GE’s Jenbacher Cogeneration Technology Set to Power Urban District Energy Project in Melbourne

 

• 2-Megawatt (MW) Jenbacher Unit to Help Cogent Energy Supply Power, Heat and Cooling for Dandenong Commercial District
• Cogeneration Plant Could be Expanded Up to 6 MW to Meet Melbourne’s Growing Energy Needs

MELBOURNE, AUSTRALIA—March 26, 2012—One of GE’s (NYSE: GE) natural gas-fired Jenbacher gas engines will be powering a cogeneration plant that will provide reliable electricity and thermal energy for a major urban revitalization initiative in Dandenong, Victoria. Built by Cogent Energy, the plant will play a pivotal role in the VicUrban-lead Revitalising Central Dandenong (RCD) initiative that is rejuvenating the south-east region of Melbourne.

The collaboration marks GE’s first urban district energy project in Australia.Clarke Energy Australia, GE’s authorized distributor for Jenbacher gas engines in Australia, will supply project owner Cogent Energy with a 2-MW,J612 Jenbacher cogeneration unit for Phase 1 of the new power facility, which could be expanded to 6 MW.

GE’s ecomagination-qualified Jenbacher system was shipped to the Dandenong site in January, with commercial operation set to begin this year. The gas engine is expected to save the equivalent of about 9,900 tons of carbon emissions a year, which equals the removal of more than 5,500 cars from the road.

The cogeneration plant is set to dramatically reduce the emissions and energy use of the Dandedong Commercial District by reducing its reliance on energy from the grid. The plant also will have the capacity to produce surplus hot water, which Cogent Energy will then sell back to local commercial buildings to provide cooling via building owner-supplied absorption chillers.

“Helping central Dandenong transform itself into a vibrant, 21^st century retail and services district will require a reliable, cleaner, cost-effective supply of energy to meet the growing needs of the area’s business and residential communities,” said Blair Healy, manager of Cogent Energy. “GE’s Jenbacher technology offers the optimal energy efficiency we required to make this project successful.”

“Australia represents an important growth region for GE as more customers embrace various distributed power applications—including industrial cogeneration—to bring the sources of energy production closer to end-users,” said Rafael Santana, CEO and president—Gas Engines for GE Energy.

GE is helping customers worldwide to generate reliable on-site electricity and heat at or near the point of use through its comprehensive suite of distributed power solutions ranging in size from 119 kilowatts to 100 MW. The fuel flexibility of GE’s Jenbacher gas engines and its other distributed energy technologies also promotes greater regional energy and economic security by enabling countries to use more of their own energy resources to meet their domestic needs.

The Dandenong project builds on GE’s commitment to supporting Australia’s energy goals. The company’s involvement in Australia dates back to 1902 when GE installed one of the electric motors in Sydney to open the Pyrmont Bridge over Darling Harbour.

More recently, in September 2011, GE announced it would supply an integrated solution of on-site power and water filtration equipment to a consortium that is building a water treatment plant on behalf of Australian coal seam gas company QGC. The project, located at QGC’s Kenya site near Chinchilla in Queensland, integrates GE’s Jenbacher and Waukesha gas engines for the first time. The units will generate on-site power for GE’s advanced membrane and thermal water treatment technologies that will desalinate water produced during the extraction of coal seam gas.

GE’s Jenbacher gas engines are designed to run soley on a variety of gases, which results in high levels of generator efficiency, reliability and environmental performance.

Many of GE’s Jenbacher products are ecomagination-qualified, providing customers with products that improve their operating performance and reduce environmental impact. Ecomagination is GE’s business strategy to help meet customers’ demand for products that improve their bottom line and reduce their impact on the environment. Ecomagination reflects GE’s commitment to invest in a future that creates innovative solutions to environmental challenges.

n Wilmington, North Carolina, local institutions are leading the way in building efficiency and sustainability. From the WAVE Transit Forden Station to the Wilmington Convention Center to the city’s street sweeper complex, Wilmington is saving money by saving energy and supporting job growth in energy efficiency technologies. 
 


