South Korea has released major news that it has developed an enhanced material to contain hydrogen fuel that could significantly reduce the size of containers, while also holding more fuel.
The new material could help speed up the development of hydrogen-fuel cars while improving the efficiency and overall competitiveness of such vehicles, as it can help reduce the size of fuel tanks, according to the Ministry of Education, Science and Technology.
Existing hydrogen containers employ microporous materials, which have small pores that hold hydrogen and measure 0.321 nanometer in diameter.
According to the ministry, the local experiment team has successfully expanded the size of pores in the material to 0.8 nanometers by injecting pyridine molecules that work as pillars between layers of the porous material.
Consequently, the density of hydrogen in the new pillared material rose to 61.7 grams per liter(g/L) from only 40 g/L in conventional materials.
This almost meets the performance standard for hydrogen fuel tanks in cars suggested by the U.S. Department of Energy, which weighs 70g/L.
