This work was prepared as part of the scientific internship of Jacek Caban at the Institute
of Mechanical Science of Vilnius Gediminas Technical University which took place from 26 July to
6 August 2021.
This article presents a 3D model of a yellow hydrogen generation system that uses the
electricity produced by a photovoltaic carport. The 3D models of all key system components were
collected, and their characteristics were described. Based on the design of the 3D model of the
photovoltaic carport, the amount of energy produced monthly was determined. These quantities
were then applied to determine the production of low-emission hydrogen. In order to increase
the amount of low-emission hydrogen produced, the usage of a stationary energy storage facility
was proposed. The Metalog family of probability distributions was adopted to develop a strategic
model for low-emission hydrogen production. The hydrogen economy of a company that uses small
amounts of hydrogen can be based on such a model. The 3D modeling and calculations show that it
is possible to design a compact low-emission hydrogen generation system using rapid prototyping
tools, including the photovoltaic carport with an electrolyzer placed in the container and an energy
storage facility. This is an effective solution for the climate and energy transition of companies
with low hydrogen demand. In the analytical part, the Metalog probability distribution family was
employed to determine the amount of monthly energy produced by 6.3 kWp photovoltaic systems
located in two European countries: Poland and Italy. Calculating the probability of producing specific
amounts of hydrogen in two European countries is an answer to a frequently asked question: In
which European countries will the production of low-emission hydrogen from photovoltaic systems
be the most profitable? As a result of the calculations, for the analyzed year 2023 in Poland and Italy,
specific answers were obtained regarding the probability of monthly energy generation and monthly
hydrogen production. Many companies from Poland and Italy are taking part in the European
competition to create hydrogen banks. Only those that offer low-emission hydrogen at the lowest
prices will receive EU funding.
