First Time in China: GE’s 9FA Advanced Gas Path Technology to Boost Efficiency at Shanghai Caojing’s Power Station

March 28, 2017

GE’s Advanced Gas Path Technology Will Help Increase Output by Approximately 25 Megawatts, Boost Efficiency and Reduce Emissions at the PlantStation Serves as Model for Utilities in China Seeking to Make Their Plants More Efficient and Reliable

SHANGHAI—March 28, 2017—GE’s Power Services (NYSE: GE) signed a milestone agreement to provide Advanced Gas Path (AGP) upgrades for two GE 9FA gas turbines at the Caojing combined-cycle power station in China, marking the company’s first 9FA AGP upgrade in the country. The deal will help increase the output and efficiency of the 790-megawatt (MW) plant—the largest industrial cogeneration facility in Shanghai. In addition, GE signed a 25-year services agreement with Shanghai Caojing Co-Generation Co., Ltd., the owner of the Caojing power station, extending a previous collaboration between the two companies.

“China’s surging energy demands and continued growth in the petrochemical industry make it essential for us to continually improve the performance and availability of the Caojing combined-cycle plant to support local production requirements,” said Mr. Peigang Shi, general manager of Shanghai Caojing Co-Generation Co., Ltd. “This upgrade project will enable us to boost our supply of power and steam to the Shanghai Chemical Industry Park—one of the leading petrochemical bases in Asia—with higher efficiency and without increasing emissions.”

The gas turbine AGP technology, part of GE’s Fleet360* platform of total plant solutions, is engineered to increase turbine output by more than 6 percent, reduce heat rate by more than 1.5 percent and extend maintenance intervals from 24,000 to 32,000 factored hours—a leading figure in the industry.

Increasing the efficiency of existing thermal power plants has become a top global priority as countries seek to reach their emissions-reduction goals. GE’s recent Ecomagination study found that carbon dioxide (CO₂) emissions from the world’s fleets of natural gas and coal-fired plants can be reduced by 10 percent when existing hardware and software solutions are fully applied. Upgrades to existing plants can be done relatively quickly and cost-effectively. According to the study, the average global efficiency of gas plants can be improved by up to 1.8 percent through hardware improvements such as turbine and boiler upgrades and an additional 1.5 percent through software solutions and data analytics.

“The AGP and software upgrades can be implemented in the upcoming major outage, therefore delivering immediate benefit to Caojing,” said Sunny Xue, commercial general manager for GE’s Power Services in China. “Thanks to advanced material and flow-path design, our AGP technology provides 9FA.03 gas turbines with improved efficiency, longer maintenance intervals and longer parts life, helping to assure our customer’s units remain competitive over time.”

The deal extends a previous services agreement signed by GE and Shanghai Caojing Co-Generation Company in 2013, which saw implementation of the first Dry Low NOx 2.6+ combustion system upgrade for 9FA.03 gas turbines in Asia. That upgrade helped the Caojing plant achieve NOx emissions levels below 15 parts per million, a 40 percent reduction from the previous level.

China’s New “Weather-Controlling Tech” Could Make it Rain on Demand

Third Party Contents

 FuturismMS

IN BRIEF

China has spent $168 million on cloud seeding technology to hopefully manipulate the weather and combat drought and extreme weather due to climate changeCloud seeding technology has existed for a long time, however because of early false claims and deep-rooted skepticism, there isn't sufficient research to back up the tech

CLOUD SEEDING

The China Meteorological Administration wants to increase rainfall and snow across 960,000 square kilometers of the country. A more effective way of making this happen that doesn’t involve a ritualistic rain dance? Spending $168 million on cloud seeding technology that they hope will allow them to manipulate the weather.

Here’s how it works. The money will be invested into four new aircrafts, upgrading eight existing planes, and launching 900 rocket systems that will allow them to sprinkle substances above the clouds that could induce the rainmaking process. These substances range from silver iodide to dry ice. Adding these chemicals into clouds might lower their temperature and speed up the condensation process.

