nasa is designing the first ever all-electric airliner which will produce no greenhouse gas emissions - electrical energy storage systems
NASA-
The research funded is investigating the development of the whole-
Electric aircraft that do not produce greenhouse gas emissions.
Led by scientists at the University of Illinois, the project is exploring the potential of liquid hydrogen fuel cells as an environmental power source.
By using cooled condensate hydrogen instead of hydrogen, clean power can be generated without the need for heavy-duty pressurized tanks.
The shift will bring viable hydrogen power to large aircraft for the first time and revolutionize the commercial aviation industry.

Funded projects are led by aerospace engineer Philip Ansel, electrical engineer Kiluba Harlan and colleagues from the University of Illinois at Urbana
Champagne from America.
The project was named "Low temperature High-Tech Center ".
In short, efficient electrical technology for aircraft or CHEETA.
NASA will provide a total of $6 million (£4. 6 million)
Finish the project in three years.
Professor Ansel said that in essence, the focus of the project is to develop a fully electric aircraft platform that uses low-temperature liquid hydrogen as an energy storage method.
Hydrogen chemical energy is converted into electric energy through a series of fuel cells, which promotes
An efficient power propulsion system, he added.
Hydrogen batteries were previously used to power cars and trains, but heavy-duty tanks that needed to contain enough pressurized hydrogen to power the aircraft prohibited their practical use on large aircraft.
But by using liquid hydrogen, CHEETA's researchers plan to bypass this limit.
At the same time, the low temperature required to run the liquid hydrogen fuel power supply can be allowed to be used at the same time as the high temperature
High efficiency technology and high power transmission
Power motor system.
The working principle of these applications is similar to the working principle in the hospital MRI scanner, which uses the magnet of the liquid helium cooling machine until the conductivity required to produce a high-intensity magnetic field is obtained.
For now, however, connect this power supply to the electricity-
The application of such driving technology on large aircraft has not been effectively realized.
The CHEETA project aims to bridge this gap and pave the way for the creation of fully electric passenger planes in the future.
"In recent years
Professor Haran said that low-temperature machines and drives bring the power advance of commercial feeder aircraft closer to reality.
But practical low-temperature systems are still the "holy grail" of large aircraft because of their unmatched power density and efficiency, he added.
The partnership established for this project has enabled us to address the significant technical barriers that exist on this path well.
Over the past few decades, improvements in aircraft structure and engine design have improved aircraft efficiency.
However, the continued reliance of the aviation industry on fossil fuels means that air travel remains an important contributor to global greenhouse gas emissions.
In the United States alone, the dependence on air travel is expected to increase by 90 in the next 20 years.
Moreover, reliance on fossil fuels means that the cost of aircraft operations is inherently unstable.
