'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).

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).

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).

When talking about a chemical reaction, both words can describe the release of heat or gas. „Entwickeln“ more generally indicates that something is produced or released in the process, while „freisetzen“ emphasizes that it was previously bound or enclosed. „Entwickeln“ fits a general observation, while „freisetzen“ is more appropriate for the deliberate release of something.
