Green energy

Green Hydrogen (gH2)

Green Hydro­gen (gH2) enables indef­i­nite ener­gy stor­age and mul­ti­ple uses. Indus­try and mobil­i­ty need gH2 to reduce and even­tu­al­ly elim­i­nate their car­bon foot­print. The high con­sump­tion of elec­tri­cal ener­gy still makes gH2 dif­fi­cult to com­pete with Grey Hydro­gen which is pro­duced indus­tri­al­ly at low cost by steam reform­ing of nat­ur­al gas (at the cost of using a fos­sil resource and releas­ing 10 times more CO2 than H2)…

Con­tin­u­ous tech­no­log­i­cal progress can make gH2 com­pet­i­tive before the year 2030. Its large-scale use depends, among oth­er things, on restric­tive mea­sures for the use of fos­sil fuels (car­bon tax, tax­a­tion of con­ven­tion­al fuels, etc.).

The pro­duc­tion of off­shore gH2 using MRE, pro­posed by GHy­GA in its 2W2H2 project®, can achieve com­pet­i­tive­ness com­pared to oth­er onshore process­es, as ear­ly as the begin­ning of the 2030s (after val­i­da­tion of the pro­to­type fac­to­ry plat­form, by launch­ing upcy­cled plat­forms equipped in series after 2025).

Green Ammonia (gNH3)

In addi­tion to its wide­ly used qual­i­ties in the chem­i­cal indus­try, espe­cial­ly for fer­tilis­er pro­duc­tion, gNH3 is an excel­lent fuel with no CO2 emis­sions. The use of gNH3 in ther­mal engines and gas tur­bines is immi­nent and may come into stan­dard use as ear­ly as the 2030s. The man­age­ment of its tox­i­c­i­ty is well con­trolled indus­tri­al­ly and does not present a sig­nif­i­cant bar­ri­er to its deployment.

Based on the 2W2NH3® con­cept devel­oped by GHy­GA, it is pos­si­ble to pro­duce gNH3 from 2030 on at com­pet­i­tive cost.

Green Hydro­gen rep­re­sents 90% of the pro­duc­tion cost of Green Ammo­nia.
The pro­duc­tion of gNH3 there­fore depends very much on the effi­cien­cy of the elec­trol­y­sers used.

Green Ammo­nia can become a major means to decar­bonise the ship­build­ing indus­try in the medi­um and long term. GHy­GA’s 2W2NH3 project® address­es the future needs of ship­ping and port activities.

More­over, Ammo­nia is easy to store, espe­cial­ly for the long term:
