What do these three have in common?

1

Chevy Bolt Miraloma Substation (80 kWh) 5MW Wind Turbine

They all contribute to reduced

emissions

Their adoption is rapidly accelerating

They all require critical minerals such as

Cobalt, Nickel and Rare Earths

Access to Critical Minerals

Need large amounts of stably sourced minerals. Let’s take a deep dive…

1000x more Cobalt needed

than we can currently recycle!

There’s a reason nobody is doing this yet

• Tough technical challenges

– Less than 10% of ocean has been mapped

– Near 0 °C

– High pressure

– Corrosive

– Subject to temperature swings

1. Non-intrusive, ecosystem-stabilizing deep sea mining techniques

2. Machinery that can operate underwater for the duration of the mining operation

3. Sensors/imaging techniques that work in harsh environments

Ecological Design Constraints

• Newly discovered species in the abyssal plains

• Sediment displacement during mining

• Anthropogenic light, noise and vibration can disturb the sea life

The Collector is a Crucial Component with Room for Innovation

• Needs to collect enough to be profitable

• Vacuum-based collectors

• Minimal contact between collector and sea floor

• Separation of minerals and waste sediment close to the sea floor

• Waste water discharge near the surface (artificial upwelling)

Sensors for Deep Sea Mining

• Rechargeable Autonomous

Underwater Vehicles or Remotely

Operated Vehicles for resource

mapping and monitoring

• Modifying existing subsea

technologies for identifying

surface resources at deeper

depths and for longer durations

Where is the

American Design?

In Conclusion…

•Need reliable access to critical mineral to keep up with

growth in clean energy technologies and achieve energy and

resource independence

• Lots of tech/infrastructure/environmental work needs to be

done

•Make U.S. leader in this space
