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.

Univ. Houston, Caltech team develops new earth-abundant, cost-effective catalyst for water-splitting

September 20, 2016

A team of researchers from the University of Houston and the California Institute of Technology has developed an active and durable earth-abundant transition metal dichalcogenide-based hybrid catalyst for water-splitting that exhibits high hydrogen evolution activity approaching the state-of-the-art platinum catalysts. The new catalyst also offers activity superior to that of most transition metal dichalcogenides (molybdenum sulfide, cobalt diselenide and so on).

The material is fabricated by growing ternary molybdenum sulfoselenide particles on self-standing porous nickel diselenide foam. In an open-access paper in the journal Nature Communications, the team said that their advance provides a different pathway to design cheap, efficient and sizable hydrogen-evolving electrode by simultaneously tuning the number of catalytic edge sites, porosity, heteroatom doping and electrical conductivity.

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”. Preliminary analysis performed by the national laboratories on the H2@Scale concept indicated that nearly a 50% reduction in greenhouse gas emissions is possible by 2050 via such large-scale hydrogen production and use.

The concept sees hydrogen—a flexible, clean energy-carrying intermediate—having the potential to be a centerpiece of a future energy system where aggressive market penetration of renewables (wind and solar) are coupled with renewable hydrogen production to meet society’s energy demands across industrial, transportation, and power generation sectors using clean, renewable resources and processes.

SLAC, Stanford team develops new catalyst for water-splitting for renewable fuels production; 100x more efficient than other acid-stable catalysts

September 02, 2016

Researchers at Stanford University and the Department of Energy’s SLAC National Accelerator Laboratory have developed a new highly active and stable IrOx/SrIrO3 catalyst for the oxygen evolution reaction (OER).

The new catalyst outperforms known IrOx and ruthenium oxide (RuOx) systems, the only other OER catalysts that have reasonable activity in acidic electrolyte. Because it requires less of the rare and costly metal iridium, the new catalyst could bring down the cost of artifical photosynthetic processes that use sunlight to split water molecules—a key step in a renewable, sustainable pathway to produce hydrogen or carbon-based fuels that can power a broad range of energy technologies. The team published their results in the journal Science.

Researchers identify pentlandite as equally efficient alternative to platinum for hydrogen production

July 27, 2016

Researchers have identified artificially-produced pentlandite (a natural ore, Fe4.5Ni4.5S8) as a direct ‘rock’ electrode without the need of further surface modifications for hydrogen evolution under acidic conditions. The pentlandite provides high activity and stability at low overpotential for H2 generation. According to their study, artificial pentlandite is just as efficient as the platinum electrodes commonly used today for the electrolytic production of hydrogen from water, but is lower cost.

A team headed by Dr. Ulf-Peter Apfel and Prof. Dr. Wolfgang Schuhmann of the Ruhr-Universität Bochum describes the results of their work together with colleagues from the Max-Planck-Institute for Coal Research in Mülheim an der Ruhr and the Technical University of Bratislava in an open-access paper published in Nature Communications.

UK team produces hydrogen from fescue grass via photocatalytic reforming

July 21, 2016

A team of researchers from the UK’s Cardiff University’s Cardiff Catalysis Institute and Queen’s University Belfast have shown that significant amounts of hydrogen can be unlocked from fescue grass—without significant pre-treatment—using sunlight and a metal-loaded titania photocatalyst. An open access paper on their work is published in Proceedings of the Royal Society A.

Based on their study, the team proposed that the first step in their photoreforming of cellulose was the (photo)hydrolysis of cellulose into glucose, with the latter then undergoing reforming to hydrogen and CO2. It is the first time that this method has been demonstrated and could potentially lead to a sustainable way of producing hydrogen.

Duke study: serpentinized rock in oceans may be large, overlooked source of free hydrogen gas

Rocks formed beneath the ocean floor by fast-spreading tectonic plates may be a large and previously overlooked source of free hydrogen gas, a new Duke University study suggests. Their paper is published in the journal Geophysical Research Letters.

Recent discoveries of free hydrogen gas, which was once thought to be very rare, have been made near slow-spreading tectonic plates deep beneath Earth’s continents and under the sea. Previous estimates suggest that serpentinization—a processes whereby rock is changed, with the addition of water, into the crystal structure of the minerals found within the rock—within the continental lithosphere (the crust and upper mantle of the earth) produces hydrogen at rates comparable to the oceanic lithosphere (both are ~1011 mol H2/yr).

