Haiti

Una reciente evaluación realizada por los refugiados de la Mujer de la Comisión en Haití constató que el precio del carbón ha aumentado en un 40% (CMR y el PMA 2010). Cómo ayudar a las poblaciones sujetas a desarrollar la capacidad de producción de biocombustibles líquidos puede ofrecer una importante solución a la pobreza energética en las comunidades desplazadas de Haití y contribuir a su desarrollo a largo plazo de la autosuficiencia energética.

Proyecto Gaia ha estado trabajando en Haití para promover el etanol y la Estufa CleanCook - una estufa a base de alcohol - como alternativa a las estufas que queman biomasa sólida (es decir, madera, carbón vegetal y briquetas.) El etanol es tan limpia como gas licuado de petróleo, más barata que el carbón, más seguro que el queroseno y tiene más potencial que las briquetas de basura. En África, el Proyecto Gaia ha acumulado más de 2 millones de días de cocinar con la estufa CleanCook sin un solo accidente de cierta importancia.

La pregunta más común que aparezcan durante nuestras conversaciones con los responsables políticos y los empresarios sociales es: ** "¿El suministro de etanol, sea sostenible? Y ¿dónde estaría la oferta provienen de donaciones después tocaban a su fin? "**

Esta es la pregunta clave de la sostenibilidad y la razón de por qué estamos tan interesados en Haití. No sólo fue Haití una vez al líder productor de azúcar y una destilería de etanol de bebidas para la exportación, así como el mercado local, pero también Haití existe en las rutas comerciales durante el cual miles de millones de litros de etanol cada año el flujo de camino a un mercado de combustibles en el los Estados Unidos. Este etanol, sobre todo de Brasil, generalmente el precio más competitivo en el mercado de materias primas, proporcionará una fuente de combustible para Haití-más barato que el petróleo-como Haití acumula su propia producción local (Etiopía Petróleo de datos empresariales). De hecho, el Gobierno brasileño se ha comprometido a donar más de 100.000 litros y un litros otros 400.000 en los próximos dos años.

Improved Charcoal Stove

Improving the Charcoal Stove for Haiti, Stove Camp 2010 (see the Stove Camp Summary for challenge details)

Main points mentioned at the end of the Stove Camp Workshop

  1. We need a high turn down ratio.

    To bring water and foods fast to the boil, we need high power in the heat-up phase.
    However, thereafter we commonly need low power for simmering. The stove
    therefore needs to offer the opportunity to turn down the power output drastically.
    Options:

    1. Regulation of primary air supply (e.g. closing door)
    2. The gap between pot and charcoal is increasing over cooking time (shape of char container provides more depth = increased gap to the char)
    3. c) The amount of char available at the end of cooking is reducing (conical shape of char container = less char over time available)
  2. We need to reduce heat losses to the bottom and to the side of the stove.

    A char container radiates heat to all sides – not just to the pot. To reduce the amount
    of char used, it is important to reduce the heat losses to the other directions.
    Options:

    1. Bottom of stove: rebounding plate (with holes) in between primary air supply
    2. intake and charcoal container. Thus primary air is channeled through the
    3. heated rebounding plate, taking some heat back into the char container.
    4. Side of the stove: double wall with air in between for insulation.
  3. We need to maximize heat harvest from a given amount of charcoal.

    Charcoal burning is mainly influenced by the amount of air available in the char
    container.
    Options:

    1. A vertical spacer in the center of the charcoal container (Lanny Henson’s pig tail”) seemed to increase the availability of air for charcoal combustion.
    2. Additional draft (e.g. forced air) may increase heat generation per time unit. However, this may also increase CO emissions and reduce efficiency of char use.
    3. Secondary air to burn off the CO in a gap between the charcoal and the pot may provide additional heat. However, for this to be beneficial it may not impact on the surface area available for direct radiation from the charcoal to the pot and should not cool down the air in the gap (well preheated secondary air).
  4. We need to maximise heat transfer to the pot.

    Generating as much heat as possible out of a given amount of charcoal is one step.
    But another important step is to make sure that most of this heat actually is
    transferred into the cooking pot.
    Options:

    1. “Sunken pot” concept seems to provide best results in terms of heat transfer (Henson stove). Unfortunately, in real life this might not be possible in many work environments.
    2. Best heat transfer is NOT achieved if the pot rests on the char. Optimum is about 1inch away from the char, not closer than that. For Simmer, this could increase to 2-3 inches.
    3. A skirt is highly important to shield the gap area between the pot and the char against the influence of wind. The gap between pot and skirt should bedetermined.

