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.
