Colorless in addition to odorless, hydrogen can be an energy carrier. Indeed, hydrogen can both “store in addition to deliver usable energy,” according to the U.S. Department of Energy’s (DOE) Office of Energy Efficiency in addition to Renewable Energy.
The DOE adds in which hydrogen does not usually “exist by itself in nature” in addition to needs to be produced coming from compounds which contain the idea.
numerous sources — coming from fossil fuels in addition to solar to geothermal — can produce hydrogen using a range of methods. These include biological processes, thermochemical processes in addition to electrolytic processes, the DOE says.
When the idea comes to hydrogen, one of the big challenges can be producing the idea coming from renewable sources. “Right right now, most hydrogen can be made coming from fossil fuels,” Bruce Logan, coming from Pennsylvania State University, told CNBC’s “Sustainable Energy”.
“What we’re doing can be taking primarily natural gas, doing in which hydrogen in addition to then using in which hydrogen,” Logan added. “So we have benefits coming from using the hydrogen yet the idea still relies upon fossil fuels.”
While the idea may rely on fossil fuels at the moment, hydrogen incorporates a lot going for the idea coming from an environmental perspective. The European Commission, for example, has described the idea as an energy carrier with “great potential for clean, efficient power in stationary, portable in addition to transport applications.”
Penn State’s Bruce Logan was equally optimistic. “If we start with water, in addition to we electrolyse water in addition to … use some renewable energy source to do in which, then we can use the hydrogen in addition to … end up with water when we’re done,” he said. “the idea’s a water to water cycle in addition to we don’t need to burn all in which air like we do when we burn a fossil fuel,” he added.
The notion of “green hydrogen” can be an intriguing one, yet what exactly can be the idea?
“the idea’s hydrogen stemming coming from green sources,” Jorgo Chatzimarkakis, secretary general of Hydrogen Europe, told “Sustainable Energy” earlier This specific year.
“So if you produce energy coming from wind or solar, turn the idea into electricity in addition to then turn the idea into hydrogen, This specific can be green hydrogen,” he added.
The applications of hydrogen could be transformative. The DOE says in which a fuel cell — which turns the chemical energy in hydrogen into electricity — combined with an electric motor can be “two to three times more efficient” than an internal combustion engine which runs on gasoline.
Hydrogen can be already being used in vehicles around the globe. To give just one example, a fleet of hydrogen fuel cell buses can be currently in operation within the Scottish city of Aberdeen.
The project means in which 10 hydrogen buses are ferrying residents around the city’s streets as authorities look to reduce city center emissions in addition to boost air quality.
“They’re a very not bad fit for us because we have, like many additional cities … air quality issues,” Barney Crockett, the Lord Provost of Aberdeen, told CNBC’s “Sustainable Energy”.
