Industrials

Many industries – legacy and new – sit at the ocean-climate nexus, or are subject to its changing tides. Propeller is invested across industries and stages here, because these markets are ripe for disruption from efficiencies created by technologies in robotics, automation, digitalization, decarbonization and more.

Industries include energy, shipping, transportation, subsea surveying, inspection and more.

Carbon

When it comes to the carbon economy, the ocean is an under-appreciated force. It already stores much of the anthropogenic carbon emitted into our atmosphere, and yet there is great potential to tap into the ocean’s scale, permanence, and additionality.

Propeller is invested across this sector — from novel chemical, biological, and physical pathways for Marine Carbon Dioxide Removal (mCDR) to the enabling layers of persistent sensing, monitoring, and modeling.

Organics

The ocean directly produces and interacts with industries innovating around food, feed, fertilizer and more.

Traditional mariculture is scaling and finding efficiencies while novel marine ingredients find and create new markets.
