Wärtsilä has been awarded an Operations and Maintenance (O&M) contract by the Al Badia Cement JSC for its captive power plant. The plant is located within the company’s cement factory grounds in the Abu Al Shamat area, in Syria. The contract is valid for three years.
The power plant will be the sole source of electrical supply to this new cement works facility, and is currently in the process of being commissioned for operation. It is powered by five Wärtsilä 20V32 and one Wärtsilä 9L32 generating sets, and produces a total output of more than 45 MW. The plant is also fitted with exhaust gas fired boilers for its auxiliary heating system.
Under the terms of the agreement, Wärtsilä will take responsibility for operating and maintaining the power plant so that it runs cost-effectively and with optimal efficiency. In this way the customer is able to focus entirely on the company’s core business of producing 1.60 million tons of cement annually in the first line.
From 16 to 19 November, at the BioEnergy Decentral exhibition in Hanover, Tognum subsidiary MTU Onsite Energy GmbH Gas Power Systems was showcasing electric power generation sets and combined heat and power (CHP) modules with the new Series 4000 biogas engines for the first time. With an electrical output of up to 2MW, these units complete the biogas product portfolio at the top end of the range.
These more powerful engines mean that operators of larger biogas plants can achieve even greater cost efficiency because, among other benefits, service and maintenance costs can be reduced in comparison with plants based on smaller engines and because superior power density reduces space requirements. Market introduction of biogas power generation plants based on 8, 12, 16 and 20-cylinder engines covering an output range from around 770kW to 2,000kW will take place in stages from March 2011. In addition, plants based on CHP modules provide access to an extra 2.6MW of thermal energy. Plans are also underway to introduce other versions during the course of next year. These include sewage and landfill gas with other versions for special gases scheduled for later.
Siemens Energy has successfully completed the first test phase with its CO2 capture process in a pilot facility at the Staudinger power plant operated by E.ON. With its innovative and particularly ecofriendly process the company is setting new benchmarks in CO2 capture in fossil-fueled power plants. Process efficiency, the long-term chemical stability of the scrubbing agent and emissions were investigated in the pilot facility under real power plant conditions. After over 3,000 operating hours since commissioning of the facility in September 2009, it has been demonstrated that the post-combustion capture process developed by Siemens (PostCap) attains a CO2 capture efficiency of over 90 percent with practically zero solvent emissions. The energy consumption is significantly lower than comparable conventional processes.
 Iberdrola Renovables, the world’s leading wind energy company, continues to bolster its presence in the US with the construction of new wind farms.
Work has just began on the Star Point facility in Oregon which will have installed capacity of 98.7 MW. This farm is in addition to others the company has begun building in recent months: Rugby (North Dakota), with 149 MW; and Cayuga Ridge (Illinois), with 300 MW.
This will give Iberdrola Renovables a total of 547.7 MW under construction in the US. Once operational, these wind farms could avoid the emission of 180.000 tonnes of C02 and supply electricity to some 250,000 average US households a year.
Last week Iberdrola Renovables dedicated the Lempster facility in New Hampshire with installed capacity of 24 MW and which will be able to supply electricity to some 10,000 US households a year.
The company, which is present in 20 states, has 34 wind farms in operation in the country. At 31 March, installed capacity in the US totalled 3,031 MW, 31.4% of the group’s total (9,624 MW).
The US represents one of the main markets for Iberdrola Renovables and is where a large part of its growth is concentrated. Forty-two percent of the company’s project pipeline –the largest in the world with close to 56,000 MW(2), is located there. The company employs more than 800 people in the US.
The Obama administration’s support for renewable energies is one of keys to the sector’s future growth in the country. In addition to the new measures approved as part of the economic stimulus package (which will help financing for projects, among other issues), Congress is expected to pass a new energy act which could include obligatory nationwide renewable portfolio standards.
