BASF and bse Engineering have signed an exclusive joint development agreement for BASF to provide custom-made catalysts for a new chemical energy storage process.
The companies say that the process will enable the economically-viable transformation of excess current and off-gas carbon dioxide (CO2) into the chemical energy storage methanol in small-scale, delocalized production units.
They say that, when generating current from renewable energy sources such as in wind or solar power plants, excess current is generated at times when consumers do not need it. This excess current can often not be reasonably used at the moment.
The new process developed by bse Engineering enables the sustainable use of current and CO2 with small-scale production units built where the two components are generated, including near power plants using renewable sources of energy as well as large-scale industrial plants producing CO2.
The excess current will be used to produce hydrogen through discontinuous electrolysis. In a second step, methanol is produced from CO2 and hydrogen, thus leading to a valorising of excess current and CO2 off-stream gas.
In the second process step, BASF’s catalysts will be used for methanol synthesis. The catalysts have been further tuned and adapted to enable the most efficient production of methanol. Methanol is one of the most important basic chemicals used in numerous industrial applications. For example, it is blended into diesel or gasoline in some countries.
Adrian Steinmetz, Vice President Chemical Catalysts at BASF, said: “We are pleased to participate in this exciting endeavor and to contribute significantly to a concrete solution for the use of excess current and CO2 as a raw material.
“We will leverage our know-how and expertise in catalysis in the service of advancing a sustainable answer for the transition to new energy sources and the material use of CO2.”
Christian Schweitzer, Managing Director of bse Engineering, said: “The implementation of these projects is ensured with international branch leaders of the respective process units and part-services over a reliable consortium consisting of Aker Solutions ASA, Sulzer Chemtech AG, InfraServ GmbH & Co. Knapsack KG, led by bse Engineering. We are very proud to work on the key technology catalysts with an experienced and innovative industry leader like BASF to make our vision a reality.”
