Categorical Exclusion Determinations: Massachusetts

This Sixth Amended Determination follows the approval of additional funding, extended period of performance, and additional project milestones to support the project team's small-scale research and development activities to use and recycle carbon dioxide (CO2) to extract energy-relevant minerals, including nickel and magnesium, from iron- and aluminum-rich ore through carbonation with CO2, in progress under the Mining Innovations for Negative Emissions Resource Recovery (MINER) program.
Funding will support the project team's small-scale research and development of protein exchange membrane (PEM) water electrolyzers to produce hydrogen by using new materials, designs, and manufacturing processes to overcome high operating and capital costs associated with conventional PEM water electrolyzers.
Funding will support the project team's small-scale research and development of solvent-free methods for manufacturing high-selectivity flow battery membranes using chemical vapor deposition, which could reduce costs and improve performance of redox flow batteries for utility scale grid storage and potential applications for metals separation and desalination.
The U.S. Department of Energy (DOE) is proposing to provide federal funding to Triton Anchor, LLC (Triton) to develop and numerically model a Marine Energy Converter (MEC) and Co-use MEC platform arrays to challenge current anchoring behavior and derive anchor optimizations tailored specifically to omni-directional loading scenarios through physical centrifuge testing.
