A lifecycle upgrade enhances the equipment of a power plant to meet its original running parameters. With a combined cycle upgrade, more power can be produced with the same amount of fuel by applying waste heat recovery steam generators connected to common steam turbine generator sets. According to Wärtsilä Services Manager Markus Åbrant, this particular type of upgrade can trigger as much as 10% higher energy output.
Development of practical fusion power plants has been slow-moving, but now researchers at the Massachusetts Institute of Technology (MIT) have found an innovative solution on how to get rid of excess heat that would cause structural damage to the plant. The new MIT-originated design features secondary magnets and an enlarged exhaust pipe.
Having just launched H2 solution, its new sequential hydrogen combustion system, Ansaldo Energia is now carrying out further tests with the aim of allowing gas turbines to run entire on renewable gas. “The latest H2 solution is already capable to work in an impressive load range, and with still unmatched hydrogen volume percentages,” the Italian manufacturer stated.
Japan’s Toshiba Energy Systems & Solutions (ESS) has agreed with the National Electrification Administration (NEA) of the Philippines to jointly promote H2One – autonomous, hydrogen-based energy systems and the use of hydrogen as a fuel for power generation. In a study, both partners will evaluate the optimum system specifications in the Philippines, where half of the current energy supply is comes from coal-and oil-fired power stations.
Southwest Research Institute (SwRI), together with research and industry partners, has started construction of a supercritical carbon dioxide (sCO2) power plant in San Antonio, Texas. The $119 million pilot project is also supported by GE Global Research, the Gas Technology Institute (GTI) and the US Department of Energy/National Energy Technology Laboratory (DOE/NETL). Construction is slated to be completed in 2020.
Looking to converge digital engineering models, Siemens and Bentley Systems have entered a strategic alliance on project delivery and asset performance for the sectors Energy Management, Power Generation, Building Technology and Mobility. Siemens had acquired about € 70 million of secondary shares in Bentley, and the two companies now said they will invest at least € 50 million in developing joint digital solutions for infrastructure and industry.
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.”
