BLUE HYDROGEN Blue hydrogen is derived from natural gas through the process of steam methane reforming (SMR). SMR mixes natural gas with very hot steam, in the presence of a catalyst, where a chemical reaction creates hydrogen and carbon monoxide. Additional water is added to the mixture converting the carbon monoxide to carbon dioxide and creating more hydrogen. The carbon dioxide emissions produced are then captured and stored underground using Carbon Capture, Utilization and Storage (CCUS) technology leaving nearly pure hydrogen. Blue H2 facts: • The most common and economical way to produce hydrogen • When used with CCUS, blue hydrogen produces nearly zero emissions • Alberta has the infrastructure to produce blue hydrogen cheaper than any other jurisdiction in the world Natural Gas Pure Hydrogen Hydrogen and Hydrogen and remains Carbon Monoxide Carbon Dioxide are formed are formed Steam Steam CO2 removed, transported and permanently stored 5468 GREEN HYDROGEN Green hydrogen is the production of hydrogen from renewable energy through electrolysis. It is a process that splits water into its basic elements – hydrogen and oxygen – using an electric current. The electricity used in the process comes from renewables. Green H2 facts: • Most expensive method for producing hydrogen • Producing hydrogen generates zero emissions • Electrolysis can be powered by renewable energy such as wind, hydropower and solar energy Clean water is pumped into the electrolyser The water is split by an electric charge into hydrogen and oxygen O2 The oxygen is released H2 into the atmosphere or utilized H2O The hydrogen is captured 5468.

An Alternate Graphical Representation of Periodic Table of Chemical Elements Mohd Abubakr1, Microsoft India (R&D) Pvt
An Alternate Graphical Representation of Periodic table of Chemical Elements Mohd Abubakr1, Microsoft India (R&D) Pvt. Ltd, Hyderabad, India. [email protected] Abstract Periodic table of chemical elements symbolizes an elegant graphical representation of symmetry at atomic level and provides an overview on arrangement of electrons. It started merely as tabular representation of chemical elements, later got strengthened with quantum mechanical description of atomic structure and recent studies have revealed that periodic table can be formulated using SO(4,2) SU(2) group. IUPAC, the governing body in Chemistry, doesn‟t approve any periodic table as a standard periodic table. The only specific recommendation provided by IUPAC is that the periodic table should follow the 1 to 18 group numbering. In this technical paper, we describe a new graphical representation of periodic table, referred as „Circular form of Periodic table‟. The advantages of circular form of periodic table over other representations are discussed along with a brief discussion on history of periodic tables. 1. Introduction The profoundness of inherent symmetry in nature can be seen at different depths of atomic scales. Periodic table symbolizes one such elegant symmetry existing within the atomic structure of chemical elements. This so called „symmetry‟ within the atomic structures has been widely studied from different prospects and over the last hundreds years more than 700 different graphical representations of Periodic tables have emerged [1]. Each graphical representation of chemical elements attempted to portray certain symmetries in form of columns, rows, spirals, dimensions etc. Out of all the graphical representations, the rectangular form of periodic table (also referred as Long form of periodic table or Modern periodic table) has gained wide acceptance.

Word Bank: Adhesion Evaporation Polar Surface tension Cohesion Freezing Positive Universal solvent Condensation Melting Sublimation Dissolve Negative 1. The electrons are not shared equally between the hydrogen and oxygen atoms of water creating a Polar molecule. 2. The polarity of water allows it to dissolve most substances. Because of this it is referred to as the universal solvent 3. Water molecules stick to other water molecules. This property is called cohesion. 4. Hydrogen bonds form between adjacent water molecules because the positive charged hydrogen end of one water molecule attracts the negative charged oxygen end of another water molecule. 5. Water molecules stick to other materials due to its polar nature. This property is called adhesion. 6. Hydrogen bonds hold water molecules closely together which causes water to have high surface tension. This is why water tends to clump together to form drops rather than spread out into a thin film. 7. Condensation is when water changes from a gas to a liquid. 8. Sublimation is when water changes from a solid directly to a gas. 9. Freezing is when water changes from a liquid to a solid. 10. Melting is when water changes from a solid to a liquid. 11. Evaporation is when water changes from a liquid to a gas. 12. Why does ice float? Water expands as it freezes, so it is LESS DENSE AS A SOLID. 13.

Lithium Hydride Powered PEM Fuel Cells for Long-Duration Small Mobile Robotic Missions
Lithium Hydride Powered PEM Fuel Cells for Long-Duration Small Mobile Robotic Missions Jekanthan Thangavelautham, Daniel Strawser, Mei Yi Cheung Steven Dubowsky Abstract— This paper reports on a study to develop power supplies for small mobile robots performing long duration missions. It investigates the use of fuel cells to achieve this objective, and in particular Proton Exchange Membrane (PEM) fuel cells. It is shown through a representative case study that, in theory, fuel cell based power supplies will provide much longer range than the best current rechargeable battery technology. It also briefly discusses an important limitation that prevents fuel cells from achieving their ideal performance, namely a practical method to store their fuel (hydrogen) in a form that is compatible with small mobile field robots. A very efficient Fig. 1.

