UK, Saudi team shows hydrocarbon wax is a viable, safe medium for on-board hydrogen storage
October 20, 2016
Researchers at the universities of Oxford, Cambridge and Cardiff in the UK, and the King Abdulaziz City for Science and Technology (KACST) in Saudi Arabia have shown that benign, readily-available heavy alkane hydrocarbon wax is capable of rapidly releasing large amounts of hydrogen—sufficient to meet the 7 wt% target set by the US DOE—through microwave-assisted catalytic decomposition.
This discovery, reported in an open-access paper in Scientific Reports, offers a new material and system for safe and efficient hydrogen storage and could facilitate its application in a hydrogen fuel cell vehicle. Hydrocarbon wax is the major product of the low temperature Fischer-Tropsch synthesis process from syngas and is currently thermally “cracked” to produce various fuels.

DOE to invest $30M to further H2 and fuel cell technology as industry continues strong growth
The US Department of Energy (DOE) Energy Department (DOE) released a new report showing continued momentum and growth in the fuel cell industry. The 2015 Fuel Cell Technologies Market Report shows that more than 60,000 fuel cells, totaling roughly 300 megawatts (MW), shipped worldwide in 2015. The number of MW shipped grew by more than 65% compared to 2014. 2015 also saw the world’s first fuel cell vehicles for sale.
To further this emerging market, DOE also announced a notice of intent (DE-FOA-0001411) to invest $30 million, subject to appropriations, to advance fuel cell and hydrogen technologies. These projects will leverage national lab consortia launched under DOE’s Energy Materials Network (EMN) this past year (earlier post), and will support the President’s Materials Genome Initiative and advanced manufacturing priorities.
Researchers discover lower-cost, energy-efficient way to produce alane for hydrogen storage
September 23, 2016
Scientists at the US Department of Energy’s Ames Laboratory, in collaboration with partners from Iowa State University, University of Illinois Urbana-Champaign, University of Wisconsin-Madison, and University of Pittsburgh, have discovered a less-expensive, more energy-efficient way to produce alane—aluminum trihydride (AlH3)—a high-capacity hydrogen source that had widely been considered to be a technological dead-end for use in automotive vehicles.
Although attractive for its high intrinsic capacity (10.1 wt% H2), small heat of formation (∼7 kJ/mol H2), and fast apparent decomposition kinetics, regeneration of spent Al by direct hydrogenation has been impractical due to the extremely high hydrogen equilibrium pressure required (∼7000 bar).
DOE seeking input on H2@scale: hydrogen as centerpiece of future energy system; 50% reduction in energy GHGs by 2050
September 11, 2016
Earlier this year, The US Department of Energy (DOE) national laboratories identified the potential of hydrogen to decarbonize deeply a multitude of sectors in a proposal termed “H2@Scale”.

USC team develops new robust iridium catalyst for release of hydrogen from formic acid
June 17, 2016
A team of researchers at the University of Southern California has developed a robust, reusable iridium catalyst that enables hydrogen gas release from neat formic acid. The catalyst works under mild conditions in the presence of air, is highly selective and affords millions of turnover numbers (TONs).
Although other catalysts exist for both formic acid dehydrogenation and carbon dioxide reduction, solutions to date on hydrogen gas release rely on volatile components that reduce the weight content of stored hydrogen and/or introduce fuel cell poisons; this new catalyst does not. An open-access paper on their work is published in the journal Nature Communications.

Japanese public-private partnership to test end-to-end H2 supply chain using wind power to begin this fall; 2nd-life hybrid batteries for ESS
March 14, 2016
A Japanese partnership comprising the Kanagawa Prefectural Government; the municipal governments of the cities of Yokohama and Kawasaki; Toyota; Toshiba; and Iwatani announced the forthcoming start of a four-year project to implement and evaluate an end-to-end low-carbon hydrogen supply chain which will use hydrogen produced from renewable energy to power forklifts. (Earlier post.) The project will be carried out at facilities along Tokyo Bay in Yokohama and Kawasaki, with support from Japan’s Ministry of the Environment.
Electricity generated at the Yokohama City Wind Power Plant (Hama Wing) will power the electrolytic production of hydrogen, which will then be compressed, stored, and then transported in a hydrogen fueling truck to four sites: a factory, a vegetable and fruit market, and two warehouses. At these locations, the hydrogen will be used in fuel cells to power forklifts operating in diverse conditions.

Kawasaki is also currently developing a small test vessel for the marine transportation of liquefied hydrogen. (Earlier post.) The vessel will have a cargo capacity of 2,500 m3, equivalent to that of coastal trading LNG vessels.
Berkeley Lab team develops new high-performance solid-state H2 storage material: graphene oxide (GO)/Mg nanocrystal hybrid
March 12, 2016
Researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a new, environmentally stable solid-state hydrogen storage material constructed of Mg nanocrystals encapsulated by atomically thin and gas-selective reduced graphene oxide (rGO) sheets.
This material, protected from oxygen and moisture by the rGO layers, exhibits dense hydrogen storage (6.5 wt% and 0.105 kg H2 per liter in the total composite). As rGO is atomically thin, this approach minimizes inactive mass in the composite, while also providing a kinetic enhancement to hydrogen sorption performance.
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.
