“…First of all, from the point of view of the amount of energy produced, there is an increase in the electrical and thermal power of the plant of 1.8 MW and 2 MW respectively. Other research works analyzed the thermodynamic and environmental impacts of heat and power production from residual biomass gasification with a Life Cycle approach [17], showing the beneficial effects of integrating the gasification-CHP system with the fruit juice industry.…”

Bio-hydrogen from sustainable biomass (i.e. agro-industrial residues) gasification can play a relevant role in the hydrogen economy, providing constant hydrogen from renewable sources. Nowadays, most hydrogen production systems integrate one or more water-gas shift (WGS) units to maximize the hydrogen yield that, however, needs additional syngas treatments, investment and operational costs. Besides, different electricity inputs are needed along the process to power the compression of raw syngas, shifted syngas, and pure hydrogen to the desired pressure. This common process integration with WGS generates a kind of off-gas from the hydrogen separation unit whose composition may or may not be suitable for power production, depending on the operating conditions of the gasification unit. In this regard, this work proposes a different approach in which no WGS reactors are involved and the off-gas is used to generate heat and power to provide the energy input needed by the system. In particular, the authors tested the bio-syngas and the corresponding off-gas in a 4-cylinders, spark ignition natural gas internal combustion engine operated in cogeneration mode with the aim to analyse the effect of removing the hydrogen from the original bio-syngas on mechanical/electric and thermal power, on fuel efficiency and CO2 specific emission.

“…Via process simulation, they demonstrated that proper thermal integration and plant size could reduce the carbon impacts of the citrus juice industry. In addition, the Life Cycle Assessment (LCA) of citrus peel-based gasification-CHP demonstrated the thermodynamic and environmental advantages of this integration with the juice industry compared to the reference scenarios [6].…”

“…The impacts of process parameters on the system's yields, efficiencies, and renewability degree are assessed by sensitivity analysis. The thermodynamic performance is based on exergy data, while the renewability degree of bio-hydrogen is evaluated by the "Integrated Renewability" indicator, recently introduced by Prestipino et al [6]. The proposed configuration's advantage relies on the possibility of cogenerating, along with hydrogen, electricity, and heat that can be exploited to cover the process heat and power demand.…”

Bio-hydrogen from residual biomass may involve energy-intensive pre-treatments for drying and size management, as in the case of wet agro-industrial residues. This work assesses the performance of an alternative process layout for bio-hydrogen production from citrus peel gasification, with the aim of cogenerating heat and power along with hydrogen, using minimal external energy sources. The process consists of an air-steam fluidized bed reactor, a hydrogen separation unit, a hydrogen compression unit, and a combined heat and power unit fed by the off-gas of the separation unit. Process simulations were carried out to perform sensitivity analyses to understand the variation in bio-hydrogen production’s thermodynamic and environmental performance when the steam to biomass ratios (S/B) vary from 0 to 1.25 at 850 °C. In addition, energy and exergy efficiencies and the integrated renewability (IR) of bio-hydrogen production are evaluated. As main results, the analysis showed that the highest hydrogen yield is 40.1 kgH2 per mass of dry biomass at S/B = 1.25. Under these conditions, the exergy efficiency of the polygeneration system is 33%, the IR is 0.99, and the carbon footprint is −1.9 kgCO2-eq/kgH2. Negative carbon emissions and high values of the IR are observed due to the substitution of non-renewable resources operated by the cogenerated streams. The proposed system demonstrated for the first time the potential of bio-hydrogen production from citrus peel and the effects of steam flow variation on thermodynamic performance. Furthermore, the authors demonstrated how bio-hydrogen could be produced with minimal external energy input while cogenerating net heat and power by exploiting the off-gas in a cogeneration unit.

“…Its lower calorific power (LHV) usually varies between 9 to 13.5 MJ/kg [7]. Typically, when processing thermochemical biomass, three types of products are obtained [8]: liquid-phase bio-oils with high content of oxygenated compounds [9,10,11], [12] synthesis gas usually composed of hydrogen, carbon monoxide and traces of other elements such as methane, carbon dioxide, and some volatile compounds [13], and organic charcoal with concentrated oxidising organic carbon and acetyl compounds that give it a particular smell [14].…”

The transformation and use of agricultural and agro-industrial biomass has been the focus of study in recent years, due to its treatment and use in value-added products such as liquid, solid and gaseous fuels. Molecules such as hydrogen, organic carbon, organic nitrogen, oxygen, and oxygenated compounds present in the liquid phase of biomass currently represent opportunities for synthesis of green fuels and inputs for the industry. In this work was discussed the main aspects for Animal Biomass transformations from a perspective based on Biooils composition obtained from different thermochemical methods, containing model molecules, useful for biofuels synthesis for transportation.
