- Projects
- ["Generation IV fission technologies offer a commercially realistic chance of achieving that for the first time, allowing coal plants to be repurposed as clean energy sources with comparable electricity output but without carbon emissions or other pollution. Numerous coal plants have already been repurposed for natural gas or biomass combustion. However, natural gas is still a heavy CO2 emitter with volatile pricing and biomass’ land use is simply not sustainable enough to progress beyond a minor net contribution. Generation IV fission reactors, such as Terrestrial Energy’s Integral Molten Salt Reactor (IMSR), operate at the temperature of a coal boiler and are a feasible and highly scalable way to substitute coal combustion for power generation while being cost competitive and capital efficient. This is so much more preferable to decommissioning and dismantling coal plants mid-life and starting from scratch. When coal plants are decommissioned, there are economic and social impacts that reverberate throughout the communities and regions where those plants operated. Jobs are lost, and tax revenues decline. The contribution by coal plants to the tax base is often essential to education and other community services. Alternative sources of power may not materialize for many years, or possibly ever. No community wants to face these types of losses."]
