With over 50 years of experience and more than 5000 biomass gasification systems operating worldwide, Alternative Energy Solutions International, Inc. (AESI) and Uniconfort have evolved biomass energy into a clean, efficient, money-saving, renewable energy replacement for costly fossil fuels. AESI is the exclusive OEM of the Italian-designed Uniconfort biomass gasification technologies in the United States, Canada, Mexico, and South America.

Modular Power Generation

Biomass to Energy

Requests for biomass generated electricity will generally fall into one of two categories.

  1. Power plants purposed to make electricity for commercial sale to a grid.
  2. Power plants as enhancement to another primary driver.


AESI has used our substantial experience in Biomass To Power to derive very robust, long lived, modular solutions for our industrial, commercial and institutional customers. These solutions come about from our four primary features:

  1. The ability to accept varied types of biomass, which remove the requirements to only use wood.
  2. The use of gasification/combustion versus burning, which is an optimal conversion and cleaner.
  3. Maintaining a total modularity, which increases quality and speeds deployment.
  4. Coupling proven, low maintenance, highly reliable, and durable electrical generation solutions leading to a first cost of a biomass system that lasts 40 years that is far less than the cost of operations and maintenance.


Our system solutions are very deliberately designed, focused and are an AESI trademarked, replicating, approach which we refer to as EWES.   AESI’s design approach is anchored in the definitions below. The ability to accept varied biomass fuels in our Vertically Integrated Gasification & Combustion (VIGC) boilers while producing steam differentiates AESI from other providers

Just Electricity

Designing and constructing commercial power plants to on sell electrical power is a significant undertaking and public utilities will spend upwards of $17,000 per kwe to develop one.

Selling commercial power usually requires a front end agreement, performance of an interconnection study, preparation of a plan to enable connect, penalties for missing minimum delivery’s, penalties for not meeting delivery stability factors, and others.

Above all, the commercial power plant, which has a single revenue stream, needs to maximize delivery from core equipment, which demands high pressure steam turbines, heat recovery systems, sophisticated control packages and more.

Making and using high pressure steam introduces several operational challenges. Such plants are expensive, more complex, and higher risk. The only effective method to reach needed pressures is through a hybrid boiler with enhancements. All plant pressure containing components have to be constructed of high strength materials, frequently alloys, increasing costs; as steam pressures rise, so do the risks which in turn increases the training and safety requirements on plant operations.

Accessory Power

Delivering electricity as part of a total system investment solution is what AESI delivers in modular packages. CHP or garnering both heat and power from biomass to energy systems is intuitively a preferred project approach. Savings on Energy is and will continue as a major driver of capital spending plans for Biomass Systems, affording benefits in both venues optimizes the plant investment.
