• Warming is happening faster than predicted.
• Cutting emissions and removing CO2 will not be enough.
• We need to rapidly, develop and deploy technologies to cool the planet.

• More than 70% of the earth’s surface is oceans.
• The oceans play a crucial role in combating climate change.
• Around 90% of the heat from climate warming has been absorbed by the
oceans.

• Clouds also play a crucial role in combating climate change.
• Around 67% of the earth’s surface is covered by clouds and they reflect about
23% of heat radiation back into space.
• Increasing cloud reflection by just 3% could reflect enough heat to restore global
temperatures.
• Clouds are the critical cooling mechanism.

Efforts to cool the oceans play a crucial role in combating climate change.
Clouds possess a remarkable ability to cool the oceans by reflecting more heat than
they retain.
Clouds cover 67% of the planet and reflect 30% of heat back into space.
If cloud cover could be increased by 3%, global warming could be stabilised.

Three options being considered
Further Example: Developing a blue carbon portfolio
Concept:
• Add alkaline substances to seawater to
enhance the ocean’s CO2 saturation point
• Carbon molecules flocculate and sink to
the ocean depths
Ocean Alkalinity Enhancement
Concept:
• Apply a voltage across a stack of
membranes to acidify a feed stream and
convert bicarbonates in the water to CO2
• Remove CO2 under vacuum
• Store CO2 in decommissioned wells
Direct Ocean Removal
Concept:
• Co-locate kelp farm with offshore
infrastructure and use platform as a base
for operations, research and possibly
processing
• Sink kelp into ocean depths
Kelp Farming
