First UAV test flight with Cella solid-state hydrogen storage and fuel-cell power system
February 08, 2016
The Scottish Association for Marine Science (SAMS) recently completed a UAV test flight using Cella Energy’s hydrogen-based power system. The system is based on Cella’s solid, nanostructured chemical hydride hydrogen storage material which is capable of releasing large quantities of hydrogen when heated. Cella Energy is a spin-off from STFC’s Rutherford Appleton Laboratory in the UK. (Earlier post.)
Cella designed and built a gas generator using this material, which when combined with a fuel cell, creates electrical power. The complete system—Cella gas generator along with a fuel cell supplied and integrated by Arcola Energy—is considerably lighter than the lithium-ion battery it replaced.
Researchers find some solid-state hydrogen storage materials could serve as less toxic solid propellants for rockets
January 25, 2016
Researchers in China have found that amine metal borohydride—a novel hydrogen-enriched boron–nitrogen–hydrogen (BNH) hydrogen storage system—has potential as a solid propellant or additive for solid and hybrid rockets.
In a paper in the ACS journal Energy & Fuels, they investigated the combustion properties of two newly developed ethylene diamine aluminum borohydrides (Al(BH4)3·nEDA, n = 3, 2). They found the materials have high combustion heat of 32.20 and 36.90 MJ/kg for Al(BH4)3·3EDA and Al(BH4)3·2EDA, respectively, with ignition delay times of ∼2.0 ms.
PNNL team scales up ammonia borane slurry for on-board H2 storage for automotive applications
December 26, 2015
A team at Pacific Northwest National Laboratory (PNNL) is scaling up their work on the use of ammonia borane (AB) slurries optimized with an ultrasonic process for automotive hydrogen storage applications. Ammonia borane is an atttractive material for chemical hydrogen storage (CHS) due to its high hydrogen content of 14–16 wt % below 200 °C.
CHS materials release hydrogen at low temperatures but are not easily rehydrided as are metal hydrides, needing instead to use chemical regeneration. In work reported earlier this year (Choi et al.), the PNNL team optimized a model AB slurry in silicone oil, obtaining up to 40 wt % (ca. 6.5 wt % H2) loading. The US Department of Energy (DOE) gravimetric target for on-board hydrogen storage is near 10 wt %. In the current work, reported in the ACS journal Energy & Fuels, the team optimized the slurry production to prepare 50 wt % (ca. 8 wt % H2) AB slurries and proceeded toward making liter-size batches to show scalability.
DOE releases three reports showing strong growth in US fuel cell and hydrogen technologies market
December 24, 2015
The US Department of Energy (DOE) released three new reports today showcasing strong growth across the US fuel cell and hydrogen technologies market. According to these reports, the United States continues to be one of the world’s largest and fastest growing markets for fuel cell and hydrogen technologies.
With support from the Energy Department, its national laboratories and private industry have already achieved significant advances in fuel cell and hydrogen technologies, resulting in reduced costs and improved performance. These research and development efforts have helped reduce automotive fuel cell costs by more than 50% since 2006 and by more than 30% since 2008. At the same time, fuel cell durability has quadrupled and the amount of expensive platinum needed in fuel cells has decreased by 80 percent in the last decade.
Purdue, EPFL team propose Hydricity concept for integrated co-production of H2 and electricity from solar thermal energy
December 16, 2015
Researchers from Purdue University and École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland are proposing a new integrated process involving the co-production of hydrogen and electricity from solar thermal energy—a concept they label “hydricity”. They describe their proposal in a paper in the Proceedings of the National Academy of Sciences (PNAS).
The hydricity process entails integrating solar water power (SWP) cycle and solar thermal hydrogen production technologies and a turbine-based hydrogen power cycle with suitable improvements of each for compatibility and beneficial interaction.

New Pd-based nanomaterial catalyst breaks down formic acid to H2; boost for practical chemical H2 storage
September 24, 2015
Researchers at Japan’s National Institute of Advanced Industrial Science and Technology have developed a simple method for producing a palladium-based nanomaterial that can spur the breakdown of formic acid (FA) into hydrogen and carbon dioxide. Its efficiency far exceeds that of any other reported heterogeneous catalyst, they say. They also found that their process produced carbon dioxide and hydrogen without carbon monoxide contamination, which has been a problem with other methods.
