Novel methodology for carbon removal from ocean microalgal blooms announced

News | December 5, 2023 | By:

EcoEngineers, a clean energy consulting, auditing, and advisory firm, has developed a rigorous crediting methodology to quantify and verify carbon dioxide removals (CDR) for Brilliant Planet, a leader in high-integrity, permanent carbon removal. The methodology provides a robust framework for developing greenhouse gas (GHG) removal projects using Brilliant Planet’s award-winning specialized system, which cultivates and sequesters carbon from marine microalgal blooms.

The essence of this methodology lies in transforming marine microalgae into a vehicle to remove atmospheric carbon dioxide. Microalgae are tiny, unicellular plants that live in fresh water or marine ecosystems. Microalgae are capable of photosynthesis and convert atmospheric carbon dioxide into biomass.

Brilliant Planet’s novel approach employs the microalgal capacity to efficiently generate biomass to capture atmospheric carbon that is subsequently sequestered. In recognition of its Supervisory Control and Data Acquisition (SCADA) automation and control philosophy for its coastal, microalgal cultivation system, Brilliant Planet received the Robotics & Automation Award 2023 for “Innovation in Sustainability.”

Per the methodology, carbon credits will be generated for each metric ton of CO2 removed from the atmosphere by controlled algal blooms in land-based ponds, which are dried and subsequently sequestered in permanent, purpose-built landfills. All credits issued will be net of any identified project emissions and must meet durability requirements for more than 1,000 years of storage.

“Brilliant Planet’s approach to CDR has the potential to be a notable tool in the fight against climate change,” said David LaGreca, EcoEngineers’ director of voluntary carbon markets. “There is a lack of standardization in measuring the impact of CDR projects. For that reason, we crafted the methodology in accordance with ISO 14064-2:2019.”

“The methodology brings us one step closer to third-party verification of our process, which is good news for climate change,” said Dr. Raffael Jovine, co-founder and chief scientist, Brilliant Planet. “With our technology, we can store biomass in a sustainable and cost-effective manner, while minimizing environmental impacts, fugitive gas leaks, and the remineralization of CO2. This new method incorporates measures to anticipate future environmental changes, ensuring its long-term effectiveness.”

GHG benefits are credited exclusively for the CO2 content sequestered within the algal biomass. At the time of harvest, the rapidly growing microalgal cells are meticulously separated from seawater, promptly processed, and dried to prevent any potential bacterial remineralization, predation, or ecosystem recycling. The resulting extra-dry (>92% dry) and hypersaline (>40% salt) salt-biomass composite is then consolidated and buried in a shallow landfill located on or near the project site. The landfill is designed to prevent groundwater intrusion, and is lined and capped with a geomembrane, creating a permanent biomass-storage structure. The site is continuously monitored to ensure a minimum stability period of 1,000 years with no resulting decomposition.

“This methodology is highly adaptable, focused initially on describing requirements for projects in coastal desert regions,” added LaGreca. “Notably, it draws inspiration from existing industry methodologies and unregistered pilot CDR approaches, blending the best practices and cutting-edge science to create a comprehensive framework.”
