From Guest Blogger Stephan Williams: Integrated EV/Distributed Energy Proposal
This proposal involves a simple synergy of government incentives and distributed energy storage applications. But first, I’d like to briefly discuss some of the issues that this solution addresses.
The Issues
Climate Change
Humans are releasing too much CO2 and other gases into the atmosphere. This is causing heat from sunlight to stay trapped in the atmosphere and increase global temperatures. One of the major issues with this is that it causes arctic ice to melt and this melting ice releases more CO2 and other gasses which have an even more pronounced greenhouse effect, in essence causing a positive feedback loop (positive feedback is almost always bad, and in this case it definitely is). We need to figure out ways to decrease CO2 emissions and reverse the effects of climate change.
Global Economic Recession
Without going into this issue too deeply, the global economy is experiencing a slowdown due to numerous problems. The world need to create healthier financial systems and more sustainable businesses. Too much of the global economy depends on unsustainable business practices.
Energy Infrastructure Crisis
The current energy infrastructure in the U.S. is antiquated. It struggles to support delivery of peak loads and is literally falling apart in many locations. Unfortunately, a complete overhaul of the system would cost trillions of dollars; a piecemeal solution is the only feasible answer, but there needs to be a vision or the inefficiencies will come back to haunt future engineers.
The Proposal
Bear with me as I talk through a proposal that I think will help alleviate some of the preceding issues.
The Peak Energy Infrastructure
One of the big issues with electric utilities these days is that they have to build and maintain enough generation infrastructure to deal with peak load. The problem here is that peak load only happens 1% of the time, annually (I’m ballparking, but it really is very low). But if a utility didn’t build adequate generation the system would fail at the worst possible times (think of the hottest day of the year and everyone’s ACs are shutting off; think of the coldest day of the year and everyone’s electric heaters are switching off). Therefore, utilities must build generation capability for these worst case scenarios.
Another way to deal with this issue is to store energy when demand is low and put that energy back on the grid when demand spikes back up. The problem with this solution is that battery technology is not where we need it to be in terms of energy density and cost- and so utilities cannot afford to buy huge batteries and other types of electricity storage systems in order to implement this type of arbitrage scenario. That’s where electric vehicles come in.
Electric Vehicles as Storage Facilities
Electric vehicles (EVs) have batteries on board, by design and definition, so why not use these batteries to store energy? Well, first of all, as mentioned, battery technology is still relatively green for these uses. Plus, you would need hundreds of thousands, even millions of EVs to make a difference nationwide. But what if everyone had an EV in their garage? Sure, but who wants to volunteer their EV and its precious battery in order to solve an esoteric problem such as presented here?
The Feds and Our Money
Enter the federal government. It can subsidize American electric vehicle manufacturers and provide incentives for car-buying consumers to purchase EVs. But here’s the catch: when you buy a government-sponsored EV you sign a contract saying that your car will be available for arbitrage use a certain amount of time every week, or month, or whatever. Different contracts can be drawn up for different needs. So what this amounts to is the federal government supporting domestic electric car manufacturers and charging stations and battery manufacturers, and easing the pain of purchasing a relatively expensive electric vehicle in exchange for support of a larger solution. In this way the economy can be stimulated (and you can bet battery research will boom because of this, and EV prices will come down as a result) and the energy storage issue can, to a certain extent, be dealt with. And as far as the atmosphere is concerned, more EVs on the road, displacing internal combustion engine cars, can only help lower the CO2 levels in the air. As a side benefit, air quality will improve and smog, emphysema, and cancer levels will drop. Sounds good to me.
The Roadblocks
Now I’m not a federal subsidy guru or an economist by any stretch of the imagination, but I like a good idea when I hear one, even when it’s in my own head. I tried to consider some of the arguments against a solution like this. Here’s a few, with my thoughts on them. I’d also like to hear some more from readers in the comments.
• The Feds shouldn’t be subsidizing anything.
Well, if that’s what you think then that’s that, but in my political philosophy the whole purpose of government is to support and engender solutions that benefit everyone. You may say the taxpayer doesn’t benefit in this scenario, but I think averting a climate disaster and lowering cancer rates benefits everyone, save oncologists on Mars.
• Too expensive, won’t make a dent.
Fair enough, this is an expensive endeavor. But as long as we’re spending billions on wars and propping up a toxic petroleum industry with insane subsidies, I think we can find the relatively modest amounts needed to jumpstart a beneficial cycle like the one proposed here.
