SHIP High Temperature

Energy-intensive heavy industries, such as the manufacture of iron, steel, cement, glass or chemicals, require high-temperature processes (> 400°C). In addition to the heat consumed in the low and medium temperature range, 49% of the total industrial heat energy is needed for high temperature processes. Today, these sectors are dominated by the burning of fossil fuels, as there are not many alternatives available. Along with the substitution of fuels by other environmentally friendly fuels, such as hydrogen, the integration of solar heat is a promising option.

Current concentrating solar systems can reach these temperatures, but heat transfer media and storage systems need to be tested for the specific process. The biggest challenge of solar energy integration is to meet the 24/7 continuous energy demand with economic profitability without changing process parameters or product quality.

The industrial sector in Chile appears as the main energy consumer, with 40% of total energy consumption. More than half of the energy consumption is for process heat generation. One third is required for high temperature processes.

Most of the copper, salt and (non-)metal mining mines are located in northern Chile. In addition, there are four cement plants and one steel mill, of which one cement plant is located in the north. Chile is the world's largest copper producer and the richest country in solar energy. With an average DNI of 2920-3650 kWh/m2/year, the integration of solar energy can contribute to the decarbonization of industries and the achievement of sustainability goals for 2030/2050.
