Our Story

The next generation of powerful, clean energy. The future is Generation IV nuclear.

At Terrestrial Energy, we’re developing clean, cost-competitive, resilient energy technology that will change how the world produces energy: By utilizing Generation IV nuclear fission technology in a power plant designed for today’s market need, we’ve created the IMSR® power plant, an emission-free, renewable energy source. Achieving the world’s environmental energy goals requires nothing less than completely transforming how the world’s energy is produced – and we are enabling that transformation.

Nuclear energy is reliable, resilient, clean, and vastly scalable. Governments and climate experts consider that nuclear energy must play a leading role in the clean energy economy of the future — especially if we’re going to meet our critical 2050 net-zero emissions targets.

“There is no credible path to climate stabilization that does not include a substantial role for nuclear power… A major expansion of nuclear power is essential to avoid dangerous anthropogenic interference with the climate system this century… We’ve done the math and we can’t power the world without nuclear energy.”

— Open letter to COP 21: Ken Caldeira, Kerry Emanuel, James Hansen, Tom Wigley

The question is: what technology will harness this wonderful and totally unique energy source? For over half a century, we have used conventional nuclear technology. This became a keystone of the clean energy supply, consistently proving its tremendous capacity to reduce carbon emissions. Today, it provides over 31% of the world’s clean energy, second only to hydroelectric power. But in today’s fast-moving energy economy, conventional nuclear technology has been left behind. It is struggling against commercial and social challenges caused by technological decisions made decades ago.

At Terrestrial Energy, we know there’s a much better way, which is why we have taken a fresh look at the many other nuclear technologies researched, developed, trialled, and tested over the last 60 years — and carefully selected one of them which we have redefined into a nuclear power plant designed for today’s market and societal needs.

We brought together leading minds in industry policy, business, and technology to create that superior nuclear power plant technology — one that harnesses the enormous potential of nuclear energy to deliver reliable, resilient, cost-competitive, and clean power. We went to work with well-understood molten salt reactor technology and added a series of unique and patented innovations to create a power plant for broad industrial use: the Integral Molten Salt Reactor, or IMSR® power plant.

IMSR® power plants deliver reliable, resilient, clean heat and power. And as they are simpler and faster to build and easier to finance, these plants will be far less expensive and more versatile than nuclear power plants that use conventional nuclear technologies. One IMSR® power plant will generate 390 megawatts of electricity (195 megawatts per IMSR®) and two are big enough to power a city the size of Denver, Sheffield or Vancouver 24/7 come rain, wind or shine, whether summer or winter. In addition, they can be used equally to make hydrogen at massive scale.

Today, Terrestrial Energy has engaged electric power utilities, nuclear engineering firms, nuclear fuel and component suppliers, industrial partners, and nuclear regulatory authorities and governments. The first commercial IMSR® power plant is expected to be operational in North America in the late 2020s, and with the support of our industrial partners, we can see hundreds of IMSR® power plants being deployed across North America, Europe and the world. IMSR® power plants are the clean energy alternatives to burning fossil fuels. Cost-competitive and versatile, they are the game-changer we need to accelerate our energy transition.

Many energy analysts have estimated that to meet the world’s climate and clean energy targets by 2050, we must invest many trillions of dollars for the next 30 years and starting now. When we take that into consideration as well as the unmatched resilience, sustainability and zero-emissions of nuclear energy, the commercial opportunities for IMSR® power plants are tremendous.

Terrestrial Energy’s IMSR® power plant technology is bringing us so much closer to a clean, peaceful, prosperous, and sustainable energy future where energy generation exists discreetly with little impact on the rich ecology of our planet. Renewable, resilient, and revolutionary: this is the energy future we are creating with IMSR® technology. It is the new dawn to a new energy age — and it’s happening right now.
