Multicomponent catalytic system efficiently converts carbon dioxide to methanol

Green Car Congress

Inspired by naturally occurring processes, a team of Boston College chemists used a multi-catalyst system to convert carbon dioxide to methanol at the lowest temperatures reported with high activity and selectivity. The first catalyst converts carbon dioxide and hydrogen to formic acid, which is then modified by a second catalyst to form an ester, incorporating an alcohol additive and producing water.

Celeroton introduces new 7.5 kW fuel cell converter

Green Car Congress

Celeroton is expanding its portfolio of fuel cell converters. With the launch of the improved power electronics converter, CC-550-7500 , operating compressors up to 7.5 kW of drive power (at 300 VDC converter input) is now possible for fuel cell stacks of up to 75 kW. If the fuel cell then produces sufficient power, the converter switches to the high-power input (range of 100-550 VDC) to operate the compressor directly from the fuel cell.
