A unique complex allowing to convert hydrogen into electricity was developed at the Nizhny Novgorod State Technical University (NSTU) named after R.E. Alekseev. The complex consists mainly of domestic components and has its own software created by Nizhny Novgorod scientists. At the same time, the complex is equipped with an operational safety system that will minimize the likelihood of accidents at hydrogen power plants of autonomous facilities.
"The key feature of the project is the development of an electric power parameter converter and a control system that ensures the efficient use of hydrogen fuel and reliable power supply to consumers. By the end of 2022, we will complete the development of an experimental sample of a hybrid energy complex based on a low-temperature fuel cell and lithium-iron-phosphate batteries, which will create a scientific and technical foundation for the transition to the implementation of projects with high—capacity hydrogen power plants," said Sergey Dmitriev, Rector of the R.E. Alekseev NSTU.
The use of hydrogen in comparison with traditional fuels is more environmentally friendly. Hydrogen energy sources are characterized by the absence of noise, harmful emissions, and only water is released as a by-product. Hydrogen-based power generating complexes can be used at autonomous facilities, for example, at gas and oil industry facilities, railway transport and many others. Hydrogen energy is necessary in the transition to a carbon-free economy of the country.
"Hydrogen is the most common substance on Earth, which has a very high energy. We are engaged in generating electricity from hydrogen. When obtaining energy by conventional methods, only 30-35% of electrical energy comes out of 100%, the rest is released as heat and losses. The converters that we are working on within the framework of this project make the conversion of hydrogen more efficient. At our stand, we have already reached 40-45%, which is higher than at existing power plants," said Alexey Loskutov, Professor of the Department of Electric Power Engineering, Power Supply and Power Electronics of the Educational and Scientific Institute of Electric Power Engineering of the R.E. Alekseev NSTU.
The work is carried out within the framework of the strategic project of the university "Cybersecurity devices and technologies of electric power systems" according to the program of the Ministry of Education and Science of Russia "Priority 2030" (national project "Science and Universities"), as well as with the support of industrial partners and enterprises of domestic industry. Upon completion of the work, the electric generating complex will be implemented at one of the industrial enterprises of the oil and gas complex of Russia.
At the same time, an experimental model of an operational safety system for a hydrogen power plant is being developed at the university. The results of the development will be a set of technical solutions and a control system that ensures the safety of consumers when using a hydrogen power plant. The solutions obtained will be used to create a prototype of an autonomous hydrogen-powered power source next year.
