Modelling green Ammonia and Methanol in 2050. It will be expensive

September 9, 2022 by Schalk Cloete

Schalk Cloete starts by explaining that it is unrealistic to expect clean electrification to carry the main burden of energy supply. Even a fast roll out will be constrained by a range of infrastructure and cost limitations. Hence our continued dependence on fuels, with their high energy density and ease of transport. Those fuels will have to be made clean, so he summarises his co-authored papers that model the cost of green and blue ammonia and … [Read more...]

Clean Turquoise Hydrogen: a pathway to commercial readiness

July 22, 2022 by Schalk Cloete

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...]

A role for Coal? Low-cost, negative emissions Blue Hydrogen from “MAWGS” Coal/Biomass co-gasification

July 15, 2022 by Schalk Cloete

Schalk Cloete summarises his co-authored study that explains how to make hydrogen at unbeatably low prices from coal/biomass co-gasification. Though the “blue” hydrogen process creates CO2, the self-contained plant using a membrane-assisted water-gas shift (MAWGS) reactor means 100% is captured easily. Better still, the use of biomass means the plant achieves negative emissions. The overall efficiency of the process is a very impressive 69%. The … [Read more...]

Hydrogen at COP26: committing to scale-up and creating demand

November 29, 2021 by Cato Koole and Thomas Koch Blank

At COP26 the voice of hydrogen staked its claim to meeting its targets and its contribution to making the 1.5°C scenario a realistic ambition. Cato Koole and Thomas Koch Blank at Rocky Mountain Institute explain that hydrogen supply should not be the problem. The combination of deployed and announced projects already places the world close to the green hydrogen production capacity needed as outlined in the IEA’s "Net Zero by 2050" roadmap. The … [Read more...]

Case study Italy: Optimising emissions cuts means we’ll need “grey” and “blue” Hydrogen too

June 1, 2021 by Carlo Stagnaro

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...]

The Netherlands: a Blue Hydrogen economy now will ease a transition to Green

April 26, 2021 by Barthold Schroot

Barthold Schroot at EBN makes the case for blue hydrogen for the Netherlands now, to minimise emissions and make life easier for green hydrogen later. The country is a big consumer of natural gas that, realistically, cannot be quickly replaced with renewables. So what’s the best alternative to burning that gas and can be introduced the soonest? Green hydrogen production (emissions-free) will take time to reach scale as it needs to piggy-back off … [Read more...]
