“…In general, eight percent of the estimated value published by the Japan Agency for Natural Resources and Energy was used for the IRR. In many cases, the payback period is based on the 15-year legal life of a power generation facility or the 20-year FIT project period [57,58]. The evaluation of the balance between income and expenditure is relatively simple, and a business is judged viable if it does not generate a deficit [59].…”

After nearly a decade of rapid development, woody biomass has been widely used in Japan for power generation and heating. However, it has faced bottlenecks in recent years, leading to a decline in its popularity. This study aimed to elucidate the current status of woody biomass utilization in Japan by reviewing relevant research papers on upstream resource supply and downstream case studies in the supply chain. The supply potential of woody biomass estimated by reviewed articles ranges from 1.2 to 5.5 m3/year/ha, yet a significant portion of this potential cannot be exploited. The utilization of government subsidies, mechanization, and aggregated forests can substantially enhance the availability. The utilization of woody biomass has garnered widespread attention from the Japanese government and private enterprises, presenting an economic impact ranging from 66 to 249 million JPY/t, along with a GHG emission reduction spanning from −17.29 to 202.44 kg-CO2eq/GJ. However, balancing cost and scale remains the primary challenge facing woody biomass utilization in Japan.

“…A previous study estimated the availability of woody biomass in Japan to be about 400 PJ, or 40% of the total biomass available. An approximate calculation suggests that about 10% of Japan's primary energy supply could be provided by forests if all the tree growth in 240,000 km 2 of Japanese forests were used to provide energy [30]. Japan is close to 70% of its land is forested [31] and has a diverse range of crops, as shown in Figure 4, and has the sixth largest potential biomass market in the world [28], but forestry productivity in Japan is low, despite high forest potential and abundant reserves [32].…”

“…Due to the introduction of FIT, the installed capacity of renewable energy is growing rapidly [33]. In addition, it has been shown that in Japan, heat production is feasible for small-scale biomass energy use of 2660 t/yr or higher, and electricity generation is feasible for large-scale biomass energy use of 13100 t/yr or larger [30].…”

As the depletion of fossil fuels becomes increasingly severe, it is crucial to find alternative and sustainable sources of energy. Biomass, which is the largest renewable energy source in the world, is considered an effective solution to the problem of fossil fuel scarcity due to its sustainability, eco-friendly nature, and the wide range of raw materials available. This paper analyzes the current energy situation, energy policies, opportunities, and challenges of biomass energy development in several countries across Europe, Asia, and America. Based on the research results, most countries are proactively seeking to transform their energy systems to ensure sustainable economic development, particularly by utilizing solid biomass, which includes the recycling of industrial and agricultural residues and the cultivation of energy crops. However, biomass energy also faces challenges such as the impact on biodiversity, complex production processes, and high costs.
