“…The major share in the FIC is associated with the gasifier (nearly 67%). It is within the range reported for technologies with similar capacity and goal sector 33 . The share of cost for the catalytic system is considerably lower than other cleaning system alternatives based on physical methods (gas scrubbing).…”

The present work is focused on the use of Jatropha curcas biomass (shell), as feed to gasification systems coupled to a diesel engine for electricity generation. The scope of this research is to analyze the environmental and economic effects of the integration of a gasification system to a biodiesel plant. The environmental impacts are quantified by a Life Cycle Assessment and the economy is assessed based on the Net Present Value, Internal Rate of Return, Investment Recovery Period models and the Levelized cost of electricity. The results demonstrate that a gasification system, using this biomass as a source of electricity generation, is a promising alternative for energy supply, with good economic effect. Estimated efficiencies are: Net Present Value > 0, Internal Rate of Return > 10%/yr and Investment Recovery Period = 2.08 years, representing very good outcomes for this kind of system. Nevertheless, the project exhibits a very low Levelized Cost of Electricity of 0.054 USD/kWh. From the environmental point of view, there is not critical step during the whole life cycle of electricity generation from Jatropha curcas biomass.negative environmental impacts were found for breathing-inorganics and acidification-eutrophication, but both at negligible levels.

“…The economic viability of biochar production systems depends on various parameters including the feedstocks used, the production technologies, and subsidies through carbon sequestration [143][144][145][146][147]. The size and scale of the biochar system also affect the cost and economic feasibility of biochar.…”

The increasing deforestation with an alarming rate is the prime cause of upsetting the balance in the natural ecosystem and the livelihood of local communities. Sustainable forest management and reforestation efforts can equilibrium this destruction and maintain the protected areas. In this regard, soil management strategies for reforestation of the degraded forest land can be helpful. In this review, the potential of using biochar, a solid carbon rich product of biomass thermochemical conversion, as a soil amendment in forest soils has been discussed. The production procedures of biochar, availability of feedstocks and the biochar properties are discussed using the existing knowledge. The positive effects of biochar are soil quality depended and change with varying geographical locations. Therefore, long-term field trials examining a range of biochars, soils, and forest types are required for a better understanding of this issue. Careful planning to match biochar with the soil properties is essential to obtain maximum benefits of biochar as a soil amendment.

“…Table 1 shows an overview of LCC calculation methods and the external cost quantification model. The calculation methods of LCC include the net present value (NPV), the internal rate of return (IRR), and the levelized cost of energy (LCOE) [14][15][16]. The NPV can be used in a single case or cases of consistent scales for comparison.…”

Economic cost is decisive for the development of different power generation. Life cycle cost (LCC) is a useful tool in calculating the cost at all life stages of electricity generation. This study improves the levelized cost of electricity (LCOE) model as the LCC calculation methods from three aspects, including considering the quantification of external cost, expanding the compositions of internal cost, and discounting power generation. The improved LCOE model is applied to three representative kinds of power generation, namely, coal-fired, biomass, and wind power in China, in the base year 2015. The external cost is quantified based on the ReCiPe model and an economic value conversion factor system. Results show that the internal cost of coal-fired, biomass, and wind power are 0.049, 0.098, and 0.081 USD/kWh, separately. With the quantification of external cost, the LCCs of the three are 0.275, 0.249, and 0.081 USD/kWh, respectively. Sensitivity analysis is conducted on the discount rate and five cost factors, namely, the capital cost, raw material cost, operational and maintenance cost (O&M cost), other annual costs, and external costs. The results provide a quantitative reference for decision makings of electricity production and consumption.