DOE awards $14M to advance hydrogen fuel technologies

July 12, 2016

The US Department of Energy (DOE) announced up to $14 million in funding for the advancement of hydrogen fuel technologies. Specifically, these selections include advanced high-temperature water splitting; advanced compression; and thermal insulation technologies.

For cost-competitive transportation, hydrogen must be comparable to conventional fuels and technologies on a per-mile basis in order to succeed in the commercial marketplace. DOE’s current target is to reduce the cost of producing and delivering hydrogen to less than $4 per gallon of gas equivalent (gge) by 2020 and $7/gge for early markets.

KTH team develops new cost-effective water-splitting electrocatalyst for H2 production

June 27, 2016

Researchers at KTH Royal Institute of Technology in Stockholm have developed a new cost-effective electrocatalyst for water-splitting to produce hydrogen.

The monolayer of nickel–vanadium-layered double hydroxide shows a current density of 27 mA cm−2 (57 mA cm−2 after ohmic-drop correction) at an overpotential of 350 mV for water oxidation. This performance is comparable to those of the best-performing electrocatalysts that are composed of non-precious materials—nickel–iron-layered double hydroxides for water oxidation in alkaline media—the researchers report in an open access paper in Nature Communications.

Stanford solar tandem cell shows promise for efficient solar-driven water-splitting to produce hydrogen

June 23, 2016

Researchers at Stanford University, with colleagues in China, have developed a tandem solar cell consisting of an approximately 700-nm-thick nanoporous Mo-doped bismuth vanadate (BiVO4) (Mo:BiVO4) layer on an engineered Si nanocone substrate. The nanocone/Mo:BiVO4 assembly is in turn combined with a solar cell made of perovskite.

When placed in water, the device immediately began splitting water at a solar-to-hydrogen conversion efficiency of 6.2%—matching the theoretical maximum rate for a bismuth vanadate cell. Although the efficiency demonstrated was only 6.2%, the tandem device has room for significant improvement in the future, said Stanford Professor Yi Cui, a principal investigator at the Stanford Institute for Materials and Energy Sciences and senior author of an open access paper describing the work published in Scientific Advances.

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.

Researchers report cost-effective synthesis of NiFe-layered double hydroxides nanosheets as efficient OER catalyst

May 31, 2016

A team from Brown University and Lakehead University (Canada) have developed a method for the facile and cost-effective synthesis of NiFe-layered double hydroxides (LDH) nanosheets to serve as efficient catalyst for the oxygen evolution reaction in an alkaline environment.

Compared to previously reported LDH catalysts, the new nanosheets exhibit a much higher oxygen evolution activity. The overpotential of catalytic OER was very low and the Tafel slope (Tafel analysis is a tool for comparing electrocatalytic activity and elucidating the reaction mechanism) was close to that of a commercial RuO2 catalyst. A paper describing their work is published in the journal Electrochemistry Communications.

SLAC, U Toronto team develops new highly efficient ternary OER catalyst for water-splitting using earth-abundant metals; >3x TOF prior record-holder

March 25, 2016

Scientists from the Department of Energy’s SLAC National Accelerator Laboratory and the University of Toronto have developed a new type of ternary catalyst for the oxygen evolution reaction (OER) in water-splitting that exhibits a turnover frequency (TOF) that’s more than three-times above the TOF and mass activities of optimized control catalysts and the state-of-art NiFeOOH catalyst.

The research, published in the journal Science, outlines a potential way to make a future generation of water-splitting catalysts from three abundant metals—iron (Fe), cobalt (Co) and tungsten (W)—rather than the rare, costly metals on which many of today’s catalysts rely. The gelled FeCoW oxy-hydroxide material exhibits the lowest overpotential (191 mV) reported at 10 mA per square centimeter in alkaline electrolyte. Further, the ternary catalyst showed no evidence of degradation following more than 500 hours of operation.

German team doubles activity of water electrolysis catalysts for H2 production with monolayer of copper on platinum

March 10, 2016

A team from the Ruhr-Universität Bochum, Technische Universität München and Universiteit Leiden has doubled the catalytic activity of electrodes for water electrolysis by applying a monolayer of copper the platinum electrodes. The resulting electrodes are the most active electrocatalysts ever reported for the HER (hydrogen evolution reaction) in acidic media under comparable conditions, to the best of their knowledge, wrote the authors in an open-access paper in the journal Nature Communications.

Only about 4% of global hydrogen production is via water electrolysis, according to a 2012 analysis (Bičáková and Straka). The main impediments to a wider commercialization are the high energy losses in electrolyzers due to the insufficient activity of state-of-the-art electrodes.

