Leverkusen/Germany – Bayer's new oxygen depolarized cathode (ODC) technology has reached the final round of the competition for the German Industry Innovation Prize,sponsored by the German Federal government. The process, which was developed in collaboration with Thyssen Krupp, reduces the amount of power needed for the very energy-intensive production of the basic chemical chlorine by up to 30 percent, the company states.

First Large Scale Order From China for ODC

The new technology has already attracted customers from china, where a first large-scale order for an ODC plant, with an annual production capacity of 80,000 metric tons, was recently submitted by Befar, a Chinese chemical company.

Bayer sees a huge potential for this technology also in Europe: If all chlorine producers in Germany adopted the technology, which has now reached market maturity, the country's overall energy consumption could be reduced by around one percent, the company believes. That is roughly equivalent to the energy consumed annually by the large city of Cologne. The ODC process could therefore play a key role in Germany’s energy revolution, which is particularly aimed at increasing energy efficiency. This consequently aids climate protection because the energy savings go hand in hand with a CO2 emissions reduction of up to 30 percent.

Chlorine Production Offers Huge Possibilities fo Energy Savings

"The ODC technology can offer ecological and economic benefit because it can increase energy efficiency significantly in a production process that is essential to the chemical industry," stated Hans-Theo Kühr, CEO of the Process Technologies Business Unit of ThyssenKrupp Industrial Solutions. Along with Uhdenora, the company is a development partner of Bayer Material Science for the new process.

The company has submitted its Innovation Prize entry in the "large companies" category and was honored as a finalist for the prestigious award at the official prize ceremony held over the weekend in Frankfurt.

"The Innovation Prize is an event with a long and successful tradition and is the oldest such award in Germany. All major German companies have submitted entries to this prize in recent years," stated Germany's Federal Minister of Education and Research Johanna Wanka in her welcome address. "An award like this one provides impetus and encouragement. We're doing well at the moment. For this to remain so we need further joint efforts."
