Disponible en CD en formato PDF Transcripción del abstract original del autor: The Lined Rock Cavern (LRC) concept is a new technology for underground storage of natural gas. The main principle is to store gas at high pressures in lined rock caverns at relatively shallow depths. The rock absorbs the pressure load and the lining ensures gas tightness. Included in the concept is a system for circulation heating or cooling of the gas to improve the working gas amount and lower the specific storage cost. The LRC Demo Project (joint-venture between Gaz de France and Sydkraft) aims at demonstrating the technology by constructing a demonstration storage plant situated near the coastal city of Halmstad in southwestern Sweden. Construction works started in the end of 1998 and was finished mid 2002. The cavern has since then been subjected to an extensive scientific testing programme, including loading of the cavern up to 22 MPa. The preliminary evaluation indicates that the deformation level in general is well below the design limits. Commercial operation of the LRC Demo Plant will start during year 2003. The LRC concept has now emerged as an existing commercial technology and is ready to challenge other existing storage alternatives on the market. The main advantages of the LRC technology are: great freedom of localisation with respect to geology, high deliverability and turnover rates, no gas treatment, low impact on landscape and environment and a possibility to expand a storage plant in steps by adding storage cavern modules.
