Grid-eCook price parity in Africa

africa gridKittner et al. (2017) suggests that the main eCook component cost, battery storage, is following Leach and Oduros’ optimistic scenario, with faster than expected learning curves suggesting that 200USD/kWh could be a reality by 2019.  Similarly, initial prototyping has shown that efficiency gains in the cooking processes can even exceed Leach and Oduro’s optimistic scenario for energy demand.  We created a set of choropleths for Africa, in the hope they become a decision tool for policy actors.  The figure illustrates the LCoE[i] thresholds eCook will have to cross to be at price parity with the alternative fuels.

[i] Levelised Cost of Energy

Swappable batteries

There have been a few half hearted tests on the idea of swappable batteries for electric vehicles.  The idea that you pull into a fuel station and in 90 seconds swap in a fully charged battery has enormous potential on paper.  Imagine – while the UK is running out high speed charging points and strengthening infrastructure, how will most developing economies which are currently struggling with domestic electricity access ever accommodate EVs?  One answer is swappable batteries – and that has relevance to eCook.

Learning from the UK? Pt 3

  • Much of the savings at a household level come from pre-prepared food, and the overall energy to prepare the food has likely remained the same.

However thirdly, in the UK  “the huge expansion in ‘ready meals’ and takeaways is probably a bigger factor in the decline in cooking energy, and it is questionable whether these lifestyle changes have saved energy overall.Read more…
