DOE team elucidates key hydrogenation mechanism of magnesium diboride; promising solid state H2 storage material
http://www.greencarcongress.com/2017/09/20170928-llnlh2.html

An inexpensive and useful layered superconductor compound also may be an efficient solid-state material for storing hydrogen. Through theory and experimentation, Lawrence Livermore National Laboratory (LLNL) scientists, with colleagues at Sandia and Lawrence Berkeley national laboratories, have discovered the key mechanism by which magnesium diboride (MgB2) absorbs hydrogen and provided key insights into the reaction pathway that converts MgB2 to its highest hydrogen capacity form, magnesium borohydride (Mg(BH4)2).

Mg(BH4)2 is a particularly promising hydrogen storage material because of its high hydrogen content and attractive thermodynamics.

    The current generation of fuel cell light duty vehicles use high-pressure (700 bar) “composite over-wrapped pressure vessels” (i.e. composite tanks) to store the hydrogen fuel. While enabling the roll-out of light duty fuel cell vehicles, 700-bar composite tanks are not optimal and alternative hydrogen storage systems/materials/approaches can, in principle, provide significantly improved gravimetric and volumetric storage densities.

    Metal hydrides and other solid-state materials offer potential advantages for hydrogen storage, such as higher gravimetric and volumetric storage densities, filling from lower pressure hydrogen sources (thus avoiding compression energy losses), and added safety stemming from a typically order of magnitude lower overall hydrogen storage pressure. However, metals hydrides that posses the high gravimetric and volumetric storage densities have not demonstrated adequate cyclability and fast refueling under practical conditions To identify causes of these limitations and strategies to mitigate them, a better microscopic characterization of these materials during hydrogenation and dehydrogenation must be obtained.

VW Group Steps Back From Fuel Cell Plans, Will Focus On Electrification
https://insideevs.com/vw-group-steps-back-from-fuel-cell-plans-will-focus-on-electrification/

t’s safe to say Volkswagen CEO, Matthias Mueller, was more than eager to talk about the group’s massive eco-friendly agenda presented earlier this month at Frankfurt Motor Show: 80 new electric vehicles by the middle of the next decade, $24-billion investment in EVs, and a zero-emissions derivative of all 300 group models by 2030.

It was an entirely different story when he was asked about the prospects of hydrogen vehicles as his answer was rather succinct by only saying Audi will have a fuel cell model “one of these days.” The Ingolstadt-based marque has been the driving force behind FCVs within the group, so it doesn’t come as a surprise Audi will be the first to use it for a production model. . . .

But Audi of America president, Scott Keogh, considers EVs to be more important: “The worst thing you can do is kind of half bake electric, then go off on another science project with fuel cells, then go running to another science project.”

As Automotive News points out, the VW Group’s decision to take a step back from pursuing hydrogen fuel cell hardware could have a greater impact as there is a chance it will discourage the adoption of FCVs. That being said, other automakers are not giving up just yet as aside from current cars like the Honda Clarity and Toyota Mirai, new fuel cell models are on their way.

Mercedes unveiled at the same Frankfurt show a near-production version of the plug-in hybrid GLC F-Cell, while Lexus is expected to come out with an LS fitted with the same type of propulsion. In addition, BMW has been working on this technology for quite some time and it will launch a low-volume model in 2021. Meanwhile, Hyundai’s next-generation fuel cell system will land in 2018.

This was a bad week to be in the hydrogen car business.

Besides VW bowing out of the hydrogen game (sorry, "science project"), Toyota has announced a joint venture with Mazda to make... EVs!

Yes, the same Toyota that has spent much of this decade poo-pooing EVs. Obviously, Toyota will still ride the hydrogen wave for as far as it will go (and it's not far), with Japan wanting to show the world how advanced they are with hydrogen cars at the 2020 Olympics (like Canada did in Vancouver in 2010... and those hydrogen buses are LOOOOoooong gone).

I don't expect the Toyota / Mazda consortium to be anything more than a regulatory game, but it's obvious that they aren't planning on meeting future ZEV requirements in China and California with just a hydrogen game plan.

With all the money thrown at EVs in the past week; Daimler / Mercedes Benz to spend $11billion, Dyson to spend $2, VW to spend up to $85 billion, China to go all EV (they aren't too fond of hydrogen over there), California talking about all ZEV, numerous European countries and cities talking about ZEV futures... yep, I wouldn't want to be the hydrogen lobbyist's dog. You just might take a boot in the rib cage this week.

Don't fret, though. I absolutely guarantee that our state will be throwing at least $20 million a year for the next 8-10 years, regardless of whether there are ANY hydrogen cars.

California workshop on hydrogen and fuel cells in ports
http://www.greencarcongress.com/2017/09/20170930-h2ports.html

The California Hydrogen Business Council (CHBC) is hosting a one-day workshop to discuss the current hydrogen and fuel cell activities in ports and maritime, hear the needs and challenges from port and maritime customers (port authorities, terminal operators, trucking companies) of California Ports to reduce their emission footprint and meet California state air quality requirements.

This workshop is the follow-up to the Hydrogen and Fuel Cells in the Ports Workshop 2016, held in Port of Los Angeles. At this year’s workshop, there will be updates from last year with presentations from ports authorities, terminal operators, trucking companies, hydrogen and fuel cell technology providers, and State funding agencies. . . .

Hydrogen-fueled fuel cell electric vehicles are expanding in the California light duty vehicle market, and hydrogen fuel cell fork lifts and other products are being commercially purchased by product distribution centers and factories today. California programs in different stages of development will have an impact on the transition to hydrogen energy systems, including the Sustainable Freight Action Plan and Clean Air Action Plans. Hydrogen and fuel cell systems will have to meet the economic and performance requirements of the terminal operators to find market acceptance in the ports.


DOE Fuel Cell Technologies Office to host a fuel cell car ride-and-learn at ECS 232
http://www.greencarcongress.com/2017/09/20170930-fcto.html

The US Department of Energy (DOE) Fuel Cell Technologies Office (FCTO) is hosting a Ride-and-Learn at the 232nd Electrochemical Society (ECS) fall meeting next week at the Gaylord National Resort and Convention Center in Maryland. The Ride-and-Learn is open to all ECS attendees, first come, first served.

DOE is also providing an update on hydrogen and fuel cell cars at the Polymer Electrolyte Membrane Fuel Cell Plenary Session.

FCTO has funded early-stage hydrogen and fuel cells research and development enabling a 60% reduction in fuel cell cost, a four-fold increase in fuel cell durability, and an 80% cut in the cost of electrolyzers over the past decade.

GM to introduce at least 20 new EVs by 2023; 2 in next 18 months; batteries and fuel cells; SURUS
http://www.greencarcongress.com/2017/10/20171002-gm.html

. . . Given customers’ various needs, getting to a zero emissions future will require more than just battery electric technology. It will require a two-pronged approach to electrification—battery electric and hydrogen fuel cell electric depending on the unique requirements. . . .

GM also introduced SURUS—the Silent Utility Rover Universal Superstructure—a fuel-cell-powered, four-wheel steer concept vehicle on a heavy-duty truck frame that’s driven by two electric motors. With its capability and flexible architecture, SURUS could be used as a delivery vehicle, truck or even an ambulance.


easyJet and Wright Electric: all-electric short-haul flights within a decade

BUR airport has had electric tugs for a few years at least. Tugs seem like an area where the weight of lead acid (or any other battery really) is an advantage. Do they really need the range of fuel cells for a tug?
