Definitions
- the invention relates to a device and a method for storing energy from combined heat and power plants which are operated with product gas from a carburetor of carbon-containing material, in particular wood, and to a synthesis gas mixture which results with the highest energy density, according to the preamble of claim 1 and claim 4 or claim 6.
- Such cogeneration plants use biogenic material, preferably wood, in a gas generator to produce product gas and, on the one hand, supply heat to households and businesses, possibly also to industrial companies, and via a gas engine, usually a piston engine (diesel or petrol engine), and a generator of electrical energy which is fed into a public or at least regional network.
- a gas engine usually a piston engine (diesel or petrol engine), and a generator of electrical energy which is fed into a public or at least regional network.
- the need for thermal energy is easy to estimate and only changes in a foreseeable way both daily and seasonally, the need for electrical energy, and with it the possibility of feeding it into the grid, changes in comparison to this in an unexpected manner and extremely quickly, what the Operating conditions at the gas generator does not meet, but, on the contrary, causes problems.
- the combined heat and power plant is assigned an electrolysis plant, preferably a hot electrolysis plant, in which water is split into hydrogen and oxygen when excess electricity occurs. Due to the heat generated during gas generation in the gas generator, which in one embodiment is led to the electrolysis system via a line for the heat transfer medium, for example heated air, the operation of this hot electrolysis system is possible with high efficiency at low costs.
- the hydrogen is stored, and preferably added to the synthesis gas in front of the engine of the combined heat and power plant when peak consumption occurs, which makes it possible to generate electricity in addition to the continuous output of the system and thus also to cover peak demand. This makes particular economic sense, which is directly evident from the price difference for the kilowatt hour of latitude and peak currents.
- the size of the memory can be adapted to the conditions of operation within wide limits and only makes technological demands that have already been solved in the prior art.
- the invention can be installed in existing systems, the possibility of coming above the nominal power is of course low, in new buildings a more powerful motor and generator than necessary for the gas generator alone can be built in, being aware of the seasonal and daily offers and inquiries for the person skilled in the field of combined heat and power plants or the energy industry, the determination of the possible delivery peaks with knowledge of the invention is not a problem.
- a typical composition of syngas from wood is as follows: component Percentage of space [vol .-%] Nitrogen, N 2 45 Carbon monoxide, CO 20-23.8 Hydrogen, H 2 17.01 -19.8 Carbon dioxide, CO 2 8.5 - 16.2 Methane, CH 4 1.5 - 2.9 Oxygen, O 2 0.4-0.6 Higher hydrocarbons, C m H n 0.2
- composition can be obtained by adding hydrogen: component Percentage of space [vol .-%] Nitrogen, N 2 35 Carbon monoxide, CO 21 Hydrogen, H 2 35 Carbon dioxide, CO 2 8th Methane, CH 4 1 Oxygen, O 2 0 Higher hydrocarbons, C m H n 0
- a further enrichment of hydrogen above 35% is not technologically sensible, since then thermal problems and problems with premature ignition of the mixture can occur on conventional engines.
- the enrichment of synthesis gas with a high proportion of CO from coal with hydrogen is, for example, from DE 33 34 687 known to be used as a starting material for methanol synthesis after removal of the sulfur.
- the invention therefore also relates to a gaseous fuel for diesel or gasoline engines, which consists of biogenic synthesis gas, to which hydrogen up to a total of 35 vol.% hydrogen content has been added.
