First, the communist party of China (19 big puts forward the goal of building socialist modernization power, which requires energy to support, but not so much energy, how to do? Only seek to improve the efficiency that route %, first in the world, but the per capita energy consumption is less than a third of that in the United States, a little more than half of the OECD countries. China's electricity installed capacity is very breathtaking, now installed capacity has reached 1. 8 billion kilowatts. In the past more than 10 years of power growth created a miracle in the world, but per capita capacity only a little more than the world average. In terms of electricity consumption, China is more than 4000 kw, and the United States is 13000 kw or more, the OECD countries in 7000 to 8000 kw. Mr Dai said: & other; Why should we talk about electricity? Because the electricity is reflect the level of an important indicator of China's modernization. China's economic development is not complete, energy is not up to standard. GDP per capita is only more than $8000, and the OECD countries is more than $thirty thousand. To achieve power, must be supported by energy. If China according to the American model, need 150 times the energy standard, it is impossible to achieve in China. If you want to reach the average in OECD countries, you may need to 116 times. Japan and Germany the two countries' energy efficiency is very high, if you want to reach the levels of these two countries, to 85 times. Achieve power demand for energy increases, it is impossible to meet in China, because there is no guarantee of resources and environment have no energy, the people of the world is difficult to accept, we Chinese people also unbearable. ”
China energy news: future pv to achieve parity with access to the Internet, component efficiency of investment in science and technology is an important driving force, do you think of the current study to what degree?
coastal: crystal silicon is still mainly rely on in the study of enterprise. Especially the last four or five years, photovoltaic enterprise independent innovation ability is very strong. Crystalline silicon latest conversion efficiency has been more than 24%, and this is leading in the world. Most of the past Internet power conversion efficiency at about 18%. Photovoltaic efficiency to 0, you know. 1% is not, the current development trend is very optimistic. And laboratory efficiency and now is not the same as before, now the experiment has not made a few square millimeters, but according to the size of a normal application, can say is the result of industrialization.
coastal: yes. I also did the basic research in the lab, comparing to them, should be sure that they do well. Pull the development of the market driving force is very strong, they have a lot of improvement in technology, many ingenious ways to improve efficiency.
coastal: I am very bullish on thin-film batteries, good prospects. Now it's problem is that conversion efficiency is low, the stability is poorer and have bigger influence on the environment. The dominant on the market at present or in the silicon, probably accounted for more than 90%, but the future in the field of photovoltaic building photovoltaic pv, agriculture, fisheries, film will have a lot of room to grow,
coastal: of preparing now is really the hydrogen & other; Thetime & throughout; . Now do the hydrogen demonstration projects or with hydrogen production from fossil fuels, but the real development of the industry, still need to use renewable energy, hydrogen production, or from the source for hydrogen production technology is unsustainable.
coastal: personally, I think is possible. Renewable energy sources such as wind, solar, water and electricity hydrogen production by the electrolysis of water can be directly as the basis of making fuel cells. Now we put forward a new way of thinking, is combining its and carbon dioxide, into methanol, we call it & other; The sun throughout the fuel &; As transportation, storage, methanol can be like gasoline. The filling station and then put it into hydrogen, hydrogen from the methanol to technology is mature, so that you can solve the hydrogen fuel cells and other System, storage, transport, processing & throughout; The problem. I have been advocating renewable energy, hydrogen production, because the hydrogen fuel cell is a clean technology, but the current hydrogen production technology is not clean. Hydrogen production from coal or natural gas hydrogen production, are unsustainable.
now our first & other; The sun throughout the fuel &; Industrial projects have been launched in last July at the new district in lanzhou, gansu province, is the use of photovoltaic power generation hydrogen production. The next step, we are prepared to datong in shanxi with wind hydrogen production, then may use water and electricity in the south.
