Procedure of the replacement of fossil fuels for thermal heat supply by regional renewable energies exemplary for textile companies in Indonesia

The research project EnaTex (2021 - 2024) is funded within the "CLIENT II Program – International Partnerships for Sustainable Innovation" of the German Federal Ministry of Education and Research (BMBF). A major aim is the development and demonstration of innovative approaches for energy savings and renewable energies based on local and regional sources for selected production sites of the Indonesian textile industry. For biomass the focus is on local residual biomasses as energy sources as well as technologies to process those biomasses to thermal energy. The thermal energy is currently generated by 100% with hard and converted to steam and heated thermal-oil as energy carrier. The energy is mainly applied for drying and washing machines the finishing process with focus on dyeing, printing and application of functions of textiles. The electricity is supplied by the national grid operator PLN and mainly used to power motors and electronics as well as to provide illumination and air condition. Here Photovoltaic systems are being investigated to substitute power from the national grid, which is mainly supplied by hard coal fired power plants. The speech will state the technical and legal challenges of the defossilization of the energy supply in the Indonesian Textile Industry.
