ETHOS 2015 Presentation: Advances in TLUD and Other Micro-gasifier Stoves During 2014
Clean Stove Initiative Results for Prime Square Regular Fuelwood Efficiency: 1 star CO emissions: 3 stars PM emissions: 3 stars
Prime Cookstoves AS is a company established by Differ AS and Dr. M. Nurhuda in 2013 to internationalize and scale up sales of Nurhuda’s TLUD gasifier stoves (UB-03), which utilizes pre-heating, counter-flow burning mechanism and co-firing. Prime Cookstoves manufactures its stoves in Indonesia and exports these globally.
Prime Square Regular Fuelwood Prime Square Regular Granular (pellets) Large version of the square design to be released in 2015 Cylindrical version to be phased out
Prime Square Regular Fuelwood: 4,200 units Prime Square Regular Granular (pellets): 2,200 units Other models: 500 units Accumulated sales (2013-2014): > 8,000Approximately 70% of these stoves have already been sold on to end-users by Prime’s distribution partners on commercial terms.
Markets Indonesia, Zambia, South Africa, Senegal, other countries in SEA and Africa Samples sold to more than 20 different countries worldwide Ongoing pilot projects in new potential markets.
Outsourcing at high precision manufacturing facilities expected operational from Q2 2015
Growth Prime seeks strong distribution partners in key markets in Asia and Africa for long term collaboration.
The lack of suitable loan facilities for cash-constrained distribution partners is a major barrier for scaling up operations. Distributors commonly sell the cookstoves to end-users utilizing various financing schemes (instalments etc.). As the total financial outlay will only be collected several months later, distributors are unable to purchase new cookstoves on a regular basis and risk running out. Differ and Prime are crafting solutions to deal with distributors' initial cashflow needs through financing as well as other ways to gradually scale up deliveries.
Land transportation costs are a main barrier for exporting to distributors in land-locked countries in Africa - can more than triple the per unit shipping cost
Prime has supported long-term distribution partners by finding flexible solutions for minimizing shipping costs such as optimizing container usage. In 2015, Prime will explore flatpacking and local assembly, aiming to increase the quantity in a 20’’ container from 1,000 to 2,000 units.
The Prime Square TLUD has successfully met the three criteria (fuel efficiency, low emissions of CO and PM) of the Indonesian Clean Stove Initiative (CSI) and is elegible for an Indonesian government subsidy in the two selected pilot areas.
The granular stove, which is mainly being used for woodpellets or rice husk pellets, has been increasingly popular in 2014, due to ease of use (no chopping of wood needed), smokeless burn, long cooking time, as well as it being suitable for more urban areas where end-users are accustomed to paying for the energy needs. The fuelwood version is mainly sold in rural areas.
Products End-users are more positive towards Prime Square Biomass Cookstove than the cylindrical design 2015: Cylindrical design will be phased out and Prime will release the square stove in a large version (for
Low Emission Enterprises (LEE) ProjectPT. Ditana Energy Solutions -- Indonesia
In 2013, Differ received co-funding from USAID and the Walton Family Foundation under Conservation International's Sustainable Landscape Partnership (SLP) program in North Sumatera, Indonesia, to develop and establish PT. Ditana Energy Solutions (Ditana), a financially sustainable distribution company for clean and efficient Prime cookstoves in North-Sumatra, Indonesia. Differ is distributing and selling the fuel-efficient cookstoves under the Low Emission Enterprises Project (LEE) on SLP in collaboration with Kopernik, an Indonesian NGO.
