In the vast expanse of the world’s oceans, cargo ships traverse countless miles, transporting goods that fuel our global economy. Yet, these maritime workhorses are also significant contributors to global carbon dioxide emissions, a stark reality that scientists and engineers are now determined to tackle. A recent study published in Frontiers in Marine Science, a leading journal, explores a novel approach to mitigating these emissions using a Calcium Hydroxide (Ca(OH)2) based Carbon Capture System (CCS), offering a glimmer of hope for both the maritime industry and the planet.
Valentina Bortuzzo, a researcher from the Department of Engineering and Architecture at the University of Trieste, Italy, leads the charge in this innovative study. She and her team are exploring the potential of CCS to reduce CO2 emissions from cargo ships, a sector that has long been challenged by the persistence of these greenhouse gases.
“We’ve made significant strides in reducing other pollutants like Nitrogen Oxides (NOX) and Sulfur Oxides (SOX), but CO2 remains a formidable challenge,” Bortuzzo explains. “Our study delves into the untapped potential of CCS onboard ships, not just for emissions reduction, but also for addressing ocean acidification and promoting a circular economy.”
The proposed system uses Calcium Hydroxide to capture CO2, converting it into Calcium Carbonate (CaCO3), a compound that can be reused in various industries. This dual benefit—reducing emissions and creating a valuable byproduct—marks a significant leap forward in the fight against climate change.
The commercial implications for the energy sector are profound. As the world increasingly demands sustainable practices, the maritime industry is under pressure to reduce its carbon footprint. The integration of CCS onboard ships could not only help meet these demands but also open new avenues for revenue through the sale of captured CO2 or its byproducts.
The study also highlights the logistical and spatial challenges of implementing CCS on ships, but Bortuzzo remains optimistic. “While the hurdles are considerable, the potential benefits are even greater,” she says. “We’re at a critical juncture where innovation and bold thinking are essential to safeguard our marine environment and combat climate change.”
As the world continues to grapple with the realities of climate change, research like this offers a beacon of hope. It underscores the urgent need for transformative measures in the maritime sector, paving the way for a future where cargo ships not only transport goods but also play a pivotal role in protecting our planet. The study, published in the journal ‘Frontiers in Marine Science’ (a journal of marine science) provides a pathway to a greener, more sustainable future for the maritime industry and the energy sector at large.
