Ocean-based carbon capture technology is emerging as a potential solution for reducing atmospheric CO2 levels while producing green hydrogen. LA-based startup Equatic has developed a machine that combines these two critical climate technologies, offering a unique approach to environmental challenges.
How Equatic’s Ocean-based Carbon Capture Technology Works?
Equatic’s system performs two primary functions:
- Removes CO2 from the atmosphere and stores it permanently in the ocean
- Produces green hydrogen as a byproduct of the carbon capture process
This dual-purpose approach addresses two major climate challenges: carbon dioxide removal and clean fuel production. While other companies explore ocean based carbon storage, Equatic claims to be the only one generating green hydrogen simultaneously.
The Role of Oceans in Climate Change Mitigation
The ocean already serves as a natural climate regulator by:
- Absorbing over 90% of heat from greenhouse gas emissions
- Taking in at least 25% of human-generated CO2 emissions
- Providing natural long-term carbon storage capacity
Advantages of Ocean-Based Carbon Storage
According to Carbon180’s science advisor Sifang Chen, this carbon removal offers several benefits compared to land-based alternatives:
- Vast natural storage capacity
- Lower infrastructure requirements than direct air capture
- More cost-efficient storage solutions
- No need for extensive pipeline networks
Environmental Concerns and Challenges
Despite its potential benefits, ocean-based carbon removal faces scrutiny from environmental experts. Mary Church from the Center for International Environmental Law (CIEL) raises concerns about:
- Potential alterations to ocean chemistry
- Changes in marine nutrient levels
- Impact on species abundance
- Effects on marine ecosystems
Current Industry Development
The ocean-based carbon removal sector is experiencing rapid growth:
- Major tech companies like Microsoft and Shopify are investing
- Airlines are showing increased interest
- Tens of millions of dollars in funding are flowing into the industry
- Regulatory frameworks are still developing
Future Implications
As global emissions continue rising, scientists increasingly believe that carbon removal technologies will be necessary to prevent dangerous temperature increases. Ocean-based solutions like Equatic’s system could play a crucial role in this effort, particularly in sectors where green hydrogen could replace fossil fuels:
- Industrial processes
- Shipping
- Aviation
Looking Ahead
While ocean-based carbon removal shows promise, key considerations remain:
- Need for comprehensive environmental impact studies
- Development of regulatory frameworks
- Scale-up potential assessment
- Long-term monitoring requirements
This emerging technology sector requires careful evaluation of both its potential benefits and risks as it continues to develop.
