In a bid to make maritime transport more sustainable, researchers have been exploring various carbon capture technologies, but a new study suggests that safety should be a bigger part of the conversation. Published in the journal *Chemical Engineering Transactions* (or, in English, *Transactions of Chemical Engineering*), the research led by Francesco Zanobetti integrates inherent safety into a broader sustainability framework to evaluate carbon capture options for hard-to-abate sectors, including maritime transport.
The study looked at three carbon capture technologies: solvent-based absorption (like amine scrubbing), adsorption, and cryogenic separation. The findings revealed that amine scrubbing, a commonly used method, poses significantly higher safety risks compared to the other options. “Amine scrubbing demonstrated a hazard level at least 15 times higher than alternative capture technologies,” Zanobetti and his team found. This highlights the need to consider safety alongside environmental and economic factors when selecting carbon capture technologies.
For the maritime sector, this research could have significant implications. Cruise ships and other vessels are increasingly looking for ways to reduce their carbon footprint, and carbon capture is one avenue being explored. However, the safety of the crew and passengers is paramount. The study’s findings suggest that not all carbon capture technologies are created equal when it comes to safety, and trade-offs may need to be made between safety and environmental performance.
From a commercial perspective, this research could open up opportunities for companies developing safer carbon capture technologies. As the maritime industry seeks to decarbonize, there will be a growing demand for technologies that can effectively capture CO2 without compromising safety. This could drive innovation and investment in safer carbon capture solutions, creating new business opportunities.
Moreover, the study’s emphasis on inherent safety could influence regulatory standards and industry practices. As awareness of the safety risks associated with certain carbon capture technologies grows, there may be a shift towards safer alternatives. This could lead to changes in industry standards and regulations, further driving the demand for safer technologies.
In essence, this research serves as a reminder that sustainability is not just about reducing emissions; it’s also about ensuring the safety of those involved in the process. As the maritime industry continues to explore carbon capture as a means of decarbonization, it will be crucial to consider all aspects of sustainability, including inherent safety. After all, a sustainable future is not just about protecting the environment; it’s also about protecting people.
