LSB
Industries Inc., Oklahoma City, on May 25 announced that it entered into
agreements with Thyssenkrupp Uhde U.S. LLC, Houston, and Bloom Energy, San
Jose, Calif., to develop a project to produce approximately 30,000 mt/y
zero-carbon or green ammonia at LSB’s Pryor, Okla., facility.
Thyssenkrupp
will develop the engineering design to convert a small portion of Pryor’s
existing conventional ammonia capacity into green ammonia, while Bloom will be
involved in electrolyzer supply.
“We
are very excited to partner with Bloom Energy and Thyssenkrupp Uhde in taking
our first step to becoming a leading supplier of zero carbon or green ammonia
in a unique facility that will have two electrolyzer technologies operating
side by side,” said Mark Behrman, LSB President and CEO. “We believe that being
an early entrant into the green ammonia space will allow us to become a leading
player as the market evolves.
“This
project is very important for LSB and our partners, because in addition to its
initial environmental benefit, it provides a learning opportunity,” Behrman
continued. “With two electrolyzer technologies working together in a real-world
application, we can learn how to effectively develop projects and operate
facilities in this exciting new environment. We view this project as our first
critical step in becoming a major facilitator and participant in the green
ammonia market of the future.”
Green
ammonia will be produced by extracting hydrogen from water using the
electrolyzers powered by a renewable fuel source, such as solar or wind. Since
no fossil fuels are involved in the process, the end-product has no associated
carbon emissions.
Pending results of the feasibility study currently underway, and subsequent Board approval, the project will be constructed in two phases: first with Bloom supplying a 10 megawatt (MW) solid oxide electrolyzer, followed by the installation of an additional 20MW alkaline electrolyzer unit, which will be sourced from a leading manufacturer. Bloom will own, operate, and maintain the solid oxide electrolyzer that, once in operation, will be the largest of its kind in the world.
Once
the second electrolyzer is installed and operational, LSB said Pryor will be
the largest green ammonia production site in North America. Currently, CF
Industries Holdings Inc., Deerfield, Ill., has a 20,000 st/y green ammonia
plant under construction at its Donaldsonville, La. complex (GM April 23, 2021).
The
green hydrogen produced from the electrolyzers as part of the ammonia
production process is expected to qualify for federal incentive programs such
as the production and investment tax credits currently under evaluation by
Congress.
LSB’s
green ammonia news quickly follows an April announcement that it plans to
produce blue ammonia at its El Dorado, Ark. facility (GM April 29, p. 1). Carbon sequestration at the site will allow for
the production of 375,000 mt/y of blue ammonia. Completion of that project is
expected by 2025. Some 450,000 mt/y of CO2 is expected to be sequestered
underneath the El Dorado plant.
LSB
partner Lapis Energy will fund the full capital requirements of the El Dorado
sequestration facility and will pay LSB $1/mt for the CO2. Lapis will receive
the full benefit of current $50/mt tax credit under Internal Revenue Code
Section 45Q. Should the credit move to $85/mt as is proposed, LSB told analysts
on May 4 that an outsized portion of that increase will come back to LSB.
