Industry Milestone: GE’s Heavy Duty Gas Turbines Surpass 2 Million Fired Hours on Low Carbon-Intensity Fuels

28 March 2012
Industry Milestone: GE’s Heavy Duty Gas Turbines Surpass 2 Million Fired Hours on Low Carbon-Intensity Fuels
 

  • Waste Fuels from Industrial Operations Like Steelmaking Produce Power with Zero Incremental CO2 Emissions
  • Power from Coal Gasification Enables Future Generations of Low Carbon Coal-Fired Plants
  • GE Low-Carbon Technologies Demonstrate Maturity, Reliability and Affordability

ATLANTA, GA.—March 28, 2012—GE’s (NYSE: GE) fleet of 47 heavy duty gas turbines operating on low British thermal unit (BTU) fuels has accumulated more than 2 million fired hours, an operational milestone that underscores GE’s commitment to developing specialized solutions that meet the demands of today’s evolving energy industry.

Low BTU, or low calorific value fuels have significantly less heating values than natural gas. Examples include syngas, steel mill gases and dilute natural gas. These fuels are lighter than natural gas and have less energy per unit volume.

The fuel flexibility inherent in GE’s B, E and F-class turbines has allowed these units to operate on low BTU fuels in a variety of applications, including integrated gasification combined-cycle (IGCC), refinery-based IGCC and steel mills.

“In a carbon-constrained environment, the technology trend is for combustion systems capable of burning syngas and other nontraditional fuels while also delivering the required operability. In this context, the strong operational experience gained by GE gas turbines with a wide variety of fuels creates favorable prospects, both for robust E-class machines and for F-class machines that deliver high performance,” said Paul Browning, president and CEO—Thermal Products for GE Energy.

To achieve the same heat input as natural gas-fired units, low BTU fuels need increased fuel flow. This flow rate requires the fleet to use GE’s Multi Nozzle Quiet Combustion (MNQC) and standard (single nozzle) syngas combustors, which provide robust and reliable operation on low BTU fuels.

The hours accumulated by the fleet include projects totaling more than 4 gigawatts of installed power generation capacity at 21 plants. One million of those hours have been achieved on GE’s E-class turbines. Roughly 600,000 hours have been accumulated on GE’s B-class while the remaining 400,000 hours were amassed on the F-class. Some of the turbines have been running on syngas or other fuels for more than a decade including a large coal-based IGCC facility in Florida and an Italian refinery. Others are newer installations operating at locations in the United States, Germany, Italy, Canada, Netherlands, Czech Republic, China, Middle East,and Singapore.

A case in point is the Wuhan Iron & Steel Group Corp. (WISCO) steel mill near Wuhan City in Hubei Province, China. To comply with China’s goals to reduce energy consumption and emissions, WISCO installed a combined-cycle power plant—powered by two GE 9E Gas Turbines—at the Wuhan mill.

Reusing the mill’s own “blast furnace” and “coke oven” waste gases (BFG and COG) as “free” fuel, the two GE 109 combined-cycle systems each generate 164 megawatts of onsite power to support the mill’s activities. Currently, the power plant’s annual output is 1 billion kWh/a, with a guaranteed electrical efficiency greater than 42 percent (LHV).

The key benefits of this project for WISCO include a reduction in emissions associated with the waste gases created during the steel production process and new revenues generated by the sale of some of the power plant’s electricity to the local grid.

GE’s fleet of heavy duty gas turbines operating on low BTU fuels continues to grow, as customers look to do more with less.

