i) For all parameters involving Nm3, the temperature and pressure are at 0°C and 1 ATM
ii) Measured NHV needs to be corrected to account for the higher NHV contribution from H2.
iii) Use 48.47 MJ/Nm3 (1212 BTU/SCF) for H2 NHV based on previous empirical studies
iv) US EPA Regulatory requirement for NHVdil is 22 BTU/ft2 @ 68F and 1 ATM - (40 CFR 63.670(f)) which is equivalent to 0.268 MJ/m2@ 0C and 1 ATM
