In recent years, newfound interest in the hydrogen economy from both industry and academia has helped to shed light on its potential. Hydrogen can enable an energy revolution by providing much needed flexibility in renewable energy systems. As a clean energy carrier, hydrogen offers a range of benefits for simultaneously decarbonising the transport, residential, commercial and industrial sectors. Hydrogen is shown here to have synergies with other low carbon alternatives, and can enable a more cost-effective transition to de-carbonised and cleaner energy systems. This paper presents the opportunities for the use of hydrogen in key sectors of the economy and identifies the benefits and challenges within the hydrogen supply chain for power-to-gas, power-to-power and gas-to-gas supply pathways. While industry players have already started market introduction of hydrogen fuel cell systems, including fuel cell electric vehicles and micro-combined heat and power devices, the use of hydrogen at grid-scale requires the challenges of clean hydrogen production, bulk storage, and distribution to be resolved. Ultimately, greater government support, in partnership with industry and academia, is still needed to realise hydrogen's potential across all economic sectors.

“…In this scenario, the development of sustainable H 2 production technologies plays a significant role [1][2][3], with a special interest in the routes from lignocellulosic biomass [4,5] due to its high availability and whose valorisation does not interfere in the feeding chain. Among these routes from biomass, great attention is paid to the H 2 production by steam reforming (SR) of bio-oil, the liquid product from the pyrolysis of lignocellulosic biomass [6][7][8].…”

“…The SR of bio-oil is a highly endothermic reaction [6,8,14] that follows the general stoichiometry of oxygenates reforming, Equation (1), and considering the water gas shift reaction, Equation (2), the complete stoichiometry of this overall reaction is given by Equation (3). …”

Oxidative Steam Reforming of Raw Bio-Oil over Supported and Bulk Ni Catalysts for Hydrogen Production

et al. 2018

Several Ni catalysts of supported (on La 2 O 3 -αAl 2 O 3 , CeO 2 , and CeO 2 -ZrO 2 ) or bulk types (Ni-La perovskites and NiAl 2 O 4 spinel) have been tested in the oxidative steam reforming (OSR) of raw bio-oil, and special attention has been paid to the catalysts' regenerability by means of studies on reaction-regeneration cycles. The experimental set-up consists of two units in series, for the separation of pyrolytic lignin in the first step (at 500 • C) and the on line OSR of the remaining oxygenates in a fluidized bed reactor at 700 • C. The spent catalysts have been characterized by N 2 adsorption-desorption, X-ray diffraction and temperature programmed reduction, and temperature programmed oxidation (TPO). The results reveal that among the supported catalysts, the best balance between activity-H 2 selectivity-stability corresponds to Ni/La 2 O 3 -αAl 2 O 3 , due to its smaller Ni 0 particle size. Additionally, it is more selective to H 2 than perovskite catalysts and more stable than both perovskites and the spinel catalyst. However, the activity of the bulk NiAl 2 O 4 spinel catalyst can be completely recovered after regeneration by coke combustion at 850 • C because the spinel structure is completely recovered, which facilitates the dispersion of Ni in the reduction step prior to reaction. Consequently, this catalyst is suitable for the OSR at a higher scale in reaction-regeneration cycles.

“…For example, Czyrnek‐Delêtre et al () focus on the effects of indirect land use on the expansion of biomass and bioenergy used in the industry, transport and electricity, in the context of mitigation policies. Other authors, such as Sgobbi et al () study the introduction of alternative sources of energy such as hydrogen, in the energy matrix, again, without particular interest in one or another sector. Other typical application of energy models for the overall economy, as in Jia et al () for China, is the analysis of energy demand in the economy as a whole.…”

This study analyzes 34 tools through 442 publications on energy systems modeling, aiming to identify the most relevant trends in research and the research gaps in energy planning. For detecting these gaps, the publications analyzed were categorized based on pre-defined criteria regarding geographical coverage, sectoral coverage, time horizon, analytical approach and energy source. The categories were designed to be a broad classification with the appropriate level of information required to differentiate between models. The results show that there is a lack of studies concerned with better understanding the energy systems in Africa and South America. Environmentally-oriented publications account for 50.4% of all the publications studied. Modelers have thus shown a greater interest in studying issues related to climate change mitigation than in other areas of the energy chain.
