BASF & MAN Energy Solutions have entered into a strategic partnership to pursue the construction of an industrial-scale heat pump at the BASF site in Ludwigshafen. This project is intended to make an important contribution to reducing greenhouse gas emissions, establishing the use of low-CO2 technologies in chemical production and reducing the site’s natural gas consumption. As a first step, the project partners are conducting a feasibility study that is expected to be completed by the end of 2022.The planned large-scale heat pump will enable production of steam using electricity from renewable energy, tapping waste heat from the cooling water system at BASF as a source of thermal energy. The residual heat in the water will be processed using compression to produce steam that will be fed into the site’s steam network. By integrating the planned heat pump into the site’s production infrastructure, up to 150 metric tons of steam can be produced per hour, equivalent to a thermal output of 120 megawatts. The project could reduce CO2 emissions at the site by up to 390,000 metric tons per year. At the same time, it would make the cooling water system more efficient and less dependent on climate and weather conditions.Steam is the most important source of energy in the chemical industry. In Ludwigshafen, BASF requires around 20 million metric tons of steam per year. The plants at the site use much of this as process steam in production, for example, to dry products, heat up reactors or for distilling. Around half of the steam required at the Ludwigshafen site is already produced by recovering heat from production facilities using a low-CO2 process. The remaining steam demand, approximately 50 percent, is met by gas and steam power plants, which emit CO2 during generation.
