Sistema flexible y rentable para transformar energía térmica residual en electricidad


Oferta Tecnológica
Una pyme austríaca especializada en tecnologías de producción combinada de calor y electricidad (CHP), energías alternativas y procesos ecológicos ha desarrollado un sistema para transformar energía térmica residual en electricidad (hasta 100 kW). El calor puede proceder de diferentes fuentes, desde energía solar y escape de motores hasta sistemas de gasificación de biomasa. Se trata de una tecnología innovadora, flexible, sencilla, rentable y con un funcionamiento y mantenimiento sencillos. La empresa busca socios con el fin de establecer acuerdos de cooperación técnica, investigación, financiación y joint venture.


Flexible, cost-effective system to convert waste thermal energy into electricity
An Austrian SME has developed a system to convert existing thermal energy into electricity up to about 100 kW. The heat can come from a number of sources ranging from solar heat and engine exhaust to biomass heating/gasification systems. Up to 15% of the thermal input can be converted into electric power. The innovation is flexible, simple, cost effective and easy to operate/maintain. The SME seeks technical and/or research cooperation in addition to financial and/or joint venture agreements.
The Austrian SME is active in CHP (combined heat and power) technologies and has significant experience in alternative energy and environmentally friendly processes.

A recent development involves a rotary expander which can be used to convert waste thermal energy into electricity. The waste heat can come from a number of sources including: engine exhaust; biogas; CHP systems; any biomass heating/gasification system or high-temp solar thermal plants. The product is relatively simple to manufacture and well-suited for mass production. Its design is low maintenance and easy to use. In its current state, the normal operating temperature is up to 200° C, but future models will be able to function at higher and lower operating temperatures. The current design runs on steam, but plans for the use of different expansion media are being explored.

The solution provides a viable alternative when standard electricity generation techniques such as turbines are not suitable nor financially viable due to low temperatures.

The technology can be retrofitted as an add-on component to other solutions which produce or consume heat. The resultant electricity can help to make the larger system self-contained or to enable it to run more economically/profitably. Potential areas of application include thermal processes in agriculture, district heating, distributed power etc.

The machine is based on a modular design, which can be easily down or upgraded. This allows for standardised systems, which are still very flexible. Solutions are also available which allow the technology to operate under partial load. The planned pricing structure for the technology will be in line with current prices for decentralised CHP systems.

While the basic principle of the machine is well established, there is to date no such unit on the market for applications such as those proposed. Progress in technology and new IT methods have given way to new methods of implementation.

A prototype of the technology has already been built and is in operation at a test facility, with plans for a market launch in 2016. For this reason a number of cooperation partners are sought.

Some patents have already been granted and others are pending. The SME is interested in exploring application-oriented modifications, adaptations or improvements to the machine in its current state with the goal of optimising not only individual components, but also the entire application.

With this in mind, partners are sought for technical cooperation with a view to further developing the innovation. The SME would also be open to a joint venture or a financial agreement in the form of investing in the technology. A research cooperation agreement would also be of interest, where the SME would join established consortiums for EU-funded projects. While they already have experience in co-ordinating such projects, in this instance the preference would be to join a consortium with a co-ordinator already in place.

Advantages and Innovations:
While the basic principle of the machine is very established, the main advantage of the technology´s patented geometry is to reduce leakage and wear.
It also allows for the use of new materials, specifically polymers.

Another significant advantage is the cost effectiveness, as this solution can be used in applications where other technologies have been ruled out due to high costs.

The thermal output is provided as exergy which can be used for heating or cooling.

The robust design is an ideal basis for future expansion of the application range and specifically for improving efficiency.

The compact size (300x300x300mm for 10kW) makes it suitable for many applications.

Suitable for serial production.
Stage of Development:
Prototype available for demonstration
Secret Know-how,Patent(s) applied for but not yet granted,Patents granted
CommeR Statunts Regarding IPR Status:
An EU patent has already been granted.
A further application has been made to, in general, protect the use of waste heat in a specific area.

Partner sought

Type and Role of Partner Sought:
Partners are sought, where waste energy recuperation is a good supplement to their own business and where they could benefit from the new solution, e.g.:
-- Technology partners, specifically with experience in tribology or in ORC (Organic Rankine Cycle) media
-- Commercial and/or investment partners interested in investing in the project or in a joint venture

The ideal partner should be in a position to jointly work with the Austrian SME on further development of the product, as well as various suitable applications. The preference would be for this further development to be part of an EU Project or some other publically-supported initiative.

The Austrian SME would also be open to commercial/financial agreements in the form of co-financing or joint venture.
