REFRIGERANTS
However, electrolysis should not be completely dismissed. Absorption also help buffer the intermittent output of renewable energy sources. Controllable, modern electric heaters, with integrated heat storage, can loss, avoiding the capital and operating costs of the electrolysis plant.
resulting carbonate solution generates a mixture of hydrogen and carbon of atmospheric CO2 by caustic potash (KOH) and electrolysis of the

This process is not just carbon neutral but carbon negative. Whether it is sequestered underground while the hydrogen can be fed to the gas grid.
