據世界天然氣網10月7日消息 美國液化天然氣出口項目開發商NextDecade正在為其擬建的Rio Grande液化天然氣項目開發碳中和工藝。

該公司表示，他們已經開發出專利工藝，使用成熟的技術將工廠的二氧化碳當量（CO2e）排放量減少約90%。

NextDecade表示，公司也在探索解決剩余排放問題的方案，以使格蘭德河液化天然氣實現碳中和。

在NextDecade的最終投資決定前期開發活動中，該公司評估了多種技術解決方案，以確定大幅降低格蘭德河液化天然氣二氧化碳排放量的商業可行性。

根據這些評估，NextDecade確定碳捕獲和儲存（CCS）是格蘭德河液化天然氣最可行的技術解決方案。

該公司認為，將CCS技術與專有工藝相結合，可將其格蘭德河液化天然氣設施的二氧化碳排放量減少約90%。

雖然NextDecade在這一領域的工作取得了進展，但該公司也在探索解決剩余（約10%）二氧化碳排放的方案。

NextDecade繼續致力于達成2021年最終投資決定所需的剩余商業協議。

NextDecade eyes carbon-neutral Rio Grande LNG

US LNG export project developer, NextDecade is developing processes for its proposed Rio Grande LNG project to be carbon neutral.

The company said it has developed proprietary processes using proven technology to reduce carbon dioxide equivalent (CO2e) emissions at the facility by approximately 90 percent.

NextDecade said it is also exploring options to address the remaining emissions to enable Rio Grande LNG to achieve carbon-neutrality.

Throughout the course of NextDecade’s pre-FID development activities, it has evaluated multiple technical solutions to ascertain the commercial viability of dramatically reducing CO2e emissions at Rio Grande LNG.

Based on these evaluations, NextDecade has determined that carbon capture and storage (CCS) is the most feasible technical solution for Rio Grande LNG.

The company believes that the addition of CCS technology in conjunction with its proprietary processes could reduce the CO2e emissions of its Rio Grande LNG facility by approximately 90 percent.

While NextDecade advances its work in this area, the Company is also exploring options to address the remaining (approximately 10 percent) CO2e emissions.

NextDecade continues to work on remaining commercial agreements needed to achieve a final investment decision in 2021.
