When the electrical input comes from a renewable source, the hydrogen has no carbon footprint. This is the only practical way to generate a zero carbon fuel. ITM is developing a range of self contained electrolyser systems which produce hydrogen at convenient pressure. Hydrogen production rates fall into three ranges:
- Small: In the region of 1 litre of H2 per minute (approximately 1kg H2 per week). This is appropriate for laboratory scale analytical applications, the education market and fuel cell developers and for trickle charging hydrogen stores
- Medium: Approximately 1kg H2 per day. Units in this range may be used on their own or in tandem for home, transport and small industrial applications
- Large: As required for transport refueling and other industrial decarbonisation applications
ITM electrolysers deliver hydrogen at 15 bar which is consistent with existing propane storage technology, metal hydride storage systems and hydrogen compressors. ITM has experience of generating hydrogen directly at 75 bar, which offers a route for bypassing the need for external compression and reduces the complexity of downstream high pressure plant.
ITM’s electrolysers are modular, which provides flexibility and allows for easy expansion.
