Green electricity for a CO2-neutral chemical industry and green hydrogen

The RWE-BASF lighthouse project “Offshore-to-X” aims to accelerate the transition to a CO2-free chemical industry – by electrifying production processes that were previously based on fossil fuels and through CO2-free hydrogen. The idea: BASF replaces CO2-intensive processes for basic chemical production at its Ludwigshafen site with innovative CO2-free technologies. The green electricity needed for this will be produced by RWE and BASF in an offshore wind park, to be built in the German North Sea in addition to the new installations foreseen by existing policy. With the remaining electricity, RWE will produce green hydrogen using electrolysis.  

A brief overview of the key components of the plan:

  1. Offshore wind park in the North Sea

    • Capacity: 2 GW in addition to the previously planned capacity expansion, to produce around 7,500 GWh of green electricity per year
    • Tender for the wind park should be in addition to the planned 20 GW by 2030 in existing legislation. The green electricity would therefore meet the criterion of additionality. Tender should be aimed at the transformation of the chemical industry.  
    • The potential offshore sites for this project are ones that are currently only planned for the period after 2030 according to Germany’s Site Development Plan and Network Development Plan. 
    • Network connection to mainland in Lower Saxony: Via the grid of the transmission system operator (TSO), electricity can be transported to Ludwigshafen and to the future site of the electrolysis project for green hydrogen; various options due to existing RWE sites in northwestern Germany.
    • RWE will develop, build and operate the wind park.
    • BASF will own a stake.
