock from the waste sector, agricultural sector, forestry sector and aquatic environments partially considering technological and economic constraints. Sufficient evidence have been found for biofuel production and can met at-least 10% of energy demand for road transport of Dhaka city, Bangladesh. Without compromising with food security the study suggests that it is possible to significantly increase the biofuel production, and to do this as an integrated part of the existing society also contributing with positive societal synergies.

Forskningsöversikt (refereegranskat)abstract
- In 2019–2020, Bangladesh imported 5.2 million metric tonnes of petroleum products, worth 2.5 billion USD, and 50% of the imports were consumed by the transportation sector. Having limited natural oil reserves and being heavily dependent on oil imports, the country is vulnerable to shocks in the international oil market, which can jeopardize its consistent economic growth. The Government announced a 5% blending of bioethanol with gasoline in 2017, with broken rice, maize, and molasses as the feedstocks, but sourcing biofuel from food crops can hamper the country’s food security. This study explores second and third generation feedstocks e.g., organic plants, seeds, agricultural residues, and waste animal fat or skin that can be collected and processed for the extraction of biofuels. Technical potential of biofuel from the feedstocks is analysed which shows that Bangladesh has a potential to extract 44.4 million metric tonnes of bioethanol in a year from agricultural residues with rice residue having the highest potential (71%). Ground nut and rubber seeds can be major feedstocks for biodiesel production having a potential of 61,000 and 42,000 metric tonnes per year, respectively. Waste chicken skin can be another promising feedstock for the extraction of biodiesel. Biofuels extracted from these non-edible feedstocks and blended with existing transport fuels can lessen Bangladesh’s import bills through a sustainable, environmentally friendly manner.

Tidskriftsartikel (refereegranskat)abstract
- Industrial energy efficiency is acknowledged as a cost-effective mean contributing to sustainable development and industrial competitiveness. Implementing energy management practices becomes even more imperative for developing countries, considering their energy usage trends and economic development forecasts. Based on the circumstances, an empirical investigation is conducted on energy efficiency and management practices, as well as barriers and drivers to energy efficiency in the energy-intensive industries of Bangladesh. The study finds that majority of the companies barely implement the energy management practices. Energy audits represent the mostly implemented energy management practice at the industries, though a comprehensive approach on a detailed level is still lacking. In addition, this study finds that the number of dedicated and specialised energy professionals employed in the industries is yet negligible. The cumulated results show that energy efficiency is mostly disrupted due to inadequate support from preeminent administration and bureaucratic intricacy. Energy blueprint cost-saving due to less use of energy and rules and regulations were distinctively signified as most imperative drivers for energy efficiency. On the other hand, lack of information is found to be the most significant barrier to consult energy service companies. Analysis of the country's energy usage and supply-demand relationship points towards insufficient energy efficiency measures and energy management practices in the country. The study also finds that energy efficiency could be improved by 8%–10% through the practice of energy management. Our findings, besides pointing out specific issues to be tackled in the specific context of investigation, pave the way for further research over industrial energy efficiency in developing countries.

Tidskriftsartikel (refereegranskat)abstract
- Energy is considered as one of the significant benchmarks towards sustainable growth. Due to the recenteconomic growth, energy demand is increasing day by day in Bangladesh. The power generation mainlyrelies on fossil fuels though there are plans to increase the renewable energy share by the concernstakeholders. Considering the global warming, energy generation from renewable sources is consideredas a sustainable way to mitigate the anthropogenic emission. This study, therefore, addresses thepotentiality of biogas production from municipal waste and agricultural residues in a city territory ofDhaka namely Hazaribagh. The potential sources include wastes from two markets, six slaughterhouses,domestic wastes, one poultry farm and three croplands. The calculations made in this study to estimatethe amount of biogas and electricity from the described sources are done in a simple way, just to illustratethe potential. This study suggests that there is a good potentiality of biogas production and electricitygeneration from municipal wastes and agricultural residues of Hazaribagh. Moreover, this study alsomentions the significant actors like government, future owners, people and so on that are needed to beincorporated to implement biogas solution in a city territory.

The Cost Factor Analysis of Wind Power Plants-An Economic Perspective
- 2018
-
Konferensbidrag (refereegranskat)abstract
- Renewable energy can help the countries to meet their sustainable development goals. It provides provision of access to clean, secure, reliable and affordable energy. Renewable energy has gone mainstream, accounting for the majority of capacity additions in power generation today. Today wind power plant technologies are experiencing renaissance and the wind turbine promises to be an important alternative to fossil fuels in the future. Therefore, cost factors of the wind power plants have been analyzed in this paper in perspective of Sweden and Germany. The capital expenditure costs include material and labour cost for civil work, turbine installation and electrical connection. The most significant part among all is turbine installation. The revenue depends on the market price and financial support through government strategies and regulations. The analysis is based on a range of data sources of cost indicators – capital expenditure, operational expenditure, levelised cost of electricity and revenue. This paper is not a detailed financial analysis of project economics rather it provides simple and reliable information which can be used to evaluate the costs of different wind power projects.

Tidskriftsartikel (refereegranskat)abstract
- Bangladesh faced a substantial growth in primary energy demand in the last few years. According to several studies, energy generation is not the only means to address energy demand; efficient energy management practices are also very critical. A pertinent contribution in the energy management at the industrial sector ensures the proper utilization of energy. Energy management and its efficiency in the textile industries of Bangladesh are studied in this paper. The outcomes demonstrate several barriers to energy management practices which are inadequate technical cost-effective measures, inadequate capital expenditure, and poor research and development. However, this study also demonstrates that the risk of high energy prices in the future, assistance from energy professionals, and an energy management scheme constitute the important drivers for the implementation of energy efficiency measures in the studied textile mills. The studied textile industries seem unaccustomed to the dedicated energy service company concept, and insufficient information regarding energy service companies (ESCOs) and the shortage of trained professionals in energy management seem to be the reasons behind this. This paper likewise finds that 3–4% energy efficiency improvements can be gained with the help of energy management practices in these industries.
