A statement from Tellurian said the Memorandum of Understanding (MoU) was signed in Modi's presence.
"Petronet, India's largest LNG importer, will be able to deliver clean, low-cost and reliable natural gas to India from Driftwood. Increasing natural gas use will enable India to fuel its impressive economic growth to achieve Prime Minister Modi's goal of a USD 5 trillion economy, while contributing to a cleaner environment.
"It is an honour to sign the MoU with Petronet in the presence of Prime Minister Narendra Modi. At Tellurian, we look forward to a long and prosperous partnership with Petronet in the Driftwood project," Tellurian's president and CEO Meg Gentle said.
The Driftwood project includes natural gas production, gathering, processing and transportation facilities, along with Driftwood LNG, a proposed 27.6 mtpa liquefaction export facility that will be located near Lake Charles, Louisiana on the US Gulf Coast.
In April, the US Federal Energy Regulatory Commission (FERC) issued the order granting authorisation for Driftwood LNG and the 96-mile Driftwood Pipeline, which will inter-connect the LNG terminal to the US natural gas market.
