The U.S.-China Clean Energy Research Center Advanced Coal Technology Consortium The U.S. China Clean Energy Research Center (CERC) is a joint initiative to accelerate research, development, and deployment of clean energy technologies, established and managed by both national governments since 2010. CERC s Advanced Coal Technology Consortium (ACTC) focus its R&D in the following topic areas: Advanced Power Generation, Collaboration and Knowledge Sharing on a Large-scale Demonstration Project, CO 2 Utilization and Storage, and System Analysis and Modeling.
Collaboration and Knowledge Sharing on Large-scale Demonstration Projects The work aims to assist both the U.S. and China in developing largescale CCUS demonstration by accelerating interactive learnings and knowledge sharing from existing and planned large demonstration projects and their associated research.

Task Statements Task 1. Develop & Demonstrate pilot and large-scale integrated CCUS projects (China-side partners lead) Task 1.1. Pre- & Post- Combustion Technology Sharing (Huaneng Lead) Task 1.2. Oxy Combustion Technology Sharing (HUST Lead) Task 2. Knowledge & Information sharing on large-scale CCUS demonstration projects in the U.S. and China (U.S.-side lead-world Resources Institute) g project sponsors, developers, research institutes, and other participants. Post-combustion Pre-combustion Oxy-combustion Utilization & Storage At the project level, the ACTC knowledge-sharing theme should help ACTC members build capacity, increase knowledge stocks, and eventually raise the efficiency and effectiveness of collaboration.

By working with business partners both in the U.S. and China, the Theme II also looks into identifying business opportunities in CCUS and related-industry in the two nations, including understanding the CCUS and coal markets, identifying technology needs, and assessing potential business partners, etc.
Work Progress Both sides signed our knowledge-sharing Joint Work Plan on October 31, 2016. (During our CERC Phase I, we do not have knowledge sharing theme on large-demos.) Since then, we first summarized the lessons from Shenhua Ordos-CO2 Storage Project in the fourth quarter of 2016, then shared the progress on Huaneng IGCC+CCS project and HUST s 35MW Oxy-demo in the first quarter of 2017.. Now, we are working with FutureGen 2.0 to summarize lessons, and will compare them with HUST 200MW Oxy-combustion feasibility study. After this work, we plan to compare the information between Kemper IGCC+CCS and Huaneng IGCC+CCS Project.
Shenhua Ordos CO2-Storage Project Shenhua Ordos Project is China s first integrated CCS demonstration, which has injected around 300,000 tons of CO 2 into saline aquifer in Ordos Basin. It has been a CERC member since the beginning of the first phase. Several strategic factors motivated Shenhua to start this project around 2003-2006. 1. Coal will dominate China s energy mix for a long time; 2. Coal-to-chemicals industry will have a significant growth, which will also have a huge-amount of highly-concentrated CO2 emissions; 3. Capturing CO2 from coal-to-chemicals is relatively cheaper compared with power sector; 4. Shenhua could be leading CCS industry in China and even in Asia for a long time.

Project Layout
CO2 Source The carbon dioxide is sourced from the coal gasification process, in which hydrogen is produced for coal direct hydrogenation. The CO2 is already concentrated (80%) at the inlet of the carbon capture unit. Coal Direct Liquefaction Coal Indirect Liquefaction Coal to SNG CTO Unit ton of CO 2 / ton of oil ton of CO 2 / ton of oil ton of CO 2 / 1000m3 ton of CO 2 / ton of olefin This Shenhua Coal-to-Liquids facility produce 3 million tons CO2 a year; the CCS facility captures less than 1 percent of its CO2 emissions. Total CO 2 Emission Highly Concentrated CO 2 Emission Percentage of Highly Concentrated CO2 Emission 5.56 3.00 54% 6.60 4.88 74% 4.70 2.87 61% 10.00 6.00 60%
CO2 Capture The main capture process includes pressurization, desulphurization, TSA ( temperature swing adsorption)-related dehydration, refrigeration, liquefaction, and distillation. Obtain low-temperature CO 2 at liquid state with purity as high as 99.9%.
Storage Formation
CO2 Injection Injection pressure is 4.8Mpa (fracking pressure is 13 Mpa). Injection temperature is 0.

Regulatory Framework No permitting process at the national and provincial level for CCS projects yet Shenhua only registered this project in the provincial Development and Reform Commission. No guidelines on pore space right Shenhua owns the coal resources in that area; however, no clear government guidelines indicated Shenhua also owns the pore space on that site. No guidelines for Environmental Impact Assessment and Safety So shenhua interviewed experts all around the world to learn how to ensure the environmental integrity. No post-injection management guidelines So now, with 300,000 tons/co2 injected, the plan is still under development.
Economics Overall The full cost (including construction and operating cost) of capturing, transporting, and injecting a ton of CO2 is around 250 RMB/ton(USD30) (If we do include the construction cost, a ton of CO2 costs around 150 RMB/ton (USD20)) The overall capital investment for the CCS unit is RMB 2 Billion. Chinese Ministry of Science and Technology provided RMB 20 Million for R&D surrounding this project. Capital Investment 1.9 Billion (RMB) Purchased Equipment 34 Million (RMB) 18% Purchased Equipment Installation 5.6 Million (RMB) 3% Construction expenses 88 Million (RMB) 46% Materials expenses 28 Million (RMB) 15% Others 32 Million (RMB) 17% Consturction Expenses 1%1% 6% 4% 88% Capture & Transport Injection Underground Storage Safety Other Except the injection pump, all other major equipment are made domestically.
Lessons and Possible Collaboration Areas Technology Improve the efficiency of capture system Understand the economically feasibility to scale up the capture system Site characterization/monitoring Supercritical CO2 Pipeline Policy Incentives No Policy incentives in China at this point to push the CCS projects No major programs to support integrated large-scale CCS Regulatory Framework No permitting process No technical standards for capture, transport, and storage No post-monitoring guidelines
