MAN Diesel & Turbo has launched the 35/44G engine as its latest addition to its four-stroke power portfolio. With an electrical efficiency of 47.2 percent, the newly developed Otto gas engine is available for Combined Heat & Power (CHP) or can be installed in a combined cycle mode jointly with an MAN steam turbine of the MARC series.

Alstom Grid has delivered and installed a new Distribution Management System (DMS) to Nashville Electric Service (NES) that is designed to help reduce peak demand for electricity up to 40 MW by reducing voltage and enhancing awareness for energy efficiency, safety and reliability.

Shell targets a growing engine oils segment with its new sour-gas compatible lubricating oil. "There could be a 10% sales growth in the stationary gas engine oils segment this year," Richard Holdsworth, Global Brand Manager for Shell Power Lubricants told Gas to Power Journal.

Green Field Energy Services, Inc. has signed a global supplier agreement with GE Oil & Gas to deliver low-cost, gas burning power generation solutions to enhance oil and gas upstream operations and hydraulic fracturing.

Development of Pratt & Whitney Power Systems (PWPS) new 60 megawatt (MW) class models is likely to be accelerated under the new ownership by Mitsubishi Heavy Industries (MHI), industry sources told Gas to Power Journal. PWPS' new 60 MW model will complement the proven 30 MW machines.

Power plant operators of flexible capacity can cash in on differentials between real-time electricity prices and day-ahead prices, triggered by the rising penetration of intermittent renewable energy sources, says Thomas Graves, senior development manager at Burns & McDonnell Engineering.

Improved combustion technology at Alstom's GT 26 gas turbine can cope with an expanding range of fuel compositions while maintaining emissions and reliability, says Alexander Bill, Service Manager at Alstom's Power Division.

Doors are opening to POWER-GEN International at the Orange County Convention Centre in Orlando, Florida, today. More than 20,000 attendees are expected to visit the exhibition and attend conference sessions.

The U.S. Department of Energy's Advanced Research Projects Agency (ARPA-E) will grant Pratt & Whitney Rocketdyne funding worth $5 million for three cost-sharing projects set to improve efficiency and reduce costs of gas turbines in commercial-scale power plants.

The resemblance between Montana, a state in north-western United States and European countries like Spain, Denmark or Germany is striking. 
"What we are seeing in Montana and also here in Europe is that our FT8 SWIFTPAC aeroderivative gas turbines are being used to maintain adequate power flows in the grid to counterbalance fluctuating wind energy," says Swift Tarbell, Pratt & Whitney Power Systems Area Director for Europe.

Two of GE's Jenbacher gas engines have been installed to power the first LNG-fuelled drilling rigs in the Marcellus Shale region of Pennsylvania. Seneca Ressources Corp. converted the power plants of two existing diesel-powered rigs to use cleaner-burning LNG in GE's 1-megawatt Jenbacher J320 turbocharged natural gas engines.

The GT26 and GT24 gas turbines offer greater flexibility to suit today's dynamic power markets like the UK. Improved fuel flexibility, flexible operation modes, and unique low load operation capability are achieved through sequential combustion, says Alexander Bill, service manager at Alstom's Power Division.

Deployment of carbon capture storage (CCS) technology will allow for more coal and gas to be used than without CCS, Sean McCoy, analyst at the International Energy Agency (IEA) told Gas to Power Journal.

"More than two thirds of today's fossil fuel reserves would have to remain un-burnt and in the ground in the absence of CCS," he said referring to the IEA's World Energy Outlook 2012.

Norwegian oil and gas major Statoil has selected Siemens' PostCap process for phase-3 in the technology qualification program for the carbon capture and storage (CCS) plant at the combined-heat and power plant at the refinery in Mongstad. The final phase of the qualification process will come to an end in April 2013.

With abundant availability of natural gas from conventional and shale resources in the US, there is no economic incentive to develop gas hydrate resources, as a further source of gas supply for power plants and industrial use, says the US Department of Energy (EIA).
