Safe use of hydrogen for lab and pilot scale

The purpose of this document is to supply necessary information for safe handlingof hydrogen for lab and pilot scale applications of HARARE project. Whenhydrogen is oxidized with oxygen, the only by-product is water vapor, making itan ideal energy carrier and oxidizing agent for a green environmentally friendlyand sustainable economy. Hydrogen is however commonly viewed as […]

Working with hydrogen gas

Working with hydrogen gas Meet Esin! Esin Iplik is a phd-student at Linde. She works with hydrogen, a highly flammable gas that burns with an almost invisible flame! More specific she is working on hydrogen oxyfuel combustion (combustion of hydrogen with pure oxygen instead of air) at the combustion lab in Unterschleißheim – Linde Technology […]

Fun facts about hydrogen transportation

Fun facts about hydrogen transportation: This huge truck contains only 395 kg of hydrogen, but that is actually a lot of hydrogen!! Linde transports hydrogen in huge trucks. The volume of hydrogen is 4,400 Nm3, which corresponds to 1.76 Olympic swimming pools at normal conditions. However, hydrogen is transported under 200 bar pressure. This corresponds […]

How to extract iron from Red Mud

How to extract iron from Red Mud Meet Arman H Kermani (to the right) and Per Ivar Friborg (to the left) from NTNU doing small scale experiments at a SINTEF facility. The aim of these experiments, conducted by Arman, is to be able to reduce red mud with hydrogen, producing iron. Red Mud is a […]

Hydrogen as reductant – What does that mean?

Hydrogen as reductant – What does that mean?   Metals exist in the earth’s crust mainly as oxides. It means that every metal atom is attached to one or more oxygen atoms. They form very strong bound, like a marriage. To break these bounds, we need a reductant to steal the oxygen atoms from the metal atoms. Normally carbon is used […]

Let’s talk about Red Mud (Bauxite Residue)

Let’s talk about Red Mud (Bauxite Residue) Global annual production of red mud (bauxite residue) is about 150 million tonnes. It contains raw materials for the production of iron, silicon and aluminium, and is dumped as waste in spite of the availability of recycling technologies. This is because it is cheaper to dump bauxite residue as […]
