The researchers found that while EVs do offer a very promising solution to energy issues due to their replacement of petroleum fuels, for now “ the high pollution levels of coal-fired power plants will trade off EVs’ potential energy benefits in China ”. The power of EVs is electricity from the grid. Click to enlarge.
For those who care about the environment and keeping their driving footprint small, one of the most compelling selling points for electric cars is that your car gets cleaner over time—because the electricity you’re plugging into, from the powergrid, is being weaned off coal and toward cleaner and more sustainable sources.
To achieve the best outcomes, the brief suggests, plug-in vehicle adoption should typically be focused on HEVs and PHEVs by city drivers in mild-climate regions with a clean electricity grid, such as San Francisco or Los Angeles. Further, drivers should not be encouraged to charge at night in coal-heavy regions.
Developing technologies for the conversion of biomass and coal-to-liquid fuels. By 2035, cellulosic ethanol and/or coal-and-biomass-to-liquid (CBTL) fuels with carbon capture and storage could replace about 15% of current fuel consumption in the transportation sector (1.7–2.5 the powergrid) are urgently needed.
In a new study published in the journal Applied Energy , Carnegie Mellon University (CMU) researchers found that controlled charging of plug-in hybrid electric vehicles (PHEVs) reduces the costs of integrating the vehicles into an electricity system by 54–73% depending on the scenario. Weis et al. Click to enlarge.
Methanol-powered vehicles are one pillar of Geely Auto’s diversified new-energy strategy, which also encompasses ethanol, CNG, gasoline-electric hybrid, plug-in hybrid, pure-electric, and extended-range solutions. cited one study showing that the full lifecycle (well-to-wheel) CO 2 emissions from M85 (with coal-derived methanol) are 2.5
As automakers develop more efficient electric motors, EVs pulling electrons from dirtier, coal-poweredgrids are as clean or cleaner than even the most efficient fossil-fueled cars when it comes to equivalent tailpipe emissions. But electric vehicles still have a supply-chain problem.
In this topic, ARPA-E seeks to develop a new generation of ultra-high energy density, low-cost battery technologies for long electric range plug in hybrid electric vehicles and electric vehicles (EVs). Grid-Scale Rampable Intermittent Dispatchable Storage (GRIDS).
It’s all part of the Obama administration’s plan get to 1 million plug in hybrids on the road by 2015. “Even as our economy has been transformed by new forms of technology, our electric grid looks largely the same as it did half a century ago,&# Obama said. billion competitive grant program for US battery makers.
At Consumer Electronics Show Asia, Ford launched a strategic collaboration with Haier (home appliance), Trina Solar (solar power) and Delta Electronics (power management) to introduce MyEnergi Lifestyle ( earlier post ) to China, a holistic approach for lowering the energy costs and carbon footprint of Chinese families.
Mileage from Megawatts: Study finds enough electric capacity to "fill up" plug-in vehicles across much of the nation RICHLAND, Wash. – Lightner noted that "the study suggests the idle capacity of the electric powergrid is an underutilized national asset that could be tapped to vastly reduce our dependence on foreign oil."
The study estimates that global sales of plug-in vehicle will likely constitute 10% of new vehicle sales by 2020. The full set of such standards should not only govern the physical interface, but also take into consideration safety and powergrid standards. The first emerging standard is for vehicle charging.
For instance, electricity generated from coal or natural gas is associated with higher carbon emissions, while renewable sources like wind or solar energy contribute negligible carbon pollution. As more renewable energy sources are integrated into the powergrid, the overall greenhouse gas emissions associated with EVs can be further reduced.

And while coal plants still supplied over half of Australia’s power in 2021, change is afoot. The 124-megawatt solar plant adjacent to Korea Zinc’s Townsville refinery, completed in 2018, cut a quarter of the coal-heavy gridpower it had been using to run its power-intensive electrolytic process.
Studies have found that even cars charged on dirty, coal-poweredgrids have overall emissions no higher than a very fuel-efficient internal-combustion car. With no tailpipe emissions, electric cars have a clear advantage over their gasoline and diesel counterparts when it comes to carbon emissions.
ChargePoint’s stance is bolstered by a new MIT study that suggests , in part, that electric cars that plug into the grid, could, collectively, act as a massive “virtual battery” for grid energy storage. In the powergrid, supply and demand need to match exactly. ChargePoint envisions that at scale—i.e.,
Australian EV charging infrastructure company JET Charge has joined a study to establish technology for discharging power from EVs into Australia’s national powergrid. In Canberra, 16 of the REVS EVs that were plugged in responded by rapidly discharging short bursts of electricity into the grid.
The 260-kilometer, 320-kilovolt high-voltage direct-current (HVDC) transmission system, based on technology from Hitachi Energy , in Zurich, marks a milestone in an ongoing transformation of the European powergrid: It will plug into the first truly dynamic multiterminal HVDC network in Europe.

Now, people are used to cellphone subscription plans and plugging the phone into the wall at night, Mr. Thesen reasoned, so a switch to electric cars would also be manageable. Rather than setting up the public for disappointment (see ethanol), plug-n electric advocates should push the very real, if not sexy, advantages. — DonO 5.
Vehicle to Grid is a really interesting area to do projects. The idea here is that you can connect your EV to the powergrid and flow power from your EV to the Grid. An electric car acts as a load or micro-generating station for the grid. Advantages of V2G in grid perspective 2. can be done. #62
One of the biggest challenges to the nations powergrid "is going to be the introduction of electric vehicles," said Dana Christiansen, associate director of the Oak Ridge National Laboratory, which has partnered with Nissan, TVA and the state of Tennessee to help develop the charging infrastructure to support the vehicles.

Dont PHEVs just shift pollution from gasoline cars to power plants? But its monumentally less pollution , even on the national (half-coal) grid.
That need for balance is true of electric powergrids, too. Spiking demand for electric heat collided with supply problems created by frozen natural-gas equipment and below-average wind-power production. Packetized energy management (PEM) allows the powergrid to flexibly handle a varying supply of renewable energy.
Jenkins has also helped push Congress to think more seriously about the powergrid, releasing a report last year that showed that much of the 43 percent emissions reduction expected by 2030 would be squandered if the United States doesn’t double the pace of transmission upgrades. power-grid transmission.
Wires have a lot going for them when it comes to moving electric power around, but they have their drawbacks too. Who, after all, hasn’t tired of having to plug in and unplug their phone and other rechargeable gizmos? It’s a nuisance. Can the same basic physics be harnessed to replace wires today?
It’s very similar to the infrastructure for electric cars because the idea, ultimately, for electric cars is that you also are revamping your grid to facilitate, whatchamacallit, intermittent renewable energy sources, like wind and solar, because having an electric car that runs off a coal-fired power plant is defeating the purpose, essentially.
