DeepGreen announces business combination agreement with the Sustainable Opportunities Acquisition Corporation (SOAC) to become The Metals Company
Providing the capital required to get through a feasibility study and into potential revenue as early as 2024—when many analysts anticipate nickel and copper shortages from current sources—and representing a pro forma equity value of $2.9 billion for the combined company, the business combination included $330 million in private investment in public equity, or PIPE, at $10 (USD) a share. The strategic and institutional investors forming this international consortium include Allseas, Maersk Supply Service, and Glencore, among others.

Bjarke Ingels Group (BIG) and The Metals Company announce collaboration to design a new generation of offshore and onshore assets to produce critical electric vehicle battery metals from polymetallic nodules
The Metals Company challenged the architect Bjarke Ingels and his internationally renowned firm, BIG—well known for creating a ski slope on a waste-to-energy plant in Copenhagen—to bring innovative, whole-systems design to the industrial components needed to supply metals from polymetallic nodules, remaking conventional metal production for the 21st century. In addition to a first-generation collector vehicle, BIG is designing other radical, low-impact solutions: a surface production vessel, a 216-meter-long ship that runs on carbon-neutral electrofuels, with a sunken deck covered with photovoltaic solar panels; shuttle carriers, whose X-bow design will deliver hyper-efficient, hydrodynamic ships; and a portside processing plant, built to become a performative and social campus in a regenerative landscape.

First comprehensive study on lifecycle ESG impacts of metal production from nodules versus land ores published
Lead researchers Daina Paulikas (University of Delaware) and Dr. Steven Katona (Ocean Health Index, Conservation International) found that sourcing battery metals from polymetallic nodules, rather than from terrestrial mines, would significantly reduce impacts with regard to climate change, nonliving resources, biodiversity and biomass, and measures of social and economic wellbeing.

Part of The Metals Company’s environmental and social impact assessment (ESIA), the company’s research program includes dozens of discrete studies. The data collected will enable informed decision making and regulatory development. The multi-year integrated program will characterize the marine environment and species from the seafloor of the abyssal plain up through the water column to the surface of the ocean, studying everything from microbes to whales. All output and data generated will be shared with the international community and samples collected are sent to labs around the world for analysis. This collaborative effort will advance the wider fields of ocean science, medicine, and technology.
First peer-reviewed study on lifecycle climate change impacts of metal production from nodules vs land ores published
Providing a comparative life-cycle assessment of electric-vehicle battery metal sources, this research paper quantifies the direct and indirect emissions and disruptions to carbon sequestration by the mining, processing, and refining of battery metals. Researchers Daina Paulikas (University of Delaware), Dr. Steven Katona (Ocean Health Index, Conservation International), Erika Ilves (The Metals Company), and Saleem H. Ali (University of Delaware) found that producing battery metals from nodules can reduce active human emissions of CO2 by 70-75%, stored carbon at risk by 94%, and disruption of carbon sequestration by 88%. Their analysis also found that polymetallic nodules can deliver metals for one billion EV batteries with up to 11.6 gigatons less CO2.

ISA grants polymetallic nodule exploration contracts to NORI, sponsored by the government of Nauru, and to TOML, sponsored by the Kingdom of Tonga
Speech by Nii Allotey Odunton, ISA Secretary General, to U.N. General Assembly on the occasion of the first exploration contracts granted to private companies sponsored by developing states
“The only realistic option for most developing states… is to form partnerships with commercial interests that have access to the financial capital and technology that are necessary to conduct deep-sea exploration. This is exactly what has happened in the case of Nauru and Tonga. This could not have happened, however, unless the private sector had sufficient confidence in the regulatory system that has been developed by the [ISA] over the past fifteen years to make such an investment in the first place.” —Nii Allotey Odunton, ISA Secretary General
ITLOS Seabed Disputes Chamber (SDC) Hearing on Responsibilities and Obligations of Sponsoring States takes place
United Nations Convention on the Law of the Sea (UNCLOS) 1994 Implementation Agreement signed and the ISA is established.
The UNCLOS ensures that the development of seabed mineral resources beyond national jurisdiction will benefit developing states, and not just wealthy countries, and reaffirms the seafloor as “the common heritage of mankind.” This document officially formed the ISA, an autonomous international organization headquartered in Kingston, Jamaica, with the mandate to ensure the effective protection of the marine environment from harmful effects that may arise from deep-seafloor related activities. As of 2020, the ISA has 168 member states and the European Union.
Oceanographer and environmentalist Jacques Cousteau uses a delay in the signing of the draft treaty at the U.N.’s Law of the Sea conference to rework the regulatory framework that exists today and to educate the public
“What we are trying to do, but we have very little hope to change through governments, is to use the delay in signing the treaty to slightly modify the concept of exclusive economic zones into zones of responsibility. But in order to do that we would have to create a world ocean authority. Not only for the open ocean, but also for the continental shelves. This world ocean authority could set global rules of management of the ocean accepted by every nation. And then every coastal nation would be responsible to implement these rules in the so-called economic zones. That’s a dream that we’re trying.” —Jacques Cousteau
Cousteau also advocates for the development of polymetallic nodules as a resource.
“I see nothing wrong about dredging nodules from the bottom of the ocean. But it is not economical at the moment. It is only justified for strategic reasons in the US and in France and Japan — three countries that have already invested a lot in this field — because they understand that some of the minerals are in short supply.” —Jacques Cousteau
Various multinational companies and publicly sponsored groups take significant interest in the potential uses of polymetallic nodules.
Investing heavily in finding deposits and in mining and processing research and development, two groups collect several hundred tons of polymetallic nodules from the abyssal plain of the eastern equatorial Pacific and extract nickel, copper, and cobalt. The missions result in a number of technological developments for deep-sea exploration, but due to land-based nickel supplies, the cost of commercialization and no regulatory framework, no large-scale nodule collection continues.
The H.M.S. Challenger expedition takes place, funded by the Royal Society of London. This scientific program led to the foundation of oceanography and a number of important discoveries, and recovered hundreds of manganese nodules from the Pacific, Indian, and Atlantic Oceans.
