“…Furthermore, the majority of respondents expressed reservations about the drawbacks associated with heating equipment fueled by woody biomass, such as its complex operation and high costs [53]. In contrast, public willingness for indirect utilization was remarkably high, especially in public facilities such as hot springs and welfare facilities [55,56]. Additionally, the unique capabilities of woody biomass heating equipment [46,49] and awareness of forests, the environment, and local regions [55,56] are the primary reasons why the public is willing to utilize woody biomass.…”

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.

“…Economic evaluations of power generation with gasification [28][29][30] and heat utilization [31,32] using wood chips as fuel have been reported in the literature; Seppä et al have evaluated the economics of a small-scale CHP (0.1-8 MW e , a downdraft gasifier combined with an internal combustion engine) using local wood, forestry by-products, and agricultural residues as fuel [28]. The feasibility of CHP was evaluated under three cases: 1. district heating CHP plant, 2. electricity and steam production in the wood industry, and 3. small steam plant as an alternative to a fuel oil plant.…”

“…Woodchip drying heat requires a lot of energy demand. Gasification CHP [28], woodchip boilers [31,32], and organic Rankine cycles [33][34][35] were identified as candidates for systems to provide the heat for woodchip drying. So far, these systems have been evaluated separately for their economic feasibility on their energy systems.…”

Among decentralized small-scale biomass energy sources with the potential to revitalize local communities, combined heat and power (CHP) from gasification is promising in terms of its high power generation efficiency. Still, it has yet to achieve operational stability, in part due to the variation in the moisture content of the woodchips used as fuel. In this study, a technical and economic evaluation was performed to establish a center for the efficient production of high-quality dry woodchips within a sawmill and to determine the technical characteristics and economic viability of a system using gasification CHP, wood waste-fired boilers or an organic Rankine cycle (ORC) as heat sources. The results showed that the net present values (NPVs) of gasified CHP, wood waste-fired boilers and ORC were −186 million, −402 million, and −103 million JPY, respectively. None of them were deemed profitable. Therefore, a sensitivity analysis was performed to determine the impact of low-quality wood prices, dry woodchips, heavy oil A, and the grid electricity charge on the NPV. The improvement of the low-quality wood price and dry woodchips sales price was effective for heat supply by gasification CHP and ORC turbines, and their combination was effective for woodchip-fired boilers.
