China’s Energy – Challenges and Strategies by Professor Ni Weidou Academician, Chinese Academy of Science
“We are running out of the atmosphere faster than we’re running out of fossil fuels”
5 Challenges in China: 1) Huge pressure for energy by 2020. From 2010 to 2020 energy demand will double according to estimates that are under-calculating; 2) Shortage of liquid fuels leading to oil imports of up to 60% by 2015; 3) Severe pollution: 30-40% of China’s territory already suffers from acid rain; 4) Huge increase in Greenhouse Gas (GHG) emissions; 5) Energy supply to 800 million rural residents in the face of rapid urbanization leading to more energy demand as they move because urbanites consume 3.5 times more energy than rural residents.
According to Professor Ni, the only way to mitigate the shortage of liquid fuel is via coal alternatives such as F-T synthetic fuel, Methanol, or DME (dimethyl ether). Coal produced methanol/DME is good for residential use but producing it emits a lot of CO2. A way out is “polygeneration” where the CO2 is captured. The reason wind power is not a viable option for Methanol production is because wind power areas are usually too far away from load centers and grid structures are still very weak in China.
Energy Research at Berkeley by Professor Sastry
CA has a carbon roadmap that is incumbent on currently available technologies.
Need to look at the left side of the equation….WHO CONSUMES? = Transportation, Industries, Buildings.
Buildings: 60% residential 40% commercial. Bldgs matter because they use 72% of all electricity and 55% natural gas.
Big problem is that no one monitors buildings after they are built. Buildings are just assumed to be efficient according to their design plan, not if they actually deliver. To get around this, Berkeley has created “smart dust” where micro sensors are put into buildings to monitor energy efficiency and demand response.
For innovative way to produce methanol and other fuels by the sun (like splitter water by sunlight), check out the HELIOS Initiative (www.climatechange.ca.gov/events/2008_conference/presentations/2008-09-10/Elaine_Chandler.pdf)
Trying to use the most abundant material in the earth’s crust (rust) to create future solar panels.
Envisions a future where fuel manufacturers tell engine/car manufacturers what they need rather than the car telling fuel manufacturers now.
Working on thermoelectrics where waste heat is converted into electricity
Transportation is the no. 1 producer of GHGs in developed nations and is on the rise on China. Berkeley is working with Chengdu to design an affordable transportation system that will use cell phones to map real-time traffic.
Sees nuclear plants as a major player and green cement (cement that can sequester CO2)