Xenon in Earth's Atmosphere Is Severely Mass Fractionated and Depleted Compared to Any Plausible Solar System Source Material, Yet Kr Is Unfractionated
Xenon Fractionation, Hydrogen Escape, and the Oxidation of the Earth Xenon in Earth's atmosphere is severely mass fractionated and depleted compared to any plausible solar system source material, yet Kr is unfractionated. These observations seem to imply that Xe has escaped from Earth. But to date no process has been identified that can cause Xe, which is heavier than Kr, to escape while Kr does not. Vigorous hydrodynamic hydrogen escape can produce mass fractionation in heavy gases (Hunten et al. 1987, Sasaki & Nakazawa 1988, Pepin 1991). The required hydrogen flux is very high but within the possible range permitted by solar Extreme Ultraviolet radiation (EUV, which here means radiation at wavelengths short enough to be absorbed efficiently by hydrogen) heating when Earth was on the order of 100 Myrs old or younger. However this model cannot explain why Xe escapes but Kr does not. Recently, what appears to be ancient atmospheric xenon has been recovered from several very ancient (3-3.5 Ga) terrestrial hydrothermal barites and cherts (Pujol 2011, 2013). What is eye-catching about this ancient Xe is that it is less fractionated that Xe in modern air. In other words, it appears that a process was active on Earth some 3 to 3.5 billion years ago that caused xenon to fractionate. By this time the Sun was no longer the EUV source that it used to. If xenon was being fractionated by escape — currently the only viable hypothesis — it had to be in the less unfamiliar context of Earth’s Archean atmosphere and under rather modest levels of EUV forcing.

Water Molecules and Surface Tension Water Holds Unique Properties Which Makes It "Sticky" at the Surface
Water Molecules and Surface Tension Water holds unique properties which makes it "sticky" at the surface. Each individual water molecule has one large oxygen atom and two smaller hydrogen atoms. The hydrogen atoms hold a slightly positive charge, making the entire water molecule polar. Like tiny magnets, the hydrogen atoms attract the oxygen atoms from other water molecules, creating temporary hydrogen bonds within the water. Each water molecule experiences a pull from other water molecules from every direction, but water molecules at the surface do not have molecules above the surface to pull at them. These water molecules have more pull from the water below than the surface above. This difference in force packs the water molecules at the surface closer together than they are inside the liquid. The thin, dense layer of molecules produces the phenomenon called surface tension. VARIABLE: SOAP Detergent and Water Detergent and soap are similar chemically, except for the oil in them. Many soaps use natural fats. Soap and detergent molecules have two ends which act as a bridge between water molecules and grease (fat) molecules. One end is called hydrophilic- water loving which is the head of the molecule; the other end is hydrophobic- water fearing, which is the tail part of the molecule. This allows the soap or detergent to grab onto the grease from a dirty dish and use the other end of the detergent molecule to latch on to water to be washed away. When the grease and dirt is collected in the soap, a micelle is created. Detergent and Soap Break Surface Tension Detergent molecules' two ends make it able to break through the surface tension of water.

Options for Producing Low-Carbon Hydrogen at Scale
Options for producing low-carbon hydrogen at scale POLICY BRIEFING POLICY BRIEFING Politics and science frequently move on vastly different timescales. A policymaker seeking evidence on a new policy will often need the answer in weeks or months, while it takes years to design and undertake the research to rigorously address a new policy question. The value of an extended investigation into a topic cannot be understated, but when this is not possible good evidence is better than none. The Royal Society’s series of policy briefings is a new mechanism aiming to bridge that divide. Drawing on the expertise of Fellows of the Royal Society and the wider scientific community, these policy briefings provide rapid and authoritative syntheses of current evidence. These briefings lay out the current state of knowledge and the questions that remain to be answered around a policy question often defined alongside a partner.

Recovery of Hydrogen and Helium from Their Mixtures Using Metal Hydrides
RECOVERY OF HYDROGEN AND HELIUM FROM THEIR MIXTURES USING METAL HYDRIDES by MUZAFFER TONGUC OZTEK B.S. Middle East Technical University, 1999 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in the Department of Chemistry in the College of Arts and Sciences at the University of Central Florida Orlando, Florida Summer Term 2005 © 2005 Muzaffer Tonguc Oztek ii ABSTRACT Waste streams of hydrogen and helium mixtures are produced at the Kennedy Space Center during purging of the hydrogen systems and supply lines. This process is done prior to and after hydrogen servicing. The purged waste gases are lost to the atmosphere, resulting in an annual loss of 2 million and 0.1 million standard cubic meters of helium and hydrogen, respectively. Recovery of these gases will have an economic benefit. Metals, alloys, and intermetallics are known to react with hydrogen in favorable conditions; therefore, they have the possibility of serving as separating and recovery agents. In this study, Mg2Ni, VTiNi and LaNi5 were studied for the separation of H2 from He, using differential scanning calorimetry and thermal volumetric analysis. The ability of LaNi5 to react with hydrogen reversibly at room temperature was verified, and further analysis focused on this compound. Size reduction and activation of LaNi5 by mechanical milling was investigated using different milling parameters for the purpose of activating the material for hydrogen absorption. Because it has been shown that addition of aluminum to LaNi5 resulted in improved hydriding and dehydriding properties, that system was studied further here. In this study, aluminum was added to LaNi5 by mechanical milling.
