Gates-backed TerraPower pitches new nuclear tech

To leap to the next generation of nuclear power technology, Bill Gates-backed start-up TerraPower is approaching countries rather than individual utilities or financiers.

Gates last week disclosed that he brought up TerraPower’s fourth-generation nuclear power technology with government officials at the Chinese Ministry of Science and Technology during a visit to China. “TerrPower is having very good discussions with [China National Nuclear Corporation] and various people in the Chinese government,” Gates told the Associated Press.

Bellevue, Wash.-based TerraPower then said that the company has visited energy experts in the U.S. France, India, Japan, Korea and Russia, but that “there were no deals to at this time.”

While Germany and Japan are backing away from nuclear power, the United Kingdom is looking in completely the opposite direction – 8 new nuclear plants are scheduled to be built. As a close neighbor, Germany has a number of words on the topic (all of them polite, but not particularly flattering).

Germany’s announcement of zero nuclear was prompted by the Sendai quake and the Fukushima nuclear meltdown last spring, as Clean Technica readers may remember, but those phase-out plans were already in place. The announcement gave rise to fears of insufficient power feeding into the grid anyway. However, Jochen Flasbarth, president of Germany’s EPA, pretty much thinks the entire idea is ridiculous, and furthermore that nuclear power is not the answer to a stable power supply:

If you thought the Fukushima disaster derailed nuclear power worldwide, look again.

Evacuations and the havoc caused by meltdowns at four reactor cores at the Fukushima power plant earlier this year prompted Japan to shift away from nuclear power and recatalyzed a nuclear phase-out in Germany. But many countries remain enthusiastic about nuclear power, and interest in newer technologies has increased because they are safer, according to a panel of industry professionals here at the MIT Energy Finance Forum on Friday.

“Our investors have a very long time horizon and the reason they supported it is the long-term societal implications and the potentially significant returns from that (so) we haven’t seen any wavering of support,” said Tyler Ellis, a project manager at TerraPower. “Our development partners are trying to accelerate the time scale (of building plants) due to the energy security and safety.”

India's New Nuclear Build


Protest at Jaitapur over planned construction of two new nuclear reactors.

A series of protests that began in October have delayed the hot start of two Russian 1000- MW VVER reactors in the Tamil Nadu state on India’s southernmost coastline. Additional protests, some of them violent, have set back the start of construction of two French 1650-MW EPR reactors in the Maharashtra state on India’s west coast some 400 km (250 miles) south of Mumbai.

When it comes to keeping airport runways clear of ice, there are several options, including the use of chemical, thermal, electric and microwave technologies. All of these methods can be expensive, as they require either a considerable amount of electricity, or a number of human workers. Engineering researchers at the University of Arkansas, however, are developing a new system that would use the freely-available power of the Sun to keep runways from freezing up.

Imagine if nuclear power was safe, terror-proof, and fueled by a plentiful, ubiquitous element. Sound like a pipe dream? Maybe it is. Maybe not.

A couple nights ago, I dropped by the Vice magazine offices in Brooklyn to check out a new documentary on thorium put together by Motherboard.tv. (Full disclosure: the video was produced by Alex Pasternack, a former contributor here at TH.) The film, The Thorium Dream, examines the history of an alternative kind of nuclear power, one tested decades ago but never embraced.

60-90 of UK Electricity Could Come from Renewable Energy

A new report published by WWF UK finds that 60% to 90% of the UK’s electricity could come from renewable energy sources such as wind, tidal, and solar energy by 2030.

“By using this amount of renewable energy, we can decarbonise the power sector without resorting to new nuclear power. We will also be able to maintain system security – that is, provide enough electricity at all times to make sure there’s never a risk of the ‘lights going out’,” the report states.

MIT team designs concentrated solar thermal system that could store heat in vats of molten salts, supplying constant power

The biggest hurdle to widespread implementation of solar power is the fact that the sun doesn’t shine constantly in any given place, so backup power systems are needed for nights and cloudy days. But a novel system designed by researchers at MIT could finally overcome that problem, delivering steady power 24/7.

The basic concept is one that has been the subject of much research: using a large array of mirrors to focus sunlight on a central tower. This approach delivers high temperatures to heat a substance such as molten salt, which could then heat water and turn a generating turbine. But such tower-based concentrated solar power (CSP) systems require expensive pumps and plumbing to transport molten salt and transfer heat, making them difficult to successfully commercialize — and they generally only work when the sun is shining.