In a paper in the Journal of the American Chemical Society, they suggest that the results open up new avenues in the effective applications of FA for hydrogen storage, including on-board storage for fuel cell vehicles.

DLR techno-economic valuation of power-to-liquids finds reducing electrolyzer and electricity costs key to cost-competitive liquid hydrocarbons
July 20, 2015
In 2012, the Helmholtz Association of German Research Centers launched a three-year project on the production of synthetic liquid hydrocarbons from electricity (i.e. Power-to-Liquids, PtL) using a multistage process (SynKWS), in cooperation with the German Aerospace Center (DLR) – Institute of Combustion Technology Stuttgart; the University of Stuttgart IFK; and the University of Bayreuth – Chair of Chemical Engineering.
As part of the SynKWS work, DLR researchers have now published a techno-economic study of a modeled PtL process in the journal Fuel. The multi-stage process uses renewable power to produce hydrogen using a proton exchange membrane (PEM) electrolyzer. The hydrogen from electrolysis and CO2, delivered by a pipeline, are fed to a plant where the gases are converted in a reverse water–gas shift (RWGS) reactor to syngas (H2 and CO). The syngas is then further converted to hydrocarbons using Fischer-Tropsch (FT) synthesis. The hydrocarbon syncrude is upgraded and separated from unreacted feed and gaseous hydrocarbons to make the final product.
Fukushima launching power-to-gas hydrogen project with MCH as hydrogen carrier; supply center by 2016
Fukushima and the Fukushima Renewable Energy Institute (FREA) have launched a power-to-has project with a view to making the prefecture a hydrogen supply center by as early as 2016, according to a report in The Japan Times, via Fukushima Minpo. The project will test and refine a model of hydrogen-supply infrastructure, which would then be used in creating a functioning supply center.
The project is a collaboration between the prefecture and the National Institute of Advanced Industrial Science and Technology (AIST), the parent of FREA. AIST established FREA in April 2014 to promote R&D into renewable energy. FREA has two basic missions: the promotion of R&D into renewable energy, which is open to the world; and making a contribution to industrial clusters and reconstruction.
Total hydrogen station in Munich first to feature standard compressed H2 and BMW cryo-compressed H2 technology
July 16, 2015
Total has opened a hydrogen filling station on Munich’s Detmoldstraße. The station, which completes the European HyFIVE project’s South Cluster—comprising Stuttgart, Munich, Innsbruck and Bolsano—is the first public filling station at which the two pumps dispense hydrogen using two different types of refueling technology: industry-standard 700 bar CGH2 hydrogen storage technology (SAE J2601); and cryo-compressed hydrogen storage technology (CCH2).
Cryo-compressed hydrogen storage, being developed by the BMW Group based on its long experience with cryogenic storage, involves storing gaseous hydrogen at low temperature on board the vehicle at a pressure of up to 350 bar. It is currently at the advanced development stage and will only come on stream for general use over the longer time frame. CCH2 tanks offer up to 50% more hydrogen storage capacity than 700 bar tanks and can support a driving range of more than 500 kilometers (310 miles).
BMW shows future drive technologies; 2 Series PHEV prototype, direct water injection in 3-cyl. engine, and fuel cell eDrive
July 02, 2015
During a driving event at the Miramas proving grounds in southern France, BMW presented future drive technologies, including the prototype of a BMW 2 Series Active Tourer with plug-in hybrid drive. This application of BMW eDrive technologies features the first PHEV system with a front/transverse-mounted combustion engine, high-voltage generator and road-linked all-wheel drive via an electric drive system at the rear axle.
The company also showcased the use of direct water injection to enhance the efficiency of combustion engines at higher performance levels while also significantly reducing fuel consumption and emissions in key driving cycles. Finally, BMW showcased a hydrogen fuel cell drive system as a future-focused variant of BMW eDrive (teased in a technical session during April’s SAE World Congress in Detroit) enabling all-electric driving with a high operating range and short refueling times. (BMW is collaborating with Toyota on fuel cell systems. Earlier post.)
