December 27, 2017 Researchers at Columbia University have developed the first demonstration of a practical, floating, membrane-free and pump-free photovoltaic-driven electrolysis device. The device consists of platforms of solar-powered electrolyzers floating on the sea to generate hydrogen fuel. It uses electrodes made of sheets of titanium mesh suspended in water. … Continue reading

Mass Production of Hydrogen Needed
October 21, 2017 Rapidly melting glaciers in northwestern China and throughout the world are expected to disappear completely within the next 50 years, a global catastrophe in the making. They are in some cases the principal source of water (the other being groundwater which is also being rapidly depleted) for … Continue reading
Hydrogen Exports as a Specific Special Drawing Rights (SDR) Criterion
January 29, 2019 Western Reserve Currencies and the Quest for Dominance Historically, shifts in reserve currencies have brought pivotal changes in the global balance of power. Beginning with the 15th Century, which marked Western Europe’s global ascendancy, the currencies of the empires of Portugal (1450-1530), Spain (1530-1640), the Netherlands (1640-1720), … Continue reading
Solar-powered Photocatalytic Water Splitter
May 7, 2017 China’s University of Science and Technology reports that using solar energy to produce hydrogen and oxygen from water is a sustainable technology. A research group led by Professor Xiong Yujie has developed a class of noble-metal-free Z-scheme photocatalysts which exhibit an enhanced performance in photocatalytic hydrogen production … Continue reading
Biodegradable Hydrogen Catalyst 150 Times More Efficient
January 6, 2016 Scientists at Indiana University Bloomington have created a biodegradable, easy to mass-produce catalyst called P22-Hyd consisting of a modified enzyme (hydrogenase) protected within the protein shell of a bacterial virus. The material forms a nano-reactor that catalyzes hydrogen formation 150 times more efficiently than the enzyme would … Continue reading
Swiss Water Splitter – 2014
December 8, 2014 The ongoing worldwide effort to improve the efficiency of using solar energy to split water to produce hydrogen -electrolysis- has added a new milestone. Scientists from Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland have achieved a solar energy to hydrogen conversion efficiency of 12.3 percent using … Continue reading

Stanford University Water Splitter
Stanford scientists develop water splitter that runs on an ordinary AAA battery Aug. 22, 2014 By Mark Shwartz In 2015, American consumers will finally be able to purchase fuel cell cars from Toyota and other manufacturers. Although touted as zero-emissions vehicles, most of the cars will run on hydrogen made … Continue reading
Conversion Factors
Specific equations available here Various measures, conversions and definitions used for hydrogen systems STP = standard temperature/pressure = 0°C (32°f) and 1 bar (≈1 atmosphere).Some references say STP is 25°C (77°f), reason unknown.NTP = normal temperature/pressure = 20°C (68°f) and 1 atm (atmosphere). Functionally, NTP is almost the same as … Continue reading
Advanced Hydrogen Turbine
Background Siemens Energy, along with numerous partners, has an ongoing U.S. Department of Energy (DOE) program to develop hydrogen turbines for coal-based integrated gasification combined cycle (IGCC) power generation that will improve efficiency, reduce emissions, lower costs, and allow for carbon capture and storage (CCS). Siemens Energy is expanding … Continue reading
