- Fig. 1 shows an overview of the systematic classification of the exemplary system 1000 in the supply structure of a building 2000/2100 or the systems and machines of a building 2000/2100 and the energy suppliers 40/45.
- the exemplary system 1000 is, as shown in illustration b), connected between the energy suppliers 40/45 and the building 2000/2100 as a consumer.
- a primary load-dependent energy converter such as a computing unit or a data center in the exemplary system 1000 can be used to generate the heat in the building 2000/2100 (through consumption/ Conversion of electrical energy E into thermal energy T through calculation processes), whereby, for example, the supply of the building 2000/2100 with natural gas by a natural gas supplier 45 can be omitted (typically natural gas is used for heating the building 2000/2100, in some cases also for cooking in building 2000/2100).
- the burning of fossil fuels can be largely avoided.
- the primary load dependence can, for example, lead to a fluctuation in the generation of heat for the building 2000/2100
- the exemplary system 1000 is explained in more detail below in FIG. 2. 2 shows an exemplary embodiment of the exemplary system 1000 for the continuous, needs-based energy supply of a building 2000 (for a more detailed view of the building, see FIG. 3) using a first, primary load-dependent energy converter 210 of a first energy converter module 200.
- these devices convert at least some of the form of energy required for value creation (first, second, third form of energy) into another form of energy (first, second, third form of energy).
- first, second, third form of energy For example, part of an electrical energy E (for example, first form of energy), which the device requires, for example, to process a workpiece or to carry out arithmetic operations, can be converted, for example, into thermal energy T (for example, second form of energy).
- thermal energy T for example, second form of energy
- This amount of energy converted into heat (thermal energy T) could be advantageously used for other purposes (such as heating private and/or office buildings, heating agricultural facilities such as stables, etc.).
- Such production processes or the use of servers/computing units are often subject to corresponding, sometimes large, fluctuations.
- the machine tool which is not processing a component due to maintenance/setup, cannot generate any usable waste heat or the computing unit can hardly be used if it is not used enough Generate waste heat.
- This form of generation/conversion of the thermal energy T is therefore subject to fluctuations in the utilization/the extent of the primary load of the devices, so that a continuous supply of the buildings/facilities with thermal energy T can hardly be guaranteed.
- the interaction of various components, sometimes also differently designed components (units, modules) of the exemplary system 1000 will be explained using the exemplary system 1000, with further positive effects being explained depending on the combination and expansion of the exemplary system 1000.
- electrical energy E for example first form of energy
- this electrical energy E or at least part of this electrical energy E (or the amount of energy of the electrical energy E) can be converted, for example, into thermal energy T (for example second form of energy) by the first, Primary load-dependent energy converter 210 of the first energy converter module 200 can be done advantageously.
- a high level of efficiency comparable to the high levels of efficiency in power-to-heat systems, can initially be advantageous over other conversions (for example power-to-gas).
- the first energy converter module 200 there is a computing unit 210/a computing center 210 as the first energy converter 210, which carries out computing operations and/or storage processes using the electrical energy E provided, a part or a large part of the electrical energy E is converted into thermal energy T and makes it usable for the system 1000, for example by feeding the thermal energy T, which was otherwise usually given off as waste heat to the environment or to the environment via cooling systems, into the heat supply of the building 2000.
- the electrical energy E introduced into the exemplary system 1000 can be converted very effectively into thermal energy T and, at the same time, computing capacity and storage capacity can be provided by means of a computing unit 210/a data center 210, which is increasingly happening in the course of the digitalization of society and a wide variety of processes more important and will therefore be in demand in the next few years or decades.
- the computing unit 210/the data center 210 can be designed, for example, as a server structure with worldwide access options and/or can be used as an intranet, for example within large companies/groups, thereby providing added value for the companies.
- first energy converters 210 can also be used as first energy converters 210, since these devices often have a large number of drives and / or hydraulic units, some of which need to be cooled.
