The invention relates to a grid-connected power plant, having the following systems which are adjusted in their capacitance to each other: a) a wind power plant, water power plant, solar-thermal system and/or photovoltaic system for the production of electrical energy for operating the systems b) through f); b) a CO2 absorption system for the absorption of atmospheric CO2; c) a CO2 desorption system for the desorption of the CO2 gained in b); d) an electrochemical or solar-thermal H2 synthesis system for the operating system e); e) a synthesis system selected from the group catalytic methanol synthesis, catalytic DME synthesis, catalytic methane synthesis; f) a storage system selected from the group methanol storage system, DME storage system, methane storage system. The invention also relates to the use of such a power plant and methods for the operation of such a power plant.
A power plant, not connected to the grid, which is characterized in that it contains the following installations, the capacities of which are matched to one another:
The power plant of one of the preceding claims, not connected to the grid, characterized in that the air current in the CO2 absorption installation optionally is moistened initially and then bought into contact countercurrently with alkaline washing liquor.
The power plant of one of the preceding claims, not connected to the grid, characterized in that the rotor blades and/or the masts of the wind power installation a) are provided with a hydrophobic, microporous membrane for CO2 absorption, particularly wherein the hydrophobic microporous membranes are covered with a hygroscopic material.
The power plant of one of the preceding claims, not connected to the grid, characterized in that the CO2 desorption installation b) operates according to the principle of acidification, optionally with subsequent electrodialysis.
The power plant of one of the preceding claims, not connected to the grid, characterized in that the electrochemical hydrogen synthesis installation c) operates according to the principle of high-temperature electrolysis of water, which optionally is desalinated.
The power plant of one of the preceding claims, not connected to the grid, characterized in that the catalytic synthesis installation d) is either
The power plant of one of the preceding claims, not connected to the grid, characterized in that the CO2 desorption installation c) produces carbon monoxide under reductive conditions from carbonate used and that the methanol synthesis installation e) is a methanol/synthesis gas installation.
The power plant of one of the preceding claims, not connected to the grid, characterized in that the CO2 absorption installation contains a wet chemical CO2 absorption installation containing a washing liquor, wherein the washing liquor preferably contains a component, which reduces evaporation.
The power plant of one of the preceding claims, not connected to the grid, characterized in that the CO2 absorption installation is a dry chemical CO2 absorption installation and the CO2 desorption installation is a dry chemical CO2 desorption installation, wherein preferably the desorption is carried out in the presence of superimposed hydrogen.
