“…It needs to be noted that the present study is unvalidated and does not consider true reaction kinetics. Nevertheless, a high CaO/C ratio realized within this study is comparable with the commonly reported values, such as the study by Magoua Mbeugang et al, 58 thus offering a good potential for CO 2 removal.…”

Summary In recent years, the field of biomass gasification as a method of transforming biomass into a more useable gaseous fuel experienced expedited development since it represents a prominent way to achieve sustainability goals and targets set by the Paris accord and, more recently, the European Green Deal. The use of natural gas is projected to reduce with the transition toward exploitation of renewable gas, while a new area of hydrogen applications is also emerging. However, with uncertain production of current processes, and consumption patterns seen on the market, an opportunity for a new flexible process exists. This article investigates a concept process design of sorption‐enhanced gasification (SEG) based on calcium looping. Aspen Plus simulation software was used to develop and simulate the process models for flexible production of bio‐SNG or bio‐H2. The process parameters can be manipulated to either achieve a high‐purity bio‐H2 (>96 mol%) or high‐purity bio‐SNG (>95 mol%), as well as any other combination of the two main products. The concept process is based on a low‐pressure, low‐temperature dual‐fluidized bed reactor with steam as a gasifying agent and an additional downstream Sabatier process reactor to achieve high CH4 contents. The simulated process achieves process efficiency of up to 62.2%LHV and 78.0%LHV for H2 and CH4 production, respectively, with production yields reaching 0.112 kg H2/kg BM and 0.23 kg CH4/kg BM. These values were validated and benchmarked against comparable process designs, and the performance of the proposed process was found to be on par or superior. Overall, the proposed process design exhibits clear benefits of calcium looping gasification, with high process efficiency, negligible NOx, SO2, and H2S content, and high flexibility. Therefore, the proposed process addressed and successfully solved some of the key challenges of achieving viability of a gasification plant on a commercial scale.

“…The obtained syngas could be used as fuel for heating and power generation or as an intermediate for the production of other fuels and chemicals, such as methanol, dimethyl ether and ammonia. Moreover, hydrogen-rich syngas can be produced from adsorption enhanced gasification [11,12] or obtained by the further conversion of CO in syngas [13] through water-gas-shift reaction. Fig.…”

“…Researchers have studied this process by using various feedstocks, and different sorbents under different operating conditions to investigate the process efficiency to accelerate pure hydrogen yield capturing CO 2 . Christian et al studied sorption enhanced gasification of cellulose and investigated the effects of CaO as a CO 2 absorbent as well as a catalyst on hydrogen production [140]. Their result showed that the activity of CaO depends on gasification temperature and in the 550-700 • C temperature range CaO acts as an absorbent as well as a catalyst whereas at ≥750 • C temperature it acts only as a catalyst.…”

Hydrogen is a source of clean energy as it can produce electricity and heat with water as a by-product and no carbon content is emitted when hydrogen is used as burning fuel in a fuel cell. Hydrogen is a potential energy carrier and powerful fuel as it has high flammability, fast flame speed, no carbon content, and no emission of pollutants. Hydrogen production is possible through different technologies by utilizing several feedstock materials, but the main concern in recent years is to reduce the emission of carbon dioxide and other greenhouse gases from energy sectors. Hydrogen production by thermochemical conversion of biomass and greenhouse gases has achieved much attention as researchers have developed several novel thermochemical methods which can be operated with low cost and high efficiency in an environmentally friendly way. This review explained the novel technologies which are being developed for thermochemical hydrogen production with minimum or zero carbon emission. The main concern of this paper was to review the advancements in hydrogen production technologies and to discuss different novel catalysts and novel CO2-absorbent materials which can enhance the hydrogen production rate with zero carbon emission. Recent developments in thermochemical hydrogen production technologies were discussed in this paper. Biomass gasification and pyrolysis, steam methane reforming, and thermal plasma are promising thermochemical processes which can be further enhanced by using catalysts and sorbents. This paper also reviewed the developments and influences of different catalysts and sorbents to understand their suitability for continuous clean industrial hydrogen production.
