Abstract
In this work, the parameters of a hybrid cryogenic power plant using liquid hydrogen as a fuel are evaluated, and the characteristics of the main circuit of a hybrid power plant based on a piston expander, a rotor-blade expander, and a turbo expander are calculated. The parameters of the optimal scheme of the auxiliary circuit of the proposed power plant are calculated. The article presents the results of calculating the energy return coefficient and comparing the energy parameters of the designed systems. Energy plant of Rankine cycle auxiliary circuit using neon is shown to be the most effective in terms of their safety and cost-efficiency.

Keywords: hybrid power plant, piston expander, rotor-blade expander, turbo expander, energy return coefficient.
