World’s First Integrated Hydrogen Power-to-Power Demonstration Launched

A consortium of European companies, research institutes, and universities have launched the world’s first demonstration of a fully integrated power-to-hydrogen-to-power project, at industrial scale and in a real-world power plant application.

The four-year project to demonstrate HYFLEXPOWER, which has achieved a technology readiness level of 7, will convert a 12-MWe combined heat and power (CHP) plant at Engie Solutions’ Smurfit Kappa pulp-and-paper industrial site in Saillat-sur-Vienne, France, to demonstrate the entire power-to-hydrogen-to-power cycle.

Advanced combustion-dynamics monitoring detects impending combustor failure, prevents forced outage

Together with Electric Power Research Institute (EPRI) and ENMAX Energy, Turbine Logic published an article called “Advanced combustion-dynamics monitoring detects impending combustor failure, prevents forced outage” to Combined Cycle Journal (CCJ).

Editor’s note is provided here:

This article introduces a novel combustion-dynamics monitoring (CDM) algorithm and a case study to demonstrate its successful detection of a gas-turbine combustor fault which otherwise might have done extensive damage to both the combustor and hot-section components. Failures of this type often develop from small, insipient faults which produce subtle signatures in the dynamics data.

Fault signatures can be detected by advanced monitoring algorithms to identify them before parts fail and force the unit out of service. The CDM algorithm described here blends data analytics and combustion domain expertise with existing combustion monitoring data. It currently is fielded on a fleet of frame units and has successfully caught several faults at sufficiently early stages to plan repairs without a forced outage.

Offshore Wind Finding Direction in U.S.

Europe has a big head start globally when it comes to generating power from offshore wind installations. The U.S. has lagged due to a variety of factors, including the need to work through regulatory issues. Industry insiders, though, agree the sector is poised for rapid growth off American shores.

Offshore wind installations already are delivering on their promise as a transformative technology for power generation, with projects off European coasts providing proving grounds for the industry. U.S. adoption of offshore wind has been slower, owing in part to regulatory issues and political will.

Darrel Procter, an associate editor for POWER Magazine, discusses several lag factors observed in wind installations in US shores, economic impacts of US offshore wind power, new technologies that drives growth in offshore wind, and potential growth in the field alongside with emerging trend of using hydrogen as an energy source.

EIA: Wind, gas and solar add combined 22.7 GW of new capacity in 2019

Onshore wind projects led all new electric power capacity added in the U.S. last year, according to a new report by the federal Energy Information Administration.

According to statistics complied in the EIA’s latest Monthly Electric Generator Inventory Report, the nation’s electric power sector installed nearly 23,000 MW of new generating capacity  in 2019. Onshore wind was tops in new additions with 9,100 MW.

Utah plans first-of-a-kind 100% renewable hydrogen plant

Utah took a step forward yesterday in switching a coal plant to 100% renewable hydrogen — a plan that would allow Los Angeles to be the first U.S. city powered by the fuel.

Tokyo-based Mitsubishi Hitachi Power Systems (MHPS) announced a contract yesterday with Utah’s Intermountain Power Agency (IPA) for a gas turbine technology that will help a coal-fired power plant in central Utah gradually transition to using renewable hydrogen for electricity. Renewable hydrogen is created when renewable energy is harnessed to split water molecules.

MHPS Secures First Order for Hydrogen-Capable J-Series Gas Turbines

Mitsubishi Hitachi Power Systems (MHPS) has ordered for the first advanced-class gas turbine, which is designed to transition of Utah’s Intermountain Power Agency (IPA) to renewable hydrogen fuel. Purchase of MHPS’s advanced J-series gas turbines is a part of IPA’s Intermountain Power Project (IPP) to sequentially transition from coal to natural gas and ultimately to renewable hydrogen fuel by 2045.

The M501JAC gas turbine is the company’s latest J-series air-cooled (JAC) model, which applied steam cooling to the combustor and raised its turbine inlet temperature (TIT) to 1,600C and efficiency to 62%. It also features an optimized cooling structure for the blades and vanes to have 64% combined cycle efficiency, which makes it well-suited to an eventual conversion to 100% hydrogen.

According to MHPSA President and CEO Paul Browning, the M501JAC units will be guaranteed to be able to combust a mix of 30% hydrogen and 70% natural gas starting in 2025. Between 2025 and 2045, the fuel mixture will be systematically increased to 100% renewable hydrogen, while MHPS is still developing a combustion technology that will be capable of firing 100% hydrogen fuel.

ETN Hytrogen Gas Turbines – 05 Current Capabilities of Gas Turbines Burning Hydrogen

This week’s blog post is the last series of reviewing ETN Global’s recently published a new report, entitled “ETN Hydrogen Gas Turbines – The Path Towards a Zero-Carbon Gas Turbine.”  The main objectives of this report is to highlight potential benefits and challenges on the hydrogen uses in gas turbines. The report also assesses preconditions to the implementation of a hydrogen power plant, requirements for retrofit of existing gas turbines, and current capabilities of gas turbines burning hydrogen.

05. Current Capabilities of Gas Turbines Burning Hydrogen

In this chapter, ETN provides an overview of the currently acceptable share of hydrogen contents that can be burned in gas turbines. ETN discusses that major work still remains to be done in order to qualify gas turbines for high hydrogen content gaseous fuels, even though considerable efforts have been put by all gas turbine manufacturers. Major experience with high hydrogen content fuels has been accumulated with gas turbine products developed for the combustion of syngas with a H2 concentration rangebetween 30 to 60% vol. of H2.

Majority of gas turbines OEMs developed for syngas applications can be adapted to run on natural gas and hydrogen mixtures with significantly high hydrogen content (60% to 100%). Though these gas turbine engines require special combustion technology such as diffusion burner, dilution with N2 and/or steam, and water inject, in order to cope with challenges of hydrogen combustion, often still does not meet lower NOx emission levels.

Thus, ETN emphasizes the ultimate research and development target is the achievement of state-of-the-art low NOx emissions, less than 25ppm, with fuel gas mixtures contents by increasing amounts of hydrogen from electrolysis up to 100% H2.

The current dry low emission (DLE) combustion techniques are the main R&D subject to base new and modified combustion technologies. With such adapted DLE combustion systems OEMs successfully tested gas turbine products operated with fuel gas mixtures with up to 20% to 30% vol. of hydrogen.

More detailed overview per OEM is given in ETN’s full report on Hydrogen Gas Turbines. This report can be found in Here.
