The world's move towards cleaner energy sources has put green ammonia in the spotlight as a crucial element in this transition. This shift is driven by global commitments to reduce greenhouse gas emissions and the growing need for sustainable energy solutions. Ammonia, which consists of hydrogen and nitrogen, has emerged as a promising option for storing and transporting hydrogen, especially in its green and blue forms. It offers a safer and more cost-effective alternative to liquid hydrogen, overcoming challenges such as high energy requirements for liquefaction and safety concerns due to flammability. The maritime industry, well-versed in transporting liquefied gases, is gearing up to handle green and blue ammonia, leveraging existing safety protocols and infrastructure. Advances in ammonia carrier design, like increased cargo capacity and efficiency improvements, are enhancing the viability of ammonia transport on a larger scale. However, realizing this potential requires evaluating new technologies, addressing regulatory gaps, and integrating ammonia as a fuel with the necessary safety measures. Bureau Veritas Marine & Offshore is actively involved in supporting this transition by developing classification rules, conducting risk assessments, and ensuring safety and sustainability standards.
