Developing a clean energy technology that will transform how the world’s energy is produced

Established in 2013, Terrestrial Energy is an industry-leading technology company committed to delivering reliable, emission-free, and cost-competitive energy with a truly innovative advanced reactor design.

Achieving the world’s climate and energy goals requires nothing less than a complete transformation of how the world’s energy is produced.

Nuclear energy is clean, reliable and vastly scalable. Many experts have concluded that nuclear energy must play a leading role in the clean energy economy of the future.

“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.

Conventional nuclear technology has been the clean energy workhorse for over half a century. It has proven its tremendous capacity to reduce carbon emissions.

However, conventional nuclear technologies, all of which use solid fuel, are struggling against commercial and social challenges.

At Terrestrial Energy, we believe that we can do so much better than technologies chosen over half a century ago.

Terrestrial Energy brought together leading minds in business and technology to quickly commercialize a far superior nuclear technology — one that harnesses nuclear energy’s enormous potential to deliver reliable, cost-competitive and clean energy, developing a nuclear fission technology that will transform how the world’s energy is produced.

The most promising technology to meet the world’s energy needs, a technology that is proven and demonstrated, was selected from many candidates — and Terrestrial Energy went to work to integrate a series of unique innovations to create the Integral Molten Salt Reactor, or IMSR®.

The IMSR® uses a liquid nuclear fuel, a molten salt, a truly innovative approach. It will generate 195 megawatts of electricity per unit. Two IMSR® power plants can power a city the size of Denver.

IMSR® power plants will deliver reliable and clean heat and power. They will be easier to build and finance, less expensive and more versatile than today’s conventional nuclear technologies.

Terrestrial Energy is engaging with world-leading advisors, industrial partners and nuclear regulators. The first commercial IMSR® power plant is expected to come online in North America in the 2020s. With Terrestrial Energy’s industrial partners, hundreds of IMSR® power plants can be deployed.

IMSR® power plants are a clean energy alternative to fossil fuel combustion – they are today’s energy game changer.

Some estimate that to meet the world’s climate and clean energy targets, at least US $1 trillion must be invested every year for the next 30 years — a huge challenge. Considering this, the commercial opportunity for the IMSR® is extraordinary.

Terrestrial Energy is meeting this urgent energy challenge and is leading the way to a bright energy future.
