What one sees in you tube is explained below. I do not know how many can understand so easily. But a theory is in vogue; some are already graphited. Yet results are not seen as highly successful, as Input is costlier and output is yet to be convincing. Even remarks below would show the pros and cons. Why hydrogen? Scientists who concluded that stars and the environments are the outcome of Hydrogen only, came out, at the time of BIG BANG, might have the answers for the sustainability. KR IRS 281122 1. Green hydrogen: green hydrogen, produced from water with renewable electricity, is a central pillar in the Europe. Industry already uses large amounts of hydrogen from fossil sources, with almost all of it from natural gas – the goal is to replace that with greener alternatives. As a by-product of increasing renewable electricity production, the use of green hydrogen <https://journeytozerostories.neste.com/innovation/hydrogen-hype-bubble-or-game-changer-decarbonization> can be stepped up, and Koskinen believes refining and steelmaking will be early adopters, followed by its use as transportation fuel in hydrogen cell vehicles. In addition, green hydrogen holds vast potential in the scaling up of e-fuels and other Power-to-X solutions. 2. Renewable fuels in transportation: Decreasing crude oil reliance in transportation is crucial, says Koskinen. This is an enormous challenge and all sustainable solutions are needed. Electrification is one important solution <https://www.neste.com/media/sustainable-mobility/what-is-sustainable-mobility>, but not only this will take time to scale up but also its uses in aviation and in long haul and heavy duty transportation remain limited – renewable fuels <https://www.neste.com/products/all-products/renewable-road-transport> that fit into existing infrastructure, and can be used in existing vehicles instead of requiring investments into new ones, offer an immediate solution to decrease the use of fossil fuels and cut down emissions. Continuous innovation around renewable raw materials required to make these sustainable fuels is essential if we are to be able to scale up their use to a point where the domination by fossil fuels can be overturned. Using underutilized residues or even wastes as raw materials and repurposing them for another aim is something Neste is at the forefront of – agricultural residues like straw and forestry residues, and municipal solid waste are abundant. They hold a great potential for the production of sustainable fuels and replacing crude oil. . It works by making fuels from renewable electricity and carbon dioxide, by using electrolysis to turn water into hydrogen. 3. Innovations in agriculture and food: Lab-grown meat that reduces the climate impact of cows’ methane emissions, and vertical farming that more efficiently uses both land and water resources are vital developments.“One-third of all greenhouse gas emissions comes from food production,”. “A major part of biodiversity loss is related to agriculture, and agriculture also uses 70% of the world’s fresh water.” And every time we grow vegetables in the ground, we take out carbon from the soil and reduce its fertility. 4. Chemical recycling of waste plastic: “Plastic recycling is a must for two reasons,” “One, it reduces the need to use new fossil resources in plastics production. And two, while plastics recycling can reduce plastics pollution, circulating the material in the plastics value chain multiple times can also reduce the carbon emissions resulting from incineration and the end of plastics’ life cycle.” Neste is also working to increase the proportion of renewable content in plastics. “It’s a beautiful concept in principle, if you think about it,” Even in a circular plastics economy, part of the plastics cannot be brought back to use by recycling. “But if you’re able to compensate for that part by producing plastics from renewable raw materials, ultimately you would be able to wholly replace fossil content with renewables in a plastic cycle,”. 5. Green energy storage solutions and battery technologies: Electrification and green electricity will replace fossil energy not only in the transportation sector, but also in the industry and living. “These sources of renewable electricity are not stable,”. “They’re changing hour by hour, minute by minute.” But hydrogen, particularly green hydrogen, offers a way to sustainably scale up green energy storage solutions, with many trials underway for hydrogen-powered planes as well as vehicles. Likewise, batteries are being developed, with innovation led by those creating electric vehicles who need long-distance storage and the scale of batteries associated with that. “The big challenge is the availability of minerals,” . But innovation is occurring here, too, with new ideas to reduce the use of minerals in batteries, or switching out rare earth minerals for more abundant, easily available alternatives. 6. Heavy industry DE fossilization: One-fifth <https://netzeroclimate.org/sectors/heavy_industry/#:~:text=Heavy%20industry%20represents%2022%25%20of,in%20the%20sector%20is%20needed.> of global carbon emissions come from heavy industry, according to the University of Oxford, which means that action in that sector has more impact than most. By its very nature heavy industry is one of the hardest sectors to wean off fossil fuels – to help keep global warming under control, the answer is to focus on the areas where carbon emissions can be significantly mitigated or avoided. “The possibilities for decarbonization depend on the type of industry and there are many different means ranging from green hydrogen, electrification and replacement of fossil raw materials with renewable ones, to carbon capture, utilization or storage (CCUS),” . 7 Innovative co-processing and retrofitting solutions are also in a key role to help transform major industrial assets, such as refineries, which typically have long operational lifetimes. Transforming these assets to accommodate renewable and circular raw materials is a way to accelerate change, benefiting from readily available refining experience and know-how. Co-processing of renewable and circular raw materials reduces dependency on fossil raw materials and increases the renewables capacity, enabling lower-emission products. Retrofitting selected units, or even major parts of refineries to produce renewable fuels and materials is another potential approach to utilize the existing asset. 8 Circular business models: Becoming more circular in business is the next big leap that will see us move away from the linear model.: “According to circular economy principles products should be designed for reuse, repair and recycle”.
