Climate tech company, Calcarea, and naval architecture and marine engineering firm, Aurelia Design, have entered into a collaboration to bring ocean-based carbon capture technology to the maritime sector. The partnership combines Calcarea’s carbon removal process with Aurelia’s expertise in green ship design and e-systems integration, Aurelia said in a statement today (10 November). Central to the collaboration is Calcarea’s limestone weathering technology — a system that, noted Aurelia, accelerates a natural process where carbon dioxide (CO₂) reacts with limestone and seawater, transforming it into stable bicarbonates safely stored in the ocean. According to Aurelia, the approach ‘offers a nature-based, permanent, […]

ClassNK’s newly-published second edition of its Guidelines for Onboard CO2 Capture and Storage Systems now includes ‘world-first’ requirements for onboard CO2 capture systems (OCCS) using the membrane separation method. In the first edition of the guidelines, published in 2023, ClassNK outlined requirements for OCCS using amine absorption method. In a statement issued today (29 October), ClassNK said that expanding the guidelines to include the membrane separation method was important because it has a ‘lower energy requirement compared to amine absorption method and does not require a permanent supply of amine solution’. The guidelines are available to download here via ClassNK’s […]

Spanish bulk liquids logistics company Exolum is planning the construction of a terminal at the outer port of A Coruña which would be able to store and blend conventional products and sustainable fuels, such as renewable ammonia, captured CO₂, green methanol, sustainable aviation fuel, and other biofuels. The project, which is said to be in the early stages of planning, would be developed on a phased basis and could reach a capacity of over 160,000 cubic metres across two separate but connected sites. The facility would feature 22 tanks, and the proposal will include a railway loading bay, loading islands […]
