Technology Development Board (TDB) and Type-IV Composite CNG Cylinders

The Technology Development Board (TDB) has recently entered into an agreement with a private sector company to establish an advanced manufacturing facility for the production and commercialisation of indigenously developed Type-IV Composite CNG Cylinders. This initiative supports India’s push towards cleaner energy technologies and domestic manufacturing in the automotive and energy storage sectors.

“Indigenous technology development is key to achieving energy security and sustainable mobility.”
