The ANU Energy Change Institute Launches Website

The Energy Change Institute at the ANU is launching its website. As you can see from the website, the Institute brings together researchers from many different areas across the ANU from artificial photosynthesis to energy economics and policy and from enhanced oil and gas extraction to solar photovoltaics. Several of my colleagues in the Crawford School and Research School of Economics are

Synthesizing Diesel Fuel Using Cyanobacteria

A US firm called Joule has bioengineered cyanobacteria to secrete diesel or ethanol. The picture above is from the Washington Post version of the story and shows panels containing the organisms. But as is the case with other recent inventions the economics are not yet clear. The company claims they could produce fuel at $30 per barrel - a third of the current price of crude oil. They also claim

Cold Fusion Again?

I still remember how excited I was back in 1989 when the original claim of achieving of cold fusion was made. I remember sitting in the communal kitchen where I lived in North London and excitedly telling someone about how important it might be if it was real. They were surprised that I was excited about this one news item. Tiananmen Square and the fall of the Berlin Wall were to come later that

And Today a New Lighting Technology...

Another new technology to report on: http://www.technologyreview.com/blog/energy/26230/?ref=rss">lighting using cathode ray tube type technology. The claim is that it is cheaper than LEDs and safer than fluorescents.

Artificial Photosynthesis

Interesting innovation - solar furnace that uses sunlight to convert carbon dioxide and water to carbon monoxide and hydrogen. These are necessary inputs in the Fischer-Tropsch process of synthesizing liquid hydrocarbons. So, this is effectively artificial photosynthesis. At the moment, the efficiency is no better than plant-based photosynthesis and the reactors would be more expensive than

Porsche Develops Hybrid Technology

I blogged about the development of hybrid cars by BMW and Mercedes when I was visiting Munich. My point was that fuel economy standards were forcing luxury car makes to adopt hybrid technology. I saw this as a route to wider adoption of hybrid technology in mass-market cars. Non-luxury hybrids seem so far to only appeal to "green consumers" willing to pay a premium for lower fuel consumption.

Will the Adoption of Solid State Lighting Lead to an Increase in Energy Use?

The Economist discusses an article in Journal of Physics D: Applied Physics by Tsao et al. on the effects on energy use of the adoption of solid state (i.e. LED) lighting (SSL) on global energy use. The Economist argues that it would be better to keep incandescent bulbs as a result. This seems a bit crazy. The literature on the rebound effect suggests that for energy saving innovations for

Role of Fuel Economy Standards in Effecting Technological Change

I was fascinated to learn yesterday that Mercedes has paid the US government $300 million in fines due to violating the CAFE standards. As fuel economy standards continue to rise manufacturers will need to find innovative ways to reduce the fuel consumption of their luxury and sports models in order to end up with acceptable cross-fleet mean fuel consumption figures. The interesting thing is that
