Renewable Energy

Striving to provide more high-quality, clean and low-carbon energy products to the society, the company has been pushing ahead with its new energy development plans and deployed a series of new energy projects. Areas of focus include geothermal energy, gas hydrate, biomass, energy storage, hydrogen fuel and uranium. A “green” growth pattern based on core oil and gas operations and a mix of alternative and renewable sources of energy is taking shape. Meanwhile, “green financing” in the form of “green loans” and “green funds” have been launched to facilitate the transformation to a “greener” growth model.

Geothermal energy

Being an important source of renewable energy, geothermal energy can be used for electricity generation, heating, farming and medical treatment. Today, some sophisticated techniques for low- and moderate-temperature geothermal power generation are available. There are abundant geothermal resources available in Hebei Province of China, where CNPC's Huabei oil province is located. The geothermal heat in Huabei is of low-medium temperature conductive geothermal sources, generally around 90℃.Huabei oil province is endowed with 628.76×1018 joules of geothermal energy, equivalent to 21.4 billion tons of standard coal.

CNPC has been actively promoting the development and utilization of geothermal energy and supporting relative research efforts. We fund demonstration projects in the Huabei, Daqing, Liaohe and Jidong oilfields. So far, a number of geothermal projects have been completed and put into operation. In 2018, Huabei Oilfield has started exploratory drilling of the first geothermal well in Xiong’an, Hebei province.

Biomass energy

Biomass energy is the chemical energy transformed from solar energy and stored in an organism (animal, plant or micro-organism) through photosynthesis, with biomass (living organism) as the energy carrier. Biomass energy is an important type of renewable energy and can be converted into fuel ethanol and bio-diesel by means of sophisticated techniques.

Ethanol fuel

Ethanol fuel, when blended with gasoline, can help to reduce auto emissions and boost the combustion efficiency of engines to a great extent, saving energy and helping to protect the environment.

CNPC has carried out R&D activities with diversified non-grain sources for ethanol fuel without occupying farmland, consuming grain, or damaging the environment. Producing fuel ethanol with sweet sorghum straw is a major breakthrough in this field.

In 2001, Jilin Ethanol Fuel Co., Ltd., a joint venture between CNPC (55%) and Jilin Grain Group (25%) and COFCO (20%), was established.Jilin Fuel Ethanol Co., Ltd. is capable of producing 500,000 metric tons of ethanol fuel and 50,000 metric tons of ethyl acetate every year.

Contributing to the Successful Test Production of Combustible Ice in South China Sea

Natural gas hydrates are also known as "combustible ice". Combustible ice is abundant worldwide, equivalent to twice the amount of other known fossil energy resources in the world. It is mainly distributed in the ocean, and a small amount of it can be found in the tundra on land. Once decomposed, one cubic meter of natural gas hydrates can release 164 to 180 cubic meters of natural gas. It is a high-efficiency clean energy and is hailed as the green energy of the 21st century.

From March to July 2017, CNPC carried out China's first test production program of combustible ice in Shenhu area of South China Sea as the general contractor. It successfully produced gas for 60 consecutive days, with a total production of 309,000 cubic meters of gas, or an average daily production of 5,151 cubic meters. The test production has set two world records: the longest production time and the highest total gas production. Thus, combustible ice was listed as the country's 173rd mineral variety. As a result, we received a congratulatory message from the CPC Central Committee and the State Council.
