This allowed refiners to minimise the capital and operating costs of hydrogen supply to meet ever stricter environmental regulations and also increase hydrotreater yields.

It is an orange K-type subgiant star, meaning it has nearly completely exhausted its hydrogen supply in its core.

Other theorists proposed the explanation that blue stragglers were somehow more efficient in mixing their internal hydrogen supply, thus extending their youthful phase as blue stars.

The act also appropriates funds for hydrogen supply and fuel cell technologies up to year 2020, yet the amounts for each year from 2011 through 2020 are "as necessary".

The oxygen supply was terminated before the hydrogen supply, as the SSMEs reacted unfavorably to other shutdown modes.

The hydrogen supply was shut off within 10 minutes, but it took two hours to put out the blaze.

Another possibility could come in the far future, when according to computer simulations a red dwarf becomes a blue dwarf as it's exhausting its hydrogen supply.

Suddenly it didn't seem so unlikely that they could have consumed an entire gas giant's hydrogen supply.

The fusion takes place after the star has used up its hydrogen supply.

At present, 4.5 billion years into its "main sequence" phase, the Sun is quietly burning its hydrogen supply and increasing very slightly in luminosity.