Christa’s Summary of the stove camp

Observation and necessary action Derived Design Principles
Charcoal radiates heat to all
sides: as much can radiate
towards the bottom of the stoves
as can radiate upwards towards
the pot.

Action:
Avoid loss of radiating and
conducting heat from charcoal
that is not directed towards the
pot.

  • Add space between the charcoal grate and other stove parts: Lift the charcoal grate slightly off the bottom of the stove and increase the space to the sides of the stove.
  • Limit the places where the hot grate can conduct heat to other stove parts.
  • Add a deflector plate between charcoal chamber and the stove bottom to radiate heat back upwards.
  • Insulate the stove bottom to prevent heat loss through the bottom.
  • Insulate sides of the stove.
  • Regain heat through air circulation (air cooling of stove) by passing air through heated stove parts thus preheating air entering the combustion system. This can be by passing primary air through the deflector plate below the grate and/or secondary air through a gap between double side walls of the stove.
Charcoal combusts in function of the available oxygen. Thus heat generation is a function of
air supply to the charcoal grate.

Action: get the right amount of air to the charcoal grate. To little will choke the combustion, too much will cool the flue gases.

If power of the stove is too low, increase air supply by

  • making more holes in the grate.
  • adding a ‘Henson pig-tail’ vertical air-pass through the charcoal bed.

Do not pile the charcoal up too high, as this will restrict air flow through the charcoal bed (this is influenced as well by the shape and particle size of the charcoal chunks).

The combustion of charcoal goes from oxidizing C to CO, then in
a subsequent step from CO to CO2.

CO is a toxic gas and has still considerable energy value. Ensuring a complete combustion
will increase energy output and reduce toxic emissions.
Action: avoid CO emissions.

Charcoal radiates heat but there is also considerable convection of hot flue gases.
Action:
Optimize transfer of created heat into the pot.
Avoid obstructions between the radiating charcoal bed and the bottom of the pot (increase
the view factor of the charcoal seeing the pot).

Patrick Bringardner, Project Gaia, August, 2010

A recent assessment conducted by the Women’s Refugee Commission in Haiti found that the price of charcoal has risen by 40% (WRC and WFP 2010). Helping subject populations to develop the capacity to produce liquid biofuels may offer one important solution to energy poverty in Haiti’s displaced communities and contribute to its long term development of energy self-sufficiency.

Clean Cook StoveClean Cook Stove

Project Gaia has been working in Haiti to promote ethanol and the CleanCook Stove - an alcohol based stove - as an alternative to stoves that burn solid biomass (i.e. wood, charcoal, and briquettes.) Ethanol is as clean as LPG, cheaper than charcoal, safer than kerosene and has greater potential than trash briquettes. In Africa, Project Gaia has accumulated over 2 million days of cooking with the CleanCook Stove without a single accident of any significance.

The most common question which arises during our discussions with policy makers and social entrepreneurs is:** “Would the supply of ethanol be sustainable? And where would the supply come from after donations were at an end?” **

This is the key sustainability question and the reason why we are so interested in Haiti. Not only was Haiti once a leading sugar producer and a distiller of beverage ethanol for export as well as the local market, but also Haiti exists on trade routes over which billions of liters of ethanol flow each year on their way to a fuel market in the United States. This ethanol, mostly from Brazil, generally the most competitively priced in the commodity market, will provide a source of fuel for Haiti—cheaper than kerosene—as Haiti builds up its own local production (Ethiopian Petroleum Enterprise Data). In fact, the Brazilian Government has pledged to donate over 100,000 liters and an additional 400,000 liters over the next two years.

Haiti was once a powerful agricultural economy, producing for its own needs. In 1983 Haiti harvested 70,000 hectares of sugarcane. Today it harvests less than 17,000 hectares (Figure 1: Decline in Sugar Cane Production (UN Data World Statistics Pocketbook)). Haiti’s dependence on export markets has increased its vulnerability through its reliance on basic sustenance items it once produced locally. Today it supplements most of its own food staples with imports – a precarious equilibrium. Other than charcoal, most other fuels are imported.

