to release
To release something that was bound or enclosed. Often refers to energy, gases, or chemical substances in physical or chemical processes.
Bei der Verbrennung von Holz wird Wärmeenergie freigesetzt.
When wood burns, thermal energy is released.
'Freisetzen' (to release / to lay off) is a separable verb. The prefix 'frei-' separates from the base verb 'setzen' in main clauses and goes to the end of the sentence. In subordinate clauses and in the infinitive, the verb stays together.
Die Reaktion setzt viel Energie frei.
The reaction releases a lot of energy.
The meaning of 'freisetzen' (to release / to lay off) depends heavily on the object. If it refers to 'Energie' (energy) or 'Stoffe' (substances), the scientific meaning is intended. With 'Mitarbeitern' (employees), it is about layoffs. With 'Kräften' (forces) or 'Potenzial' (potential), the abstract meaning is intended.
Das Kraftwerk setzt große Mengen CO₂ frei.
The power plant releases large amounts of CO₂.
In a scientific context, 'freisetzen' (to release) is often combined with nouns such as 'Energie' (energy), 'Wärme' (heat), 'Gase' (gases), 'Stoffe' (substances), or 'Schadstoffe' (pollutants).
Bei dem chemischen Prozess werden giftige Gase freigesetzt.
Toxic gases are released during the chemical process.
In the meaning 'Mitarbeiter entlassen' (to lay off employees), 'freisetzen' (to lay off) is a formal and often euphemistic expression. It sounds less direct and harsh than 'entlassen' (to dismiss/lay off) or 'feuern' (to fire).
Im Rahmen der Umstrukturierung werden 100 Angestellte freigesetzt.
As part of the restructuring, 100 employees will be laid off.
In the abstract meaning, 'freisetzen' (to unleash/release) is often connected with positive, invisible forces. Typical combinations are 'Potenzial freisetzen' (to unleash potential), 'Kräfte freisetzen' (to release forces), or 'kreative Energien freisetzen' (to unleash creative energies).

to develop
'entwickeln' and 'freisetzen' can both occur in chemical or physical processes, for example with gas, smoke, heat, or energy. Here, 'entwickeln' means that something is produced or generated in a process. 'freisetzen' means that something was already present or bound and now becomes free. Learners may confuse the words because the result can look similar: in the end, for example, there is gas. The difference lies in the perspective: 'entwickeln' emphasizes production or coming into being, while 'freisetzen' emphasizes being released.

When wood burns, smoke is released.
Beim Erhitzen entwickelt die Flüssigkeit einen starken Geruch.
