Singapore Advances With Dual-Technology Project to Combat Climate Change and Generate Hydrogen

Surprising And Innovative Installation Removes CO2 From Seawater, Increasing Carbon Absorption By Oceans And Producing Hydrogen And Calcium Carbonate

An innovative initiative in Singapore is marking a significant advancement in the fight against climate change and the search for clean energy sources. Local scientists are planning to expand a pilot project that not only increases the oceans’ capacity to absorb carbon dioxide emissions but also generates hydrogen and a vital component for the construction industry, according to the website One Planet.

CO2 Removal Technology From Oceans (OCDR) And Hydrogen Production

Technologies for the removal of carbon dioxide from the oceans, known as OCDR, have been studied by scientists worldwide for some time, but significant results have been elusive. However, the Public Utilities Board of Singapore has taken a step forward by creating a plant that uses electricity to extract CO2 from seawater. The “clean” water, now without CO2, is then pumped back into the ocean, allowing it to absorb more carbon dioxide. 

Located at a desalination facility on the west coast of the city-state, this initiative already extracts 100 kilograms of CO2 per day, using technology developed by the American company Equatic, founded by scientists from the University of California, Los Angeles (UCLA). After the CO2 is removed, the seawater passes through an electrolyzer, which converts the captured carbon into calcium carbonate and generates hydrogen as a byproduct.

Expansion Prospects And Commercial Potential

The Public Utilities Board of Singapore is now seeking funding to build a plant with a daily capacity of 10 tons, demonstrating its commitment to expanding this innovative technology that can also generate hydrogen. Gurdev Singh, the project leader, stated: “We have shown that the technology works, but the key now is to optimize it for large-scale use.” 

This initiative is considered crucial in light of the recommendations from the Intergovernmental Panel on Climate Change (IPCC), which emphasizes that the removal of CO2 from the atmosphere will be as important as reducing emissions to combat global warming. Although OCDR techniques have been praised as unsung heroes in the fight against climate change, it remains unclear whether these new technologies are viable on a large scale.

Commercial Potential And Sustainable Impact For Hydrogen Production

The founder of Equatic, Gaurav Sant, highlighted the commercial potential of this multifaceted technology. He pointed out: “What makes this commercial opportunity resilient is that you can essentially have the same equipment to provide two products: carbon credits and hydrogen.” Additionally, there is the possibility of profit through the sale of calcium carbonate to the construction industry, where it is used in cement manufacturing, among other applications.
This innovative project is one of several OCDR pilot ventures worldwide. Some of these initiatives rely on techniques such as bringing nutrient-rich deep waters to the surface to stimulate seaweed growth, while others aim to reduce ocean acidification levels, which would also increase their absorption capacity.
