据世界天然气网10月7日消息 美国液化天然气出口项目开发商NextDecade正在为其拟建的Rio Grande液化天然气项目开发碳中和工艺。
该公司表示，他们已经开发出专利工艺，使用成熟的技术将工厂的二氧化碳当量（CO2e）排放量减少约90%。
NextDecade表示，公司也在探索解决剩余排放问题的方案，以使格兰德河液化天然气实现碳中和。
在NextDecade的最终投资决定前期开发活动中，该公司评估了多种技术解决方案，以确定大幅降低格兰德河液化天然气二氧化碳排放量的商业可行性。
根据这些评估，NextDecade确定碳捕获和储存（CCS）是格兰德河液化天然气最可行的技术解决方案。
该公司认为，将CCS技术与专有工艺相结合，可将其格兰德河液化天然气设施的二氧化碳排放量减少约90%。
虽然NextDecade在这一领域的工作取得了进展，但该公司也在探索解决剩余（约10%）二氧化碳排放的方案。
NextDecade继续致力于达成2021年最终投资决定所需的剩余商业协议。

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 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.
