Australia Goes All-in on Green Hydrogen

Cars That Think

They’ve been studying up on renewable energy, hydrogen power, and electric vehicles, preparing for the big day in April when their remote-controlled vehicles will rumble for 4 hours in Gladstone, a port city in Queensland. And while coal plants still supplied over half of Australia’s power in 2021, change is afoot.

CMU study finds controlled EV charging can reduce generation cost, but at greater health and environmental costs depending upon the generation mix

Green Car Congress

Results from the study also suggest that with sufficient coal plant retirement and sufficient wind power, controlled charging could result in positive net benefits instead of negative. Reduction in annual generation cost and external emissions costs due to controlled charging compared to uncontrolled charging ($2010).

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

Specifically, to minimize GHG emissions and total energy use, is it better to use natural gas in a stationary power application to generate electricity to charge EVs, to compress natural gas for onboard combustion in vehicles, or to reform natural gas into a denser transportation fuel? Right: WTW greenhouse gas emissions.

Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

As the percentage of electricity supply from wind and solar increases, grid operators will need to employ strategies and technologies, including energy storage, to balance supply with demand given the intermittency of the renewable supply. The Stanford study considered a future US grid where up to 80% of the electricity comes from renewables.

EIA Energy Outlook 2013 reference case sees drop in fossil fuel consumption as use of petroleum-based liquid fuels falls; projects 20% higher sales of hybrids and PHEVs than AEO2012

Green Car Congress

Sales of battery-powered electric vehicles are 65% lower in the AEO2013 Reference case than the year before, with annual sales in 2035 estimated to be about 119,000. Reductions in battery electric vehicles are offset by increased sales of hybrid and plug-in hybrid vehicles, which grow to about 1.3 than in AEO2012.
