“…The size of ES particles in Fertipaq was ∼5 by 10 μm, smaller than the ones in ES powder (67 μm on average), hence explaining the higher oxidation rate found for Fertipaq than for ES powder, either broadcast or mixed into the soil. The rapid oxidation of diluted and mixed Fertipaq (half‐life: ≤31 d) corroborated the results from a pot experiment in which diluted Fertipaq applied in a layer at 7 cm depth was totally oxidized and taken up by an oilseed rape crop within 70 d after application (Fontaine et al., 2021). From our results, we did not find any direct evidence that the hydrophilic character of the biological ES enhanced the oxidation rate, as suggested by Kleinjan et al.…”

“…(Janssen, Lettinga, & De Keizer, 1999; Kleinjan, Keizer, & Janssen, 2003). Biological ES has already been demonstrated to be an effective S fertilizer for plants with high S requirements such as oilseed rape ( Brassica napus L.)

Elemental sulfur (ES) is commonly used as a fertilizer S source but needs to be oxidized to sulfate to become plant-available. We assessed how placement (surface applied or incorporated) affects the oxidation of ES fertilizers. The fertilizers included an ES powder, a suspension of biogenic ES particles, and three granular fertilizers: two ES-bentonite pastilles and one monoammonium phosphate fertilizer cogranulated with ES. The fertilizers were applied either on the surface (broadcast) or incorporated into two different soils in a column experiment, incubated at 25˚C.Prior to broadcasting, the granular fertilizers were dispersed in water for 48 h to simulate the effect of 30 to 40 mm of precipitation. The columns were leached weekly and the concentration of sulfates derived through ES oxidation was measured in the leachates. The half-lives of oxidation for the ES powder were 76 and 111 d for the incorporation and broadcast applications, respectively. The diluted biological ES suspension showed faster oxidation (8 and 30 d for incorporated and broadcast), probably because of its smaller particle size. Unlike the ES particles, the ES oxidation rates of the granular fertilizers were higher for the broadcast application than when incorporated in soil, particularly when they dispersed easily. One type of ES pastille showed little dispersion and its estimated half-life of oxidation was >1,000 d even when broadcast. Overall, the results show that ES oxidation depends on the degree of dispersion in the soil and that this is strongly affected by the fertilizer type and application method.

“…Experimental works in the literature have studied bioethanol, − glycerol, − bio-oil from biomass pyrolysis, − or biogas , as feedstock. Biogas is a versatile raw material with a high potential to be utilized in reforming processes since it can be used as an alternative renewable source of CH 4 . , Increasing interest in biogas also arises from reducing the dependence on fossil fuels and greenhouse gas emissions; therefore, hydrogen production from biogas has great potential in a future-to-be CO 2 neutral or negative economy . Biogas is produced from biomass, residues, or wastes by anaerobic digestion, being the gas generated in landfill sites also named biogas.…”

Renewable clean H2 has a very promising potential for the decarbonization of energy systems. Sorption enhanced steam reforming (SESR) is a novel process that combines the steam reforming reaction and the simultaneous CO2 removal by a solid sorbent, such as CaO, which significantly enhances hydrogen generation, enabling high-purity H2 production. The CO2 sorption reaction (carbonation) is exothermic, but the sorbent regeneration by calcination is highly endothermic, which requires extra energy. Biogas is one of the available carbon-neutral renewable H2 production sources. It can be especially relevant for the energy integration of the SESR process since, due to the exothermic sorption reaction, the CO2 contained in the biogas provides extra heat to the system, which can help to balance the energy requirements of the process. This work studies different process configurations for the energy integration of the SESR process of biogas for high-purity renewable H2 production: (1) SESR with sorbent regeneration using a portion of the produced H2 (SESR+REG_H2), (2) SESR with sorbent regeneration using biogas (SESR+REG_BG), and (3) SESR with sorbent regeneration using biogas and adding a pressure swing adsorption (PSA) unit for hydrogen purification (SESR+REG_BG+PSA). When using biogas as fuel (Cases 2 and 3), these configurations were studied using air and oxy-fuel combustion atmospheres in the sorbent regeneration step, resulting in five case studies. A thermodynamic approach for process modeling can provide the optimal process operating conditions and configurations that maximize the energy efficiency of the process, which are the basis for subsequent optimization of the process at the practical level needed to scale up this technology. For this purpose, process simulations were performed using a steady-state plant model developed in Aspen Plus, incorporating a complex heat exchanger network (HEN) to optimize heat integration. A comprehensive parametric study assessed the effects of biogas composition, temperature, pressure, and steam to methane (S/CH4) ratio on the process performance represented by the selected key performance indicators, i.e., H2 purity, H2 yield, CH4 conversion, cold gas efficiency (CGE), net efficiency (NE), fuel consumption for the sorbent regeneration step, and CO2 capture efficiency. H2 with a purity of 98.5 vol % and a CGE of 75.7% with zero carbon emissions can be achieved. When adding a PSA unit, nearly 100% H2 purity and CO2 capture efficiency were achieved with a CGE of 77.3%. The use of oxy-fuel combustion during regeneration lowered the net efficiency of the process by 2.3% points (since it requires an air separation unit) but allowed the process to achieve negative carbon emissions.

In Europe, mainly due to industrial desulfurization, the supply of soil sulfur (S), an essential nutrient for crops, has been declining. One of the currently promoted sources of renewable energy is biogas production, which produces S as a waste product. In order to confirm the effect of the foliar application of waste elemental S in combination with liquid urea ammonium nitrate (UAN) fertilizer, a vegetation experiment was conducted with maize as the main crop grown for biogas production. The following treatments were included in the experiment: 1. Control (no fertilization), 2. UAN, 3. UANS1 (N:S ratio, 2:1), 4. UANS2 (1:1), 5. UANS3 (1:2). The application of UAN increased the N content in the plant and significantly affected the chlorophyll content (N-tester value). Despite the lower increase in nitrogen (N) content and uptake by the plant due to the application of UANS, these combinations had a significant effect on the quantum yield of PSII. The application of UANS significantly increased the S content of the plant. The increase in the weight of plants found on the treatment fertilized with UANS can be explained by the synergistic relationship between N and S, which contributed to the increase in crop nitrogen use efficiency. This study suggests that the foliar application of waste elemental S in combination with UAN at a 1:1 ratio could be an effective way to optimize the nutritional status of maize while reducing mineral fertilizer consumption.
