Development Opportunities for Particulate Materials and Products in Power Generation

The Future of Power Generation – The Role of Particulate Materials report identifies key development opportunities for particulate materials and products in power generation, transformation, transmission, distribution and storage industries. The report covers ceramics, powder metals, hard metals and magnetic materials .

The study covers plant and equipment for:

• Fossil-fuelled combustion generation technologies
• Nuclear Power Generation
• Water Power Generation technologies
• Power generation from other renewable sources
• Fuel cell technologies
• Power transformation, distribution and storage systems

Recommendations Made in the Report

The report's recommendations could make significant contributions in satisfying the future performance needs of the energy sectors, forecast to grow significantly in the next 25 years in order to meet stringent environmental requirements.

Highlighted development areas include:

• Improved surface engineering solutions
• Novel metal deposition technologies
• Powder consolidation techniques
• High performance, protective NdFeB magnet coatings
• Improved performance refractory lining materials

Improved Surface Engineering Solutions

The supply chain that utilises particulate feedstocks in surface coatings (e.g. in thermal spraying, laser deposition) should work with OEMs in combustion technology plant (boilers, steam turbines, gas turbines, gasifiers) to develop surface engineering solutions to combat increasingly arduous requirements in thermal barrier protection; resistance against oxidation, corrosion, erosion and deposition problems; and sealing. For new plant build in the medium term, there should be an increasing emphasis on developing the surface coating and substrate as a unified system.

Novel Metal Deposition Technologies

Novel metal deposition opportunities should be pursued in the increasingly important area of repair, refurbishment and life extension of existing combustion technology plant and hydroelectric turbines.

Powder Consolidation Techniques

Powder consolidation techniques should be pursued for the manufacture of enhanced materials for gas- and steam-turbine components, to provide compositions and microstructural control not achievable in conventional processing or for the cost-effective net-shape manufacture of components with particularly low material utilisation factors in conventional processing. This may, as a longer term objective, incorporate work on ceramic matrix composite materials for gas-turbine combustor component applications.

Improved Performance Refractory Lining Materials

The development of enhanced performance refractory lining materials should be pursued in order to serve the future durability requirements of gasification chambers.

High Performance, Protective NdFeB Magnet Coatings

The development of enhanced coatings for the corrosion protection of high performance rare earth permanent magnets (Nd-Fe-B) and the further development of alloy systems for such materials to enhance their long-term magnetic stability should be pursued, so that significant niche market opportunities in direct drive generator systems in off-shore wind farms and certain wave/tidal technologies can be exploited.

Solid Oxide Fuel Cells

Further development of ceramic materials and processing routes for solid oxide fuel cell electrolytes should be pursued, in order to reduce the manufacturing costs of such devices, enhance reproducibility/consistency of performance and aid scaling up.
