Gas 2.0

A coal fired power-plant in Oregon has started a pilot project to curb pollution by using algae to harvest greenhouse gases and make fuel and other useful products.

The power plant in Boardman, Oregon, is the state’s only coal-fired facility — and also the the state’s largest single emitter of carbon dioxide. To deal with this problem, Portland General Electric and Columbia Energy Partners have started a pilot project to turn the otherwise nasty emissions into biodiesel, ethanol, and even livestock feed.

One Ford factory in Oakville, Canada has created an innovative process to capture harmful gases from their vehicle-painting facility and safely turn the fumes to electricity.

The paint fumes contain volatile organic compounds which act as greenhouse gases and pollutants. Typically, these gases would be incinerated, which while better than leaving the VOC’s alone, still produces excessive amounts of carbon dioxide and nitrogen oxide. Ford has developed a much cleaner process to dispose of the gases.

As the global market for biofuels heats up, much of the demand for biodiesel is being satisfied by clearing virgin rainforests to create oil palm plantations. But, as it turns out, these plantations are an awful substitute for rainforests.

A group of British, German and Danish researchers has found that the biodiversity of oil palm plantations is far lower than that of tropical rainforests and that no amount of plantation management changes could ever possibly make them come close to replicating rainforest diversity.

This is a guest post by Meg Hamill who works at the Environmental non-profit LandPaths, in Sonoma County, California.

Leaders in the aviation industry join together, committing to bring sustainable practices into their fuel supply chain.

For those of us who have taken a flight recently,  it’s obvious that the airlines are in trouble.  Who ever would have thought that we’d be paying extra for a pillow?  Or an aisle seat?  With the rise in oil prices, many airlines are seeking out creative ways to stay afloat.  Some of these companies are going straight to the heart of the issue, and beginning to investigate a more sustainable fuel supply.

While Boeing has been researching biofuels in the aviation industry for some time, last week’s formation of a new collaborative group ratchets up their commitment to the issue, and brings some key players to the table.

Boeing joined Virgin Atlantic Airways, along with eight other commercial airlines to establish the Sustainable Aviation Fuel Users Group.  The group is committed to accelerating the development of sustainable biofuels for use in the commercial airline industry.  Honeywell’s UOP, a refining technology developer, is also part of the group.

The European Union decided pull of the accelerator of its fairly ambitious bio-fuel plans for the future.  Nearly two thirds of the European population feels that climate change is a big issue, yet the EU itself is not planning on holding up its end of the bargain.

The 1990’s were the host of many great fads. Furby, Tamagachis, string theory, the examples are as numerous as the many incarnations of Prince. Fast forward to 2008, and it seems that America’s fads are finally becoming practical. Hypermiling is the new hoola-hoop, and it’s even more convenient because there is more than one way to do it. While some prefer drafting and coasting in neutral whenever possible, most drivers just watch their tachometers.

Enova Systems and IC Corporation have delivered a plug-in hybrid diesel electric bus to Denali National Park for use in carting visitors around the pristine wilderness.

The bus (similar to the one pictured above) has a GVWR of 27,500 pounds, carries up to 38 passengers and uses up to 70% less fuel than a similarly equipped conventional bus — so if the bus got 10 mpg with a conventional engine, it could get 30 mpg using Enova’s hybrid system.

According to an article in the Jakarta Post, an official from the Indonesian government has spilled the beans on Samsung’s plans to invest up to $1.63 billion dollars in what’s sure to be a controversial acquisition of land for growing oil palms and construction of a biodiesel plant in Indonesia.

The current rate at which biofuels are falling out of favor is largely founded on biased ideologies, which have been shaped by widespread political and corporate agenda-pushing from all sides of the fence.

But first, a digression.

Part 1: When an egg was just an egg

I remember a time when an egg was just an egg. Nobody argued about that. It was a blissful time. Yet, for all its strengths, it was a fragile time held together by unsupported conclusions and limited knowledge.

Plug-in hybrid, all-electric or fuel cell? Car-makers are hedging their bets on what will emerge as the next generation engine technology of choice – now it seems another alternative approach could well be set to enter the mix. Scottish engineering firm Artemis Intelligent Power has tested a hybrid system that it claims can cut carbon emissions by 30%, with the added advantage that it is better suited to inter-urban journeys than conventional hybrids like the Toyota Prius.

In common with other hybrids, the system employs a regenerative braking system that stores energy as the vehicle slows down, and feeds it back into the engine as it accelerates. The key innovation is that instead of storing the energy in a battery, the new system stores it in a hydraulic accumulator. Read the rest of this entry »

In a perfect example of why Cliff’s Notes don’t substitute for reading the whole book, the method by which Paul McCartney’s new luxury hybrid was delivered to him has ruined any environmental gains that might have been made by driving a hybrid in the first place. Indeed… his brand new Lexus LS 600h hybrid was flown to him by cargo plane. Questions of whether or not a 5.0-liter, V-8, 19 mile per gallon luxury behemoth really exemplifies the spirit of a “hybrid” aside, the judgment involved in shipping cars by airplane is enough to cringe at.

Doing some of my own napkin calculations (below) I came up with a fuel efficiency for the 5,966 mile trip from Tokyo to London of 4 mpg. That’s assuming the cargo plane burned 5 gallons of fuel per mile and there were 19 other cars in the plane. I’m not so sure there were 20 cars on that cargo plane, but we’ll give him the benefit of the doubt. What this means is that the former Beatle’s new Lexus hybrid got 4 mpg for the first 5,966 miles of its life without ever starting up or even getting the chance to enjoy its V-8 glory on the open road. What a shame.