While this method has yet to be scientifically proven, the country claims it has already helped them to increase precipitation by 55 billion cubic meters from 2006 to 2016, especially in the western part of China.

“The […] project is expected to help with “ecological security, water resource allocation, drought fighting and forest fire prevention” in Gansu, Shaanxi, Qinghai, Ningxia, Xinjiang and Inner Mongolia, all of which are western regions plagued by water shortages.” reports The South China Morning Post.

MAKE IT RAIN

Cloud seeding schemes have been around for years. And theoretically, the method makes scientific sense. However, unrealistic claims regarding its success when it was first introduced prompted experiments with cloud seeding to be regarded with apprehension. Through the years, the consensus among weather scientists was that cloud seeding’s positive results had to be supported with greater scientific data. Ultimately, even with advanced tools and techniques, it’s still very difficult to establish whether weather conditions were prompted artificially or naturally-occurring.

However, this lack of concrete evidence hasn’t stopped people from using this weather modification technique. China, for instance, has used the method to ensure weather conditions for major events like the Beijing Olympics. Back in 2008, China launched over a thousand rockets to release silver iodide over the city sky to clear storm clouds and ensure that the international event would remain rain-free.

To that end, they’re now hoping that the same technique will work to address changes in temperature and precipitation caused by climate change, especially in drought-stricken regions, cities where they need to increase rainfall, or in cities suffering from heavy smog where they need rain to clear the air.

There is still a lot of uncertainty surrounding cloud seeding, and scientists are still trying to find concrete solutions in the technique. But continued research into the field will indeed prove to be invaluable during a time where countries continue to experience extreme weather events due to climate change.

Jordan Gaines Lewis, Neuroscience Doctoral Candidate, Pennsylvania State University

Thursday 16 March 2017

Anyone who knows me also knows that I have a huge sweet tooth. I always have. My friend and fellow graduate student Andrew is equally afflicted, and living in Hershey, Pennsylvania – the “Chocolate Capital of the World” – doesn’t help either of us.

But Andrew is braver than I am. Last year, he gave up sweets for Lent. I can’t say that I’m following in his footsteps this year, but if you are abstaining from sweets for Lent this year, here’s what you can expect over the next 40 days.

Sugar: natural reward, unnatural fix

In neuroscience, food is something we call a “natural reward.” In order for us to survive as a species, things like eating, having sex and nurturing others must be pleasurable to the brain so that these behaviours are reinforced and repeated.

Evolution has resulted in the mesolimbic pathway, a brain system that deciphers these natural rewards for us. When we do something pleasurable, a bundle of neurons called the ventral tegmental area uses the neurotransmitter dopamine to signal to a part of the brain called the nucleus accumbens. The connection between the nucleus accumbens and our prefrontal cortex dictates our motor movement, such as deciding whether or not to taking another bite of that delicious chocolate cake. The prefrontal cortex also activates hormones that tell our body: “Hey, this cake is really good. And I’m going to remember that for the future.”

Not all foods are equally rewarding, of course. Most of us prefer sweets over sour and bitter foods because, evolutionarily, our mesolimbic pathway reinforces that sweet things provide a healthy source of carbohydrates for our bodies. When our ancestors went scavenging for berries, for example, sour meant “not yet ripe,” while bitter meant “alert – poison!”

Fruit is one thing, but modern diets have taken on a life of their own. A decade ago, it was estimated that the average American consumed 22 teaspoons of added sugar per day, amounting to an extra 350 calories; it may well have risen since then. A few months ago, one expert suggested that the average Briton consumes 238 teaspoonsof sugar each week.

Today, with convenience more important than ever in our food selections, it’s almost impossible to come across processed and prepared foods that don’t have added sugars for flavour, preservation, or both.

