    Analysis of the Efficiency of Hydrogen Production Technology at Mini-CHP Plants Using Local Fuelsby Thermochemical Method by V. A. Sednin, R. S. Ignatovich

    Published 2023-08-01
    “…According to the results of the analysis of the mathematical model, it was determined that the specific consumption of electric energy per 1 kg of hydrogen for such a scheme will be 9.11 (kW×h)/kg, which is on average more than five times less than in the production of hydrogen by electrolysis, the rest of the required energy is replaced by thermal one, while the maximum fuel utilization factor of mini-CHP with a hydrogen production module using wood waste as fuel amounted to 83.1 %, including a thermal efficiency of 51.5 %, the efficiency of hydrogen production at the lowest calorific value is 31 %, the electrical efficiency for the supply of electricity to the grid is 0.6 %. …”

    Relationship between radon and oxygen diffusion coefficients in OPC concretes by P. Linares-Alemparte, M. Souto-Allaoui, C. Andrade-Perdrix

    Published 2025-08-01
    “…As concrete often forms the building envelope with the ground, it is interesting to investigate its performance as a barrier, i.e. its radon exhalation, which depends on the radon diffusion coefficient and thickness. Experimentally obtaining the radon diffusion coefficient in concrete is complicated, so it would be useful to be able to use an analytical method for its estimation from parameters that are easier to obtain, such as the oxygen diffusion coefficient, which can be determined experimentally with less difficulty and could even be estimated analytically. …”
