ITM’s HGas product brings together rapid response and self-pressurising PEM electrolysis into a fully integrated package. Capable of addressing MW scale applications, HGas accommodates fluctuating power profiles while generating hydrogen at pressures suitable for either direct injection into natural gas networks or via methanation processes without additional compression.
As the shift from fossil fuel to renewable power generation continues, the need for large scale and long term energy storage grows rapidly. The fact that renewable power is often intermittent and therefore difficult to apply directly to traditional storage technologies makes this challenge even more acute.
Rapid response electrolysis offers an effective route to assimilate renewable power and convert it to hydrogen which can be stored for long periods for subsequent use as a fuel for heat, mobility or power generation.
Power-to-Gas is a methodology of introducing such hydrogen to the natural gas network, essentially converting renewable electrical power to a clean gas that can be more conveniently stored using existing assets. There are two main Power-to-Gas mechanisms. The first involves metering pressurised hydrogen into the gas network directly. The second involves combining hydrogen with carbon dioxide via a methanation process to produce synthetic natural gas prior to introduction to the grid.
HGas is a product designed specifically for power to gas applications and is capable of self-pressurising up to 80 bar and responding in 1 second. The modular philosophy allows up to 1MW of electrolysis to be accommodated within one 20 foot shipping container.
