18 BIOGAS ENGINES
New biogas genset for flexible power & heat production in Schleswig-Holstein
Norbert Hack is an energy supplier whose biogas plant provides 50 inhabitants of Wentorf with heat for heating and hot water, thanks to 180 dairy cows kept in fields on farm in Wentorf, Schleswig-Holstein, close to Hamburg. WIP has the story
MWM TCG 3016 gas genset, farmer Norbert Hack intends to deliver the heat that he generates from his biogas to additional households and companies in the region, reliably and efficiently. “My engine dealer

recommended purchasing the new MWM TCG 3016 genset to expand my heat network” says Norbert Hack. Previously, he had already been an MWM customer by way of a dealer. By purchasing the engine, he took up direct contact with the Mannheim-based company. The new MWM TCG 3016
genset makes Norbert Hack‘s biogas plant in Wentorf even more efficient and flexible. “I‘ve been running the TCG
hanks to his investment in a new cogeneration plant and a new
3016 for a few months. As far as I’m concerned, this is the most efficient engine currently available on the market. Compared to its output, its
biogas consumption is said to be ‘astonishingly low’. The engine is perfectly tuned
to his needs and runs very quietly. He has already seen many other gensets and models at his colleagues‘ facili- ties, but “this engine‘s quality is truly outstanding – a genuine trendsetter”, he feels. The new TPEM (Total Plant &
Energy Management) control which Caterpillar Energy Solutions has developed specifically for the MWM gensets is also installed in his cogeneration plant. “The new development from
Mannheim will doubtlessly make the interaction between the control and the engine

even more effective. The TPEM offers more possibilities for reading out engine data, which will further improve the plant operation”, he says. Norbert Hack checks his
biogas plant parameters twice a day and is thus able to react speedily in the event of deviations. With his new plant, he can react even more flexibly to the increasing or declining demand of his customers. “In addition to the TCG 3016,
I also have a smaller MWM genset. Due to the reduced temperature of the lubricant during operation, the oil lasts longer and the oil change intervals have been stretched – all of this saves cash!” He believes that the
company in Mannheim has taken the right direction in the development of the new MWM TCG 3016, making the already
very efficient gensets even more robust. Hack spent about €500,000
on the construction of the new cogeneration plant with transformer and a new heat buffer storage unit. “When I modernize, I do it properly”, he says. Each of his two cogenera- tion plants has its own gas train, consisting of a cooling, scrubbing, and compression unit. This gives him more oper- ating security, as both gensets can operate independently. The biogas plant runs on a 50/50 mix of cattle manure from his own dairy cows andcorn grown on his own fields. The digestate from the
biogas production is spread out on his fields as fertilizer. Any excess quantities are sold. “In this way, the cycle is closed,” he explains.
