Natural gas as a generating source in the diversification of the Brazilian electric matrix Autores Mariana Vieira Barcelos Generoso Universidade Federal do Espírito Santo Ana Paula Meneguelo Universidade Federal do Espírito Santo https://lnkd.in/ddqKkgC3 DOI: https://lnkd.in/dBiaTcwd Palavras-chave: gás natural, eletricidade, incentivos Resumo Energy consumption grows annually, requiring an increase in the production and distribution standards of available energy sources. One of the main energy consumptions is linked to the electricity sector, which is globally dependent on fossil fuels such as oil and coal. In Brazil, more than 60% of electricity consumption comes from hydroelectric plants, and the lack of variability in generating sources generates instability and energy insecurity in the country. In this sense, it is necessary to evaluate an alternative source of electricity that can work together with hydroelectric plants and guarantee the stability of generation. Natural gas presents itself as an alternative, as it is a safe source and less aggressive to the environment when compared to other non-renewable sources. Through data collection and bibliographic research on proven reserves, processing capacity, and distribution of natural gas, this work analyzed the Brazilian potential for the use of natural gas and the biggest gaps in the sector. The results showed that, despite the great potential in proven natural gas reserves, Brazil is stagnant in its processing and distribution capacity. In addition, there are challenges related to high rates and taxes on the use of natural gas.

QIMC and INRS Announce Expansion to 9kms of Significant Anomalous Natural Hydrogen Soil Gas Discovery at Ville Marie Project August 06, 2024 9:02 AM EDT | Source: Quebec Innovative Materials Corp. Lachute, Quebec--(Newsfile Corp. - August 6, 2024) - Quebec Innovative Materials Corp. (CSE: QIMC) (FSE: 7FJ) ("QI Materials", "QIMC" or the "Company"), Quebec Innovative Materials with its partner the Institut National de la Recherche Scientifique (INRS), is proud to announce that our recent exploration has extended the discovery of significant anomalous natural hydrogen soil gas to lines 4 and 5, marking an important milestone that supports Quebec's clean energy agenda and low carbon emissions targets. "This significant extension of our discovery to 9kms to the south of Line 1, combined with the large zones of strong anomalous soil samples exceeding 300 ppm in Line 5, highlights the district-wide natural hydrogen potential of the Ville Marie project. This development plays a crucial role in Quebec's transition towards a more sustainable and renewable energy future," comments John Karagiannidis, CEO of QIMC. Following the surveys on Lines 1 to 3, QIMC and INRS continued soil gas surveys south of the town of St-Bruno-de-Guigues to verify the extent of hydrogen anomalous zones or domains. The new lines 4 and 5 are located 6.9 and 9.2 km south of line 1, respectively (Figure 1). Data from lines 4 and 5 show numerous large continuous anomalies above 300 ppm hydrogen (Figure 2).

At Virginia Tech, researcher Rohit Pandey is benefiting from the Biden administration's initiative to enhance hydrogen infrastructure, which includes over $7 billion in funding. Pandey has been awarded $1.5 million to investigate underground hydrogen storage in Appalachia’s depleted gas reservoirs, a project that aims to boost energy independence and foster regional job growth. This initiative positions the area to become a leading producer of hydrogen, leveraging existing infrastructure to store hydrogen both economically and securely. Pandey's work will test the feasibility of this storage method and develop strategies to mitigate risks such as hydrogen leakage. This project not only supports Appalachia’s transition to cleaner energy but also serves as a model for hydrogen storage globally.

🔬 Sandia National Laboratories is leading research into subterranean storage solutions for hydrogen, recognizing its importance in the transition to a carbon-free energy landscape. 💡 Key Insights from the Research: 🌱 Under the leadership of Ho Tuan, a chemical engineer at Sandia, researchers delve into repurposing depleted oil and natural gas reservoirs as potential sites for storing hydrogen. 🌱 This initiative is driven by the understanding of hydrogen's significance in facilitating the integration of renewable energy sources and overcoming the intermittent nature of solar and wind power. 🌱 Sandia addresses hydrogen's challenges - low energy density and compression issues - hindering traditional storage methods. However, their focus on porous formations, like sandstone and shale, unveils promising hydrogen retention capabilities. 🌱 Sandia's research also meticulously addresses contamination risks, particularly from residual natural gas within the reservoirs. #HydrogenStorage #CleanEnergy #RenewableEnergy #SandiaResearch #EnergyTransition #Decarbonization #Innovation #PorousFormations #Sandstone #Shale #SustainableEnergy #ClimateAction

Some energy news and updates. This figure shows that seasonal energy storage will be an essential element of the energy transition. The top graph shows the 6-month electricity generation mix for Germany (source: Fraunhofer Institute). The bottom graph shows what's happening in November 2024. November deviates significantly from the average mix in favor of fossil fuels. This is due to a two-week deficit in wind and solar power, which was covered by natural gas-fired generation. Seasonal storage will be needed to make up for such a shortfall when fossil fuel generation is no longer available in the future. Unlike meeting daily peaks, longer-term energy storage may require a different set of technologies, such as flow batteries, or an energy carrier, such as hydrogen. At first glance, there are many startups developing flow battery solutions. However, the recent troubles of Redflow ltd, an Australian developer of medium to long-term energy storage based on zinc bromide flow batteries, show that the emerging market for long-term energy storage is still very thin. Too thin to generate revenue and attract investors: https://lnkd.in/eZZS_Egx Underground hydrogen storage can also be used for this purpose, but much of the work being done today is really theoretical techno-economic analysis: https://lnkd.in/efG3VSWM Germany is one of the very few actors working on a real demo project https://lnkd.in/emyXmKTj Underground storage is also one of the areas where petroleum engineering can make a difference for a sustainable future. Oilfield service companies have the expertise to study different large-scale storage options in geological structures, be it salt caverns or porous media (depleted hydrocarbon reservoirs or saline aquifers). #hydrogen #SLB #Halliburton #energytransition

Team explores the subterranean storage of hydrogen. Imagine a vast volume of porous sandstone reservoir, once full of oil and natural gas, now full of a different carbon-free fuel—hydrogen. Scientists at Sandia National Laboratories are using computer simulations and laboratory experiments to determine whether depleted oil and natural gas reservoirs can be used for storing this carbon-free fuel. Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and power heavy industry, and it could be used to power fuel-cell-based vehicles. Additionally, hydrogen could be stored for months and used when energy needs outpace the supply delivered by renewable energy sources.

This is one I’ll watch. An #iron air #battery that will discharge at grid scale for 100 hours. Quote: “We are targeting around 100 hours of storage so we can actually bridge longer gaps of renewable power generation,” Yilmaz told TechCrunch. “The more renewables that you have in the grid, the longer duration that you will need.” Ore Energy’s core technology was spun out of TU Delft in the Netherlands, where Yilmaz researched corrosion as part of his PhD and postdoc. The batteries release energy by rusting iron and store it by reversing that corrosion. Unlike other batteries that are shipped with all the necessary chemicals inside, Ore Energy’s do not. Instead, they draw one of their key reactants, oxygen, from the atmosphere. Hence the name: iron-air battery. “The batteries are actually inhaling and exhaling oxygen, and that is what allows these reactions to happen,” Yilmaz said. I live in #westernaustralia - which provides around 39% of the annual global supply of iron ore. That 39% was 919 million tonnes (2023). We also provide 47% of the global supply of lithium concentrate - that 47% was 61,000 tonnes (2022). Lithium ion batteries currently dominate the technology used in large grid scale battery arrays. Maybe iron is next? Massive #transition multipliers right here.
