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.
Falling costs for renewables and energy storage will squeeze out gas-fired generation in some markets as early as 2025. South Australia's peak loads are currently managed by open-cycle gas turbine (OCGT) plants; but by 2025, battery storage will be cheaper than OCGTs – even at gas price of A$7/mmbtu, a WoodMackenzie study finds.
The first GT36-S5 model gas turbine produced at Ansaldo Energia's Genoa production facility was unveiled on Friday. With the ongoing support of Shanghai Electric Group, Ansaldo Energia’s Chinese partner, the first GT36 maxi gas turbines will be installed in two power generation plants in the Shanghai area.
Competition amongst battery producers is heating up: they have to shorten their time to market, improve their flexibility, quality and efficiency. To help boost the efficiency of large-scale battery production, Siemens has launched portfolio of cloud-based software solutions that help optimize every step of battery production and thus improve the competitiveness of battery manufacturers.
Funding of about $44 million has been freed up by the US Department of Energy (DOE) for design and testing of advanced carbon capture and storage (CCS) technologies. Selected projects include engineering-scale testing of transformational solvent- or membrane-based CO2-capture, and the design of a commercial-scale, post-combustion CCS system at an existing coal power unit.
Future use of hybrid energy will lead to a consistent baseload, without the need for top-up via fossil fuels, anticipates Francesco Falco, chief commercial officer at GE Power Conversion. "When using Silicon Carbide (SiC), – a diamond-like substance – instead of traditional silicon chips in a solar inverter, its high power density feature can reduce power losses by up to 50%," he explained.
Mitsubishi Hitachi Power Systems (MHPS) is celebrating its first win in Brazil for the technical selection of the M501 JAC gas turbine for the Vale Azul-II project. The power plant, which will have a contracted output of 466MW in combined-cycle mode, was successful in the A-6 Brazilian Electricity Auction held on December 20.
Dispatchable power generation capacity is shifting from flexible gas gensets to wind and solar technologies paired with energy storage. Excellent solar resources in the U.S. state of Arizona make First Solar confident that its 65MW solar farm and a 50MW/135MWh battery storage facility will outcompete gas peaking plants in terms of supplying electricity into the evening peak.
Juazeiro, a city in northeastern Brazil, will host ABB install Latin America’s first digitally-enabled substation. The new 230-kilovolt (kV) substation and connection bay at the Juazeiro II substation will deliver power from a 156-MW solar photovoltaic poewr plant, under development nearby. Arctis, a UK-based investment firm, will own and operate the Juazeiro solar project together with its renewable energy arm in Latin America, Atlas Renewable Energy.
Challenged with the rising contribution of inherently intermittent wind and solar power supply, network operators are investing billions in stabilising their power grids. To anticipate supply/demand patterns and avoid overloaded grids, GreenCom Networks has developed an “Open-innovation Lab” with live data from end-customers. The system links electric cars, PV systems, heat pumps and other energy equipment in Germany and France.
A firing test, using a 30% hydrogen fuel mix, has been successfully passed by one of Mitsubishi Hitachi Power System’s (MHPS) large-scale gas turbines. Test conditions called for a turbine inlet temperature of 1,600℃, equivalent to 700-MW of output, using the premix combustor of J-Series gas turbines.
