Bio-Based Ideas

This is still from the SD-CAP Symposium. Another talk I wanted to summarize was Professor Stephen Mayfield's talk titled "Where we are - where we are going" The presentation slides can be found at the following location for anyone interested: http://algae.ucsd.edu/documents/SD-CABsymposiumMayfield.pdf Professor Mayfield’s talk was more of an overview talk meant to introduce the audience to the topic of algal biofuels. It could be divided into 2 parts: the problem, and the solution. The Problem Professor Mayfield started by making the point that between 1900 and today energy has been a rapidly growing market reaching $5.8 trillion today from just $ 0.4 billion. The future energy market is predicted to double in value within just ten years. There is an interesting correlation between energy use and wealth of a nation. The United States according this chart is one of the wealthiest nations in the world while also using proportionally more resources. The future growt...

In the last focus section , we discussed how algae can be used to treat waste waters and mitigate CO2 in the process. Today's post will explore how algae can be used for energy generation. As already mentioned in the last time, biofuels have become very visible as of late due to environmental, economical and geopolitcal reasons. If at the heart of traditional biofuel generation lies in the creation and decomposition of biomass, then it would be easy to substitute corn or other less controversial land-based plants with algae. Although a lot of attention is paid to the use of algae in biofuel generation, and this article also mainly focusses on this aspect, it should be noted that algae can also be used to generate electricity by direct combustion of the biomass. Plans for these kinds of schemes are already on the way in Venice and a few other European locations [1]. Algae and Biofuels What happens to the biomass after it has been created depends on the type of biofuel that is de...
