What Price Biofuels?

Posted January 14, 2008 8:21 AM

The market for alternative fuels has become saturated as the boom-and-bust cycle takes hold, currently marked by oversupply of ethanol, tight profit margins, limited demand, and plummeting prices. Corn-derived ethanol has had little positive impact on energy markets and greenhouse gas emissions, and forecasts of a production ceiling are turning attention toward cellulosic ethanol. High costs are a barrier here too, but strides are being made toward one-step bioprocessing schemes and in engineering hydrocarbon-yielding microbes. Major technology breakthroughs are still needed to make a cost-effective transition to cellulosic ethanol production. What steps should be taken to ensure the economic viability of this biofuel supply chain?

The first step is to recognize the most readily available and usable biomass sources. Also identifying where they are before placing cellulosic ethanol plants.

Possible biomass sources are:

1.Corn stover, wheat straw, rice straw, and hulls, alfalfa, miscanthus, switchgrass, forest residue, peat, orchard residue,

2. Sewage and animal waste.

3. Possibly algae grown on site, if that technology is successful.

Plants should endeavor to use their own waste heat and the fuels they produce in their own processes and transportation.

Alternative Energies are also "Destructive and Evil" -- How can Alternative Energies be good when they require materials that originated from places that all environmentalists say are "evil and destructive"? Alternative Energies require "bad" materials for assembly, such as ceramics, carbons, and metals from Mines, and sometimes plastics and other carbon-based materials, which originate from Oil Wells and Coal mines that environmental groups say are all "evil and destructive". Even "natural" plant fiber materials require machinery and processing and transportation, which also require metals, ceramics, and carbon.

From where do we get the source materials for wind mills, fuel cells, hydrogen and other alternative energies? Most solar electric panels require ceramics and special elements, such as gallium, arsenic, germanium, etc., that came from mines and smelters. Windmills require metals (originally from mines and smelters). Passive and active solar ventilation and tubing for houses usually require metals and sometimes ceramics, which came from mines and smelters.

Environmental groups say that ALL Mining and Oil / Gas Wells are "bad" and "evil", even with full-scale reclamations and restorations. So how can we go to Alternative Energies when these requires materials that are not accepted by the Environmentalists?

Even fuel cells require materials originally from mines and smelters. Fuel cells have to have metals and / or ceramics for the containment, tubing, chemical reactions, etc. The cells, containments and associated materials use materials from mines and oil wells. Think about the engineered things used to even make hydrogen fuel get started for producing energy.

Look at the Periodic Table of all the elements of the earth. Hydrogen (H2) is a usually a gas. When hydrogen is used in a chemical bonding or mixture, it is usually released as a single free ion (H- or H+). Sometimes getters are used to store and transport hydrogen.

It is the cells and containments and associated materials that use materials from mines and oil wells. Go and look at the engineered things used to even make hydrogen get started!

To make Hydrogen "burn" and gain energy from it, there must be the chambers, vessels, tubing, connections and fittings. A characteristic of Hydrogen is that is can embrittle materials over time, especially certain types of metals and steels. Normally stainless steels or other specialty metals are used for most Hydrogen activities. These steels and steels are composed of iron and sometimes chromium and / or nickel to control any corrosion from Hydrogen and also prevent embrittlement as much as possible. The materials for steels ALL come from mines and smelters.

But how is hydrogen (H2 and the H ions) produced from water or other source materials? Either in the reaction apparatus and chambers of the cars or else in processing plants, both of which use metals and ceramics and plastics. If we get H2 from the air, we get it from gas separators which are composed of metals and other "bad" materials.

Environmentalist point to bicycles as environmentally-friendly transportation. To make bicycles, manufacturers must get materials that originated from mining operations (iron, molybdenum, aluminum, ceramics, etc.), oil wells and coal mines for Carbon and plastic materials, and sometime timber for wood. These materials are then processed in plants that also use products from mining and oil wells, and use electricity. How can this be "good" by any environmentalist's definitions?

Look at how many existing Wilderness Areas have abandoned oil / gas wells and also mining sites within their boundaries. Why is that permissible? How is it that reclamations of well drilling sites are either ignored or denied by the environmental groups now? There have been many private groups in the Pacific Northwest (like my grade school in the 1960's) that went out and planted trees, grass, and shrubs in the forests. We even saw some of the lumber companies replanting trees and shrubs. But apparently, none of those good efforts count in the mind of the environmental groups, as seen in recent publications and notifications.

Take a deeper look at what really is going on. Natural resources are needed for everything in our lives, even medical items and alternative energies. But when our natural resources are being closed up and as reclamations are either ignored or badmouthed, we are loosing the materials needed for our daily lives, even for the "nice" Alternative Energies. As a final note, my 1990 car gets the same gas mileage GPM as a modern hybrid car. Go figure.

In a publication from early 1992, the Sierra Club in Santa Fe openly announced that oil / gas well drillers were still using lead-based (Pb) lubricants. Never mind that the EPA banned their use several years before in the mid-1980s and that the drilling industry had already switched to biodegradable lubricants even before that. Never mind that law enforcement and the EPA later on checked for compliance in the industry. Also, there is new drilling technology, called Coiled Tubing, that allows certain types of well drilling operations from the back of a pickup, thus less impacts than the vehicles you drive. Why don't we don't hear that from the Environmentalists.

Are you familiar with the wilderness near Ruidoso, NM, USA? The wilderness boundaries "captured" some gold and silver / lead mines. The government threatened to sue the mine and claim owners with EPA Superfund status if they did not surrender the land for wilderness designation. Now how is it that places that are supposedly EPA Superfund sites can now be "wilderness" and untouched areas? The 1964 Wilderness Act specified that undeveloped, untouched, and natural areas were to be part of the wilderness areas.