News Release from GE - Landfill Gas

23 February 2012
GE Gas Engine Technology to Power China’s Largest Landfill Gas Project
 

  • GE’s Jenbacher Gas Engines to Reduce Carbon Dioxide Emissions by More than 340,000 Tons per Year and Greenhouse Gas by Nearly 19 Million Cubic Meters Each Year
  • Project Supports Chinese Government’s 12th Five-Year Plan to Invest More than RMB260 Billion in the Waste Treatment Industry by 2015
  • GE Cements Leadership Position in China with Latest Alternative Power-to-Energy Project

SHANGHAI, CHINA—February 23, 2012
GE (NYSE: GE) today announced that its ecomagination-qualified Jenbacher gas engines will power China’s largest landfill gas (LFG) power generation project. The Laogang LFG project is owned by Laogang Renewable Energy Co., a joint venture formed by Veolia and Shanghai Environment Group, and supports the Chinese government’s 12th Five-Year Plan, during which China plans to invest more than RMB$260 billion in the waste treatment industry including waste-to-energy initiatives by 2015[1].
“Traditionally, landfill methane as a potent greenhouse gas has been released directly into the air,” said Chen Hongzhang, general manager, Laogang Renewable Energy Co. “By using GE’s gas engines fueled by LFG, we expect to save emissions by over 340,000 tons of carbon dioxide equivalent per year, significantly improving the local environment in Shanghai.”
Seven of GE’s ecomagination-qualified Jenbacher J420 gas engines, which will provide about 10 megawatts of electricity, will power the new Laogang LFG facility located in Shanghai. Each J420 engine combusts 2.7 million cubic meters (m3) of methane each year, providing an overall yearly reduction of greenhouse gas of around 18.9 million m³ for the seven gas engines. The Renewable Energy Company will sell any excess electricity generated to the grid. This project is an example of how GE’s portfolio of innovative distributed power solutions, ranging from 100 kilowatts (kW) to 100 megawatts (MW), gives businesses and communities around the world the ability to generate reliable and efficient power anywhere, whether on or off the grid.
GE’s Jenbacher landfill gas engines use the gas—consisting of methane, carbon dioxide (CO2) and nitrogen—created during the decomposition of organic substances in a landfill. Methane has a global warming factor 21 times greater than carbon dioxide, the most widely recognized greenhouse gas affecting climate change. With a calorific value of approximately 5 kWh/Nm³, landfill gas constitutes a high-value fuel for gas engines that can be effectively used for energy generation. One of GE’s Jenbacher J420 gas engines running on landfill gas can generate 1.4 MW electricity while saving the emissions of more than 49,000 metric tons of CO2-equivalent per year through methane destruction and displaced grid electricity production; this is equivalent to the annual CO2 emissions of more than 9,500 passenger cars on U.S. roads.
“This important project underscores our commitment to providing alternative energy solutions to help China meet its energy goals and cements our position as a leader in this segment,” said Rafael Santana, president and CEO—Gas Engines for GE Energy. “Our Jenbacher gas engines combine high efficiency and reliability with fuel flexibility to meet our customers’ needs with positive environmental impact. The seven Jenbacher J420 gas engines running on landfill gas are designed to generate almost 80 megawatt hours of electricity per year, which could power more than 46,000 Chinese households per year[2].”
The gas engines are scheduled to begin shipping in the second quarter of 2012 with commercial operation expected in December 2012.
This project is the latest in GE’s landfill gas solutions using Jenbacher gas engines. On October 31, 2011, GE announced that it had supplied a fourth J420 Jenbacher gas engine to Asja Brasil’s new 4.3-megawatt Belo Horizonte landfill-gas-to-energy (LFGTE) project in Brazil, helping to meet the country’s goals to increase the production of renewable and alternative energy.
On October 11, 2011, GE announced that it joined government officials and utility representatives at the Golden Triangle Regional Landfill in northeastern Mississippi in the United States to mark the commercial start up of the state’s first LFGTE project that will support the regional grid. Owned by the Golden Triangle Regional Solid Waste Management Authority (GTRSWMA), the LFGTE facility uses an ecomagination-qualified, GE J320 Jenbacher landfill gas engine to generate nearly 1 MW of renewable power sold through Tennessee Valley Authority’s renewable power initiative—enough to support about 700 average U.S. homes.
GE’s alternative gas-to-power portfolio includes its Jenbacher andWaukesha gas engines, which are specifically designed to provide the fuel flexibility needed to accommodate the use of alternative fuels such as landfill gas while offering high levels of electrical efficiency. GE’s Jenbacher landfill gas engines are part of the ecomagination portfolio for successfully demonstrating that converting landfill gas to electricity demonstrates both improved value and environmental performance. Ecomagination is GE’s commitment to invest in a future that creates innovative solutions to global environmental challenges.

