GMF Presentation Highlights – CSIRO CMM Case Study

In recent weeks, Methane International has continued to feature presentations from the 2016 Global Methane Forum (GMF). Previously, we covered the GMF’s plenary session on China’s Food Waste and Sludge Management Practices, Challenges, and Lessons Learned and a series of new innovative projects piloting Technologies to Quantify Methane Emissions.

Underground CMM Capture and Emission Reduction

This week, we’re highlighting Dr. Hua Guo’s case study on Underground Coal Mine Methane (CMM) Capture and Emission Reduction. Dr. Guo, Coal Mining Research Director for Australia’s Commonwealth Scientific and Industrial Research Organization (CSIRO), collaborated with staff from Glencore International’s (formerly Xstrata) Bulga Underground Coal Operation outside of Sydney. Studying the Blakefield South Mine, the project team worked to develop a holistic and optimal approach of planning, design and operational control of CMM drainage and ventilation systems to maximize methane capture and minimize fugitive emissions in gassy and multiple seam conditions.

After extensively characterizing the mine complex’ hydrogeology and monitoring emissions, the project team used CSIRO’s COSFLOW model, combined with calibrated field studies, to develop a three-dimensional analysis of the mine strata, hydrology and gas to assess key parameters for the site’s gas drainage, and design an optimal gas drainage plan for the site.

The project team implemented a trial demonstration in a longwall mine including a goaf gas drainage system consisting of underground horizontal holes in the roof and floor seams. The trial resulted in improved gas capture performance, increased drainage efficiency, improved mine safety and coal productivity, and increased methane capture and emission reductions. To learn more about this innovative project, see the above presentation link.

World Bank’s Second Auction Yields 5.7 Million Certified Emission Reductions Guarantees

Last week, the World Bank conducted its second auction in a series of pilots by the Pilot Auction Facility for Methane and Climate Change Mitigation (PAF), an innovative new financing mechanism that aims to attract private sector investment while efficiently reducing emissions.

The PAF incentivizes climate-friendly project developers to capture the methane byproduct by providing a price guarantee for selling carbon credits via a tradeable put option. The purchase of put options enables project developers to hedge the risk of low carbon credit prices that could make the methane capture project unviable. For this pay-for-performance tool, the World Bank will pay project developers only after independent auditors have verified the emission reductions.

Like the World Bank’s first PAF auction held last year, the auction conducted last week targeted eligible landfill, agriculture, and wastewater methane capture projects. Unlike the first auction where participants bid on a carbon credit strike price, the second auction used a ‘forward format’ that fixed the strike price at $3.50/credit while participants bid on the premium price. The premium price paid per carbon credit allows option holders the right to sell credits back to the PAF at $3.50 per credit before 2020. For a more detailed description on how the first and second auctions worked, see these helpful videos.

Twenty-one companies from 12 countries participated in the second auction on $20 million of climate funds. After 10 auction rounds, 9 methane project developers walked away with put options for up to 5.7 million tons of carbon dioxide equivalent (CO2e) emission reductions at a premium price of $1.41 per ton of CO2e. Upon purchasing the put options, auction winners may either sell eligible emission reductions to the PAF, trade the contracts on the secondary market, or let the contracts expire.

GMI is proud to have informed the development of the PAF mechanism, and welcomed its presence on the Global Methane Forum finance panel (see presentation). We look forward to the third auction to take place this Fall.

Global Methane Forum Attendee Survey

Thanks to everyone who attended the Global Methane Forum (GMF). Your participation helped make the Forum one of the Global Methane Initiative’s (GMI’s) most successful events in its history. And now we want to know what we did right and what could have been better.

If you were among the more than 500 people representing 62 countries who attended the Forum and the Climate and Clean Air Coalition’s (CCAC’s) Science Policy Dialogue, this is your last chance to fill out the GMF attendee survey! The survey will remain open through Wednesday, 25 May 2016.

Now that GMI has been re-chartered for another five years, your feedback and continued participation will help to make the Initiative as effective in the next decade as it was in the previous one!

 

GAIL (India) Limited Co-Hosts GMI Oil & Gas Sector Workshop

The GMI Oil & Gas technical team visited GAIL (India) Limited’s (GAIL’s) headquarters in Noida, India, just outside of New Delhi for the 3rd All-India GMI Oil & Gas Sector Workshop, held on 11 March 2016. The event was well-attended, with representatives from two GMI Project Network members: GAIL and the Oil and Natural Gas Company (ONGC). Additional attendees represented oil and gas production, processing, and distribution companies, as well as the public sector, including Cairn India Limited, and Petronet LNG, the Directorate General – Hydrocarbons, FLIR Systems, United Nations Environmental Programme, and the US Embassy in Delhi.

The meeting convened all the major players dedicated to methane mitigation in the oil & gas sector through policy development and technology demonstration and deployment. GAIL generously shared preliminary results from its testing of an innovative retrofit technology designed to cost-effectively capture methane emissions from wet seal centrifugal compressors. Additionally, some of the participating oil and gas production companies expressed interest in joining CCAC’s Oil & Gas Methane Partnership.

All in all, GMI’s Oil & Gas technical team remains impressed by India’s sustained commitment to methane reductions in the oil & gas sector, and looks forward to future collaborations with GMI stakeholders. Special thanks goes to Mr. S.P. Garg, GAIL’s General Manager, and Mr. Arvind Namdeo, GAIL’s Deputy General Manager for Health Safety, and Environment, for their leadership in organizing and convening the very successful event!

 

Global Methane Forum Presentation Highlights: Technology to Quantify Methane Emissions in the Oil & Gas Sector

Over the coming weeks Methane International will continue to feature presentations from the 2016 Global Methane Forum (GMF). Last week we covered the GMF’s plenary session on China’s Food Waste and Sludge Management Practices, Challenges, and Lessons Learned. Up this week, from the Oil & Gas technical session, is the U.S. Department of Energy’s Advanced Research Project Agency – Energy (ARPA-E) and this program’s efforts to develop Technology to Quantify Methane Emissions.

Dr. Bryan Willson, Program Manager for ARPA-E’s Methane Observation Network Technology to Obtain Reductions (MONITOR) Program highlighted ongoing projects working to provide cutting edge leak detection technologies to not only cost effectively locate leaks, but also quantify leaks. Dr. Willson’s presentation highlighted 11 ongoing projects that received awards from ARPA-E: six fixed systems, four mobile systems, and one enabling system. The technologies roughly break down into four categories: Point-Sensing, Aerial, Imaging, and Enabling Technologies. Below is a brief introduction and links for more information.
