How we do it?
The TwoStage Gasifier (MM-G101C): This gasifier design is widely acknowledged to be the most efficient and well-documented in the market and the TwoStage gasification technology was initially developed at DTU Chemical Engineering by Ulrik Birk Henriksen. As indicated by its name, it features two separate stages – pyrolysis and gasification (see picture below). In separating the stages, a wealth of advantages is gained including high efficiency, flexibility and drastically reduced maintenance due to the elimination of the tar issue mentioned above.
Unlike many other sustainable energy solutions (solar, wind, boilers), the gasifier is extremely flexible and compact. The system is fully contained (aside from the feedstock storage area) in a 20-foot container, which can be easily moved if necessary. Also, the energy output is on-demand, meaning that the gasifier will provide power when the sun has set and the wind is unavailable.
The machine has a capacity of approx. 1.4 tonnes/day of feedstock that can have a moisture content of up to 58% (using an in-built steam dryer) to produce 80kW electricity. This translates to a high conversion of ~33% from feedstock to electricity (with a cold gas efficiency of >90%). Around 10% of the input remains as char. The system is highly optimized for heat recovery and is built for continuous operations.
The practicality of the solution thus allows for:
- Decentralized, on-site production of electricity for waste generators and aggregators
- Micro-grid setups in remote areas where last-mile connectivity is poor or unstable
- Setting up off-grid EV charging stations and much more…
