Product Description

G2E provides a gasification technology solution for rural communities, in the form of biomass gasification plants which have a generation capacity of 15 kW up to 2 MW.

The purpose of the biomass gasification plant is not only to produce electrical energy but to polygenerate and produce electricity, heat and gas. During the power generation process, there is the possibility to produce biochar as an alternate product. Biochar is composed of 80% carbon and can be used for soil enhancement. Biochar is a way to fix CO2 in soil for hundreds of years, therefore it is a carbon-negative energy. (Watch an introduction video to biochar.)

G2E adapts the solution to the customers’ needs and to the biomass that is available. G2E has a biomass gasification demonstration center in Mexico City, with 4 gasifiers with different features to evaluate/compare technological and energy performance of different biomass feedstocks and technology modifications.

Green to Energy is located in Mexico City, Mexico.

Competitive Landscape

Direct competitors include Green Heat Biogas Digester, Nopalimex, and ARTI Biogas Plant.

Manufacturing/Building Method

The technology is being produced in Asia. For the demonstration center, the four gasifiers were manufactured in India (2), China (1) and the United States. G2E is a licensed distributor for all the biomass plants. However, G2E improves the plants using their expertise, making possible the use of various types of residual biomass. Interview with representative As of July 2016, G2E plans to produce products in Mexico. Interview with representative

Intellectural Property Type


User Provision Model

Users can contact G2E to get information, advice, and support. For rural areas, G2E relies on subsidies to install the product. For businesses, they evaluate the point of profit of the technology, depending on the type of plant and biomass used. Interview with representative

Distributions to Date Status

As of July 2016, there are three projects in Mexico. Customers include three corn seed producers and one tequila distillery.  

Power rating (W or kW)

Design Specifications

The biomass demonstration center consists of 4 gasifiers with different primary fuel and technology modifications. Two of them are manufactured in India: combo-40 and PG-45. The center also carries auxiliary equipment for the preparation of biomass, consisting of pre-treatment equipment including driers and compactors for briquetting as well as water scrubbing for the cleaning of synthesis gases (one of the gasification technologies) and a motor with internal combustion, loaned by the company Cummins. Among the several types of biomass residues tested, corn cob and coconut have proven to be more efficient. They do not require pre-treatment and produce high-quality gas that does not need scrubbing. Interview with representative [caption id="attachment_19814" align="alignnone" width="300"] Biomass plant 3 (made in India)[/caption] [caption id="attachment_19813" align="alignnone" width="300"] Biomass plant 2 (made in India)[/caption] [caption id="attachment_19812" align="alignnone" width="226"] Biomass plant 1 (made in USA)[/caption] [caption id="attachment_19811" align="alignnone" width="300"] Briquetting machine[/caption]

The average lifetime of a plant is 25 years.

Manufacturer Specified Performance Parameters

Designer specified performance targets include affordable and modular.

Vetted Performance Status

G2E estimates that the conversion efficiency of biomass into syngas is 80-85%, of syngas into thermal energy is 90%, of syngas into electrical energy is 35% and of biomass into biochar is 10-12%. Interview with representative


There are some potential dangers operating the biomass plant: noise, hazardous waste material disposal, voltage.

Complementary Technical Systems


Academic Research and References


Compliance with regulations


Evaluation methods

Testing was completed by the manufacturer at their demonstration center in Mexico City to determine conversion efficiency of different materials.

Other Information

G2E receives funding from Universidad Nacional Autónoma de México (UNAM) and SAGARPA, Secretaría de Agricultura. The offices and warehouses were built based on containers and recycled material, with the idea of matching the use of "material" of little value. The office has a classroom-auditorium for dissemination and training.
