Sea-Share™ CDR Subscription
We produce, deploy, and operate wave-driven sea upwelling pumps which mimic and gently accelerate the natural ocean process of CO2 drawdown and removal from the atmosphere.
By subscribing to Sea-Shares, individuals and organizations can make a difference in counteracting climate change, enhancing sea life, and cooling the upper ocean, while getting a head start on SEC compliance.
The Climate Challenge
Ocean Warming
Estimates indicate that the ocean has absorbed more than 90% of the Earth’s warming since at least 1971, mostly near the surface. Ocean warming cuts back the natural upwelling of deeper cold nutrient-rich water, limiting growth of phytoplankton resulting in less CO2 absorbed, and less ocean food for all marine life.
Carbon Emissions
According to the Paris Climate Accord, in order to limit global warming to 1.5°C or 2°C above pre-industrial levels, assuming continued fossil fuel burning in future decades, up to 1000 GT of CO2 must be removed and stored by 2100. CO2 is the primary greenhouse gas (GHG) causing atmospheric and ocean warming worldwide.
Sea Life Decline
Recent scientific studies show a nearly 50% decline in marine life populations between 1970 and 2012. This is due to several factors including ocean warming, as rising ocean temperatures disrupt the ocean’s food chain.
The Sea-Up Solution
Sea Upwelling
Upwelling is the natural process that delivers deeper cold water containing surplus nutrients to the sunlit surface ocean, growing single-cell algae called phytoplankton which absorb oceanic CO2, in turn reducing CO2 in the atmosphere, thereby counteracting the warming. Phytoplankton are the primary ocean food source supporting all higher trophic species - from fish to whales, seabirds to seals!
Upwelling Pumps
Our wave-driven upwelling pumps enhance natural upwelling and deliver critical nutrients to the sunlit surface ocean, growing more phytoplankton. The phytoplankton are eaten or die and sink, sequestering the CO2 and reducing GHGs, leading to a cooler and healthier ocean ecosystem.
Seashare™ CDR Pumps
Carbon dioxide removal (CDR) is a process in which carbon dioxide (CO2) is removed from the atmosphere and stored in the deep ocean. Each Sea-Share pump removes up to 11,000 tons of CO2 per year, thus one Sea-Share Subscription results in up to 1,100 tons of CO2 removal per year.
Your Carbon Removal Opportunity
Investment
Each Sea-Share CDR Subscription owns 10% of one pump's annual operating hours and the corresponding tons of CO2 removed.
Impact
Each Sea-Share CDR Subscription removes an estimated 1,100 tons of carbon dioxide (CO2).
Data
Sensors on the pump's buoy and in the nearby ocean measure CDR. This data is uplinked directly to the Sea-Share subscriber.
Our Technology
Sea-Up provides wave-driven upwelling pumps that harness the power of the oceans to reduce carbon dioxide levels, leading to a cooler and healthier ocean ecosystem.
Sea-Shares offer a pathway for companies to start small, acquainting themselves with marine CDR. Once familiar with the advantages of mCDR, they can quickly expand up to large-scale operations, removing megatons of carbon dioxide per year.
