The corn-ethanol carbon balance argument again

There is an interesting video on Climate Central about the amount of carbon dioxide produced when ethanol is made from corn grown in the mid-West of the US. Hard to tell who is right in this debate (if any one is) the different premises are all important and few people seem to try and compare […]

Ensus new website outlines paradox at heart of biofuel from food processes

Ensus new website, for me outlines the paradox at the heart of the biofuel from food processes. If you take food out of the food chain then there’s less to eat. It really is that simple even if you’re using animal grade wheat. Animals cannot surely live on just protein and bran? With a minimum […]

Corrected: Ineos to use municpal waste and algae to make ethanol

Corrected:This article originally appeared with the headline Ineos goes down the Fischer Tropsch route to ethanol from municipal waste. The process will use algae to convert carbon dioxide and hydrogen into ethanol not a chemical catalyst. This has been corrected in the first paragraph. Ineos is to use municpal waste and algae to make ethanol […]

Ethanol without the microbes

Interesting comment from David Benson, a bit off topic,  but bang on the money about alternative technologies. This has a lot of things I like, especially the Fischer-Tropsch Synthesis plant which uses hydrogen from electrolysed water, (electricity generated by wind) and smokestack carbon dioxide to make ethanol. It would be interesting to see how Doty […]

A really bad idea

I’ve just come across a pretty bad idea on a site which claims to be about popular science… popular hogwash if the rest of it is up to this standard. As reported idea revolves around converting carbon dioxide from smokestacks to baking powder. Baking powder works by releasing carbon dioxide in the oven when it […]

Clean as you go and there’s more potential biofuel

Clean as you go and there’s more potential biofuel, three inventors from North Wales have developed a box that can capture the exhaust gases of cars so they can be used to grow algae. There are a number of technical difficulties that need to be overcome. Firstly, how do they stop the exhaust gases choking […]

BioAmber may help make ethanol production greener

BioAmber has a process that may may help make ethanol production greener at a new plant that will take carbon dioxide from ethanol production and make a bio substitute for oil in petrochemicals. BioAmber, is  a joint venture between Diversified Natural Products (DNP), a U.S. based biotechnology company, and French based Agro Industries Recherche et Development (ARD)) announced […]

Biodiesel from flue gas emissions

You remember that thing I picked up a few days ago about people using algae to make biodiesel from flue gas emissions? At the time I was a little sceptical about the idea,mostly because I

Biodiesel: what’s the rationale?

Why bother with biodiesel? The European Biodiesel Board published a list of questions and answers in July, in response to the European Commission, which asked for comments as part of its plan to modify
