Power-to-Gas (Hydrogen) Request for Expression of Interest

Background

Power-to-gas (P2G) refers to the process of converting electrical energy to a gaseous fuel – in this case hydrogen – through the electrolysis of water.

P2G presents potential opportunities and implications related to the mandate of the IESO. P2G applications may be used to optimize and derive greater benefit from existing electricity system assets. The electricity load associated with P2G projects can be flexible and dynamic – responding to electricity prices or system conditions. P2G applications can also harness clean surplus electricity to produce hydrogen. This hydrogen can then be used as an alternative to fossil fuels for uses that include transportation, heating, power generation, and industrial or chemical processes to displace the use of GHG-emitting energy sources. Some P2G applications can also include generation, using stored hydrogen to supply electricity through fuel cells. 


Activities

Through a Request for Expression of Interest (RFEI), the IESO will seek to understand and identify different P2G technologies and their potential applications, as well as their associated technical and operational characteristics and potential benefits and challenges from an electricity system perspective. The public will be able to provide feedback on this draft RFEI.

The IESO will also perform market research on P2G, including a review of regulatory requirements.

This engagement initiative will culminate in the identification of options for pilot projects. All interested parties are invited to participate in this engagement initiative.

All comments and enquiries in the engagement initiative can be directed to engagement@ieso.ca.

December 7, 2018

The IESO has placed the Power-to-Gas (Hydrogen) Request for Expression of Interest on hold. The IESO would like to thank all stakeholders that have participated in the early development of the Power-to-Gas initiative and note that any future information regarding the status of the initiative will be communicated on this engagement webpage.

Thank you again for your input to this point.
