Entergy Nelson 6 Carbon Capture & Sequestration Project

This project was removed from the Institute's LSIP listing in August 2011.

Tenaska and Entergy decided to put the project on hold citing the current uncertain status of national climate policy and weak economy.

Project details

Location: Louisiana, United States of America

Proponent: Tenaska Inc. and Entergy Corporation

Tenaska proposed to retrofit Entergy's existing 585 MW (gross) Roy S Nelson Power Station Unit 6 with equipment designed to capture carbon dioxide (CO₂) through post-combustion capture technology. The power station is a sub-bituminous coal-based plant located at Westlake, Louisiana. The captured CO₂ (approximately 4.4 million tonnes per year) was to be delivered to Denbury Resources' Green Pipeline, which passes approximately five miles from the power station site. Denbury was to use the CO₂ for enhanced oil recovery (EOR) in existing oil and gas fields near the Gulf Coast.

Focus of support

The Global CCS Institute provided AU$825,600 to support CO₂ capture development studies for the retrofit of the Nelson plant.

Reports and outcomes

Tenaska and Entergy are committed to knowledge sharing, including participation in conferences, panels and workshops.
