Photobioreactors that Grow Algae to be Used to Make Biodiesel

 

The photo shows a conceptual rendering of a large scale photobioreactor used to grow algae. All that is needed is the sun, water, some added nutrients, the algae and carbon dioxide to produce about 10,000 gallons of bio-diesel per acre per year. Unused low value land is used or land adjacent to coal fired power plants where there is a supply of carbon dioxide from the flue gases of the plant. http://www.solixbiofuels.com/

 

Solid Oxide Fuel Cells (SOFC) go to Market

 

Several solid oxide fuel cell developers are moving through the pre- commercialization process to bring their natural gas fired combined heat and electrical power units to market in Europe. These units are designed for the average home and will provide all electricity and heat. By 2010 they anticipate the beginning of large scale market penetration and costs dropping to that of a typical high efficiency furnace. Pictured Topsoe Fuel Cells.

 

Concentrating Photovoltaics (CPV)

 

New PV cells that concentrate the sunís energy onto super high efficiency multi junction surfaces have efficiencies of three times current panels without relying on as much silicon as traditional cells. Several companies are competing for a place in this high growth area of renewable energy.  Pictured Suncube from Gold and Green Energy of Australia.

Cellulosic Anaerobic Digesters

Advances in both digester technology and the adaptation of high yield biomass such as Leucaena (at 25 tons per acre) enable the production of methane in large quantities very economically. Information on this process can be obtained at http://www.pipeline.com/~dglickd/CFR.html

 

Biomass Gasifiers

New mobile processes turn biomass into useful gases that can be used to generate electricity and a carbon byproduct that can be used as a fertilizer. The carbon from the atmosphere can be safely sequestered in the soil, a strategy for reversing global climate change. Pictured: mobile gasifier www.emergyenergy.com

 

Chevy Volt

Chevrolet announces that they will bring the Volt into production by 2010. A plug in hybrid, five passenger sedan about the size and cost of the Cobalt, that will achieve 175 miles per gallon overall. The battery bank will take the Volt 40 miles on electricity alone, the one liter flex fuel engine will charge the batteries which drive electric motors that are built into the wheels. The volt will get 53 MPG on the highway and have a range of 640 miles per twelve gallon tank

 

Dimethyl Ether (DME)

Synthetic diesel fuel can be produced from methane for under sixty cents per gallon if done on a large scale and being able to procure the methane for about $4 per million BTUs, which is possible by using either biomass gasification or anaerobic digestion of  biomass. DME is environmentally clean having no sulfur or particulates in the emissions. The ignition characteristics are superior to fossil diesel fuel. See http://www.greencarcongress.com/dme/

Ocean systems

A potential 20 MW commercial scale project off the coast of Portugal is now underway using the Pelamis system from Ocean Power Delivery of Scotland. Details can be found at www.oceanpd.com

 

  

Waste to Ethanol

A patented new process, developed at the University of Arkansas, promises to turn municipal solid waste (MSW), sewage sludge, used tires, plastics, agricultural waste, forestry waste and biomass into ethanol and electricity.
