Hydrogen system - No feasible solution

Hi

I’ve been using Homer for some time already and I’m confident simulating various PV-battery-grid systems. I’m now working on a hydrogen system and struggle with “infeasible solutions”. I started simple with four components: grid, electrolyzer, hydrogen tank, and hydrogen load. But the system won’t find any solutions. It feels like I’ve tried it all, more components, other controllers, different start-values, etc. Any ideas on what to do next?

Thanks in advance

Hello Jonathan,

 

The following knowledgebase article would help understand Hydrogen model in HOMER Pro:  http://usersupport.homerenergy.com/customer/en/portal/articles/2189019-hydrogen-energy-storage-in-homer

 

Best,

Hi Dhiwaakar, thanks for the reply.

According to the article, this is what I'm trying to do:

"HOMER can also model hydrogen production systems, meaning systems whose purpose is to generate hydrogen rather than (or in addition to) electricity."

And I've added a PV component that produces excess electricity. The problem is still that there are no feasible solutions until I set the "Maximum unmet hydrogen load" to 100%. Only then will it run, but without producing hydrogen.

Any more ideas?
