“…As a numerical example that correlates with the qualitative presentation in Fig. 8 , a performance assessment by Zomer et al ( 2020 ) of PV systems installed at a positive energy building is considered here. The building is the Fotovoltaica/UFSC solar energy laboratory ( http://www.fotovoltaica.ufsc.br ) in Florianópolis, Brazil (27° S, 48° W).…”

Energy sustainability is a key consideration for anthropogenic activity and the development of societies, and more broadly, civilization. In this article, energy sustainability is described and examined, as are methods and technologies that can help enhance it. As a key component of sustainability, the significance and importance of energy sustainability becomes clear. Requirements to enhance energy sustainability are described, including low environmental and ecological impacts, sustainable energy resources and complementary energy carriers, high efficiencies, and various other factors. The latter are predominantly non-technical, and include living standards, societal acceptability and equity. The outcomes and results are anticipated to inform and educate about energy sustainability, to provide an impetus to greater energy sustainability.

“…A design assessment of energy generation using solar photovoltaic (PV) and wind systems in different climate zones found that solar PV is a reliable and stable onsite renewable energy system not only in the present time but also into the future as the energy output is expected to increase (Shen & Lior, 2016). Another NPEB case study reports that 65% of onsite energy generation was used for building energy consumption, while the remaining 35% was used to charge electric vehicles (Zomer et al, 2020). In a techno-economic and environmental assessment for a solar PV system, it was reported that a 1MW system would meet a campus's energy needs and generate revenue by selling the energy back to the grid (Paudel et al, 2021).…”

Net-Positive Energy Buildings: Empirical Insights Towards Achieving the SDGs

Buildings impact multiple United Nations (UN) Sustainability Development Goals (SDGs). Net-positive energy buildings (NPEBs) present an opportunity for the built sector to offer climate solutions and habitable environments with improved energy efficiency, responsible consumption, sustainable energy production, and sustainable communities. Case study analysis of a multi-tenant office NPEB demonstrates decisions made to realize the SDGs. Average annual energy consumption of 83 kWh/m 2 was one-third that of typical office buildings and the generation of 871 kWh of solar electricity achieved the net-positive goal. This mixed methods performance assessment used four years of energy meter data and key informant interviews to provide a holistic understanding of building energy performance and contributions to the SDGs.

“…H 2 production is frequently driven by renewable and non-renewable energy resources, such as fossil fuels— in particular steam methane reforming [ 8 , 9 ] and the NAFTA reform [ 10 , 11 ]—from biomass [ 12 ], and from biological sources [ 13 , 14 , 15 , 16 ]. Unfortunately, these H 2 production methods are expensive, partially efficient, and environmentally polluting, as well as also producing low-purity H 2 [ 17 , 18 , 19 , 20 ]. Meanwhile, the unique way to produce the cleanest H 2 is from the well-known process of water electrolysis or, as commonly called, water splitting.…”

“…In this sense, the key to overcoming this economic obstacle is to supply the electrical energy for the electrochemical cell by using renewable energy sources, such as wind or solar power [ 17 , 18 ]. In Brazil, the abundance of resources that exceed demand, high solar irradiation, and consistent wind parks are a list of Brazil’s competitive advantages for producing green H 2 using renewable energy [ 19 , 20 ].…”

Photovoltaic Electrochemically Driven Degradation of Calcon Dye with Simultaneous Green Hydrogen Production

et al. 2022

In this study, for the first time, the production of green hydrogen gas (H2) in the cathodic compartment, in concomitance with the electrochemical oxidation (EO) of an aqueous solution containing Calcon dye at the anodic compartment, was studied in a PEM-type electrochemical cell driven by a photovoltaic (PV) energy source. EO of Calcon was carried out on a Nb/BDD anode at different current densities (7.5, 15 and 30 mA cm−2), while a stainless steel (SS) cathode was used for green H2 production. The results of the analysis by UV-vis spectroscopy and total organic carbon (TOC) clearly showed that the electrochemical oxidation (EO) of the Calcon dye after 180 min of electrolysis time by applying 30 mA cm−2 reached up to 90% of degradation and 57% of TOC removal. Meanwhile, under these experimental conditions, a green H2 production greater than 0.9 L was achieved, with a Faradaic efficiency of 98%. The hybrid electrolysis strategy is particularly attractive in the context of a circular economy, as these can be coupled with the use of more complex water matrices to transform organic depollution into an energy resource to produce H2 as a chemical energy carrier.
