HYFLEXPOWER seeks to prove that hydrogen can be produced and stored from renewable electricity and then added with up to 100% to the natural gas currently used with combined heat and power plants.

Exciting to see this proof of concept coming to market-- how long do you think it would take from a successful implementation here to wider adoption in other places that could use it? Are we finally maybe in the decade of hydrogen?

I am guessing the key determinant would be economic. Given the low prices of oil and natural gas I suspect some of the investments in scaling up alternative technologies will go on the back-burner.  But I hope pilots will continue.

A combined heat and power application is a good choice for demonstrating P2G2P. The big downside to P2G2P with current electrolysis and fuel cell technologies is low round trip efficiency. It's around 40%. That could conceivably be brought up a few percent -- perhaps even to 50%. But for reasons I won't go into, it won't be possible to do better without radical developments in technology.

With a CHP application, low round trip efficiency problem is not the killer it would be for straight power storage. Much of the 60% of input energy that would otherwise be wasted is no longer waste. It can be used for heat. It's pretty low grade heat -- below the boiling point of water -- but it can be efficiently upgraded. Using it on the cold side of a heat pump cycle, it can be upgraded to 150 - 200 C process steam with little additional energy input.

A nice feature of the process heat application is that it can be continuous. Waste heat is available regardless of whether hydrogen is being produced or consumed.
