Jenbacher Gas Engines in Coca-Cola Hellenic plants
Coca-Cola Hellenic to Install GE Energy’s Jenbacher Gas Engines In European Bottling Plants To Help Reduce Plant CO2 Emissions by More Than 20% Across Their Production
The Coca-Cola Hellenic Bottling Company S.A. and energy development company ContourGlobal, are launching a major industrial emissions reduction initiative in Europe with plans to install a total of 15 CHP (Combined Heat and Power) plants at bottling facilities in twelve countries. The first phase of the project will utilize 19 GE Energy Jenbacher gas engines with a total output of 58 MW. This supports the European Commission’s goal to adopt more stringent environmental targets for member countries to help Europe achieve a 20% reduction in emissions by 2020. Each bottling plant utilizing the Jenbacher engines will be able to eliminate more than 40% of their annual carbon dioxide (CO2) emissions.
“As the European Commission seeks to further reduce the region’s emissions, we are extremely excited to offer our customers technology that provides energy efficient, on-site power and helps reduce the carbon footprint in their operations,” said Prady Iyyanki, CEO of GE Energy’s Jenbacher gas engine business.
GE is supplying the Jenbacher gas engine cogeneration units to ContourGlobal, which will install the systems at various Coca-Cola Hellenic Bottling Company’s sites. Coca Cola is planning to install CHP units in Austria, Czech Republic, Greece, Italy, Northern Ireland, Poland, Romania, Slovakia, Russia, Ukraine, Serbia, and Nigeria. Two installations will be built in each of Italy, Russia and Romania.
Fueled by natural gas, GE’s Jenbacher units will generate electricity to meet Coca-Cola’s need for a reliable source of on-site power. The systems will also provide heat and cooling.
Cogeneration, also known as combined heat and power or “CHP,” is inherently more energy efficient than using separate power and heat generating sources, making it an effective anti-pollution strategy. As a result, the EU in recent years has begun urging countries to begin modernizing their industrial and municipal cogeneration systems in order to help improve energy efficiency and curtail their emission levels.
Under its contract with ContourGlobal, GE is providing Jenbacher JMS 620 GS-N.L systems, including heat recovery from jacket water, intercooler and oil, as well as its DIA.NE XT control system for the units.
GE’s Jenbacher engines will be delivered end of 2008 and 2009, with commissioning scheduled as the plants are ready. The equipment is being built at GE’s gas engine manufacturing center in Jenbach, Austria.
About Combined Heat and Power (CHP)
According to Combined Heat and Power Association (www.chpa.co.uk) definition, Combined Heat and Power (CHP) is the simultaneous generation of usable heat and power (usually electricity) in a single process. Through the use of an absorption cooling cycle, trigeneration or Combined Cooling Heat and Power (CCHP) schemes can also be developed. CHP is a highly efficient way to use both fossil and renewable fuels and can therefore make a significant contribution to the UK’s sustainable energy goals, bringing environmental, economic, social and energy security benefits.
CHP systems can be employed over a wide range of sizes, applications, fuels and technologies. In its simplest form, it employs a gas turbine, an engine or a steam turbine to drive an alternator, and the resulting electricity can be used either wholly or partially on-site. The heat produced during power generation is recovered, usually in a heat recovery boiler and can be used to raise steam for a number of industrial processes, to provide hot water for space heating, or, as mentioned above with appropriate equipment installed, cooling.
Because CHP systems make extensive use of the heat produced during the electricity generation process, they can achieve overall efficiencies in excess of 70% at the point of use. In contrast, the efficiency of conventional coal-fired and gas-fired power stations, which discard this heat, is typically around 38% and 48% respectively, at the power station. Efficiency at the point of use is lower still because of the losses that occur during transmission and distribution. (see DUKES electricity chapter for more details)
In contrast, CHP is a form of a decentralised energy technology. CHP systems are typically installed onsite, supplying customers with heat and power directly at the point of use, therefore helping avoid the significant losses (which occur in transmitting electricity from large centralised plant to customer.
