The desire to reduce pollution and price instability generated by the major share of fossil fuel use requires firm solutions for green transition of economy, that must provide access to clean, safe and affordable energy. An important sector, seriously affected, being a competitive field with consistent limitations, is the transport system, where use of alternative fuels, the hydrogen, is perhaps a solution. Hydrogen can be used as a raw material, fuel, and can be stored with many other possible uses in industry sectors, not only transportation. Most importantly, it does not emit CO2 and almost does not pollute the air when in use. It therefore provides a solution for decarbonising industrial processes and economic sectors where carbon reduction is both urgent and difficult to achieve. All this makes hydrogen essential to support the EU's commitment to climate neutrality, on the one hand, and to global effort to implement the Paris Agreement, on the other. The present paper presents all aspects, through simulation in MATLAB-Simulink, of the production, storage and use of hydrogen as an alternative fuel source.

“…Hydrogen is a renewable energy source in Indonesia with various applications, including as feedstock for chemical production, transportation fuel, and energy sources for power plants (Al-Fatesh et al, 2023;Erbach and Jensen, 2021;Grecea et al, 2021;Sampaio et al, 2022). It can be produced from organic materials such as agricultural waste through various transformation procedures (Borgogna et al, 2022;Chari et al, 2023;Li et al, 2010;Łukajtis et al, 2018;Megia et al, 2021;Ozturk and Dincer, 2021).…”

Hydrogen production from agricultural waste is a potentially established industry in Indonesia, and the government aims to introduce innovative technologies to produce hydrogen. This study aimed to explore the feasibility of hydrogen production from agricultural waste using three different methods: SCWG, fermentation, and gasification. The analysis focuses on comparing the price of hydrogen as a product by setting the same value of the IRR at 30%. The simulation was conducted by analyzing the capacity of hydrogen production at 3650 tons/year. The results of this study demonstrate that fermentation is the most feasible technology for producing hydrogen from agricultural wastes in Indonesia. In this technology, the price of hydrogen obtained was $5.65/kg, with a total capital investment (TCI) and production cost (TPC) of $10,756,132.97 and $13,977,351.97, respectively. Based on this simulation, the other parameter values, including NPV, ROI, and PoT, were $15,387,688.72, 68%, and 2.27 years, respectively. These results indicate that the establishment of hydrogen production in Indonesia using fermentation technology and agricultural waste is economically viable.

“…The transport sector tops this list and is one of the most difficult to decarbonise. Projections show that the amount of GHG reduction needed in the transportation industry between 2020 and 2030 is approximately 40 percent, 80 percent by 2050 [6]. Expecting an increase in transportation demand in the coming years, emission reductions / vehicle will should grow even more.…”

Currently, the burning of fossil fuels in industry or for transportation has a major negative impact on the environment. Most countries are concerned with environmental security and pollution regulation, motivating researchers around the world to find alternative solutions. An alternative solution may be the large-scale use of hydrogen. Applications of hydrogen in industry or for transportation face challenging conditions. Among other things, we are talking about pressures of up to 1000 bar, extreme temperatures starting from -253 °C (for liquefied hydrogen) and up to 650 °C - 950 °C (in the case of solid oxide electrolytic cells), as well as the imminent risk of explosion. This is because H2 has an extremely low ignition energy, with much wider flammability limits compared to other fuels such as methane or propane. Hydrogen is a highly reactive and explosive gas. Therefore, explosion protection is essential for all processes involving the use of hydrogen in one form or another. The same principles that are applied to natural gas can be applied. Hydrogen behaves similarly to methane in terms of explosion risk, meaning in principle that explosion protection works similarly for both gases. However, there are still many unknowns regarding the phenomenon of initiation and propagation of explosions caused by air-hydrogen mixtures. Taking into account the multiple aspects related to security techniques that must be taken into account for the use of hydrogen in industry or for transport, the current paper focuses on aspects with regard to the use of modern numerical modelling tools for increasing the occupational health and safety level in technological processes endangered by the occurrence of explosive atmospheres generated by air-hydrogen mixtures. It presents a review on the main research activities to be carried out within a the H2Model research project implemented between 2023 – 2026, project which focuses on numerical modelling on the ignition and propagation of explosions caused by air-hydrogen mixtures.