- Another example is the friction of the tool of a machine tool when machining a workpiece, which also generates heat which is often carried away from the workpiece with a so-called cooling lubricant.
- chemical systems that, for example, “incidentally” generate heat during the chemical conversion of substances can also be used as first energy converters 210.
- a short-term storage 220 (or diurnal storage) as the first energy storage 220/230 for the short-term storage (for example several hours to a few days) of the thermal energy T, in particular that required during the day and overnight Amounts of thermal energy T, which, depending on requirements, can also be very susceptible to fluctuations in the amount of energy per unit of time, are to be provided in the consumer module 600 (thermal consumer module 600) of the building 2000 and react at short notice to an increased demand or, conversely, to a lower demand to be able to.
- buffer storage 220 for example in the form of a layered storage with layered storage of thermal energy depending on the temperature level
- buffer storage 220 can prove to be extremely advantageous, as they are comparatively limited in their amount of storable thermal energy T and are therefore exhausted quite quickly, but at the same time again can be quickly loaded with thermal energy T and in a comparatively short time.
- the fluctuations that occur in the consumption of thermal energy T in the consumer module 600 of the building 2000 over the day/over the night can be advantageously addressed.
- Another component of a system 1000 can also be a storage of thermal energy T, which can store a comparatively very large amount of thermal energy T in the medium term (several days to several weeks) or long term (several weeks to several months) and in doing so partially
- the amount of heat required in the building 2000 can be provided to the consumer module 600 over a long period of time (sometimes over several months).
- Such thermal storage of the first energy storage 220/230 also referred to as seasonal storage 230/long-term storage 230 (or seasonal heat storage or seasonal storage)
- the short-term storage 220 and the long-term storage 230 of the first energy storage 220/230 have a direct connection/direct active connection for exchanging amounts of heat, so that, for example, the amount of heat stored in the long-term storage 230 in the long term via a short and therefore quick path (or parts thereof) can be made available to the short-term storage 220 if, for example, the amount of thermal energy T provided or converted by the exemplary data center 210 can no longer cover the consumption of thermal energy T of the building 2000.
- an exchange of heat (for example from short-term storage 220 to long-term storage 230) can advantageously take place via a heat exchanger, whereby the temperature level would be reduced.
- a heat pump see for example heat pump 510 with the supply of electrical energy E (as an exemplary first form of energy) with an increase in the temperature level, the long-term storage 230 can be shifted back into the short-term storage 220.
- thermochemical heat storage 240 Another advantageous component of the exemplary system 1000, in particular of the first energy converter module 200, can be a fifth energy storage 240, which is designed as a thermochemical heat storage 240.
- Excess heat can, for example, be bound in an endothermic chemical reaction using silica gels, metal hydrides, zeolites or metal oxides in an oily suspension, such as hygroscopic oxides such as boron oxide (conversion of thermal energy T into storable chemical energy C) and without loss over long periods of time as chemical energy C stored/stored.
- heat thermal energy T
- conversion of stored chemical energy C to thermal energy T conversion of stored chemical energy C to thermal energy T
- the reaction products of the exothermic reaction correspond to the starting materials of the endothermic reaction Reaction, so that overall a reversible process for storing and withdrawing thermal energy is created.
- the long-term storage 230 can also be designed as a thermochemical storage 240 (fifth energy storage 240) in order, for example, to store thermal energy T in a space-saving manner compared to an earth basin heat storage.
- a second energy converter module 300 can be an advantageous component, wherein the second energy converter module 300, in contrast to the first energy converter module 200, converts the electrical energy E into chemical energy C (for example third form of energy) (power-to-gas) and is also able to can be to convert the chemical energy C back into electrical energy E and / or thermal energy T.
- chemical energy C for example third form of energy
- power-to-gas power-to-gas
- the second energy converter module 300 can have, for example, a second energy converter 310, for example an electrolysis unit 310, which converts electrical energy E into chemical energy C through a redox reaction with water (water electrolysis) to produce thermal energy T, wherein in the water electrolysis the water in Oxygen (O 2 ) and hydrogen (H 2 ) is split.