• Too many variables, where’s the business case, you’re making numbers up, etc.
Again, fair enough. I thought of this yesterday while working on a number of projects and it sent a shiver through my spine. I figured instead of sitting on it and letting it grow stale I’d get the idea out there to the smart people of the world. We’ve got huge issues we need to deal with sooner than later. I hope this proposal can gain traction and do some good. We’ll see. Please let me know your thoughts.
Added note: this could have a huge impact on storage of intermittently generated renewable energy. This will require smart-grid like connectivity of EV chargers and utility operations, but we’re headed that way anyway- why not jumpstart it with something beneficial like this?
The Biggest Road block (Mind Block!), is that it seem to Ignore the Newtonian Science. ..The Laws of the Motion.
Not exactly sure how that is relevant.
It may take a little while to explain this, but to make a good start let me say it BOLDLY that Anything presently moving on the roads, rails (may be even sky or sea) or roaming on other planet (our mars rover), Blatantly Ignores Fundamental Laws of Physics or The Newton’s Laws of motion; meaning They are nor allowed to go on its own as much as it likes (free-wheeling like Bicycle) and the second law that states F=ma or use of an IVT or infinitely variable transmission. The Evolution of EV has not gone over this fundamental (mechanical) problems in entirety and therefor has not made serious in-road in to the future. We still talk about hundreds of kilowatts of electric motors with associated battery problems (even fire -sorry for this), Grid problems, ultimately coming to coal and so on, but Never really questioned the aspects of physics,solution of which are mechanical in nature and simply going for electric without solving problem of Mechanical Engineering or dealing with Laws of physics was taking us nowhere. So If we were to conclude that whatever we drove so far in History be it Automobile or EV have been on wrong principles or Ignorance of physics. ..and like an i-Pad made of Valve radio of a size of a Train consuming an equivalent energy of driving a train; in absence of inventing a transistor.
Somehow you’ve confused me even more with your explanation.
You did make me think about something though: many say we should not support technologies that currently cannot compete with the status quo- but when the status quo is destroying everything that all living things require for existence, then there may be an argument for supporting the “less economical” solution if it will lead to a non-apocalyptic long term situation. EVs qualify for that in my book.
Not sure if that’s what you’re talking about, but trying to read through your explanation made me think of that for whatever reason.
I will also say that I’ve ridden in an electric vehicle, so unless my entire existence is a dream then EVs have most definitely overcome The Newton’s Laws of motion.
If that was so, If a Horse cart with single horse can carry a full family and luggage; why EVs are not Single Horse power (less than 1kw).
The problem simply put is that you need to sell it to the electric utilities. Have you ever watched the power line voltage for a long period of time? I had a wall mounted meter in my classroom for several years and every day the voltage varied from 100 as a low to 135 as a high and several times up and down during the weekday as I was teaching Electronic Technology. A phone call informed me that they were allowed to go down to 85 volts and up to 165 volts in the industrial area the vocational school was located in. And if it was residential the range went to 95 to 130 volts.
That is a voltage regulation issue, which will improve over time with smart meter installations and distribution automation. EV chargers will require internal regulation to ensure that the batteries aren’t damaged.
The utilities will need to come on board, but thankfully we have commissions which regulate most of them.
Steven, I like your plan.
I envision more distributed, renewable generation. Every wind turbine tower should have PV solar panels up and down the south side of the towers. Maybe they could track the sun.
Every rooftop in America should have both PV solar and/or thermal solar panels. Hot water heating with the sun is cost effective today. Solar hot water is a type of solar storage.
Grid infrastructure can be upgraded with electrical storage at the substation level. ZBB has a grid storage solution, as did A123 before they went bankrupt. There are others. An electrical storage unit designed for grid voltage regulation wouldn’t need to be huge, if there was one unit at each substation.
Tesla’s solar chargers are also a great innovation!
I believe the Ford hybrids should run on alternative fuels and electricity. Not gasoline! Keep up the good work!
This company has an intriguing product: http://demandenergynetworks.com/
More distributed generation is coming, there’s no stopping it. Integrating it into the grid in highly efficient ways is one of the big challenges of the power industry. We need to inspire engineering students to think of the power industry as being as sexy and cool as the microprocessing industry. Fun challenges ahead!
