G2E Biomass Gasification Plant
Green to Energy
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 C02 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.
G2E (Green To Energy) implements the technology.
Each solution is adapted to the user and the biomass used. Biomass plants can range from USD 60,000 to USD 1,000,000.interview with representative
Target users are rural communities and industries with biomass waste in Mexico. In communities, G2E installs one biomass plant per village.interview with representative
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’s plans are to produce in Mexico.interview with representative
The manufacturers have patents for the biomass plants, G2E is a licensed distributor.interview with representative
As of July 2016, there are three projects in Mexico. Customers include three corn seed producers and one tequila distillery.
Watch the demonstration centers with the 4 gasifiers in Mexico City.
– The biomass demonstration center includes:
– – 4 gasifiers with different primary fuel and technology modifications; two of them are manufactured in India, combo-40 and PG-45;
– – Auxiliary equipment for the preparation of biomass: pre-treatement includes driers and compactors for briquetting;
– – Water scrubbing used for cleaning of synthesis gases (one of the gasification technologies);
– – 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)
Depends on the type of primary fuel and technology modifications made.
G2E provides support to the users.interview with representative
G2E provides replacement parts.interview with representative
– G2E estimates that the conversion efficiency:interview with representative
– – of biomass into syngas is 80-85%;
– – of syngas into thermal energy is 90%;
– – of syngas into electrical energy is 35%;
– – of biomass into biochar is 10-12%.
A theoretical analysis by G2E estimated that 4.5 kilograms of agave bagasse or coconut fiber could generate enough electricity to replace 1.3 liters of diesel or 1.8 liter LPG energy.
The report also shows that a megawatt of installed capacity biomass gasification avoids the emission of three thousand 500 tons of CO2 annually.
There are some potential dangers operating the biomass plant: noise, hazardous waste material disposal, voltage.
Trials in the demonstration center in Mexico City.
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.
