During several recent years an increasing interest concerning behavior of various gaseous or liquid hydrocarbons mixtures with neat gaseous hydrogen is observed. The phase equilibria as well as flow properties have been studied and some practical implementations indicated. The main practical idea consists in a possibility to use such mixtures as a replacement for pure hydrocarbons actually used as the energy source. Application of hydrogen enriched mixtures seem to be a temporary solution for gradual decarbonization of energy resources. The advantage of such approach may consist in much smaller requirements for investment in various aspect of infrastructure needed for handling the fuels. The present work is devoted to computer simulation of carbon dioxide emissions for several scenarios based on different compositions of hydrogen mixtures with hydrocarbons. The simulations include estimation of calorific value of the mixture and composition of exhaust gases emitted after its combustion. The simulation, based on s.c. logistic function, evaluates several variants of time dependence of new fuels implementation, and consequently time dependence of changes in composition of emissions to atmosphere. The simulation can be used for choosing the ways of practical implementation management.

“…In recent years, the widespread adoption of hydrogen energy worldwide has precipitated the global energy transformation and advanced the implementation of various low-carbon policies (Drela, 2021;Hassan et al, 2024). This clean energy source boasts diverse origins, a high calorific value, and non-polluting combustion products (Chavda et al, 2022), making it a promising candidate to replace fossil fuels in the 21st century.…”

Nuclear hydrogen production has the advantages of large-scale and low carbon emissions, and is expected to play an active role in the energy transition process. However, the storage and transportation of hydrogen pose potential risks of leakage and diffusion when connected to high-pressure hydrogen storage tanks and pipelines. To address this concern, this study focused on designing three distinct safety improvement schemes tailored for potential hydrogen leakage accidents. These schemes encompassed a passively distributed arrangement of obstacles (Scheme 1), a passively centralized arrangement of obstacles (Scheme 2), and an active fan array blowing (Scheme 3). Numerical simulation methods were applied on extensive spatial scales for relevant calculations. The results revealed that all three schemes effectively reduced the diffusion distance of combustible hydrogen. Specifically, at lower ambient wind speeds, Scheme 1, Scheme 2, and Scheme 3 achieved the shortest diffusion distances of 123 m, 56 m, and 46 m, respectively. Meanwhile, at higher ambient wind speeds, the corresponding distances were 282 m, 100 m, and 79 m. These results collectively offer valuable insights to mitigate the risk of leakage accidents in nuclear hydrogen production systems.
