Project Summary / Description:

SeaWell and related SeaHawk were formed in 2018; ZONDDAC was formed in 2020. 

Project advances technology readiness of test ZDAC Aerodynamic Sorbent Emitter (ASE), designed for low-cost atmospheric carbon removal and ocean alkalinity enhancement (OAE). The technology integrates desalination and brine-to-chlor-alkali process for sodium hydroxide (NaOH) production onboard an offshore floating turbine platform (SeaHawk), where sorbent is produced and emitted through a novel, high-volume, fine particle emitter at turbine nacelle height.

The Project is organized as a high-urgency mission to launch ZDAC carbon removal technology with prototype SeaHawk-ZDAC testing in 2024, and the first commercial project targeted for mid-decade, positioning the technology for adoption across the rapidly expanding offshore wind turbine sector.

Atmospheric carbon dioxide (CO2) removal with OAE, powered by offshore wind energy, presents a uniquely efficient approach to attaining gigaton-scale atmospheric carbon removal by mid 2030‚ .

How Project Affects Greenhouse Gas (GHG) Emissions:

Replaces/avoids GHGs (e.g., projects that replace sources of GHGs, such as the burning of fossil fuels for electricity, heat, transport, or other energy uses), Reduces GHGs (e.g., projects that reduce sources of GHGs, such as through efficiency or other changes in consumption), Removes/stores GHGs (e.g., projects that capture, sequester, or otherwise enhance the "sinks" that accumulate and store GHGs)

Impact on Underrepresented Groups:

Internal Diversity Reaching Outward ‚ Dehlsen Associates ( DA ) and Ecomerit Technologies ( Ecomerit ) have a mixed gender, multicultural team with members residing in New Zealand, the United States, Mexico, and the United Kingdom, working towards energy transition and sustainability imperative that benefits the global underrepresented population, particularly women and the impoverished. It starts internally, where Team members bring differing sets of experiences, ideas, and philosophies, and their own unique perspective toward social justice.

Equity ‚ The overriding social equity factor is helping abate species extinction, including human, by carbon removal to mitigate temperature rise and the societal burden that it imposes. The SeaHawk platform‚ bulk freshwater supply can be brought to water-scarce, underserved regions globally, driven by clean electric power generated at the source (e.g., wind power), substantially reducing energy cost and losses, thereby, able to reach more underserved population. First deployment locations are planned to be near otherwise ignored and disadvantaged communities when it comes to water and climate change impacts.

Inclusion ‚ Management believes in the importance of fostering fairness and respect, establishing upfront on how we communicate as a team in a way that promotes equity within the team. We will also seek to hire local members of disadvantaged communities and/or create jobs within those communities to construct, deploy, maintain, upgrade, intervene, decommission projects we develop. Our general policy is to create an inclusive environment where team members feel empowered to share ideas, issues, and concerns, regardless of their background, an approach fundamental to reaching a wider population.

Mission Statement:

Ecomerit Technologies ( Ecomerit ) was formed by Jim and Brent (son) Dehlsen in 2008. Jim is the inventor of the ZONDDAC System ( ZDAC ) for the removal of atmospheric carbon dioxide. Jim has over three decades of creating and leading businesses based on innovation and development of renewable-energy technologies, including wind turbines, ocean current turbines, and utility scale wave energy power systems, along with technologies for ocean-based energy applications. Jim has been awarded 33 distinct patents. The track record for innovation and technology delivery of the Ecomerit Group has earned the support from the U.S. Department of Energy (DOE), Bureau of Ocean Management (BOEM), U.S. Navy, the State of Florida, and the UK Government. Ecomerit has offices in Matakana, New Zealand, Santa Barbara, California, and London, the United Kingdom.
