The world needs clean, more efficient energy generation to supplement our existing energy generation assets. Industrial-scale and technology development projects are active worldwide in the emerging, next-generation power market. A common goal the projects share is to demonstrate that emerging power generation systems can provide clean, reliable power. HAYNES® and HASTELLOY® alloys are used as enabling technologies to make it possible to build and operate some of these systems. Our alloys are necessary because they can perform under demanding high-temperature, environmentally aggressive operating conditions.
This emerging market encompasses three key power generation applications:
Advanced Power Generation
Emerging technologies include supercritical-CO2 (sCO2) power cycles, advanced ultra-supercritical power plants, coal gasification, gas separation technologies for oxy-combustion and syngas production, and gas-to-liquids.
Renewables
Emerging technologies include fuel cells, concentrated solar power, photovoltaic cells, thermoacoustic engines, sterling engines, geothermal, waste fuels, and waste- and biomass-to-energy.
Advanced Nuclear
Emerging technologies include next-generation, molten salt and molten metal nuclear reactors, and gas-cooled nuclear reactors. These systems can use molten salt, molten metals, and very high-temperature gases near 850oC or higher.
As the applications in this field continue to evolve, our metallurgists can assist in the alloy selection process and provide technical support for your application.
Our Emerging Technologies Alloys:
HAYNES® 233® alloy
HAYNES® 233® alloy is a new Ni-Co-Cr-Mo-Al alloy that offers excellent oxidation resistance at temperatures to 2100°F (1149°C) or higher, depending on application, coupled with superior creep strength – a combination of properties never before achieved in a readily fabricable alloy.
