1. A system, comprising:
a combustion power plant for generating power and an electrolyzer for producing hydrogen;
said combustion power plant having a combustion chamber for combustion of a fuel and an offgas conduit for leading off hot offgases formed in the combustion of the fuel;
said offgas conduit being thermally coupled to said electrolyzer;
an open-loop controller configured to control a rate of heat transfer from said offgas conduit to said electrolyzer; and
a closed-loop controller configured to compensate for any fluctuation in an operating temperature of said electrolyzer resulting from a fluctuation in a power supplied to said electrolyzer by control exerted by said open-loop controller.