Electrofuels

From the blog of the U.S. Dept. of Energy:


Electrofuels: Tiny Organisms Making a Big Impact

February 16, 2012


Electrofuels: Tiny Organisms Making a Big Impact

They say a picture is worth a thousand words — but what happens when what you want to look at is impossible to see?

That’s where the Advanced Research Projects Agency-Energy’s Electrofuels program comes in. The 13 projects that make up the program seek to develop renewable liquid fuels that use microorganisms to harness chemical or electrical energy to convert carbon dioxide into liquid fuels, without using petroleum or biomass. For example, scientists at Columbia University are using bacteria to optimize the conversion of carbon dioxide and ammonia into a liquid transportation fuel similar to gasoline.

If successful, the projects supported by ARPA-E could change the game – breaking our dependence on imported oil and powering our vehicles with homegrown fuels.

Check out the infographic above to see how tiny organisms are making a big impact, or see electrofuels projects in action at ARPA-E’s 2012 Energy Innovation Summit, held February 27-29 right outside Washington, D.C. For more information, visit http://energyinnovationsummit.com/

The Rise of Landfill Gas to Energy

The following is an excerpt of an article with the above title in the January 2012 issue of Waste Age magazine:


Landfill gas (LFG) provides power for one million homes and heat for 737,000 homes across the country.  It provides 14 billion kilowatt-hours of electricity and 102 billion cu. ft of LFG for direct use by industry.  It contributes to the nation’s supply of natural gas and clean-burning fuel for vehicles.

The environmental benefits of these LFG uses are huge.  According to the U.S. Environmental Protection Agency (EPA), the use of LFG reduced the consumption of oil in the United States by about 229 million barrels of oil last year.

Using LFG also reduces greenhouse gas emissions.  EPA says that landfills rank as the third-largest human-generated source of methane emissions in the United States.  Among greenhouse gases, methane, the fuel component of LFG, is one of the most potent.  For instance, it is 21 times stronger than carbon dioxide.

The EPA also estimates that a typical LFG energy project collects and uses 60 to 90 percent of the methane emitted by a landfill.

Thanks to the environmental benefits of putting LFG to use, landfill-gas-to-energy has begun to emerge as a renewable energy industry.

Consider the landfill-gas-to-energy (LFGTE) project at the Newton County Landfill in Brook, Ind., for example.  There, LFG is helping to manufacture egg cartons.

One of the largest landfills in the country, Newton County, owned by Phoenix-based Republic Services, Inc., receives nearly 2.7 million tons of trash per year.  Recently, the landfill began sending LFG to the neighboring Newton County Renewable Energy Park through a 2,500-foot pipeline.

At the industrial park, Canadian firm Urban Forestf Recyclers Inc. (UFR) of Swift Current, Sask., manufactures packaging, such as egg cartons, from recycled fiber.  The process blends mixed newsprint and cardboard into a slurry that is poured into molds.  The LFG fuels the system of blowers used to dry the molds.

Airlines Emissions System May Be Adjusted in Europe

Airline Emissions System May Be Adjusted in Europe 

By JAMES KANTER

BRUSSELS — The European Union could suspend parts of a new law requiring airlines to account for their greenhouse gas emissions if countries were to make clear progress this year toward establishing a global emissions control system, a senior official said Tuesday.

The comments, by Jos Delbeke, the director general for climate action at the European Commission, came the day after China announced that its carriers would be forbidden to pay any charges under the European emissions system without Beijing’s permission.

