Carbon capture represents a beacon of hope in the realm of climate technology. If harnessed effectively, it holds the potential not only to arrest the course of climate change but also to reverse its effects by rectifying the damage already incurred. A key challenge, however, lies in the exorbitant costs associated with most carbon capture systems, coupled with their impractical scalability. Enter Captura, a spin-off from Cal-tech, which is poised to revolutionize the field with its ocean-based carbon capture innovation. This technology not only promises to be one of the most cost-effective solutions available but also boasts the capability to achieve an impressive gigatonne-per-year capacity. Unsurprisingly, both the Department of Energy (DOE) and visionary entrepreneur Elon Musk have extended substantial investments toward this game-changing initiative. But what exactly is the mechanism behind this technology, and can it genuinely combat climate change?

At the heart of Captura's approach lies the extraction of carbon dioxide from the ocean. At first glance, this might seem counterintuitive, given that atmospheric carbon dioxide is the primary driver of climate change. However, carbon dioxide exhibits solubility, leading the oceans to absorb substantial quantities of it. Astonishingly, nearly 30% of our annual emissions are absorbed by the oceans. Once absorbed, carbon dioxide transforms into bicarbonate, accompanied by a small proportion of carbonic acid. This seemingly complex chemistry has an unexpected advantage—these forms of carbon dioxide exhibit higher reactivity compared to their gaseous counterpart, which remains largely inert. This elevated reactivity opens avenues for innovative chemical processes that can be leveraged to remove and store carbon dioxide. Furthermore, water's density, being approximately 800 times greater than that of air, translates to oceanic carbon dioxide concentrations being 120 times higher than atmospheric concentrations by volume. This inherent density amplification augments the efficiency of any carbon capture technology, rendering ocean-based solutions even more potent.

So, why did Captura turn its attention to the oceans? The answer lies in their groundbreaking technology. The cornerstone of their approach is the electrochemical pH swing process, which is notably more straightforward than its name suggests. Essentially, this process involves manipulating ocean water to become more acidic. The journey commences with Captura extracting ocean water and channeling it into their specialized device. Within this apparatus, a small fraction (1%) of the sample undergoes treatment via a bipolar membrane. This membrane, in essence, facilitates the efficient separation of molecules.

In essence, Captura's innovative approach tackles carbon capture by tapping into the oceans' potential. Their technology, powered by electrochemical pH swing, harnesses the oceans' natural properties to facilitate the removal and storage of carbon dioxide. With its ingenious design and the utilization of oceanic resources, Captura's endeavor presents a beacon of hope in the fight against climate change. As humanity grapples with the imperative of curbing carbon emissions, solutions like Captura's hold the promise of creating a more sustainable and harmonious future.
