Largest hydrogen fuel blending in the world coming to Atlanta power plant

Largest hydrogen fuel blending in the world coming to Atlanta power plant

Mitsubishi Power, Georgia Power and EPRI have completed the largest H2 carbon reduction mix.

Mitsubishi Power and Georgia Power have been joined by the Electric Power Research Institute (EPRI) have successfully validated a hydrogen fuel blending with natural gas.

The hydrogen fuel blending was combined in both a partial and full load on an M501G natural gas turbine.

The hydrogen fuel blending took place at the Plant McDonough-Atkinson owned by Georgia Power, in Smyrna, Georgia. The combination took place as a part of a demonstration project. It was the first to have validated a 20 percent H2 blending on an advanced class gas turbine in North America. Moreover, it also represents the largest of its kind to date, with a 20 percent mix, which reduces the carbon emissions by 7 percent when compared with natural gas alone.

“The hydrogen blending demonstration project at Plant McDonough-Atkinson brings us closer to reaching net-zero goals across the industry,” said Mitsubishi Power Americas Executive Vice President and Chief Operating Officer of Power Generation Mark Bissonnette.

Hydrogen fuel blending - Partnership - H2 Testing

Mitsubishi Power collaborated with the largest Southern Company electric subsidiary, Georgia Power, for this new H2 testing. The project is a component of an ongoing commitment to new research and development (R&D) for the development of tomorrow’s energy grid while simultaneously reducing generation fleetwide carbon emissions. Georgia Power had already begun the reduction of its carbon emissions and has cut back by 60 percent since 2007.

The hydrogen fuel blending project took place at the plant about 10 miles from downtown Atlanta.

The Plant McDonough-Atkinson facility has been serving local electricity customers for over 80 years and completed its conversion to 100 percent natural gas in 2012. This led to an expansion to powering as many as 1.7 million homes. The facility operates half a dozen state-of-the-art large-capacity M501G series gas turbines. The turbines deliver high efficiency and high performance. The facility also operates three steam turbines that run in three 2-on-1 combined-cycle configuration blocks.

For this project, Mitsubishi Power finished one of the M501G gas turbine unit’s hydrogen fuel blending with an approximate 265 MW of output. It did so by using some results from a project the New Energy and Industrial Technology Development Organization (NEDO) commissioned. NEDO is the national research and development agency of Japan.

The dry low NOx (DLN) hydrogen fuel blending was successful as high as 20 percent.

The hydrogen fuel blending was deemed successful at a combination as high as 20 percent at the conventional 100 percent natural gas firing temperature, while complying with the existing air permit, and without any impact on maintenance intervals. The project team also showed improved turndown by testing a combination as high as 20 percent H2 at a minimum emissions-compliant load.

Mitsubishi Power supplied complete turnkey surface throughout this project. This included planning, engineering, controls, hydrogen fuel blending hardware, commissioning, and risk management. The company worked with Certarus to obtain and handle the H2 supply. The project built on a foundation of Mitsubishi Power’s experience in H2 combustion and ongoing H2 combustion development for 100 percent hydrogen DLN combustion at its Takasago Works facility in Japan’s Hyogo Prefecture.
