The Binden administration believes that pure hydrogen will be part of a set of tools needed to shift the United States to zero emissions by 2050, not to mention a 50% reduction in those emissions by the end of this decade. But a peer-to-peer survey on Thursday argues that oil evidence should be reconsidered.
Some energy-industry and fresh air analysts have raised concerns, published in the Journal of Energy Science and Engineering by researchers at Cornell and Stanford Universities, distorted short-term findings into long-term perspectives, misrepresented others, and risked unintended development of technology. He is exposed.
Hydrogen is already used in some applications, but it has historically been the most expensive to replace fossil fuels. The International Energy Agency, in an anti-oil report that surprised many earlier this year, has highlighted the role of hydrogen in the new energy world.
Most of the hydrogen used today comes from natural gas NG00;
In the process of producing carbon dioxide as well as faster, but more powerful methane. The study focuses on these emissions.
Researchers, Robert Hawart, Cornell Biochemistry and Ecology Scientist at Cornell, and Mark Jacobson, Stanford Professor of Civil and Environmental Engineering and Director of Atmospheric Energy, have examined greenhouse gas emissions for the “blue” hydrogen, accounting life cycle. For both carbon dioxide emissions and non-combustible methane, the United Nations has raised concerns about methane elimination.
When the natural gas industry looks to further hydrogen production, it pushes for emissions and, according to the industry, leaves “blue” hydrogen. That “green” is short, but it still reduces pollution. “Green” hydrogen needs to be used as a zero-emission renewable energy, wind or sun, and electrolysis water to separate hydrogen atoms from oxygen. Renewable energy is not yet common – although it is becoming more and more expensive – to replace natural gas in the process.
In the paper’s “blue” hydrogen supply chain, the process actually generates more than natural gas for natural use.
The researchers identified carbon dioxide emissions and methane emissions during natural gas production. It is estimated that 3.5% of the earth’s gas emissions go into the atmosphere, and that percentage of natural gas is extracted from methane, according to research. And they added to the natural gas needed to turn on carbon-holding technology.
Overall, blue hydrogen-greenhouse gas emissions account for more than 20% of natural gas or coal burning, and more than 60% for diesel oil.
“Our analysis shows that carbon dioxide can be stored indefinitely, with optimism and uncertainty,” he said. Although it is true, the use of blue hydrogen seems to be difficult to determine due to climatic factors.
In Washington, an energy-focused policy development team, Frank Maisano, a senior industrial lobbyist, found the researchers’ approach difficult.
“Both are well-known for their research on climate-related topics, but any short-term life cycle analysis seems to be proven to overestimate the long-term effects and minimize the potential benefits of hydrogen,” Maisano said. “In previous analyzes, I found it ridiculous to look at both the whole climate and the future of the project, but when it comes to hydrogen, it probably seems to shorten its long-term potential and real technological advancement. It happens. ”
Maisano said the report erroneously compared hydrogen to a source of heating and traditional alternatives.
“Basically, if you want to heat water, blue hydrogen is not as environmentally friendly as other fuels. We are not using it for heat, we are putting it into fuel cells and using it for its electrochemical properties, ”he said.
The Air Force was also a threat.
“The paper framework seems to compete with ‘blue hydrogen’ and ‘green hydrogen’ alternatives. However, by the middle of the century, we may be looking for both to achieve decarbonation, ”said Mike Fouer, director of CATF, which provides data and policy initiatives behind nuclear, bio energy and other sources. .
“Blue sources are currently smaller than green and may provide an important source of low-carbon hydrogen as the price of green decreases,” he said. Considering the urgency of decarbonation, the paper shows a false choice.
CATF also confirms that the estimated methane-loss in paper is high. He said the current best-of-breed analysis estimates that the U.S. flow rate is about 2.3%.
“Essentially, this flow must be very low and must be done,” Fouler said.
Hydrogen development was highlighted this week in the Senate’s fragmented and bilateral infrastructure budget. The bill now goes to the House of Representatives. Meanwhile, some climate-related programs have been compromised by Democrats.
David Hart, a political policy expert at George Mason University, told Science Insider magazine that the inclusion of hydrogen in the Senate infrastructure bill is a $ 8 billion purchase from Washington for regional hydrogen centers. EV Manufacturer Nikola Corporation NKLA,
On Thursday, he said he had found research to refuel at hydrogen stations. And Wall Street, with at least two hydrogen-related exchanges, Global X Hydrogen ETF HYDR, preceded the piece of action.

Hydrogen pressure in the energy industry and in some local groups is a big factor in Europe and elsewhere, so the study has implications for these more mature markets. Royal Dutch lDS RDS.B,
For example, it has a hydrogen production plant in Wesselsing, Germany, where subsidies are widely available in the United States.
The U.S. natural gas industry has pushed for more pipelines, saying the system will eventually transport pure gas and hydrogen.

According to a McKinsey estimate, the Hydrogen economy will generate $ 140 billion a year and 700,000 jobs by 2030, along with other large oil and gas companies. Hydrogen could meet 14% of US energy demand by 2050, he said.
