Planet Energy

The 19th and 20th of November the Swedish Energy Agency held the yearly research congress.

The passed year with the initial oil price rally and with the financial strain we have been experiencing the expectations on new technologies were higher than ever. A lot of emphasis was put on energy management.

I got the opportunity to give the last presentation the first day and the hybrid topic was thus much appreciated.

Maria Grahn from Chalmers spoke about the preferred options for sustainable transports in a distant future, year 2030-2100. A conclusion was that the future technology development will be decisive for the preferred choice, from a cost perspective. Depending on the price of future batteries or fuel cells for example they electrical vehicles or fuel cells may become competitive. Or, as we discussed after the presentation sustainable fuels such as biogas may become competitive depending on the availability of biomass.

Some years ago I collected some information to understand the availability of biomass wastes in relation to the needs of the transportation sector.With reservation for not having a peer review, I got the following result:

EJ stands for Exa Joule (1.e. 10 to the 18 Joule)

Considering that buses are almost ten times more energy efficient than cars. It seems that we can still take large steps towards a sustainable society by combine energy management, smart technologies and improved management of the biomass wastes.
