Delaware-based technology startup Aternium is advancing plans for a $380 million manufacturing facility in Dover that would produce specialized hydrogen products for industrial customers.
Governor Matt Meyer announced October 30, 2026, that the proposed project has been accepted into Delaware’s JobsFirst Permitting Accelerator.
The facility is planned for Garrison Oak Business and Technology Park in Dover.
According to state officials, the project is expected to create approximately 50 permanent jobs, along with hundreds of temporary construction positions.
Facility Will Produce Hydrogen and Heavy Water
Aternium plans to manufacture high-purity hydrogen and heavy water, a specialized form of water also known as deuterium oxide.
High-purity hydrogen has applications in several industrial processes.
The company intends to supply hydrogen products to customers throughout the Mid-Atlantic region.
Heavy water is used in specialized scientific and industrial applications, including certain activities involving pharmaceuticals, semiconductors, defense technology, and advanced manufacturing.
According to Delaware officials, the proposed facility could help establish additional domestic production capacity for heavy water.
The project remains in development, and the announcement does not identify confirmed production volumes or customer contracts.
Approximately 50 Permanent Jobs Planned
The proposed operation is expected to create approximately 50 permanent positions.
State officials identified engineering, technical operations, manufacturing, and related occupations among the anticipated employment categories.
The announcement describes expected salaries for these positions as being in the low six figures.
However, individual compensation will depend on the positions ultimately established and the company’s employment arrangements.
The project is also expected to generate hundreds of construction jobs during development.
These temporary construction positions are separate from the approximately 50 permanent jobs associated with future manufacturing operations.
No specific recruitment dates or currently available positions were identified in the announcement.
Construction Targeted for Late 2027
Aternium expects construction to begin in late November 2027.
The company estimates that construction will require approximately 18 months.
However, the project remains in its planning phase.
Local, state, and third-party approval processes have not yet begun.
The construction schedule therefore represents the company’s current target rather than a guaranteed completion date.
Project Enters Delaware’s JobsFirst Program
Delaware’s JobsFirst Permitting Accelerator is designed to coordinate regulatory reviews for qualifying development projects.
The program provides participating projects with a single point of contact and coordinates communication among state agencies.
Its objective is to complete complex state permitting reviews within 120 business days while maintaining applicable environmental, public safety, and regulatory requirements.
Acceptance into the program does not constitute final project approval.
Aternium must still complete the required permitting and development processes before construction can proceed.
Startup Previously Received State Support
The October 30 announcement follows an earlier state investment in the company.
In September 2025, Delaware’s Division of Small Business awarded Aternium $1 million through the Delaware Accelerator and Seed Capital Program.
That funding supported the company’s development of clean hydrogen production capabilities.
The earlier award is separate from the newly proposed $380 million manufacturing investment.
The October 30 announcement does not establish a new grant application opportunity for unrelated businesses.
What Local Businesses Should Watch
The proposed development may eventually involve industrial construction, equipment installation, transportation, and specialized manufacturing services.
However, no specific supplier contracts or procurement opportunities were announced.
Businesses interested in potential commercial relationships should monitor future project announcements.
For Dover and Kent County, the proposal represents a potential new manufacturing operation involving a substantial private investment and approximately 50 permanent jobs.
The next milestones will involve permitting, project approvals, construction planning, and progress toward the company’s anticipated late-2027 construction start.