In regards to domestic ethanol production, Haitians are no strangers to the distillation of alcohol. Thousands of small mills and distilleries make beverage-grade ethanol in Haiti. In Léogâne alone, over 200 small distilleries were in operation before the earthquake (ESMAP 2007). Many of the existing distilleries in Haiti, those shut down or still in operation, could be repaired and refurbished to produce fuel grade ethanol. Project Gaia has been in contact with an operating distillery in the vicinity of Léogâne that could upgrade to produce hydrous ethanol fuel and put this fuel into the market in a matter of months.

Many opportunities exist for small scale distilleries. In Haiti, some small ethanol enterprises are already active thus presenting the perfect opportunity for value chain development through the support of SMEs (small and medium enterprises). The number of sugarcane transformation workshops throughout the country is an estimated 5,612 (ESMAP 2007)

Haitians rightly believe that Haiti’s way back from dependency is through agriculture and a renewed attention to domestic needs and markets. Therefore, by developing ethanol as a household fuel, it will profoundly benefit Haiti because Haitians can produce biofuels from their own agricultural crops. Moreover, Haitian families will finally have access to cooking fuel that is safe, clean, affordable and sustainable. A way back to economic - and human - health for Haiti is to produce ethanol for its domestic energy market.

Nat Mulcahy and the World Stove Haiti project was nicely profiled on the web site The Charcoal Project. Read the full article A Man, a Stove, a Mission

From the Charcoal Project article:
"Mulcahy is the founder of WorldStove, a small Italy and U.S.-based company that manufactures a range of energy efficient, biomass-burning cookstoves. The company operates two business lines. One sells pricey cookstoves and barbeque grills for the outdoor/camping crowd in industrialized societies. The other line of stoves, the research of which is funded by the former, helps bring energy efficient cookstoves and locally owned businesses that produce them, to the oceans of energy poor people around the world who don’t have access to modern fuels like LPG and electricity.

"Mulcahy has recently returned from Haiti where he spent two months setting the foundations for a sustained long-term plan to alleviate the country’s heavy dependence on the inefficient combustion of the wood and charcoal. President Bill Clinton, the UN Special Envoy to Haiti, highlighted WorldStove’s remarkable and quick work in Haiti in a recent Earth Day address."

The World Stove has also been profiled (by Kelpie Wilson) on the Huffington Post, read WorldStove: Transforming Haiti and the World

Rochester Institute of Technology: Develop Thermoeletric Stove Test Methods and Capability
Robert Stevens, Brain Thorn

Project Summary

According to the World Heath Organization more than three billion people depend on biomass fuels (wood, dung, or agricultural residues) primarily for cooking. The practice of cooking with biomass has decimated many ecosystems and requires an enormous amount of human effort to gather. In addition, there is considerable evidence that exposure to biomass smoke increases the risk of common and serious diseases in both children and adults. According to the WHO studies, indoor smoke from solid fuels causes an estimated 1.6 million deaths annually.

To minimize these harmful effects associated with cooking more efficient cook stoves have been proposed. These new stoves are significantly more biomass fuel efficient and thus reduce deforestation rates. These enhanced stoves also reduce indoor air pollution, thereby reducing deaths and illnesses due to biomass cooking.

RIT is working with an NGO partner in Haiti, H.O.P.E., and funded by an EPA Energy Research Grant to develop an enhanced stove. Concurrent with this team's work, a separate group will develop stove concept, design it, and create prototypes. This project is to develop a series of stove measurement and characterization methods and reduce them to practice. The mission of this project team is to define test methods relevant to the Haitian customer needs and, in addition, that quantifies the stove's fuel efficiency, cooking performance, and hazardous emissions in engineering terms.

Improved Cookstoves for Haiti

Nathaniel Mulcahy, March 2010

Over the past weeks several NGOs and individuals have written to ask how it is that we determined how much a family spends each day on charcoal. This is the initial survey we did for IOM over a month ago (pdf). We have since continued each week to do updates but the numbers are unchanging. The three camps I have chosen to include in the excel are good examples of the variation. One is a semi permanent camp that, in part, was there prior to the quake, one is an organized camp that was established through collaboration between the local government and various local and international NGOs, and the third is a spontaneous camp that sprang up post quake in the hopes that aid would arrive. On a happy note, since we did this original survey I am happy to report that the spontaneous camp has received showers and sanitation facilities and a great number of tarps and tents.

