“…Finally, some researchers have proposed local hydrogen storage to guarantee the annual self-sufficiency of buildings equipped with photovoltaic (PV) systems, to compensate the seasonal output, although acknowledging the very high investment costs related to fuel cells and hydrogen storage system [103].…”

The Role of Green and Blue Hydrogen in the Energy Transition—A Technological and Geopolitical Perspective

Hydrogen is currently enjoying a renewed and widespread momentum in many national and international climate strategies. This review paper is focused on analysing the challenges and opportunities that are related to green and blue hydrogen, which are at the basis of different perspectives of a potential hydrogen society. While many governments and private companies are putting significant resources on the development of hydrogen technologies, there still remains a high number of unsolved issues, including technical challenges, economic and geopolitical implications. The hydrogen supply chain includes a large number of steps, resulting in additional energy losses, and while much focus is put on hydrogen generation costs, its transport and storage should not be neglected. A low-carbon hydrogen economy offers promising opportunities not only to fight climate change, but also to enhance energy security and develop local industries in many countries. However, to face the huge challenges of a transition towards a zero-carbon energy system, all available technologies should be allowed to contribute based on measurable indicators, which require a strong international consensus based on transparent standards and targets.

“…Apparently, all plots show high grid consumption during the winter season. To address this problem, hybrid solutions for seasonal storage, such as hydrogen fuel-cell-based storage with PV-BESS, might significantly contribute to reducing grid usage; however, chemical to electrical conversion losses have also been reported [84]. Apparently, all plots show high grid consumption during the winter season.…”

“…It has been observed that winters create a renewable energy deficit, which is covered mostly by grid imported electricity. For attaining high self-sufficiency in winters, hybrid solutions such as PV-BESS with hydrogen fuel-cells [84] would hold substantial preference. Moreover, the achieved self-sufficiency targets of 78% in Evermore, 65% in Gen Y, and 40% at SHAC could be improved significantly by optimizing the system operation, especially through PV exports control, and also via utilization of battery storage during higher consumption periods.…”

Shared Solar and Battery Storage Configuration Effectiveness for Reducing the Grid Reliance of Apartment Complexes

2020

More than 2 million houses in Australia have installed solar photovoltaic (PV) systems; however, apartment buildings have adopted a low percentage of solar PV and battery storage installations. Given that grid usage reduction through PV and battery storage is a primary objective in most residential buildings, apartments have not yet fully benefited from installations of such systems. This research presents shared microgrid configurations for three apartment buildings with PV and battery storage and evaluates the reduction in grid electricity usage by analyzing self-sufficiency. The results reveal that the three studied sites at White Gum Valley achieved an overall self-sufficiency of more than 60%. Owing to the infancy of the shared solar and battery storage market for apartment complexes and lack of available data, this study fills the research gap by presenting preliminary quantitative findings from implementation in apartment buildings.

“…Photovoltaic and other solar systems depend on solar radiation and ambient temperature, wind turbines depend on wind direction, and hydroelectric plants depend on river flow. However, there are cases where the aforementioned renewable sources cannot provide the required amount of electricity, so the use of fuel cells becomes a good solution to the aforementioned problem because the cells are not dependent on weather conditions [ 21 ].…”

“…With the fuel cell output, the system can operate when there is no sun exposure or when the batteries are not in optimal function. The hydrogen is stored in a tank, and, when it passes into the cell, it is recombined with oxygen, and electricity is generated [ 21 ].…”

Bio-Inspired Electricity Storage Alternatives to Support Massive Demand-Side Energy Generation: A Review of Applications at Building Scale

This work has its origin in the growing demands of energy regulations to meet future local targets and to propose a global implementation framework. A literature review related to conventional electrical energy storage systems has been carried out, presenting different cases analyzed at building scale to deepen in nature-inspired processes that propose reductions in environmental impact and present improvements in these storage devices. The use of batteries, especially lithium-ion batteries, is the most prominent among the electrical storage applications; however, improvements have been proposed through hydrogen batteries or the implementation of more environmentally friendly materials to manufacture the electrodes. In this sense, oriented to creating systems designed to protect the environment, important advances have been made in the development of storage systems based on biomimetic strategies. The latter range from the generation of energy through the respiratory processes of microorganisms to the recreation of the generation, storage, and release of energy using the thermoelectric and thermoregulatory characteristics of some insects. These facts show that the trend in research towards improving existing systems continues but reinforces the idea that new solutions must be environmentally friendly, so there is still a long way to improving the processes established thus far.
