With clean hydrogen emerging as a key component in reducing emissions in "hard-to-abate" sectors like steel-making and the chemical industry, a better understanding of its water footprint is becoming increasingly important.

How do you solve green hydrogen's water problem? 💧   One of the main concerns raised about the rollout of hydrogen produced by electrolysis is the high water consumption required. For each kilogram of hydrogen produced by electrolysis, a theoretical requirement of 9 litres of deionised water is required. In practice, most electrolyser systems on the market will require between 10 and 11 litres of water per kilogram of hydrogen produced. Based on this, in the worst-case scenario, achieving just the EU's green hydrogen production target will require 110 million litres of water. At a global level, this figure becomes even more incomprehensible. The growth of hydrogen electrolysis could present massive problems in water scarce regions.   💡 One potential solution, as the diagram below shows, is to site electrolysis facilities near the sea and use desalination plants, i.e. produce freshwater for electrolysis using seawater. Contrary to what one might expect, this would require just ~0.14% more energy per kilogram of hydrogen produced when compared with using clean freshwater.   Data sources: Water required for H2 production: Water for the Hydrogen Economy - https://lnkd.in/e-pyHpyM Energy required to purify water: Silhorko-Eurowater A/S - https://lnkd.in/eKvbNfRH

Hydrogen is getting a lot of attention lately as a green energy option, but transporting it comes with a host of challenges. Using amonia as a "carrier" for #hydrogen can potentially address some of the issues. A new white paper from the World Business Academy examines this topic: https://lnkd.in/grApXph2

Did you know hydrogen is colour-coded according to the source it is extracted from? In an effort to understand its production and reach their environmental, social and governance goals, interest in categorising hydrogen has increased over the years.

A couple of exciting papers have recently been published that used SilcoTek Corporation's coatings to better understand #catalysis in both ammonia storage/conversion to hydrogen as well as in producing green aviation fuels from wet waste. Read on for more information: The first article came out of a collaboration between the Max Planck Institute for Chemical Energy Conversion, the Laboratory of Industrial Chemistry at Ruhr University Bochum, and the Fritz-Haber-Institut der Max-Planck-Gesellschaft in April. Martin Muhler and his team were looking at developing a system to determine catalyst lifetimes as it was largely overlooked in the literature, but is a crucial variable to account for in hydrogen production from ammonia: https://lnkd.in/eDmEsNQF The second comes from the Catalytic Carbon Transformation and Scale-up Center and the Center for Integrated Mobility Sciences at the National Renewable Energy Laboratory. Jacob Miller and his group looked at converting wet waste-derived volatile fatty acids into sustainable aviation fuel (SAF): https://lnkd.in/eB326-6c I was unaware of just how much wet waste is produced here in the States: "Wet waste is generated in the United States with energy content equivalent to 10.5 billion gallons per year [of] aviation fuel, enough to satisfy 30% of the projected 2050 SAF demand." And not only can this process contribute to the demands of aviation fuels, it can create benzene, toluene, ethylbenzene, and xylene (BTEX) which are critical for a variety of chemical processes and are largely made from fossil fuels. In these studies, the researchers wanted to minimize any unwanted catalytic activity with the reactor walls (both made of stainless steel). For the ammonia decomposition catalyst, #Silcolloy was chosen as the coating due to its previous success in ammonia stability applications: https://lnkd.in/eU7-GTnV For the aviation fuels study, #Dursan was the coating of choice, again, based on previous studies for this very application: https://lnkd.in/e7qAg5kP Our corporate vision is "A better world through SilcoTek coatings". Addressing climate change and making catalytic conversions more efficient and sustain able are a perfect example of doing just that. Making the world a better place.

#greenhydrogen ♻️ Green hydrogen is produced through a process called electrolysis, which involves using electricity to split water (H2O) into hydrogen (H2) and oxygen (O2). Here's a step-by-step explanation of how electrolysis is used to produce green hydrogen: 1. Water Source: The process begins with a source of water, which can be freshwater or seawater. 2. Electrolyzer: An electrolyzer is the device used for electrolysis. It consists of two electrodes—an anode and a cathode—separated by an electrolyte. The electrolyte can be a solid, liquid, or polymer membrane that allows ions to pass through. 3. Power Source: A renewable energy source, such as solar or wind power, is used to generate electricity. This electricity is then supplied to the electrolyzer. 4. Electrolysis: When electricity is applied to the electrolyzer, it creates an electric current that flows between the electrodes. The electrodes are made of conductive materials, such as titanium or stainless steel, and each electrode has a specific charge. - Anode: The anode, typically positively charged, attracts negatively charged ions (anions) from the water, primarily hydroxide ions (OH-). At the anode, water molecules lose electrons and release oxygen gas (O2). - Cathode: The cathode, usually negatively charged, attracts positively charged ions (cations) from the water, primarily hydrogen ions (H+). At the cathode, hydrogen ions gain electrons and form hydrogen gas (H2). - Electrolyte: The electrolyte helps facilitate the movement of ions between the anode and cathode while preventing the mixing of hydrogen and oxygen gases. 5. Collection and Purification: The hydrogen gas produced at the cathode is collected and purified to remove any impurities or traces of oxygen. This ensures that the resulting hydrogen is of high purity and suitable for various applications. The key to producing green hydrogen is using renewable energy as the power source for the electrolysis process. By utilizing carbon-free electricity from renewable sources, such as solar or wind, the overall process becomes environmentally friendly and avoids the emissions associated with traditional hydrogen production methods that rely on fossil fuels. It's worth noting that electrolysis can be performed at different scales, from small-scale applications to large industrial operations, depending on the intended use and demand for green hydrogen.
