TerraPraxis 2021 Annual Review

Climate change is an energy problem. We only have 28 years to replace fossil fuels and double our overall energy supply. Our programs could accelerate the reduction of global carbon emissions by repurposing trillions of dollars of existing infrastructure to supply clean, affordable, and reliable energy to billions of people. As you reflect on our 2021 Annual Review, we hope you will be as energized as we are by our success in mobilizing a broad coalition of public and private sector leaders and building momentum for innovative climate solutions.

Repowering the Global Coal Fleet by 2050

TerraPraxis Climate Solution Profile

The TerraPraxis ‘Repowering Coal’ system is a fast, low-cost repeatable strategy to repower hundreds of existing coal plants that would otherwise continue to burn coal, and whose closure is likely to encounter fierce political resistance and cause economic harm to communities. This initiative is designed for radical cost reduction to enable production of reliable, competitive, clean energy, rapidly repowering the 2TW global coal fleet and cutting carbon emissions by 40%. The repowering system transforms coal plants into flexible clean generators, making them better partners for renewables on the grid.

Small Modular Reactors: A new nuclear energy paradigm

Read this if you want to get a quick and realistic understanding of how SMRs could be a game-changer. This new report from the International Atomic Energy Agency (IAEA), available as a pre-print, is the secretariats' view on SMRs. It talks about three major areas (1) Understanding SMRs (2) What will it take to make SMRs a success and (3) What's next for SMRs. The last chapter provides a comprehensive list of IAEA activities to support the SMR deployment.

Investigating Benefits and Challenges of Converting Retiring Coal Plants into Nuclear Plants

Nuclear Fuel Cycle and Supply Chain

This DOE study estimates potential savings for coal plant owners, and benefits for regions: “To replace a large coal plant, nuclear overnight costs of capital could decrease by 15%-35% when compared to greenfield construction, through the reuse of infrastructure. This aligns with TerraPraxis estimates: “Converting plants to run on AMRs will deliver capital cost saving of 28%-35% (compared with new nuclear plant) and 9%-28% reduction in levelized cost of energy.” (WNN, 2022a). This is also consistent with analysis based on Kairos Power SMR design (Bartela et al., 2021), and C2N#3 approach.

Nuclear Power and Secure Energy Transitions: From Today's Challenges to Tomorrow's Clean Energy Systems

IEA's report examines how nuclear energy can help address the crises of energy and climate. The study team acknowledges benefitting from TerraPraxis' work: “the replacement of coal-fired plants with SMRs, such as that of TerraPraxis which aims to prepare standardised and pre-licensed designs supported by automated project development and design tools.” “In today’s context of global energy crisis, skyrocketing fossil fuel prices, energy security challenges, and ambitious climate commitments, I believe nuclear power has a unique opportunity to stage a comeback,” said IEA's head Fatih Birol.

Platforms: Bridging the gap between construction + manufacturing

This publication from Bryden Wood describes an evidence-based design process and manufacture-led construction approach using standardised and repeatable components that could be replicated as an approach across a range of horizontal infrastructure projects in the transport and utilities sectors.

TerraPraxis is partnering with Bryden Wood to design a standardised design for repowering coal plants.
