TL;DR: In this article, a semi-submersible hull with ballast weight that is moveable to increase the system's stability is used to support a wind energy conversion system optimized for offshore application.
Abstract: A wind energy conversion system optimized for offshore application. Each wind turbine includes a semi-submersible hull with ballast weight that is moveable to increase the system's stability. Each wind turbine has an array of rotors distributed on a tower to distribute weight and loads and to improve power production performance where windshear is high. As much of the equipment associated with each rotor as possible is located at the base of the tower to lower the metacentric height. The equipment that may be emplaced at the bottom of the tower could include a power electronic converter, a DC to AC converter, or the entire generator with a mechanical linkage transmitting power from each rotor to the base of the tower. Rather than transmitting electrical power back to shore, it is contemplated to create energy intensive hydrogen-based products at the base of the wind turbine. Alternatively, there could be a central factory ship that utilizes the power produced by a plurality of wind turbines to create a hydrogen-based fuel. The hydrogen-based fuel is transported to land and sold into existing markets as a value-added 'green' product.

TL;DR: In this paper, a method for removing and recovering CO2 from exhaust gas from a gas turbine based electric power and heat generation process (a main power process) by chemical absorption and description for deposition of CO2 as convenient at the location.
Abstract: The present invention relates to a method for removing and recovering CO2 from exhaust gas from a gas turbine based electric power and heat generation process (a main power process) by chemical absorption and description for deposition of CO2 as convenient at the location. The exhaust gas from said main power process is cooled before being fed to a secondary gas turbine based power and heat generation process (a secondary power process) where said exhaust gas is compressed to elevated pressure and used as oxidant in a secondary gas turbine combustion chamber in said secondary power process. The resulting hot exhaust gas from said secondary process is further fed to a turbine connected to an electric power generator where the exhaust gas is depressurised to close to ambient pressure before entering a heat recovery process where the exhaust gas is cooled and further fed to a CO2 separation process for capturing of CO2.