- a second energy converter 310 for example an electrolysis unit 310, which converts electrical energy E into chemical energy C through a redox reaction with water (water electrolysis) to produce thermal energy T, wherein in the water electrolysis the water in Oxygen (O 2 ) and hydrogen (H 2 ) is split.
- the latter of the two can be advantageous, for example, for a conversion, for example in a third energy converter 330 (for example combined heat and power plant 330, which burns the hydrogen H 2 , or fuel cell 330, which converts the hydrogen H 2 into electricity while supplying oxygen O 2 , with waste heat in both cases arises) can be used to produce electrical energy E (electricity) and/or thermal energy T (heat) if required for the consumer module 600 (thermal consumer module 600) and/or for the consumer module 800 (electrical consumer module 800) of the building 2000 generate.
- a third energy converter 330 for example combined heat and power plant 330, which burns the hydrogen H 2 , or fuel cell 330, which converts the hydrogen H 2 into electricity while supplying oxygen O 2 , with waste heat in both cases arises
- the second energy converter module 300 has a second energy storage 320 for storing the chemical energy C (such as hydrogen H 2 ) that was formed/generated in the second energy converter 310 (for example in the electrolysis unit 310).
- the chemical energy C such as hydrogen H 2
- An advantage of this The energy storage method is that a comparatively large amount of energy can be stored in a comparatively small space, since gaseous substances in particular as carriers of chemical energy E (for example hydrogen) are very highly compressible and storable under appropriate pressure. This means that storage for large amounts of chemical energy C can be advantageously provided in or on a building even when space is relatively small.
- the second energy converter 310 and the third energy converter 330 can be designed as an assembly 340, in particular as a reversible fuel cell 340, which can convert an energy amount of electrical energy E into an energy amount of chemical energy C in a process, this chemical energy C being converted back into the second energy storage 320 can be stored, and can carry out this process in reverse, from chemical energy C to electrical energy E.
- thermal energy T is generated, which, like that in the electrolysis unit 310 and/or in the fuel cell 330/in the combined heat and power plant 330 resulting thermal energy T, can be stored in the first energy storage 220/230 of the first energy converter module 200.
- the reversible fuel cell 340 as a second energy converter 310, in addition to the advantageous reduction in the number of individual components within the exemplary system 1000, it is also possible to effectively temporarily store excess amounts of energy, for example generated by the wind turbine 110 or by the photovoltaic unit 120, in the second energy storage 320 (for example as gas bottles or, due to the lower pressure of 30 to 40 bar, as a large-volume plastic tank or comparable; furthermore, in addition to gaseous storage, the chemical bonding of H 2 in ammonia can also take place as a liquid, for example if pressures of at least 9 bar can be applied during storage).
- the second energy storage 320 for example as gas bottles or, due to the lower pressure of 30 to 40 bar, as a large-volume plastic tank or comparable; furthermore, in addition to gaseous storage, the chemical bonding of H 2 in ammonia can also take place as a liquid, for example if pressures of at least 9 bar can be applied during storage).
- the operator of the exemplary system 1000 can be provided with an additional option, in addition to storing the excess amount of energy as thermal energy T in the corresponding short-term storage 220 or long-term storage 230, of storing the excess energy as chemical energy C, here too again aspects such as the efficiency of the respective conversion of electrical energy E into thermal energy T or into chemical energy C and/or the need for thermal and/or electrical energy T/E could be taken into account.
- Advantageous reversible fuel cells 310 can be, for example, polymer electrolyte fuel cells (PEM) or solid oxide fuel cells (SOFC), the latter of which can partially achieve a power-to-power efficiency of up to 70%. Since this efficiency is significantly lower than in power-to-heat applications, the use of power-to-gas can be particularly advantageous if there is a significant excess of electrical energy E in the exemplary system 1000 and the heat storage devices 220, 230, for example are already very well or completely filled or the heat storage devices 220/230 are too small or not available, so that the power-to-gas system can be used as a supplement or alternative to the heat storage devices 220, 230.
