| News from GERG – The European Gas Research Group Dr. Klaus Altfeld, Dave Pinchbeck Natural gas is and will continue to be a major contributor to the energy requirements and the well-being of Europe for many decades to come. R&D is essential to this and will ensure the continued availability and efficient use of this precious resource and, although the gas industry is mature, it is imperative that it develops the latest technology to be in a position to adapt to new and changing requirements. |
| Long-term gas supply for Europe – Pipeline projects and LNG-chains Prof. Dr. Hans-Georg Fasold The current situation of gas supply is characterized by a temporary global oversupply – caused by the exploration and production of unconventional natural gas in North America combined with declining demand due to the global economic crisis. The worldwide natural gas supply is expected to be secured until 2030 and beyond. |
| Injection of biogas, SNG and hydrogen into the gas grid Dr.-Ing Dipl.-Wirt.-Ing. Frank Graf, Dipl.-Ing. Manuel Götz, Dr.-Ing Siegfried Bajohr Next to wind and hydro power the power generation with biogas as fuel is an emerging technology. Today almost 6000 biomass digesters are in operation in Germany. Alas, only about 10 % of the co-generated heat is used on site. Therefore, upgrading and injection of biogas to the gas grid is a viable alternative in order to improve the overall energy balance of the fermentation based processes. |
| Assessment criteria for local reductions in wall thickness in high-pressure gas pipelines which are in operation Georg HaĂź, Ulrich Hoffmann, JĂĽrgen Konarske, Thorsten Soppa, Dr.-Ing. Michael Steiner Local reductions in wall thickness of high-pressure gas pipelines which are in operation often lead to problems in assessing of integrity, as no clear specifications exist within German regulations. The DVGW commissioned an investigation of the existing procedures dealing with this subject. The results of the investigation are presented. |
| Application of PuraTreat® R+ for the upgrading of biogas Dipl.Ing. Ralf Diez, Friedrich Lampe, Dr.-Ing. Reinhold Rieger, Dipl.-Ing. Christian Riemann An absorbent for the upgrading of biogas was developed on the initiative of WINGAS and in collaboration with BASF, BIS E.M.S. and Wintershall. In a pilot plant the absorbent PuraTreat® R+ was tested under real conditions to make biogas compatible for injection into the natural gas grid. |
| Testing commercially available gas-fired condensing appliances equipped
with a combustion control system Dr. Petra Nitschke-Kowsky, Harald Radtke E.ON Ruhrgas has tested the four commercially available condensing appliances equipped with a combustion control system at its test facility under near-field conditions to assess their operational safety and combustion hygiene when operated with gases in a Wobbe range of 11.5 kWh/mÂł to 16.1 kWh/mÂł and compare them with conventional condensing appliances. |
| AERIUS – Smart Metering in gas consumption measurement Dr.-Ing. Christoph Sosna, Dipl.-Phys. Ing. Manfred Schulze Smart Metering will become increasingly important in the domestic segment in the near future – not only due to legal standards – and offer consumers more billing transparency. |
