Ethanol from Biomass: A Sustainable Option?

The Promise of Cellulosic Ethanol I have mentioned a couple of times the research I was involved in during graduate school. I have provided a couple of links (under “Links”) that describe this research in detail. Briefly, we were trying to turn biomass (switchgrass, corn stover, wheat straw, and municipal solid waste) into ethanol and various organic acids and ketones. Biomass consists of many organic components, but it is primarily the cellulose component that gets turned into ethanol, hence the term cellulosic ethanol. Cellulosic ethanol has two major advantages, and one major disadvantage over ethanol from grain. The first major advantage is that large fossil fuel inputs in the form of fertilizer are not required to produce the biomass. Therefore,… Continue»

Improving the Prospects for Grain Ethanol

In my previous essay, you probably gathered that I am not enamored with grain-derived ethanol. I consider it to be a kind of fool’s gold that looks nice and shiny to the general public. Considering the magnitude of the subsidies as I showed in the previous essay, the industry is nowhere close to being able to compete on a level playing field. If the industry is to survive, you can count on multibillion dollar handouts – or mandates – as far as the eye can see. As I write this, the spot price of ethanol is $2.43, versus $1.74 for mid-grade gasoline. Considering that most people don’t buy mid-grade, you can knock another dime or so off the price of… Continue»

Grain-Derived Ethanol: The Emperor’s New Clothes

Energy security. Homegrown fuels. Better markets for our farmers. And by gosh, it’s good for the environment. Sounds good, doesn’t it? Where do I sign up? However, the truth behind grain-derived ethanol is masked behind half-truths and myths promoted by a very powerful lobby on behalf of agricultural and ethanol interests. This is one of the biggest scams in operation today, enabled by politicians who fear the political power of that powerful lobby. I will dissect some of the claims in this essay, and show why grain-based ethanol is a huge misallocation of resources. First, what do I know about ethanol? I grew up on a farm, and my family still farms. I wanted to help farmers and the environment,… Continue»

My Resume

Updated 3/23/2015 Or if you prefer, my CV, which has more specific details on patents and professional accomplishments. In a nutshell, my passions are energy, the environment, and sustainability. I have worked on a wide variety of energy projects – both conventional and renewable – in several different countries. In my spare time I write about my passions primarily in an attempt to influence the discourse over our energy policy. A major interest of mine is to find ways to better utilize the waste biomass throughout the world that is currently burned or land-filled. ——————————————————– ROBERT RAPIER Location: Hawaii My personal Email CHIEF TECHNOLOGY OFFICER Global Management Executive and published author with a track record of coaching internationally diverse, multidisciplinary… Continue»