The comments were the clearest sign yet that Europeans were considering how to defuse a mounting conflict over the new emissions law with its most important trading partners.

The law, which went into effect Jan. 1, requires airlines to account for all emissions on flights using European airports. Its goal is to speed up the adoption of greener technologies at a time when air traffic, which represents about 3 percent of global carbon dioxide emissions, is growing much faster than gains in efficiency.

But Europe’s bold climate initiative also could push nations heavily reliant on air travel into a trade war because of the effect of the new law on flights outside of European airspace.

Mr. Delbeke said at a conference in Brussels that he could recommend “a conditional suspension” of parts of the system, in which polluters can buy and sell a limited quantity of permits, each representing a ton of carbon dioxide, by the end of the year if nations sped up adoption of an effective global system.

For that to happen, any global system would have (to) be better for climate protection than simply applying the European system that is already in force, Mr. Delbeke said. A global system also would have to treat all airlines similarly and to set emissions reduction targets for a near-term date like 2020 rather than midcentury.

China Balking at EU Airline Emissions Charges

Excerpt from an article in The New York Times

E.U. Rebuffs China's Challenge to Airline Emission System

By JAMES KANTER

BRUSSELS — The European Commission said Monday that it would continue charging airlines for their greenhouse gas emissions, despite an announcement from China that its carriers would be forbidden to pay without its permission.

The E.U. program, which began Jan. 1, requires airlines to account for all emissions on flights using European airports and represents the Union’s boldest move to protect the environment.

“We’re not backing down in our legislation,” said Isaac Valero-Ladrón, a spokesman for the commission, the executive body of the European Union. “We’ll apply this to companies operating in Europe.”

Europe says its system is less costly than portrayed and would speed up the adoption of greener technologies at a time when air traffic, which represents about 3 percent of global carbon dioxide emissions, is growing much faster than gains in efficiency.

Earlier Monday, the Chinese air regulator effectively prohibited the country’s carriers from paying those charges or other fees, or increasing ticket prices in response to the E.U. system, without permission from the government.

The Chinese government said it was also considering unspecified measures to protect Chinese companies, something Europe can ill afford as it looks to China to help ease its debt crisis. European countries also want access to China’s fast-growing economy, including free-spending Chinese tourists who might not show up.

The intensifying dispute is another sign that European environmental regulations could lead to a trade war if governments start retaliating against carriers or products.

GM to Build New CNG Vans for AT&T

News release from AT&T.  Once again, while natural gas is not really renewable energy, its use may be of interest to readers because of its lower carbon footprint, as compared to gasoline or diesel.


GM Wentzville Plant to Build New CNG Vans for AT&T

Order shows AT&T's "continued commitment to alternative fuels and to investing right here in Missouri," says AT&T Missouri President John Sondag

St. Louis, Missouri, February 01, 2012


Fresh on the heels of the announcement that is has deployed its 5,000th alternative fuel vehicle, AT&T* announced today that it plans to take delivery of 1,200 Chevrolet Express dedicated compressed natural gas (CNG) cargo vans to be deployed to AT&T service centers nationwide. It is the largest-ever order of GM CNG vehicles.

“St. Louis is home to AT&T’s Fleet Operations and we have more than 200 alternative fuel vehicles in the state,” said AT&T Missouri President John Sondag.  “This order shows AT&T’s continued commitment to alternative fuels and to investing right here in Missouri.”

AT&T, which has announced its intention to invest up to $565 million to deploy approximately 15,000 alternative fuel vehicles over a 10-year period through 2018, will use the vans to provide and maintain communications, high-speed Internet and television services for AT&T customers. Last week, the company announced the milestone deployment of its 5,000th alternative-fuel vehicle, a Chevrolet Express van, as part of the commitment.

 “CNG technology is important to AT&T because it helps us reduce our fleet-based carbon emissions,” said Jerome Webber, AT&T vice president of Fleet Operations. “It is also cost-effective and readily available in our country right now.” 

