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...]
Price volatility and greenwashing: do Gas and LNG make economic or climate sense?
While governments urgently rethink their gas policies, Christina Ng and Sam Reynolds at IEEFA summarise the evidence against the claim that gas and LNG can be green and have a sound economic future. Firstly, most measurements of emissions do not include the full life-cycle of production. For LNG that includes extraction, transport, liquefaction, and re-gasification. They point at studies that say it can be almost as much as the emissions produced … [Read more...]
The Green Hydrogen disruption: what nations, firms and investors are doing to reshape global energy
Everyone knows the new hydrogen economy has huge up front capital costs to make the green H2 (called GH2), the logistical challenges of delivering it where itâs needed, and creating the customer base to consume it. But Tim Buckley at IEEFA believes the policy support is already shaping up to make GH2 a successful disruptor of the global energy system. He runs through the nations, companies and investors at the beginning of the learning curve that … [Read more...]
Hydrogen at COP26: committing to scale-up and creating demand
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 IEAâs "Net Zero by 2050" roadmap. The … [Read more...]
Green Finance standards: the EU Taxonomy and Chinaâs âCatalogueâ
The EU Taxonomy was published in June 2020. It is the first official document to define and classify what is a truly sustainable economic activity in Europe. Six months later Chinaâs regulators published their own version, a new edition of the China Green Bond Endorsed Project Catalogue (the Catalogue). Both documents will act as important standards for green finance institutions and investors in Europe and China. They are intended to improve … [Read more...]
Case study Italy: Optimising emissions cuts means weâll need âgreyâ and âblueâ Hydrogen too
Europe is committing to hydrogen. The ideal is âgreenâ 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 âgreyâ and âblueâ 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. âGreyâ hydrogen, … [Read more...]
The Netherlands: a Blue Hydrogen economy now will ease a transition to Green
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 whatâs 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...]
