The following is based on a translation from Chinese media:

Mil.huanqiu.com reports that China has successfully developed its homegrown large (10 kW grade) liquid hydrogen low temperature refrigeration equipment, a very important device for its space program.

The device involves top advanced technology which has been withheld from China by the rest of the world.

It has taken Chinese researchers four years of hard work to make the equipment with the support of various government agencies.

For hydrogen to be stored as a liquid, it needs to be cooled to 20.28 K.

This is done using a compressor resembling a jet engine in both appearance and principle.

It is commonly used as a fuel in rocket engines.

The new technology will greatly enhance China’s space exploration capabilities.
