Canadian fusion company General Fusion has signed a framework agreement with Italian renewable energy developer Renexia to explore the deployment of commercial fusion power plants in Italy, marking another step in the race to bring fusion energy out of the laboratory and onto the power grid.

Announced on June 24, the agreement establishes a milestone-based collaboration covering site selection, project development, financing, permitting, construction, and eventual commissioning of one or more power plants based on General Fusion’s Magnetized Target Fusion (MTF) technology. 

According to the companies, feasibility work is expected to begin immediately, with additional phase-one activities planned for later in 2026, subject to future definitive agreements. The announcement was made by General Fusion as part of its commercialization strategy.

Why Italy?

Italy has ambitious decarbonization targets but remains heavily dependent on imported energy, making long-term, reliable low-carbon electricity an important national priority. Renexia, part of Italy’s Toto Group, develops renewable energy infrastructure and has collaborated with General Fusion for several years through the company’s Market Development Advisory Committee.

Unlike a binding construction contract, the newly announced agreement establishes a framework for evaluating whether General Fusion’s technology could eventually be deployed commercially in Italy. If technical and commercial milestones are met, future agreements could cover power plant siting, electricity offtake arrangements, permitting, and construction.

A different approach to fusion

Most high-profile fusion projects rely on either massive magnetic confinement devices known as tokamaks or powerful laser systems that compress tiny fuel pellets. General Fusion is pursuing a different concept called Magnetized Target Fusion, which combines elements of both approaches. 

The system first creates a magnetized plasma, then rapidly compresses it with a lithium liner. According to the company, this approach is intended to avoid the need for superconducting magnets and extremely high-powered lasers while using engineering methods that could ultimately reduce the cost and complexity of commercial fusion reactors. Like every other fusion developer, however, General Fusion has yet to demonstrate a commercially viable power plant.

Progress toward commercialization

The agreement follows several milestones announced by the company over the past two years. In early 2025, General Fusion began operating Lawson Machine 26 (LM26), its fusion demonstration device in British Columbia. The machine is designed to validate key elements of the company’s Magnetized Target Fusion concept at a commercially relevant scale by mechanically compressing plasma inside a lithium liner. 

More recently, company researchers reported experimental evidence of compressional plasma heating during early LM26 campaigns, an important physics milestone that will inform future development, although commercial fusion has not yet been achieved. General Fusion says LM26 is ultimately intended to demonstrate conditions approaching the Lawson criterion, which is the combination of temperature, density, and confinement time required for a fusion plasma to produce net energy.

Fusion’s long road ahead

As companies move beyond laboratory-scale experiments, many are beginning to secure partnerships with utilities, governments, and infrastructure developers to identify potential sites for future commercial power plants.

However, these agreements do not guarantee deployment. Commercial fusion remains one of the most difficult engineering challenges in modern energy research, and developers must still demonstrate sustained performance, economic viability, regulatory compliance, and reliable operation before electricity can be supplied to the grid. General Fusion will first need to prove itself through continued technical validation before any fusion power plant is built.
