ASSESSING THE H2 POTENTIAL IN THE PT ENERGY SYSTEM
[2]
(a) Analysis of current and emerging H2 chains (focus on mobility and storage of variable intermittent
RES power)
(b) Review and update H2 tehnologies in TIMES
(c) Simulation, using the TIMES_PT model on the cost-effectiveness of H2 deployment in Portugal in
several scenarios, including very high share and variable CO2 mitigation targets
(d) Develop a Road map for the development of H2 technologies in the Portuguese energy system till
2050
18 months - first results April 2018

Hydrogen-report-Oct-2016.pdf
“Hydrogen has often been criticised for being an inefficient way of using
energy, but a system approach should be taken, when comparing it with
other options, that takes into account the flexibility of hydrogen and how it
can supply multiple markets. Hydrogen should therefore be evaluated on
the cost effectiveness of the overall system and its potential
environmental impacts, primarily carbon reduction“
H2 IN TIMES_PT
Older version of TIMES_PT includes approx. 90 H2 technologies (last update 2010)
› 15 options for H2 production (gaseification, electrolysis, partial oxidation, thermochemical cycles);› 15 options for H2 conversion and distribution;› 60 options for end-use consumption of H2 for power generation and heat production in buildings,
industry and for transport (bus, cars and heavy duty trucks)

SOME TOUGHTS
› communicating with the H2 world› e.g. costs units in ton H2 or m3 H2 not €/kW; lifetime in operation hours not years
› H2 feedstocks are very varied and fundamental to explain why some feedstock are in and some are not
› simplify your model – update SubRES based on scenarios to explore› less effort on fossil based generation options
› modular H2 supply for transport instead of very detailed representation of all possibledistribution options
› ignore liquid H2 possibilities for transport
› specify format of operation for some technologies considering the specificpathway: lifetime of PEM might not be 3 years depending how it is operated
