Photobioreactor to biosequestration of CO2 from immobilized algae or cyanobacteria biomass
Summary:
An R-Y-D unit from North-East Poland created a photobioreactor to biosequestration of CO2 from immobilized algae or cyanobacteria biomass.
The proposed photobioreactor is an innovative device for biological sequestration of carbon dioxide, which directly affects the reduction of emissions of greenhouse gas into the atmosphere.
The invention is currently under laboratory tests. The R-Y-D unit is looking for research and technical cooperation for further joint development or license agreement.
Description:
The Polish research and development unit actively operating in the field of biotechnology created a photobioreactor to biosequestration of CO2 from immobilized algae or cyanobacteria biomass.
Due to the constantly increasing level of greenhouse gases in the atmosphere, there is a need to reduce anthropogenic emissions of carbon dioxide, even from sources of minor importance in relation to energy transformations. Current CO2 emissions caused by mankind is 28 billion tons per year. It is estimated that at current trends, world production of CO2 by 2030 will increase by 55% and in the same time CO2 emission in EU will increase by 5%.
The aim of the invention is to create new construction of equipment to remove CO2 from exhaust gas and waste gases from different industrial sectors, e.g. from the food industry from the manufacturing process of yeast, biogas production systems, combustion systems of liquid and gaseous fuels, the technology of converting carbohydrates. The invention allows for effective removal of carbon dioxide from gases with a high concentration of CO2. At the same time the device is characterized by a significantly lower cubic capacity compared to currently used solutions using CO2 biosequestration processes.
Operation of the described technological solution is based on the use of algae or cyanobacteria which biomass is immobilized in a specially designed gel or plastic capsules and placed in photobioreactor. The solution can be applied in systems producing exhaust gases and waste gases with a high concentration of carbon dioxide. For this type of facilities one can include local district heating and power plants, as well as agricultural or disposal biogas plants.
The invention, thanks to its design, is assumed to achieve a very high concentration of algae or cyanobacteria biomass through its immobilization in capsules. This eliminates the phenomenon of lowering the pH, that is acidification of the environment in which algae and cyanobacteria can develop as a result of introducing the waste gases with a high concentration of CO2.
The introduction of light into capsules of algae or cyanobacteria has a higher degree of its use, due to lower losses arising from the phenomenon of absorption of light energy by water. As a result of cyclic dosing of gases containing carbon dioxide, the gaseous products of metabolism of algae or cyanobacteria are pushed out and expelled out of the technological system, thus eliminating the negative impact of this factor on binding processes of CO2. The cyclic dosing of the medium having a high concentration of nutrients contributes to the better utilization of the used rinse process permits the systematic removal of excess biomass out of the apparatus.
Obtained in such process technology biomass can be used for various purposes, mainly as feed (fish food, food for zooplankton), fertilizers and energy (a substrate for biogas systems, a source of bio-oil).
The R-Y-D unit is interested in establishing the cooperation in the form of license agreement in order to implement the idea in power or biogas plants sector. The R-Y-D unit would also like to establish a long term research or technical cooperation in case of the possibility of the know-how improvement or development.
Advantages and Innovations:
Application of developed technological solution results in:
- Eliminating large losses of water from the open systems of carbon dioxide biosequestration through evaporation
- Ensuring high concentration of CO2 and bringing light through fiber optics providing high productivity of algal biomass, which directly increases the efficiency of carbon dioxide binding
- Allowing to breed specific algae species e.g. genetically modified, fast-growing, characterized by high efficiency of carbon dioxide biosequestration
- Reducing or completely eliminating the problem of infection, disease or parasites, which limit the amount of algal biomass in the system, and affect directly to lower the effectiveness of carbon dioxide removal from waste gases
- Through the use of fiber optics eliminating of fotobioreactor´s wall fouling process that affects the access of light and thus limit the growth of biomass and CO2 sinks
- Such systems are very versatile and can be used in different climatic conditions
- Developed technological solution is much more resistant to high concentrations of carbon dioxide in the culture medium by reducing the phenomenon of acidification
