Christa Roth has updated the GIZ HERA Micro-gasification Manual
https://energypedia.info/wiki/File:Micro_Gasification_2.0_Cooking_with_g...

It is extensively revised, and features good -clear descriptions of essential cooking stove topics, e.g. choosing appropriate fuels, cooking stoves and technologies.

She highlights all of the major micro-gasifier cooking stoves, and includes a new section on biochar, with good, clear graphics and descriptions for how to use biochar.

An essential reference for everyone's cooking stove library, and this is all work supported by the German people through GiZ, we appreciate their support of Christa's amazing work.

Christa Roth's excellent report
Micro-gasification: Cooking with gas from dry biomass

has a new location:
https://energypedia.info/wiki/File:Micro_Gasification_Cooking_with_gas_f...

Her comprehensive survey of micro-gasification technology has great technical information and is well worth the read.

thanks to GiZ (the German people) for making it available to all of us.

I am good, pretty busy with the work at Prakti and other stuff, there is a lot of good projects and ideas coming up at Prakti, we are living enthusiastic times!

I saw the GIZ 'Pulumde' when I was in Benin, interesting design, looking sturdy like a Roumde and with a grate like a Pulumusa. I remember secondary air was exiting above the charcoal pile from a metal tube attached to the grate, but it wasn't working well, and I think it was taken out later on.

The improved malgache I made wasn't really convincing in terms of performances. Something wrong with the air flow, I guess. Needed a lot of design work, way more than I could do with my small knowledge. Perhaps a two-stage door like you are proposing would improve the performances, yes.

I think GIZ with the Pulumde and you with the improved malgache are on to something.

A few pictures of the improved malgache are attached.

Now my main concern was to make a heat-resistant combustion chamber/cone/grate? Either good and thick metal, either a ceramic one like the POCA you showed me.

Cheers,

Xavier Brandao

To the members of the list who don't know Energypedia yet: it is an online resource created as a Wiki by GIZ . After some years of development as company-interal resource, it was opened to the public energy community late last year. No registration needed to read.

Dear all, find below the links to new publications by GIZ HERA poverty-oriented basic energy services, among them the manual on Micro-gasification: Cooking with gas from biomass. For queries please refer to the respective authors or Michael Blunck from HERA.

Micro-gasification: Cooking with gas from biomass

- new link : https://energypedia.info/wiki/File:Micro_Gasification_Cooking_with_gas_f...

Micro-gasifiers: much more than „just another improved cook stove”. In this new HERA handbook, Christa Roth provides an introduction to the concept and the application of wood-gas burning technologies for cooking.

Modern Energy Services for Modern Agriculture. A Review for Smallholder Farming in Developing Countries.
http://www.gtz.de/de/dokumente/giz2011-en-energy-services-for-modern-agr...
This publication provides an overview on energy inputs required in different steps of the agricultural production chain, such as production, post-harvest and storage, processing, and commercialization.

Small-scale Electricity Generation from Biomass – Part III: Vegetable Oil
http://www.gtz.de/de/dokumente/giz2011-en-small-scale-electricity-genera...
In the third and final part of HERA’s paper series on power generation from biomass, GIZ and non-GIZ experience with electricity production from vegetable oils is compiled. While from a technology point-of-view, plant oils constitute a very viable option for off-grid power generation in developing countries, their sustainable application in daily operation for rural electrification projects still remains rare. The paper identifies remaining bottlenecks and provides recommendations for future electrification projects based on plant oil.

Carbon Markets for Improved Cooking Stoves – Revised Edition: January 2011
http://www.gtz.de/de/dokumente/giz2011-en-carbon-markets-for-improved-st...
After receiving a lot of positive feedback for the 2010 edition of the carbon market guidebook for cooking stove projects, HERA has come up with a major revision for 2011. Besides a large number of minor corrections and updates, a new chapter on “Implementing a Carbon-funded Cooking Stove Project” with information on how to practically design a carbon-funded stove project has been added. The chapter includes information on stakeholders’ roles and responsibilities, the CDM-PoA approach, recommendations on the use of carbon revenues as well as an overview on expected costs and revenues from a stove project on the carbon market.

The GTZ project “Poverty-oriented Basic Energy Services (HERA)” has launched a comprehensive guide on carbon markets for improved cooking stove projects. The guide offers an overview of the various steps in the project cycle of CDM and Gold Standard projects, describes existing methodologies, and addresses the most critical issues in project development.

The guide is updated on a regular basis and has recently been supplemented with the latest changes in the CDM methodology AMS-II.G. HERA is closely following the ongoing discussions for a second revision of the methodology which might take place in April 2010.

“Carbon Markets for Improved Cooking Stoves – A GTZ Guide for Project Operators” can be downloaded from
http://www.gtz.de/en/themen/umwelt-infrastruktur/energie/20674.htm

Your feedback and project experiences are highly welcome to keep the guidebook up to date!

Best regards,
Michael Blunck
