Basf has received funding approval from the German Federal Ministry for Economic Affairs and Climate Action for the construction of the world’s most powerful industrial heat pump. In the coming months, the company will therefore be able to start the preparatory construction work for the project at its Ludwigshafen site. The project is intended to make an important contribution to reducing CO2.
The planned heat pump will have a capacity of up to 500,000 metric tons of steam per year. The waste heat, which is used as a thermal energy source, is generated during the cooling and cleaning of process gases in one of the two steam crackers at the site. Powered by electricity from renewable energy, CO2-free steam is thus generated, and most of this steam is to be used in the production of formic acid. Here, the heat pump has the potential to reduce greenhouse gas emissions by up to 98 percent. A smaller proportion of the CO2-free steam is supplied to other BASF production plants via the steam network at the site. In total, the heat pump will reduce greenhouse gas emissions at the company’s headquarters by up to 100,000 metric tons per year.
The plant is scheduled to be commissioned in 2027. The German Federal Ministry for Economic Affairs and Climate Action is contributing up to around 310 million to the project as part of the Carbon Contracts for Difference funding program.
In addition to electricity, steam is one of the most important energy sources in the chemical industry. The Ludwigshafen site primarily uses it as process steam for production – for drying products, heating reactors, and for distillation, among other things. In the past year, BASF used about 14 million metric tons of steam in Ludwigshafen. By means of heat recovery from production facilities, BASF already meets half of the steam requirements at its main site using a low-carbon process. The other roughly 50 percent is currently generated by gas and steam power plants.
The green transformation is one of BASF’s key strategic cornerstones. In addition to using renewable raw materials and electricity from renewable sources, this transformation also includes testing and developing new technologies that reduce the use of fossil raw materials in energy production, thus enabling the manufacture of chemical products with a reduced carbon footprint. Examples of this transformation at the Ludwigshafen site include the water electrolyzer that is currently under construction and the demonstration plant for electrically heated steam crackers, which went into operation in April of this year.