Study of size-dependent properties of Mg nanoparticles in H2 storage suggests path to better performance; potential for better on-board tanks
July 01, 2015
Although magnesium hydride (MgH2) is a promising solid-state hydrogen storage material, its slow hydrogen sorption kinetics have limited its application. Recent studies have shown, however, that with smaller Mg particles, the sorption kinetics improve. Since volume change during sorption generates stress, leading in turn to plastic deformation, the fundamentals of the mechanical deformation of the Mg particles are a significant issue.
Now, researchers from China and the US, including a colleague from GM R&D, have used in situ transmission electron microscopy to elucidate the size-dependent mechanical properties of Mg nanoparticles used for hydrogen storage. The team tested different sized nanoparticles to gauge their mechanical properties and discovered lessons on how one might engineer the nanoparticles to improve their performance. Their paper is published in the journal Applied Physics Letters.
McGill team develops simple system for reversible H2 storage using organic cyclic hydrocarbons; alternative route to solar fuels
June 15, 2015
A team at McGill University in Canada has developed a reversible hydrogen storage/release system based on the metal-catalyzed hydrogenation and photo-induced dehydrogenation of organic cyclic hydrocarbons at room temperature. The system, they suggest in a paper published in the Journal of the American Chemical Society, provides an alternative route to artificial photosynthesis for directly harvesting and storing solar energy in the form of chemical fuel.
The system easily switches between hydrogen addition (>97% conversion) and release (>99% conversion) with superior capacity of 7.1 H2 wt% using a rationally optimized platinum catalyst with high electron density, simply regulated by dark/light conditions. In a paper published in the Journal of the American Chemical Society, the researchers reported that the photodriven dehydrogenation of cyclic alkanes gave an excellent apparent quantum efficiency of 6.0% under visible light illumination (420–600 nm) without any other energy input.
DOE Hydrogen and Fuel Cell Program Annual Merit Review Awards
Each year, at the US Department of Energy’s (DOE) Annual Merit Review and Peer Evaluation Meeting, the Hydrogen and Fuel Cells Program presents awards for contributions to the overall efforts of the Program and to recognize achievements in specific areas. At last week’s merit review meeting, DOE made awards to 13 engineers and researchers.
Hydrogen and Fuel Cells Program Awards. DOE awarded two Hydrogen and Fuel Cells Program awards: one to George Parks of Fuel Science, the other to Jesse Schneider of BMW. (Schneider also recently received the 2015 James M. Crawford Technical Standards Board Outstanding Achievement Award from SAE for his work on hydrogen standards.)
SAE World Congress panel highlights progress on H2 infrastructure and fuel cell vehicle commercialization
May 12, 2015
Although the SAE World Congress has been running panel sessions on fuel cell vehicle commercialization since 2005, this year was the first in which three participating automakers—Toyota, Hyundai and Honda—had fuel cell vehicles that customers can buy now or within a year. (Earlier post.) Many other OEMs are also working on development of fuel cell vehicles as well.
The PFL 799 technical executive expert panel at this year’s world Congress, chaired by Jesse Schneider (from BMW), invited those automakers as well as infrastructure leaders to discuss their progress in fuel cell technology and hydrogen infrastructure and challenges remaining. Participants included Hyundai, GM, Honda, Toyota, Linde and Air Liquide.
HRL Labs video demonstrates principle of thermal battery based on advanced metal hydrides for EV heating and cooling
April 30, 2015
In 2011, the Advanced Research Projects Agency - Energy (ARPA-E) awarded $2.7 million to a team comprising researchers from the University of Utah, HRL Laboratories and GM Global R&D for a project to develop a new generation of high-density thermal battery based on advanced metal hydrides. (Earlier post.) The goal of the project, part of ARPA-E’s HEATS (High Energy Advanced Thermal Storage) portfolio, was to develop a compact thermal battery for climate control in electric vehicles. Such a thermal battery would provide heating and cooling without draining the electric battery, in effect, extending the driving range of EVs per electric charge.
As described in a paper in press in the Journal of Alloys and Compounds, the developed system uses a pair of thermodynamically matched metal hydrides as energy storage media: (1) catalyzed MgH2 as the high temperature hydride material, due to its high energy density and enhanced kinetics; and (2) TiV0.62Mn1.5 alloy as the matching low temperature hydride. HRL has now released a video demonstrating the principle behind the work on thermal battery technology.