It should be noted that there are also ghost camps. These are camps that have no cooking facilities. They are created in the hopes of receiving aid or by people who still worry about sleeping in their houses. In the latter case, the people spend the day at home and sleep in the camps. There is a very nice one in Delmas with about 400 families and a small clinic.

I hope this helps answer the charcoal cost questions that many have been asking.

All the best,

Nat of WorldStove

Lifeline to Haiti is a joint project between International Lifeline Fund (ILF) www.lifelinefund.org , WorldStove(WS) http;//www.worldstove.com , and local partners. The short term goals are to provide high-efficiency low-emission cook stoves to families affected by the recent earthquake. The long term goals are to establish a permanent locally owned and operated stove factory and distribution network in Haiti.

Our recent survey work in the IDP camps has indicated that fuel prices have undergone a 50% price hike since the earthquake. The inefficiency of local stoves, the increased cost of fuel and simultaneous decrease in earning options following the quake make the rapid implementation for the stoves a pressing concern.

International Life Line Fund is a Washington D.C. based nonprofit NGO. With years of experience in the implementation of stove programs in areas where fuel is a critical concern such as Darfur, Uganda, Kenya, and Tanzania. It is vital to have a keen understanding of how critical stoves are to health, economy, and the environment.

WorldStove is an expert in high efficiency cook stoves with projects in numerous countries around the world. . The stove selected for the Lifeline to Haiti Project is the LuciaStove. It specifically designed to eliminate the need of charcoal or wood. It ships flat to keep shipping costs at a minimum (1000 stoves can fit in a little more than a cubic meter) and can be easily assembled b y local skilled and unskilled collaborators creating desperately needed local jobs.

The LuciaStove boasts long life low emissions and the ability to use any waste plant, paper or cardboard as fuel. It does not burn the fuel but instead turns it into a clean (blue flame) burning gas with an energy content comparable to propane.

Local Partners are fundamental to both the short and long term success of the project for they help can identify the places of greatest need and assure that training, distribution and continual evaluation allows the stove program to have the greatest positive impact possible.

We have and continue to conduct survey both formal and in formal in new camps everyday. From Carefour Feuilles, Carefour, Petion Ville, Delmas, Plas Mai Gattes, and the informal camp Terren Aerport, it is clear that increased fuel costs, decreased earning options, a heavy dependence on charcoal and inefficient stoves are creating a severe burden on local households.

Local daily income, for the households that have income, varies between USD 3.12 and USD 5. Charcoal is most often sold by the “Marmit” (a large coffee can) and not by weight. Cost decreases with larger purchases further disadvantaging those with the lowest income. In general the cost of a Marmit is around 25 Goude (0.625 USD assuming an exchange rate of 40 Goude/USD). The increase in fuel cost has forced many families to go from three to one meal per day and a daily fuel expenditure of 62.33 Goude (1.56 USD). Considering that many households have lost all earning options and that this fuel cost is the equivalent of 31% - 50% of the daily income of those fortunate enough to have work, the current situation is clearly unsustainable and is forcing households to make the difficult decision between food and fuel.

Nathaniel.

Nat Mulcahy, World Stoves, March, 2010

Clearly pellets are the single best fuel option for Haiti right now.

Background

Ethanol stills use coal or wood, coal is not sustainable, and wood is vanishing fast. As for coal it is now being imported because local production and availability of wood is not able to keep up with demand and because much of Haiti is deforested. All fuel options underwent a 50% price hike following the earthquake. In ascending order of use the most common fuels are propane, kerosene, wood and coal.

Common Fuel Options in Quake Affected Regions

Haitian fire startersHaitian fire starters

Port au Prince uses 80% of all the coal consumed by Haiti. Wood, prior to the earthquake, was used mostly in rural areas but in many of the camps that we are working in we’ve noted more and more people using wood in their charcoal stoves. Kerosene is very expensive and used not for meals but for quick things like eggs or reheating precooked food. Following the fuel cost hike, however, I have seen more and more of the kerosene stoves gutted and transformed into small charcoal stoves by removing the tank and burner, pounding holes in some sheet metal for form a sieve to hold the charcoal and placing either a pot on the coals or using the rack or radiator from a refrigerator as a grill. As for propane it is used but the families in top 3% of the economic ranking.

