ConspectusProduction of hydrogen from nonfossil sources is essential toward the generation sustainable energy. Hydrogen upon hydrolysis stable hydrogen-rich materials has long been proposed as a possibility disposal on site, because transport explosive gas dangerous. Hydrolysis some boron derivatives could rapidly produce large amounts hydrogen, but this requires presence very active catalysts. Indeed, late transition-metal nanocatalysts have recently developed for few precursors.Our...

Green ammonia has received increasing interest for its potential as an energy carrier in the international trade of renewable power. This paper considers factors that contribute to producing cost-competitive green from exporter’s perspective. These include resource quality across sites, operating modes off-grid plants, and seasonal complementarity with buyers. The study applies a mixed-integer programming model uses Australia case because excellent solar wind resources, synergy between...

Green steel, produced using renewable energy and hydrogen, presents a promising avenue to decarbonize steel manufacturing expand the hydrogen industry. Australia, endowed with abundant resources iron ore deposits, is ideally placed support this global effort. This paper's two-step analytical approach offers first comprehensive assessment of Australia's potential develop green as value-added export commodity. The Economic Fairways modelling reveals strong alignment between prospective hubs...

Assessments of hydrogen project viability typically focus on evaluating specific sites for development, or providing generic cost-estimates that are independent location. In reality, the success projects will be intimately linked to availability local energy resources, access key infrastructure and water supplies, distance export ports markets. this paper, we present an economic model incorporates assessments these regional factors identify areas high potential production – so-called...

Offshore wind farms are a current area of interest in Australia due to their ability support its transition renewable energy. Climate reanalysis datasets that provide simulated speed data frequently used evaluate the potential proposed offshore farm locations. However, there has been lack comparative studies accuracy predictions from different for Australian waters. This paper assesses distribution and compares turbine power output three international datasets: BARRA, ERA5, MERRA-2. Pressure...

Australia has ambitions to become a major global hydrogen producer by 2030. The establishment of Australia’s and the world’s economy, however, will depend upon availability affordable reliable storage. Geological storage is practical solution for large scale requirements ensuring supply can always meet demand, excess renewable electricity be stored later use, improving network reliability. Hosting thick, underground halite (salt) deposits an abundance onshore depleted gas fields, well placed...

Atmospheric reanalyses are a popular source of wind speed data for energy modelling but known to exhibit biases. Such biases can have significant impact on the validity techno-economic assessments that include simulated power. This study assesses Australian BARRA-R2 (Bureau Meteorology Regional Reanalysis Australia, version 2) atmospheric reanalysis, and compares it with MERRA-2 (Modern-Era Retrospective analysis Research Applications, V2) ERA5 (European Centre Medium-Range Weather Forecasts...

Driven by the global decarbonization effort, rapid integration of renewable energy into conventional electricity grid presents new challenges and opportunities for battery storage system (BESS) participating in market. Energy arbitrage can be a significant source revenue BESS due to increasing price volatility spot market caused mismatch between generation demand. In addition, Frequency Control Ancillary Services (FCAS) markets established stabilize offer higher returns their capability...

Wind energy has been increasingly adopted to mitigate climate change. However, the variability of wind causes curtailment, resulting in considerable economic losses for farm owners. curtailment can be reduced using battery storage systems (BESS) as onsite backup sources. Yet, this auxiliary role may significantly weaken potential BESS trading. Ideal scheduling should balance reduction and market bidding, but practical implementation is challenging due coordination complexity stochastic...

This article studies the synergy of solar-battery energy storage system (BESS) and develops a viable strategy for BESS to unlock its economic potential by serving as backup reduce solar curtailments while also participating in electricity market. We model real-time bidding two Markov decision processes farm BESS, respectively. develop novel deep reinforcement learning (DRL) algorithm solve problem leveraging attention mechanism (AC) multigrained feature convolution process DRL input better...

The battery energy storage system (BESS) has immense potential for enhancing grid reliability and security through its participation in the electricity market. BESS often seeks various revenue streams by taking part multiple markets to unlock full potential, but effective algorithms joint-market under price uncertainties are insufficiently explored existing research. To bridge this gap, we develop a novel joint bidding strategy that utilizes deep reinforcement learning (DRL) bid spot...

Wind energy has been rapidly gaining popularity as a means for combating climate change. However, the variable nature of wind generation can undermine system reliability and lead to curtailment, causing substantial economic losses power producers. Battery storage systems (BESS) that serve onsite backup sources are among solutions mitigate curtailment. such an auxiliary role BESS might severely weaken its viability. This paper addresses issue by proposing joint curtailment reduction arbitrage...

Atmospheric reanalyses are a popular source of wind speed for energy modelling but known to exhibit biases. This study assesses the Australian BARRA-R2 atmospheric reanalysis, and compares it with MERRA-2 ERA5. Simulated power is compared observed from 54 farms across Australia using site-specific turbine specifications. We find that all replicate patterns associated passage weather systems. However, at shorter time intervals, correlation variable. Assessed by bias, correlation, error, gave...
