Objectives and work programme
The objective of the FABIG research project is to create the foundations and processes for the application of glass photobioreactors for energy generation. This is intended to contribute to the expansion of renewable energy sources, in order to fulfil the ambitious environmental goals set by the Federal Government. Microalgae are cultivated in panel-shaped bioreactors and draw energy from sunlight to create biomass using carbon dioxide and nutrients such as nitrogen and phosphorus. Light-filled facade areas are well suited for energy generation systems that are integrated into buildings and also offer favourable conditions for the growth of the microorganisms.
Developing photobioreactors made of glass is intended to fulfil multiple objectives. On the one hand, they can be used to extract heat directly from the solar radiation, and on the other hand, the energy can be stored by converting the energy from the sun into biomass. Glass offers a wear-resistant option for the construction material. Moreover, this kind of construction material can be altered, meaning that increasing light transmission will increase the effectiveness of the reactors.
During the course of the research project, a panel-shaped photobioreactor made of glass is to be investigated. This is intended to ensure a cost-effective option thanks to the durability of glass. The focus is to design a glass structure with adhesive bonds, which can improve both effectiveness and longevity. Moreover, systems for integrating the technology into existing facade concepts are to be created, and the interfaces with the building services are to be defined.
Models for describing performance are to be studied, the manufacturing technology is to be further developed, and a suitable, practicable adhesive bonding system is to be determined in order to lay the foundations for market introduction.
