Opportunities for low-cost CO2 storage demonstration projects in China

摘要: Several CO2 storage demonstration projects are needed in a variety of geological formations worldwide to prove the viability capture and as major option for climate change mitigation. China has several low-cost sources at sites that produce NH3 from coal via gasification. At these plants, generated excess amount other purposes (e.g., urea synthesis) is vented relatively pure stream. These would potentially be economically interesting candidates if there suitable nearby. In this study survey was conducted estimate availability modern Chinese coal-fed ammonia plants. Results indicate annual quantities available, per site range 0.6 1.1 million tonnes. The source assessment complemented by analysis possible nearby opportunities storage. were mapped relation China's petroliferous sedimentary basins where prospective reservoirs possibly exist. Four promising pairs sinks identified. Project costs deep saline aquifers estimated each pairing ranging $15–21/t CO2. Potential enhanced oil recovery bed methane near also considered.
