Our product

A fusion power plant, engineered to be deployed nationally and globally.

Longview begins with a demonstrated scientific foundation, and focuses on the engineering required for commercial deployment. The Longview Power Plant is intentionally designed around proven industrial materials, uses existing standard commercial power generation systems, and a modular architecture that can be built, licensed, operated, and replicated in energy markets around the world.

How it works

The demonstrated reaction made repeatable.

NIF proved the reaction with flashlamp lasers firing about once a day. The Longview engine replaces them with modern diode-pumped lasers that can operate continually and can be tuned to follow power demand.

i.

Lasers converge

Diode-pumped solid-state lasers deliver energy onto a target, the modern successors to NIF's flashlamps.

ii.

The fusion fuel ignites

This is the same indirect-drive reaction demonstrated at NIF; fusion energy out exceeds laser energy on target.

iii.

Heat is captured

A lithium blanket surrounds the fusion chamber, capturing fusion energy and producing new tritium fuel feedstock at the same time. This integrated and closed fuel cycle provides a continuous fuel source and supports sustainable long-term operation.

iv.

Power is delivered

Longview pairs its fusion heat source with conventional electricity-generation equipment standard to utilities, enabling reliable, dispatchable power. Longview power plants can be used to repurpose retiring coal burners saving cost while eliminating major carbon dioxide polluters.

The specification

Built to a utility's checklist.

Original design concept, developed and reviewed with eight major U.S. utilities, is now being fully engineered under contract with Fluor.

Building the blocks

A blueprint for commercial fusion, anywhere.

The Longview Power Plant is designed from the outset for widespread deployment. Built around demonstrated fusion physics and conventional energy infrastructure, it is intended to be safe, economical, and adaptable to communities and energy markets around the world.

Every plant and its subsystems and components are modular by design. Components can be replaced, upgraded, and maintained over time during normal operations. This will allow plants to evolve as technologies improve while maximizing reliability, availability, and long-term performance.

Longview will supply the specialized fusion systems that produce fusion energy in each plant, including the lasers, fuel, and fusion engine systems. By delivering these integrated systems, Longview enables a standardized, repeatable approach to building and operating commercial fusion power plants.
