[Stoves] "Advancing Heating Services Beyond the Last Mile : Central Asia Pilot Experience with High-Efficiency, Low-Emissions Heating Technologies", ESMAP, World Bank 2019

[Crispin Pemberton-Pigott]

Dear Friends of Advanced Stoves

There is a new technical paper in the World Bank's Open Knowledge Repository:

"World Bank Group. 2019. Advancing Heating Services Beyond the Last Mile : Central Asia Pilot Experience with High-Efficiency, Low-Emissions Heating Technologies. ESMAP Paper; World Bank, Washington, DC. (c) World Bank.

This paper on HELE stoves is downloadable from the following webpage:
https://openknowledge.worldbank.org/handle/10986/31282 or http://hdl.handle.net/10986/31282

The document provides a detailed description of how one of the cooking and heating stove technologies used in the Kyrgyzstan Winter Heating Pilot was developed.  It is a comprehensive discussion of the social and technical factors that contributed to the success of this Pilot, producing significant impacts on health, income and comfort of people living "beyond the last mile". A link is provided to the full set of drawings and some photos archived in the ESMAP<https://collaboration.worldbank.org/content/sites/collaboration-for-development/en/groups/clean-cooking-and-heating-solutions.html> Library<https://collaboration.worldbank.org/content/sites/collaboration-for-development/en/groups/clean-cooking-and-heating-solutions/files.html>.

The point of saying "beyond the last mile" is that whatever are the current plans to extend modern heating and cooking services, there are a large number of people who will not be reached. This group of 500m people "beyond" are, now and in the medium term, dependent on burning solid fuels (biomass, dung and coal).  The question addressed is: What can we do for this group of low income, deeply rural and hardly accessible families which suffer all the negative consequences of chronic cold, poor combustion, indoor leakage of smoke, inconvenient drudgery and a dire lack of access to modern energy?  How can we bring modern science and engineering to these spatially and culturally diverse groups?

The article proposes a comprehensive approach and describes how this was done in highland, rural areas of Kyrgyzstan. It covers in some detail how the KG4.3 crossdraft stove was developed over 9 years and the scientific cooperation between groups in several countries that led to the development of this HELE technology.

This document can be used to inform policy in multiple ways. If we are to eventually bring modern energy services to everyone, which will take time, there are highly beneficial interventions which can be made a low cost per person, even in poorly served regions using carefully crafted technology transfers. Apart from all the social and health benefits, the project also makes positive impacts on everything from local employment, the social status of women, emissions of CO2, Black Carbon and PM2.5.

Two further papers reporting the health benefits of the project have been submitted by the Dutch International Primary Care Respiratory Group<https://www.theipcrg.org/> to the WHO Bulletin and npjPCRM<https://www.pcrs-uk.org/npj_articles> (Primary Care Respiratory Medicine) which conducted a Fresh Air<https://www.theipcrg.org/display/DoResearch/FRESH+AIR+The+Kyrgyz+Republic>-sponsored study of the impacts of the stove and low pressure boiler replacements.

Please circulate the links given above to anyone who you think is interested in these topics.  Stove designers will find a good deal of technical information about construction and principles of combustor operation, as well as guidance on how to interact with the communities in which it is intended to provide such modern heating and cooking services.  This crossdraft technology has already been replicated in China, Kyrgyzstan, Mongolia, Russia, Poland, South Africa and Tajikistan. A few photos are provided.

Forthcoming: Complete details on construction of three versions of the technology will be included in the final report from the World Bank-funded UB-CAP Project in Ulaanbaatar, Contract C-5039-MN/KLTA-01.
