Will China’s government really allow farmers to go online by using the balance of electricity? Moreover, it is a question of distribution style. Besides, farmers are poor, could they afford generators? Please contact me:zhangleixtddd@163.com My surname is Chang Thu, 05 Jul 2007 13:41:56 -0400 http://www.chinadialogue.net/article/summary/1024#comment-3959 http://www.chinadialogue.net/article/summary/1024#comment-3959 China is vast country with great geographical diversity, while agricultural and forestry waste is full of bio fuel possibilities. The government is seeking for new sustainable-developing plans for the rural areas: one of them is to develop biomass-derived resources, like small and distributed cogeneration of heat and electricity, domestic use of biomass, research on biofuels, giving priority to technologies dealing with new energy or renewable energy which also have a broad market prospects. Right now we are putting the plan into action and happy to tell that a project promoting a distributed rural biomass-gas-dedicated small cogeneration system, which also benefits the farmers, is close to success. The system uses materials that are already available such as straw, cotton stalks,etc-gasification equipment imports gas into a small thermal-electricity congenration equipment; burning of the gas generates alternating currents as much as of 380 volts 15,000 watts; The electricity could be used by farmers themselves or combined to a grid, while the rest of heat emission can be used for households or vegetable greenhouses. Technologies utilizing biomass-rich rural waste as such, not only benefit farmers, also help with construction of China's new rural and fitting in with China's current energy policies.

The government is seeking new plans for the rural areas; to develop bio resources, like small and fragmented production of heat and electricity, domestic use of bio materials, biofuels development. This makes more effective use of resources and technologies already available and that which enjoys excellent prospects. Right now we are putting into use a type of small thermal-electricity producer. This uses materials already available such as wheat stalks, cotton stalks--the gas is then fed into a small thermal-electricity contraption to heat it，out comes alternating currents electricity of 380 volts 15,000 watts，that farmers could use themselves or put onto a grid, the resulting heat can be used for households or vegetable greenhouses. This sort of technology makes excellent use of rural waste，it's not just practical and useful for farmer users, it meets the needs of building China's new countryside and fits in with China's energy policies.

Biogas is simple and cheap: just a tank to collect human and animal waste (need at least 2 or 3 animals though to generate enough waste) and then a pipe collects the methane given off and feeds it through to a gas stove in the kitchen, saving on buying and burning coal/wood. Biogas also is a good way to burn off methane, turning it into less dangerous gases (dangerous in the sense of climate change); it is renewable, sustainable and cost efficient with a pay back time of 1-3 years for the inital investment.

It is unavoidable to use fertilizer and pesticide. The use of farm machinery will cause emissions. When we take the whole process into consideration, the use of ethanol fuel is not so helpful as expected in emission cut. Thus, when we try to promote biofuel, we need to have a long-term view to consider the development of the fuel. We should be cautious when considering any related measures and avoid making any irrational decisions under current high energy-demand situation.

But actually, the plant is not yet in operation. Those in charge said the facilities were undergoing maintainance. Everyday, tons of waste is transported to the plant. It was raining as well, so the waste gets wet. Subsidies from the central government is expected to arrive soon to help the plant upgrade its facilities. This plant used to use grain bran to generate power, but due to decreasing grain output, it now uses paper-making waste for power generation. I hope the facilities could be fixed and also financial support from the central government could be delivered soon. Otherwise, the plant will be buried by piles of waste.

It is also healthier for the farmers. There is a 25MW power plant in Shandong Province that is now online and it runs on agricultural waste. That is a huge plant! A lot of power! I wonder how they can organize that much waste being delivered. Trucks must be coming in to deliver it 24 hours a day! In that case, is the amount of fuel and energy they're wasting getting the fuel to the power plant worth it? Biomass is better at a local scale. It has always been done at a local scale, the government should simply make it more efficient. As for biofuels, I think we can go so much further with electric and hybrid cars, that will not rely on any fuel. How can we start this change now? Biofuels are simply just not that efficient in the grand scheme of things, I don't care whether its corn or sugar or cellulosic!

Should they not, perhaps, be balanced with a number of larger biofuel projects which can help China maintain its economic growth?