 Mitsubishi Heavy Industries, Ltd. (MHI) and Mitsubishi Corporation (MC) have agreed with ZeroGen Pty. Ltd. of Australia to participate in the project to build a low-emission integrated gasification combined cycle (IGCC) power generation plant integrated with a carbon capture and storage (CCS) facility, and jointly received an order to implement a feasibility study (F/S) on the project. This will be the world's first commercial-scale IGCC power plant with CCS capability, producing 530 megawatts (MW) of electricity and capturing carbon dioxide (CO2) emissions. The plant is slated to go on-stream in 2015.
The ZeroGen project combines a high-efficiency IGCC plant that will generate power using fuel produced through gasification of coal, which is abundant in Australia, and CCS technology, which captures and sequesters CO2 in deep subsurface brine aquifers. The power plant will be built in Queensland, with MHI serving as the exclusive manufacturer, supplier and builder of the IGCC facility, including CO2 recovery and storage systems. MC will coordinate the overall project. ZeroGen, which is wholly owned by the Queensland State Government, will be the project implementation body. In that capacity it will be responsible for the selection of potential sites in Queensland both for the IGCC plant and for a carbon transport and storage area, and will also handle other crucial areas such as infrastructure, coal supply, stakeholder engagement and environmental studies.
For its fuel, the IGCC power generation system uses gas produced by gasification of fine milled coal in a gasification furnace. Electricity is generated by gas-turbine and steam-turbine combined cycle. IGCC delivers higher power generation efficiency than conventional coal-fired power plants and lower emissions of not only CO2 but also SOx, NOx and soot.
In the ZeroGen project, CO2 will be recovered from gas before combustion by gas turbine. In the coal-gasification process, carbon monoxide (CO) and hydrogen gases are produced through oxygen reaction of coal, then CO2 is separated and recovered through the shift reaction of CO and steam.
Siemens Energy has received an order from its Indian licensee Bharat Heavy Electricals Ltd. (BHEL) for the supply of key components for a 1,600-megawatt (MW) coal-fired power plant in India. Delivery of the components is scheduled for late 2011. The order volume amounts to over EUR80 million.
The Siemens scope of supply essentially comprises an SST5-6000 steam turbine, a water-cooled SGen5-3000W generator, an SPPA-T3000 instrumentation & controls system for the turbine-generators, and components for the second turbine-generator.
Coal is India’s most important source of energy. Against the backdrop of climate change cost-effective and climate-compatible coal-based power generation is of decisive importance. “High efficiency levels can be attained with our supercritical steam turbines, which operate at parameters of 580 degree C and 250 bar,” said Fischer. Each percentage point increase in efficiency in a medium-capacity coal-fired power plant brings annual CO2 savings amounting to approximately 80,000 metric tons. That is comparable with the CO2 emissions from around 20,000 mid-range automobiles, each clocking up 20,000 kilometers a year.
The Volvo Group and DEUTZ AG concluded a co-operation agreement in 1998 concerning the development and supply of diesel engines with 4-7 litre displacement for non-automotive and automotive applications. Since then the DEUTZ products have strongly contributed to the successful growth of Volvo’s Medium duty Engine Platform. The agreement has a term of 15 years and it expires at the end of the year 2013.
Although the agreement is set to remain unchanged for the next 4 years, both companies have already now started negotiations on products, volumes and terms for the continuation of their partnership in the period beginning in 2014.
Catalysts for the early start of the negotiations are the long development times for the next exhaust gas emission stages for industrial engines and the decision of Volvo to develop their own automotive engine for the next emission stage Euro 6.
Common projects for industrial engines with the exhaust gas ratings COM II, III A, III B and IV (EPA 2, 3, 4 interim and 4 final) and automotive engines with the exhaust gas ratings Euro 3, 4 and 5 are not affected by this decision and both partners are targeting to further increase sales of engines with 4-7 litre displacement in these segments.
DEUTZ requires its own development resources for the business expansion in the compact engine range up to 4 litre displacement, where two entirely new engine series are developed for the next exhaust emission stages in the off-road segment.