According to the U.S Environmental Protection Agency, CNG-powered vans can produce approximately 25 percent fewer carbon dioxide emissions than similar gasoline and diesel-powered vans, which supports AT&T’s corporate commitment to minimize its impact on the environment.

In 2010, AT&T and other large U.S. fleet operators joined in the Department of Energy’s Clean Cities’ National Clean Fleets Partnership as part of a national challenge launched by President Obama to cut America’s petroleum imports by one-third by 2025. Through 2013, AT&T anticipates it will have purchased up to 8,000 CNG vehicles at an estimated cost of $350 million. Additionally, over the life of the commitment, AT&T expects to invest $215 million to replace approximately 7,100 fleet passenger cars with alternative-fuel models.

According to a 2009 Center for Automotive Research report, AT&T’s planned alternative-fuel vehicle initiative would:

  • Save 49 million gallons of gasoline over the 10-year deployment period
  • Reduce carbon emissions by 211,000 metric tons – the greenhouse gas equivalent of removing 38,600 passenger vehicles from the road for one year
More Sustainable Service Garages

Beyond the AFV deployments, AT&T is turning to its service garages to help minimize its environmental footprint and cut operating costs within its overall fleet. These programs include:
  • Redirecting an estimated 60,000 old tires annually through a new recycling program that turns old rubber into fuel and consumer products
  • Recycling all primary garage products, including 180,000 pounds of oil filters; 200,000 gallons of oil; and 23,000 gallons of antifreeze annually
  • Eliminating the purchase of 9,000 pounds of lead annually that were being used to balance new fleet vehicle tires at high speeds

2010 Greenhouse Gas Emissions Data Available

News Release form U.S. EPA:


2010 Greenhouse Gas Emissions Data from Large Facilities Now Available / First release of data through the national GHG reporting program

Release Date: 01/11/2012
Contact Information: Cathy Milbourn (News Media Only), Milbourn.cathy@epa.gov, 202-564-7849, 202-564-4355



WASHINGTON – For the first time, comprehensive greenhouse gas (GHG) data reported directly from large facilities and suppliers across the country are now easily accessible to the public through EPA’s GHG Reporting Program. The 2010 GHG data released today includes public information from facilities in nine industry groups that directly emit large quantities of GHGs, as well as suppliers of certain fossil fuels.

“Thanks to strong collaboration and feedback from industry, states and other organizations, today we have a transparent, powerful data resource available to the public,” said Gina McCarthy, assistant administrator for EPA’s Office of Air and Radiation. “The GHG Reporting Program data provides a critical tool for businesses and other innovators to find cost- and fuel-saving efficiencies that reduce greenhouse gas emissions, and foster technologies to protect public health and the environment.”

EPA’s online data publication tool allows users to view and sort GHG data for calendar year 2010 from over 6,700 facilities in a variety of ways—including by facility, location, industrial sector, and the type of GHG emitted. This information can be used by communities to identify nearby sources of GHGs, help businesses compare and track emissions, and provide information to state and local governments.

GHG data for direct emitters show that in 2010:

•Power plants were the largest stationary sources of direct emissions with 2,324 million metric tons of carbon dioxide equivalent (mmtCO2e), followed by petroleum refineries with emissions of 183 mmtCO2e.

•CO2 accounted for the largest share of direct GHG emissions with 95 percent, followed by methane with 4 percent, and nitrous oxide and fluorinated gases accounting for the remaining 1 percent.

•100 facilities each reported emissions over 7 mmtCO2e, including 96 power plants, two iron and steel mills and two refineries.

Mandated by the FY2008 Consolidated Appropriations Act, EPA launched the GHG Reporting Program in October 2009, requiring the reporting of GHG data from large emission sources across a range of industry sectors, as well as suppliers of products that would emit GHGs if released or combusted. Most reporting entities submitted data for calendar year 2010. However, an additional 12 source categories will begin reporting their 2011 GHG data this year.
