GLOBAL MONITOR
THE BIG PICTURE:
Hydrogen Cofiring at U.S. Gas Power Plants
While natural gas power accounted for 43% of total U.S. power generation in 2023, several state and federal policies
aimed at reducing greenhouse gas emissions are bolstering interest in hydrogen cofiring. These policies include the
Environmental Protection Agency's recently finalized Carbon Pollution Standards, federal production tax credits, and the
federal hydrogen hub program. However, only a handful of natural gas plants have begun integrating hydrogen into
their fuel streams. Operators are exploring three approaches: testing hydrogen cofiring at existing plants, upgrading
turbines to accommodate hydrogen blends, and constructing new plants equipped for hydrogen use. Here are some
recent high-profile projects. Source: POWER/Energy Information Administration.

Intermountain Power Agency
Plant (Intermountain Power
Agency). The Intermountain Power
Project (IPP) Renewed project is
installing a new 840-MW combined
cycle plant in Utah, comprising two
M501JAC gas turbines that will be
capable of utilizing a fuel blend of
30% hydrogen by volume when they
begin operation in 2025. It plans to
transition to 100% hydrogen fuel by
2045 as technology improves.
Long Ridge Energy
Generation Project
(Long Ridge Energy).
This 485-MW plant in
Ohio successfully
tested 5% hydrogen
cofiring in March 2022
using a GE Vernova
7HA.02 gas turbine.
A.J. Mihm Generating
Station (Upper
Michigan Energy
Resources Company).
In March 2023, the
Upper Michigan Energy
Resources Company
conducted a test at its
A.J. Mihm Generating
Station using 25%
hydrogen in one of the
station's three 18.8-MW
Wärtsilä 18V50SG
reciprocating internal
combustion engines.
Brentwood Power Plant
(New York Power
Authority). In September
2022, the New York Power
Authority's Brentwood
power plant cofired a blend
of natural gas on a GE
Vernova LM6000 PC gas
turbine, starting at 5% and
reaching 44% hydrogen by
volume in its 47-MW
peaking unit.
Scattergood
Generation
Station (LADWP).
The Los Angeles
Department of
Water and Power is
seeking to
transition its
existing 778-MW
Scattergood plant
in Los Angeles to a
rapid-response
346-MW combined
cycle system
capable of cofiring
30% hydrogen by
December 2029,
with future plans
to increase that
share to 100%.
Jack McDonough Power
Plant (Georgia Power). In
June 2022, Georgia Power's
Jack McDonough power
plant cofired a fuel blend of
up to 20% hydrogen on an
M501G gas turbine, one of
its 233-MW natural gas
turbines.
Orange County Advanced
Power Station (Entergy). The
1,158-MW Orange County
plant in Texas, expected to
operate by 2026, will cofire up
to 30% hydrogen using two
M501JAC enhanced air-cooled
gas turbines.
Magnolia Power Plant (Kindle
Energy). Kindle Energy LLC is
building the 678-MW Magnolia
Power Plant, composed of a GE
Vernova 7HA.03 turbine, which
is expected to enter service in
2025. Kindle Energy says the
plant could cofire up to 50%
hydrogen.

Hillabee Energy
Center (Constellation
Energy). In May
2023, Constellation
Energy's Hillabee
Energy Center, a
combined cycle plant
in Alabama, tested a
blend of up to 38%
hydrogen on a
Siemens Energy
SGT6-6000G gas
turbine.
DeBary Plant (Duke
Energy). Duke Energy
plans to upgrade one
of DeBary's four
83-MW GE 7E gas
turbines, enabling it to
combust up to 100%
hydrogen (by volume)
to cater to periods of
peak demand. Project
completion is
estimated for late
2024.
