Abstract: Systems and methods for a partial state condenser are described. In one embodiment, the partial state condenser receives a working fluid, and includes a sense reservoir that holds the working fluid, a reservoir sensor that senses an electrical property of the working fluid, and a reservoir valve that is in fluid communication with the sense reservoir. The partial state condenser yet further includes a processor configured to execute instructions to determine a specific energy of the working fluid based on the electrical property of the working fluid. The processor is also configured to execute instructions to control the reservoir valve to regulate a flow of a portion of the working fluid from the sense reservoir based on the specific energy of the working fluid to maintain a two-phase saturation state associated with a saturation point within the partial state condenser based on the electrical property.

Abstract: The present disclosure relates to systems and methods useful for power production. In particular, a power production cycle utilizing CO2 as a working fluid may be configured for simultaneous hydrogen production. Beneficially, substantially all carbon arising from combustion in power production and hydrogen production is captured in the form of carbon dioxide. Further, produced hydrogen (optionally mixed with nitrogen received from an air separation unit) can be input as fuel in a gas turbine combined cycle unit for additional power production therein without any atmospheric CO2 discharge.

Abstract: A system includes a combustion power plant for generating power and an electrolysis unit for producing hydrogen. The combustion power plant has a combustion chamber for combustion of a fuel and an offgas conduit for leading off hot offgases formed in the combustion of the fuel. The offgas conduit is thermally coupled to the electrolysis unit. A method for operating the system includes burning the fuel in the combustion power plant, forming the hot offgases in the combustion of the fuel, removing the hot offgases through the offgas conduit, feeding the thermal energy of the hot offgases from the offgas conduit to the electrolysis unit, and producing hydrogen in the electrolysis unit by using the thermal energy from the hot offgases.

Abstract: A gas turbine plant includes a gas turbine, an exhaust line, an exhaust heat recovery boiler that generates steam due to heat of exhaust gas and guides the exhaust gas to the exhaust line, a carbon dioxide recovery device that recovers carbon dioxide contained in the exhaust gas, a heat exchanger that cools the exhaust gas to a temperature set in advance, and a circulation line that branches from a position between the carbon dioxide recovery device and the heat exchanger and is connected to an inlet of the gas turbine. The carbon dioxide recovery device has an absorption tower that absorbs carbon dioxide contained in the exhaust gas by causing the exhaust gas at the set temperature and an absorption liquid to come into contact with each other. The heat exchanger is formed of a material having higher corrosion resistance than a material forming the exhaust heat recovery boiler.

Abstract: Solar/Rankine steam cycle hybrid concentrating solar power (CSP) systems and methods for designing or retrofitting existent natural circulation boilers using saturated or superheated steam produced by direct steam generation (DSG) or Heat Transfer Fluid (HTF) steam generators and CSP solar field technology systems are described. Additionally, methods and processes of retrofitting the existent Heat Recovery Steam Generators (HRSG) or biomass, gas, oil or coal fired boilers to operate integrated to a molten salt/water-steam heat exchangers are disclosed. The hybrid CSP systems are highly efficient due to the increase of steam generated by a heating section comprising either the DSG receiver or the molten salt-water-steam sequential heat exchangers, heaters, boiler/saturated steam generators, super-heaters and re-heaters. The additional saturated, superheated and reheated steam produced is directed to a Rankine cycle according to its pressure, temperature and steam quality significantly reducing the fuel consumption within a cogeneration or Combine Cycle Power Plant.

Abstract: Systems and methods for generating power using hydrogen fuel, such as derived from natural gas, are provided. Feed materials are introduced into a compact hydrogen generator to produce carbon dioxide, hydrogen gas and steam. Sorbent material within the compact hydrogen generator acts to absorb carbon dioxide, forming a used sorbent. Hydrogen gas and steam are separated from the used sorbent and passed to a power generator such as a hydrogen turbine to produce power. The used sorbent is introduced into a calciner and heated to desorb carbon dioxide and form a regenerated sorbent which can be recycled to the compact hydrogen generator.
