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.

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.

Working From Home (WFH) Effectively

In the midst of the coronavirus pandemic, working from home is the new reality for millions of US workers. Many companies are implementing voluntary or mandatory work-from-home policies, which means a lot of us are facing with an unusual challenge of working remotely for the first time and full-time.

Surely this era is different from working home for a day or two. Working from home due to coronavirus outbreak is unforeseen and could be extended for a certain period of time. You cannot easily go out and socialize in person, and are limited only to essential activities. According to Business Insider, some of the biggest challenges of remote workers include struggling with loneliness, managing their time, and communication among colleagues.

I do too, had a difficult time transitioning myself to work from home for a few weeks. Then, I came across with these tips to improve my WFH experience to stay productive and healthy while working remotely:

1. Get Dressed

Dress like you are at work, or at least from your pajama, helps even if you won’t be interacting with another person all day. By dressing up, your brain knows that it’s work time, and prepare yourself to focus effectively.

2. Designate a Home Office

It is very tempting to work from relaxed environment at home, but this could take a huge penalty on your productivity. With a designated separated workspace, you will be more alert, more confident, and more organized.

3. Keep Defined Working Hours

Just as you designate and separate your physical workspace, it is important to distinguish when you are working and when you are not. This is the important step to ensuring productivity while working from home. Setting yourself consistent hours keep you accountable and productive. Moreover, it is your best practice to keep your regular hours on the same schedule as your coworkers if your roll is collaborative.

4. Communicate and Stay in the Loop

Communication is especially important if you and your team have to go fully remote. Regularly communicate with your team when you convey any changes or new assignments to one another. If you encounter unique challenges as you try to do your job remotely, reach out to your team for your help.

5. Set Your Goals

Before you start working, a little habit of planning your work day will help your productivity up. Check what your priorities are for the day, how long you think it will take you to get everything done, and what you will work on if you have extra time.

For an example, here are the breakdowns of my new working-from-home routine:


Wake up, do some morning stretching, have a light breakfast, and dress up. About ten minutes before working, I jog down my plans for the day.

9:00AM – 12:00PM

Work, work, work! I have separated my workspace from any distraction in my house. For example, when I’m near my refrigerator, I tend to open and close the door repeatedly staying hungry. My home office is the farthest from the kitchen.

12:00PM – 1:00PM

Prepare and have a lunch, and take a short stroll around my apartment complex. I use this time to check my mail box.

1:00PM – 6:00PM

Work, work, work! Based on a short personal analysis, I am much focused between 2PM to 6PM. Every hour or so, I take few minutes to stretch my body and to look out the window so that I could rest my eyes for a bit away from the computer screen.

Following this routine helps me to stay more productive while I can keep practice healthy social distancing life.


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.

01. Advantages of Hydrogen Gas Turbines
02. Pre-Conditions of a Hydrogen Power Plant
03. Hydrogen Combustion
04. Retrofit of Existing Gas Turbines
05. 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.
