German fusion energy startup Focused Energy has raised $240 million in Series A funding, bringing its total private funding to $300 million. The company also stated that it had previously secured approximately $200 million in funding, placing it among the larger-scale fusion startups in terms of funding.
RWE led this funding round.
This round of investment was led by the German utility company RWE, with participation from the German Federal Agency for Breakthrough Innovation (SPRIND), Prime Movers Lab, and the European Innovation Council Fund. The company plans to use the funds to advance reactor development and build its first demonstration system, Lighthouse.
Focused Energy, headquartered in Germany, focuses on laser-driven inertial confinement fusion. Its principle involves using lasers to compress fusion fuel, triggering nuclear fusion under extreme conditions and releasing energy.
Referencing the experimental route of the US NIF
The company's proposal references the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory in the United States. This facility remains the first and only experimental system to achieve a controlled nuclear fusion reaction with an output energy exceeding the ignition input energy.
Focused Energy has also recruited key talent from the NIF team. Debbie Callahan, who was involved in fuel target design, joined the company last December as Chief Strategy Officer, and one of his current focuses is simplifying fuel target structures.
The demonstration system is planned to be built on the former site in Germany.
The fuel target used by NIF has a complex structure, and there are approximately 400 experiments per year. If it is to be used for power generation, Focused Energy needs to increase the firing frequency to 10 times per second, or about 864,000 times per day, which places higher demands on manufacturing capabilities and system stability.
To improve efficiency, the company plans to abandon the hohlraum structure used in NIF, which involves converting the laser into X-rays before compressing the fuel pellet, and instead adopt a "direct-drive" approach, allowing the laser to directly compress the fuel pellet. The company hopes to build its first demonstration system, Lighthouse, on the site of a decommissioned nuclear fission power plant in Germany, previously operated by RWE.
Additional information:Funding in the fusion sector has been active this year. TechCrunch noted that Thea Energy completed a $100 million funding round last week, Inertia Enterprises completed a $450 million Series A funding round in February, and Type One Energy announced in January that it had raised nearly $90 million in its $250 million Series B funding round.
