Cryogenic Hydrogen Technology

By Prof. Indranil Ghosh | IIT Kharagpur

Learners enrolled: 680 | Exam registration: 21

ABOUT THE COURSE:

By and large, the implementation of a hydrogen fuel-based economy can not be done without the help of cryogenics. The footprints of cryogenics are seen in the large-scale production of this fuel, bulk transportation of it from one point to another, and some of the applications based on liquid hydrogen. One must be aware of the unique temperature-dependent properties of hydrogen for its design and simulation at the system and component levels. This course provides a consolidated overview of cryogenic hydrogen production, storage, transportation, and its end use. The safety aspects of handling cryo-hydrogen and the necessary precautions will also be discussed.

PREREQUISITES: Basic thermodynamics

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.

The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).

Date and Time of Exams: May 4, 2025 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.

Registration url: Announcements will be made when the registration form is open for registrations.

The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.

Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 6 assignments out of the total 8 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

Please note that assignments encompass all types (including quizzes, programming tasks, and essay submissions) available in the specific week.

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Kharagpur .It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.

Once again, thanks for your interest in our online courses and certification. Happy learning.
