Biomass Energy

Biomass Sector

  • Biomass from wood sources accounts for over 70% of the primary, non-electricity, non-transport energy demand for Kenya.
  • According to the UNFCCC, Kenya’s biomass fuel is calculated to be 92% non-renewable. In part this can be attributed to the increasing demand for biomass fuel from an increasing population: the population of Kenya increased by 9 million from 28.7 million in 1999 to 37.7 million in 2009.
  • This increase, coupled with the unsustainable use of forest resources, exacerbates the problem of managing Kenya’s growing emissions profile. In fact, Kenya’s wood deficit is projected to increase from 10 million m3 to at least 15 million m3 per year by 2030.
  • For example, a national study on charcoal in Kenya by ESDA (2005) estimated that annual production was 1.6 million tons. Production has since risen to 2.5 million tons, an increase of 156% within eight years (or almost 20% growth per annum).

Bioenergy generation and regeneration using modern technology as well as management is critical to ensuring sustainability of supply to meet the growing demand. The continued overreliance on bioenergy as the primary source of energy and the lack of commensurate effort in developing the resource threatens achievement of the 10% constitutional requirement for forest cover.

Managing role of biomass

  • Biomass fuels are the most important source of primary energy in Kenya with wood fuel (firewood and charcoal) accounting for 68 % of the total primary energy consumption. About 55% of this is derived from farmlands of woody biomass as well as crop residue, animal waste and the remaining 45% is from forests.
  • In spite of past efforts to promote wood fuel substitutes, the number of people relying on wood fuel is not decreasing. Consequently, wood fuel will continue to be the primary source of energy for the majority of the rural population and urban poor for as long as it takes to transform the rural economy from subsistence to a highly productive economy.

Charcoal

  • Over 82% of the urban population in Kenya and 34% of rural households use charcoal a demand is increasing. The sector has an estimated value of KES 80 Billion (FAOSTAT) with livelihood support of about 2.5Million Kenyans (ESDA, 2005).
  • National charcoal supply is estimated at 7 million m3  while demand is estimated at 16 million m3 at a per capita of 0.3915, this leaves a supply gap of close to 9 million m3
  • To manage the supply gap, it’s important to have sustainable charcoal production practices like efficient wood to charcoal conversion technologies and encourage on farm plantation. On demand side, there is need to adopt fuel-efficient stoves and cooking practices that minimize fuel use like covering pots while cooking to retain heat.

Some sustainable charcoal production initiatives include

  • Training of charcoal producer groups on Charcoal Regulations 2009,
  • Introduction and creating awareness on efficient conversion technologies
  • Counties are also developing charcoal/environment legislation  like Kitui, Narok  , Kajiado etc
  • Exploring use of invasive species like Prosopis Juliflora in Baringo county by KEFRI and other stakeholders.

Briquettes and pellets

  • Kenya’s Draft Strategy and Action Plan for Bioenergy and LPG (MoE&P 2015) aspires to “mainstream” briquettes and pellets as viable alternative fuels for residential and industrial end-uses. The strategy proposes to develop quality control and standards, provide technology transfer, and incentivize business and technical development services for domestic briquette and pellet enterprises.
  • Biomass briquettes can offer an alternative fuel for many of these applications. Biomass briquettes are a form of solid fuel that can be burned for energy. They are created by compacting loose biomass residues into solid blocks for domestic and institutional cooking and industrial heating processes. Briquettes can be made from biomass residuals such as charcoal dust (which is waste from the production process), coffee husks, coconut husks, maize cobs and sawdust amongst others. Briquettes have the potential to be a source of renewable energy, if they are made from sustainably harvested biomass or agricultural residues.
  • There are several initiatives and studies that are being undertaken by stakeholders to promote briquette. Innovator are also coming up with machines for making briquettes.

