Whereas blue hydrogen from methane produces CO2, the by-product of turquoise hydrogen is pure carbon. The obvious advantage is you can make your hydrogen without the need for expensive new infrastructure to transport and store any CO2. Turquoise hydrogen is only at the start-up phase, so Schalk Cloete summarises his co-authored paper that looks at various scenarios to estimate the cost of producing the hydrogen (using molten salt pyrolysis) and, … [Read more...]
Case study Italy: Optimising emissions cuts means we’ll need “grey” and “blue” Hydrogen too
Europe is committing to hydrogen. The ideal is “green” hydrogen, produced from renewable energy alone. Carlo Stagnaro at Istituto Bruno Leoni analyses emissions and costs in Italy to make the case for policy-makers to consider including “grey” and “blue” hydrogen in their strategies too. Because grids are far from green today, a new wind and solar plant will reduce more emissions by feeding the grid than by making hydrogen. “Grey” hydrogen, … [Read more...]
