The IBM Battery 500 Revs Up

us__en_us__energy__battery500_info2__748x443Although IBM is largely focused on computer science issues, it has labs all over the world that do all kinds of things – after all, IBM is also focused on making money. This page contains a good slice of what IBM is doing in the energy sphere.

But I was most interested in its battery technology project for electric cars.

IBM correctly notes drivers’ range anxiety, the fear that they’ll be in the middle of nowhere when the battery runs dry. Using today’s lithium-ion technology, electric cars can get about 100 miles on a charge – with the air conditioning blasting, 4 miles (kidding.)

So that’s the problem. Here’s the proposed solution:

Recognizing this [range anxiety], IBM started the Battery 500 project in 2009 to develop a new type of lithium-air battery technology that is expected to improve energy density tenfold, dramatically increasing the amount of energy these batteries can generate and store. Today, IBM researchers have successfully demonstrated the fundamental chemistry of the charge-and-recharge process for lithium-air batteries.

It’s even green beyond green.

During discharge (driving), oxygen from the air reacts with lithium ions, forming lithium peroxide on a carbon matrix. Upon recharge, the oxygen is given back to the atmosphere and the lithium goes back onto the anode.

Well, almost. I assume it is giving back less oxygen than it is taking, but if oxygen is your exhaust, that’s not bad. (There’s more to say on this. This part isn’t really working yet.)

And it gets (potentially) 500 hundred miles per charge.

I have no idea whether this can be scaled to work in cars or even work as advertised – on a corporate web site, you can’t expect much more than good news. Extreme Tech tries for a little more context:

Lithium-air batteries aren’t a new idea: They’ve been mooted since the 1970s, but the necessary tech was well beyond the capabilities of then-contemporary material science. Today, with graphene and carbon nanotubes and fancy membranes coming out of our ears, it seems IBM — with assistance from partners Asahi Kasei and Central Glass — now has the materials required to build a lithium-air battery. There is a video embedded below that details the electrochemical process of an li-air battery.

We should also note that the project utilizes IBM’s Blue Gene supercomputer to work out the chemistry – so it is selling its computers as being able to do such things.

Mobile & Apps is a little clearer on the downsides of the technology – or at least the challenges it is presenting:

[IBM’s Winfried] Wickle reckoned that one of the challenges was the belief that lithium-air batteries are rechargeable, but that turned out to be false. "What was thought to be rechargeability was in fact confused with destruction of battery." In theory, upon recharge the battery was supposed to release pure oxygen to the air. Instead of the oxygen, however, it was releasing carbon dioxide, the very greenhouse gas that electric vehicles aim to reduce.

Oops. That wouldn’t be good. The story goes to say that the solution, as in Idiocracy, might be electrolytes. This paints the technology as maturing but still uncertain and the outlook hazy but clearing. It’s the classic wait-and-see, but it’s worth doing until the nascent electric car market collapses or as long as IBM’s patience (and money) holds out. This would be a big deal if it came to fruition.

The nuclear angle is the same as it always has been on this subject. Electric cars need electricity – it they get traction on their own or are mandated at some point, a lot of electricity. Some kinds of energy might seem to mitigate the benefits of an electric car – nuclear much less so. Benefit upon benefit, you might say.

Good article.
It's amazing how much the public think electric cars are juiced with magic, with small reality-adjustment by commercials and news media.

Excellent source of CO2! We should keep this technology on hand for the next global cooling cycle when Time magazine flips back to its previous scare topic that we are all going to freeze to death in the impending ice age. We can just fire up the old coal plants again and use them to charge our lithium-air batteries to help stop global cooling... as if...

Knowing What You’ve Got Before It’s Gone in Nuclear Energy

The following is a guest post from Matt Wald, senior director of policy analysis and strategic planning at NEI. Follow Matt on Twitter at @MattLWald.

Nuclear energy is by far the largest source of carbon prevention in the United States, but this is a rough time to be in the business of selling electricity due to cheap natural gas and a flood of subsidized renewable energy. Some nuclear plants have closed prematurely, and others likely will follow.
In recent weeks, Exelon and the Omaha Public Power District said that they might close the Clinton, Quad Cities and Fort Calhoun nuclear reactors. As Joni Mitchell’s famous song says, “Don’t it always seem to go that you don’t what you’ve got ‘til it’s gone.”
More than 100 energy and policy experts will gather in a U.S. Senate meeting room on May 19 to talk about how to improve the viability of existing nuclear plants. The event will be webcast, and a link will be available here.
Unlike other energy sources, nuclear power plants get no specia…

Making Clouds for a Living

Donell Banks works at Southern Nuclear’s Plant Vogtle units 3 and 4 as a shift supervisor in Operations, but is in the process of transitioning to his newly appointed role as the daily work controls manager. He has been in the nuclear energy industry for about 11 years.

I love what I do because I have the unique opportunity to help shape the direction and influence the culture for the future of nuclear power in the United States. Every single day presents a new challenge, but I wouldn't have it any other way. As a shift supervisor, I was primarily responsible for managing the development of procedures and programs to support operation of the first new nuclear units in the United States in more than 30 years. As the daily work controls manager, I will be responsible for oversight of the execution and scheduling of daily work to ensure organizational readiness to operate the new units.

I envision a nuclear energy industry that leverages the technology of today to improve efficiency…

Nuclear: Energy for All Political Seasons

The electoral college will soon confirm a surprise election result, Donald Trump. However, in the electricity world, there are fewer surprises – physics and economics will continue to apply, and Republicans and Democrats are going to find a lot to like about nuclear energy over the next four years.

In a Trump administration, the carbon conversation is going to be less prominent. But the nuclear value proposition is still there. We bring steady jobs to rural areas, including in the Rust Belt, which put Donald Trump in office. Nuclear plants keep the surrounding communities vibrant.

We hold down electricity costs for the whole economy. We provide energy diversity, reducing the risk of disruption. We are a critical part of America’s industrial infrastructure, and the importance of infrastructure is something that President-Elect Trump has stressed.

One of our infrastructure challenges is natural gas pipelines, which have gotten more congested as extremely low gas prices have pulled m…