- PEM polymer electrolyte fuel cells
- SOFC solid oxide fuel cells
- first, primary load-dependent energy converter 210 for example in the form of a machine tool, a computing unit, etc.
- the storage options for thermal energy T through short-term storage 220 and long-term storage 230 the conversion option of electrical energy E into chemical energy C through a second energy converter 310 (for example as an electrolysis unit 310) and corresponding storage options (second energy storage 320 for storing chemical energy C) as well as the possibility of converting chemical energy C into electrical energy E and / or thermal energy T
- Both electrical energy E and thermal energy T are advantageously made available to the consumer modules 600, 800 (thermal consumer module 600/electrical consumer module 800) of the building 2000 continuously and as needed.
- Discontinuous energy sources such as wind 10 and solar radiation 20 can have very different strengths depending on the weather, time of day or night, season and location (e.g. equator or poles as extreme examples) or, for example, fail completely or be unavailable.
- the energy supply based on these discontinuous energy sources 10, 20 in the exemplary system 1000 can therefore be as high as possible (for example in summer, cloud-free and at midday when the solar radiation is 20 am is strongest and, for example, at the same time there is a correspondingly strong wind 10) to complete standstill (for example at night and when there is absolutely no wind, also referred to as a “dark calm”).
- intermittent energy sources 10, 20 are very dependent on circumstances and cannot provide continuous energy (a continuous amount of energy), it may be appropriate to use a corresponding exemplary system 1000.
- various forms of energy for example electrical energy E, for example as a first form of energy, thermal energy T, for example as a second form of energy and chemical energy C, for example as a third form of energy, as well as their possibilities for storage and conversion into the other Forms of energy can be used to recharge the storage options when the energy supply from the discontinuous energy sources 10, 20 is over-covered in relation to the energy consumption in the building 2000 or to consume the stored amount of energy when the energy supply is under-covered by the discontinuous energy sources 10, 20 in relation to the energy consumption of the building 2000.
- electrical energy E (first form of energy) can be used as a continuous energy source through the public power grid 40, as well as through discontinuous energy sources such as wind 10 and/or solar radiation 20, which can be generated, for example, by means of a wind turbine 110 and/or a photovoltaic unit 120 of the first energy supply module 100 are converted into electrical energy E and made available to the first for further use
- Energy converter module 200, the second energy converter module 300 and / or the electrical consumer module 800 of the building 2000 are supplied.
- the third energy storage device 130 can be designed as a vanadium redox flow battery or as a lithium-ion battery or lithium iron phosphate battery.
- the excess electrical energy E is either stored directly in the third energy storage 130 and/or converted into storable gas by, for example, the electrolysis unit 310/reversible fuel cell 310.
- the exemplary system 1000 can have a second energy supply module 400, which generates chemical energy C based on a second energy source 30 by means of a second energy generator 410.
- the second energy source 30 can in particular be biomass 30 as a renewable raw material.
- wood 30 in the form of logs, pellets, etc. is particularly suitable for this.
- other types of biomass for example other plant components
- the chemical energy C generated can, for example, be stored again, for example in corresponding stores comparable to the second energy stores 320 of the second energy converter module 300.
- the second energy provision module 400 can have a fourth energy converter 420, which converts the chemical energy C generated by the second energy generator 410 into thermal energy T.
- a fourth energy converter 420 which converts the chemical energy C generated by the second energy generator 410 into thermal energy T.
- the chemical energy C is converted into thermal energy T by combustion and made available to the exemplary system 1000 for use, for example in the form of heating the hot water circuit/hot water network of the building 2000, and further the thermal energy T ( at least partially) can be used to generate the chemical energy C in the second energy generator 410.
- wood gasification boilers can advantageously be used for this purpose, in which the wood gasification by the second energy generator 410 (wood gasifier 410) is spatially separated from the wood gas combustion by the fourth energy converter 420 (wood gas burner 420) takes place, but the wood gasification boiler (having second energy generator 410 and fourth energy converter 420) is essentially an assembly.
