“…The fuel conversion processes that can be utilized are combustion and gasification [94]. There are several studies that have investigated the economic viability of implementing gasification technology in Nigeria for off-grid electricity generation [95][96][97][98]. It has been noted that there are resources and technologies available to sustainably deliver electric power to certain regions in a cost-effective manner.…”

Producing durable and efficient solid biofuels should be an important consideration in Nigeria’s present economy due to the numerous advantages associated with it. It offers the benefit of energy generation, particularly in rural areas, and could potentially replace fossil fuels. However, the adoption and production of solid biofuels at commercial scale in Nigeria is limited by some challenges, including the lack of a developed supply chain structure, inadequate facilities, and air pollution. The present study summarizes the types of solid biofuel production technologies deployed in Nigeria as well as the biomass feedstock utilized in the production of fuel briquettes and pellets. While opportunities exist in the gasification of biomass in Nigeria, direct combustion is a readily applicable fuel conversion process that can be utilized to generate electricity from solid biofuel. The major challenges surrounding the full adoption of solid biofuel production and utilization in Nigeria are highlighted. Among others, promotion of clean energy alternatives, investments and financial incentives, sustainable renewable energy policy and energy transition plan, and legislative backing are identified as factors that could accelerate the commercial production and adoption of solid biofuel in Nigeria.

“…Several research works have examined the potential benefits and implications of decentralized biomass gasification CHP plants for off-grid power supply systems located in remote areas. For example, Ejiofor et al [24] conducted a load assessment of an offgrid gasification power supply option for eastern Nigeria fueled with rice husk. The gasification system was designed and sized based on the mass flow rate of producer gas required to power the gas engine at full load; however, it was not experimentally tested.…”

A substantial number of off-grid olive oil mills in Morocco are powered by diesel-fired generators, which hugely contribute to air pollution and greenhouse gas emissions. In this research work, a biomass gasification combined heat and power (CHP) plant fueled with local by-products was explored as a renewable alternative to electrify off-grid olive oil mills in this country. The case study considered a gasification CHP plant with a rated power of 80 kWe, in order to enable adaptation of the producer gas flow rate to abrupt changes in the power generation unit under dynamic operation. A downdraft gasifier and a producer gas conditioning unit were modeled under steady state operation using Cycle-Tempo, while the power generation unit was modeled in the Thermoflex simulation environment under partial and full load operation. Olive cake pellets and olive pruning chips were evaluated as biomass feedstock, with moisture contents ranging from 5% to 20% (wet basis). The results from the simulation of the gasification CHP plant showed net electrical efficiencies and CHP efficiencies around 18% and 35%, respectively. Finally, a profitability assessment of the gasification CHP plant was developed for 2 months of continuous operation, together with a sensitivity analysis. The results for the baseline scenario reveal a payback period of 7–8 years and a 68.5% accumulated profit based on the capital investment, which suggest that biomass gasification CHP plants can represent an economically feasible and sustainable solution for the electrification of off-grid areas in Morocco.

“…Rice is one of the potential commodities as a source of producing bioenergy [1][2][3], In the process of grinding the main product produced in the form of rice as a staple food, while waste from the grinding process in the form of rice husks is the main ingredient potentially used as bioenergy [4][5][6][7][8][9][10][11]. In general, bioenergy is available in liquid forms such as bioethanol and Biodiesel, in the form of gas as biogas, and solid in the form of Briquettes and Biobrilles and Pellets.…”

Decision on location determination for rice-based Bioenergy Agro-industrial area is one part of the efforts to develop the bioenergy supply chain. The development location is selected based on the criteria set by the government. This study aims to plan the model of determining the location of agro-industrial supply chain development area of Rice-based bioenergy as well as evaluate the important criteria that need to be considered in the selection of the location of a bioenergy agro-industry so that alternative locations can be obtained from several potential locations that are targeted for rice-based bioenergy agro-industry development areas in Banten province of Indonesia. By using the fuzzy logic-AHP method approach, it is expected to obtain a decision model based on multi-criteria with a hierarchical process. The result of this study is the most optimal district used as the location of development of rice-based bioenergy agro industry area in Banten Province is Lebak Regency with the highest weight value 0,4328. Based on the results of research proposals for further research this method can be applied to the development of other bioenergy agro-industry, taking into account the criteria of spatial aspects based on geographical factors as well as appropriate alignment in an industrial area.
