<strong>Lacq</strong> : main facts<br />
Main characteristics :<br />
• Integrated chain from capture to storage.<br />
• Pilot project : 50 000 t CO2 per year. Maximum Cumulative stored CO2 : 100 000 t.<br />
• Oxycombustion applied on a retroffited boiler (30 MWth).<br />
• Reuse of a gas pipe previously used for gas production (27 kms).<br />
• Storage in a depleted gas reservoir (one producer well converted to injection, 4500<br />
m depth, initial Gas in place 200 Bcf, cumulative production 160 Bcf).<br />
Objectives :<br />
• Prove the technical feasability of an integrated CO2 capture and injection<br />
operation.<br />
• Prepare the scale-up to a 200 MWth boiler.<br />
• Develop and apply a methodology for the relations with the different communities<br />

Surface feedback<br />
ASU (operation & maintenance by AL): no issue / Built and operated by Air Liquid<br />
Oxy-burners (AL equipment): no issue – start-up on air-combustion up to 30% load, then<br />
oxy-combustion up to 100%. Stable flames.<br />
Oxy-boiler: very smooth operation, oxy-boiler efficiency at least as high as air-boiler<br />
efficiency. No operating issues. Only problem is boiler degradation due to retrofit from under<br />
to over atmospheric pressure.<br />
Flue Gas Recycle: no issue<br />
Cooling tower : no issue<br />
<strong>Lacq</strong> compressor (reciprocating – 3 stages – wet): we had corrosion issues (mainly 3rd<br />
stage) because of nitric acid formation (dissolution of NO2 in water) due to liquid water<br />
carry-over from scrubbers towards the suction chambers. Scrubbers have been upgraded<br />
and compressor operating conditions adapted. The compressor now runs corrosion free.<br />
Dryers(AL molecular sieves): no issue<br />
Pipe from <strong>Lacq</strong> to Rousse (existing – 27km – carbon steel): no issue<br />
Rousse compressor (reciprocating – one stage – dry): no issue<br />

Objectives of the storage site monitoring<br />
• To monitor the parameters of injection (flow rate, gas composition)<br />
• To follow the well performance and well integrity<br />
• Related to site integrity, to confirm that gas remains confined in the<br />
reservoir,<br />
• no leak upward out of the reservoir through the well and caprock<br />
• no impact to water resources, to biosphere and human health.<br />
• To check that reservoir behaviour is as modelled, to get information to<br />
calibrate tools, to update predictive models.<br />
• Specific geologic configuration of the storage (deep and low<br />
porosity reservoir, gas into gas, final P

Public and Acceptance<br />

Public awareness : our knowledge in 2006<br />
What did we know on public awareness and position before project<br />
implementation in 2006 ?<br />
SOCECO2 – French National Research Agency project "Assessing CCS technology<br />
support in France on economical and public acceptance stand point"<br />
‣ CCS awareness low in France (6% from poll)<br />
‣ From the 6% knowing the technology, 50% in favor, 50% against<br />
‣ CCS has strong supports from business and public institutions in France<br />
‣ Some organized opposition at national (FNE) and local level (Local community<br />
Association (Coteaux de jurançon) , some position papers from NGO's<br />
‣ No dedicated regulation regarding the CCS in France : Mining code is applied for<br />
the injection of C02 in depleted reservoir.<br />
‣ Identification of stakeholders by a specialized consultant company<br />
Acceptabilty « decision to accept a new technology , a risk »
Public dialog : The key communication tools<br />
‣Public dialog – <strong>Total</strong> approach - transparency policy and open dialog<br />
‣Identification of the main stakeholders<br />
‣Public concertation meetings in 2007 (4 public meetings)<br />
‣Follow-up <strong>Project</strong> Information Committee (CLIS) (10 meetings)<br />
‣Scientific Advisory Committee since 2007<br />
‣Communication Steering Committee has been created in 2007.<br />
‣Scientific collaboration with national French Institut and universities<br />
‣Public information also performed by :<br />
‣Quarterly Information letter (10 letters)<br />
‣Internet sites (Government and <strong>Total</strong>)<br />
‣Movies, Brochures, USB keys<br />
‣Site visits (Schools, Universities, open door events) (2010 1/W / 2011 2/M)<br />
‣Press release (Visit of journalist during the main step of project..)<br />
‣Dedicated Hot line<br />
‣External press releases follow-up specifically the ones against the CCS and<br />
concerning CO2 incident (Weyburn…)<br />
15
Public dialog : The Main Contributing Elements<br />
‣ Start dialog process at the earliest step of the project<br />
‣ A transparency policy in project communication<br />
‣ A great involvement of <strong>Total</strong> managers from the project manager up to the Sustainable<br />
Development Executive Director during the public information meetings<br />
‣ The involvement of a large panel of stakeholders (Scientifics, Authorities, Associations,<br />
citizens…)<br />
‣ The development of didactic communication tools to explain the project<br />
‣ The characteristics of the injection site<br />
‣ The industry background within this area / <strong>Total</strong> credibility in term of gas field exploitation and<br />
HSE results<br />
‣ The strong support of public institutions and local government regarding the CCS industry
Public dialog : Lessons learned<br />
Public acceptance is a continuous process from the time at which the<br />
project is considered to the end of the monitoring period, until responsibility<br />
associated with a storage site is transferred to the public authorities.<br />
‣Set the right level of resources early in the process and perform the full social<br />
relationship management analysis to map out completely the communication plan<br />
‣Importance to take into account the right level and timing to define the stakeholder<br />
management process ( Holidays, electoral periods…)<br />
‣Inform the public with humility and transparency with simple words<br />
‣Company has to keep the leadership of all communication aspects<br />
‣It is still a challenge for our project….
Conclusions : in what fields is the <strong>Lacq</strong> project<br />
contributing to fill knowledge gaps?<br />
Capture:<br />
• Data which are currently gathered will be essential for the upscaling of oxy-fuel<br />
combustion to industrial size.<br />
• It is an important step in the process of maturation of this technology.<br />
Storage:<br />
• Although the storage characteristics are among the most favorable which can be<br />
conceived, this project will bring information on well integrity and reservoir behavior<br />
at low pressure<br />
Integration from Capture to Storage:<br />
• Up to now, no difficulties are met in the operations due to the integration.<br />
Public acceptability:<br />
• The success of the strategy implemented for this project can bring food for<br />
thoughts for other projects but…<br />
Public acceptance is a continuous process during the entire life of a project<br />
It is still a challenge for LACQ project.<br />
