Shanghai Technology Innovation take the pulse of the quasi-state strategy
National Science and Technology Award for technological innovation to guide the direction of the "baton" role more clearly. Today, the National Science and Technology Awards 2008 program announced in Beijing, in Shanghai, this year in addition is a "good year", as well as a greater harvest - a new addition this year of the five national awards categories, Shanghai Scientific and Technological Achievements occupy a high winning percentage, shows Shanghai Technology Innovation and the pulse of the national strategy for more and more fit.
It is understood that the National Science and Technology Awards 2008 have a remarkable change is the assessment of the original group of 15, the new addition of the five assessment groups, which are "circular economy and energy conservation," "independent innovation Enterprise "," advanced manufacturing and major equipment "," modern service information "," production safety. "
The first three new groups of all 12 winning projects in Shanghai accounted for 4. Among them, the "circular economy and energy saving," the Top 5 awards, Shanghai Baosteel and fuel cell vehicle project awards; in the "Independent Innovation Enterprises" awards, the Shanghai Zhenhua Port Machinery to become one of the country five winners ; in the "advanced manufacturing and major equipment" areas of Shanghai "supercritical 600 MW combustion turbine" is the one of the two Awards.
Shanghai these four winning projects not only represent four "technical point" of progress, but also aimed to solve the bottleneck of the country much-needed subject to economic, social and industrial development of a supportive role to play.
In this additional "emission reduction" before the awards category, the previous winning projects related to dispersion in manufacturing, energy, environmental protection and other categories; According to analysis, the individual awards of, is to implement the central authorities on energy reduction strategies deployment, to encourage the emergence of innovative technologies.
In the environment "magic" and the dual economic and financial crisis, "forcing", the new energy vehicles are expected to become new economic growth point. Tongji University developed a "fuel-cell cars powered platform" is the term revolutionary new technology that make cars "drink" hydrogen "spit" water to achieve zero emissions, has been successfully applied to a variety of models; last summer, 20 more hydrogen-powered vehicles with the "heart" of the Passat sedan Passat Beijing Olympic Games successful service for our new energy automotive industry took off to grab the opportunity.
National Science and Technology Award winners as "regulars" this year, Baosteel is the country's steel industry and provides a green example. Baosteel developed a real-time monitoring and to scientific control of energy information platform, so do not abide by the rules-product gas, "obey" - the outflow of pollution billowing from the chimney into a valuable secondary energy; the same time, Baosteel built the world's first blast furnace gas as fuel to low calorific value of thermal units for gas to find a stable users. At present, Baosteel blast furnace and coke oven gas has been to achieve "zero emissions", 4 years, through the gas recovery and utilization, and create a direct economic benefit of 5.7 billion yuan, 3.45 million tons of carbon dioxide emissions.
"Baton" orientation is also reflected in the focus on sustainable innovation. New year's "independent innovation enterprises," Review, nominated the project is no longer a contest between the results of a single or technology, the judges pay more attention to the integration of common industrial technology or systemic innovation, and the resulting innovation capability improved. As the team winning the Top 5 one of the units, the Shanghai Zhenhua Port Machinery to "single technological innovation - integrated innovation - the system of innovation" through innovation, top-down culture of innovation and enterprise to persuade the judges to become the first home access to national enterprises in Shanghai for sure.
In the "advanced manufacturing and heavy equipment," the field, from Shanghai is independent design, manufacturing and mass production of 600 MW supercritical thermal power units, has become the main force of China's power grid since 2004, put into operation in more than 100 sets of domestic help In just a few years in China, through the developed countries decades to finish the optimization of thermal power path. Compared to similar units with sub-critical, these units save each year 6.8 million tons of standard coal, 19 million tons of carbon dioxide emissions, 11 million tons of sulfur dioxide. Compared with the imported units, the national production unit completely "picky eaters" - there is no stringent requirements on coal, and power generation efficiency, safety and automation levels have increased.
"In the past, the national technical awards focus more on reporting and review disciplines that, combined with economic and social development needs closely enough; reform and assessment structure, is to promote innovation-driven economy." Talking about changes in national science and technology awards, science and technology Department senior leaders, said the national strategy around the needs of researchers engaged in the State to encourage much-needed break of technical problems, the State Science and Technology Award should be the "baton" role.

