BASF presents roadmap to climate neutrality

In 2018, BASF Group’s worldwide emissions amounted to 21.9 million t of CO₂ equivalents. In 1990, this figure was roughly twice as high. The new 2030 emissions goal represents a reduction of approximately 60% compared to 1990 levels, which exceeds the European Union’s target of -55%. “The new climate goals underscore our determination and BASF’s commitment to the Paris Climate Agreement. Climate change is the greatest challenge of the 21st century. In response, we must adapt our processes and our product portfolio. We need to accelerate this transformation now. We must first concentrate on the initial steps of this journey, not the final ones. That is why BASF will increase its use of renewable energies. And we will accelerate the development and deployment of new CO₂-free processes for the production of chemicals. With transparency and offerings to systematically and incrementally reduce the carbon footprint of BASF products throughout the entire value chain, we help our customers in all industries to reduce the carbon footprint of their own products,” said Dr Martin Brudermüller, Chairman of the Board of Executive Directors of BASF SE.

At the heart of the long-term transition toward net zero CO₂ emissions by 2050 is the use of new technologies which will replace fossil fuels, such as natural gas with electricity from renewable sources. Most of these technologies are being pioneered by BASF in collaboration with partners and are currently in a pilot stage. Broad scaleup of these technologies will only be fully realisable after 2030. In order to accelerate the avoidance of CO₂ emissions prior to that date, BASF also continues to systematically implement continuous improvement processes for existing production plants. In addition, BASF will progressively switch to renewable sources to meet its electricity needs and intends to invest in wind parks to facilitate this.

One of the most important new technologies that BASF is currently developing are electrically heated steam crackers for the production of basic chemicals such as ethylene, propylene and butadiene. These chemicals are building blocks for numerous value chains and are essential for chemical production. Hydrogen is another important feedstock for many chemical production processes. To achieve CO₂-free production of hydrogen, BASF is pursuing two processes in parallel: the commercially available water electrolysis and methane pyrolysis, for which BASF has developed a new process technology. Another important lever to increase energy efficiency is the use of electrical heat pumps to produce CO₂-free steam from waste heat. BASF’s goal is to work with Siemens Energy to gradually ramp up this technology to industrial scale and use it for waste heat recovery at entire sites.

BASF expects that this switch to climate-neutral production processes will lead to a sharp increase in electricity demand at the group’s major sites, including the largest production site in Ludwigshafen, in the coming decade. From around 2035, the group’s electricity demand is expected to be more than three times higher than it is today. In addition to the planned investments in renewable energies, BASF is also pursuing a number of specific flagship projects:

1. Together with SABIC and Linde, BASF is working on the realisation of a pilot furnace for the world’s first electrically heated steam cracker. Compared to conventional crackers, this would enable nearly CO₂-free production of basic chemicals. If the necessary funding is granted, start-up of the pilot plant is slated to begin as early as 2023.
2. BASF is developing methane pyrolysis technology for the CO₂-free production of hydrogen from natural gas. Compared to other processes for emission-free hydrogen production, methane pyrolysis requires only around one-fifth as much electrical energy. A pilot reactor has been constructed in Ludwigshafen and is being started up. Funding for this project was provided by the German Federal Ministry of Education and Research.
3. In collaboration with Siemens Energy, BASF is currently investigating possibilities for the construction of a PEM (proton exchange membrane) water electrolysis system with a capacity of 50 MW for CO₂-free production of hydrogen from water and electricity at the Ludwigshafen site. This CO₂-free hydrogen would be primarily used as a raw material in the Verbund but would also be used to a limited extent to support the launch of the mobility market in the Rhine-Neckar metropolitan region.

At the Antwerp site, BASF is planning to invest in one of the largest carbon capture and storage (CCS) projects under the North Sea. Together with partners in the Antwerp@C consortium, this creates the opportunity to avoid more than 1 million tpy of CO₂ emissions from the production of basic chemicals. A final investment decision is targeted for 2022.
