Gigablue set out to prove that innovation and scientific rigor can go hand in hand. Their Microalgae Carbon Fixation and Sinking (MCFS) approach required both — continuous improvement in the field and uncompromising data integrity to meet the highest scientific and regulatory standards.
Gigablue and Alcove met at New York Climate Week 2024, and Alcove became a core part of their efforts from the outset. By digitizing every step of their methodology development, from field data collection to quantification modeling, Alcove helped Gigablue establish a compliance architecture built to and shaped by the standards of registries, verifiers, and investors.
“Alcove’s an amazing team that deeply understands CDR developers and builds smart products so you can focus on executing and scaling your CDR project.” – Sapir Markus Alford, CTO at Gigablue
Our platform enabled Gigablue to:
“Alcove’s granular architecture and data interoperability gave us what other platforms couldn’t.” – Sapir Markus Alford, CTO at Gigablue
Alcove equipped Gigablue with the systems to stay audit-ready and scale seamlessly toward credit issuance.
With Alcove, Gigablue accelerated methodology development from an expected two years to just six months, consolidating all audit documentation into a structured, centralized system for faster verification. The team gained greater confidence in compliance tracking and data integrity while reducing manual work and operational risk.
Since adopting Alcove, Gigablue has achieved major scientific and commercial milestones — including signing one of the largest mCDR offtakes to date — while maintaining a consistent focus on data integrity and methodological transparency.
Gigablue is advancing a scientifically-rigorous approach to mCDR using Microalgae Carbon Fixation and Sinking (MCFS). In September 2025, the MCFS methodology was approved by the Puro.earth Advisory Board, paving the way for certification under the Puro Standard. At its core, the MCFS approach leverages the ocean’s ability to uptake more CO₂ from the atmosphere by fixing excess CO₂ into microalgae. This is followed by an efficient and controlled sinking mechanism, locking the carbon in the very deep ocean. The methodology sets a minimum sequestration durability of 200 years, with many sites achieving far longer timescales depending on depth and circulation patterns.
In January 2025, Gigablue signed the largest mCDR offtake to date, agreeing to deliver 200,000 credits over four years. This deal both affirms their ability to sell high-quality carbon credits and signals meaningful market demand for these credits.
