“…Poland does not have its own standards defining the quality of biomass used for energy purposes. "Noble biomass", a term commonly used by power engineers, refers to pellets made from various types of biomass and is defined based on compliance with the German standard DIN 51731 [59], which applies to natural wood pellets [60].…”

The torrefaction process represents a thermal conversion technique conducted at relatively low temperatures ranging between 200 to 300 °C. Its objective is to produce fuel with a higher energy density by decomposing the reactive portion of hemicellulose. In this study, the kinetics of mass loss during torrefaction were investigated for willow. The experiments were carried out under isothermal conditions using thermogravimetric analysis. Batch torrefaction reactor designs were conducted and explained in detail. Co-combustion of willow with hard coal (origin: Katowice mine) in different mass ratios (25% biomass + 75% coal, 50% biomass + 50% coal, and 75% biomass + 25% coal) was conducted in addition to raw biomass torrefaction. TG/MS analysis (a combination of thermogravimetric analysis with mass spectrometry analysis) was performed in the research. The optimal torrefaction conditions for willow were identified as an average temperature of 245 °C and a residence time of 14 min, resulting in the lowest mass loss (30.15%). However, it was noted that the composition of torgas, a by-product of torrefaction, presents challenges in providing a combustible gas with sufficient heat flux to meet the energy needs of the process. Prolonged residence times over 15 min and higher average temperatures above 250 °C lead to excessive energy losses from volatile torrefaction products, making them suboptimal for willow. On the other hand, the co-combustion of torrefied biomass with hard coal offers advantages in reduced sulfur emissions but can lead to increased NOx emissions when biomass with a higher nitrogen content is co-combusted in proportions exceeding 50% biomass. This paper summarizes findings related to optimizing torrefaction conditions, challenges in torgas composition, and the emissions implications of co-combustion.

“…A small-scale bio-pellet production facility using empty fruit bunches waste from palm oil mill has shown a good economic feasibility, which can compete with the biomass briquets, wood and coal selling prices in the local market in Indonesia [90]. It was shown experimentally that high quality wood pellets can increase the efficiency of gasification and the quality of the gas product considerably [91]. For low-quality raw biomass with high moisture content (above 50%) such as bagasse waste from sugar production industry, low temperature torrefaction (at 150°C) was found to be feasible with acceptable product quality that can be used efficiently for gasification or direct combustion [92].…”

Government policies in Indonesia have been pushing in the past decade towards 100% electrification target by end of 2020. However, many of the new energy policies are reused from previous policies designed for different objectives causing overlap in policies between the central and local governments. Local distributed generation are not fully controlled by local stakeholders and community, and with the lack of long-term planning, continuous government incentives and support, they are bound to fail due to the lack of maintenance. The use of solid biomass for household has decreased significantly due to the government support for LPG stoves that overtaken other government projects supporting biomass. Small-scale biomass research is showing good progress towards the implementation of novel methods for biomass utilization. However, majority of the medium and large-scale projects are still relying on old technologies such as direct biomass combustion in boilers rather than the more environment friendly gasification technology. Another major biomass contribution to national energy mix is through liquid biofuels. This work summarizes the current and prospective energy mix in Indonesia and the main conventional and non-conventional energy sources and their environmental concerns. This work also gathers the latest local biomass research and biomass power plant projects.

The drive towards renewable energy become intense nowadays due to the increasing price of fossil fuels and depletion of their sources. Among promising resource of renewable energy is the biomass. In Malaysia, oil palm biomass are available in large quantity and suitable for conversion into value added bio-fuels. In this study, an-innovative small-scale downdraft gasifier was designed, development and tested for biomass gasification. The gasifier operates at flowrate less than 0.1 m 3 /s with a capacity of 5 KW. During testing and commissioning of the gasifier, the maximum efficiency of the gasifier was found to be about 71% when firing empty fruit bunch pellets. This gasifier has potentials to be up scaled for actual use either for domestic or industrial use.
