One of the fantastic things about batteries is regenerative braking. Hard to imagine how you do that with H2 and no battery side storage.

S. Korean team develops highly efficient, long-lasting electrocatalyst to boost electrolytic hydrogen production
Conventional water electrolysis for the production of hydrogen faces technological challenges to improve the efficiency of the water-splitting reaction for the sluggish oxygen evolution reaction (OER). Noble metal-based ruthenium oxide (RuO2) and iridium oxide (IrO2) are used to enhance the oxyg...
Paroway. OK. Adjust on two accounts, I see they were Aust $, which is $0.71 US. Second, take $0.10/KWh electricity since I referred to EPA CO2 in delivered electricity. So about a 10% increase in electricity cost.

Santos reports successful CO2 capture and storage injection trial in Moomba CCS project
Australia-based natural gas company Santos has successfully injected approximately 100 tonnes of carbon dioxide deep underground into depleted gas reservoirs as part of the final field trial for the Moomba Carbon Capture and Storage (CCS) Project. Santos Managing Director and CEO Kevin Gallag...
At $30/tonne and 7.07E-4 metric ton CO2/kWh (EPA average electricity, delivered) that comes to about 2.1 cents per KWh for carbon charge or an ~50% increase in the price of current electricity.

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, whi...

Interesting study. Actual result is that marijuana increased the crash rate (relative risk) by 1.25-fold, but that this was insignificant when age, gender ethnicity and alcohol use were brought into play. The 1.25-fold rate, incidentally, is about that of the risk factor for blood-alcohol of 0.03 (well below the level of 0.08 where most states consider this a DUI, and at which point the relative risk is 3.98-fold increased).

NHTSA releases two new studies on impaired driving on US roads; drunk driving down, drug use up
The nation’s decades-long campaign to combat drunk driving continues to make roads safer, but use of marijuana and prescription drugs is increasingly prominent on the highways, creating new safety questions, according to a pair of new studies released by the Department of Transportation’s Nation...

JBEI researchers engineer bacterium to produce diesel-range biofuel using CO2 as sole carbon source
A team of researchers with the US Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI) has engineered the bacterium Ralstonia eutropha—a microbe now used to produce biodegradable plastic—for the production of fatty acid-derived, diesel-range methyl ketones. A paper on their work is publ...
A wash is right. The CO2 is captured as a by-product of refinery operations, later to be burnt as fuel. There is no carbon capture here.

General question: A person buys a Leaf in 2013, five years later there are better batteries. Presumably the new batteries would have different volts/amps. Anyone have a feel for how the current car would fit in with the new battery designs. Would there be a fix for switching to the new batteries?

Australia in the midst of a drought that is popularly thought to be CO2-related. Here they are pulling more carbon out of the ground and burning it with some deference to CO2 entrapment. Rediculous back-pedaling.