Home fuel cell power transmission
Manhattan, Starwood's Sheraton Hotel (Starwoods Sheraton Hotel), World Trade Center site on the new Freedom Tower (Freedom Tower), Verizon's call center on Long Island, northern Sierra Nevada of California wineries, Connecticut Whole Foods supermarket (Whole Foods Market), no association of these places seem, they have one thing in common - are converted to electrical energy using the hydrogen fuel cell-powered, which not only saves energy and reduces greenhouse gas emissions.
Since fuel cells since the 60s into the commercial use, but until today the formation of industrial real. Industry giant United Technologies Corporation (United Technologies) who have NASA (NASA) Apollo spacecraft fuel cell manufacturer, has since been committed to reducing the price of the battery, the company's revenue last year, 54.8 billion U.S. dollars. Fuel Cell Energy (FuelCell Energy) was founded in 1969, is relying on the support of government research funds from the then small company all the way to today, in the past few decades, the company's product cost is too high, not with the grid electricity price competition.
But today, the two with the Department, Connecticut company is to reduce costs, speed up production, and soon will be able to create profits. (United Technologies does not separate the fuel cell sector, announced its financial condition, and fuel cell energy company in the first nine months of fiscal year income of $ 75,000,000, an operating loss of $ 70,000,000.) Senior leaders of the two companies said the scale of effect will reduce product cost, fuel cells will become the logical choice for businesses and households. In addition, earlier this month, the Government rescue package included in the 1100 billion dollars in tax breaks for fuel cells provide a 30% federal tax credit, which will also contribute to development of the industry.
Both companies are expanding, which will create much government leaders and environmentalists have talked about "green jobs." United Technologies fuel cell sector is now (UTC Power) and fuel cell energy company employees 700 and 500, respectively. Fuel Cell Energy CEO Dan Bada (Dan Brdar), said his business this year, the number of fuel cells produced three times last year. UTC President Yang Fan Duoken (Jan Van Dokkum), said: "I think our volume of business a few years will reach 10 billion."
All just a matter of time. Since the 19th century, the core technology to be people to fully grasp. Fuel cell by a chemical process combines hydrogen and oxygen to produce electricity, heat and water. Compared to traditional coal plants or natural gas power plants, fuel cells do not burn energy, so greatly reduced emissions. (United Technologies also provides bus and fuel cell cars.)
But fuel cells or hydrogen in the process of production of the greenhouse gas carbon dioxide emissions. Stationary fuel cell to separate hydrogen from the fuel, before the fuel is natural gas or propane, and now more from landfills, sewage treatment plants or food processing plants received emissions. Bada said: "Now in the U.S., 40% of our company is to rely on biomass gas power stations." Such as the Sierra Nevada Brewery is to use its sewage treatment plant waste methane as a fuel source.
Fewer emissions, power generation more
Mobile users of the fuel cell is its most attractive than the centralized power grid model plus power plants more efficient. In other words, using the same amount of fuel can be issued more power. This is because they can collect and use waste heat to heat water for the building to provide heating or air conditioning; the other hand, centralized power plants is because two-thirds of all energy generated by waste heat released into the air the way, or in wasted during transmission.
UTC President Fanduo Ken said: "No one will waste for every 67 cents to $ 1, but that is the extent of the big power plant waste." Moreover, the fuel cell is mobile, that can be built where the customer , so they do not worry about long-distance transmission of electricity to bring waste.
But the cost is still a big problem. According to Fan Duoken said, UTC Fuel Cells 400 kW new - enough to power a supermarket - the cost per kWh is 11 to 12 cents, assuming a gas price per MMBtu $ 8.50. In New York, New England and California, than the high cost of grid electricity, but in other places, due to mainly rely on thermal power, hydropower and nuclear power, grid electricity is more expensive. If Congress passes climate change bill, the cost of thermal power will increase, making fuel cells more competitive.
UTC has customers in 19 countries installed more than 260 units of stationary fuel cell system, the users, including hotels, hospitals, data centers, wastewater treatment plants and schools, they usually need to secure uninterrupted supply of electricity at the same time want to use waste heat for the building to provide heating, air conditioning and hot water, so the favored fuel cell power generation mode. New York Power Authority (New York Power Authority) has already ordered 12 UTC 400 kW fuel cell, will be installed on the construction of the World Trade Center site Freedom Tower and other buildings.
