Total Energy #211

Closed koay9f closed 1 month ago

Ability to have Total Energy for systems with multiple energy types (TH & Hybrid PH) Impacts: Industrial systems, pre-assessment, assessment, Energy opportunities

RLiNREL commented 1 month ago

@koay9f could you provide some guidance on the energy conversion from mass (kg, lb), volume liquid (kgal), volume gas (kscf) to common energy unit (kwh/MMBtu/J)? Thanks!

Also, should we consider using different notations to distinguish these units from standard mass and volume measurements? e.g. kg-energy, kgal-energy?

RLiNREL commented 1 month ago

The total energy is implemented in the pre-assessment page PR 251

The remaining and related issues are split into other issues:

If the "collection" or price unit is in mass or volume, then you need to ask users for the "Higher Heating Value". For Natural Gas we can provide this 0.001029 MMBTU/scf and do conversions for any other gas volume or energy unit. We can also probably have a list of common materials in a dropdown for other fuels with HHV. VERIFI has all this. but for now, a field with HHV should be enough.