Last week, I experienced first-hand how Wilmington public buildings are leveraging energy efficiency and clean energy technologies to save money and reduce energy waste. I joined Representative Mike McIntyre, Mayor Bill Saffo and Joy Allen, executive director of the Cape Fear Green Building Alliance, on a tour of the city’s energy efficient buildings. 
 


At the Forden Station -- the first LEED Gold registered public building to break ground in the state of North Carolina -- on-site geothermal heating and cooling systems have helped reduce energy consumption by 45 percent. Snipes Academy of Arts and Design utilizes a water source heat pump system and outside air system for the school’s heating and cooling. Through interactive real-time energy data tools, Snipes students incorporate energy use data in their classroom projects and studies. 
 


Reducing energy waste in buildings is an important element for a sustainable energy future. In the United States, buildings consume about 40 percent of all U.S. energy, contributing a significant amount to overall energy costs. In Wilmington, the Cape Fear Green Building Alliance is helping train local energy auditors and building analysts to conduct energy efficiency upgrades and capture the savings. 
 


Nationally, through the Better Buildings Challenge, more than 60 companies, cities, universities, hospitals and other partners have committed to upgrading more than 1.6 billion square feet of building space across the country -- which will jobs, eliminate waste and help make our commercial and industrial buildings 20 percent more efficient by 2020.

Oh, the (Energy-Related) Stories I Have Heard...

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


I don't have an interesting tidbit, video, or page to link to today, so I thought I would share a few things I've heard people say about saving energy. I'd call them "stories," except I'm paraphrasing and summarizing so much that it's more like random advice that I've heard people give. I think they're kind of fun reminders that, well, we are all pretty energy-savvy here, but there's still a lot of education that needs to be done.
Let's get this started!

Once upon a time, I knew someone who was sure that it would cost less to use a gas fireplace to heat their living room than it would to let the central heating run. They figured the fireplace could heat a small area better than the central air, which would have to heat the whole house.

Is that true? It depends! You need to check your utilities to know that, because they charge you differently for gas than for electricity. But to do that, you need to know how much gas your fireplace actually uses. (And that's useful information. I wonder if my apartment could tell me that much about my fireplace?) For me, though? Gas is kind of pricy. If I had a wood and pellet-burning fireplace I could at least look that up on Energy Savers.

I once knew someone who thought they could turn the heat off and use a space heater instead. This would only be the case if you had a space heater that used less energy while it was on than your central heating did. So! Look into how much energy your space heater uses. Learn about your space heater. I can assure you that every single one of the cheap-o brands I've bought were so grossly inefficient that they couldn't be used as my primary heating source.

...Of course, there's another reason to not try to heat your entire house with a space heater. And that's because most of you live in a place where it will freeze, and you can't decide to just turn your heat off to save money.

Because, you see, I also knew someone who thought it was fine to just turn the heat off all winter and rely on blankets and sweaters instead. Think of your pipes before you do that!

And, finally, here's a weird one. I knew someone who had heard the truism that running the oven heats up your kitchen. That's true! This person decided that, consequentially, this meant that running the oven with nothing in it was a good way to heat a kitchen. And... yeah, don't do that. If you want to heat your house, do it with something that's designed for heating. If you try to be creative about it you might burn down your house.

I think the lesson is this: If you're serious about saving energy, you have to do a little research. Yes, yes, "research" is a word that makes some people cringe. Sorry. But you have to know how much energy you use to know how to cut back in the right places.

Figure out where you're wasting energy. Read your utility bill. Know how much you have to pay for electricity or gas. Know how much it costs to run your appliances. (If you want to do the math, you can estimate your energy use with this handy formula) Then you can decide what you should heat your home with and for how long.

