Kenworth+Brayton+Capstone=ICR350: The Game Changer

<For heavy-duty class 8 trucks, the Kenworth Truck Company will demonstrate a hybrid-electric drive system that uses a natural-gas-powered micro-turbine. The goal of the project is to make cost and efficiency improvements to the hybrid system and its batteries. The system will use an intercooled recuperated (ICR) 350 kilowatt microturbine that will be run on natural gas because of the fuel’s low emissions and low cost.

FedEx will take delivery of the demonstration truck and integrate the vehicle into its on-going operations starting in 2012. The test vehicle will be equipped with data-logging equipment to record information on the vehicle’s operation for analysis.

The system will initially be designed for class 8 trucks, but can be readily scaled to fit all class 6, 7, and 8 vehicles over a wide range of operations. Kenworth projects that this technology will be commercially viable in 2013.

Grant Amount


Match Funding

$1,603,325 from the project’s participants.

Project Participants

Kenworth Truck Company, a leading manufacturer of heavy and medium duty trucks, will serve as the technical lead and developer for this project.

Capstone Turbine Corporation, headquartered in Chatsworth, California, will provide the microturbine and demonstration support.

Brayton Energy LLC, an engine research and development firm, will provide technical support.

Arvin Meritor, a truck drive train component supplier, will provide the class 8 Dual Mode Hybrid Drive system.

Southern California Gas Company will provide technical and marketing oversight, and fuel management support.

Clean Energy, the largest provider of natural gas fuel for transportation in the US, will coordinate fuel delivery for this project.

Global shipper FedEx Corporation will conduct the field test for this project.

CalStart, a non-profit organization focused on the growth of clean transportation, will provide program management for this project and will coordinate all activities of the project team.

Project Benefits

This project can reduce greenhouse gas emissions by 46 tons and diesel fuel by 13,800 gallons per truck per year. At full commercialization, this project can create over 6,000 high tech and green tech jobs on a sustainable basis in California by 2025 to 2030. Six hundred California jobs per thousand units are projected just for the microturbine manufacturing and assembly.

<ICRTec was selected from over 300 presenting companies for one of two Outstanding Venture Awards at the recent NREL 2011 Clean Energy Venture Awards, sponsored by Wilson Sonsini Goodrich & Rosati. ICRTec is Brayton’s partner in the development of the Next Generation Microturbine, a 350 kWe, a high efficiency intercooled recuperated gas turbine with a ceramic hot section. NREL is the U.S. Department of Energy’s (DOE) primary national laboratory for renewable energy and energy efficiency research and development. NREL is operated for DOE by The Alliance for Sustainable Energy, LLC.>

<ICRTec owns the alternative to traditional diesel power – an innovative, fuel efficient, low emission and fuel flexible gas turbine engine that competes in the North American $14 billion diesel engine market.

An engine alternative that North America needs – now.

The ICR350 is cleaner burning and more cost effective than the best diesel engines today. It emits less than one-eighth of the NOX/particulate emissions allowed under EPA 2010 regulations with better fuel economy and lower greenhouse gas (GHG) emissions than diesels.

ICRTec Power. Clean and Simple

Our seasoned management team and best-in-class development team are focused on the engine.

We work with original equipment manufacturers and integrators in each market to deliver solutions that will easily surpass current emission standards without compromising size, weight, cost and fuel consumption.

We can show significant improvements in fuel efficiency and cost of ownership when compared with today’s leading diesel engines whether the fuel of choice is diesel, natural gas or any other fluid combustible.

We welcome inquiries from OEMs and integrators looking to improve the performance of their customer solutions.

Gas turbines are the engine of choice in applications where reliability and durability are of primary importance. Turbines are cleaner, smaller, lighter and quieter than comparable reciprocating engines. In a world where low emissions are expected, turbines are simply superior to their reciprocating counterparts.

The ICR350 is a significantly improved version of earlier gas turbines.

Until now, industrial gas turbines have never been sufficiently developed to yield efficiencies higher than about 38%, nor have they ever been built with such a high power-to-weight ratio as the ICR350.

Turbine technology is not new; what is new is a unique arrangement of simple turbomachinery modules with a proprietary ceramic turbine rotor and heat exchangers resulting in high specific power.

The breakthrough allows our engine to achieve thermal efficiencies above 40% today and we expect it will be the first gas turbine to cross the 50% threshold, making its fuel economy and related emissions dramatically better than the best diesel engines of comparable size.

The ICR350 is the first engine to provide the benefits of gas turbines at a power density and cost that will appeal to price sensitive markets.

Our proprietary and patented improvements make ICRTec the market leader in this development area.

Why Turbines?
Proven Reliable Technology

Turbines are the engine of choice where high reliability and durability are of primary importance. Aircraft, military and electrical generation are examples of existing applications dominated by turbines.
Smaller and lighter than comparable diesels

The compact size and weight provides more flexibility when designing solutions around the engine. Renewed emphasis on heavy duty vehicle fuel consumption requires smaller, lighter engines.
Fuel Flexible (all commercial and renewable fuels)

Volatility in fuel prices makes flexibility a valuable cost management tool. Market incentives to transition to natural gas and renewable fuels favor a flexible alternative to traditional diesel power.

Products of combustion never contact the lubricating system. No oil, fluid or urea reservoirs to fill/change. Few moving parts. Maintenance intervals and engine life are greatly extended over the comparable diesel.

Turbines experience almost no vibration resulting in quieter operation than a comparable diesel.
Lower Operating and Support Costs – Superior Return on Investment

Low lubricant cost and consumption; long service intervals; long life; and flexible fuel choice translate to operating cost savings. >
