The shift from fossil fuels to clean energy carriers, such as renewable H2, is imminent. Consequently, a global H2 market taking shape, involving countries with limited or insufficient resources importing renewable-rich countries. This study evaluates the techno-economics of hydrogen (H2) export in globally significant scenario which Australia exports Japan. To gain insight into immediate, realisable future, base year was selected 2030, consequently small (in terms) production rate 100 t/day landed capacity. Electricity generated by photovoltaic arrays (PV) connected directly proton exchange membrane (PEM) electrolyser plant, allowing for flexible gaseous (GH2) production. enhance fidelity technoeconomic model, we incorporated rarely applied but impactful parameters, including dynamic efficiency and overload capacity PEM electrolysers. GH2 produced assumed be converted condensed forms suitable sea: liquid (LH2), chemical carriers ammonia (LNH3), methanol (MeOH), methylcyclohexane (MCH). These were reconverted at destination. LNH3 MCH emerged promising export, yielding lowest levelised cost (LCOH). LH2 yielded highest LCOH unless boiloff gas could managed effectively cheaply. A sensitivity analysis showed that lower weighted average capital (WACC) scale-up can significantly reduce LCOH. Increasing 1000 very lowered LCOH, providing strong incentive scale up optimise entire supply chain fast possible.

Given the urgent need to accelerate all renewable energy capacities for hydrogen production, this study undertakes a techno-economic analysis of dynamic production using offshore wind under "slow progress" and "fast scenarios. To ensure reliable power generation profile avoid overestimating output power, takes into account significant impacts air density plant-level losses, including wake effect turbine performance losses. The economic modelling incorporates costs associated with turbines, foundations, submarine connections, substations, installations. For system electrolysis, power-dependent efficiency representing PEM technology is employed. reflect influences realistic project on estimation levelised cost (LCOH), economies scale learning rate models are incorporated. Australian locations selected as case implementing model because enormous available resource. findings indicate that variable nature input has meaningful impact yearly average consumption electrolysis system. Comparing scenarios, it becomes evident rapid scaling up required achieve cost-competitive LCOH in coming decades. Should interest rates thus capital return levels closer pre-pandemic levels, level below AUD3/kg (USD2/kg) can be achieved scenario two by around 2040.
