Turbine connected hybrid solar-syngas power system

A zero-emission closed-loop hybrid solar-syngas power cycle system, comprising:

• a solar reformer that converts methane to a syngas comprising CO and H2;
• a first oxygen transport reactor comprising a first ion transport membrane separating a first feed side and a first permeate side, the first feed side having a first feed inlet and a first feed outlet and the first permeate side having a first permeate inlet and a first permeate outlet,
• wherein H2O fed to the first feed inlet is converted into H2 gas on the first feed side and oxygen that passes across the first ion transport membrane to the first permeate side;
• and a first gas mixture comprising H2 and H2O is passed from the first feed outlet of the first oxygen transport reactor;
• a second oxygen transport reactor comprising a second ion transport membrane separating a second feed side and a second permeate side, the second feed side having a second feed inlet and a second feed outlet and the second permeate side having a second permeate inlet and a second permeate outlet,
• wherein CO2 gas fed to the second feed inlet is converted into CO gas on the second feed side and oxygen that passes across the second ion transport membrane to the second permeate side;
• and a second gas mixture comprising CO2 and CO is passed from the second feed outlet of the second oxygen transport reactor;
• a first condenser having a condenser inlet connected to the first feed outlet to separate the first gas mixture of H2 and H2O into H2O and H2 gas, a first condenser outlet connected to a H2 storage unit to deliver the H2 gas to the H2 storage unit, and a second condenser outlet connected to the first feed inlet to recycle the H2O into the first feed side of the first oxygen transport reactor;
• a CO separator having a separator inlet connected to the second feed outlet to separate the second gas mixture of CO2 and CO into CO and CO2, a first separator outlet connected to a CO storage unit to deliver the CO to the CO storage unit, and a second separator outlet connected to the second feed inlet to recycle the CO2 into the second feed side of the second oxygen transport reactor,
• wherein the H2 storage unit and the CO storage unit are connected to the first permeate inlet and to the second permeate inlet,
• wherein the CO storage unit stores CO produced from the second feed side of the second oxygen transport reactor during the day time and releases CO during the night time, and the H2 storage unit stores H2 produced from the first feed side of the first oxygen transport reactor during the day time and releases H2 gas during the night time,
• wherein the first oxygen transport reactor and the second oxygen transport reactor combust the syngas from the solar reformer, a syngas formed of H2 and CO from the H2 storage unit and the CO storage unit, or both in the presence of oxygen in the first permeate side and the second permeate side to form a first combustion gas mixture comprising water vapor and CO2 gas,
• wherein the CO gas from the CO storage unit is contacted with H2 gas from the H2 storage unit to form the syngas used as an input gas into the first permeate side of the first oxygen transport reactor and the second permeate side of the second oxygen transport reactor during the night time,
• a gas turbine connected to the first permeate outlet to produce power from the first combustion gas mixture, wherein the gas turbine has a turbine outlet connected to a second condenser that separates the first combustion gas mixture into H2O and CO2, wherein a first outlet of the second condenser is connected to the first feed inlet to feed the H2O to the first oxygen transport reactor and a second outlet of the second condenser is connected to a first compressor at least partially driven by energy from the gas turbine to feed compressed CO2 to the second feed inlet to feed the CO2 to the second oxygen transport reactor.
