German pharmaceutical, chemical and life science giant, Bayer, greatly appreciates the role combined heat and power is playing in facilitating its operations.

Currenta, a 60/40 joint venture of Bayer and LANXESS, manages and operates the company’s Chempark with its three sites at the Lower Rhine in Leverkusen, Dormagen and Krefeld-Uerdingen.

The 480-hectare Leverkusen site hosts the manufacture of over 5,000 chemicals, mainly nitration and chlorination products, aromatics, fine chemicals and silicon chemicals. Around 30,616 people work at the campus.

Mauritz Faenger-Montag (right), CHEMPARK Spokesperson told Decentralized Energy just why CHP has become such an integral aspect to their business.

“It supports the goals of the energy transition, or Energiewende and secures the efficient generation at our sites. We operate these highly efficient CHP units to supply the production plants with both electricity and steam and the technology perfectly suits the high, steady, and local demand of steam featuring the chemical industry.”

The power generation focuses on an optimal output of steam while surplus electricity is fed into the public grid, Faenger-Montag adds. With the BDEW this week pointing out a potential energy security issue in Germany on the horizon that role for cogeneration as a back-up is an important one.

“CHP has gained additional importance through the ambitious upgrade of solar and wind power: As long as industry-scale storage capacities are not available, conventional CHP plants are the best backup for the outage of the renewables.”

In that context, Faneger-Montag says more enlightened regulation would encourage the company to increase its efforts in developing CHP further.

“One essential requirement for the further upgrade of CHP units at out sites is the exemption of own usage electricity from the renewable energy surcharge (“EEG-Umlage”). Right now, uncertainties in national energy regulation prevent a state-of-the-art gas and steam turbine power plant at our Krefeld-Uerdingen site from realization.”

The company generally thinks green in terms of resources around its facilities.

Bayer’s greenhouses are on automatic systems that control the amount of light used. They also use what’s called “invisible glass” to allow 98 percent of natural sunlight through, thus using natural energy to supplement controlled artificial lighting.

Greenhouse facilities come with a rainwater collection system, sensored lighting, daylight harvesting and reflective roofing.
