UCLA, ARB, WVU measure on-road particle numbers for heavy-duty diesel and CNG trucks in California

Green Car Congress

In a new study, a team from UCLA, with colleagues from the California Air Resources Board (ARB) and West Virginia University, measured total particle number emission factors (PNEFs) from six newly certified heavy-duty vehicles (HDVs) powered by diesel and CNG totaling over 6,800 miles of on-road operation in California.

Alabama Project Testing Potential for Combining CO2 Storage with Enhanced Methane Recovery

Green Car Congress

The final phase, the development phase (2007–2018), will conduct large-volume carbon storage tests. The validation phase (2005–2010) generally involves small-scale field tests and includes the Black Warrior Basin CO2 Storage Project. The National Energy Technology Laboratory manages the partnership program for DOE’s Office of Fossil Energy.
