“…This demand has been covered by grey hydrogen produced from fossil fuels, which corresponds to carbon emissions of 200 MtCO 2 [68]. Replacing grey hydrogen with green hydrogen in oil refining has the potential to reduce the emissions resulting from this sector by 22% [69]. Hence, adequate consideration must be given to promoting the utilization of green hydrogen in crude oil refining.…”

Green hydrogen and power-to-X technologies hold significant potential in the global energy transition towards net-zero emissions. This is attributed to the premise that these technologies can decarbonize numerous sectors worldwide by providing versatile and sustainable energy carriers and industrial feedstocks to replace fossil-based fuels and chemicals. To this end, the qualitative benefits of green hydrogen and power-to-X technologies have been thoroughly examined for various applications in past years. In contrast, quantifying the potential penetration of such technologies on national and global levels still requires extensive research. Therefore, this paper investigates the prospective integration of green hydrogen and power-to-X technologies within Jordanian industries, considering their quantitative utilization potential for current and future capacities. The findings showed that the Jordanian food processing and heavy industries emerged as major sectors with substantial potential for incorporating green hydrogen and power-to-X products as alternative fuels or chemical feedstocks. In detail, the total potential utilization capacity for these sectors stood at around 57 thousand tons per year. Specifically, fertilizers production, cement industry, steel reforming, and oil refinery possess an annual potential capacity of around 6.8, 11.8, 12.7, and 25.8 thousand tons, respectively. It is also worth mentioning that the current utilization capacity of hydrogen in Jordanian industries was found to be around 8.9 thousand tons per annum, which is completely covered by fossil-based hydrogen to date. These results imply that there will be a promising market for green hydrogen and power-to-X utilization in Jordanian industries, which will play a significant role in integrated energy transition efforts in the future.

“…A common theme in the literature is that the cost of electrolysis is the main economic limiting factor when considering hydrogen as a sustainably derived energy vector [214,227]. Storage has been posited as a means through which to make better use of existing electrolysis capacity without the installation of further electrolysis apparatus, especially when that hydrogen can be stored in major geological features such as salt caves [227]. In some European countries, the hydrogen capacity in such formations exceeds 10 EJ of hydrogen [214].…”

Intensification of Acidogenic Fermentation for the Production of Biohydrogen and Volatile Fatty Acids—A Perspective

Utilising ‘wastes’ as ‘resources’ is key to a circular economy. While there are multiple routes to waste valorisation, anaerobic digestion (AD)—a biochemical means to breakdown organic wastes in the absence of oxygen—is favoured due to its capacity to handle a variety of feedstocks. Traditional AD focuses on the production of biogas and fertiliser as products; however, such low-value products combined with longer residence times and slow kinetics have paved the way to explore alternative product platforms. The intermediate steps in conventional AD—acidogenesis and acetogenesis—have the capability to produce biohydrogen and volatile fatty acids (VFA) which are gaining increased attention due to the higher energy density (than biogas) and higher market value, respectively. This review hence focusses specifically on the production of biohydrogen and VFAs from organic wastes. With the revived interest in these products, a critical analysis of recent literature is needed to establish the current status. Therefore, intensification strategies in this area involving three main streams: substrate pre-treatment, digestion parameters and product recovery are discussed in detail based on literature reported in the last decade. The techno-economic aspects and future pointers are clearly highlighted to drive research forward in relevant areas.

“…Shi et al coupled high-purity hydrogen produced from wind and solar energy with the coalto-ethylene glycol process, enhancing ethylene glycol yields and significantly reducing product carbon footprints [34]. Nascimento da Silva et al harnessed surplus wind energy to produce hydrogen for the hydrogenation units of petroleum refineries, replacing steam methane reforming for hydrogen production and enabling oxygen supply for oxygen combustion carbon dioxide capture in fluid catalytic cracking (FCC) units [35]. This process can reduce greenhouse gas emissions from refineries by up to 22.11%.…”

The refining industry is shifting from decarbonization to hydrogenation for processing heavy fractions to reduce pollution and improve efficiency. However, the carbon footprint of hydrogen production presents significant environmental challenges. This study couples refinery linear programming models with life cycle assessment to evaluate, from a long-term perspective, the role of low-carbon hydrogen in promoting sustainable and profitable hydrogenation refining practices. Eight hydrogen-production pathways were examined, including those based on fossil fuels and renewable energy, providing hydrogen for three representative refineries adopting hydrogenation, decarbonization, and co-processing routes. Learning curves were used to predict future hydrogen cost trends. Currently, hydrogenation refineries using fossil fuels benefit from significant cost advantages in hydrogen production, demonstrating optimal economic performance. However, in the long term, with increasing carbon taxes, hydrogenation routes will be affected by the high carbon emissions associated with fossil-based hydrogen, losing economic advantages compared to decarbonization pathways. With increasing installed capacity and technological advancements, low-carbon hydrogen is anticipated to reach cost parity with fossil-based hydrogen before 2060. Coupling renewable hydrogen is expected to yield the most significant economic advantages for hydrogenation refineries in the long term. Renewable hydrogen drives the transition of refining processing routes from a decarbonization-oriented approach to a hydrogenation-oriented paradigm, resulting in cleaner refining processes and enhanced competitiveness under emission-reduction pressures.