Some projects & studies

Project/Implementer Description
Scaling-Up Briquette Commercialization In Kenya. Practical Action, ETC Foundation, EEP. 2013-2015 Project was to increase accessibility to briquettes as alternative affordable cooking fuel to at least 40,000 consumers in Mombasa, Nairobi, Nakuru and Kisumu counties leading to re-use of waste biomass. Over 77.2 tonnes of fuel briquettes were produced and sold which is equivalent to over 231.6 tonnes of lamp charcoal hence avoiding over 2084.4 tonnes of CO2 emission from being released to the atmosphere. 4604 units of improved Cookstoves were sold with over 6000 domestic consumers (households), 106 institutions (schools & children’s homes), 183 restaurants (food vendors, eateries), and 65 others (hatcheries, individuals) benefiting from use of fuel briquettes to meet their energy needs.

Study & Reports

Project/Implementer Description
Kenya Briquette Industry Study, 2010 GVEP (now Energy4Impact) under Developing Energy Enterprises Programme(2008-2013) The study was to understand the current and potential impact of micro-scale briquette producers on rural and peri-urban energy access. Study areas were Ranen in Nyanza, Mariakani in Coast, Nairobi and Nyeri.
Capital Access for Renewable Energy Enterprises Project by SIDA and Energy4Impact( formely GVEP) Assessment of the Briquette Market in Kenya 2013: This study assessed 35 enterprises; key findings were briquette sector can be promoted by building technical capacity and having focused market development activities.

Resources

  • Farm residue is used to supplement scarce wood energy required for domestic needs.
  • In year 2000, sources of biomass residue in Kenya included;
    • maize 1.6 million tons/yr., Sorghum 76,000 tons/yr., wheat 42,000 tons/yr., millet 46,000 tons/yr., beans 77,000 tons/yr., rice 1,000 tons/yr., cassava 12,000 tons/yr., coconut 6 tons/yr., cashew nut 2tons/yr., coffee 300,000 tons/yr., tea 60,000 tons/yr. and sisal 8,000 tons/yr. (Biomass Energy Resources in Kenya, 2012).
  • Wood waste is mainly used in urban areas by 3.7% of households as compared to 2.1% in the rural areas. The consumption is about 15,600 tons equivalent to 23,088m3 (1.48m3/ton), estimated from industrial by-product production (sawdust, timber rejects, off-cuts etc.) (Gender, Improved Cook Stoves and Development in Kenya, 2010)

Pellets

Though briquettes have gained traction in some niche markets, there has been little development of pellet fuels in Kenya, particularly for the household market. Pellets burn cleanly especially when they are used with advanced forced-draft stoves. Pellets are manufactured under high pressure, they are denser than briquettes – with lower moisture and ash content – and they can be economically transported over longer distances. However, pellet businesses face several obstacles. For example, pellet production requires higher capital investment. In addition, for household use, pellets require specialized stoves, while briquettes can be used in common stoves like the Kenya Ceramic Jiko, or KCJ. These barriers may explain why few pellet projects have been implemented in Kenya to date. Nevertheless, as household energy becomes more commercialized and Kenyan consumers become more comfortable with advanced stoves, there may be a place for pellets in the Kenyan market.

Some pellet projects

Project/Implementer Description
SNV- 2014-2016 SNV implemented a project to increase access to and use of clean and efficient forced draft pellet stoves in urban and peri-urban markets. It covered Nakuru, Nyeri, Nyandarua and Kisumu. About 1,500 stoves were sold along with roughly 10 tonnes of pellets. Through a market based approach
ECOZOOM, GACC Ecozoom implemented the project in Kisumu and Siaya counties in Western Kenya. Working with a network of Community Health Volunteers, they recruited 85 households in Mamboleo, Nyalenda, and Karapul, representing peri-urban, urban informal, and rural settlements respectively

Quality Control

Kenya is yet to develop a guideline on the quality of pellets that can be produced within the country. However, European Standard parameters threshold include:

Parameter Classification
Size (D – diameter and L – length) (mm) D06: D ≤ 6 ± 0.5 and L ≤ 5D
D08: D ≤ 8 ± 0.5 and L ≤ 4D
Moisture content (%) M10: ≤ 10%
Ash content (%) A0.7: ≤ 0.7%
N (%) No guideline is included
S (%) S0.05: ≤ 0.05%
Cl (%) No guideline is included
Durability DU97.5: ≥ 97.5%
Fines content (% < 3.15 mm) F1.0: ≤ 1%
F2.0: ≤ 2%
Bulk density (kg/m3) No guideline is included
Heating value (kcal/kg) E4.7: ≥4.7 kWh/kg = 4042 kcal/kg
Additives < 2%

