- Ship-Integrated Fuel Cell project reaches milestone thanks to close cooperation between ThyssenKrupp Marine Systems and sunfire
- Project targets reduction in fuel consumption and emissions
- Commissioning on land to occur before end of 2015; test operation at sea planned in 2016
Dresden–The delivery of an initial sunfire high-temperature solid oxide fuel cell (SOFC) to ThyssenKrupp Marine Systems represents the achievement of an important milestone for the Ship-Integrated Fuel Cell project (SchiBZ). ThyssenKrupp Marine Systems (as consortium leader) and sunfire have been working together on the e4ships beacon project – part of the National Innovation Programme for Hydrogen and Fuel Cell Technology (NIP) – since 2013.
The aim of the project is to demonstrate the reliability of fuel cells as an on-board source of day-to-day power for ships. The aim of using SOFCs on ocean-going vessels is to reduce both fuel consumption and emissions. Stricter legislation in the maritime sector is just one reason why this is necessary.
Having successfully tested the system at its headquarters in Dresden, sunfire has now supplied ThyssenKrupp Marine Systems with an initial SOFC with an electrical output of 50 KW. The electric output achieved by the prototype fuel cell can be raised to 500 kilowatts by increasing both its specific power and number of modules.
The newly developed SOFC module runs on low-sulphur diesel rather than hydrogen or natural gas. As a leading SOFC manufacturer sunfire is responsible for the delivery of SOFC technology to ThyssenKrupp Marine Systems. sunfire’s SOFC technology uses a ceramic solid electrolyte to convert fuel into electric power and heat at an operating temperature of around 800 degrees Celsius.MARINE SYSTEMS WITH 50 KW SOFC The recirculation of exhaust gases with the aid of a relatively simple, cost-efficient, integrated reforming process developed by the Aachen-based Öl-Wärme-Institut (OWI) makes it possible to achieve electrical efficiency of over 50 per cent and overall efficiency in excess of 90 per cent.
The prototype installed on the MS Forester (the test ship provided by Reederei Braren) will deliver between 25 and 50 per cent of on-board power. One objective targeted as part of the SchIBZ project is a significant reduction in fuel consumption on and harmful emissions from marine vessels. In particular it is to be ensured that stricter legislation governing the marine environment is complied with.
The results achieved within the framework of the SchiBZ project can be transferred to a variety of applications: In addition to naval vessels, special ships and cruise liners the SOFCs could also be used on land – for example as mobile power generators for the industrial sector.
