Some Electric Car Drivers Might Spew More CO2 Than Diesel Cars, New Research Shows (bloomberg.com)

bricko shares a report from Bloomberg with the caption, "Making batteries is a mess": Beneath the hoods of millions of the clean electric cars rolling onto the world's roads in the next few years will be a dirty battery. Every major carmaker has plans for electric vehicles to cut greenhouse gas emissions, yet their manufacturers are, by and large, making lithium-ion batteries in places with some of the most polluting grids in the world. By 2021, capacity will exist to build batteries for more than 10 million cars running on 60 kilowatt-hour packs, according to data of Bloomberg NEF. Most supply will come from places like China, Thailand, Germany and Poland that rely on non-renewable sources like coal for electricity.

An electric vehicle in Germany would take more than 10 years to break even with an efficient combustion engine's emissions. "We're facing a bow wave of additional CO2 emissions," said Andreas Radics, a managing partner at Munich-based automotive consultancy Berylls Strategy Advisors, which argues that for now, drivers in Germany or Poland may still be better off with an efficient diesel engine. The findings, among the more bearish ones around, show that while electric cars are emission-free on the road, they still discharge a lot of the carbon-dioxide that conventional cars do. Just to build each car battery -- weighing upwards of 500 kilograms (1,100 pounds) in size for sport-utility vehicles -- would emit up to 74 percent more C02 than producing an efficient conventional car if it's made in a factory powered by fossil fuels in a place like Germany, according to Berylls' findings. Yet regulators haven't set out clear guidelines on acceptable carbon emissions over the life cycle of electric cars, even as the likes of China, France and the U.K. move toward outright bans of combustion engines.
It all has to do with manufacturing. According to estimates of Mercedes-Benz's electric-drive system integration department, manufacturing an electric car pumps out "significantly" more climate-warming gases than a conventional car, which releases only 20 percent of its lifetime CO2 at this stage. "Just switching to renewable energy for manufacturing would slash emissions by 65 percent, according to Transport & Environment," reports Bloomberg. "In Norway, where hydro-electric energy powers practically the entire grid, the Berylls study showed electric cars generate nearly 60 percent less CO2 over their lifetime, compared with even the most efficient fuel-powered vehicles."

    This doesn't seem to take into account that many grids are rapidly improving in terms of how much solar and wind they have in the grids. If an electric car hits breakeven compared to a highly efficient diesel car given 5 years given current rates for example, then in practice we should expect that to happen even earlier. Moreover, electric cars have very long potential lifespans since they contain few moving parts (there's correspondingly less maintenance on an electric car than on an ICE car). Of course, the most efficient thing to do is still to not have a car, and use public transport; unfortunately for many people that isn't a practical option.

No one says "OMG REPLACING MY ENGINE OR TRANSMISSION WILL COST THOUSANDS OF DOLLARS", they expect the engine or transmission to last the useful lifetime of the car. The battery in an EV is designed to do the exact same thing. There was tons of this when the Prius came out, but the widespread failure of Prius batteries never materialized. Even better, there are now companies who will sell rebuilt / remanufactured batteries at lower cost. Some people even will replace failed battery modules.

      EVs also beat the tar out of ICE in terms of operating cost and simplicity. There is "car stuff" that can go wrong -- you smack a curb in an EV and you are going to have to replace stuff. But you don't have an exhaust system, spark plugs, air intakes, emissions controls, multi-speed transmissions, etc. An EV's motor has one spinning part. The transmission is one gear. Brakes largely go unused because of regenerative braking. You don't have to change the oil, and so on and so forth. A friend of mine who has a Leaf had to replace tires and wiper blades, that's it.

      I have a Volt I got used, it's fantastic. It's very likely that my next car will be a full on EV. The driving experience is so much better than any of the ICE cars I drove before it. It's only when the battery runs out of range and it switches to hybrid mode am I reminded of the ICE. Driving my wife's van just feels like a step backwards, I need to wait for torque to happen and it makes all this noise, unlike the no noise the Volt makes when in EV mode.

If you also penalize hydrocarbon burning for the waste and pollution produced by oil extraction, batteries still end up ahead in the current US or European economies (on emissions, not yet on cost).

    An ICE tops out around 30% when it's running at it's peak efficiency. That requires an immaculately maintained engine and operating it within a very narrow part of its functional range. Whenever your ICE vehicle is doing anything other than cruise control at its most efficient speed it is way off that efficiency number. Power plants will spend much more of their lifetime operating at or near peak efficiency than an ICE in a car will. Electric motors are also far more efficient with a much broader functional power band than any ICE. Of course we use transmissions in ICE vehicles to try and get more use out of the narrow operating range, but that adds more moving parts that need maintaining as well as more power losses.

    There is also the matter of the amount of energy that goes into processing petroleum so that it can be used as a fuel in a car. The fossil fuels used in most power plants, coal and natural gas, don't require nearly as much processing. There is also a lot of value in centralizing, or outsourcing as you say, the CO2 production. Because the CO2 is being generated at one place instead of thousands of individually maintained tailpipes, it is much easier to control and maintain.

    Which brings up the fact that most people don't do much for maintenance on their cars. They might get the oil changed regularly.

It categorizes electric vehicles according to the country of manufacture and the country of operation to compute when, in the life of the car, the total CO2 expenditure to build and power the electric vehicle begins to beat the total CO2 expenditure to build and power a high-efficiency diesel vehicle. In countries like Germany, where the primary power grid is still largely coal powered, building and operating an electric vehicle can take ten years before being a net CO2 reduction over a diesel vehicle. In countries with a higher percentage of renewable power, this point is going to be sooner. It's an unavoidable consequence of the production of the power system of an electric car being more energy-intensive than making an IC engine and drivetrain. It does raise another consideration regarding electric vehicles -- if the expected functional lifespan of the battery pack is less than the break-even point, it makes electric vehicles less competitive in this regard, because of the jump in CO2 'cost' for replacing the batteries. This points up the fact that the batteries are the critical design factor in EVs, and that making more efficient and longer-lasting batteries using more efficient production methods is going to be what brings the CO2 footprint of EVs down to a point that makes them clearly superior to IC vehicles at any point in their functional life.

    TL;DR, it doesn't demonstrate that EVs are worse than IC vehicles, but that both the production methods and power generation for EVs are fundamental factor in making EVs a more 'environmentally friendly' vehicle -- just buying an EV and thinking that you're immediately doing your part to reduce CO2 emissions may not be true for quite a few years after the purchase, depending on what the power generation in your driving area looks like.
