TÜV SÜD has developed a guideline for defining the "H2 readiness" of power plants and offers independent certification for original equipment manufacturers (OEM) and plant constructors (EPC). The certification increases investment security for energy suppliers. Siemens Energy is the first company worldwide to receive certification for its "H2-Ready" power plant concept. The new TÜV SÜD guide was developed in cooperation with Siemens Energy.
