Tellurian is committed to supplying energy to the global market with a priority on decreasing urban pollution, reducing worldwide carbon emissions and slowing the pace of climate change. Tellurian is developing natural gas infrastructure efficiently and responsibly, providing consumers with a more reliable, cleaner energy supply and enabling advances in renewable energy alternatives.
We believe natural gas is the most versatile, reliable and available fuel that reduces chronic air pollution when used in place of coal for power production (especially in developing countries) and it:
- Reduces lifecycle carbon emissions by approximately one-half when replacing coal to generate electricity.
- Lowers the carbon footprint of transportation (trucks and ships) by 25% compared to petroleum fuels.
- Virtually eliminates pollutants like sulfur oxides, soot and particulates that cause air pollution and damage human health.
- Complements renewables until they are more economic, reliable, available and where the energy generated can be stored by responsibly developed batteries.
Tellurian is building new infrastructure that improves energy efficiency and apply leading environmental practices to our business, such as:
- Our proposed liquefaction facility, Driftwood LNG, is designed and will be operated to be a near-zero hydrocarbon or methane emission facility.
- Our proposed pipelines will use the latest equipment, technology and monitoring systems, which have been engineered with emission reductions in mind.
- Our upstream business uses “green completions”, also known as Reduced Emissions Completions (RECs). In this process, we capture substantially all the produced gas during well completions – significantly reducing methane emissions.
Driftwood LNG is designed to minimize the potential for leaks and emissions by:
- Using selective catalytic reduction equipment (SCRs) on our turbines that run the refrigeration units, which will reduce nitrogen oxides after combustion and before emission
- Using welded pipes and minimizing flanged connections – where there are metal flanges, we will use spiral-wound gaskets that keep the flange tightly sealed
- Deploying hundreds of gas detectors throughout the facility to serve as early warning devices in the event of a hydrocarbon leak
- Conducting routine maintenance protocols, such as Leak Detection and Repair (LDAR) surveys using optical gas imaging (OGI)
To minimize methane leakage and reduce emissions in our planned pipeline network, Tellurian will:
- Install the latest dry seal technology on all turbine-driven compressors and engine/compressor isolation valves, which are much more efficient at preventing gas leaks
- Install low bleed/intermittent and/or air actuated pneumatic controllers for service valves, which help to maintain a process condition and can isolate sections of the system
- Deploy and actively monitor the pipeline system with real-time SCADA (supervisory control and data acquisition) technology – this includes sophisticated and smart computers that generate real-time signals, which allows the 24/7 permanent staff to shut-in the pipeline or take mitigation actions
- Schedule regular inspections for fugitive emissions
- Perform optical gas imaging (OGI) surveys of transmission and compressor station sites to allow identification of possible leaks thereby reducing the time between the leak identification, mitigation, and repair.
Demonstrating our commitment to action with $2 million pledge
Recognizing that climate change is a global, pressing issue and seeing a gap in research on carbon pricing, Tellurian made a $2 million pledge in 2019 to the Center on Global Energy Policy (CGEP) at Columbia University’s School of International and Public Affairs.
Columbia University has become a leading independent voice on this issue. In the last year, CGEP has released 15 publications, including peer-reviewed reports, working papers, commentaries and op-eds. The center briefed and provided technical assistance to Congressional leaders as they proposed the first bipartisan carbon pricing proposals in a decade. CGEP plans to release key research that outlines how a federal carbon pricing policy interacts with other federal and state regulations to help policymakers make informed decisions about America’s energy policy.
Tellurian has taken and continues to take many actions to minimize methane leakage and reduce emissions in our natural gas production operations. These include:
- Using intermittent or low bleed pneumatic controllers that can maintain a process condition
- Decommissioning all well pad flares
- Shutting in wells to prevent venting if our safety systems detect an unexpected drop in pressure
- Routing gas to sale as soon as practical to avoid flaring on completions
- Performing LDAR surveys utilizing Optical Gas Imaging (OGI) to allow identification and repair of leaks which reduces the time between leak identification, mitigation, and repair.
In addition, Tellurian takes the following precautions in working with fracturing fluids:
- Uses multiple containment layers surround the pipe, including layers of concrete, to assure the production flow and any fracturing fluids pumped do not come in contact with the surrounding earth or water table.
- Captures all hydraulic fracturing fluid and sending to a state-approved facility
- Does not use diesel or BTEX chemicals in our hydraulic fracturing fluids
