Alter NRG delivers a complete plasma gasification solution to its customers, that utilizes its Westinghouse Plasma Torches. With our engineering and construction partners we can design and construct a complete gasification plant, assisting with technical and commercial support during the entire project development process. Our engineering and construction partners can offer performance guarantees on the entire project facility which truly sets up apart from other earlier stages technologies.
Components for a successful Technology Deployment
The performance & evolution of the Westinghouse Plasma technology is contributed to, by a wide range of external collaboration. By leveraging relationships, Alter NRG has expanded the product offering to a market ready application.
Engineering and Construction Relationships:
We have relationships with world class engineering firms and operators who can provide certain requisite performance obligations on projects. We provide a fabricated plasma gasification system. The major components are included in our scope of supply, while the balance of the plant engineering is completed by an engineering partner.
We have existing well capitalized, innovative plasma gasification customers actively developing projects that are designed to meet their strategic business objective. They are currently advancing projects, including three under construction.

Commercial Operating Plasma Torches for over 20 years:
The Westinghouse Plasma torch provides flexibility and allows control over temperature, independent of fuel or oxygen throughout in the process.
MARC 3A Plasma Torch
WPC’s standard MARC 3A configuration operates in a range from 80kW to approximately 300kW. The current to the field coils in the MARC 3A is in series with the arc current. The MARC 3A does not feature independent control of the field coil current and arc current.
MARC 11 Plasma Torch
The MARC 11 torch power is controlled by changing either the arc current, field current or the process gas flow. Torch connections include quick disconnects for the air supply, cooling water and electrical connections to facilitate torch removal for inspection and maintenance. WPC has two standard MARC 11 configurations, a low power torch, the MARC 11L and a high power torch, MARC 11H. The low power MARC 11L plasma torch operates in the range from approximately 350 kW to approximately 800 kW.
The high power torch operates in the range from approximately 860 kW to 2400 kW. The maximum arc current of the MARC 11 plasma torch is 2000A. The MARC 11 torch uses two separate power supplies: one for the field coil and one for the arc. The arc current and the field coil current can be independently controlled.
MARC 4.5 Plasma Torch
Like the Marc 11, the MARC 4.5 torch power is controlled by changing either the arc current, field current or the process gas flow. Torch connections include quick disconnects for the air supply, cooling water and electrical connections to facilitate torch removal for ease of inspection and maintenance. The Marc 4.5 plasma torch has an operating power range of 280 kW to 530 kW. The MARC 4.5 is designed to have a variable custom fabricated length to fit a variety of different gasifier designs. The maximum arc current of the MARC 4.5 plasma torch is 650A. The MARC 4.5 torch uses two separate power supplies: one for the field coil and one for the arc. The arc current and the field coil current can be independently controlled.
