Carbon capture reduces the efficiency of the combined-cycle gas turbine power plant (CCGT) by 11%-point, a study by Sari Siitonen, Gasum Oy and Leena Pirhonen ÅF-Consult shows. The study analyses how the integration of pre-combustion carbon capture technology in the gas-fired combined heat and power (CHP) plant affects the efficiency, power-to-heat ratio, CO2 emissions and costs of the power plant.
To close the nuclear gap in Germany's power generation capacity, "more new gas- and coal-fired power plants need to be built than we had estimated," Rainer Brüderle, head of the German liberal party FDP, said over the weekend. "And this may well cost more than we thought," he told the paper "Welt am Sonntag".
Delaware Municipal Electric Corporation, Inc. (DEMEC) has commissioned Unit#2 - a 100 MW gas-fired peaking facility - at the Beasley Power Station. Construction costs of the unit totalled US$30 million, DEMEC confirmed today.
Mitsubishi Heavy Industries, Ltd. (MHI) is gearing up to develop basic technologies for a triple combined cycle power generation system integrating solid oxide fuel cells (SOFC) and a gas turbine combined cycle (GTCC) power generation system.
China will more than double its natural gas consumption over the next five years, the International Energy Agency (IEA) forecasts in its Medium-Term Gas Market Report 2012, released at the World Gas Conference 2012.
"As gas competes against other energy sources in all market segments, notably in the power sector, pricing conditions are a key element to keep it competitive everywhere," IEA Executive Director, Maria van der Hoeven, said at the official presentation of the report on Thursday.
Haldia Petrochemicals in India has plans to retrofit one of its gas turbines with "uprated" parts this year. "This will reduce the heat rate and increase the efficiency as well as enhance the life of the components," Nirmallya Sen, Deputy General Manager (Mechanical) at the plant, told Gas to Power Journal in an interview. Turbine capacity will also be enhanced by three to four megawatts, he added.
Germany's gas consumption could rise markedly in the medium term as a result of the nuclear phase out – it could impact prices across Europe, say analysts. Much depends, however, on whether Chancellor Merkel's energy policy – alias 'Energiewende' – will ultimately work out.
In an effort to alleviate Tanzania's power shortage, Japan's Sumitomo Corp. and the Tanzania's state-controlled Electric Supply Co. have joined forces to build a 240MW gas-fired power plant at Kinyerezi in the Dar es Salaam Region of Tanzania.
Uncertainty surrounding China's future energy mix is alerting key global gas suppliers such as Qatar's Rasgas. "The Chinese power market is perhaps the biggest demand uncertainty in Asia. Coal has been the fuel of choice so far, but as environmental concerns increase, gas has a vast opportunity to have an increased role in the market," Al Mohannadi, general manager of the Qatari LNG producer Rasgas he told delegates at the World Gas Conference (WGC2012) in Kuala Lumpur on Wednesday.
E.ON, Germany's largest utility, is facing a loss in the lower double-digit million euro range on deals of an ex-trader. E.ON did not disclose whether the losses were incurred by traded contracts of natural gas or electricity in the forward market.
Vattenfall Europe has applied to local authorities for planning permission build a new gas-fired power plant in the city of Wedel near Hamburg. The plant is scheduled to start operations by the end of 2016 and will to replace an existing coal plant built in the 1960s, the Sweden-based utility said.
Investments in carbon capture storage (CCS) for new-built and operational power plants has a softening effect the carbon price - albeit not a big one, Energy Brainpool's chief analyst Tobias Federico said. Gas-fired power plants are allowed to operate without CCS until 2045 in the U.K., the Department of Energy and Climate Change (DECC) confirmed.
To launch capacity payment schemes at a national level in EU countries makes "no sense", said Philip Lowe, Director General for DG Energy in the European Commission. Only pan-European mechanisms could make sense and would support investment in new gas-fired plants, he said at Eurelectric's annual conference in Malta on Tuesday.
As renewable, intermittent wind and solar energy replaces traditional base load coal-fired and nuclear energy in Europe, the need for substantial sources of cost-effective backup power will be great, forecasts Eleazar Rodriguez, Director of Sales for Spain, Portugal and Latin America at Pratt & Whitney Power Systems.