These added sugars are sneaky – and unbeknown to many of us, we’ve become hooked. In ways that drugs of abuse – such as nicotine, cocaine and heroin – hijack the brain’s reward pathway and make users dependent, increasing neuro-chemical and behavioural evidence suggests that sugar is addictive in the same way, too.

Sugar addiction is real

“The first few days are a little rough,” Andrew told me about his sugar-free adventure last year. “It almost feels like you’re detoxing from drugs. I found myself eating a lot of carbs to compensate for the lack of sugar.”

There are four major components of addiction: bingeing, withdrawal, craving, and cross-sensitisation (the notion that one addictive substance predisposes someone to becoming addicted to another). All of these components have been observed in animal models of addiction – for sugar, as well as drugs of abuse.

A typical experiment goes like this: rats are deprived of food for 12 hours each day, then given 12 hours of access to a sugary solution and regular chow. After a month of following this daily pattern, rats display behaviours similar to those on drugs of abuse. They’ll binge on the sugar solution in a short period of time, much more than their regular food. They also show signs of anxiety and depression during the food deprivation period. Many sugar-treated rats who are later exposed to drugs, such as cocaine and opiates, demonstrate dependent behaviours towards the drugs compared to rats who did not consume sugar beforehand.

Like drugs, sugar spikes dopamine release in the nucleus accumbens. Over the long term, regular sugar consumption actually changes the gene expression and availability of dopamine receptors in both the midbrain and frontal cortex. Specifically, sugar increases the concentration of a type of excitatory receptor called D1, but decreases another receptor type called D2, which is inhibitory. Regular sugar consumption also inhibits the action of the dopamine transporter, a protein which pumps dopamine out of the synapse and back into the neuron after firing.

In short, this means that repeated access to sugar over time leads to prolonged dopamine signalling, greater excitation of the brain’s reward pathways and a need for even more sugar to activate all of the midbrain dopamine receptors like before. The brain becomes tolerant to sugar – and more is needed to attain the same “sugar high.”

Sugar withdrawal is also real

Although these studies were conducted in rodents, it’s not far-fetched to say that the same primitive processes are occurring in the human brain, too. “The cravings never stopped, [but that was] probably psychological,” Andrew told me. “But it got easier after the first week or so.”

In a 2002 study by Carlo Colantuoni and colleagues of Princeton University, rats who had undergone a typical sugar dependence protocol then underwent “sugar withdrawal.” This was facilitated by either food deprivation or treatment with naloxone, a drug used for treating opiate addiction which binds to receptors in the brain’s reward system. Both withdrawal methods led to physical problems, including teeth chattering, paw tremors, and head shaking. Naloxone treatment also appeared to make the rats more anxious, as they spent less time on an elevated apparatus that lacked walls on either side.

Similar withdrawal experiments by others also report behaviour similar to depression in tasks such as the forced swim test. Rats in sugar withdrawal are more likely to show passive behaviours (like floating) than active behaviours (like trying to escape) when placed in water, suggesting feelings of helplessness.

A new study published by Victor Mangabeira and colleagues in this month’s Physiology & Behavior reports that sugar withdrawal is also linked to impulsive behaviour. Initially, rats were trained to receive water by pushing a lever. After training, the animals returned to their home cages and had access to a sugar solution and water, or just water alone. After 30 days, when rats were again given the opportunity to press a lever for water, those who had become dependent on sugar pressed the lever significantly more times than control animals, suggesting impulsive behaviour.

These are extreme experiments, of course. We humans aren’t depriving ourselves of food for 12 hours and then allowing ourselves to binge on soda and doughnuts at the end of the day. But these rodent studies certainly give us insight into the neuro-chemical underpinnings of sugar dependence, withdrawal, and behaviour.

Through decades of diet programmes and best-selling books, we’ve toyed with the notion of “sugar addiction” for a long time. There are accounts of those in “sugar withdrawal” describing food cravings, which can trigger relapse and impulsive eating. There are also countless articles and books about the boundless energy and new-found happiness in those who have sworn off sugar for good. But despite the ubiquity of sugar in our diets, the notion of sugar addiction is still a rather taboo topic.

