1 Technology Development to Address Methane Reduction in the Delivery of Natural Gas Non-CO 2 Greenhouse Gas Emissions Workshop Eddie Johnston, Managing Director Delivery Sector August 26, 2008

2 GTI Facilities & Staff > Main Facility: 18-Acre Campus Near Chicago Over 280,000 ft 2 of laboratory space 28 specialized laboratories and facilities > Approximately 250 employees 70% are scientists and engineers Flex-Fuel Test Facility Energy & Environmental Technology Center 2

3 GTI Alignment with Industry Value Chain SUPPLY DELIVERY END USE Needs Provide a secure, stable, competitive domestic energy supply Focus >Unconventional Natural Gas Resources >Gasification of Coal and Biomass >Carbon Capture and Sequestration Address strategic concerns of domestic energy T&D infrastructure > Safety > Pipeline Integrity > Cost Reduction > Efficiency Maintain industrial competitiveness and improve affordability and applicability of gas >Efficiency and environmental >Product development and commercialization >Competitive industry 3

4 GTI Focal Areas for Methane Reduction > Understand the impact of methane emissions for the natural gas industry (3 active projects) > Prevent, detect and mitigate methane emissions from the natural gas system (more than 50 active projects) > Enable the safe and economically viable interchange of renewable gas in the existing infrastructure (7 active projects) 4

5 Improving Key Greenhouse Gas Emission Factors for Natural Gas Distribution Sources Sponsor: Operations Technology Development (OTD) > Update Greenhouse Gas (GHG) emission factors for distribution systems from 1996 GRI/EPA Study Field testing has been conducted by IES to improve the fugitive emission factors for M&R stations and Customer Meters Final Report describing results will be completed Dec More factors to be studied and updated Understanding 5

6 Source Identification of Methane Emissions Sponsor: California Energy Commission > Isotopic Differentiation of Methane Sources in California Demonstrated a novel optical instrument, the GYRO δ 13 CH 4 TM, that makes continuous field measurements of methane isotope ratios Verified that by combining methane mixing ratio and isotope ratio data, a point source of methane emissions, such as landfills, can be differentiated from atmospheric methane Furthermore, demonstrated that methane carbon isotope ratios can be used to assess the proportion of methane admixed from local sources to the atmospheric budget Understanding 6

7 Detecting Unlocatable PE Pipe Sponsor: Operations Technology Development (OTD) Tool to detect PE pipe > Acoustic technology > Easy to interpret data > Accurate markout reduces/eliminates pipeline hits Prevention 7

8 Preventing Excavation Damage Sponsor: OTD / DOT PHMSA > Excavation encroachment notification GPS Technology One-Call violation detection Encroachment warning Prevention 8

9 Rapid Leak Survey Using Laser Sponsor: OTD > Main to meter 15 ft 100 ft Assume plume width is 10 cm = 0.33 ft Thus, there are: V (in MPH) > Driving 30 ft > Laser Detection 9

10 Emergency Shut-off of Blowing Gas Gauge Stopper Purge Stopper Sponsor: OTD >Service Applied Main Stopper -Quick response, less emissions -Fewer service interruptions Mitigation 10

11 Renewable Gas Relevance > Most efficient conversion option for biomass > Potential supply up to 3 Tcf > Utilize existing and gas distribution infrastructure > Greenhouse gas management option; decarbonizing Res/Com sectors > Near-term commercialization potential * Substitute Natural Gas Interchange of Renewable Gas 11

12 Analytical Techniques for Optimal Biomethane Quality Sponsor: GTI Sustaining Membership Program (SMP) > Develop analytical techniques for optimal biomethane quality To investigate and develop analytical procedures for assessment of biomethane quality, for safe interchange with existing supplies Creating techniques for assessment of biomethane quality Developing techniques which support further gas cleanup if needed or gas quality verification Interchange of Renewable Gas 12

13 Guidance to Accept Biogas from Dairy Waste Sponsors: Various: OTD, LDC, Transmission Companies, International LDCs/Transmission > Enabling a Renewable Supply from Dairy Waste Technical review/assessment Analytical testing and data collection Draft Guidance Document preparation Interchange of Renewable Gas pact 13

14 Guidance to Accept Biogas from Landfill and Wastewater Treatment Sludge Conversion Sponsor: DOT/PHMSA > Enabling a Renewable Supply from Landfill and Wastewater Develop a Guidance Document pertaining to the analytical specifications of biomethane in order to secure safe interchange with natural gas supplies Newly initiated and apparent strong support from the Local Distribution Companies Interchange of Renewable Gas 14

15 Biomethane Production: Economic Model Sponsor: NYSEG > Economic Model for Biomethane Production To create a working economic model which can be used to evaluate biomethane production from various biomass sources (dairy waste, landfill, wastewater, agricultural, etc.) Created a instructive manual which details the use of the model and input values, variables and other influential data input parameters Interchange of Renewable Gas 15
