Summary: This paper examines the cost and efficiency dynamics of three prevalent Power-to-Gas technologies. Our results suggest that electrolytic hydrogen production costs will approach but not reach the U.S. Department of Energy's $1.0/kg target by 2030.

Summary: Power-to-Power is a process that stores surplus renewable power as chemical energy in the form of hydrogen. The round-trip efficiency, considering processes such as hydrogen production, storage, distribution, and power generation, can reach a maximum of 29%. However, there is still room for improvement in increasing the round-trip efficiency, particularly in hydrogen production and power generation.

Summary: A comprehensive study on CO2 methanation through process simulation, economic analysis, and LCA was conducted to determine the most practical pathway for green methane production. Based on itemized cost estimation and environmental impact assessment, H-2 production using AWE and wind power (scenario 2) was identified as the best pathway, followed by scenario 5 using PWE and wind power.

Summary: The study focuses on evaluating technical implementations, CO2 sources usability, and the mass deployment potential of Power-to-Gas technology, emphasizing the importance of ensuring a low price of surplus electricity. An approach to eliminate regulated electricity distribution fees by associating a methanation plant with the main CO2-producing plant is proposed. Additionally, the study evaluates the use of P-t-G as an auxiliary operation of a lignite-fired power plant, showing a potentially good return on investment.

Summary: The role of hydrogen in the energy transition has evolved over the years, and the current focus is on its versatility in aiding the transition to CO2 neutrality. However, strong political support and robust infrastructure design are necessary for the realization of the hydrogen economy. Multiple barriers need to be addressed, including technology development, infrastructure co-creation, policy, market design, and business model development. This article provides a comprehensive understanding of the elements in the hydrogen economy, its current state, and the gaps that need to be filled.

Summary: Increasing renewable power generation is a way to reduce carbon emissions in the power system. Hydrogen can be used as an energy vector in a Power-to-Power system to optimize the energy flow from renewables to users. The proposed Renewable Energy Community (REC) aims to involve users in energy management and promote local renewable energy development. The PtP hydrogen-based system introduced in this work, with the integration of RECs, significantly enhances users' self-sufficiency despite its economic unsustainability.

Summary: The study provides an optimistic outlook on using renewable power-to-X opportunities for blending, replacement, and gas-to-power for the transition to green hydrogen. Blending can be achieved with modest green premiums this decade, and long-term substitution for natural gas combustion is likely to represent an abatement cost of AUD 18/tCO(2)-e including transmission and storage.

Summary: In this study, the economic viability of integrating flexible electrolysis units to produce hydrogen in methanol synthesis processes is investigated. It is found that exploiting the dynamics of electricity markets can make hydrogen production cost-competitive, with the electricity cost nearly collapsing to zero when the electrolysis system is operated in flexible mode.

Summary: The intermittent nature of renewable energy sources requires energy storage to meet grid demand and balancing requirements. Green hydrogen is a chemical energy carrier that can store large amounts of energy for long periods and be used flexibly. This study examines the production of hydrogen from wind using desalination and electrolysis units, comparing proton exchange membrane and alkaline electrolyser units. The analysis considers the intermittency of wind and compares it with grid-bought electricity. A model is developed to determine the selling price required for profitability over 10 years. Two scenarios are considered: using energy from the grid for hydrogen production and owning a wind turbine with capital expenditure. The study finds that the price of hydrogen production from wind is comparable to natural gas-derived hydrogen at a larger scale, with cheaper production from the alkaline electrolyser.

Summary: The study shows that renewable electrolysis hydrogen produced in South Africa can be generated at the lowest cost and transported to Japan at the lowest cost as ammonia. With concessional finance support, the target price for ammonia transportation to Japan can be achieved by 2030, and the target price for gaseous hydrogen may be reached by 2040.
