Rio Tinto Sulawesi Nickel Project Island
Despite a number of land disputes, but still want to Rio Tinto Sulawesi Island in Indonesia's nickel project in 2015. The project is 162 million tons of nickel reserves, the initial extraction capacity of 46,000 tons / year capacity will be fully released 10 tons / year.
China's annual output of 100 kilowatts of photovoltaic cells first in the world
China's energy situation and international cooperation in the press conference at the 2008 Beijing International Media Center, the National Development and Reform Commission deputy director of the National Energy Secretary Zhang and foreign reporters will be China's energy situation and the situation of international cooperation.
Zhang said that in 2007 the amount of renewable energy equivalent to 220 million tons of standard coal, primary energy consumption compared to 8.5%. A large proportion of renewable energy is hydroelectric power, China has a hydroelectric power generating capacity of more than 4800 billion kWh, accounting for 16% of generating capacity. Wind power last year added 340 million kilowatts, making the cumulative installed capacity of wind power reached 6.05 million kilowatts.
Solar photovoltaic, now has 10 million kilowatts. Solar water heater's annual production capacity of 23 million square meters, with the amount of 1.2 million square meters, is the world's largest. PV cell production capacity will reach 100 million kilowatts, is the world's largest producer of photovoltaic cells. In addition, we also use biogas, landfill gas facilities in 5000 many medium and large, household biogas digesters has more than 2,700 ten thousand, mostly rural farmers as fuel.
Capacitor battery of a lead body
Headquartered in North Carolina Association of advanced lead-acid batteries (ALABC) in the "people and cars Technology Exhibition 2008" will be displayed on the Ni-MH (Ni-MH) rechargeable battery rechargeable battery lead to the Honda "Insight" cars, and use the battery successfully carried out 160 000 km of test driving. Battery with ALABC members - Furukawa Battery "Ultra Battery". The battery lead rechargeable batteries used in the carbon anode, the performance of the super-capacitor integration.
Ultra Battery in the battery voltage drops, it can lead through capacitor discharge to prevent the battery voltage decreases. Lead battery SOC (state of charge) is low, will lead called sulfation (Sulfation) lead sulfate precipitation, the battery life shortened. The Ultra Battery voltage below 12V will start to discharge the capacitor, resulting in longer battery life, charging performance is improved.
The Insight on the original with the NiMH batteries in series into a 12 Ultra Battery. Voltage is 144V, the current capacity of 8.5Ah. ALABC lead battery used nickel metal hydride batteries than the low price, very life, but the weight is slightly heavier than the nickel-metal hydride batteries.
Furukawa Ultra Battery battery in the future intend to make practical applications as rechargeable batteries and the weak against hybrid cars idle. However, a ban on idling vehicles, most common use of lead batteries in the membrane does not require water soluble glass mat (AGM: Absorbent Glass Mat), compared with the AGM, Ultra Battery cost is higher.
