The ability to transport hydrogen in bulk will mean clean energy can be taken where it’s needed, as easily as fossil fuels are today. But there is a cost involved in converting the hydrogen into something easy to transport (and un-converting it at the destination). Herib Blanco at IRENA summarises the findings of their paper that looks at those costs: a better understanding will enable us to choose the right pathways today fit for the next 30 … [Read more...]
Will this be the decade of Carbon Capture or another false start?
Ten years ago there was a major drive to get carbon capture off the ground. But only 30% of the earmarked $8.5bn worldwide was ever spent. Spending timescales were too short, deadlines were missed, projects were too focussed and too complex, and long-term liability was poorly understood and managed. This time it can be different, says Samantha McCulloch at the IEA who compares that faltering history with the plans now being put in place. New … [Read more...]
Modelling Hydrogen’s role in high penetration Wind + Solar grids
A hydrogen ramp-up is going to be expensive and asset-heavy. So, a whole-system analysis is needed to ensure its deployment is done cost-effectively today and meets long term goals. This is what all nations committing to hydrogen are struggling with. Kelley Travers at MIT describes their modelling, in collaboration with Shell, that looks at the optimisation of hydrogen deployment in grids where variable renewables (VREs) like wind and solar are … [Read more...]
How to share the cost of an EU-wide Hydrogen network
The EU’s ambition is to make green hydrogen available throughout the region, and ramp up the transportation infrastructure as fast as possible to deliver it at a competitive price. But there are big disagreements between stakeholders over how and who should pay, explains Walter Boltz. The simplest solutions like focussing on hydrogen clusters will only deliver it to nearby customers. If only the customers pay it will make the hydrogen very … [Read more...]
