About Terrestrial Energy

We are developing a breakthrough clean energy technology for 2020s deployment

Our Mission

The global energy market is by far the largest primary market, it supplies over $5 Trillion of energy services per year, 85% of which is from fossil fuels. This market will be fundamentally re-ordered around clean, cost-efficient energy.

This re-ordering is a rare secular transformation but required with increased urgency to achieve ambitious 2050 environmental goals to reduce greenhouse gas (GHG) emissions by at least 80% below currently levels – the so-called “50-80 problem”. This enormous re-ordering has been estimated to require at least $30 Trillion of new capital investment, or approximately $1 Trillion per year; it represents by far the largest single commercial, technology, industrial and investment opportunity today.

Nuclear energy is clean and far more scalable than fossil fuels. Its capacity to decarbonise grids has been demonstrated repeatedly already. We believe that a technology that can harness the enormous energy of the atom and do so while exceeding today’s social expectations of nuclear energy and market needs will play a critical role in re-ordering the global energy market.

We recognize that only one reactor technology among many candidates has been commercialised so far – the pressurized water reactor, which has military origins. We also recognize there are many other candidate technologies that have been researched and demonstrated at national laboratories and universities over the last 60 years, but never been commercialised. If one looks objectively at these alternative candidates through the prism of an informed technician, of today’s market needs and with a disciplined business mindset, one will see a superior commercial reactor technology, a technology capable of playing a role in the re-ordering of the global energy market around a clean cost-competitive energy.

Terrestrial Energy was established in early 2013 to participate in this $30 Tn opportunity with its proprietary Advanced Reactor technology called Integral Molten Salt Reactor technology (“IMSR®” technology). We have taken the most promising alternative technology, one that is proven and demonstrated, and applied a set of proprietary innovations and designed the IMSR®, a reactor with strong industrial and early deployment merit. The IMSR® uses a liquid nuclear fuel, a molten salt, and exemplifies the fundamentally different technology choices the Company is taking to develop a technology with transformative commercial potential.

Our business objective is to complete the engineering and licensing programs for the deployments of our first IMSR® power-plants in Canada and the U.S. by next decade, and to work with our private and public sector partners to demonstrate broadly and before the end of this decade the technology and commercial merit of our IMSR® power plant design.

An IMSR® power-plant is a small modular design that generates 190 MW of power (400MW of heat). It is a Small Modular Reactor, a commercial formulation increasingly desired in many markets today. The Company is undertaking the engineering programs necessary for licensing and construction. It has commenced regulatory action in Canada, an essential step in support of first deployments. Canada’s nuclear regulator, the Canadian Nuclear Safety Commission is internationally renowned and operates a graduated, risk-informed and principles-based regulatory regime; this is most suitable for timely first deployments of IMSR® power-plants.

Since its formation in 2013, Terrestrial Energy has grown its management, engineering and business development teams to include many highly experienced and respected members of the North American nuclear and industrial sectors. The Company has developed relationships with governments, utilities and private investors in support of its mission.  We believe that IMSR® has the potential to be a clean alternative to fossil fuel combustion – to be a truly transformative energy technology, a breakthrough energy technology.
