Peak coal in Christmas stocking?

A new report from the American Geophysical Union suggests governments may be substantially over-reporting coal reserves, from Ars Technica:

Such fallacious reporting is nothing new—the United States government happily overestimated oil reserves in the 1950s and 1960s until peak oil hit the lower 48. David Rutledge, professor of engineering and applied sciences at the California Institute of Technology, claims the same mistakes are being repeated with coal.

His results, reported in a panel discussion at this year’s American Geophysical Union meeting, state the world only has 662 billion tons of coal, including reserves already exploited. The estimate is well short of the 1,027 billion tons remaining in proven and projected reserves, according to the World Energy Council.

Leading to the possibility of imminent peak coal.

Is Peak Oil a lie?

2 Comments

Alaskan oil pipeline at PaxsonI’m going to shamelessly crib from io9 and link to the Cleantech Group’s write-up of a talk by an environmental futurist named Peter Schwartz, because he has a pretty provocative point to make. In a nutshell – Peak Oil is a lie, and it’s a lie that could make things worse rather than better.

Peak oil is wrong. We really don’t know how much oil there is in most of the oil reservoirs of the world. Oil reservoirs are complex geological structures, and most of the data is in private hands, or in state governments, and they are not particularly forthcoming about how much is there.

However, he’s far from denying that climate change is a problem:

We are not going to run out of oil before the issue of climate change drives change. It’ll be costly oil. But it’ll be climate change catastrophes [such as sudden, unexpected displacement of large numbers of people, and massive property damage], and more expensive oil, not the fact that we’re running out of oil, that will drive change…

Of course, Schwartz is just one man, and an awful lot of people seem to be pretty convinced that Peak Oil is real, so I can’t argue that either way because I don’t have the knowledge or evidence to do so. But it’s interesting (and refreshing) to hear someone deny Peak Oil without denying climate change at the same time. [image by Steve Deger]

Rainbows and Unicorn Farts…

…are about as likely to solve the two little problems of peak oil and global warming as hydrogen fuel cell technology.

hydrogenSorry to flog a dead horse here but it’s always worth repeating something, especially if you’ve found someone who can express the idea more articulately than you can.

Joseph Romm of the Center (sic) for American Progress (centrist American think tank) writes eloquently on the reasons why hydrogen fuel-cell powered automobiles are a dead-end and that there are better alternatives:

More than 95 percent of U.S. hydrogen is made from natural gas, so running a car on hydrogen doesn’t reduce net carbon dioxide emissions compared with a hybrid like the Prius running on gasoline. Okay, you say, can’t hydrogen be made from carbon-free sources of power, like wind energy or nuclear? Sure, but so can electricity for electric cars. And this gets to the heart of why hydrogen cars would be the last car you would ever want to buy: they are wildly inefficient compared with electric cars.

I’ve never been entirely clear why investors, boffins, and the popular press like hydrogen fuel cells so much. And why the insist on using the buzzword the hydrogen economy, implying that this is capable of replacing our current oil-based transport setup. Is it just because the cars themselves don’t emit any carbon dioxide during operation? I don’t know, but I suspect some people, including automakers Honda are in for a nasty shock.

Potentially huge Brazilian oil deposits good news for fuel supply

1 Comment

An oil platform in Rio de JaneiroWith oil prices again reaching historic highs today of more than $113 a barrel, there are unofficial reports that a massive oil reserve may have been found in the ocean off the coast of Brazil. The drilling company involved, Petrobras, has yet to announce confirmation but National Petroleum Agency President Haroldo Lima said the reserve could have as much as 33 billion barrels of oil, making it the largest find in decades.

Petrobras played down the reports, with the second well drilling into the deposit yet to break through the salt layer under which the oil could be expected. However with biofuel production threatening food shortages in Latin America and the rest of the world, a big oil find in Brazil would come at a much needed time for fuel security.

The world’s second largest producer of oil, Russia, had falling production in the first quarter of 2008, with industry officials ‘gloomy’ about the prospects of even staying at current production levels. Global production has plateaued in recent years, with growth in production in Angola and Russia balancing falling production elsewhere. More finds like the one in Brazil, as well as increased efficiency in using the oil produced will be needed if global production begins to decline.

The Energy Island

3 Comments

Combining multiple methods of alternative power generationThe Oil Drum Australia has a great post this week about tidal power construction all across the world, including the attractive ‘Energy Island’ concept pictured. The article talks about tidal, ocean current and wave projects from the UK, US, New Zealand, Taiwan and Canada, amongst many others. The UK could potentially derive 25% of its power just from wave energy, not to mention its huge resources of tidal power in the Severn Estuary and on the coasts of Scotland. Also discussed is OTEC (Ocean Thermal Energy Conversion), which creates power from the heat differential between warm surface water and cold deep water.

In other news, Oil has never been higher priced in history than it is today, at $102.08 a barrel. Looks like we’re going to need a lot of this alternative energy supply. One of the projects mentioned at the bottom of the Oil Drum article is for floating islands of power generation producing hydrogen to fuel passing ships. Neat.