Energy Dept. & Volvo Build More Efficient Trucks & Mfg. Plants

News release from the U.S. Department of Energy:

Energy Department, Volvo Partnership Builds More Efficient Trucks and Manufacturing Plants

January 27, 2012 

Washington, D.C. –Today, Acting Under Secretary of Energy Arun Majumdar joined with North Carolina Congressman Howard Coble (NC-6) to tour the Volvo Group’s truck headquarters in Greensboro, North Carolina, and highlight the blueprint for an America built to last laid out by President Obama in his State of the Union address earlier this week. The Department of Energy is partnering with companies like the Volvo Group to help harness American ingenuity to commercialize and deploy cutting-edge trucking technologies that will help boost the competitiveness of the U.S. auto and manufacturing industry, reduce our dependence on foreign oil, and create jobs for American workers.

“Earlier this week in his State of the Union address, President Obama outlined a blueprint for a stronger American economy based on a resurgence in American manufacturing and innovations in the way we use energy,” said Dr. Majumdar. “Companies like the Volvo Group that are pursuing energy efficiency in their operations, putting Americans to work, and building more fuel-efficient vehicles underscore how investments in clean energy technology are helping to secure America’s future economic prosperity.”

In partnership with the Energy Department, the Volvo Group is helping to lead the industry to advance innovative clean energy vehicle technologies and energy-efficient manufacturing. Through the Department’s SuperTruck program, the Volvo Group was awarded $19 million – which the company is matching dollar for dollar – to improve the efficiency of heavy-duty vehicles like the Mack and Volvo Trucks. Volvo Group has also embraced manufacturing efficiency as part of the DOE’s Better Buildings, Better Plants Program, pledging to reduce the energy intensity of its manufacturing plants with assistance and guidance from the Energy Department. These steps to become more energy-efficient will reduce operating costs at the facility, improving the competitiveness of the company’s products and manufacturing plants.

Dr. Majumdar and Congressman Coble were hosted by Dennis Slagle, Executive Vice President of Volvo Group Trucks Sales & Marketing - Americas, on the tour of the Volvo Group’s Technical Center, which is in the midst of an $8 million expansion.

The Volvo Group’s award was one of four Energy Department-sponsored SuperTruck development projects, which focus on increasing the fuel efficiency of Class 8 trucks – better known as 18-wheelers – by 50 percent.  To achieve this goal, companies like the Volvo Group are developing and improving vehicle technologies in engine efficiency, aerodynamics, waste heat recovery,  and hybridization, among other approaches.  Through the SuperTruck program, the Energy Department expects fuel economy increases from 6.5 miles per gallon to 9.75 miles per gallon – saving long-haul truckers more than $15,000 per truck per year in fuel costs.

Class 8 trucks represent only 4 percent of the on-road vehicles in America, but are responsible for almost 20 percent of the country’s on-road fuel consumption.  Implementation of SuperTruck technologies will not only lessen the nation’s dependence on petroleum, but also improve the global competitiveness of U.S. truck manufacturers.

While Volvo is building more efficient vehicles, the company is also improving the energy efficiency of the manufacturing plants that make them. In December 2009, the company joined the Department of Energy’s Save Energy Now LEADER initiative, now known as the Better Buildings, Better Plants Program, to begin an ambitious effort to significantly reduce the energy intensity of its operations as a way to increase competitiveness. Since then, Volvo’s New River Valley plant, located in Dublin, Virginia, has implemented a range of measures with guidance from the Department’s technical experts that reduced its energy intensity by almost 30 percent in just one year. Embracing energy efficiency measures helped Volvo cut costs and keep operations—and jobs—for its truck manufacturing business here in the United States.

Volvo Truck Corporation is one of the leading heavy truck and engine manufacturers in the world. Volvo Trucks manufactures a line of Class 8 trucks, and is known as a major innovator in the heavy-vehicle industry, selling products in more than 180 markets worldwide.

Winter Weather No Match for Biodiesel Blends

From the National Biodiesel Board:

New York City Plows the Way with Biodiesel Blends

The largest municipal user of biodiesel, New York City, even counts on biodiesel blends to power snow removal equipment. The New York City Parks & Recreation Department was the first city agency to pilot biodiesel in 2005 and continues its use of B20.