- the second energy supply module 400 can have a fourth energy storage 430 for storing the thermal energy T (for example second form of energy), wherein the fourth energy storage 430 can, for example, be in no or direct operative connection with the first energy storage 220/230 for storing the thermal energy T in order, for example, to be able to exchange an amount of thermal energy T with one another.
- the fourth energy storage 430 can, for example, be in no or direct operative connection with the first energy storage 220/230 for storing the thermal energy T in order, for example, to be able to exchange an amount of thermal energy T with one another.
- Another example aspect of the example system 1000 may be additional heat-generating devices.
- the computing unit 210/the computing center 210 only generates heat in a corresponding amount if correspondingly extensive computing and/or storage operations are carried out by the computing unit 210/the computing center 210 (primary load-dependent conversion of electrical energy E into thermal Energy T), the required amount of heat cannot potentially be generated at all times.
- the exemplary system 1000 has a heat pump 510 of an additional heating module 500, which increases the amount of thermal energy T in the system 1000 by reversing the heat-power process, in which additional electrical energy E may also be required. elevated.
- the heat pump 510 uses the thermal energy T stored in the long-term storage 230 of the first energy storage 220/230, further increases this amount of thermal energy through the reverse heat-power process and then feeds it into the system 1000.
- the consumer module 600 (thermal consumer module 600) of the building can have a drinking water consumer 610 with heated water and also one or more radiators 620 (or surface heating systems 620; see below) for heating the room air of the building 2000 as a consumer for thermal energy T exhibit.
- the provision of drinking water (including heated drinking water) and the heating of the air in the building 2000 are usually basic requirements for every residential or office building.
- the building 2000 can have an outbuilding 2100 (e.g. a workshop, a barn, a stable, etc.) which has at least one or more radiators 650 or surface heating systems 650 (such as underfloor heating, wall panel heating or ceiling heating) for heating the room air of the outbuilding 2100 .
- the difference here lies particularly in the flow temperature that the respective heating systems require.
- a 650 radiator usually requires a flow temperature of around 55 °C
- a 650 panel heating system usually only needs a flow temperature of 35 °C.
- Another exemplary aspect of the exemplary system 1000 may be an outdoor pool 700, whose heat requirements are also supplied from the building's heating network 640.
- the special features of such an outdoor pool 700 can be its large amount of water and its exchange with the outside air at appropriate ambient temperatures. Both result in a large power loss Evaporative cooling (depending on the size of the water surface of the outdoor pool 700) and heat loss to the environment (depending on the outside temperature).
- thermal energy T from the exemplary system 1000.
- the large amount of water in the outdoor pool 700 (additional consumer 700) can play an advantageous role, since correspondingly large amounts of thermal energy T are “used” for the (additional) heating of this pool and can thus be withdrawn from the exemplary system 1000.

- it can be too large and all thermal or thermochemical storage units have already been filled and therefore some kind of emergency cooling is required in order to reduce the total amount of energy (in particular total thermal energy amount) from the exemplary system 1000, for example an outdoor pool 700 can be used as additional thermal consumer 700 may be provided.
- the overall amount of heat in the exemplary System 1000 can be significantly reduced.

- a second energy supply module 400 which is designed as a wood gasification boiler (having second energy generator 410 and fourth energy converter 420).
- FIGS 4a to 7b which each show diagrams, deal with the topic of the energy balances of chemical, electrical and thermal energy C, E, T, particularly with regard to generation, consumption and storage by the respective modules or units, whereby the Diagrams show the energies as the area under the respective curve (integral) as power P in kW (y-axis) over a period of time t (x-axis).
- Fig. 4a shows a diagram of heat absorption (values in the negative area of the power axis represent the consumption of heat) and heat emission (values in the positive area of the power axis represent heat generation) of the modules 200, 300, 500, 600, calculated as an example in a model calculation , 700 of the exemplary system 1000 in kW over a time range of the first quarter of a year (here the year 2022 as an example), starting from January.
