The authors believe the Foreword Despite major global challenges, we have seen substantial progress in the energy transition inGermany and China in the last years. China remains the country with the world’s largest in-stalled capacity of renewable energy, whereas in Germany, the share of renewables in the netelectricity generation has exceeded 50% for the first time. But whilst the promotion and de- As part of its energy transition, the German Federal Government has set itself the target to reachclimate-neutrality in all sectors by 2045. By mid-century, Germany aims to cut its primary en-ergy consumption by 50% compared to 2008. To achieve this, Germany adopted the “efficiency In a similar vein, China has emphasised energy efficiency as part of its Energy Revolution Strat-egy (2016– 2030). The 14th Five-Year-Plan set forth by the Chinese government aims to reduceenergy intensity by 13.5% and carbon intensity by 18% over the 2021-2025 period. These targets Martin Hofmann The glass fibre industry is an energy-intensive sector, its unit energy consumption ranging be-tween 7.2 to 12.6 GJ per tonne of glass product. A variety of measures – from glass recycling tousing green hydrogen, heat recovery and electrification – are available for reducing fossil fuelconsumption and carbon dioxide emissions in the sector. Notably, 15-25% of the overall CO2 Here, international cooperation between Germany and China can play a contributing role. Thisreport is published as part of the Sino-German Energy Partnership between the German Fed-eral Ministry for Economic Affairs and Climate Action (BMWK), the National Development and The report is the fourth in a series of reports on energy efficiency measures in heavy industrysectors. It highlights process-related measures in the very energy-intensive process of glass I would like to express my gratitude to all involved experts and implementing partners, espe-cially the National Energy Conservation Center of China (NECC) and the Jiangsu Department Content 3.1Description of the Production Process and Process Steps3.2Current Situation and Development of Energy Efficiency in the Sector3.2.1Energy Statistics and Benchmarks Glass (Fibre) Sector3.2.2Energy and Material Flows 4.7Low Carbon Fuels 4.7.1Description of Baseline Situation and Energy Consumption4.7.2Suggested Measures of Improvement4.7.3Potential Energy Savings and Greenhouse Gas Emission Reduction 4.8Model Based Predictive Control (MBPC)4.8.1Description of Baseline Situation and Energy Consumption4.8.2Suggested Measures of Improvement4.8.3Potential Energy Savings and Greenhouse Gas Emission Reduction4.9Pressure Drop Minimization4.9.1Description of Baseline Situation and Energy Consumption4.9.2Suggested Measures of Improvement List of Figures Figure 1: Energy Saving Potentials of Selected Measures (kWh/t)11Figure 2: Net CO2 Saving (kg CO2/t) Potentials of Selected Measures11Figure 3: TFC Shares: Top left EU, Top right World, Bottom China13Figure 4: TFC Shares / Industry14Figure 5: ODEX Indicator- Industrial Sectors European Union15Figure 6: ODEX Indicator- Industrial Sectors Germany15Figure 7: Components of Glass Furnace21Figure 8: Forming Methods for Glass Fibres22Figure 9: Production Shares (%) of Glass Production Sub-Sectors in Europe23Figure 10: Unit Energy Consumption (GJ/tonne) of Different Glass Types, (Leisin, 2019)25 List of Tables Table 1: Glass Production in Europe in Tonnes (EU 28, excluding insulation glass fibres, 2020)23Table 2: Contin
