Ocean Alkalinity Enhancement Engineering Award (OAE) is Now Open for Pre-Proposals

May 24, 2022

We invite pre-proposals to develop prototypes that could enable safe, cost-efficient, and scalable OAE as a potential method for large-scale carbon dioxide removal (CDR). These prototypes may include, but are not limited to:

  • Mechanisms to efficiently prepare and/or disperse alkaline substances into seawater (e.g., mechanical hardware, chemical processes, etc.).
  • Designs, technologies, and supporting software to integrate OAE deployment and MRV into existing marine and coastal industries, such as transoceanic shipping, desalination, offshore wind, and commercial fishing.
  • Sensors and platforms to support monitoring, reporting, and verification (MRV) of OAE.


Teams may apply for grants of $750k – 1.5M to fund projects of up to 18 months.

Pre-proposals are due by August 5, 2022.
