Innovative Carbon Capture Technology Aims to Reduce Shipping Emissions

According to Positive News, global shipping is responsible for about 3% of greenhouse gas emissions, making it a significant contributor to climate change. The London-based startup Seabound has introduced an innovative solution that leverages quicklime, a form of calcium oxide, to capture carbon emissions from cargo ships.

Their carbon capture technology works by funneling exhaust fumes through quicklime pebbles, which absorb carbon dioxide and convert it into harmless limestone. This process not only eliminates carbon emissions but also captures up to 90% of toxic sulfur exhaust fumes.

During a three-week trial, Seabound's system successfully removed 78% of a ship's carbon emissions, demonstrating its potential to significantly reduce the shipping industry's carbon footprint. The compact design of the technology allows it to fit into a standard shipping container, facilitating easy installation and replacement on cargo decks in port.

However, there are challenges ahead, particularly concerning the sustainable production of quicklime, which can be energy-intensive and carbon-heavy if sourced conventionally. Critics of carbon capture technology argue that it may distract from the urgent need to transition away from fossil fuels, though some experts recognize its necessity in achieving climate targets.

This technology comes at a critical time as the shipping sector faces mounting pressure to reduce emissions, particularly following setbacks in international agreements to tackle this issue. In addition to Seabound's efforts, other innovative approaches are emerging in the maritime industry.

British marine engineers at BAR Technologies are testing modernized sails that resemble wind turbine blades to harness wind energy effectively for cargo vessels. Moreover, the launch of the world's largest electric ferry, which can carry over 2,000 passengers and is set to operate between Argentina and Uruguay, showcases the potential for electric solutions in maritime transport.

Overall, Seabound's advancements in carbon capture technology represent a promising step towards a more sustainable shipping industry, contributing positively to global efforts aimed at reducing greenhouse gas emissions.
