GE Energy and energy developer ECOS Ltd. have announced they plan to demonstrate an innovative, industrial waste-heat recovery system that will dramatically increase the efficiency and output of a 7.2 MW biogas power plant in the eastern Slovenia town of Lendava, near the border with Hungary.
GE’s new pilot Organic Rankine Cycle (ORC) waste-heat recovery system for gas engines is designed to make onsite power plants that use natural gas, landfill gas and other waste gases more cost-attractive to build as countries install more cogeneration and renewable energy capacity to enhance energy security and lower regional emissions.
GE’s new ORC system will allow ECOS to capture more waste heat created by its 7.2 MW Bioplinarna Lendava biogas plant. The extra thermal power will be used to produce steam, which in turn will help generate enough electricity to support 300 European homes without using additional fuel.
The pilot ORC system will be installed on one of the three GE ecomagination-certified Jenbacher J420 biogas engines that have powered ECOS’ Bioplinarna Lendava plant since June 2008. The ORC technology will boost the Jenbacher unit’s electrical efficiency by an estimated five percentage points.
Landfill gas and other renewable biogas projects are among the prime candidates for ORC systems, especially in countries—including those in Europe—that offer high electricity feed-in tariffs.
GE’s new gas engine-ORC technology is a milestone for the global energy industry because for the first time, all of the waste heat from an engine’s exhaust gas and cooling cycle can be fully captured and utilized to drive the power plant’s enhanced steam-creation process.
The new technology was developed by GE’s Munich corporate research center and GE Energy’s Jenbacher gas engine business in Austria.


Alstom has signed an engineering, procurement and construction (EPC) contract with StatoilHydro on behalf of the partners of the European CO2 Technology Centre Mongstad (TCM) for a chilled ammonia (carbonate) CO2 capture plant at TCM in Norway.
The demonstration plant will be the first one of its kind to treat flue gas from a gas-fired power plant.
Alstom will supply and install the demonstration plant, due to be operational in November 2011, which will use the company’s chilled ammonia post-combustion technology to capture CO2 from the flue gases of a combined heat and power plant at Mongstad. It will also treat flue gases from a petroleum processing plant at the nearby Mongstad refinery, which has a CO2 output equal to that of a coal-fired power plant. The test results will consequently be of relevance to both gas- and coal-fired power plants.
The TCM facility at Mongstad is the largest planned demonstration facility of its kind with an annual capacity to capture of up to 100,000 metric tonnes of CO2, of which Alstom’s chilled ammonia technology will have the capacity to capture 80,000 metric tonnes per year, the equivalent of 40 MWt, or equivalent to the annual C02 emissions of approximately 33,000 cars.
The CO2 demonstration project is particularly significant given the importance of Norway’s role as a gas exporter. Norway is the second largest exporter of gas to the EU after Russia, supplying more than 15% of the European gas market.
Alstom is at the forefront of carbon capture technology development. In recent months, as part of its multi-product strategy, the company has announced agreements with AEP, The Dow Chemical Company, E.ON, PGE Elektrownia, StatoilHydro, Total, TransAlta, Vattenfall and We Energies to test CO2 capture technologies in Europe and North America. To date, Alstom has started operation at several CO2 capture pilot projects, including projects with We Energies in the USA, E.ON in Sweden and Vattenfall in Germany.


In a follow-up project, the long-established Mannheim-based company MWM recently received an order for another gas genset. The customer is Helsinki Water, an enterprise of Finland's capital Helsinki that looks back on 130 years of experience and expertise in wastewater management.
The supplied engine of the TCG 2020 series with twelve cylinders delivers an electrical output of approximately 1,000 kWel, with an efficiency of 41.3%.
The central wastewater treatment plant Viikinmäki for the city Helsinki and adjacent communities was commissioned back in 1994 with four engines from MWM, three gas engines and one gas/diesel engine. The plant processes the wastewater of about 780,000 inhabitants (accounts for 85% of the volume) and of industrial plants (15%), which adds up to 3.53 billion cubic feet a year. The fermentation in the purification process generates about 353 million cubit feet of sewage gas a year, which is used for the generation of electrical and thermal energy, covering 100% of the plant's need for heat and about 50% of the power needs. So far, the MWM gensets have been producing 16 GWh of eco-friendly electricity and about 26 GWh of eco-friendly heat a year.
The on-site implementation of the project was taken care of by the Finnish company Sarlin, with which MWM has already been working successfully for quite some time. This partner is also responsible for the handling of the ongoing maintenance agreements. In 2008, the two companies jointly won all tenders in Finland.


Centrax have won an order to supply Oil and Gas company, Wintershall Holding AG, with a CX501-KB7 generator set.
Wintershall are a wholly owned subsidiary of BASF. The company has been active in the exploration and production of oil and gas for more than 75 years. It is now Germany's largest producer of crude oil and natural gas.
The generator set will be installed in the steam production plant of the Wintershall oilfield Emlichheim which is located in North West Germany close to the Dutch border.
The KB7 DLE package had to meet strict NACE oil and gas standards and will produce 5.2 MW of electricity for the site, with the exhaust ducted to a waste heat recovery boiler to generate high pressure steam. The steam is injected underground to help reduce the viscosity of the oil to aid the oil extraction process.
The crude oil in Emlichheim is very viscous and firmly embedded in the rock pores and to extract it, steam flooding technology is used. During this process, steam with a temperature of approximately 300 degrees, is forced underground at a pressure of approximately 100 bar. The crude oil in the porous rock becomes warm and less viscous and is easier to pump to the surface.
Wintershall have been harnessing steam flooding technology in Emlichheim for more  than 25 years and has thus continuously maintained the high production level of about 140,000 tons of crude oil per year.
The Centrax package will be installed and running towards the end of 2009 .
