Aqua Metals and MOBY Robotics Partner to Advance Sustainable Deep-Sea Mineral Refining—Key Step Toward U.S. Critical Minerals Independence

MOU Highlights Vision for a Resilient U.S. Critical Minerals Supply Chain

Aqua Metals, a leader in sustainable battery metals recycling, just announced a new Memorandum of Understanding (MOU) with MOBY Robotics, marking a notable expansion of its ambitions: leveraging deep-sea polymetallic nodules as a domestic feedstock for vital metals like nickel, cobalt, manganese, and rare earth elements. By marrying Aqua Metals’ low-temperature AquaRefining™ technology with MOBY Robotics’ autonomous seabed collection capabilities, the two companies aim to strengthen the U.S. supply chain for batteries, magnets, and clean-energy technologies—all while minimizing environmental impact.

Sustainable Refining Technology Targets Market Demand for Battery-Grade Metals

The collaboration arrives at a time when international demand for nickel, cobalt, and manganese is surging. Deep-sea nodules—rocky mineral clusters found on the ocean floor—hold large quantities of these metals, which are critical for electric vehicles, data centers, and grid-scale batteries. Under the new MOU, Aqua Metals will start bench-scale testing later this year to assess if its proprietary AquaRefining™ process can efficiently and sustainably extract high-purity metals from this new feedstock. Importantly, the process also aims to recover rare earth elements (REEs), a critical gap in U.S. manufacturing independence.

Expanding Platform Signals Long-Term Opportunity

This partnership is not Aqua Metals’ first step into the deep-sea minerals market—it marks the company’s second MOU focused on these critical materials. What’s notable is Aqua Metals’ intention to make its AquaRefining™ process “feedstock-agnostic,” adaptable to new mineral sources beyond traditional lithium-ion battery recycling. For investors and industry observers, this indicates a strategy geared toward multi-source, resilient domestic supply chains capable of meeting growing U.S. and global demand.

Environmental Focus Meets Market Opportunity

MOBY Robotics’ CEO, Alex Petersen, emphasized the use of environmentally sensitive autonomous technologies to minimize marine disturbance—key for any sustainable deep-sea mining operation. Combined with Aqua Metals’ near-zero waste, closed-loop refining system, the partnership aims to demonstrate that securing critical mineral independence does not have to come at the expense of environmental stewardship.

Potential Catalysts for Shareholder Value and U.S. Market Leadership

With two deep-sea mineral initiatives underway and a growing portfolio of battery recycling partnerships, Aqua Metals is positioning itself as an early mover in the evolving U.S. critical minerals landscape. While bench-scale testing and commercial feasibility evaluations are early steps, successful integration could reinforce Aqua Metals’ first-mover advantage and open doors in the multi-billion-dollar market for battery and manufacturing materials. Investors should note, however, the standard business risks: no guarantee exists of a finalized agreement or ultimate commercial viability. But this latest partnership underscores Aqua Metals’ role in shaping a circular, resilient, and domestic critical minerals ecosystem.

Key Takeaways

• Aqua Metals and MOBY Robotics aim to pioneer U.S.-based sustainable refining of deep-sea minerals, focusing on nickel, cobalt, manganese, and rare earths.
• Bench-scale testing of AquaRefining™ on polymetallic nodules is set to begin later this year.
• The partnership aligns with growing U.S. efforts to secure domestic critical mineral supply and reduce reliance on overseas sources.
• While still early stage, this collaboration expands Aqua Metals’ technological reach and may help anchor the next generation of clean-tech supply chains.
