Elon Musk has a historical past of expressing sturdy reviews about hydrogen and hydrogen gas cells. A couple of years in the past, when the topic got here up right through a dialogue with newshounds on the Car Information International Congress, the electrical automobile mogul described hydrogen gas cells as “extraordinarily foolish.”

Tesla CEO Elon Musk has reiterated his skepticism about hydrogen’s function within the deliberate shift to a extra sustainable long term, describing it as “essentially the most dumb factor I might be able to consider for calories garage.”
Throughout an interview on the Monetary Instances Long term of the Automotive summit on Tuesday, Musk was once requested if he concept hydrogen had a job to play in accelerating the transition clear of fossil fuels.
“No,” he spoke back. “I in reality cannot emphasize this sufficient — the choice of instances I have been requested about hydrogen, it could be … it is neatly over 100 instances, possibly 200 instances,” he mentioned. “You have to needless to say if you wish to have a method of calories garage, hydrogen is a nasty selection.”
Increasing on his argument, Musk went directly to state that “gigantic tanks” can be required to carry hydrogen in liquid shape. If it had been to be saved in gaseous shape, “even larger” tanks can be wanted, he mentioned.
Described via the Global Power Company as a “flexible calories service,” hydrogen has a various vary of packages and will also be deployed in sectors corresponding to business and shipping.
In 2019, the IEA mentioned hydrogen was once “one of the crucial main choices for storing calories from renewables and appears promising to be a lowest-cost choice for storing electrical energy over days, weeks and even months.”
The Paris-based group added that each hydrogen and hydrogen-based fuels had been ready to “shipping calories from renewables over lengthy distances — from areas with plentiful sun and wind assets, corresponding to Australia or Latin The us, to energy-hungry towns hundreds of kilometres away.”

Musk has a historical past of expressing sturdy reviews about hydrogen and hydrogen gas cells.
A couple of years in the past, when the topic got here up right through a dialogue with newshounds on the Car Information International Congress, the electrical automobile mogul described hydrogen gas cells as “extraordinarily foolish.”
In June 2020 he tweeted “gas cells = idiot sells,” including in July of that 12 months: “Hydrogen idiot sells make no sense.” Judging via his feedback this week, he stays unconvinced about hydrogen.
“It does no longer naturally happen on Earth, so that you both have to separate water with electrolysis or crack hydrocarbons,” he instructed the Monetary Instances.
“If you find yourself cracking hydrocarbons, you in reality have not solved the fossil gas downside, and the potency of electrolysis is deficient.”
As of late, nearly all of hydrogen manufacturing is in line with fossil fuels. Any other way of manufacturing contains the use of electrolysis, with an electrical present splitting water into oxygen and hydrogen.
If the electrical energy used on this procedure comes from a renewable supply corresponding to wind or sun then some name it inexperienced or renewable hydrogen.
Hydrogen tasks the use of electrolysis have attracted pastime from primary firms and trade leaders in recent times, however it could seem Musk isn’t a fan.
“The potency of electrolysis is … deficient,” he instructed the Monetary Instances. “So that you in reality are spending a large number of calories to … break up hydrogen and oxygen. Then you need to separate the hydrogen and oxygen and pressurize it — this additionally takes a large number of calories.”
“And if you need to liquefy … hydrogen, oh my God,” he persisted. “The volume of calories required to … make hydrogen and switch it into liquid shape is staggering. It’s the maximum dumb factor that I might be able to consider for calories garage.”
Other viewpoints
Musk could also be dismissive about hydrogen’s function within the calories transition, however different influential voices are a little bit extra positive. Those come with Anna Shpitsberg, who’s deputy assistant secretary for calories transformation on the U.S. Division of State.
Throughout a up to date panel dialogue moderated via CNBC’s Hadley Gamble, Shpitsberg referred to as hydrogen “a game-changing generation that speaks to numerous different assets … as a result of it may well underpin nuclear, it may well underpin gasoline, it may well underpin renewables, it may well blank a significant portion of it and so can CCUS [carbon capture utilization and storage].”
Somewhere else, February noticed Michele DellaVigna, Goldman Sachs’ commodity fairness trade unit chief for the EMEA area, spotlight the vital function he felt it could have going ahead.
“If we wish to pass to net-zero we will’t do it simply thru renewable energy,” he mentioned.
“We want one thing that takes nowadays’s function of herbal gasoline, particularly to control seasonality and intermittency, and that’s hydrogen,” DellaVigna argued, happening to explain hydrogen as “the most important molecule.”
The important thing, he mentioned, was once to “produce it with out CO2 emissions. And that’s the reason why we discuss inexperienced, we discuss blue hydrogen.”
Blue hydrogen refers to hydrogen produced the use of herbal gasoline — a fossil gas — with the CO2 emissions generated right through the method captured and saved. There was a charged debate across the function blue hydrogen can play within the decarbonization of society.
“Whether or not we do it with electrolysis or we do it with carbon seize, we want to generate hydrogen in a blank method,” DellaVigna mentioned. “And as soon as now we have it, I feel now we have an answer that might transform, sooner or later, a minimum of 15% of the worldwide calories markets this means that it’s going to be … over 1000000000000 greenback marketplace in line with annum.”
