McCoy Reports has singled out Mitsubishi Hitachi Power Systems, Ltd. (MHPS) as the 2018 market leader on global orders wins for heavy duty gas turbines (>100 MW). The J-series gas turbine, with its industry-leading 64% plus efficiency rating, was instrumental for MHPS’ heavy duty turbine business segment to capture over 41% market share globally.
Today’s power grids are becoming increasingly complex as more decentralized power sources are added, requiring the network to carry bulk power in ways it was never designed to do. Recent order wins for GE’s Fixed Series Compensation (FSC) total over $60 million as TSOs turn to the technology to enhance flexibility of the grid.
Burning hydrogen (H2) in a combined-cycle power plant is a step towards dispatchable, totally CO2-free power generation. However, the main challenge of H2 combustion lies in its properties, notably its increased reactivity. In contrast to natural gas, the flame position moves upstream during H2 combustion, which increases the risk of flashback.
MAN Energy Solutions will present its storage solution portfolio, including Power-to-X applications, its ETES (Electro-Thermal Energy Storage) energy management, battery-storage and hybrid systems for decentralised power generation at the ‘Energy Storage Europe’ trade fair in Düsseldorf, Germany, from March 12 to 14.
For F-class turbine operators demanding fuel flexibility retrofits, Ansaldo Energia offers a tested and commercially proven combustion system for gas turbines originally manufactured by GE, Siemens-Westinghouse and MHPS. The sequential combustor is designed specifically for the use of hydrogen (H2).
Bentley System, together with Siemens, has launched a new digital solution for substations to grid-integrate distributed energy sources. OpenUtilitiesDER Planning & Design Assessment Solutions creates a digital twin for utilities that allows operators to more efficiently model, plan and approve rising request for supply of distributed power to the grid.
Commissioned by grid operator Amprion, Siemens has built two reactive power compensation systems for the Kriftel grid node: a mechanically switched capacitor with damping network (MSCDN) and a power-electronic static synchronous compensator (STATCOM). The two systems are running stable since December in test operation.
Researchers from Kawasaki Heavy Industries (KHI) and B&B Agema have been looking at a novel design approach – Nekomimi film cooling – to further increase temperatures at the combustor exit and high-pressure turbine stage inlet. The aim is to boost efficiency without putting too much strain on vanes and blades, considering that modern turbine stage inlet temperatures exceed the melting points of turbine blade materials.
