Thin films

At the heart of CAMPFIRE ener­gy tech­nolo­gies are elec­tro­ce­ram­ic mem­branes with per­ovskite struc­tures, which are thin­ner than a mil­lionth of a metre and can be man­u­fac­tured in a process that is cost-effec­tive and resource effi­cient. Per­ovskites pro­vide sig­nif­i­cant ben­e­fits thanks to their high-tem­per­a­ture elec­trolyte mate­ri­als, mechan­i­cal load-bear­ing capac­i­ty, phys­i­cal-chem­i­cal prop­er­ties and tem­per­a­ture resis­tance and are able to con­duct oxy­gen ions, pro­tons and electrons.

Green ammonia

In the future, con­ven­tion­al inter­na­tion­al meth­ods for ammo­nia syn­the­sis, which are based on fos­sil fuels, will be replaced and decen­tralised. This will make direct ammo­nia pro­duc­tion from renew­able sources eco­nom­i­cal­ly fea­si­ble on an indus­tri­al scale. The CAMPFIRE project is devel­op­ing inno­v­a­tive ener­gy tech­nolo­gies with high process effi­cien­cy and low costs for ammo­nia syn­the­sis from renew­able ener­gy sources. Mixed-con­duct­ing oxy­gen sep­a­ra­tion mem­branes can be used to pro­vide nitro­gen from ambi­ent air, which is avail­able every­where. Green ammo­nia can be pro­duced effi­cient­ly in a decen­tralised man­ner using a micro-Haber-Bosch process in the pres­ence of high-vol­ume flows from wind or solar pow­er. Pro­ton-con­duct­ing mem­branes enable an effi­cient sol­id-state ammo­nia syn­the­sis process (SSAS) for the for­ma­tion of ammo­nia from nitro­gen and water vapour. In the future, SSAS will be a cost-effec­tive and ener­gy-effi­cient alter­na­tive to the Haber-Bosch process.

Marine propulsion

Green ammo­nia makes it pos­si­ble to decar­bonise mar­itime ship­ping. At nor­mal tem­per­a­tures, it can be liqui­fied at a pres­sure as low as 8 bar (-33°C at nor­mal pres­sure), which allows for easy stor­age and trans­port. Ammo­nia con­tains approx­i­mate­ly 17% of hydro­gen and has an ener­gy con­tent com­pa­ra­ble to that of methanol. Our approach is two-fold: to use ammo­nia direct­ly or par­tial­ly con­vert­ed to hydro­gen in com­bus­tion engines and gas tur­bines, and to direct­ly con­vert ammo­nia or hydro­gen into elec­tric­i­ty in a fuel cell for marine ship­ping. When con­ven­tion­al NOX emis­sion con­trol appli­ances such as SCR are used, the end prod­ucts are only water and hydro­gen, which can be returned to the air safely.
