Abstract: |
Hydrogen as an energy carrier represents one of
the most promising carbon-free energy solutions. The
ongoing development of power-to-gas (PtG) technologies
that supports large-scale utilization of hydrogen is therefore
expected to support hydrogen economy with a final
breakthrough. In this paper, the economic performance of a
MW-sized hydrogen system, i.e. a composition of water
electrolysis, hydrogen storage, and fuel cell combined heat
and power plant (FCCHP), is assessed as an example of
hydrogen-based bidirectional electrical energy storage
(EES). The analysis is conducted in view of the Danish
electricity spot market that has high price volatility due to
its high share of wind power. An economic dispatch model
is developed as a mixed-integer programming (MIP)
problem to support the estimation of variable cost of such a
system taking into account a good granularity of the
technical details. Based on a projected technology
improvement by 2020, sensitivity analysis is conducted to
illustrate how much the hydrogen-based EES is sensitive to
variations of the hydrogen price and the capacity of
hydrogen storage. |
