“…This paper utilises the Malaysian Agriculture and Plantation Greenhouse Gas Equilibrium Model (MAPGEM), a PE model. Researchers have utilised MAPGEM to assess the economic feasibility of biodiesel [9], biobutanol [10], bioelectricity [11], and bioethanol [12]. MAPGEM is written in the General Algebraic Modeling System (GAMS) and consists about 38,000 equations.…”

The economic feasibility and technological improvement to produce biodiesel from microalga, Chlorella vulgaris is investigated. The biodiesel would help Malaysia replace diesel with renewable and sustainable energy in the transportation sector. Accordingly, the Malaysian Agriculture and Plantation Greenhouse Gas Model is modified and extended to incorporate algal farms. The model forecasts Malaysia’s market prices and quantities of major agricultural commodities between 2024 and 2064. The state of the art is a commercial algal biodiesel industry is incorporated into a price endogenous model of Malaysia’s agriculture, and algal farms can experience technological improvement. The simulation results indicate that algal biodiesel is not economically feasible. The biodiesel price must be RM2.80 per litre or higher for the algal farms to produce biodiesel. The biodiesel price could be lowered to RM0.60 per litre if the algal farms experience a one-percent annual boost in either algal harvest yield or productivity gain. The results indicate that harvest yield improvements boost biodiesel production more than productivity improvements. The feasibility depends on algal farms to process the leftover slurry and supply the domestic animal feed markets. At last, the biodiesel offsets CO2 transportation sector emissions while the alga recycles the CO2 from fossil fuel electric power plants, which help Malaysia sequester high levels of CO2.

“…For example, on the European market, in 2022, the cost of biomethane production was 80 EUR/MWh, comprising 16 EUR/MWh (raw material), 32 EUR/MWh (CAPEX), and 32 EUR/MWh (OPEX) [125]. However, it should be considered that the costs depend on the availability of wastes in a local market, regional agricultural conditions, costs of feedstock, kind of feedstock and its form (raw waste or silage), the local retail prices, local policy scenario, production scale, available technologies, type of pretreatment, methods or substrates that, for example, increase the available sugars, biogas upgrading, and optimization of the fermentation process including the application of genetic engineering of microorganisms or the use of enzymes [126][127][128][129][130][131][132].…”

The conversion of lignocellulosic agricultural waste into biofuels and other economically valuable compounds can reduce dependence on fossil fuels, reduce harmful gas emissions, support the sustainability of natural resources, including water, and minimize the amount of waste in landfills, thus reducing environmental degradation. In this paper, the conversion of agricultural wastes into biomethane, biohydrogen, biodiesel, bioethanol, biobutanol, and bio-oil is reviewed, with special emphasis on primary and secondary agricultural residues as substrates. Some novel approaches are mentioned that offer opportunities to increase the efficiency of waste valorization, e.g., hybrid systems. In addition to physical, chemical, and biological pretreatment of waste, some combined methods to mitigate the negative effects of various recalcitrant compounds on waste processing (alkali-assisted thermal pretreatment, thermal hydrolysis pretreatment, and alkali pretreatment combined with bioaugmentation) are evaluated. In addition, the production of volatile fatty acids, polyhydroxyalkanoates, biochar, hydrochar, cellulosic nanomaterials, and selected platform chemicals from lignocellulosic waste is described. Finally, the potential uses of biofuels and other recovered products are discussed.

“…Forecasting models for energy consumption have become especially important in the face of the growing recognition of the need to move away from fossil fuels and to adopt renewable energy sources [14]. There are certain questions regarding the feasibility of replacing traditional sources of energy with alternatives or renewables [15][16][17]. Enhanced accuracy in forecasting allows decision makers to obtain valuable information in complicated and uncertain contexts.…”

Electricity generation in Taiwan is mainly from thermal, nuclear, and renewable sources. With nearly four decades of monthly data (from January 1982 to January 2022) used in analytics, the forecasting results reveal the patterns of electricity generation in Taiwan. Exponential smoothing and Holt–Winters seasonal models are used for time‐series forecasting, and scenario analysis is applied to simulate possible paths for nuclear phase‐out in Taiwan by 2025. Taking the fact of Taiwan's lack of energy independence into account, transition for nuclear phase‐out may require a substantial leap to meet the demand. The feasibility of electricity generation using current thermal power capacity and renewable energy remain challenging.
