Nuclear technology producer, Terrestrial Energy and climate-change fighter TerraPraxis inked an letter of intent to cooperate on a sustainability venture called the Repowering Coal program.
Repowering Coal is a program aiming at integrating sustainable energy sources with existing coal-fired power plant infrastructure. Written by TerraPraxis, the Repowering Coal report was originally launched at COP26 at Glasgow in November 2021, in partnership with Microsoft (NASDAQ:MSFT), the Massachusetts Institute of Technology, Bryden Wood, Schneider Electric and others,
“Terrestrial Energy is a developer of a leading, next-generation, nuclear technology with unique capabilities for Repowering Coal. Terrestrial Energy’s high-temperature reactor technology aligns with the vision and mission of Repowering Coal, namely, the rapid and low-cost deployment of Repowering Coal to replace 2 Terawatts of global coal capacity by 2050,” said Kirsty Gogan, managing director of TerraPraxis.
TerraPraxis is a nonprofit producing scalable solutions for a living planet and human prosperity. Its focuses its attention on the neglected areas of climate change, and specifically, the industrial heat, coal and transport sectors.
Terrestrial Energy, in contrast, develops alternative power operations. More specifically, it’s developing a zero emissions cogeneration plant for global industry using something called Integral Molten Salt Reactor (IMSR) fission technology in a small and modular plant design.
ISMR is a non-light water reactor of the Generation IV class. Also, the ISMR plant is capable of providing for the electrical grid and industrial cogeneration for many energy-intensive industries. A few of these include petrochemical and chemical synthesis for hydrogen and ammonia production.
Repowering Coal and the IMSR
TerraPraxis chose Terrestrial Energy’s IMSR for its Repowering Coal program because of its unique capabilities. It has a high temperature heat supply needed for coal-fired boiler replacement. Also, it’s deployment is quick and at scale and will replace 2 Terawatts of global coal capacity by 2050. Additionally, the two companies will work on a standardized systems interface between the IMSR and coal-fired plat systems..
“TerraPraxis is a visionary leader in climate and energy, focused on practicable, energy-transition pathways. Repowering coal with Generation IV nuclear can decarbonize a difficult-to-abate part of the energy system rapidly and cost-effectively,” said Simon Irish, CEO of Terrestrial Energy.
A U.S. Department of Energy (USDOE) study released in September 2022 indicated there were 300 coal-fired plants in the US that were candidates for the program. In addition, the study indicated 80 per cent of retired and coal power plant sites possess the characteristics required to host an advanced nuclear reactor. The total is 260 gigawatts of electricity located at over 300 sites. The partnership expands to repowering coal plants across the world, which is potentially an extra two Terawatts.
