Heat 2 Power

Rethinking the Energy Transition

Increase efficiency, reduce costs: How industry and the whole planet can benefit from the energy transition. With two new developments in the "Power to Heat" and "Heat to Power" areas, the energy revolution can come.

The future of energy storage and power generation

Here are the game changers! Forget H₂, power to gas, lithium-ion batteries and microturbines, gas engines and large diesel aggregates. Instead, read here about the technologies that will really matter in the future:

How heat recovery can work in industry: How to convert previously unused waste heat into electricity.
How regenerative energy generation can be designed to be base load capable: How to store excess power.
How you can generate electricity from renewable sources during dark periods.
This is how you improve the efficiency of CHP units, small power stations or ship propulsion systems and at the same time reduce pollutant emissions.

Power to Heat

A modular high-temperature heat storage that systematically eliminates all known disadvantages of this well-known technology:

Any power source possible
Performance range infinitely scalable
Simple construction with inexpensive materials.
100% in-house production possible
Separate media circuits, saves decoupling of heat to a secondary circuit
Modular structure with hot/cold temperature gradient. There is always a suitable temperature somewhere in the system
Simultaneous loading and unloading
Countercurrent heat exchange across all modules for maximum efficiency
Continuous operation, even when there is no heat input
High temperature range, especially use of lower temperatures

Storage of industrial waste heat
Intake of excess power from renewable energy generation
Continuous release of stored heat to a heat engine for reconversion

Heat to Power

A modular hot gas engine system that systematically eliminates all known disadvantages of this well-known technology:

Highly efficient generation of electricity from heat
Any heat source is possible: intermediately stored excess power from regenerative energy generation from heat storage, industrial waste heat, residues that would otherwise only be burned off, LNG, biogas, etc.
Heat input through central burner on the device or hot-air circulation system
Output range up to >15000 kW
Extremely simple structure with few elements
Components with a simple basic design throughout
High proportion of in-house production possible
Separate circuits between cold and hot areas
Modular design with pairs of hot/cold cylinders
Multi-cylinder configurations for maximum performance
Closest possible approximation to the theoretical thermodynamic process, no overlapping of the cycle steps
Reduction of all loss mechanisms (friction, heat loss, etc.)
Simultaneous expansion and compression in doubleacting cylinders
Continuous countercurrent heat exchange in just one regenerator
No dead zones for a consistently high compression ratio
High constant temperature difference between hot and cold side
Efficiency around 50%

Benefits for the Energy Transition

A "Power-to-Heat-To-Power" system with the two innovations presented here is more efficient and cheaper than the existing solutions for energy storage.
They are not only more efficient individually than previous solutions, the synergy is that they can use a common working gas without conversion into steam and without further heat extraction to other circuits as a tandem without additional equipment: air. It's that easy.
The hot gas engine system is suitable for using any heat source, such like biofuels (bio-LNG, H₂, etc.), or heat from the thermo storage tank for converting into electricity. You don't need any other back-up power plants.
With manageable effort, excess power can be smoothed or temporarily stored, thus making renewable energies base load capable.
High-temperature heat storage and the new Stirling plant can also be placed decentrally as a tandem, for example linked to a district, and then used as part of a combined heat and power system.
The "Power to Heat to Power" concept proposed here reduces the effort for grid expansion, gas power plants, fuels and other storage solutions immensely.

Base load smoothing of RE generation and continuous provision of electricity with thermal storage and new hot gas engine system: Heat is circulated indefinitely and cannot leave the system. Countercurrent heat exchange in the heat accumulator and in the hot gas engine system means that no joule is wasted, low temperatures are used to generate electricity and efficiency is optimised. All this with the simplest structure and minimal complexity.
