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...]
Nuclear-Wind hybrid plants for grid stability, Power-to-X and more
How would you use a nuclear-wind hybrid plant and maximise its potential? When intermittent wind’s output falls, nuclear can step in to feed the grid. When it’s not doing that it can use its power to run the production of a wide range of commodities: from biofuels, hydrogen, pumped hydro to wastewater purification, desalination, chemical manufacturing and more – including straightforward thermal power for industry. In collaboration with NREL, the … [Read more...]
Unlocking the potential of Ocean Energy: from megawatts to gigawatts
When you consider the expanse of the world’s oceans no one should be surprised that the theoretical potential for electricity generated from ocean energy is several times total global energy demand. Of course, that potential needs to be harnessed at commercial prices. Francisco Boshell, Roland Roesch, Alessandra Salgado and Judit Hecke at IRENA run through the technologies used to extract energy from tides and waves, the potential near-term … [Read more...]
