摘要:
There are described thermoelectric elements that are manufactured by using a porous matrix or a porous substrate. The matrix consists of an electrically insulating material having sufficient thermal and chemical resistance as well as the lowest possible thermal conductivity, and is provided in predetermined regions with different thermoelectric materials, so that continuous conductors are formed in the matrix. These are electrically connected to one another to form thermocouples, which in turn are electrically interconnected with one another to form the thermoelectric element.

The present invention relates to an integrated plant which comprises a plant for the electrothermic production of ethyne and a plant for electricity generation, the plant for the electrothermic production of ethyne being connected to the plant for electricity generation via a conduit and electricity being generated in the plant for electricity generation from a product gas obtained in the plant for the electrothermic production of ethyne. This integrated plant affords flexible use of electricity by a method in which, at times of a high electricity supply, the plant for the electrothermic production of ethyne is operated and at least some of the hydrogen and/or gaseous hydrocarbons obtained in addition to ethyne is stored and, at times of a low electricity supply, stored hydrogen and/or gaseous hydrocarbons are fed to the plant for electricity generation.

摘要:
A method for providing control power for an electricity network in which at least one energy store connected to the electricity network supplies energy to the electricity network as required and/or takes up energy from the electricity network as required, the control power being delivered in dependence on a frequency deviation from a setpoint value of a network frequency, a tolerance with respect to the frequency deviation being used to set a charging state of the energy store at a same time as providing the control power by the energy store. A device for carrying out such a method includes a control system and an energy store, the device being connected or connectable to an electricity network, the control system being connected to the energy store and controlling the control power that is given off and/or taken up by the energy store.
