Can Flex-Fuel Cars Break OPEC?

Bob Zubrin is a clever guy. If we do a crewed Mars mission in our lifetime, it will probably be based on his ideas - which include using a nuclear reactor to synthesize fuel for the return mission out of the Martian atmosphere.

That said, I think he's probably barking up the wrong tree here.

Aside from the dubious economics, there's several technical issues which makes this alternative less likely.

If you're going to make liquid fuels from coal for OPEC-busting, the process of making diesel from coal is not very different to making methanol, and there are already car and truck engines in mass production using the stuff.

As an extra bonus, diesel engines are much more efficient than spark-ignition engines because of the much higher compression ratio.

In any case, this doesn't solve the problem of carbon dioxide emissions from combustion, which are highly likely to be the subject of regulation soon.

For what it's worth, my best guess is that plug-in hybrids with increasingly long all-electric ranges, hopefully powered by nuclear electricity, will become increasingly commonplace through the 2010s.

Actually, the flex-fuel cars use E85, which is nominally 15% gasoline (for cold start) and 85% Ethanol. But it does not matter, you can make also Ethanol or Butanol from coal, or CO2 as feedstock.
With dedicated Ethanol/Methanol engines the achievable efficiency is actually HIGHER than the efficiency of diesels.
With a high temperature reactor as process heat source the "mine to wheel" efficiency would be higher than either hydrogen fuel cell or battery electric. And it is doable with the existing liquid fuel infrastructure and without much retooling the existing car fleet.
Also gets away from the rising commodity prices for battery or fuel-cell materials.

Activists' Claims Distort Facts about Advanced Reactor Design

By
Below is from our rapid response team . Yesterday, regional anti-nuclear organizations asked federal nuclear energy regulators to launch an investigation into what it claims are “newly identified flaws” in Westinghouse’s advanced reactor design, the AP1000. During a teleconference releasing a report on the subject, participants urged the Nuclear Regulatory Commission to suspend license reviews of proposed AP1000 reactors. In its news release, even the groups making these allegations provide conflicting information on its findings. In one instance, the groups cite “dozens of corrosion holes” at reactor vessels and in another says that eight holes have been documented. In all cases, there is another containment mechanism that would provide a barrier to radiation release. Below, we examine why these claims are unwarranted and why the AP1000 design certification process should continue as designated by the NRC. Myth: In the AP1000 reactor design, the gap between the shield bu...

Nuclear Utility Moves Up in Credit Ratings, Bank is "Comfortable with Nuclear Strategy"

By
Some positive signs that nuclear utilities can continue to receive positive ratings even while they finance new nuclear plants for the first time in decades: Wells Fargo upgrades SCANA to Outperform from Market Perform Wells analyst says, "YTD, SCG shares have underperformed the Regulated Electrics (total return +2% vs. +9%). Shares trade at 11.3X our 10E EPS, a modest discount to the peer group median of 11.8X. We view the valuation as attractive given a comparatively constructive regulatory environment and potential for above-average long-term EPS growth prospects ... Comfortable with Nuclear Strategy. SCG plans to participate in the development of two regulated nuclear units at a cost of $6.3B, raising legitimate concerns regarding financing and construction. We have carefully considered the risks and are comfortable with SCG’s strategy based on a highly constructive political & regulatory environment, manageable financing needs stretched out over 10 years, strong partners...

Wednesday Update

By
From NEI’s Japan micro-site: NRC, Industry Concur on Many Post-Fukushima Actions Industry/Regulatory/Political Issues • There is a “great deal of alignment” between the U.S. Nuclear Regulatory Commission and the industry on initial steps to take at America’s nuclear energy facilities in response to the nuclear accident in Japan, Charles Pardee, the chief operating officer of Exelon Generation Co., said at an agency briefing today. The briefing gave stakeholders an opportunity to discuss staff recommendations for near-term actions the agency may take at U.S. facilities. PowerPoint slides from the meeting are on the NRC website. • The International Atomic Energy Agency board has approved a plan that calls for inspectors to evaluate reactor safety at nuclear energy facilities every three years. Governments may opt out of having their country’s facilities inspected. Also approved were plans to maintain a rapid response team of experts ready to assist facility operators recoverin...
