Algae biodiesel production cost, thrice as costly as petroleum 20
The cost of producing biodiesel from algae is currently 52.3 Euros per gigajoule of energy, compared with 36 Euros for rapeseed and only 15.8 Euros for oil.
Wesseler has factored in the high costs of algae reactors based on figures from current, especially American, algae processors.
'Those facilities are not the most modern and efficient', he says.
'In the past year, the conversion of algae into biodiesel has become more efficient and, therefore, less costly.'
Wageningen University, part of Wageningen UR, is the only university in the Netherlands to focus specifically on the theme healthy food and living environment. Environmental economist Justus Wesseler PhD is a Professor at Wageningen University.
Wageningen University is part of Wageningen UR (University & Research centre). The university works together with research institutes and Van Hall Larenstein University of Applied Sciences, also part of Wageningen UR.
If biodiesel from algae were to be competitive with other biofuels, the productivity of algae reactors would have to grow annually by at least three to four percent more than the productivity of other bioreactors over a stretch of fifteen years, says Professor Wesseler.
Wesseler gives this a fairly high probability of success.
'Wijffels and Barbosa see many ways to improve the production process. The conversion of rapeseed and other crops into biofuels is already at a more advanced stage compared with that for diesel from algae.
Upscaling the technology can also lead to big cost reductions.' If oil prices were to rise again too, a point will come when biodiesel from algae becomes cheaper than biodiesel from oil.
Provided that the government and the private sector keep investing in developing algae technology, adds Wesseler.