Fuel Cell Energy companies make a bigger Battery - 1.2 to 2.4 megawatts, can power for large hotels and hospitals - has already sold 80 units, its customers include utilities in Korea, the United States of wastewater treatment plant , hospitals, prisons, and by the Campbell Soup Company (Campbell Soup Company), a subsidiary of the Hartford suburb of Pepperidge Farm, established in a pastry factory. "They asked 24 hours power, full use of waste heat (waste heat can bake cakes bread factory), while corporate culture and promoting sustainable development." Bada said.
So the next time, you the Sierra Nevada's pale ale, chewing Pepperidge Farm goldfish crackers when small, they can calm mind, because you eat these things contain carbon footprint has been reduced a little.

Lithium Battery and Hybrid cars
The New York Mercantile Exchange, August crude oil futures prices for delivery in July 3 145 U.S. dollars a barrel, the highest recorded. In this week, OPEC weekly average oil prices to new highs. In fact, for some time, high oil prices and the resulting series of political and economic and social issues deeply hurt the car manufacturer. In the United States, the three auto makers have cut production of large pickup trucks, SUV, increase energy-saving small cars or crossovers. However, changing the structure of existing products, while car manufacturers have already "obvious": before you have to master the technology of alternative energy vehicles.
"Battery is the core issue." General Motors R & D lab materials laboratory director Mark? Sheet Mubarak said. Have been successful experiences with a certain market hybrid car, the battery technology in deciding the fate of the car key. It is understood that currently includes the Toyota Prius (configuration parameters Gallery) models, including hybrid vehicles use nickel-metal hydride batteries. And the battery technology itself has limitations. Remove the price factors, on the one hand, the decision by the material limits the size of storage capacity, lack of capacity Ni-MH battery life, on the other hand, it can not be extrapolated charging.
Li-ion battery is a high voltage, charge and discharge, long life, fast charging, self-discharge rate, wide operating temperature range, etc., have become the most cars and parts enterprises and the main direction of choice. Data show that, compared to nickel-metal hydride batteries, hybrid electric vehicles using lithium batteries can make the weight decreased by 40% to 50% and the volume reduced by 20% to 30%, energy efficiency has improved to some extent. Optimistic forecast said that in the near future, the vehicle will decrease the cost of lithium batteries to nickel-metal hydride battery 2 / 3.

Silver Zinc laptop batteries
ZPower in a few years ago that people will be able to sell silver-zinc batteries, recently, ZPower company said, and the industry first-line notebook manufacturers have signed a cooperation next year, they can see the silver-zinc battery notebook. ZPower company CEO Dr. Ross E. Dueber will also be present, held recently in Nice, France, Batteries 2008 Conference, will introduce the performance of silver-zinc batteries, environmental and safety advantages.
Compared with lithium-ion batteries, silver-zinc battery life and safety has great advantages. The same capacity, the use of silver-zinc battery notebook battery life can be increased by 40%, if a laptop equipped with a lithium-iron battery can run 2 hours, then the same capacity silver-zinc battery life can be 3 hours. The use of one year period, silver-zinc battery life will not be degraded, while the lithium-ion battery life will reduce about 30%. After one year, silver-zinc battery life degradation is consistent with the lithium-ion batteries.
On the other hand, silver-zinc battery is within the basic framework of the composite polymer zinc anode and silver cathode composition, and also contains water, so the fire does not occur. The silver-zinc batteries are not included within the lithium-ion, all do not need to prevent overheating of the thermal management circuit.
In the green environmental protection, ZPower said, 95% of the components can be recycled, and can also be used to make new batteries, the quality of recycled parts will not be any discounts.
ZPower companies want to replace silver-zinc battery lithium-ion battery, but the current problem is the industry of the silver-zinc batteries also holding off, because the lithium-ion batteries it is also good, although the lithium-ion battery caught fire after the incident, but This did not prevent the industry is to continue to use lithium-ion batteries. In addition, the price of silver-zinc battery, a factor that hinder its development, in order to do the price is very low, on the requirements for production and technical progress, the current silver-zinc battery has not been completed to achieve.
ZPower Which company did not disclose the notebook manufacturers will use silver-zinc battery, may have to wait until next year we will know.
