Core Viewpoint - Deep-sea mining is transitioning from exploration to development, driven by technological advancements and increasing demand for deep-sea metals, although it still faces significant economic, environmental, and legal challenges [1][2]. Industry Overview - The deep sea contains over 60 types of metals, including copper, cobalt, nickel, and gold, with an estimated resource volume of approximately 30 billion tons and a recoverable potential of about 7.5 billion tons [2]. - The price surge of various metals, particularly copper and cobalt, has made deep-sea mining economically viable [2]. - Historical attempts at deep-sea mining date back to the late 19th century, with significant efforts in the 1970s, but commercial viability remains elusive [2]. Environmental Concerns - There are ongoing debates regarding the environmental impact of deep-sea mining, with 37 countries advocating for a pause or ban until comprehensive environmental assessments are conducted [3][4]. - Key environmental concerns include sediment plumes, heavy metal pollution, and noise pollution affecting marine life [5][6]. Legal Framework - The current legal framework for deep-sea mining is primarily governed by the United Nations Convention on the Law of the Sea, which outlines the management and regulation of international seabed activities [7]. Commercialization Challenges - Despite technological advancements in mining equipment, such as mining vehicles and ships, profitability models remain unproven, with significant operational challenges including equipment malfunction and low extraction efficiency [9]. - The extraction process from depths of 4,000 to 6,000 meters presents logistical challenges, with no existing pipelines capable of such depths [9]. - The complexity of deep-sea equipment development and the high costs associated with testing further complicate commercialization efforts [9][10]. Alternative Applications - The technology developed for deep-sea mining vehicles may find alternative applications in offshore wind turbine maintenance, leveraging expertise in marine soil mechanics [11].

Core Viewpoint - Deep-sea mining is transitioning from exploration to development, driven by technological advancements and increasing demand for deep-sea metals, but it still faces significant cost, environmental, and legal challenges before commercialization can be achieved [2][4]. Group 1: Industry Overview - The deep sea contains rich metal resources, including over 60 types such as copper, cobalt, nickel, and gold, with an estimated total resource volume of approximately 30 trillion tons and a recoverable potential of about 750 billion tons [4]. - The prices of various metals have surged in recent years, making deep-sea mining economically viable, particularly for metals like copper and cobalt [4]. - Historical attempts at deep-sea mining date back to the late 19th century, with significant efforts in the 1960s and 1970s, but these were largely abandoned due to a lack of understanding of the minerals' uses [4]. Group 2: Environmental and Legal Concerns - There is ongoing controversy regarding the environmental impact of deep-sea mining, with 37 countries advocating for a pause or ban until the effects are fully understood and regulations are established [5][6]. - Key environmental concerns include sediment plumes (referred to as "feather flow"), heavy metal pollution, and noise pollution affecting marine life [7][8]. - Legal issues arise from the international nature of deep-sea resources, governed by frameworks such as the United Nations Convention on the Law of the Sea, which outlines resource management and distribution [8]. Group 3: Commercialization Challenges - Despite technological advancements in deep-sea mining equipment, such as mining vehicles and ships, a viable revenue model has not yet been established [11]. - Current mining vehicles face significant operational challenges, including slippage, sinking, and low extraction efficiency, with the best-performing vehicle extracting only about 100 tons of polymetallic nodules per hour [11][12]. - The complexity of deep-sea equipment development and the high costs associated with testing limit the pace of commercialization [12][13]. Group 4: Alternative Applications and Collaborations - While deep-sea mining vehicles have not yet been commercialized, they have potential applications in offshore wind turbine maintenance, leveraging research in marine geotechnics [14]. - Collaboration between heavy equipment manufacturers and deep-sea mining researchers is encouraged to combine manufacturing strengths with marine expertise, positioning companies advantageously in the deep-sea technology sector [14].
