Texas biodiesel efforts continue despite controversy over pollution
The only problem is that the Texas environmental regulators are concerned about NOx emissions with biofuels. An EPA study shows increases but the biodiesel community says other studies find no such issues.
The Texas Commission on Environmental Quality is giving biodiesel producers until the end of next year to prove the fuel can meet state air-quality standards. Biodiesel producers are in limbo, however, as investments may stall until approval is given.
Catch-22: there are chemicals that can lower NOx, but the producers say the additives will boost the costs. Looks like the conflicting studies need to be resolved in a hurry.
