Repowering Coal

The TerraPraxis ‘Repowering Coal’ system is a fast, low-cost, and 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.

The Repowering Coal Platform

Repowering existing coal plant infrastructure is the largest single carbon abatement opportunity on the planet and could greatly accelerate the clean energy transition.

Watch these videos to learn how replacing coal-fired boilers at existing coal plants with carbon-free small modular reactors (SMRs), also known as advanced heat sources, creates a fast, low-risk, large-scale and equitable contribution to decarbonizing the world’s power generation.

Watch this video to learn how by replacing coal-fired boilers at existing coal plants with carbon-free small modular reactors (SMRs), also known as advanced heat sources, can quickly transform coal-fired power plants from polluting liabilities facing an uncertain future, into jewels of the new clean energy system.

First, I would like to applaud Kirsty Gogan and Eric Ingersoll on their work around flexible nuclear applications, including heating, hydrogen, and repowering coal plants, with small modular reactors. This kind of ingenuity serves as a reminder: regulators must always be ready for whatever comes our way... we need to know and understand what's coming.

With these technologies now maturing, the next horizon is about their deployment, which is really a bridge to bankability for nuclear. And that’s to me what we’re really talking about here today, which is that we need a phased approach to the deployment of new nuclear that prioritizes speed to market.

In my capacity serving as part of the White House environmental justice advisory council... we're working on a project called the justice 40 initiative where 40% of the investment benefits from any coal fired installation… has to go to communities that are around the immediate region and 40 percent of the jobs have to go to those communities as well. Those benefits have to be seen. Over the next six to 12 months we're working on this regulation process... and making sure that we have kickstarter for nuclear...ready to go in terms of equity, in terms of processing, in terms of operation, and everything in between.

Particularly exciting to see that [TerraPraxis] is developing not just this concept but an actual tool that global coal plant operators will be able to use to assess the viability for their own operations.

Repowering Coal is the largest carbon abatement programme to be designed worldwide


We really believe in this opportunity and so we just said: what do you need and what can Microsoft bring to this?
