Xcimer Energy Secures Additional DOE Funding for Laser Fusion Development

Xcimer Energy has been granted an additional $30.5 million award, bringing its total funding from the Department of Energy's (DOE) Milestone-Based Fusion Development Program to $39.5 million. This non-dilutive funding is contingent on achieving specific milestones and will support technology development, integrated system performance, and commercialization efforts.

Earlier this year, the DOE approved Xcimer's preconceptual design and roadmap for its first commercial fusion power plant, which is projected to be operational by 2035. The new award marks the company's progression into the second budget period of the federally supported fusion energy development program. Additionally, Xcimer received a $4 million award from ARPA-E in 2024, resulting in a total of $43.5 million in non-dilutive federal funding.

The DOE Milestone-Based Fusion Development Program is designed to accelerate the commercial viability of privately funded fusion companies through public-private investment linked to independently verified technical and commercial progress. Darío Gil, the DOE's Under Secretary for Science, stated that the program aims to translate American scientific leadership into commercial capability by leveraging private capital and execution to meet ambitious goals. Gil noted that Xcimer is making progress in laser fusion technology, and this award will help accelerate that work.

Xcimer is developing an excimer laser architecture specifically for commercial fusion power plants. This approach utilizes cost-effective gas lasers and durable gas optics in a two-beamline configuration, designed to deliver megajoule-scale laser energy repeatedly and economically. This differs from conventional methods that often rely on numerous solid-state laser beams and expensive optical components.

Conner Galloway, co-founder and CEO of Xcimer Energy, emphasized the shift from proving the physics to building the industrial technology necessary for commercial fusion energy. He stated that the additional milestone funding will accelerate this work while maintaining private sector investment and risk. Galloway also highlighted the company's focus on developing the laser, manufacturing systems, and supply chain required for commercial laser fusion.

Xcimer's commercial fusion program aims to provide electricity to the grid by the mid-2030s.

Defense Related Applications

In September, Xcimer and RTX announced a partnership to develop directed-energy air defense systems using Xcimer's pulsed laser technology. The collaboration plans to demonstrate the integration and containerization of Xcimer's pulsed lasers with RTX's air defense systems, which could provide new capabilities for the U.S. military against airborne threats. RTX also invested in Xcimer, supporting its laser fusion energy roadmap. Both laser fusion and laser defense share the challenge of developing a pulsed excimer laser that can fire repeatedly and reliably at a low cost per joule, while also being mass-manufacturable and demonstrating efficient operational performance and maintenance.

Danish Decommissioning Submits Proposal for Final Nuclear Waste Repository

On October 2, Danish Decommissioning, a state-owned entity, announced the submission of a proposal for a final nuclear waste repository to the Danish Agency for Civil Security. This action represents a step in Denmark's plans to establish a facility for its nuclear waste.

The proposal builds upon efforts initiated in 2018, following the Danish Parliament's approval of Proposal B 90. This legislation called for geological assessments across Denmark, specifically to depths of 500 meters. The objective of these assessments was to support the development of a deep geological repository. The target for this repository to become operational is 2073.

Swastika Infra Secures ₹615.76 Crore Order for Power Distribution Infrastructure

Swastika Infra Ltd, an EPC player in the power transmission and distribution (T&D) segment and renewable sector, has secured an order exceeding ₹600 crore from the power distribution company MSEDCL. The Letter of Award (LoA) is valued at approximately ₹615.76 crore.

The scope of work includes the development of new substations, HT/LT lines, and distribution transformers. It also covers the augmentation of existing infrastructure, underground cabling, renovation works, GIS mapping, and asset tagging. The project is focused on the Bhandup Zone in Maharashtra and is scheduled for completion within 24 months.
