Summary: This paper discusses the feasibility of using a photovoltaic energy system to produce hydrogen from solar energy in the four main cities of Iraq. A simulation of an off-grid photovoltaic system with an alkaline electrolyser, hydrogen compressor, and hydrogen tank was conducted for one year. The results show that the annual hydrogen production ranges from 1713.92 kg to 1891.12 kg, with an evaluated cost of $3.79/kg. The study suggests that the optimal sites for solar hydrogen production systems are in the midwest of Iraq and other cities with similar climates.

Summary: This paper proposes a new integrated process for carbon dioxide capture, hydrogen production, power generation, heat generation, and methanol production using flue gas from a power plant. The process has low CO2 emission, low production cost, and high thermodynamic efficiency. Simulation results show a methanol production of 606,228 tons/year and a CO2 emission intensity of 0.61 kgMeOH. The overall energy efficiency of the process is 56.74% and the total production cost of methanol is 0.52 $/kgMeOH, which is lower compared to similar technologies based on renewable energy by 64.86%.

Summary: Current ammonia production based on SMR coupled to the HB process accounts for 1.2% of global CO2 emissions. The ammonia industry is considering electrification as a way to reduce emissions by replacing SMR-based production with electrolytic H2 production. This paper critically assesses the implications of this shift and finds that electrification can significantly reduce emissions, but only with 100% renewable electricity and improvements in energy efficiency.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
