Entergy and Mitsubishi Power Target 50% Cost Cut for Carbon Capture Technology

Entergy and Mitsubishi Heavy Industries Group have signed a memorandum of understanding to develop a roadmap aimed at cutting the overall costs of combined gas turbine and carbon capture technology by half. The non-binding agreement pairs Mitsubishi Power Americas' M501JAC gas turbines with carbon capture technology from Mitsubishi Heavy Industries America, targeting deployment at Entergy's power generation sites across its service territory in Arkansas, Louisiana, Mississippi and Texas. No specific project, facility or budget has been finalised; the MOU establishes a collaborative roadmap rather than a committed deployment.

 

Why Gas Turbines Plus Carbon Capture Is the Pitch

 

The partnership rests on a specific technical premise: pairing a gas turbine combined cycle plant, which burns natural gas efficiently to generate electricity, with carbon capture equipment that removes the resulting carbon dioxide before it reaches the atmosphere. That combination is being positioned as a route to what the industry calls clean firm power, electricity generation that runs continuously regardless of weather, unlike solar or wind, while substantially reducing the emissions gas plants would otherwise produce.

The rationale for using MHI Group specifically is that the company develops both the gas turbine technology and the carbon capture systems internally, rather than the two coming from separate suppliers who would need to integrate their equipment after the fact. The company frames that internal integration as improving project economics, since a single group controlling both halves of the technology stack can standardise designs and reduce the engineering complexity of matching turbines to capture systems built by an unrelated manufacturer.

Why Entergy's Location Matters for Carbon Storage

 

Beyond the technology, the deal's geography is central to its logic. Entergy's operations sit near the largest existing carbon dioxide pipeline network in the United States, and the region offers subsurface geology the companies describe as particularly well suited to safely and permanently storing captured CO2 underground. Carbon capture technology alone accomplishes little without somewhere to put the captured gas afterward, so proximity to both transport infrastructure and viable storage geology is what makes large-scale deployment in this specific region more practical than building similar projects in areas lacking that infrastructure.

That existing pipeline access also shortens the distance between capturing carbon at a power plant and permanently storing it, reducing both the cost and complexity of new transport infrastructure that would otherwise need to be built from scratch, a major cost driver for carbon capture projects in regions without established CO2 transport networks.

What a 50 Percent Cost Target Signals

 

The stated aim of cutting overall costs by half is a significant marker given carbon capture's long-standing reputation as an expensive technology that has struggled to compete economically with unabated gas generation or renewables. Historically, carbon capture retrofits and integrated projects have carried substantial cost premiums that have limited deployment to a small number of demonstration projects rather than widespread commercial adoption. Setting an explicit cost-reduction target, rather than simply committing to build a project at whatever cost results, signals that the companies view standardisation and repeatability, applying the same integrated design across multiple sites rather than custom-engineering each project, as the primary lever for making the economics work.

Mitsubishi Power Americas chief executive Bill Newsom described the collaboration as aiming to create a repeatable model that could accelerate commercialisation of integrated gas turbine and carbon capture solutions, language that reinforces standardisation as the core strategy for reaching the cost target rather than any single technological breakthrough. Entergy's chief operating officer Kimberly Cook-Nelson pointed to scale and standardisation as the keys to making the partnership succeed.

Whether the roadmap translates into an actual committed project at a specific Entergy facility, and whether the partnership's cost-reduction target proves achievable once real engineering and construction costs are tested, will determine whether this MOU marks a genuine step toward commercially viable gas-with-carbon-capture power or remains an early-stage collaboration still working out the details.