Stoves are not subsidised – Ditana will be a commercial enterprise
Project started on 1 November 2013
1,750 stoves sold to date 16 full-time staff More than 100 local retailers have signed up: individual agents and group agents
(cooperatives, formal/informal associations) Stove models sold: Prime Square Regular Fuelwood (95%) and Prime Cylindrical Large
About LEE Project
Local agents purchase from LEE/Ditana, then resell the stoves with a margin LEE/Ditana provides a recommended retail price but the market determines the end-user price LEE/Ditana recruits agents, provides technical training and marketing support, logistics
LEE Ditana Distribution System
Individual agents: Upfront cash or 3-months’ installment system Group agents: Upfront cash or 6-month installment system with consignment Payment default rate on installments to date: < 1%
Fuelwood savings: 57% Monetary savings per household per week: > USD 2.5 Payback time for the Prime cookstove: < 3 months Time saving for cooking : 30 min/day Time saved on fuelwood collection: 8 hrs/household per week
Preliminary Impact Assessment results (Dec 2014)
Installment payment system needed to mirror financing offered by agents to the end-user to ensure reordering and remove financing bottleneck
Strict procedures for payment collection are extremely time consuming but highly necessary
Ditana seeks equity, debt or grant funding for expanding operations to other parts of Indonesia beyond 2015Financial needs
Home Energy Ltd / Miombo AS --Zambia• In the pilot project, 3
Peko Pe cookstove models are offered. – One in stainless steel
– One in mild steel, painted black (USD 15)
– One in mild steel unpainted
With 6 weeks of selling some 60 stoves are sold. The only marketing tool is a sign at the sales outlet. At the time, all marketing is by «word of mouth». This to test the effect of this marketing tool. Marketing will be scaled up as the pilot progress.
This appears to be the same manufacturer of the Reed Woodgas Campstove that is no longer available outside of India. Attempts to communicate have not yet been successful. Price information is not available. Website: www.ecochula.co.in

Biomass Cooking Stoves Mailman List (“Stoves Listserv”):lists.bioenergylists.org/mailman/listinfo/stoves_lists.bioenergylists.org
This web page has links to the Stoves Archive and the Improved Biomass Cooking Stoves website, as well as a subscription form for visitors who want to become list members.
• Primarily a news and resource-sharing venue. • Not a blog or discussion venue, although visitor
comments are welcome.• Dr TLUD’s discussion venue is the Stoves Listserv (see
previous slide).• The Resources page (drtlud.com/resources) is, for
many, the centerpiece of the website. Here, visitors find a searchable and ever-growing collection of online resources about TLUDs and TLUD Technology (PDF paper publications, videos, slideshows, spreadsheets, website URLs, etc).
• The resource collection is continually updated with new content – this includes all publications of the former Biomass Energy Foundation (BEF).
Sharing TLUD Resources
• In 2013 and 2014, the Dr TLUD website generally had 150-300 visitors per day from every major country in the world.
• As we continue to update and grow the website in 2015 and beyond, we will host and/or link to many, many more TLUD-related resources. Our goal is to be the first-choice destination for finding TLUD-related content that is:a) Freely available, centrally-organized, easily-searched, andb) Open for content creators who want to share their papers, videos,
slideshows, images, spreadsheets, drawings, and external links to similar resources where they exist elsewhere on the web.
• We invite visitors to send an email to [email protected] to submit new or existing TLUD-related content for inclusion on the website as a new resource. Submissions of files (PDF, PPTX, MP4, etc) should also include the author’s or publisher’s permission to upload and share. For items already uploaded and available elsewhere on the web, please send us a link. We also welcome links to relevant blog posts, articles, informative websites, and the like.
Developer CreditAll preparation, conversion, and tagging (indexing) of resources is handled by James S. Schoner, the Dr TLUD website administrator and developer. James also administers the Dr TLUD YouTube and Slideshare accounts for videos and slideshows (respectively).
James lives in Phoenix, Arizona and is interested in doing additional technical work in the Stove and Biocharcommunities. Anyone with online technical needs is invited to contact him by email: [email protected] information can be found on his business website: bitmaxim.com
Stove Camps and Research
• TLUD technology featured at Stove Camp at Aprovecho in July 2014.
• Stove Camp in Kenya by Christa Roth and Elisha …..
Making Charcoal with TLUD Stoves
• This is certainly possible.
• This continues to be a topic of discussion because of the differences in perception of the value of biochar for soil amendment.
• Is the energy value of char allowed to offset the calculations of ENERGY efficiency and also of FUEL efficiency?