Berkeley team develops host-guest nanowires for efficient water splitting and solar energy storage

February 04, 2016

Although metal oxides that absorb visible light are attractive for use as photoanodes in photoelectrosynthetic cells, their performance is often limited by poor charge carrier transport. Researchers from UC Berkeley and colleagues have now addressed this issue by using separate materials for light absorption and carrier transport.

The team reports on their host-guest system of Ta:TiO2|BiVO4 as a photoanode for use in solar water splitting cells in an open-access paper in the journal ACS Central Science. BiVO4 acts as a visible light-absorber and Ta:TiO2 acts as a high surface area electron conductor. The host–guest nanowire architecture allows for simultaneously high light absorption and carrier collection efficiency for efficient solar water oxidation.

New German ecoPtG project seeks to make power-to-gas commercially viable with help of automotive technology

In collaboration with engineering partner IAV, the Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg (Centre for Solar Energy and Hydrogen Research Baden-Württemberg, ZSW); the Reiner Lemoine Institut (RLI); and Wasserelektrolyse Hydrotechnik (HT) are researching cost-effective methods of producing hydrogen with the help of automotive technology. In the ecoPtG project, the researchers and engineers are developing an alkaline water electrolyzer with an output of 100 kW. They aim to demonstrate that CO2-neutral hydrogen can be produced in a cost-effective manner and intend to facilitate the storage of electricity.

Electricity is increasingly being generated from fluctuating renewable sources. Solar and wind energy generation depends on the weather and is subject to significant fluctuations. At times, renewable energy production thus temporarily exceeds regional demand. Hydrogen produced according to the power-to-gas method can play a role in resolving this challenge and decarbonizing the transport sector. By converting electricity to gas, solar and wind power become storable. If required, hydrogen can be reconverted or used as environmentally compatible fuel for fuel cell vehicles.

FuelCell Energy pathway for hydrogen from digester gas has negative carbon intensity for CA LCFS

December 23, 2015

Connecticut-based FuelCell Energy (FCE) has applied for a prospective pathway for California’s Low Carbon Fuel Standard (LCFS) for the production of hydrogen fuel produced from biogas derived from the mesophilic anaerobic digestion of wastewater sludge at a publicly owned treatment works (POTW).

The biogas is cleaned, then internally reformed in an integrated hydrogen energy system (Tri-Gen DFC) that produces hydrogen fuel for transportation; electric power for plant operations and export; as well as thermal energy for plant use. Once the internal energy demands of the pathway have been met, any energy not utilized for process is considered to be surplus to the system boundary and is credited to the FCE pathway.

NREL research advances photoelectrochemical production of hydrogen using molecular catalyst

December 21, 2015

Researchers at the Energy Department’s National Renewable Energy Laboratory (NREL) have made advances toward affordable photoelectrochemical (PEC) production of hydrogen. A paper on their work is published in Nature Materials.

The PEC process uses solar energy to split water into hydrogen and oxygen. The process requires special semiconductors, the PEC materials and catalysts to split the water. Previous work used precious metals such as platinum, ruthenium and iridium as catalysts attached to the semiconductors. A large-scale commercial effort using those precious metals wouldn’t be cost-effective, however.

Proof-of-principle of cost-effective methane cracking technology for H2 production without CO2; 50% cleaner than SMR, comparable to electrolysis

November 19, 2015

Researchers of the Institute for Advanced Sustainability Studies (IASS) in Potsdam and the Karlsruhe Institute of Technology (KIT) have achieved the proof-of-principle for a innovative technique to extract hydrogen (H2) from methane (CH4) without the formation of CO2 as a byproduct.

At this stage, cost estimates are uncertain, since methane cracking is not yet a fully mature technology. However, preliminary calculations show that it could achieve costs of €1.9 to €3.3 per kilogram of hydrogen at German natural gas prices—without taking the market value of the solid black carbon byproduct of the process into consideration.

AC Transit files LCFS pathway application for H2 produced by electrolysis (solar): 0.00 gCO2e/MJ

November 06, 2015

AC Transit (Alameda-Contra Costa Transit District), which operates the third-largest public bus system in California, has filed a fuel pathway application for gaseous hydrogen produced via electrolysis powered by renewable electricity (solar) with the California Air Resources Board (ARB) under the Low Carbon Fuel Standard (LCFS) regulation.

According to AC Transit’s analysis—which is supported by ARB Staff—the carbon intensity (CI) of the gaseous hydrogen produced by the pathway is 0.00 gCO2e/MJ—i.e., a zero-carbon fuel on a “well-to-tank” lifecycle basis.
