There’s no point ramping up hydrogen if other resource constraints are going to bring it to a halt. Here, Herib Blanco at IRENA summarises their research into how much water will be needed in the production of hydrogen through electrolysis (i.e. from water) and the costs involved. A wide range of analyses have been reviewed to calculate the amount of water used during the hydrogen production, and by the energy source used to power it (renewables … [Read more...]
New research into Catalysts can boost Hydrogen manufacture
Catalysts are materials used to enable and accelerate a chemical reaction. There is a long history of using them in industry to manufacture different hydrocarbons, ammonia, sulfuric acid, and the list goes on. By choosing your materials well and tinkering with the structure at the molecular level, the catalyst can greatly improve the efficiency of the conversion process. Glennda Chui at the SLAC National Accelerator Laboratory describes how their … [Read more...]
Energy sector is one of the largest consumers of water in a drought-threatened world
The implications of the global water footprint of energy generation are phenomenal, writes Gary Bilotta of the University of Brighton. He warns that if policy makers fail to take into account the links between energy and water, we may come to a point in many parts of the world where it is water availability that is the main determinant of the energy sources available for use.
