Devices, systems and methods for improved hydrogen manufacture, processing, and shipping using solar derived power. A system for manufacturing hydrogen gas uses a solar power generator, an electrolyzer powered by the solar power generator, a gas separator for separating gases generated by the electrolyzer, such as oxygen and hydrogen, and a gas compressor for compressing the gases for transport and later use. The solar power generator may be one or more PV arrays and may further be at least one earth mount PV assembly. The PV assemblies may connect in parallel or in series. The electrolyzer comprises at least two distributed electrolyzer stacks. A system for manufacturing hydrogen and using the hydrogen gas may use a solar power generator, an oxyhydrogen electrolyzer powered by the solar power generator, and an oxyhydrogen boiler that generates steam for generating electrical power.

A method and system enabling the efficient use of thermal energy to provide kinetic energy and/or electrical energy. The method uses at least two heat exchangers for heating the working medium, a heat engine and a condenser. The working medium consists of at least two substances. The working medium is partially condensed on the primary side of the first heat exchanger, wherein heat is transferred to the working medium flowing on the secondary side and, subsequently, further condensation heat is transferred to a cooling circuit in a condensation heat exchanger on the primary side of the condensation heat exchanger. Subsequently, the working medium is redirected to the secondary side of the first heat exchanger. A separation of gaseous fractions of the working medium takes place in the condensation heat exchanger on the primary side.

A heat cycle system includes a cooling circuit and a Rankine cycle circuit in which an organic medium circulates. The Rankine cycle circuit includes an evaporator, an expander, and a condenser. Before warm-up of an engine, a control device executes a warm-up mode in which the organic medium is circulated through the condenser, the expander and the evaporator in sequence; after the warm-up of the engine, the control device executes a waste heat recovery mode in which the organic medium is circulated through the evaporator, the expander and the condenser in sequence. In the warm-up mode, by supplying energy to the expander, the control device compresses the organic medium passing through the condenser and supplies the compressed organic medium to the evaporator; in the waste heat recovery mode, by depressurizing the organic medium passing through the evaporator by the expander, the control device recovers the energy generated by the expander.
