The global shipping industry plays a crucial role in world trade, but its heavy reliance on fossil fuels poses challenges related to price volatility, geopolitical risks, and environmental concerns. Hanwha, a South Korean conglomerate, highlights the importance of transitioning to electrification in the maritime sector through energy storage systems (ESS) and hydrogen fuel cells. ESS provide battery storage for propulsion and auxiliary power, while hydrogen fuel cells generate electricity with water as the only byproduct. While fully electric ocean-crossing ships are a long-term goal, incremental adoption is seen in vessels like ferries and tugs. Challenges such as hydrogen storage and infrastructure availability persist, but ammonia is explored as a potential hydrogen carrier. Hanwha's investments in hydrogen technology and DNV's Approval in Principle for a 200kW hydrogen fuel cell system demonstrate progress in maritime electrification. Leveraging its expertise in energy, propulsion, and shipbuilding, Hanwha aims to enhance maritime energy security and sustainability.
