26/27 CO ² EMISSIONS TRADING. Emissions trading was introduced in the European Union as of january 1, 2005, as part of the implementation of the Kyoto Protocol. The goal of this system is to reduce CO ² emissions where it is cheapest to do so. Market players are facilities that produce emissions and have an output of more than 20 megawatts capacity, energy-intensive industries and – as of 2012 – aviation. The second period of emissions trading in the European Union commenced on january 1, 2008, and will last until 2012. The companies involved are currently preparing for the 3rd trading period which will last from 2013 to 2020 and involve major changes. As of 2013, the emissions trading system will be extended to other sectors and applied more stringently. In future, emissions rights will be auctioned to a greater extent and no longer distributed free of charge as is currently the case. The share of auctioned certificates will increase from 20 percent per annum in 2013 to 70 percent by 2020. In addition, the total quantity of available certificates will be reduced continuously by 21 percent overall. Eleven plants at Wintershall/WINGAS are subject to the statutory requirements for emissions trading in the 2nd trading period from 2008 to 2012. They include compressor stations, the Rehden natural gas storage facility and the steam flooding plant in Emlichheim. Greenhouse gas emissions have already been reduced as a result of numerous projects aimed at improving energy efficiency. Wintershall is also involved in research projects investigating ways of storing and processing CO ² . Compressor station Mallnow in Germany
INSIGHTS. NO FLARING POLICY 2012. The flaring of associated gas not only destroys valuable energy resources worldwide, but also emits huge quantities of greenhouse gases into the atmosphere. To reflect our responsibility for the environment, we are committed to stopping flaring associated gas as part of routine operations. Flaring of it will be discontinued at our existing facilities by 2012, while new plants will be constructed to enable use of the associated gas. As a result, we will play our part as a company dedicated to sustainable production and will also set international standards. We are regarded as a technological leader in Libya when it comes to environmental protection: The gas from the production of crude oil is already completely processed. The quantities of crude oil and associated gas are processed at the central facilities at the Nakhla and As Sarah fields. Following integration of the Hamid field in December 2006, flaring was finally ceased in Libya. STEAM FLOODING TECHNOLOGY. The crude oil at Wintershall’s Emlichheim site in Germany is especially viscous and hence difficult to extract, which is why the company uses a special technique. Water vapor at a temperature of 300 degrees is forced into the reservoir at high pressure using steam flooding. The crude oil trapped in the rock heats up and becomes less viscous, enabling it to flow through the reservoir to the production wells more easily. Associated gas and natural gas are used to produce the steam. Thanks to the use of tempered and desalinated production water as boiler feed water, fuel consumption and the specific greenhouse gas emissions are reduced. EFFICIENT POWER GENERATION. Wintershall already supplies all its operations in Germany independently with electricity it generates itself. The largest of the facilities which help to supply the various sites is the combined heat and power generation (CHP) plant in Emlichheim. Gas that could not previously be used cost-effectively is now used to produce electricity and steam. The heart of the plant is a 5.2-megawatt gas turbine that drives a generator which produces up to 45 million kilowatt hours of electricity per year. Wintershall invested 5.9 million euros in building the new CHP plant. The exhaust heat, which has a temperature of more than 500° C and comes from the gas burned to produce the electricity, would normally be lost in conventional plants, but is used here to produce more than 100,000 tonnes of water vapor a year. Wintershall needs that to extract oil by steam flooding. The new technology cuts CO ² emissions by 25,000 tonnes a year. STEAM TURBINE USES ExHAUST HEAT. The exhaust heat from the three existing gas turbines at the Mallnow natural-gas compressor station near Frankfurt (Oder) is used to power a steam turbine. A pipe with a diameter of around four meters takes the exhaust gases of the gas turbines to a process, where steam is produced to drive the fourth turbine. Afterwards, the used steam is cooled and liquefied in a closed cycle. The steam turbine generates an output of up to 20 megawatts. Expensive drive power is therefore saved and CO ² emissions are specifically reduced. HEALTH SAFETY ENVIRONMENT
