Summary:
Gigablue claims its ocean-based carbon capture technology can save the planet, but scientists are skeptical.
The startup sold 200,000 carbon credits, the largest ocean-based deal to date.
Critics question the lack of transparency and unproven science behind Gigablue's methods.
The carbon credit market is poorly regulated, raising concerns about accountability.
Gigablue's team lacks marine science expertise, relying instead on AI and tech backgrounds.
Gigablue, a startup founded three years ago in Israel, claims to have developed a groundbreaking technology to combat climate change by capturing carbon in the ocean. The company announced the sale of 200,000 carbon credits, a significant milestone, but scientists are skeptical about the efficacy and transparency of their methods.
The Promise
Gigablue's technology involves releasing specially designed particles into the ocean, which they say trap carbon at the seafloor. The company describes this as "harnessing the power of nature" to save the planet. Their vision includes creating "sequestration fields" in the ocean where these particles would be released seasonally.
The Skepticism
Despite the bold claims, outside scientists express frustration over the lack of detailed information released by Gigablue. Key concerns include:
- Unproven Technology: No independent studies confirm the effectiveness of Gigablue's particles in capturing carbon.
- Environmental Impact: The potential effects of these particles on marine ecosystems are unknown.
- Transparency Issues: The company has not disclosed the composition of its particles, citing proprietary reasons.
The Carbon Credit Market
Carbon credits, which represent the removal of one metric ton of CO2, have become a popular way for companies to offset emissions. However, the market is poorly regulated, and some credits have been linked to fraud. Gigablue's sale of 200,000 credits to SkiesFifty, a company investing in greener aviation practices, is the largest ocean-based carbon credit deal to date.
The Team Behind Gigablue
The startup was founded by entrepreneurs with backgrounds in tech and AI, not oceanography or environmental science. Co-founder Ori Shaashua emphasizes their use of AI to model ocean conditions, but critics question their expertise in marine science.
The Science
Gigablue's particles are designed to float, grow algae, and then sink, trapping carbon. However, scientists like Ken Buesseler of Woods Hole Oceanographic Institution doubt the particles can significantly alter ocean chemistry without unintended consequences.
Regulatory Challenges
The lack of regulation in the carbon credit market and ocean-based climate interventions raises questions about accountability. Gigablue's work is currently classified as research, avoiding stricter commercial regulations.
The Road Ahead
Gigablue plans to expand its operations, but without peer-reviewed studies or transparent data, its claims remain controversial. The company's next steps will be closely watched by both supporters and skeptics.