Are you still motivated to give up sugar for Lent? You might wonder how long it will take until you’re free of cravings and side-effects, but there’s no answer – everyone is different and no human studies have been done on this. But after 40 days, it’s clear that Andrew had overcome the worst, likely even reversing some of his altered dopamine signalling. “I remember eating my first sweet and thinking it was too sweet,” he said. “I had to rebuild my tolerance.”

And as regulars of a local bakery in Hershey – I can assure you, readers, that he has done just that.

GE´S GENTLE GIANT ROBOTS: HELPING CREATE CLEANER POWER FOR HUMANS

March 16, 2017

Robots come in many shapes, sizes and iterations. And though most of us envision the gleaming cyborgs or giant armored machines gleaned from decades of science fiction, at GE, robots are helping one of its Distributed Power manufacturing facilities become safer, more cost effective and efficient.

Making its debut in Jenbach, Austria, a different kind of robot is now working alongside its human brethren. A giant robot named Goliath is helping GE staff manufacture some of the most efficient, cleanest, high tech gas engines in the world, faster and safer than ever before. With a power range of 100 kW to 10 MW, they can run on a variety of fuels, including natural gas, biogas, coal seam gases and associated petroleum gases.

The Jenbacher* gas engines produced with Goliath are used in dozens of applications, like hospitals, power plants, greenhouses, residencies and even other factories to produce power, heat and cooling. They are particularly popular for renewable and waste-to-energy, industrial power generation—or any place that faces challenging conditions, difficult fuel gases, or benefits from power that needs to be produced at or near the point of use, anytime and on or off the grid.

GE´s FANUC M2000 900l, i.e. Goliath, may be named after the biblical giant because of size, but it’s is certainly not a fighter. A six-axis industrial robot with a massive reach of just over 15 feet, Goliath was introduced to help gently lift and place tremendously heavy cylinder heads and connecting rods (up to 926 pounds) perfectly during the milling process. And because the colossal behemoth can serve parts for up to three milling machines, plant employees no longer need to touch the parts for handling activities. This allows just one employee to operate an entire portion of the assembly process.

Manufactured in Japan, with programming designed and created by GE internal experts in Austria, Goliath uses sensors to help its operator monitor performance and gather data for continuous improvement. “These advanced analytics not only help improve the factory’s work, but help us to advance the speed of production for the entire facility,” says Martin Mühlbacher, Global Supply Chain site and production leader at GE Power’s Distributed Power business in Jenbach, Austria, “As one of GE´s seven Brilliant Factory showcases our Global Supply Chain team strive to combine lean manufacturing and enhanced productivity with analytics to improve outcomes. Goliath is a big example of that.”

So, next time you’re regaled with tales about futuristic, fantastical robotic technology, remember Goliath and the many other GE giant robots working happily and efficiently to bring electricity to thousands of humans and helping to power everyone with cleaner, greener energy.

GE and Caithness Energy Business Deal

General Electric Co. is nearing a deal with Caithness Energy with a potential value of more than $1 billion to supply equipment for multiple power plants in the U.S.

GE would provide as many as six of its new H-class gas turbines, along with steam turbines and other equipment, the companies announced Wednesday. The pact, covering plants to be developed in 2017 and 2018, is expected to become final by the end of this month.

A deal would be a boon for GE as Chief Executive Officer Jeffrey Immelt reorients it around industries such as energy, aviation and oil. The Boston-based company shed most of its finance and consumer operations while bulking up equipment manufacturing through agreements including the $10 billion acquisition of Alstom SA’s power division.

The so-called HA turbine, a Winnebago-sized unit that is the company’s most efficient, is crucial to GE Power as global population growth drives demand for electricity. GE committed $2 billion to develop the product and help maintain its position as the world’s leading supplier of gas turbines. The manufacturer accounted for about 39 percent of the world market in 2016, followed by competitors Siemens AG and Mitsubishi Hitachi Power Systems Ltd., according to data from McCoy Power Reports.

