CO2 neutrality is feasible. With deep geothermal energy.
The fact is that the energy supply as we know it has had its day. Renowned scientific institutions around the world have been pushing for a green transformation for years. This is where deep geothermal energy comes into play. It uses the hot water in deep-lying rock strata, so-called aquifers, for energy production. In combination with decentrally organised circuits connected to it, including fuel cells and future geo-storage facilities, we can achieve an energy balance at the appropriate locations that will soon be the standard everywhere.
Our earth: an inexhaustible green resource.
Geothermal energy: the overview for those in a hurry.
Geothermal energy makes it possible to tap the earth's thermal energy in a climate-neutral way and use it to supply heat and electricity to buildings. Boreholes several hundred metres to several kilometres deep help to pump the hot water contained in the deep layers of rock towards the earth's surface. The technology can be used whenever a site has hot water beneath it in the earth below. This is the case at many locations in Germany. Geothermal energy lends itself to building for a number of reasons: Buildings gain a decentralised, self-sufficient energy supply, can release the surplus to connected systems and thus become a driver for green change.
It begins with drilling. It ends with a decentralised, green energy supply.
The animation above shows a forward-looking setting for a decentralised energy supply. The geothermal power plant generates green heat, cold and electricity (central axis) via the aquifer well (bottom centre). The electrical energy can be used for buildings, electromobility and other purposes and, if necessary, stored in a battery (left power circuit, centre). The power source operates another circuit with an electrolyser, which supplies a fuel cell circuit (right hydrogen circuit, centre). A vision for the future is the storage of green hydrogen in so-called geostores, which store the element in an ecologically conscious way for later use. Deep geothermal energy has parallels to the HotStone process, which we are also promoting.
Decentralised thinking: from the earth to the periphery - beyond the bounds of the project.
Our current grids cannot yet store the generated energy effectively enough. This is where the vision of geostorage comes in (see diagram, below right). In geostores, green hydrogen can be stored deep in the earth in naturally occurring cavities. naturally occurring cavities. The advantage: some possible storage areas have already been identified, since extensive exploratory drilling for raw materials was undertaken in Germany at the beginning of industrialisation. In the event of excess demand in the system the hydrogen can be converted back into electricity. With innovative solutions like geostorage systems, we can encourage stakeholders from the energy industry to rethink without ignoring economic factors.
From the depths of time: HotStone process.
With planetary power towards the future: the HotStone process is another geothermal building block on the way to a green energy economy. With HotStone, the hot thermal water of the aquifer rock layers is made available for green energy production via a single pipe system. HotStone is a closed system that can be intelligently integrated into a green, decentralised district heating system. The technology can be used to develop and exploit sustainable cycles.
Hello, new setting. Hello, industry.
With decentralised solutions like deep geothermal energy, the green transition is realistically achievable. We start where the most energy is demanded. Geothermal power plants function completely autonomously and can be seamlessly integrated into existing structures. The electricity generated can be distributed via intelligent grids and the hot thermal water can be used for district heating. Smartly set feed-in points feed a decentralised system: peaks in the form of overloads are thus a thing of the past - electricity parks are also a thing of the past if we decentralise the energy supply. We at DES do not see ourselves as operators of plants, but want to establish them in close cooperation with politics and industry. Let's start joining forces for a green energy transition and realise new standards of economic efficiency and ecology with decentralised settings.
Let's start a new chapter in the construction and energy industry together.
