BEHOLD... The Unleashing of H2OAquatics: Here's OUR way of Carbon Capture in the Depths of the Ocean

Electrochemical Systems

The method described for removing carbon dioxide from ocean water involves using an electrochemical system with bismuth and silver electrodes that can capture and release chloride ions. The difference in reaction stoichiometry between the two electrodes enables an electrochemical system architecture for a chloride-mediated electrochemical pH swing, which can be leveraged to remove CO2 from ocean water without costly bipolar membranes effectively.

Operating BismuthSystems

We utilize two silver-bismuth systems operating in tandem in a cyclic process. One system would acidify the ocean water, and the other would regenerate the electrodes through the alkalization of the treated stream. This would allow for CO2 to be continuously removed from simulated ocean water with a relatively low energy consumption of 122 kJ mol−1, and high electron efficiency. Ensuring effective remocal of carbon.

AUV and ROV Integration

The design includes a system for deploying and controlling the electrochemical system in the ocean. This could involve autonomous underwater vehicles (AUVs) or remotely operated vehicles (ROVs) to transport and operate the electrochemical system. The AUV or ROV is equipped with an electrochemical system and the necessary sensors and control systems to monitor and adjust the operation of the system.

A technology-first approach to save our oceans

With a technological soltuion and a plan of action, anything is possible.

Fast & secure movement

The first step in the process would be to design an autonomous underwater vehicle (AUV) or remotely operated vehicle (ROV) that is capable of carrying the electrochemical system to the target location. This would require an underwater robot able to move through the water and navigate to a specific location.

Target Location and Deployment

Once the robot arrives at the target location, it would need to deploy the electrochemical system into the ocean. This could involve the use of robotic arms or other mechanisms to position the electrodes in the water. The robot would also need to ensure that the electrochemical system is secured in place to prevent it from drifting.

Initiating Carbon Capture

Once the electrochemical system is in place, the robot would need to initiate the carbon capture process. This involves the cyclic process of acidifying and alkalizing the ocean water using the two silver-bismuth systems. Operation checks would begin, checking on the acidification and alkalization functions.

Processing

The robot would also need to monitor the concentration of CO2 in the water to determine when the electrochemical system has captured enough CO2. This would require sensors capable of measuring the CO2 concentration in the water. Once the desired amount of CO2 has been captured, it would be transported back to the surface for processing.

Why H2OAQUATICS makes sense!

The traditional methods of addressing ocean acidification, such as reducing carbon emissions and promoting the growth of seaweed forests, have proven to be insufficient in curbing the effects of ocean acidification. Thus, highlighting the need for change.

According to the National Oceanic and Atmospheric Administration (NOAA), ocean acidification is happening at a rate faster than any time in the past 300 million years. The current rate of ocean acidification is causing serious harm to marine life and ecosystems, with shell-forming organisms such as oysters and clams being particularly vulnerable.

The proposed electrochemical system can remove CO2 from seawater with relatively low energy consumption and high electron efficiency. The system requires only 122 kJ mol−1, which is significantly lower than other carbon capture and storage technologies. This means that the proposed system could be more cost-effective than other methods of addressing ocean.

The proposed electrochemical system has the potential to remove CO2 from ocean water continuously, unlike other methods that may be limited by factors such as weather conditions and the availability of suitable locations for seaweed forests or carbon storage facilities.

The proposed electrochemical system can be scaled up to suit different levels of carbon capture needs, from small-scale applications to large industrial installations. In the near future, this scalability gives us the heads up, that our solution IS THE ANSWER.

In terms of specific numbers, the proposed system's energy efficiency of 122 kJ mol−1 compares favorably to other carbon capture technologies that typically require 250-350 kJ mol−1. Additionally, the system's scalability makes it a versatile solution for addressing ocean acidification on a wide scale.

Once the robot arrives at the target location, it must deploy the electrochemical system into the ocean. This could involve the use of robotic arms or other mechanisms to position the electrodes in the water.
