GWU team demonstrates one-pot process for optimized synthesis of controlled CNTs from CO2; coupling cement and C2CNT

27 March 2017

Researchers at George Washington University led by Dr. Stuart Licht (earlier post) have developed a new process that transforms CO2 into a controlled selection of nanotubes (CNTs) via molten electrolysis; they call the process C2CNT (CO2 into carbon nanotubes). This synthesis consumes only CO2 and electricity, and is constrained only by the cost of electricity.

Controlling the electrolysis parameters opens up a wide portfolio of CNT morphologies, including hollow or solid, thick- or thin-walled and doped CNTs. Molten carbonate electrosynthesized boron-doped CNTs exhibit high electrical conductivity. The process is described in a paper published in the Journal of CO2 Utilization. In a second paper in that journal, the team reports on the uses of C2CNT to retrofit cement plants. Per ton CO2 avoided, the C2CNT cement plant consumes $50 electricity, emits no CO2, and produces $100 cement and ∼$60,000 of CNTs.

EIA: US energy-related CO2 dropped 2.7% in 2015; of end-use sectors, only transportation increased

27 March 2017

According to a report from the US Energy Information Administration (EIA), US energy-related CO2 emissions decreased by 146 million metric tons (MMmt) in 2015 to 5,259 MMmt, down 2.7% from 5,405 MMmt in 2014. This decline occurred despite growth in real gross domestic product (GDP) of 2.6% as other factors more than offset the growth in GDP. Energy-related CO2 emissions in 2015 were about 12% below 2005 levels.

These factors included a decline in the carbon intensity of the energy supply (CO2/British thermal units [Btu]) of 1.8%; and a 3.4% decline in energy intensity (Btu/GDP). Of the four end-use sectors, only transportation emissions increased in 2015 (+2.1%).

Aalto University team develops promising new electrocatalyst for hydrogen evolution reaction; one-hundredth the amount of Pt

26 March 2017

A group of Aalto University (Finland) researchers led by professors Tanja Kallio and Kari Laasonen has developed a manufacturing method for hydrogen evolution reaction (HER) electrocatalysts that use only one-hundredth of the amount of platinum generally used in commercial products.

They achieved pseudo atomic-scale dispersion of Pt—i.e. individual atoms or sub-nanometer clusters—on the sidewalls of single-walled carbon nanotubes (SWNTs) with a simple and readily up-scalable electroplating deposition method. These SWNTs activated with an ultra-low amount of Pt exhibit a similar activity to that of a commercial Pt/C with a notable higher (~66-333 fold) Pt loading for catalyzing hydrogen evolution reaction (HER) under the acidic conditions required in proton exchange membrane technology. A paper on their work is published in the journal ACS Catalysis.

California ARB votes to move forward with light-duty vehicle GHG and ZEV programs through 2025; cranking it up post-2025

25 March 2017

After considering the Advanced Clean Cars Midterm Review (earlier post), the California Air Resources Board voted unanimously on Friday to continue with the vehicle greenhouse gas emission standards and ZEV program for cars and light trucks sold in California through 2025. The action ensures that California and 12 other states that follow its vehicle regulations—one third of the US auto market—will move forward the greenhouse gas emission standards adopted in the 2012 process involving the federal government, California and the automakers.

The Board also voted to support the expansion of the ZEV marketplace before 2025, calling for redoubling current efforts underway to support market growth and paving the way for new regulations to increase rapidly the number of zero-emission vehicles required to be sold in California after 2025.

US State Department issues Presidential Permit to TransCanada for Keystone XL

24 March 2017

The US Department of State has signed and issued a Presidential Permit to construct the Keystone XL Pipeline. The permit authorizes TransCanada to construct, to connect, to operate, and to maintain pipeline facilities at the US-Canadian border in Phillips County, Montana for the importation of crude oil.

In November 2016, then US Secretary of State John Kerry had rejected the controversial Keystone XL, citing combatting climate change as the critical factor. Kerry noted at that time that the arguments pro and con had been “overstated”. (Earlier post.) In January 2017, two days after newly inaugurated President Trump issued a Presidential Memorandum inviting TransCanada to “promptly re-submit its application to the Department of State for a Presidential permit for the construction and operation of the Keystone XL Pipeline,” the company did so.

California ARB moves forward with climate and air quality actions

24 March 2017

On the first day of a two-day board meeting—the second day of which (Friday 24 March) will consider the Advanced Clean Cars Midterm Review—the California Air Resources Board (ARB) took a number of climate and air quality actions. CARB approved the State Strategy for the State Implementation Plan (State SIP Strategy), which describes CARB’s commitment for further reducing vehicle emissions needed to meet federal air quality standards over the next 15 years. The Board also approved the South Coast Air Quality Management District’s comprehensive air quality plan.

CARB also adopted a new plan to curb destructive “super pollutants” including black carbon, fluorinated gases and methane. The plan, California’s Short-lived Climate Pollutant Reduction Strategy, maps out the route to more rapid greenhouse gas reductions by clamping down on these super pollutants.

Researchers create efficient, simple-to-manufacture photoanode for solar water-splitting

24 March 2017

Researchers at Rice University and the University of Houston created an efficient, simple-to-manufacture core/shell photoanode with a highly active oxygen evolution electrocatalyst shell (FeMnP) and semiconductor core (rutile TiO2) for the photoelectrochemical oxygen evolution reaction (PEC-OER) for solar water splitting.

The lab of Kenton Whitmire, a Rice professor of chemistry, teamed up with researchers at the University of Houston and discovered that growing a layer of an active catalyst directly on the surface of a light-absorbing nanorod array produced an artificial photosynthesis material that could split water at the full theoretical potential of the light-absorbing semiconductor with sunlight. The results appear in two new studies. The first, on the creation of the catalytic films, appears in Chemistry: A European Journal. The second, which details the creation of photoanodes, appears in ACS Nano.

Yale team develops dendrimer-graphene oxide composite film for improved cycling of Li-sulfur batteries

23 March 2017

Researchers at Yale University developed an ultrathin functionalized dendrimer–graphene oxide composite film that can be applied to virtually any sulfur cathode in a Li-sulfur (Li-S) battery system to alleviate capacity fading over battery cycling without compromising the energy or power density of the entire battery.

Sulfur electrodes coated with the composite film exhibit very good cycling stability, together with high sulfur content, large areal capacity, and improved power rate. The film design provides a new strategy for confining lithium polysulfides. A paper on their work is published in Proceedings of the National Academy of Sciences (PNAS).
