Czech R&D Institution have developed a cogeneration unit for biomass based on the principle of Organic Rankine Cycle (ORC) which generates electricity (3 kW) in addition to heat (50 kW) that can be installed in a container design with the ability to run on poor quality fuel intended for clients looking for energy independence. The technology is offered on the basis of a license agreement.
Electricity is still used as a source of heating in many buildings, which is extremely disadvantageous in terms of operating costs.
Developed cogeneration unit based on ORC technology for wood chips (biomass) can be imagined as an automatic boiler which generates electricity (3 kW) in addition to heat (50 kW), a small version of a conventional power station (micro electric power station) that can be installed in a container. The device is designed as ORC unit with outputs corresponding to the consumption of client´s needs - e.g. an apartment house, mountain chalet, guesthouse, production hall etc.
Biomass in cogeneration production of electricity and heating (CHP ORC) unit is intended especially for clients who are looking for energy independence and security and the highest possible use of available local resources.
Czech R&D Institution founded as an independent institute of technical university focused on research activities related to energy efficient buildings offers technology, which has the ability to burn very poor quality fuel and to operate without the power. If the unit´s electrical efficiency is sufficiently high, it can also be used as the main source of electricity e.g. in places where internal combustion engines are currently primarily used and where is no or problematic connection to the public grid.
Micro-cogeneration achieves a high energy efficiency by converting the primary energy source into electricity and heat at the level of the end user. This reduces the energy losses associated with the generation and distribution of energy within central production.
The unit can be integrated into the heating systems of existing buildings because of micro-CHP systems produce relatively high temperature heat and can be well connected to existing electrical infrastructure. It could also be used in "Smart Grids" concept.
The device is unique especially by the use of a lamellar expander with a mechanical output in the order of kW units, which makes the device also suitable for use in small power plants. This is a relatively simple production technology that has the potential of low production costs when introducing series production. Another important component is the exchanger system, which is designed so that the equipment achieves very good separation efficiency.
The whole technology including accessories is placed in a standardized container. Depending on the client´s request, fuel management can be placed in another container. The equipment in the container is fully functional, it only needs to be connected to the electricity and to the heating system. Operation is fully automatic with remote diagnostics.
Technology is offered as demo testing unit and/or commercial installation. The disclosed technology is offered on the basis of a license agreement.
- Specific area of activity of the partner: Partner sought would be interested in licensing disclosed technology for exercising intellectual property rights and know-how and in manufacturing, selling, renting or developing products manufactured using this intellectual property rights and know-how.
The main novelty of developed technology lies in simplicity of the concept in terms of production and maintenance, control system and very simple installation due to placing in the container.
The unit has the following advantages over currently available technologies:
- Ability to process even very poor quality fuel without treatment
- Massive combustion part design – low risk of damage by unsuitable fuel
- Container design – simple and quick installation
- Compact design – contains all the necessary systems for operation
- Easy service
- Emergency power supply capability
- Remote diagnostics and control
- Fully automatic operation
- Affordable technical support in a short time
- Low legislative load when permitting installation
- Possibility to connect battery storage, photovoltaics (supplied as a whole)
- Ability to work without connection to the public grid (in case of battery storage installation)
Prototype available for demonstration - Concept is planned for demonstration in Prague. Previous generation concept by CTU has been tested in Mikolajice, Moravian-Silesian Region, Czech Republic (NUTS3).