Advantages of Briquettes and Pellets

  1. Using briquettes and pellets for electricity generation makes business sense
  2. Briquettes and pellets use enhance environmental protection
  3. Briquette and pellets business offers communities in Kenya opportunities for economic empowerment
  4. Briquettes and pellets offer a plausible alternative household energy solution to solid wood fuel
  5. There is need to ensure quality of the products in the Kenyan market
  6. With sufficient business and technical services support, the briquette and pellets for energy sector in Kenya will scale up (source; Bioenergy- Briquette and Pellet Strategy; MOEP and CCAK)

Biomass for electricity generation

  • A private company Tower Power had expressed interest to set up a 250 MW biomass based power plant in Baringo County to utilize the invasive species tree Prosopis Juliflora.
  • The FiT policy provides for biomass energy resource generated electricity with a firm power fixed tariff not exceeding US Cents 10 per Kilowatt-hour of electrical energy supplied in bulk to the grid operator at the interconnection point. Under this policy, 18MW cogeneration project for use of cane bagasse at the coastal region of Kenya has been approved
  • The Government has identified the existence of a substantial potential for power generation using forestry and agro-industry residues including bagasse. The total potential for cogeneration using sugarcane bagasse is 193MW.
  • Mumias Sugar Company (Independent Power Producer) generates 35MW out of which 26MW is dispatched to the grid. However, opportunities within other sugar factories estimated to be up to 300 MW have not been exploited.
  • A private company Tower Power had expressed interest to set up a 250 MW biomass based power plant in Baringo County to utilize the invasive species tree Prosopis Juliflora.

Cooking Technologies

Biomass use for domestic, institutional and industrial use continues to provide a large percentage of energy needs.  At a domestic level an average household is estimated to consume 9kg of biomass per day. At an industrial level, for instance a medium tea factory biomass requirement is estimated at 20 tonnes per day.

Institutional

There are approximately 70, 000 institutions including prisons, learning institutions hospitals, hotels and restaurants in Kenya each consuming about 270 tonnes of wood fuel per year; and majority of the small and medium enterprises such as hotels, food vendors and small scale processing facilities use biomass as the primary source of energy. There are over 90 tea factories in Kenya consuming an average of 10,900m3 of wood fuel per year; about 550,000tons of fuel wood per year.

Institutions like adopting fuel efficient stoves as industries make efforts to obtain boiler with better fuel usage. The search for alternatives like briquette for industries is evident while other like KTDA(Kenya Tea Development Authority)  are developing micro hydro initiatives.

Domestic

There are several biomass technologies in market today. The technologies range from those which burn solid biomass directly into heat to those convert biomass into liquid or gaseous fuels before burning them into heat.

By 2013, the Kenya Country Action Plan the estimates were that 3.2 million households were accessing improved cookstoves. MOEP and stakeholders target is to reach 5 million Kenyan households and institutions with improved cookstoves for cooking and heating applications by 2020.

  • The private sector, development partners and government is making efforts in stove manufacturing; distribution, creating awareness, facilitating financing and more so ensuring a market –based approach is adopted in the cook-stove sector.
  • The sector is estimated to create 3,000 direct local manufacturing jobs with 300,000 stoves sold in a year
  •  CCAK (Clean Cook-stoves Association of Kenya) estimated that under VAT zero rated regime, cookstoves worth 1.7 million shillings will be sold from 2017-2020. This is an equivalent of 3.4 million trees saved per year from 2017-2020. The equivalent consumer savings on fuel will stand at 53 billion shillings (2017-2020) which can be spent on other sectors of the economy while 5 million metric tonnes of carbon will be saved (2017-2020).
AdamRetort
  • Only 37.2% of Kenyans cook with clean and efficient stoves.
  • Kenya‘s Green House Emissions can be reduced by the adoption of Clean and Efficient Stoves i.e. 1 Stove Saves over 3 Tonnes of Carbon per Year.
  • Clean cookstoves save over 50% in fuel consumption. An average household will save 13,000 shillings annually. Savings will increase under favourable policy due to increased adoption
  • Government targets 100% access to clean and efficiency stoves by 2030
