Green Fuels in Maritime Shipping

Green Fuels in Maritime Shipping

Heating, electric power supply and ship propulsion with hydrogen and LNG fuels
Carsten Fichter, Uwe Werner
In current times, heavier fuels such as oil and diesel are generally used to power merchant and passenger ships alike. International and national regulations are likely to increase pressure to reduce greenhouse gas emissions of sulfur and nitrogen oxide, carbon dioxide, and fine dust pollution within the global maritime shipping industry. Green fuels are one possible solution for emission reduction. Therefore, the International Maritime Organization (IMO) create the International Convention for the Prevention of Pollution from Ships (MARPOL), Annex VI of which enables the enforcement of designated (sulfur) emission control areas (ECAs or SECAs). Current research shows that hydrogen and LNG fuels can be safely operated and used to supply electric generating systems and drive systems. Today, cruise ships are often constructed with LNG main propulsion engines. Conventional hydrogen and LNG fuels are not CO2 free. However, green hydrogen, green ammonia and green LNG are based on ...

Electrical and Hydrogen Microgrid

Electrical and Hydrogen Microgrid

Energy Control of a Self-Sufficient Supply System Based on a Combined Electrical and Hydrogen Distribution Grid
David Salomon Stephan, Uwe Werner, Carsten Fichter
The main goal of assembling a self-sufficient microgrid is to integrate all technical equipment into an autonomous energy supply system as a virtual power plant (VPP). The system integration focuses on the power electronic devices and the combination of gas and electrical supply chains. The developed microgrid structure is fed from renewable energy systems (green hydrogen), the electrical grid and the H2 gas grid with a liquid or gaseous energy source. In comparison to an island grid, the microgrid can be operated in parallel mode with the common public grid. The associated challenges of transient energy flows and the holistic view of a regulated microgrid based on an electrical grid and an H2 gas network are part of this article.
