Green technologies are progressing in the field of mobility and energy production. It is a common aim to reduce or to completely avoid CO2 emissions in order to comply with national environmental regulations. However, it does not make sense in every technical application to choose a fuel cell or a pure battery electrical system. Highly efficient combustion-based machines in hybrid systems will continue to be necessary in certain use cases, even in the utilization of hydrogen.
This patent portfolio describes an innovative thermodynamic process for the operation of a non-air-breathing combustion turbine with a drastically increased degree of efficiency. This new extraordinarily compact class of liquid oxidizer fed combustion turbines has the potential to surpass the efficiency of every known internal combustion engine and even the H2 fuel cell.
Any liquid or gaseous substance can be used as fuel, including hydrogen, or ammonia which is known to burn CO2 free. According to calculations the described turbo-electric system can achieve a thermal efficiency of 70% in a mobile unit (electrical energy gain in relation to the calorific value of the fuel used). Considering the energy expenditure for the production of the liquid air used, the efficiency is still above 60%. The system is more compact, lighter, significantly cheaper to manufacture than a fuel cell and does not require any preheating. The system works even at cryogenic temperatures under the most adverse conditions, where a fuel cell or battery fails.
Every imaginable vehicle can be powered with it, be it on the ground, on rails, at sea, in the air or even under water or in space. The concept of a very economical commercial hybrid turboprop aircraft engine is also available. Local CO2 emissions are less than half those of a diesel-powered vehicle on road. Furthermore the patent describes a vehicle which is equipped with the turbine system and an alternative air conditioning system.
Since the claims in the final version were divided into a process part and three device parts, the patent covers even any stationary machine which works according to the thermodynamic high pressure process described. In a combined cycle (an additional cycle using waste heat), the turbine system could achieve a thermal efficiency of more than 90% (useful electrical power) in a power plant, far more than is possible today in the most modern combined cycle power plant. The specific CO2 emission in natural gas operation is 260gCO2/kWhel. The idea can also be implemented on a large power storage plant, which works on a similar principle as LAES, but is more efficient, compact and cost-effective due to the extraordinarily high energy and power density. Storage medium can be e.g. cold liquefied air + electrolytically generated cold liquid hydrogen. Thermal storage is not absolutely necessary here.
Recently named companies in Europe have expressed their interest in a working prototype. This opens up a chance for licensing in the future. The inventor and seller of the patent portfolio offers his support for further development. More information can be provided on demand.

Financial information

With an assumed market share of 5-15%, the market in the patented countries is in the upper three-digit million range per year. The implementation of turbo-electric trucks, locomotives, passenger propeller aircraft, submarines, powerplants, CHPs was described in more detail. Versatile fuel-oxidizer combinations are possible. In any case, large amounts of CO2 can be saved compared to a diesel engine or a gas turbine.
A prototype of a turbine does not yet exist but there are specific construction plans.. Thus, the development status according to the NASA method would be classified as TRL2. The seller offers his support as an experienced designer of internal combustion engines. It would be a pleasure to assist you.
Various information material can be offered on request. Among other things, a white paper, claim tables, concrete application examples CAD-Models.