Haitian Kerosene StoveHaitian Kerosene StoveKerosene Stove Converted to CharcoalKerosene Stove Converted to Charcoal

Regarding cost it is important to note that the drop in earning options and the spike in fuel costs now means that most of the displaced families now must spend 40% to 60% of the daily family income just to purchase fuel to cook with. In many cases this has meant that families have gone from eating two or three times a day to once a day even in the areas where WFP/PAM is sending distributing food.

What Other Options do we Have?

We could use fuels directly in the stoves which is one of the reasons I like gasifying stoves (fuel too small to use in a standard stove can be used in gasifying stoves); unfortunately the ability of gasifying stoves to use almost any biomass often creates misconception that all biomasses are the same. Users become disappointed when rice husks are used up faster than oak chunks. To avoid this I see briquettes and pellets as the best options. They are more consistent, clean to handle, low-cost, and perceived as a more modern fuel. This last is particularly important because many people are well invested in the “fuel ladder” and if they have already made the perceived social economic move forward (from wood to coal) they will not like to switch again unless it is to move up another rung. Marketing will be key to show that pellets and briquettes are a newer more modern fuel, it is important that pellets and briquettes not be viewed as taking a step back since they are made with “poor” materials.

Clearly pellets are the single best fuel option for Haiti right now.

1. What is the fuel offset by using the pellets? Is it 50% savings compared with wood?

wood fires here are either three rock stoves or charcoal stoves now being used with wood because many can no longer afford charcoal. efficiency is between 7 and 12 %maybe 20 % with some practice. pellet stoves require some training but then run themselves well and may be as much as four times more efficient. if you consider that 1kgofcharcoal produces here is really 7kg of trees the savings both economically and environmentally could be staggering

2. How much imported charcoal does it offset?

right now just one NGO's food program requires the use of 600,000 kg of charcoal a day, that's 1,800,000kg of CO2 per day give or take, right?and that is only one NGO hot meal program, put all the AID groups together and the numbers get big mighty fast

3. What are the relative costs of imported charcoal compared with pellets?

for now, thanks to Green Circle BioEnergy in FL we are providing free pellets to the people using our stoves. in general charcoal costs between 40% and 60% of a family's daily income. Daily income is about $5 US.

4. What is the benefit in number of meals from donated pellets? How may families could cook more than one meal per day by using donated or subsidized pellets as a transition fuel?

Green Circle Bio Energy's generous donation of 60 tons will provide 145,000 to 148,000 family meals, or feed about 740,000 people each once.
I strongly encourage other pellets producers to follow Green Circle's lead and in the mean time am working with the UN to see about funding regular shipments either weekly or biweekly to Port au Prince for the foreseeable future.
As a happy plus we have teamed up with three local ag and aforestation groups who will use the biochar produced by the stoves to restore soil carbon and help areas at risk of becoming desertified.

What Feed Stock Options are there in Haiti?

Feed stocks vary widely through Haiti but in the interest of simplifying logistics and keeping transport costs to a minimum I recommend that local pellets/briquette production be made using local materials. Clearly this means each small pellet mill or briquette press will have a specific optimal mix. UNDP and the Clinton Foundation have done a fine job with this concept and their briquette plant is now in its third year of operation. The use the Work for Pay model developed by UNDP for the collection of paper and cardboard throughout the city.

PaperPaper cardboardcardboardUNDP PelletsUNDP Pellets

These are then soaked in large drums and pounded in enormous wooden mortars to archive a consistent slurry prior to pressing. I would recommend the additional purchase of a hammer mill or two to accelerate production. We have measured a wide difference in hardness of the briquettes which makes the use of them harder to learn. This could easily be fixed with a grading protocol prior to the sale of the briquettes or controlling the pressing and packing procedure of the press.

Pellets would have the advantages of ease of use, faster production rates, no drying period (during the dry season the briquettes require three days to dry but during the rainy season drying can take as much as a week) and a wider variety of feed stock options to provide a more energy intensive fuel.

