VIII.a H2 Production for Transport Costs

Sources & Method

Markal2006 has H2 in some detail[1] and there are some supporting papers[2][3] on the underlying assumptions.

Markal vectors (FIXOM/INVCOST/VAROM; VAROM is in M£/PJ, INVCOST and FIXOM is M£/PJ/annum, using year 2000 GBP):

  • current large SMR - SG08 - 0 / 4.1 / 1.4 (30 year life)
  • current large SMR with CO2 capture - SG09 - 0 / 7.6 / 1.4 (30 year life)
  • future large SMR - SG10 - 0 / 5.8 / 0.7 (30 year life) NB. This is higher than current SMR, and appears to be a data error, which is currently being addressed in UK MARKAL through the UKSHEC project
  • future large SMR with CO2 capture - SG11 - 0 / 6.2 / 0.705 (30 year life)
  • liquefaction of hydrogen to LH2 - SH01 - 0 / 18.38 / 0.78
  • hydrogen pipeline network - SH03 - 0 / 11.97 / 0 (Based on 200km pipeline)
  • current small SMR - SH04 - 0 / 46.07 / 1.37 (20 year life)
  • future small SMR - SH05 - 0 / 32.03 / 0.705 (25 year life)
  • hydrogen from electrolysis ? small, current - SH07 - 0 / 70.98 / 0 (15 year life)
  • hydrogen from electrolysis ? small, 2020 - SH08 - 0 / 15.87 / 0 (20 year life)
  • hydrogen from electrolysis ? large, current - SH09 - 0 / 42.08 / 0 (15 year life)
  • hydrogen from electrolysis ? large, 2020 SH10 - 0 / 4.893 / 0 (25 year life)

2050 Pathways has: SMR - Central, SMR - Distributed, Electrolysis. Map the SMR - Central to large SMR and the SMR distributed to small SMR. Map electrolysis to all sizes of electrolysis in Markal. Ignore the with CCS options. Standardise everything on a 25 year life, and use that to mean that one fifth of opening capital needs replacing in a five year block. Assume that end result is always liquid H2 [4]. Assume that the large scale requires pipeline costs and that the electrolysis requires pipeline costs half of the time.

Questions to stakeholders

  • Can electrolysis really have no operating costs?
  • Do the piping costs seem sensible?

  4. This is a very odd assumption - almost all major car manufacturers are producing prototypes with compressed gaseous hydrogen, typically at either 350 or 700 bar
