Who are we?

PT. Indo Asia Energy Development

Indo Asia Energy Development, Ltd (IAED) is an international development team of business and financial experts who have come together to build a world class commercial renewable energy company in Indonesia in the coming decade.

IAED believes there is a real and necessary opportunity to develop a large scale renewable energy industry in Indonesia. With petrochemical energy supply continuing to increase in financial and political cost, a real alternative to Indonesia’s energy and transport fuels needs are an urgent priority.


Who are we?

CV. Bali Komunika Internasional

(Bali International Consulting Group)

Is an international consulting group advising on sustainable development, corporate social responsibility, sustainability reporting, solutions for renewable energy and are now focusing specifically on the clean development mechanism under the Kyoto protocol.

At BICG, we advise our clients on project development with their social and environmental footprint in mind.

We work with selected international partners in Europe, Australia and Asia and recognize the GRI sustainability reporting guidelines as Indonesia’s first organizational stakeholder since 2006.


Advantages of GREEN Energy

  • Reducing the costs of purchasing energy (electricity and fuel)  
  • Additional profit from selling surplus electricity to the grid
  • Additional profit from selling

Biomass Syngas Power Plant

*information provided by technology provider


Biomass Syngas Power Plant

The biomass gasification system produces a valuable gas named producer gas - “Syngas” (Synthetic gas). The biomass (agricultural), used for this purpose is materials such as: rice stems, rice husks, cotton stalks, corn stalks, millet stalks, wood dust, cane trash, wheat straws, hemp palm husks and other forms of biomass. This system can produce electric power in the range of 400kW – 15.0MW by using a few parallel modular units.

Since Biomass itself is almost sulfur free, the gasification process will not produce any sulfur oxide emissions (SOx). However, fuels such as diesel and HFO contain a considerable amount of sulfur. HFO could have as much as 4% sulfur and therefore requires special additional treatment to neutralize these emissions.

Similarly the gasification of biomass produces very low concentrations (if any) of nitrous oxide emissions (NOx) when manufacturing the “Syngas” and thereafter leads also to low emissions in the combustion engines.

Biomass Syngas Power Plant

Production of 1 KW power, requires only 1.55 - 1.95kg of rice husks, wood dust or crop stalks as fuel. The water used in the cooling system of this process can be recycled after undergoing a simple treatment and thereby having no harmful effects to the ecological system and the environment. Self power consumption of this systems is low with percentages ranging between 5 - 8% of the generated total power.

This project is an ideal solution for regions where there are large quantities of biomass waste resources, mills, farms, nearby forests etc.

In consideration of the above mentioned particulars, the feasibility of such Power station will give a high ROI (Return of Investments) in a short period of time. The reasoning to this high ROI is due to the cost of the fuel being negligible – near ZERO (0), only labor, drying and grinding (if woods) has to be considered. In most other power stations, fuel cost corresponds to approximately 60-75% of power selling price, in our case, there is a saving of approximately 70% compared with other forms of power stations.

Biomass Syngas Power Plant

The technology of producing power by gasification of biomass is easy to operate, simple and economical in maintenances and service, has no high pressure steam/boilers, no turbines, easy to start, run standard combustion generator- NO STACK / CHIMNEY at ALL !!!

The power station requires a small land area to operate. It is environmental-friendly, simple to install, and it can gasify most kinds of agricultural biomass. These will in turn produce very low cost valuable electric power energy source.

In order to remove the soot, ash and tar particles in the biomass producer gas - “Syngas” and prevent the formation of secondary pollution to the environment, the biomass gasifying equipment effectively uses mechanical & electronic systems, which reduce the soot, dust and tar particle content in the produced gas to a certain extent, the equipment for collecting soot, ash and tar is highly efficient, it was designed and developed mainly for large-scale fossil-fuel power plants, chemical plants and waste incineration plants.

*information provided by technology provider


Biomass Syngas Power Plant

As the “Syngas” flow is relatively small in ordinary biomass gasifying generating projects, and there are some differences between biomass gas and the gas treated in fossil-fuel plants, temperature are low, less oxygen, therefore the adopting technology can solve most of biomass gasification demands.

Requirement of the feedstock granule size is ≤2cm, moisture content ≤20%, the whole project could be supplied with special drying system if needed, that can be done by using special dryer system which is heated by using the residual heat for drying.

*information provided by technology provider


Biomass Syngas Power Plant

Biomass pyrolysis gasification has different production ratio of soot and tar at different operating temperatures. If carbonization temperature is 400-600℃, the production ratio of tar is 13% - 37%, and it is 5% - 15% when using fixed bed gasification furnace, when operating temperature is 800℃, the production ratio in a fluidized bed gasifying furnace is about 2.5%. Tar content in raw Producer gas - “Syngas” without treatment is about 1 - 3 g/Nm3. The Syngas must be condensed to remove soot & tar before it is sent to internal combustion engine. As it is well known, the caloric value of tar is very high and it is about 30MJ/kg (7,140Kcal/Kg). The heat value of tar increases up to 10% of total heat value of gas.

“Syngas” standards shouldn’t have particulates more than 50mg/m3 which is the highest acceptable figure for internal combustion engines, some engine manufacturers also requires that dust/ash/soot content should be ≤ 25mg/Nm3, H2S≤10mg/Nm3.

In our gasification system, according to long practical field tests, output content of soot, tar ash and dust is < 23mg/Nm3 only.

What is the CDM?

The Clean Development Mechanism (CDM) enables countries that are signatories of the Kyoto Protocol to meet part of their GHG reduction commitment through projects located in another host country. Participation is on a voluntary basis and more and more Kyoto signatories have put in place the necessary administrative structures.

In the specific case of CDM, countries belonging to the

Annex I of the Kyoto protocol can fund and help implement projects in non-Annex I countries. Non-Annex I countries are typically developing countries.

Successful CDM projects generate Certified Emission Reduction credits (CERs), each CER representing a quantity of avoided GHG emissions in the non-Annex I host country, which are then transferred to the Annex I country.


Similar Projects approved

Around 15 projects registered so far



Based on similar projects the CERs can amount to ~500,000 for a ten year fixed period

Based on the Frauenhofer Institute CERs can reach Euro 20/CER by 2009; general market expectations Euro 25/CER

Over a 5 year term if feedstock supply can be guaranteed at USD 18 and below even without CERs more profitable compared to the use of diesel generators (constantly rising oil prices and high maintenance/replacement costs) in case of Vita Life Resort


Next Steps

  • Feasibility and environmental impact study to apply a 10 MW gasification biomass plant based on rice husk (mainly)
  • Validation of applicable technology
  • Assessment if the power supply is self-operated or in partnership
  • Identification of partners/investors
  • Options:
  • Independent Power Plant selling to PT. PLN @ 0.055/kWh
  • JV with Resort selling directly to Resort @ 0.12/kWh (no land investment cost)*4
  • Develop the PDD under the CDM for certified emission reductions
  • *4 Vita Life Resort project not yet financially closed

Additional Data
