Much ado has been made over an oxidation issue at GE HA turbine blades at Exelon’s Colorado Bend power plant near Houston. Keen to limit the reputational damage, the top management of GE Power underlined the issue is limited to 9FB and HA gas turbine Stage 1 Blades. Not impacted are Advanced Gas Path (AGP) upgrades for the B/E/F-fleets, and the new HA or 9F.05 order.
With the launch of P9394GSI S5, rated at 2,500 horsepower, GE Distributed Power is adding another model to its Waukesha VHP Series-5 family of rich-burn gas engines. The new S5 engine has an improved cylinder head, piston/ring design, Miller-cycle combustion and Waukesha’s latest ESM-2 engine controls.
Toshiba Energy Systems & Solutions (ESS) has started a survey to develop applications and use of its hydrogen-based H2One energy supply system, targeting isolated regions on islands in Indonesia and the Philippines. H2One utilizes renewable energy and hydrogen-powered fuel cells to deliver CO2-free electricity and hot water supply.
DynaGridCenter, developed by Siemens and partners in industry and research, has been launched as a next-generation control system. Prof. Dr. Rainer Krebs, head of operation and protection of Power Grids at Siemens Energy said: "In the future, we'll need control centers that can independently regulate the highly dynamic power grid with an autopilot functionality and keep it stable." A dynamic control center is therefore an “indispensable part of a successful energy transition.”
Turboden has been contracted by Brescia’s municipal dairy producer to install its first high-temperature cogeneration, Organic Rankine Cycle (ORC) turbogenerator-based power plant in the world. With an efficiency of more than 90% and high prevalence of steam content, the steam & power ORC system has been developed especially for the manufacturing industry.
Oxidation, discovered with a single blade component of GE turbines, have forced Exelon Corp to idle four units in a gas-fired power station in Texas. GE Power CEO Russel Stokes disclosed the oxidation could affect over 50 of its high-efficiency HA turbines and 75 of 9FB gas turbines, with the news casting a further shadow over the manufacturer’s ailing turbine business.
Siemens and E.ON have reached a milestone in the area of 3D-printing, with the world's first 3-D printed burner for an SGT-700 gas turbine having been in operation for one year at E.ON's combined-cycle power plant in Philippsthal, Germany. “The results are impressive,” Siemens said given that “the burner has been operating for over 8,000 hours with no reported issues.”
Researchers at MIT, the Tokyo Institute of Technology and BMW’s Battery Technology Lab have found the vibrational frequency of lithium can be fine-tuned by tweaking its lattice structure through chemical substitution to alter structural arrangements of atoms. The new concept provides a powerful tool for developing new, better-performing materials that could increase the amount of electricity stored in a battery.
GE’s Power Services has announced the launch of its first 6B repowering solution when signing the first agreement for the solution with a global chemical company in Asia. The accord stipulates the repowering of three 6B gas turbines which is expected to help the customer save significant amounts of fuel.