The 850-vehicle strong diesel fleet helps to maintain more than 29,000 acres in New York City. The fleet includes more than 40 different types of vehicles and equipment – handling everything from snow removal to landscape and parks maintenance to road construction and waste management.

The New York City Sanitation Department also uses biodiesel blends in vehicles used to fight winter weather, such as salt spreaders and plows. "We can't afford for our garbage trucks not to run," said Supervisor of Mechanics Spiro Kattan. "Our trucks don't only pick up garbage, they are also equipped with snowplow hitches. We're a part of the city's snow emergency plans and the residents of New York City would not be too happy if our vehicles went down during a snow storm."

Further, JFK International Airport uses B20 to keep runways clear even in the worst of snowstorms.

Bioheat ® Warms Homes & Offices

In addition, New York City enacted a groundbreaking law requiring that all heating oil sold in the city contain at least 2 percent biodiesel beginning in October 2012. Bioheat® is already keeping many homes and offices warm this winter, including New York City Parks buildings.

NBB’s website includes a number of resources about the operability of biodiesel blends in cold climates -- www.biodiesel.org/cold. For more information on Bioheat®, visit: http://www.bioheatonline.com.

DOE Blog Post: Farming Out Heat & Electricity thru Biopower

Farming Out Heat and Electricity through Biopower

December 16, 2011

 

Cows like these in Skagit County, Washington, supply the biodigester developed by Kevin Maas of Farm Power up to 70,000 gallons of manure per day. The newest Farm Power facility in Washington generates enough electricity to power 500 homes. Photo courtesy of sea_turtle.

Communications Liaison, State Energy Program

Maas' biodigester:

• Creates electricity from the biogas produced through anaerobic digestion.
• Recycles dried, fibrous solids from the process to make cow bedding.
• Returns digested liquid waste back to farms for fertilizer.

Five years ago, Kevin Maas and his brother Daryl started a business producing electricity from what many would consider an unlikely source -- cow manure.

Kevin Maas developed an anaerobic digester and then a company around a biodigester, which heats and processes dairy manure and other organic wastes in an oxygen-free environment designed to induce digestion by bacteria and then collects the bacteria’s output -- methane-rich biogas.

The system, the first-of-its-kind in the state, stores the gas from the biodigester and then feeds it through bright yellow pipes into an engine generator to produce electricity. After digestion, the fibrous solids are separated and dried, then returned to dairy farms for use as cow bedding. The digested liquid is also returned to farms, stored in lagoons, and then spread on fields, providing nutrients for crop production.

A few years later after learning about the State Energy Program, the Maas brothers applied for and received a $1.06 million Recovery Act grant from the Department of Commerce to construct a second digester near Lynden, a small Washington town just south of the Canadian border.

Nearby MJD Farms, a dairy farm with over 2,000 cows, agreed to supply the manure -- 70,000 gallons per day. 

A closed-loop heat extractor at the Lynden facility uses the heat produced by the burning methane biogas for multiple purposes. First, it heats the digester vessel to sustain bacteria growth. Second, it dries the fiber product. Third, it heats water that is piped to a nearby commercial greenhouse for radiant floor heating.

Maas calculates that the greenhouse, owned by Van Wingerden Greenhouses, will save approximately $30,000 per year in energy costs due to its participation in the digester project. The greenhouse employs 15 workers.

Farm Power Lynden generates over 6,000 megawatt hours of electricity per year, 20 times the amount of power to run its own operations, or enough electricity to power 500 homes. The excess electricity is sold to Puget Sound Energy under a 10-year fixed-price contract.

The methane emissions eliminated by the Lynden facility are projected to reduce net annual greenhouse gas emissions equivalent to taking 3,000 cars off the road.

Farm Power is currently working to establish additional digester projects in the state. “The State Energy Program is outstanding,” said Maas. 

Anaerobic digestion of agricultural waste is a proven and rapidly growing source of renewable energy generated at more than 150 other facilities around the country.
