URUMQI, Dec. 26 (Xinhua) -- The Tarim oilfield branch of PetroChina, China's largest oil and gas producer, said Wednesday they have produced over 28 million tonnes of oil equivalent of crude oil and natural gas in 2019.

The output, which was about 1.76 million tonnes more than that of 2018, included about 5.67 million tonnes of crude oil and about 28.05 billion cubic meters of natural gas, according to the company.

The oilfield's output is expected to reach 30 million tonnes of oil equivalent by 2020 and 36 million tonnes by 2025, the company said.

Located in northwest China's Xinjiang Uygur Autonomous Region, Tarim Basin is the largest petroliferous basin in China and one of the most difficult to explore due to its harsh ground environment and complicated underground conditions.

As China's third-largest onshore oil and gas producer, the natural gas output of the Tarim Oilfield accounted for one-sixth of China's total domestic gas output.

The company said natural gas from the oilfield has benefited about 400 million residents of over 120 cities and more than 3,000 enterprises.

China's Largest Oilfield Produced 57 Million Tons of Oil Equivalent Last Year​

(Yicai Global) Jan. 2 -- Northwest China's Changqing Oilfield, the country's largest, put out more than 57 million tons of oil equivalent of crude oil and natural gas last year, setting an all-time high.

The oilfield had produced 24.2 million tons of crude oil and 41.2 billion cubic meters of natural gas as of 10 p.m. on Dec. 30, according to data published by China Petrochemical, or Sinopec. The oil equivalent figure was up 2.4 million tons annually to mark seven straight years above 50 million tons and beat a 55.5-million-ton record set in 2014.

The oil and gas fields developed at the Changqing oil field in China's Erdos Basin were once deemed worthless by an authorized international agency, but years of exploration and mining have turned it into the country's largest oilfield. It made up 25 percent of all Chinese oil equivalent in 2019, and was the nation's first facility to produce more than 40 billion cubic meters of gas in a single year.

Sinopec also discovered the Qingcheng oilfield in northwestern Gansu province in 2019, which has a proven shale oil reserve of 358 million tons and an estimated reserve of 693 million tons. Output there could reach 1.2 million tons a year in 2019 and quickly rise to 3 million tons in the years to come, the firm said in September.

URUMQI, Jan. 6 (Xinhua) -- The China-Central Asia Gas Pipeline delivered over 47.9 billion cubic meters of natural gas to China in 2019, PetroChina West Pipeline Company said Monday.

The pipeline runs from the border between Turkmenistan and Uzbekistan, passes through Uzbekistan and Kazakhstan and links up with China's West-to-East gas pipeline in Horgos, Xinjiang Uygur Autonomous Region.

China's first transnational gas pipeline, with a total length of 1,833 km and a designed annual gas transmission capacity of 60 billion cubic meters per year, has been operating stably and safely for 10 years since it was put into operation in December 2009.

As of Dec. 31, 2019, 294.6 billion cubic meters of natural gas had been imported via the pipeline, benefitting over 500 million people in 27 provinces, municipalities, autonomous regions, and the Hong Kong Special Administrative Region, the company said.

The natural gas imports via the pipeline account for more than 15 percent of China's total consumption in the same period.

JANUARY 6, 2020 REPORT
Making bio-coal from plant waste to mitigate climate change

A team of researchers affiliated with several institutions in China has found a way to produce bio-coal from plant waste. In their paper published in the journal Science Advances, the group describes their process and how the resulting product could be used.

As the planet continues to warm unabated, scientists around the world seek ways to reduce the amount of carbon dioxide humans pump into the atmosphere. In this new effort, the team in China has found a way to create a type of bio-coal that is much greener than natural coal.

Prior efforts to produce a type of fuel from plant waste have led to the development of bio-oils that can be used as an energy source—but they have several drawbacks. They are corrosive, chemically unstable and are not suitably caloric to be economically viable. However, the team in China found that such oils could be used to make bio-coal, which would be viable. They simply heated the oil to 240 degrees Celsius. Doing so resulted in the formation of a hard, black material similar in appearance to natural coal. Testing showed that the bio-coal could be burned just like natural coal to produce heat to boil water and drive turbines.

The researchers noted that the bio-coal could be made with a variety of ingredients, all of which are generally considered to be biowaste products, such as rice husks, sawdust, wheat or straw, bagasse and soybean straw. They further noted that rice husks worked the best, which, they note, is abundant in many places around the world, and is very inexpensive. Also, because burning the bio-coal releases far less carbon dioxide, the researchers suggest it could be used to replace natural coal. They suggest that replacing the coal burned in China with bio-coal would result in reducing CO2 emissions by 748 million tons, or around 6 percent of China's total output.

The researchers suggest their bio-coal could be used to replace both coal and gases made from plant material. They note their method does not involve using land for growing the biomaterial that could be used for growing food. They also found that it was cleaner than coal in another way—it did not contain zinc, lead, manganese or cadmium, which meant burning it would not emit them into the air. They further note that their bio-coal contained no copper or nickel.

Commercialization remains challenging for hydrogen power in China
By Gao Songya

The lack of specified policies is hindering the commercialization of hydrogen power in China, according to a research released on Wednesday by the China Center for International Economic Exchanges(CCIEE).

Hydrogen generates zero-emission electricity when burned with oxygen. With hydrogen fuel cell vehicles, the cells can directly power the wheels, saving space for cumbersome batteries.

Experts say hydrogen fuel cell vehicles are better at long-distance transportation compared with regular EVs, because hydrogen is available for long-term storage.