- the heat output of the first, primary load-dependent energy converter 210 which is designed here as a server for example, has two heat quantities 210Ta 210Tb.
- the server has a heat quantity 210Ta due to a base server load and a load-dependent heat quantity 210Tb due to a specific utilization of the server by computing and/or storage processes. It can also be seen that the base load of the server emits a continuous amount of heat 210Ta over the quarter, while the load-dependent amount of heat 210Tb shows individual smaller fluctuations (for example due to isolated, significantly low server utilization).
- a quantity of heat 310Ta released by the electrolysis unit 310 can be seen in the diagram according to FIG in the first quarter of the year, especially at the beginning of the year, and then decrease towards March.
- Fig. 4b shows the continuation of the diagram from Fig. 4a over a time range of the second quarter of the exemplary year, starting from April.
- the thermal energy E can be used as early as April of the year to generate a comparatively large amount of heat 700Ta for heating and maintaining the desired temperature of the building Outdoor pools accommodate 700.
- the electrical energy E available in the model calculation based on weather data from the exemplary location (Thuringia, Thuringian Basin region), which is converted due to excess in the exemplary system 1000 in the electrolysis unit 310 and thus to generate the amount of heat released 310Ta is available. Since the days in April are still relatively short compared to summer, solar yields are only available for a limited time, so that the hydrogen storage 320 is discharged again overnight in order to make electrical energy E available for the technical systems.
- the fuel cell 330 thus provides an amount of heat 330Ta to generate the required electrical power, which also contributes to the required amount of heat 700Ta.
- Fig. 4c shows the continuation of the diagram from Fig. 4b over a time range of the third quarter of the exemplary year, starting from July.
- Fig. 4d shows the continuation of the diagram from Fig. 4c over a time range of the fourth quarter of the exemplary year, starting from October.
- the amount of heat from the seasonal storage 230/thermal long-term storage 230 is also increasingly used, which is fed into the exemplary system 1000 via the heat pump 510 as the amount of heat released 510Ta and from the respective consumers 610, 620, 650 and 700 can be used, with the outdoor pool 700 still being heated in October.
- the heating of the outdoor pool 700 can therefore still be seen in October in the present model calculation, as the generation of electrical energy from renewable energy sources (such as wind 10 or solar energy 20) is already declining significantly in October, so that more and more electricity is being generated from hydrogen.
- renewable energy sources such as wind 10 or solar energy 20
- the outdoor pool 700 would only be heated as long as there was a real excess of heat in the exemplary system 1000. Only when the excess heat would no longer exist or a lack of heat would occur in the system 1000 would the exemplary system 1000 switch on the heat pump 510 to generate additional amounts of thermal energy 510Ta.
- Fig. 5a shows a diagram of a charging power calculated as an example in the model calculation (values in the positive range of the power axis represent the absorption of chemical energy C) and extraction power (values in the negative range of the power axis represent the release of chemical energy C) of the second energy storage device 320, which is designed as a hydrogen storage device 320, of the exemplary system 1000 in kW over the time range of a year (here, for example, the year 2022) .
- the charging power is below the extraction power of the second energy storage 320, which therefore leads to a sometimes significant reduction in the fill level of the second energy storage 320 within a short period of time (see also Fig. 5a).
- the excess thermal energy T in the exemplary system 1000 is used to load/store the thermal long-term storage 230, as can be seen in particular in the periods from June to mid-September in FIGS. 4a to 4d. Since there is no removal of thermal energy T from the long-term thermal storage 230, the filling level of the long-term thermal storage 230 increases correspondingly quickly (see FIG. 7b).
- the loading of the long-term thermal storage 230 can be more than 100% (for example approximately 110%), which is possible, for example, with a long-term thermal storage 230 designed as an earth-coupled heat storage if, for example, it has a temperature of more than 25 ° C, which is 100 % fill level would be considered.
