Oliver Gunasekara Asks: Can Deep Sea Mining Save the Planet?
A Wake-Up Call for the Climate Crisis
I’m John Paul Flores, host of The New World Podcast, and I’ve heard my share of bold claims about solving the climate crisis, but when I first came across deep sea mining, I wasn’t sure if it was just another controversial idea or something worth seriously considering. The concept seemed far-fetched, too extreme. But my conversation with Oliver Gunasekara, founder of Impossible Metals, opened my eyes to something I hadn’t anticipated.
Oliver’s journey wasn’t a direct path to deep sea mining. After years of leading global tech companies like Arm, he thought he was ready to slow down. That was until the devastating wildfires in the Bay Area jolted him awake. He realized that in the face of the climate crisis, he had to act. And that’s when he shifted his focus toward finding sustainable solutions to our world’s growing resource needs, eventually leading him to deep sea mining.
The Promise and Potential of the Ocean
At first, I was skeptical. After all, mining the ocean floor sounded like a step backwards, a repeat of the destructive practices we see on land. But Oliver wasn’t talking about conventional mining methods. He was talking about a completely new approach.
“The future is electrification, renewables, nuclear... but it needs massive innovation across the stack," Oliver shared with me. He wasn’t just referring to the software world he had once known. He meant the need for actual hardware—metals that power electric vehicles, batteries, and renewable energy sources. And these metals, like nickel and cobalt, are crucial for the electrification of our future. But how do we get them without decimating the environment?
That’s where Impossible Metals comes in. Instead of using destructive mining techniques, they’ve developed cutting-edge technology that uses autonomous robots and AI to selectively harvest polymetallic nodules from the ocean floor, making it possible to tap into these resources while avoiding unnecessary damage to marine life.
A Trillion-Dollar Opportunity Beneath the Waves
Here’s where things get even more interesting. The ocean holds an estimated $100 trillion worth of metals—enough to electrify all forms of transportation for the next century. I couldn’t help but think about the vast potential of these resources, but I also had to consider the risks. Could we mine the ocean without causing even more harm than we’ve done on land?
Oliver’s answer was clear: yes, but only with the right technology. "The ocean has so much potential, but it’s about using the right technology," he emphasized. Impossible Metals isn’t just about taking what’s beneath the surface; it’s about doing it in a way that protects the delicate ecosystems of the deep ocean.
The Environmental Dilemma: Can We Do This Responsibly?
As we dug deeper into the conversation, I began to understand that the fear around deep sea mining isn't just about the unknown depths—it’s about the consequences of doing it wrong. Some critics argue that mining the deep sea could be just as destructive as the mining practices that have already ruined land-based ecosystems. And they’re not entirely wrong to be concerned.
However, Oliver’s approach is different. “If we don’t do it, we’re just going to continue to rely on land-based mining—where the impacts are far worse,” he said. Illegal mining operations, child labor, forced labor, and the destruction of biodiversity on land are ongoing issues that can’t be ignored. By turning to the ocean, we could minimize the damage caused by land-based mining, but it must be done responsibly, with careful planning and execution.
The Technology Behind Impossible Metals
Here’s where things get truly fascinating. Oliver isn’t relying on traditional mining methods that indiscriminately ravage the environment. Instead, Impossible Metals uses AI and autonomous robots to perform selective harvesting. These robots, which hover over the ocean floor, use computer vision to identify and avoid marine life while collecting polymetallic nodules—a process that minimizes disruption to the surrounding habitat.
The commitment to sustainability is impressive. “We want to preserve 30% of the seabed untouched,” Oliver explained. This isn’t just about extracting as much as possible; it’s about balancing progress with preservation.
A New Path Forward
As our discussion continued, it became clear to me that this wasn’t just about mining—it was about creating a future where technology and environmental responsibility can coexist. Oliver’s vision is ambitious, but it’s also deeply pragmatic. He doesn’t believe that we can afford to leave deep sea mining behind, but he’s also committed to ensuring that it’s done right.
"We have to approach this with caution, with care, and with the right tools,” he said. The potential of deep sea mining is undeniable, but so is the responsibility to ensure that we don’t repeat the same mistakes that have plagued land-based mining for centuries.
The Choice Is Ours
As I reflect on everything I learned from Oliver, one thing stands out: the future of resource extraction isn’t about picking sides between the environment and progress. It’s about finding solutions that protect both. The technology exists, and with leaders like Oliver Gunasekara pushing boundaries, deep sea mining could be a part of a larger, more sustainable future.
However, as with all innovations, the road ahead isn’t without its challenges. We can’t afford to take the easy way out. We need to think carefully about the technologies we use, the impact we have on the environment, and the choices we make today. Oliver’s vision has shown me that it’s possible to change the future—we just have to be brave enough to take the right steps.
