Abstract
The transition toward a low-carbon energy system encourages academicians to research innovative energy solutions. Diversifying renewable energy sources ensures the effort to fulfil market demand comes into being. This study presents a comprehensive techno-economic assessment of Power-to-Gas technology to produce hydrogen using TALOS-WEC as energy converter from wave energy to electricity. Power-to-Gas is a technology that converts electrical energy into gaseous fuel and TALOS-WEC is a novel multiple degree of freedom wave energy converter developed by Lancaster University, UK. The system in the study utilises a decommissioned offshore oil platform and uses seawater as a raw material, which brings forward the advantage of abundance. The study considers separation, electrolysis, compression or liquefaction, and a transportation system. An economic analysis and economic potential study has been done for each system and then a levelized cost of energy analysis has been calculated. A process flow diagram of the plant can be seen for the purpose of visualising the system setup. The LCOE of the suggested technology is at 123.19 $/MWh and the cost breakdown shows that the decommissioned oil platform will cost the most at 32.5 M $/yr followed by hydrogen compression technology and TALOS at 1.6 M$/yr and 1.5 M$/yr respectively for the stated operating period. This study has shown optimistic results for the Power-to-gas technology, but further research and development needed for TALOS-WEC to become feasible for the system.
期刊介绍:
Fuel Processing Technology (FPT) deals with the scientific and technological aspects of converting fossil and renewable resources to clean fuels, value-added chemicals, fuel-related advanced carbon materials and by-products. In addition to the traditional non-nuclear fossil fuels, biomass and wastes, papers on the integration of renewables such as solar and wind energy and energy storage into the fuel processing processes, as well as papers on the production and conversion of non-carbon-containing fuels such as hydrogen and ammonia, are also welcome. While chemical conversion is emphasized, papers on advanced physical conversion processes are also considered for publication in FPT. Papers on the fundamental aspects of fuel structure and properties will also be considered.
