The search for a new fuel source for cars continues

Excerpts:

1. Almost any organic material can be converted into energy. Hawai‘i’s potential comeback crop, sugarcane, whose fibers, affectionately called bagasse, are a form of organic waste which can be fermented into ethanol, an alcohol fuel. Other potential “cellulosic” materials for ethanol production include sawdust and wood waste, rice hulls, rice straw, corn, wheat, soy beans, potato skins, sugar beets and yard clippings.

2. Unfortunately, alternative fuels, or clean technology, still cost more per gallon to produce than good old fossil fuel.

3. With new algae technology, a barrel of biodiesel would cost $32 to $75 per barrel, still too high to compete, and a couple of Hawaii scientists are experimenting with algae as the feedstock.

4. Waste oil, free from restaurants, is another low (no?) cost feedstock. But scalability is an issue with waste vegetable oil (WVO)

5. Scientists should look into genetically modified crops for alternative fuel options.

6. Hybrid cars have continued to develop better technology and made in-roads into the car market. Some companies even offer additional plug-in kits to popular hybrids, such as the Toyota Prius and Ford Escape, for more alternative power.

Personalities & organizations mentioned: Dr. Barry Raleigh, a researcher at the Hawaii Natural Energy Institute and managing partner of HR Biopetroleum, a start-up company working to manufacture algae-produced biodiesel.

Hydrogen – a truly sustainable transport fuel?

Hydrogen – a truly sustainable transport fuel?
David Harta - A White Paper

Abstract of the white paper

Imperial College Centre for Energy Policy and Technology, RSM Building, Prince Consort Road, London, UK

Transport energy, particularly that derived from fossil fuels, is causing increasing problems worldwide. Hydrogen as a transport fuel offers solutions to many of these issues. Produced from renewable resources, hydrogen could cut greenhouse gas emissions to zero, and the use of some fossil sources could even reduce emissions. Air quality and noise problems would also be addressed. Although developments are underway, and many countries see hydrogen as part of a sustainable energy future, implementation is being hindered by social and economic considerations and immature technology. To ensure that expectations are met, support is needed from policy makers, industry, and the public.

Technologies for a Greehouse Planet - Alternative Energy Explored

You are at: Oilgae Blog; see also: Oilgae - Oil & Biodiesel from Algae



Came across an interesting research paper by Martin Hoffert of New York University.

In this interesting paper, he discussed greenhouse effect, carbon sequestration rates and related issues. He goes on to explore just what types of energy alternatives we have in future - hydro, wind, geothermal, biomass, terrestrial solar, ocean thermal and tides, fission (u-235 reactors and breeders), fusion (D/T, D/3He fuel cycles & space power (LEO & GEO orbits, lunar power systems)

and looks at the challenges faced by any carbon-free technology to deliver the massive amounts of power that will be required by 2050...

In the long run, he says, "expansion of the human experiment to space may be the only
way to resolve the conflict between ever-increasing economic growth and a
sustainable environment on planet Earth (Myers and Simon, 1994; Lewis,
1996). Peter Glaser's geostationary orbit (GEO) solar power satellite (SPS)
studied as the NASA/DOE SPS Reference System of the 1970s was an early
conceptual step toward moving terrestrial energy production off the planet
(Glaser, 1968)."

Interesting paper, you can read it here (PDF format, quite a long one, 25 pages)
