titutional/Regulatory Aspectsegulatory framework is emerging for deep wellection through extensive interactions with federald state authorities under ongoing projects.wever, the agencies need the resources andndate to expedite regulatory framework.blic utility commissions and policymakers arecoming increasingly gy aware of the technical andonomic issues related to CCS.rough Regional Partnerships and FutureGencess several states have considered long-termbility and ownership issuesere is a strong need for faster progress on theseere is a strong need for faster progress on theseues as we move towards large-scale testing

mary of Trends – We are Now in atical Phase for Future Success of CCSring last few years, CCS has attracted growingerest and support from regional industry andlicymakers, this momentum must continueerging Issues:A major effort to expedite capture technology developmentand integrated capture and storage demonstrationsRegional planning for transport and storage networksDeveloping regulatory, policy, and risk managementframework in parallel l with large-scale l testingtiBuilding public acceptance as we proceed todeployment
