Bioethanol

Since mid-2008, we have been operating in Stade one of the largest plants for the production of bioethanol in Germany. By utilizing future-oriented technology, we meet the future requirements regarding energy saving and quality already today. The location in Stade particularly offers logistical advantages. The procurement of raw materials (wheat) as well as the marketing of end products is conducted by sea, rail and road. By recombining the process steps while focusing on energy and cost efficiency we have been able to realize a concept enabling energy savings of 43% compared with conventional methods. Furthermore, synergetic advantages have resulted from the RDF power plant planned nearby. Total investment has been approx. 71 million Euros. The output is 300,000 litres of bioethanol (99.9 %) per day with an annual capacity of up to 120,000 m³. Additionally, high quality by-products are produced for the food and feed industry.
Iron Casting

Since there is little capacity for the serial production of large cast parts for offshore wind energy converters in Germany, PN Casting Technology GmbH was commissioned in 2009. In 2010, the production was gradually ramped up. A frame supply contract has been concluded with Areva Wind with an annual turnover of 137 million € until 2013. Complex cast parts have also been supplied to Siemens AG (engineering and construction division). Preparing a substantial expansion of supply volumes, negotiations on a frame supply contract are close to being concluded. Furthermore, high volume supply contracts with the wind energy division of the Siemens group are currently being negotiated.
Jack-up barge

PN Upstalsboom GmbH & Co. KG, a 100 % subsidiary of N.prior energy GmbH, is planning to construct a self-elevating platform especially for the installation of large wind energy converters at sea: a jack-up barge. Unique characteristics are the dimensions of the crane, the capacity and the available space on board as well as the independence from weather conditions. It contributes significantly to a cost effective installation of offshore wind energy converters. Commissioning is planned for 2012. The company cooperates with a large internationally operating construction group and is responsible for the provision of the jack-up barge as well as for engineering, planning and the approval procedure.
