Biofuel production from forests increases CO2 emissions

Biofuels are gaining more and more ground as a replacement for fossil fuels. Especially because they are carbon-neutral or even reduce atmospheric CO2, but also because of the need for energy security and oil price spikes. In their search for … Continue reading

Biomaterials should be more important than biofuels

When talking about a biobased economy, most people think biofuel. And who can blame them, since gasoline alone is good for about half of global petroleum use? A transition from petroleum to biomass as a source for fuel would put … Continue reading

Hydrogen fuel produced from sunlight and safely stored

Hydrogen has long been commended as a clean and efficient alternative to gasoline, but so far it hasn’t really been able to live up to expectations. Mostly because it has to be derived from non-renewable sources like coal and natural … Continue reading