Around the quake affected region the feedstocks we have tested over the past five weeks have included, bagass, rice hulls, coffee hulls, bamboo, sawdust (many mills are working overtime to provide wood for shelters), chadek rinds, coconut shells and husks, mango cores, palm fronds, sugar cane, sugar cane shavings, paper, cardboard (personal thought, much waste has been generated during food and aid distribution, it would be nice to be able to use all of it so as not to leave a littered city in our efforts to help). All larger wood was used following the quake either for building shelters or to cook with.

wood chipswood chipsstrawstrawpalm frondpalm frondMangoMangococonut shellcoconut shellcorn cobscorn cobschadek rindschadek rindsfood aid packagingfood aid packaging

My favorite has to be chadek rinds, which by themselves produce a spectacular blue flame in the Luica Stoves. Chadek are large pear-shaped citrus fruits. And the rinds are saved as fire-starters.
Bagass poses some challenges in that the gas it produces often has sugars in it that do not always burn. This was not the case with the denser sugar cane shavings or the full cane chunks. Which leads me to believe that bagass, once pelleted would also function well. This, if verified would be a fantastic feedstock in that it is by far the most abundant in this area with mountains of it just sitting throughout the region.

Out side the quake affected areas there are a great many other feedstocks and the energy balance must be carefully made to see if any of these would make sense. From what I have seen vetiver grasses are clearly the most promising feed stock option followed closely by banana plantain plantation and processing waste.

Where to go from here?

For the short term and immediate future the best solution would be to import pellets. While the thought of importing fuel may cause some reservation it must be noted that current aid programs are importing charcoal to cook the food that is being distributed. Current food distribution of rice alone requires a daily supply of 600,000 kg of charcoal. Larger camps are importing propane. If the aid effort is already importing fuel would it not make sense to import more environmentally compatible fuels which at the same time would help sensitize Haitian stove users about a new fuel which could be sustainably 100% Haitian produced? We have enough pellets for the school feeding programs and some camps for the near future but a steady donor supply would be key as we work with WFP to establish up to 30 local pellet mills throughout the Port au Prince area.
Other askes could be small mills for schools, shipping and logistics help with donor pellets (getting the first shipment was a nightmare)and experts or pellet producers willing to consider production in Haiti, the market here is ready and the need for jobs here is great.

Our Stoves,

As for our stoves we are currently producing three types of stoves:

  • Large institutional stoves for the school feeding programs, orphanages, and hot meals programs in the camps,
  • Precut Flat packed Lucia Stoves with incorporated pot stand (1000 fit in a four foot cube and only bending is required to assemble them)
  • and a 100% local version of the Falt Packed LuciaStove made from oil drums. (there was a great feeling of pride when the local one out performed the lazer cut version)

Photos of all three are attached (please note on the large version that the local artisans we are working with insisted on decorating it with trees and birds saying they had to because if people use these stoves the trees will come back to Haiti and then so too the birds.

GrasifierGrasifier

Roger Samson was here tonight and we made and tested a Grasifier: a Switchgrass burning stove based on the dimensions of the Vesto adapted to make a lower cost pellet burning stove for Haiti.

Power, 2.5 kw
Burn rate 8-10 g/min
Mass 550 g
Fuel load 600 g though it can hold 750

Lighted with two caps of paint thinners
The flame went completely blue (just before the end) then wobbled a lot and went out.
When it went out there was no smoke indicating there were no volatiles left.

Time to fabricate, about 30 minutes.

I see this as a burner that can be attached to the centre of a Haitian charcoal stove to convert it into very clean burning a pellet stove.

Char yield: 25% of the initial dry mass.
Moisture content of the initial fuel, about 7%

Ash: nearly none.

Crispin

Nat Mulcahy, January 2010

Spent the day yesterday working with the state department to get more clearance for our shipments. 64 tons of pellets will provide food and clean water for 145000 families.

with 3,000,000 people displaced it will not last long. we are handing our the pellets and peanut shells in paper bags we have measured out to cook one meal or boil three pots of water. the paper bags are about the size one a lunch bag and the bag itself is the tinder to start the stove.

Spend the past two days working with NIH, EPA, The State Department, Haiti, USAID, and the World Bank. LuciaStove production is now set at 3000 per month but we keep being asked to ramp up to 5 to10 times that number.
Today we started casting the larger parts for the Biucci (the institutional version of the LucieStove), see attached. The more we make in haiti the more jobs we create here and the less we have to depend on the very sporadic shipping options.
