الاندماج هو ما يحدث داخل النجوم، حيث تنضغط ذرات الهيدروجين معاً حتى تتَّحد وتشكل الهيليوم، مما يؤدي إلى إطلاق كميات هائلة من الطاقة. وتأمل بعض المشاريع الكبيرة -مثل مشروع إيتر ITER في فرنسا- بأن تتمكن يوماً ما من محاكاة هذه الظاهرة على نطاق واسع على الأرض. إنها عملية شديدة التعقيد لأنها تتطلب مقادير هائلة من الضغط والحرارة، وعلى سبيل المثال: يستخدم مشروع إيتر غمامة من الهيدروجين بحرارة تبلغ حوالي 150,000,000 درجة مئوية، أي ما يساوي عشرة أضعاف حرارة جوف الشمس، وتتمحور فكرة الاندماج البارد حول الحصول على نفس النتيجة، ولكن بحرارة الغرفة.
