Summary: This study aims to elucidate the process design and techno-economic feasibility of hydrogen production from palm oil mill effluent (POME) using steam methane reforming in the context of Malaysia. The simulation results showed that a feedstock of 20,000 kg per hour of POME could generate 963.31 tonnes of hydrogen annually. The estimated capital expenses and operating expenses for the hydrogen production facility were RM 142.49 million and RM 58.67 million/year, respectively. The study provides valuable information for potential alternative hydrogen production methods and can help accelerate the commercialization of hydrogen production technologies.

Summary: This study proposes a carbon-neutral hydrogen production process from natural gas using electrified steam methane reforming (e-SMR) with renewable electricity. Compared to conventional fired-heating steam methane reforming (f-SMR), e-SMR consumes less natural gas, has a higher energy efficiency of 78.7%, lower net CO2eq emissions, and captures CO2. However, it has a higher unit production cost of $3.49/kg H2. Overall, the study highlights the potential and economic viability of e-SMR. Rating: 8/10

Summary: This study compares the greenhouse gas emissions and economic feasibility of thermal decomposition of methane (TDM) technology and conventional steam methane reforming (SMR) technology for ammonia production. The results show that TDM has lower fuel consumption and emits less greenhouse gases than SMR. However, SMR has lower production costs and is more economically attractive. Integrating a carbon capture unit into TDM improves its economic performance when considering the sale of oxygen. SMR is more economically preferable without a carbon capture unit when the carbon price is below $99/t CO2, but above this price, integrating a carbon capture unit into TDM becomes economically preferable.

Summary: This study evaluates the technical, economic, and environmental performance of renewable methane production systems through techno-economic assessment and life-cycle assessment. It is found that scaling up the solid oxide electrolysis (SOE) system from 1 MW to 10 MW can lead to a significant reduction in methane production cost. However, at the current level, it is economically infeasible. Further research and improvement of the SOE system and a decrease in renewable electricity prices can potentially make renewable methane economically equivalent to conventional natural gas. Additionally, integrating low energy intensity energy resources with the SOE system for methane production can result in negative CO2 emissions and accelerate climate change mitigation.

Summary: Biomass use for energy and materials is a key mitigation option to reach the 1.5 degrees C global temperature target set in the Paris Agreement. However, negative connotations have emerged in certain parts of the EU, particularly regarding displacement effects in markets and land use. Despite this, strong evidence supports the use of sustainable biomass, and there are insights on how to avoid displacement issues. By utilizing better agricultural methods, restoring marginal and degraded lands, and adapting to climate change, biomass can contribute significantly to the future energy and material supply, with potential benefits for overall mitigation and the removal of CO2 from the atmosphere. It is recommended that future policies prioritize the synergy between biomass, energy transition, climate adaptation, agriculture, and land use, as this offers an opportunity to contribute to the European Green Deal and improve energy security.

Summary: Offshore wind is a rapidly growing low-carbon energy technology with fluctuating technology costs. This study used three quantitative methodologies to analyze the progress of offshore wind technology in the EU and UK, and examined the factors influencing cost development. The results showed that in the early stages, an increase in specific capital expenditure led to higher average generation costs, while in the upscaling and growth stage, a decrease in specific capital expenditure resulted in significant cost reductions. Recent cost declines were attributed to improved financing conditions, increased capacity factors, and decreased technology costs.
