Direct firing of biomass in conventional clay brick manufacturing process aggravates deforestation, climatic change, poor economic benefits to rural industries, and health issues to the public. To overcome such drawbacks, adaptation of ecofriendly energy sources, implementation of advanced technologies in energy conversion systems and systematic studies on economic benefits are mainly focused in recent times. The utilization of biomasses through various gasification technologies can improve the energy efficiency and economic advantages of brick production. To successfully introduce renewable energy systems and new technologies in rural areas, a number of research studies have experimented and also succeeded in predicting the technical feasibility and cost benefits. Likewise, this paper reports the techno-economic analysis of producer gas (PG) fired brick kilns using pertinent parameters of evaluation involved in the manufacturing of bricks. In this study, the common biomasses available in the region were effectively used to produce PG. Besides finding the technical aspects of bricks produced through this method, the parameters needed for economic study were found from a prototype experimental study. The economic parameters to use agriculture and forestry biomasses such as Coconut Shell (CS), Rice Husk (RH), Rubber Wood (RW) and Rubber seed kernel shell (RSKS) in conventional industries for a capacity of twenty to one hundred thousand bricks per batch were predicted. The studies revealed that the quality of bricks produced from the proposed method could meet ASTM standards. The savings in the running cost of the proposed system led to 4-8 years payback period. The maximum internal rate of return was found from the system which had RSKS as feedstock.

The current climatic and geopolitical situation leads to strong decarbonisation policies in several industries worldwide. Moreover, the European Union is pushing intensive industries to achieve a 55% reduction in CO2 emissions towards 2030. Among them, the steel manufacturing sector is at the lead of alternative projects that can help achieve this ambitious target. Co-production of syngas and biochar is one potential solution for this sector. Herein, a techno-economic analysis is provided to evaluate the economic feasibility and the effect of the most influential parameters for a successful deployment. A bibliographic review has been carried out to establish a clear baseline for such an analysis in terms of investment costs at several scales for gasification projects. Additionally, the cost evolution for coke, natural gas, and CO2 emission credits on the profitability of these projects are given. The case scenario processing 20,000 tbiomass/y is the most feasible solution, with a payback of around three years and a net present value (NPV) of around 15 million EUR, showing that biomass gasification can be an up-and-coming alternative in the mid-term.

“…Several studies tried to evaluate the economic profitability of biomass gasification CHP plants [89][90][91][92][93][94]. Colantoni et al [89] used Montecarlo simulation to evaluate important economic indicators, like Net Present Value (NPV), Internal Rate of Return (IRR) and Payback Time (PBT), of three different gasification CHP power plants (13.6 kW, 136 kW, and 1.9 MW nominal electrical capacity). Small scale CHP sizes (13.6, and 136 kW) showed a PBT of 13.6 and 6 years, respectively.…”

Literature and manuals refer to biomass gasification as one of the most efficient processes for power generation, highlighting features, such as residual biomass use, distributed generation and carbon sequestration, that perfectly incorporate gasification into circular economies and sustainable development goals. Despite these features, small scale applications struggle to succeed as a leading solution for sustainable development. The aim of this review is to investigate the existing technological barriers that limit the spreading of biomass gasification from a socio-technical point of view. The review outlines how existing technologies originated from under feed-in-tariff regimes and highlights where the current design goals strongly differ from what will be needed in the near future. Relevant market-ready small-scale gasification systems are analyzed under this lens, leading to an analysis of the reactor and filtration design. To help understand the economical sustainability of these plants, an analysis of the influence of capital expenditures and operating expenditures on the return of investment is included in the discussion. Finally, a literature review on prototypes and pre-market reactors is used as a basis for spotting the characteristics of the system that will likely resolve issues around fuel flexibility, cost efficiency and load variability.