The Toyota papers were part of a larger World Congress technical session on practical hydrogen fuel cell technology: PFL 720, Advances in Fuel Cell Vehicle Applications, chaired by Jesse Schneider of BMW.
Self-propelled catalytic microparticles boost hydrogen release from liquid storage media
April 27, 2015
Researchers at the University of California San Diego (UCSD) have developed catalytically active micromotors that significantly increase the release of hydrogen from liquid storage media. In a paper in the journal Angewandte Chemie, they introduce their new concept with a model vehicle powered by a hydrogen–oxygen fuel cell.
The new motion-based H2-generation concept relies on the continuous movement of Pt-black/Ti Janus microparticle motors in a solution of sodium borohydride (NaBH4). The autonomous motion of catalytic micromotors in the NaBH4 solution and their effective bubble generation provide a favorable hydrodynamic environment that significantly enhances the fuel supply to the catalytic surface, and thus to rapid H2 generation, compared with that obtained from a static catalyst: about 9.2-times more rapid.

March 03, 2015
The US Department of Energy (DOE) announced (DOE-FOA-0001224) up to $35 million in available funding to advance fuel cell and hydrogen technologies, and to enable early adoption of fuel cell applications, such as light duty fuel cell electric vehicles (FCEVs). (Earlier post.)
As FCEVs become increasingly commercially available, the Energy Department is focused on reducing the costs and increasing technical advancements of critical hydrogen infrastructure including production, delivery, and storage. This Funding Opportunity Announcement (FOA) covers a broad spectrum of the Fuel Cell Technology Office (FCTO) portfolio with areas of interest ranging from research and development (R&D) to demonstration and deployment projects.
DOE FCTO selects 11 fuel cell incubator projects for up to $10M in awards; exploring alkaline exchange membrane FCs
February 26, 2015
The US Department of Energy (DOE) Fuel Cell Technologies Office (FCTO) has selected 11 projects to receive up to $10 million in funding through the fuel cell technology incubator FOA (earlier post) in support of innovations in fuel cell and hydrogen fuel technologies. The intention of these selections is to identify high-impact technologies that are not already addressed in FCTO’s strategic plan or mainstream project portfolio.
The selected projects will support research and development efforts to address critical challenges and barriers for hydrogen and fuel cell technology development. The projects selected have the potential significantly to lower the cost or improve the performance, durability, or efficiency of fuel cells or hydrogen fuel production. For example, in contrast to industry’s primary focus, which is polymer electrolyte membrane fuel cells (PEMFC), selected projects include a higher risk, completely different approach—alkaline exchange membrane fuel cells (AEMFC)—that can significantly reduce or even eliminate the need for expensive platinum as a catalyst in the long term. Such high-risk but high-impact potential projects complement the current FCTO portfolio.
Update on the GM-Honda collaboration on Gen 2 Fuel Cell Propulsion System
February 17, 2015
|Overview and partitioning of the GM-Honda collaboration on fuel cell propulsion. Click to enlarge.|
Over the past two years, GM and Honda have been collaborating on next-generation fuel cell and hydrogen storage systems, aiming at commercialization in the 2020 time frame. (Earlier post.) At the SAE 2015 Hybrid & Electric Vehicle Technologies Symposium in Los Angeles last week, Andrew Bosco, Chief Engineer for fuel cell engineering at GM, provided an progress update on the joint Gen 2 Fuel Cell Propulsion System. (At the SAE 2014 Hybrid & Electric Vehicle Technologies Symposium, Mark Mathias, Director, Fuel Cell R&D for GM, had also provided an update on the collaboration. Earlier post.)
As the two companies have emphasized from the beginning, Bosco reinforced that the current scope of the collaboration focuses on reducing the high cost of fuel cell specific systems: i.e., the fuel cell stack; balance of plant components; and hydrogen storage system (HSS). Development on the battery (regenerative ESS), fuel cell power electronics (FCPE); and electric traction system (ETS) is leveraging know-how and components from hybrids and battery-electric vehicle work.
