Shenchu ​​energy storage project

What is the Shenhua CCS demonstration site?

Mapping geomechanical issues into the Shenhua CCS demonstration site The Shenhua CCS demonstration project is the first massive exploration for CO2 capture and geological storage in China.

What does China's Shenhua Group do?

China's Shenhua Group is the largest company of coal production and utilization in the world, especially in coal to liquids and chemicals. With the responsibility for the China's energy security, the company tries to find ways of reducing the reliability on crude oil and pays much attention to the carbon dioxide (CO 2) emission reduction.

How much storage capacity does chenjiacun have?

The entire storage capacity of the Chenjiacun site is estimated to be approximately 0.42 Mt per year with single injection well, based on numerical simulations of a 3.65-year injection with the injection pressure set as 1.5 times hydrostatic pressure.

How safe is the Shenhua Ordos CCS project?

A comprehensive summary about the Shenhua Ordos CCS project is made. A decreasing tendency in the initiation pressure and an increasing injectivity were observed. Challenges remain in terms of developing a more sophisticate site injection model. The CO 2 injection operation at the site is thought to be safe in a storage point of view.

Does coal seam mining affect CO2 storage at chenjiacun?

Numerical simulations (Wu, 2013) were performed to evaluate the potential effect of coal seam mining on CO 2 storage at Chenjiacun. From the simulations, the influencing depth due to coal mining in this area is estimated to be 230 m beneath the mining floor.

Which constitutive model should be used in Shenhua CCS demonstration project?

Based on the potential geomechanical issues and the geological features in the Shenhua CCS demonstration project, it is recommended to choose elastic or elastoplastic constitutive model combined with one-way coupling or partial coupling method.
