Provaris Energy gets DNV approval for large-scale liquid CO2 tank design, advancing marine carbon transport

Provaris Energy has received approval in principle from DNV for its large-scale liquid CO2 tank design, a key step toward building ships that can transport captured carbon dioxide. The approval covers the tank's structural integrity, safety systems, and compliance with maritime regulations. This milestone moves the company closer to offering a complete marine transport solution for carbon capture and storage projects. Marine transport of CO2 is a missing link in many CCS value chains. Without ships that can carry large volumes of liquid CO2 safely, onshore storage sites remain disconnected from emission sources. Provaris is working on both the tank design and the vessel integration, aiming to have a fully certified system ready for commercial deployment. The DNV approval signals that the design meets the technical requirements for class certification. For carbon markets and climate finance, this matters because scalable CO2 transport infrastructure directly affects project viability. If Provaris can deliver a certified tank and ship package, it could unlock storage projects that currently lack a cost-effective way to move CO2 from capture points to injection sites.
