Electricity has well known limitations, mainly for bulk and long-range transport, industrial processes requiring high temperature heat, and the chemicals industry. To entirely replace fossil fuels we need hydrogen, say Frank Wouters and Prof. Dr. Ad van Wijk. It has an energy density comparable to hydrocarbons. There's more: Europe’s electric grid can’t cope with 100% electrification, yet hydrogen would use the existing gas pipe networks. The … [Read more...]
We need to trace the real fossil fuel users, not just the “end consumers”
Climate-consciousness is rising among ordinary citizens. But most fossil fuels are consumed by large technological systems (electricity networks, urban transport systems, built environments, industrial and agricultural systems), not by individuals. Simon Pirani says we need to trace that consumption to its true source, and thereby put the pressure directly on them to transition. It’s not simple: even the IEA admits it loses track of who is … [Read more...]
The rapid growth of solar integration into grids: learn from Germany
With the rapid electrification of Europe’s energy system, the network operators are facing a challenge. The integration of more and varied electricity generation is putting a strain on the growth of grids. Erik Rakhou and Chris Collins contrast the struggles the Netherlands is experiencing with the smoother ride navigated by Germany where in the 12 years to 2015 solar PV capacity rose around 100-fold from 0.44 GW to 39.7 GW. Greater investment, … [Read more...]