As a group, women seem to be pretty on board for the whole clean energy thing. Last year a national poll by the Women’s Council on Energy and the Environment found that 43 percent of women named moving to clean energy as the single most important goal for the United States.  A full 90 percent of women said solar energy should be a “very or somewhat important part” of our national energy policy.

But while women are definitely interested in clean energy, there are some indications that the clean energy industry hasn’t yet fully or effectively engaged them as consumers. Here at One Block Off the Grid, for instance, we’ve often puzzled over the fact that only 18 percent of our members are women. Live solar educational events have about that same rate of participation from women, even as rates of female home ownership are rising.

Recently, we were pretty surprised when the female founder and CEO of a highly reputable California solar installation company told us her sales reps often return from the field complaining that a woman has blocked the sale of a solar system, while her husband, by contrast, was highly motivated to buy.

So what’s going on here? Why do women express such keen interest in solar but sometimes seem to block it at the household level?

According to that installer we mentioned earlier, many women still think of an actual solar system in the same category of “expensive frivolous toy, like the Ducatis their husbands all want.” She agrees this misunderstanding isn’t necessarily their fault. The solar industry itself is dominated by men, so its marketing messages tend to be of a gear-centric, size matters sort that resonate more strongly with a male audience. (Yes, this is a generalization but we’re just exploring here.)

Just how male dominated is the solar industry? Since 1991, Colorado-based Solar Energy International has offered training in renewable energy technology and reports that 85 percent of workshop participants are men. Most solar companies would report a similar ratio of male employees to female. At One Block Off the Grid, 75 percent of employees are men and 25 percent, women.

The fact that the industry itself is dominated by men has some very real-world implications for solar sales. Anecdotally speaking, our observations of sales reps’ interactions with homeowners reveal some of the same patterns that keep women out of car showrooms at higher rates than men; often when a solar sales rep is addressing both a man and a woman — as they often are — the rep will unconsciously devote more attention, eye contact, and bids for engagement to the male homeowner.

Another reason women might be somewhat absent from the solar space is that on a practical level, they’re still a little unclear on what solar has to do with climate change. In that national poll we mentioned above, 93 percent of women incorrectly thought that cars — not electricity-generating power plants — were the primary source of air pollution and CO2 emissions. (Over 60% of electricity from utilities in the U.S. comes from the burning of coal and other fossil fuels like natural gas.) There’s some reason to think that as these facts become more widely known, more female consumers will become interested in purchasing clean energy for their households.

By the way, the poll didn’t survey men, so it’s unclear whether women are any less aware than men that power plants are the leading source of air pollution. The pollsters simply made the point that because women are so pivotal in making major household purchase decisions, they have a lot of power to affect change on a grand scale once they do become aware. Family health will likely play a role in this too. Seventy percent of women said they’re very or somewhat worried about the impact of air pollution on the health of their children, so it stands to reason that as the relationship between coal-fired power plants and things like asthma and bronchitis becomes more widely publicized, women will seek out solutions like solar in greater numbers.

Another key motivator for women is likely to be solar’s strong financial benefits. Research shows that women are the ones paying utility bills in 77 percent of households. If the solar industry, therefore, was able to reach women more effectively with the message that the average solar household saves between $1,200 and $2,000 a year in avoided electricity bills, it may see an uptick in adoption among homeowners at large.

After all, a Ducati will never save a household $1200 a year or pay for a kid’s college education.

So the problem is not that women are blocking clean energy adoption. The problem is that most clean energy companies haven’t yet learned how to talk about its products in ways that resonate with women. Some industry folks have even speculated that women are opposed to solar on an aesthetic level, but we’re not buying that. There are good indications, in fact, that women are every bit as excited about solar as they claim to be. Last summer One Block Off the Grid hosted a solar webinar just for women and over 500 women registered for it. That Colorado-based solar training company recently started offering panel installation classes just for women and reports demand for it is high. So, interest in solar among women is strong; it’s just waiting to be fully and effectively tapped.

In fact, as the financial and environmental benefits of solar become more well known, we’re really excited about women’s potential for advancing clean energy in the U.S. and beyond. As the president of Women’s Council on Energy and the Environment put it, “Women have a tremendous opportunity to help solve this defining issue of our time, and it all starts with learning more about how electricity is produced and which sources are clean.”
