Fuel for thought

Two recent reports pour a fair amount of cold water on the biofuels issue. If you recall, I’m not convinced they are the answer to long-term sustainability, but can have some temporary benefits while the search for a solution to the two-fold problem of oil shortage and global warming continues. The first, published by the UN, starts by acknowledging the necessity of ending reliance on oil for energy needs, particularly in developing nations. But a sharp warning on the dangers of monopoly, further environmental damage in the rush to procure more agricultural land, water demands quickly emerges. Rather a dampener on proceedings. The second report was commissioned by the Co-operative insurance society (an online copy of which I’ve yet to look for) seems to be in general agreement, judging by the BBC article.

They make good points to ruminate on. Perhaps after Manic May is over.

Coconut Cars

The story on cars fueld by coconut oil on an island in Papua New Guinea sparked a lively conversation in our household about the various alternative fuels on trial all over the world. Coconut oil sounds like the perfect sort of island-based fuel that seems to make environmental sense. Apart from the lower concentration of sulphur dioxides, nitric oxides and general soot, not having diesel delivered to the island by diesel-burning ships also makes sense (apart from the fact that the ships are still necessary for trade and transport). While coconuts are probably not in as plentiful supply on tropical islands as us continental types would like to think, they do have more coconuts than they can use in terms of juice, meat, soap and cooking oil. This begs the question of just how many coconuts one would have to gather to fuel a moderately low mpg vehicle. And just how much energy is expended on processing the coconuts? Can the processing plants be run on coconut oil too? Can electricity generators be adapted to use it? How long does processed coconut oil last (the cooking stuff tends to ming after a while if not properly stored)? What nasty additives have to go into the mix to get it to burn nicely in infernal combustion engines?

And all these questions got me to thinking just how negative we were being. True, as part of our job, we think critically: always looking for flaws in the data or hypotheses, poking around to ensure data is not misinterpreted, second guessing. All without meaning to be cynical. Just careful.

And it also got me thinking of how news of alternative fuel is always met with a few “so what?”s from the commentators. They have a point: there is absolutely no way that the USA could ever grow enough corn to fuel all their cars with ethanol1; no way that every little Pacific island could be completely self-sufficient on coconuts for oil; no way that Asda’s recycling of cooking fat in their trucks could inspire every householder in the UK to rob their local chippy. But they also miss the point that every small number of converts means that the trend for increasing oil-driven energy consumption is ever so slightly diminished. Every solar panel installed, every wind turbine that gets past the “Conservative Communities Concerned for Conservation of their Beautiful and Historical Landscape”, every wave harvester makes a difference, however small. Slowly, one small appliance2 at a time, we can slow down the growth of energy consumption. It’s accurate to point out that demand for energy is still growing. The alternative energy sources will not fix that problem. That is up to individuals and governments to tackle. It may hurt attempts to invest in alternative energy if we keep lumping them together. For it to work, it must be economically viable, even if the early stages are heavily funded by rich governments.

It also seems fairly obvious to a numpty like myself that it is to the interest of growing super-powers to invest heavily in research in this area now. Countries like China and India already have enormous energy demands, which will no doubt increase. Peak oil may be upon us (although it is still heavily debated, but let’s not go into that now). Unless China and India (and any other super-power I don’t have the precogniscent ability to see) have ever-lasting supplies of coal or oil, or can twist OPEC’s arm, they will need to not just use current alternative energy sources, but drive the development of new ones. Which they probably are already doing (apart from nuclear power, that is; but let’s not get into that now either).

This didn’t start out as a rant, though it has turned fairly incoherent. I guess my point was that it is easy to be a nay-sayer when it comes to the real benefits of alternative energy sources, be they fuel for vehicles or to provide electricity to needy bloggers. But as the hegemon known as Tesco likes to say, every little helps.

Incidentally, this news comes as I’ve finished reading a recent LA Times Book Festival purchase: The Sex Lives of Cannibals, by J. Maarten Troost3. I wonder if the inhabitants of Kiribati (pronounced Kikibas4, according to Troost) have the technological ability or drive to consider adopting coconut oil as a fuel? Or failing which, export their copra to their Pacific neighbours in exchange for some food that is not fish.

1 Speaking of which, doesn’t the harvesting, transport and processing of the corn crop suck up a whole lot of energy in itself? Oh me oh my, how easy it is to be cynical.

2 e.g. the iPod. Oh, we’re back on the greenness of Apple again are we? Incidentally, this reminds me that I desperately wanted a Solio before I left for LA because I thought there would be enough sunshine here for it to work. But they were out of stock then. Would it be naughty to buy one now and have it shipped here? Even more naughty than charging the iPod on the mains every other night?

3 And speaking of the book, this gives me an opportunity to have a photo in the post. Haven’t you missed my awful photography?

Biodiesel in Scotland

From BBC news: Green biodiesel production starts.

Finally, Argent Energy are ready to roll with cleaned-up chip fat (and other cooking oils) as biodiesel. While biodiesel by no means solves the problem of increasing carbon dioxide levels, it will help alleviate our dependence on fossil fuels, which must run out at some point. [It cannot be stressed enough at this point that biodiesels will NOT help reduce the damage we do to our atmosphere. It's merely a stop-gap, and cars using it will still release carbon dioxide. Fewer of the other pollutants, and less dependence on fossil fuels and the damage we do to the environment to get at it!]

But this will not the perfect biodiesel solution I would have liked. Argent are planning to blend their biodiesel with mineral diesel, and call it “Bio-plus”. Now, that seems like quite a cop-out to me, and I know quite a few other people who will be disappointed to hear that this won’t be marketed as a purely recycled fuel. Sundance Renewables in Wales are a co-operative that produce and supply 100% recycled biodiesel to Welsh businesses. To be fair to Argent, they’re planning to refine 25k tonnes a year, have probably put quite a lot of investment in complex machinery (it doesn’t have to be that complex on a small scale), and must answer to shareholders etc.

Prior to recent commercial developments, there were stories in the news about some Welsh folk using Asda’s cooking oil in their cars, with one of them (John Nicholson, an environmentalist) having gone out of his way to recycle chip fat and contacting Customs to pay duty on what he put in his car. Following the media hoo-hah, Asda also announced that some of their fleet would use fat used to roast chickens. :)

And let’s not forget that diesel engines were first invented by Rudolf Diesel expressly to use vegetable oil. He mysteriously disappeared on a ferry crossing the Channel… To end on a sober note, George Monbiot had a wee rant last year in the Guardian about the endemic blindness to the downsides of switching to biodiesel on a massive scale, namely the commercial growth of oil-rich crops over that of food crops. Naturally, I hope his worst-case scenario does not come to pass, where political idiocy prevales over common sense, and the nutritional needs of the poor are neglected in the pursuit of alternative fuels. But you never know with our money-hungry society.
