A multinational shipping enterprise with a registered base in Scotland (UK) is seeking novel, cost-effective approaches to recover energy from the exhaust gases of ship engines and to transform it into more useful energy such as electricity to supply hotel loads on board the ship. The Scottish company is looking for partnerships via a commercial agreement with technical assistance or a technical cooperation agreement. The company is especially interested in technologies that are near to market.
A leading multinational shipping enterprise with a registered base in Scotland (UK) is looking for technology solutions that can be applied to their cargo and passenger ships that travel in all of the world's oceans. The company is actively involved with open innovation and is currently involved with several international projects.
Combustion engines onboard ships typically have an efficiency of 50% or less. As an example if a ship consumes 10000 tonnes of fuel in one year, less then 5000 tonnes is transformed into ”usable” energy. About 30% of the total energy available is lost through the exhaust gases. In the ideal case, the company would like to convert a significant portion of this waste heat and/or kinetic energy of the exhaust gases directly into electricity in a cost effective manner.
The client is looking to partner with companies that have a solution or a potential solution that is near to market and is therefore looking for partnerships via a commercial agreement with technical assistance or a technical cooperation agreement. The company is willing to consider technology from other end-application sectors that is capable of addressing the problem set out here. The client is flexible in the approach to required development. Some budget may be made available for development and this could include being actively involved in the development of a solution, technical overview of the end application and provision of testing facilities.
The company is interested in cost effective solutions to recover energy from ship exhaust gases.
Solutions for capturing such energy already exist, but they are capital intensive, energy inefficient, and costly to maintain. As a result, interest in investment in these kinds of systems is limited in the marine industry. Examples of existing technology includes exhaust gas boilers that generate steam to drive a turbine and direct exhaust gas turbines.
The main opportunities for recovering energy involve the waste heat and kinetic energy of the exhaust gases. The temperatures of the exhausts are in the region of 250-350 deg C and the mass flow of a typical 1MW engine is about 7 tonnes/hour.
• Technical Viability-- Solutions proposed must be based on sound scientific principles and have pilot scale data that demonstrate efficacy. Also, the associated equipment must be able to withstand the harsh environment inside an exhaust stack.
• Scale up Potential—Solutions proposed must have a clear pathway to the application on commercial ships. Solutions already practiced in marine markets have higher value. The ideal partner would be able to lead the design and installation of full-scale systems.
• Capital and Operating costs—solutions would need to provide reasonable return on investment, consistent with the 30% energy losses experienced today. The return on investment assumptions for any proposed solution should include a full life-cycle analysis (including capital/installation costs, maintenance costs, installation time, etc.)
• Ship Operations—solutions should not impact the normal operation of the ship engine. The equipment space and weight must be able to be retrofitted onto existing vessels. Moreover the equipment should not increase back pressure to the point it effects engine performance.
• Ownership—Solutions covered by patents have higher value. At a minimum, proposed solutions must not be prohibited by other patents in the field.
• Intellectual Property Requirements — None required when using exiting solutions, however where the company takes technology and creates a bespoke applied solution then patents and IP may need to be sought.
Solutions will not be considered if, in the companies opinion:
• Installation and maintenance costs are prohibitive for broad application
• Proposals lack sufficient supporting pilot scale data
• Solutions don't adhere to global maritime environmental or safety regulations
• Solutions would void guarantees from engine suppliers. Approval may be needed.
A partner is sought that can provide a way to recover and transform energy from the exhaust gases of ship engines. The partner must be able to demonstrate laboratory or pilot scale data and be able to show a clear pathway to application on commercial ships.
The client is flexible in the amount of technical involvement in the type of partnership considered. Where some development is required for the specific application considered here, the product could be developed jointly or there could be some other commercial agreement for development with technical assistance.
