eCook Zambia Kick Off Meeting Minutes

Belated but worth a read on the basic ideas.
The eCook Zambia Kick off Workshop brought together key stakeholders from the solar lighting, clean cookstoves and utility sectors to discuss the proposition of battery – supported cooking. The Centre for Energy, Environment and Engineering Zambia (CEEEZ) in partnership with a UK research consortium (Gamos Ltd., University of Surrey and Loughborough University), are collaborating on an initial exploratory study to investigate the opportunity for this potentially transformative technology, which is
designed to extend access to electricity access and clean cooking facilities to poorer households (

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.

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.
