A new study concludes that heating from 100% green-hydrogen would be up to three times more expensive than one based on 100% electrification of buildings with heat pumps. Josh Gabbatiss at Carbon Brief summarises the findings, who says it’s yet more evidence to push back against the voices of politicians and fossil-fuel companies wanting to see hydrogen in the household and buildings heating mix (for example, the UK is planning a “hydrogen … [Read more...]
Virtual Power Plants: efficiently networked households won’t need new expensive generation
Virtual Power Plants (VPPs) are the next new innovation that can change the landscape of the global energy transition in our favour, cheaply and fast, explain Liza Martin and Kevin Brehm at RMI. Essentially, they link and aggregate hundreds of thousands of households and businesses to manage their electrical devices. Their thermostats, EVs, appliances, batteries, and rooftop solar arrays are coordinated to ensure loads, charging and discharging … [Read more...]
Will turning down Europe’s thermostats ease the Gas supply crisis?
To counter the extremely high gas prices caused by the Russia-Ukraine crisis the IEA has proposed turning thermostats down in households to use less gas. The IEA estimated lowering the heating by just 1°C would reduce gas demand by around 10 bn cubic metres a year, or 7% of Europe’s annual imports from Russia. Aurore Julien at the University of East London looks at quantifiable past attempts around the world to get citizens to cut their energy … [Read more...]
