Electric company: GM makes statement with Bolt, Volt

General Motors CEO Mary Barra has sent a strong message to the auto industry: It’s serious about producing electric cars for the middle class.

One of the most talked-about vehicles unveiled Monday at the North American International Auto Show in Detroit was GM’s Bolt, an all-electric concept car that could go on sale in 2017, the Detroit Free Press reported. The company also officially unveiled its redesigned Volt, a plug-in electric-and-gasoline hybrid that got a first glimpse at CES in Las Vegas last week.

The Bolt’s price tag is $30,000, including the $7,500 federal tax incentive, GM North America president Alan Batey said. It would get about 200 miles on one battery charge.

As the Detroit News reported, GM is positioning the Bolt as an affordable EV option:

“This is truly an EV for everyone,” Barra said. “For most people, this can be their everyday driver.”

Batey said the Bolt isn’t aimed at Tesla, noting Tesla’s current average transaction prices are above $100,000.

“They are for the rich and famous. This is for the people,” Batey said of the Bolt. “I would probably counter and say I haven’t seen Tesla with anything like this.”

Despite what Batey said, Forbes took the unveiling as a direct challenge to Tesla:

The Bolt is a clear shot at upstart rival Tesla, which has said it is working on a less-expensive version of its $70,000+ Model S. Dubbed the “Model 3,” it would cost somewhere between $30,000-$40,000, a clear attack on the most popular segment of the automobile market.

Barra is clearly looking to meet the challenge. The Bolt, she said, would be an “all-electric vehicle for the real world.” Tesla CEO Elon Musk is scheduled to appear at a related auto industry conference in Detroit on Tuesday afternoon.

As for the revamped Volt (with a “V”), the biggest news is that the battery range has gone up to 50 miles. At that point, the gasoline engine, a 1.5-liter “range extender,” kicks in, pushing the limit to 400-some miles before the vehicle needs a charge or a fill-up. With the electricity and gas range combined, mpg on the highway is about 41. In all-electric mode, however, it’s 102 for a gallon-of-gasoline equivalent, thanks to the new 18.4-kilowatt-hour lithium battery.

Auto Blog notes:

To compare, today’s four-seat 2015 Volt has a 38-mile range from a 17.1-kWh battery in a powertrain that offers 37 mpg and 98 MPGe. So, across the board, there are notable improvements.

The blog has much more about the dashboard improvements, and the Verge has a bunch more photos.

The Volt is expected to be in showrooms in the second half of 2015 as a 2016 model.

Garage filling stations — are we getting close?

One of the greatest appeals of switching to an alternative-fuel vehicle — electric, compressed natural gas or hydrogen — is saving money and freeing yourself from the clutches of foreign oil. But another is being able to supply your own fuel from a garage filling station where you may even be able to generate some of it yourself.

All this takes on a certain air of necessity when you realize that most of the infrastructure for recharging or refilling is not yet in place. In many cases, the garage may be the best option right now. So let’s run down some of the different options available and see how they stack up as being economical and practical.

Let’s start with the easiest one — electric cars. There are three types of chargers available to owners of a Prius, Leaf or Chevy Volt. The first is a Level 1 “trickle” charger, which is just a basic 120-volt line that plugs into any three-pronged outlet. This is the standard plug-in for all EVs. The problem is the amount of time it takes for a complete charge. For the Leaf, it takes close to 21 hours, which means that you can’t even do it overnight. For hybrids there’s some leeway since you can always revert to the gas motor and do some brake recharging as well. But if you’re planning to rely completely on a home outlet, you’d better have a second car.

More favorable is a Level 2 240-volt circuit. If you have an electric clothes dryer in your house, you’re already equipped. If you don’t have a 240-volt system at home, installation is easy enough. It will require a 40-amp circuit breaker, which may need a permit from the local building department, but the job is simple enough. Recharging time will be cut to less than eight hours, enough for an overnight. puts the price at $600 -$700, although vendors such as ClipperCreek lists some for less.

If you really want to go really high-tech, you can move up to a Level 3 480-volt power supply that can give you an 80 percent charge in half an hour. The whole package costs $30,000, but with federal tax breaks and some help from the car companies, you can get it down to $10,000. Nissan offers a unit for $9,900. You could probably recoup some of the costs by recharging EVs for your neighbors, but you might need a zoning variance.

So how about compressed natural gas? What are the options there?

The Honda Civic is the only CNG passenger vehicle being sold in the United States. (Most of the progress has been with delivery trucks and long-haul trailers.) There are currently 1,000 CNG filling stations across the country, but half of them belong to companies that are using them for their fleets. Only about 500 are available to the public. So, unless you’re traveling along an Interstate and can make it to one of Clean Energy Fuels’ new truck stops, you’re going to have a hard time.

Refilling at home, however, isn’t all that impractical. More than half the residences in the country are equipped with natural gas for home heating, cooking or hot water. The trick is to get a device that can compress this household gas to be used in your car.

Honda originally offered a home refueling kit, the Phill, which costs $4,500 and could do a refill overnight. Honda stopped making the offer after 2012; however, due to concerns about the widely varying quality of non-commercial gas and the possibility of home devices allowing moisture to collect in the fuel system. For those willing to take the chance, the Phill is still available from its manufacturer, BRC FuelMaker. The question is, “Why is it so expensive when the same pump would cost 10% if it filled air bottles?” There is a regulatory review needed to reduce the cost.

Seeking to promote the technology, the Department of Energy (DoE) handed out grants a few years ago to encourage companies to develop affordable home systems. Now one of them may have come through. The Eaton Corporation of Cleveland, already prominent in the field of electrical charging stations, announced in 2012 that it plans to market a CNG home refueling device by 2015. “The system will use liquid to act as a piston in compressing the gas,” says Chris Roche, vice president at Eaton’s Innovation Center. “We have also developed an innovative heat exchange technology that will improve efficiency and cut costs dramatically.” Eaton is aiming at production costs of $500, which means the device could sell for less than $1,000. GoNatural, a Salt Lake City company, has also promised to have a product available by 2015. “It could be a game changer,” said New York Times reporter Paul Stenquist, in profiling CNG home compressors last October.

So, what about hydrogen? Is there anything available there? Hydrogen is very difficult to deal with. It is the smallest atom and will leak through just about anything. It’s hard to store and transport and must be kept under high pressure.

The upside, however, is the possibility of generating your own hydrogen, particularly from renewable resources. This can be done with simple electrolysis of water, which only requires an electric current. If you can generate that current with wind or solar energy, then you are essentially powering your car for free.

Making it happen is probably a long way off, although people are working on it. HyperSolar, Inc., a Santa Barbara company, has announced “proof of concept” of a method for generating solar hydrogen. “Using our self-contained particle in a low cost plastic bag, we have successfully demonstrated our ability to mimic photosynthesis to produce renewable hydrogen from virtually any source of water using the power of the Sun,” said CEO Tim Young while making the announcement. Horizon Fuel Cells, a Singapore company, released a “desktop” hydrogen generator in 2010 that generates hydrogen through electrolysis from any power source. It sells for $250 on Amazon. Although the company is targeting much smaller fuel-cell devices, it could eventually scale up to handle quantities needed to run a hydrogen fuel cell car

Altogether for cutting loose from the local gas station, electric vehicles are the best bet for now. But natural gas in its many forms — including methanol — are moving up and renewable hydrogen may be on the horizon. With home-generating devices proliferating, it is not hard to see all this eventually making a dent in our consumption of fossil fuels.
