Mitsubishi Heavy Industries Engineering's Recent Records

The Petra Nova Carbon Capture Project is the largest CO₂ capture project in the world targeting coal combustion exhaust gas. It is located in Thompsons, southern Texas, USA, and commenced commercial operation at the end of December 2016.
This project is a large-scale enhanced oil recovery (EOR) project conducted jointly by JX Nippon Oil & Gas Exploration Corporation, the core operating company of the JX Group, and NRG Energy Inc. (NRG), the top independent power producer in the United States, and it is implemented by our joint venture Petra Nova Parish Holdings LLC.

The CO₂ Capture Plants itself consists of exhaust gas pre-processing (desulfurization) equipment, CO₂ absorption and regeneration equipment, CO₂ pumping equipment, and utilities equipment. It captures 4,776 tons of CO₂ per day from coal-fired power generation equipment, which contains a high concentration of CO₂ in its exhaust gas, with a CO₂ capture rate1 of 90%.

This project separates and captures CO₂ from combustion exhaust gas emitted by a coal-fired power plant (WA Parish Generating Station Unit 8), which is owned by the NRG Group and located approximately 60 kilometers (37 miles) southwest of downtown Houston, Texas. CO₂ recovered here is injected into the aging West Ranch Oil Field for the purpose of EOR.

The Petra Nova Carbon Capture Project is a solution that helps to balance environmental and energy needs, in the form of CO₂ capture and EOR at aging oil fields. By reliably operating the CO₂ recovery plant in this project, we intend to both support meaningful business and contribute to sustainable environmental conservation and economic development through active engagement in this field.
