“…This paper concerns only natural aspects of future wood energy use. As for technical and economical solutions, recent studies [22][23] stated that the current energy policies need to be examined before biomass is implemented on a larger scale to incorporate proper infrastructure, to assess the governmental support and to encourage partnership between wood industry and power producers.…”

Biofuels are an important energy source, currently providing about 10% of the world energy demand, including 2% of global electricity generation and the same share of total liquid fuel consumption. Wood fuel in Russia is one of the most affordable and most important type of renewable energy resources. In this paper we study the possible changes in energy potential of Russia's forest resources as a result of changes in the atmosphere and climate. The estimates of the global dioxide concentrations dynamics and mean annual air temperature change over the Russian territory for the period up to 2050 are developed using the MPEI models of the carbon cycle and regional climate. The calculations show that the change of net primary productivity of forests of Russia as a result of the CO2 abundance increase in the atmosphere, as well as of the increase of the air temperature and rainfall will enhance available energy resources of wood fuel by mid-century by more than 9 million tons of coal equivalent (Mtce).

Growing popularity of biomass power generation process is connected to its label of green and cheap renewable energy. As the second-largest producer of crude palm oil, Malaysia has abundance of biomass residues from palm oil industries and other renewable organic matters which can be converted to bio-chemicals to generate electricity. However, despite institutional arrangements, policy frameworks, funding mechanisms and incentives to support the growth of the biomass industry, there are several risks which may prone to reduce efficiency of biopower boiler especially empty fruit bunch as the fuels that cannot be ignored. Boiler is one of the primary equipment of power generation plants, in a significant role in converting biofuel to electricity. With increasing numbers of potentials of biomass as raw materials for renewable energy uses, new risks may be found. Yet there has been very little research into these risks and how to prevent them. Lack of understanding of modern risk identification methods, such as HAZOP, with the biopower industry is one of the reasons for the industry’s slow growth. An industry evolves through life cycle stages and at each stage presents risk factors such as overheating, oxygen corrosion and clinker. This paper identifies several key risks associated with EFB fired biopower boiler in Malaysia. The overview of risks not only provide a perspective from which an industry’s viability can be evaluated but also help the operators to better understand key risks and improve boiler capacity as well as plan their risk mitigation strategies more effectively.

“…While some authors (e.g., Hanif 2018 ; Mulugetta 2008 ) see the persistent use of biomass resources as energy sources critical and suggest a focus on other renewable energy sources, others (e.g., Berhanu et al 2017 ; Tucho and Nonhebel 2015 ) highlight the high potential of the same, in particular biomass-based energy as affordable energy sources in rural areas, where poverty is an obstacle to purchasing electrical equipment. From the latter’s viewpoint, woody biomass residues may represent an environmentally friendly and cost-effective alternative to fossil fuels for generating affordable biomass-based modern energy products in countries well-endowed with plantation forests (Dahunsi et al 2020 ; Nzotcha and Kenfack 2019 ; Shan et al 2016 ; Sulaiman et al 2020 ).…”

“…In addition, the conversion of previously used raw materials (e.g., residues or dung) and waste into biofuels increases the energy efficiency of the energy carriers themselves even further (Lee et al 2019 ; Tucho and Nonhebel 2015 ). A more recent economic valuation study by Nzotcha and Kenfack ( 2019 ) indicated that the use of woody biomass residues for power generation has the potential to enhance the SSA region’s current electricity-generation capacity by 1%. SSA has very low electricity access rates (45.4% in 2018), but it has a high potential for biomass-based energy systems because of the availability of ample raw material resources (IEA 2019 ).…”

Production of value-added outputs from biomass residues represents an opportunity to increase the supply of renewable energy in Ethiopia. Particularly, agroforestry could provide biomass residues for improved bioenergy products. The aim of this study was to characterize the interest of growers to provide biomass residues to a hypothetical biomass feedstock market. This study relied on a survey conducted on a sample of 240 farmers. Although the awareness of potential biomass products was generally quite low, a majority of farmers expressed interest in supplying biomass residues, but the level of interest depended on certain individual socio-economic and demographic characteristics. For example, younger and female household heads were found to be more interested in participating in the hypothetical biomass market, as were households with an improved biomass stove, larger land holdings, and higher income levels. In addition, larger households and those that felt less vulnerable to firewood scarcity also expressed more interest. As a whole, the results imply that farmers, particularly those with younger and female heads of households, should be supported with programs tailored to ensure their inclusion in biomass supply chains. Respondents generally preferred farm-gate sales of biomass, so the collecting, baling, and transporting of woody residues need to be properly incentivized or new actors need to be recruited into the supply chain. Providing households with energy-efficient tools such as improved stoves would not only increase demand for biomass products, but also increase the amount of biomass residues that could be supplied to the market instead of used at home.
