“…The fixed cost includes insurance, maintenance, and labor wages, while the variable cost accounts for water, fuel, and the cost of electricity consumed. The equivalent operating hours is equal to 7500 h and the CCF is equal to 0.13 (corresponding to a plant lifetime of 15 years was considered with discount rate of 10%), consistent with [48,54].…”

Techno-Economic Assessment in a Fluidized Bed Membrane Reactor for Small-Scale H2 Production: Effect of Membrane Support Thickness

et al. 2019

This paper investigates the influence of the support material and its thickness on the hydrogen flux in Palladium membranes in the presence of sweep gas in fluidized bed membrane reactors. The analysis is performed considering both ceramic and metallic supports with different properties. In general, ceramic supports are cheaper but suffer sealing problems, while metallic ones are more expensive but with much less sealing problems. Firstly, a preliminary analysis is performed to assess the impact of the support in the permeation flux, which shows that the membrane permeance can be halved when the H2 diffusion through the support is considered. The most relevant parameter which affects the permeation is the porosity over tortuosity ratio of the porous support. Afterward, the different supports are compared from an economic point of view when applied to a membrane reactor designed for 100 kg/day of hydrogen, using biogas as feedstock. The stainless steel supports have lower impact on the hydrogen permeation so the required membrane surface area is 2.6 m2 compared to 3.6 m2 of the best ceramic support. This ends up as 5.6 €/kg H2@20bar and 6.6 €/kg H2@700bar for the best stainless steel support, which is 3% lower than the price calculated for the best ceramic support.

“…In this way, it is possible to state which route is most appealing for the conversion of this feedstock, but it is impossible to verify whether BG could represent a suitable alternative to natural gas. Analyzing the GWP for the production of H 2 starting from BG or BM, the impact of the production of a certain amount of hydrogen depends on the feed used and the technology applied for biogas upgrading [42][43][44][45][46].…”

Catalytic Upgrading of Clean Biogas to Synthesis Gas

et al. 2022

Clean biogas, produced by anaerobic digestion of biomasses or organic wastes, is one of the most promising substitutes for natural gas. After its purification, it can be valorized through different reforming processes that convert CH4 and CO2 into synthesis gas (a mixture of CO and H2). However, these processes have many issues related to the harsh conditions of reaction used, the high carbon formation rate and the remarkable endothermicity of the reforming reactions. In this context, the use of the appropriate catalyst is of paramount importance to avoid deactivation, to deal with heat issues and mild reaction conditions and to attain an exploitable syngas composition. The development of a catalyst with high activity and stability can be achieved using different active phases, catalytic supports, promoters, preparation methods and catalyst configurations. In this paper, a review of the recent findings in biogas reforming is presented. The different elements that compose the catalytic system are systematically reviewed with particular attention on the new findings that allow to obtain catalysts with high activity, stability, and resistance towards carbon formation.

Determination of the Potential Impact of Domestic Anaerobic Digester Systems: A Community Based Research Initiative in Rural Bangladesh

et al. 2019

This research examines the potential impact of domestic anaerobic digester (AD) systems adopted in Bangladesh and similar developing countries. Cattle dung and poultry litter feed stocks were specifically investigated, because these were freely available and plentiful to people living within agricultural areas of rural Bangladesh. Data was collected to ascertain whether these two representative AD facility types provide tangible social, economic and environmental impact that benefits homeowners. Primary quantitative and qualitative data was obtained by field data collection, and meeting with expert groups and stakeholders. Empirical analysis conducted revealed that variations were found in the biomass feedstocks available on different sites but also differences were apparent in terms of the operations and maintenance (O and M) systems of the biogas plants operated. The biogas and methane yield variation was also measured, and variations were found in the cattle dung and poultry litter AD yield capacity. Overall, 64% of feedstock was utilised, 91% of biogas plants remain underfed and energy yield efficiency was 57% from cattle smallholdings' AD and 28% from poultry farms' AD. These results showed that small scale AD can offer a significant impact upon rural lifestyles through augmented economics, improved social activities, relationship building with neighbours and improved lifestyle achieved via time savings accrued. These results could help rural entrepreneurs, AD equipment providers and government institutions to develop a road map to implement future AD installation on a much wider geographical scale.Processes 2019, 7, 512 2 of 14 economic growth has contributed to the public's insatiable demand for energy [3]. Within Bangladesh, agriculture represents the predominant source of industrial activity, and as a consequence, biomass is abundant, thus providing a natural source of biogas production. More than 70% of Bangladeshi citizens live and work in rural locations, yet only 62.4% of these people have access to electricity. The abundance of biomass provides an enormous opportunity to change lives and fuel further economic development. Indeed, the statistics are compelling, and circa 2016, there were 102.6 million tonnes of cow dung and 12.9 million tonnes of poultry litter literally going to waste [4].As a developing country, the literacy rate and gross domestic product (GDP) in Bangladesh is low, and this situation negatively impacts upon the new installation and maintenance of biogas plants [5,6]. Socio-economic issues often hinder progress towards sustainable development, and an analysis is required to gain a deeper and more meaningful understanding of these issues (e.g., support for communities). The national level biogas survey conducted in 2013 revealed that only 50% of occupants within households with biogas plants receive formal training about the operations and maintenance (O and M) of the plant, and often such constituents a mere day of training [5,7,8]. Given this prevailing socio-economic situation a...
