Hydrogen is rising as an eventual clear various choice for fueling vehicles however the feedstock used to provide it — by steam methane reforming, utilizing coal or with photo voltaic panel-generated electrical energy — impacts its carbon impression.

For now, a number of completely different colours are used to determine every course of, with black being the dirtiest and inexperienced the cleanest. Hydrogen engine maker Cummins Inc. wish to see a special gauge.

“We’re conscious of the trade jargon on colours. They don’t seem to be customary, however they’re methods to take that [carbon impact] and put it into on a regular basis dialog,” stated Jim Nebergall, basic supervisor of Cummins’ hydrogen engine enterprise.

“It’s not apparent what the appropriate answer is there for a way we discuss it and monitor it,” he added. “I believe it will be good for the trade to give you only a carbon-intensity measure.”

However Cummins believes the selection on utilizing a hydrogen gas with any of the assorted carbon intensities in its historical past is as much as the tip consumer.

“They put the gas in. It’s the identical hydrogen. It’s simply how was it created. And that’s actually going to be as much as the gas corporations, and what they’re delivering to the pump. We wish to see inexperienced,” Nebergall stated.

As for efficiency, he added, an engine or gas cell received’t have the ability to inform the place the hydrogen got here from, it’s simply gas.
