Over the last century, the gas turbine sector has changed dramatically. Improved efficiency, lower emissions, and increased output have been the driving forces in the power generating market, whereas reduced weight and smaller size have been the driving forces in the aerospace business. Hydrogen is been the topic in recent years for turbine construction.
The initial layout and overall balance of the plant, as well as the required hydrogen concentration in the fuel, dictate the amount of the modifications required to convert a gas turbine to run on hydrogen.
The Evolution of Hydrogen Combustion
Previously, coal was used to boil water and superheat steam. And then extend it to generate electricity via a turbine/alternator. The Rankine Cycle is a type of power generation that has been around for a long time.
The gas turbine arrangement involves burning natural gas in compressed air, extending the hot combustion products through a power turbine. And using the shaft power to drive both the compressor and the generator (Brayton Cycle).
Raising steam and producing additional electricity in a turbine/alternator using hot exhaust gases can provide additional energy. And “Combined Cycle Gas Turbine” is the name for this combination (CCGT).
Large Gas Turbines
Depending on the type of combustor installed, the larger devices have varied capabilities for natural gas/hydrogen mixes. Siemens has tested its F-class machines with hydrogen levels ranging from 30% to 73 percent in the fuel gas. Hydrogen Gas Turbines with a High Volume
Many major power equipment manufacturers are constructing gas turbines that run on a high-hydrogen-volume fuel. This is to prepare for a large-scale power sector move toward decarbonization.
According to several experts, efforts by companies like Mitsubishi Hitachi Power Systems (MHPS), GE Power, Siemens Energy, and Ansaldo Energia to build 100 percent hydrogen-fueled gas turbines have recently accelerated. Thanks in part to new carbon reduction policies around the world that have accelerated renewables capability. The companies, which all make large gas turbines but are competing for a smaller market share, are also vying for a foothold in emerging markets. Such as those that could thrive in a hydrogen economy, which makes preparations for a Hydrogen Society
MHPS, a joint venture between Mitsubishi Heavy Industries and Hitachi, has been vocal about its efforts to comply with Japan’s aspirations to become a “hydrogen society,”.
Control system for Gas Turbines
The gas turbine control system helps the technical professionals by adding security improvements. It is in the area of lowering fuel emissions by properly indicating insecure operations. Turbine control systems cover excessive fuel emissions, fuel control, and vibration monitoring. Turbine control system parts include IS200DRLYH1A, IS200DRTDH1A, etc.
Hydrogen Gas Turbines for Future
The challenge with hydrogen gas turbines is that they must function without losing starting times, NOx emissions, or performance.
Gas turbines will be able to satisfy the market’s needs as the hydrogen economy expands over the next decade without compromising today’s high-performance standards in terms of emissions, response, and productivity.
