High-tech, Clean-burning Energy

If you have been reading the recent posts here in Comments About Responsible Energy, you know that we have been talking about environmentally responsible energy consumption and the effective use of fossil fuels. This posting comes to us from a member of our Energy Counsel: Dennis Avery. It has been a while since he has sent us a contribution, but this one is a perfect fit with the theme we have been looking at.

Additionally, we've addressed an energy gap--the time between the desire to kill the current energy sources and when the next generation is available--and this posting concludes with a comment on an energy gap.

Here, we look at some new technology that makes sense. While the concepts presented here are still in the research phase, it is exciting to see that is being done to generate energy at a lower cost and with less pollution—that is responsible energy!

Lots of innovative things are being done in the field of energy. Read on and tell us what you think!

Turning Tar Sands Into Natural Gas With Bacteria
Scientists said recently in the journal Nature they can radically speed up the underground bacterial fermentation that turns Canada’s tar-like Athabasca sands into natural gas at far less cost and with far less environmental pollution. This is huge global news because the world has about six trillion barrels of such heavy oil, more than 20 times the proven oil reserves in Saudi Arabia. They’re focused in Canada’s Athabasca, in Venezuela’s Orinoco tar belt, and in the oil shale of the U.S. Rocky Mountains. All may be economically recoverable with bacterial refining.

Dr. Steve Larter of the University of Calgary says understanding how anaerobic bacteria ferment heavy oil into clean-burning methane underground opens the door to recovering the gas from deeply buried oil sands. “The main thing is you’d be recovering a much cleaner fuel,” he says. “Methane is, per energy unit, a much lower carbon dioxide emitter than bitumen.”

A separate family of microbes that produces CO2 and hydrogen from partly-degraded oil offers a way to capture the CO2 from the tar sands as methane.

Larter’s research team combined microbiological studies, lab experiments and oilfield case studies to demonstrate the anaerobic degradation of oil into methane. The findings offer the potential of “feeding” the microbes and rapidly accelerating the gas production process. Says Larter, “Instead of 10 million years, we want to do it in 10 years. We think it’s possible. We can do it in the laboratory. The question is can we do it in a reservoir? ”

No longer would huge diesel shovels have to dig up three tons of sand for each ton of heavy oil recovered. Nor would refiners inject expensive steam to liquefy the heavy oil so it can flow to the surface. With bacterial refining, the tar, and the contaminating sulfur, can be left deep underground—along with most of the sand.

The oil-eating bacteria have been used for some years to clean up contaminated soils and lagoons near oil refiners. Lab results have been encouraging, and the team expects to do field tests as early as 2009.

At almost the same moment, a Penn State professor said drilling newly-feasible horizontal gas wells across the Marcellus black shale in northern Appalachia could earn the U.S. a trillion dollars worth of additional clean-burning energy. The rock deposits run from southern New York westward through Pennsylvania into West Virginia and Ohio.

Dr. Terry Engelder says the vertical fractures in the Marcellus shale can’t effectively be tapped with vertical wells. A horizontal well costs three times as much, but can collect gas from dozens of the fractures. He says the horizontal wells could bring in 50 trillion cubic feet of gas, the equivalent of a Super Giant gas field.

Eco-activists have been telling us we must renounce fossil fuels because “they’re nearly gone anyway.” However, the U.S. has centuries worth of coal that could be burned in “clean” high-tech systems. Bacterial refining and Dr. Engelder’s horizontal drilling provides other examples of high-tech energy. Cambridge Energy Research Associates predicted in June that world oil production would rise another 30 percent by 2017, with nearly half of the increase from uncon-ventional sources such as natural-gas liquids. Man-made global warming alarmists have failed to offer any cost-effective substitute for coal, oil and nuclear in base-load energy production Solar and wind power are costly and erratic. Biofuels take too much land away from Nature. The problem is to bridge the energy gap between today and some as-yet-unproven energy tech-nology for humanity’s future.