GE has received orders for 58 HA turbines, not including the six under consideration in the Caithness deal.

Top Customer

Under the agreement being discussed, GE would provide equipment generating as much as 3 gigawatts of electricity, or enough to power about 2.5 million U.S. homes. Orders for the turbines and associated service agreements are expected to be recorded by GE in the next 24 months.

Caithness is poised to become the top customer for the HA turbine, following a 2015 agreement to buy two units for a Pennsylvania plant. That facility, known as Caithness Moxie Freedom, is under development and will go online next year.

Separately, GE signed a pair of agreements with Gas Natural Fenosa valued at $130 million to service equipment in Mexico, including gas turbines manufactured by Siemens and Mitsubishi Hitachi. GE gained the ability to maintain and repair competitors’ products through the Alstom acquisition.

Leaders of GE’s power and renewable-energy businesses are meeting with investors Wednesday in New York to detail the operations.

GE Engineered Equipment Package (EEP) at Pennsylvania CC Power Plant

GE announced an order for a single shaft engineered equipment package (EEP), with a high-efficiency 7HA.02 gas turbine at its heart, to power the Ares EIF’s Birdsboro Power combined-cycle power plant in Birdsboro, Pennsylvania, USA.

With the help of GE’s latest power generation technology and financing from GE Capital, Birdsboro Power is expected to produce 488 MW upon commercial operation in 2019.

“We are pleased to bring this new plant online, which will help continue the shift to cleaner, more cost-effective power in the PJM region,” said Mark Voccola, a partner in Ares EIF, within the Ares Private Equity Group. “The abundance of low-cost natural gas in Pennsylvania means GE’s large, high-efficiency 7HA.02 technology is a great fit, supporting the region’s increased use of natural gas for power generation.”

The 7HA.02 incorporates a 14-stage advanced compressor with 3D aerodynamic foils with superfinish, three stages of variable stator vanes and field-replaceable blades.

“As the largest digital-industrial company, GE is uniquely positioned to bring a complete package of cutting-edge products and solutions to our customers,” said Joe Mastrangelo, president & CEO, GE Gas Power Systems.  “We’re able to provide critical financing to complete this project and deliver the world’s most efficient combined-cycle technology so that Birdsboro can provide more reliable, flexible and efficient power for the people of Pennsylvania.”

In addition to the equipment order, GE, through GE Capital’s Energy Financial Services, co-lead arranged senior secured credit facilities with CIT Bank and Investec, which will be used to support construction and operations of the plant.

The Birdsboro Power project was developed by EmberClear Corp., and the order includes one 7HA.02 gas turbine, one D650 steam turbine, one heat recovery steam generator (HRSG), plant controls and additional equipment. The gas turbine will be manufactured in Greenville, South Carolina, USA, and the steam turbine in Schenectady, New York. The turbines will operate in single-shaft combined-cycle configurations, providing the flexibility required to add highly-efficient, reliable power to the grid as needed.

This project marks GE’s 21st HA unit booked in the U.S. The HA is GE’s largest and most efficient gas turbine. GE’s Power Services has also signed a multi-year services agreement for continued maintenance of the facility’s power generation equipment.

GE 9HA

The 9HA high efficiency, air-cooled gas turbine is an industry leader among H-class offerings, and now the 9HA.01 is at the heart of the world's most efficient combined-cycle power plant. With two available models—the 9HA.01 at 429 MW and the 9HA.02 at 519 MW—customers can easily select the right capacity to meet their generation needs.

INDUSTRY-LEADING OPERATIONAL FLEXIBILITY

Features a fast 12-minute ramp-up from start command to full load, and up to 70 MW/minute ramping capability in a 1x1 configuration or 140 MW/minute in a 2x1 configuration.