China's car maker Foton shows its hydrogen fuel cell bus and truck in collaboration with Toyota and SinoHytech at the 2nd CIIE, November 2019. /Foton

However, as the CCIEE research mentioned, hydrogen power is still categorized by the Chinese authorities as a dangerous chemical, not energy. This requires hydrogen plants and pipelines to be built within certain industrial parks, adding to transportation and production costs.

"We have a hydrogen station running right next to a gas station in Foshan City in Guangdong. That's very convenient. But sadly it's only possible in pilot cities like Foshan," said Zhang Xiaoqiang, executive vice chairman and executive board director of the CCIEE.

Zhang said that the government should start regulating and subsidizing the emerging sector from production, storage and transportation to utilization.

"That's also why investors particularly favored hydrogen fuel cell vehicles in recent years – they were in for EV subsidies by the Chinese government, not hydrogen itself," said Jing Chunmei, leader of the CCIEE research group on hydrogen power.

Shell's hydrogen stations have covered all major cities and towns in California. /InsideEVs

Jing noted that hydrogen power is also good as backup electricity for ships, buildings and households.

Zhang Xiaoqiang said that as EV subsidies are being axed, hydrogen cars are losing their edge.

Mao Zongqiang with Tsinghua University, also vice president of the International Association for Hydrogen Energy, mentioned that China produces 22 million tons of hydrogen annually – already a third of the world's total.

According to Mao, the huge capacity can be 100-percent green in the future, as hydrogen production in China shifts from using fossil fuels to using photovoltaic, solar and wind power.

Coal-rich Chinese province uses rising coalbed methane in 2019
Source: Xinhua| 2020-01-13 22:29:52|Editor: yan

TAIYUAN, Jan. 13 (Xinhua) -- The coal-rich province of Shanxi used an increasing amount of coalbed methane last year as it eyes methane as a source of clean energy.

Shanxi extracted around 7.1 billion cubic meters of methane gas and utilized 6.6 billion cubic meters, with a year-on-year growth of 26.4 percent and 29.6 percent, respectively, according to the Shanxi Institute of Energy.

The province is rich in coalbed methane, a clean energy source similar to natural gas. Shanxi has an estimated 8.3 trillion cubic meters of coalbed methane within 2,000 meters below ground, accounting for 27.7 percent of the country's total.

As of 2015, the accumulative proven reserves of coalbed methane had exceeded 578 billion cubic meters, accounting for about 88 percent of the country's total.

Shanxi has rolled out government plans and policies to speed up the exploration and development of methane gas. The province plans to increase its output to 8.5 billion cubic meters by 2020.

Coalbed methane is a byproduct of coal and a major killer in coal mine accidents. Utilization can help reduce risks in mining, cut greenhouse gas emissions and ease gas shortages.

Scientists Achieve Highly Efficient H2 Production from H2S
By LI Yuan | Jan 16, 2020

Recently, a research team led by Prof. DENG Dehui from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences and their collaborators achieved highly efficient H2 production from electrocatalytic decomposition of H2S via a robust graphene encapsulating metal catalyst.

The study, published in Energy & Environmental Science, provides a promising way for eliminating pollutant hydrogen sulfide and producing green hydrogen energy.

Hydrogen sulfide (H2S) is a toxic by-product of oil and gas production released in enormous quantities, and it is also a potential source of an important green energy carrier, namely, hydrogen gas. The current industrial technology for removing H2S only recovers sulfur from H2S, while the hydrogen constituent is wasted as steam.

The electrocatalytic decomposition of H2S is a kind of mild and efficient method, which produces hydrogen at the cathode and recycles sulfur at the anode simultaneously. However, this technique is hindered by lacking suitable catalysts. Therefore, it's crucial to develop a low-cost, high-efficient and robust electrocatalyst.

Based on the concept of chainmail catalysts firstly proposed by DENG’s group, the researchers developed a kind of new graphene-encapsulated non-precious metal chainmail material as a low-cost and high activity electrocatalyst for decomposition of H2S.

The optimized catalyst drove hydrogen production from decomposing H2S at a much lower potential, which decreased 1.24 V than that of water splitting. Meanwhile, it displayed high activity which was almost twice current density than that of Pt/C, and maintained 500 h stability without decay.

Furthermore, they demonstrated that the superiority of catalyst originated from the modulation of the electronic structure of graphene surface by metal core and nitrogen dopant through the combination of theory and experiment results.

The study was supported by Ministry of Science and Technology of China, National Natural Science Foundation of China, Key Research Program of Frontier Sciences of the Chinese Academy of Sciences, the DNL Cooperation Fund and Collaborative Innovation Center of Chemistry for Energy Materials (2011. iChEM).

Northwest China's Xinjiang Uygur autonomous region transmitted more than 71.24 billion kilowatt hours of electricity to the national grid in 2019, up 1.4 times from the figure recorded in 2018 and reaching a record high in history.

According to a statement released by the State Grid Xinjiang Electric Power Co Ltd on its official website, the electricity generated in Xinjiang was transmitted to 19 provinces, autonomous regions and municipalities in the mainland through the national grid, contributing to the country's economic growth.

Xinjiang has constructed a number of high voltage transmission and transfer power stations since 2010 to further increase its capacity to help transmit the rich electricity resources in the region to other parts of the country.

Last year, the Zhundong-Wannan 1,100 kilovolt power transmission project was officially put into operation after three years of construction, adding a new channel for Xinjiang's electricity exports, the statement said.

The 12 million-kilowatt power transmission channel can transmit between 60 billion and 85 billion kilowatt hours of electricity from Xinjiang to East China's Anhui province every year.

Transmitting Xinjiang's rich electricity resources to the national grid to support the economic construction of other provinces, municipalities and regions has helped promote the transformation of Xinjiang's resource advantage into economic advantages and further optimize the region's energy allocation, the statement said.
