NISSEN energy
About
NISSEN energy is a Danish energy systems integrator headquartered in Skanderborg, Denmark, with a US office in Chicago, Illinois. Led by CEO Michael B. Nissen, the company designs, manufactures, and services biogas energy systems with 24/7/365 support from both locations. Their core offering centers on gas engine combined heat and power (CHP) plants ranging from 64 kW to 2,500 kW electrical output, built on MAN and MTU Rolls-Royce engine platforms. The NISSEN PowerHouse is a containerized, turnkey CHP solution delivered fully assembled for on-site installation without dedicated building construction. On the gas upgrading side, NISSEN energy deploys EVONIK's SEPURAN Green membrane technology, achieving methane yields above 99.5% without process water or chemicals. Their gas cleaning division produces custom pretreatment systems that combine gas cooling with activated carbon filtration to strip water, siloxanes, and hydrogen sulfide from raw biogas. The company also distributes Zantingh gas burners and boilers across Scandinavia, Germany, and England, and offers the Nordic region's widest gas flare portfolio through partnerships with leading European suppliers. NISSEN energy holds ISO 9001:2015 certification and delivers turnkey installations from planning through commissioning, supported by comprehensive after-sales service and spare parts logistics.
