Per il possibile legame con la parola euphoria.

Se effettuiamo lo stesso "gioco" con la parola estasi potremmo usare
"Stasìa"

L'ultima proposta viene da qui:
http://www.nomeo.it/nomi-e/euporo.asp
"Eupora"
"Upora"
Lo so che potrebbero sembrar follia ma... a richiesta assurda del cliente = risposta assurda del traduttore...!

Scherzi a parte scriverei queste proposte al cliente chiedendogli se ce n'è qualcuna che gli piace visto che non vuole assolutamente dire né cosa sia, né il settore.

My solutions are an attempt to be creative and keep at the same time the root of the word alive.

a noun can also be created 'sprizzaenergia'

I agree with Diego 100%
The word "euphoria" is derived from the Ancient Greek terms εὐφορία: εὖ eu meaning "well" and φέρω pherō meaning "to bear".[11][12] It is semantically opposite to dysphoria.

[...]
A 1903 article in The Boston Daily Globe refers to euphoria as "pleasant excitement" and "the sense of ease and well-being".[17] In 1920 Popular Science magazine described euphoria as "a high sounding name" meaning "feeling fit": normally making life worth living, motivating drug use, and ill formed in certain mental illnesses.[18] Robert S. Woodworth's 1921 textbook Psychology: A study of mental life, describes euphoria as an organic state which is the opposite of fatigue and "means about the same as feeling good."[19]

Of course I think... everybody is asking him/herself.. ,
what about the Italian word EUFORIA?!?
It has a positive connotation.

altra possibilita'

elation (intense joy) = esultanza

Ma rimango del parere che il motto scelto coglie il neologismo.
