Algae and cellulosic biofuel supported in U.S. federal tax act

03-Jan-2013 14:35 GMT

The Biotechnology Industry Organization (BIO) is expressing gratitude to the U.S. Congress for including extensions and modifications of the Second Generation Biofuel Producer Credit and the Special Allowance for Second Generation Biofuel Plant Property in final passage of the American Taxpayer Relief Act of 2012. The Act will incentivize investment in both cellulosic and algae biofuel production by renewing a $1.01 per gallon tax credit for producers and accelerated depreciation for newly constructed facilities during 2013, and modifying these credits to include algae. Said Brent Erickson, Executive Vice President of BIO’s Industrial and Environmental Section, in a Jan. 2 statement: “We thank Congress for extending the producer tax credit and bonus depreciation and enabling algae producers to qualify. Stability in such policies is crucial to maintaining private investment. We hope to work with Congress in the coming year to extend and maintain additional policies that support this innovation, such as a strong energy title in any upcoming Farm Bill, and the Renewable Fuel Standard.”

Rolls-Royce to power U.S. Navy’s new Ship-to-Shore Connector hovercraft fleet

22-Oct-2012 15:18 GMT

Rolls-Royce won a contract to power the U.S. Navy’s future fleet of hovercrafts, known as the Ship-to-Shore Connector (SSC). It will work with Textron Marine & Land Systems, which has been selected to build the initial development craft, in a program that could extend to 73 craft. The SSC will replace the Navy’s current fleet of Landing Craft Air Cushion (LCAC) hovercraft over the next 20 years. The new hovercraft will be used to rapidly deploy personnel and vehicles between U.S. Navy ships and the shore. Each SSC will use multiple Rolls-Royce MT7 gas turbines, derived from the AE1107 engine, which powers the U.S. Marine Corps ’ V-22 Osprey tilt-rotor aircraft. Rolls-Royce will also design and manufacture the air intake and exhaust systems.

ATK Awarded $50 Million Contract for NASA's Advanced Concept Booster Development for SLS

22-Oct-2012 15:09 GMT

NASA has awarded ATK a $50 million contract to complete engineering development and risk reduction tests as part of the Advanced Concept Booster Development for the Space Launch System (SLS). ATK's effort focuses on overcoming key technological challenges in developing advanced booster requirements for NASA's SLS program. Tasks within the scope of ATK's award include development of a lithium-ion battery-powered electric thrust vector control system; high-performance propellant; lightweight composite rocket motor case; and an advanced nozzle. All of these developments will culminate with an integrated booster static test firing of these technologies. All of these tasks use cost-saving processes and materials that reduce cost and help lower risk as NASA moves toward a higher-performing booster in the future.

Algae.Tec, Lufthansa agree to build biofuel production facility in Europe

09-Oct-2012 21:05 GMT

Algae.Tec and Lufthansa signed a collaboration agreement for the construction of a large-scale algae-to-aviation biofuels production facility. The site will be in Europe adjacent to an industrial CO2 source. Lufthansa will arrange 100% funding for the project. Algae.Tec will receive license fees and profits from the project, which will be managed by Algae.Tec. As part of the agreement, Lufthansa commits to a long-term offtake agreement of at least 50% of the crude oil produced at an agreed price. The agreement forms the base for a long-term cooperation between Algae.Tec and Lufthansa for the industrial production of crude algae suitable for conversion into aviation kerosene and conventional diesel fuels.

Pratt & Whitney acquires Rolls-Royce’s share in IAE

07-Jul-2012 20:36 GMT

Pratt & Whitney finalized an agreement to purchase Rolls-Royce's program share in International Aero Engines (IAE). IAE is a multinational aero engine consortium whose shareholders now consist of Pratt & Whitney, Pratt & Whitney Aero Engines International GmbH, Japanese Aero Engines Corp. (JAEC) and MTU Aero Engines GmbH. To date, more than 5000 V2500 engines have been delivered, and nearly 2000 more engines are on order with close to 200 customers around the world. As well as restructuring participation in IAE, on Oct. 12, 2011, Pratt & Whitney and Rolls-Royce also announced the formation of a new collaboration to power future midsize aircraft, which is subject to separate regulatory approvals. IAE partners JAEC and MTU have also agreed to join this new venture.

PW1400G engine to be offered for MC-21 aircraft family

18-Jun-2012 15:11 GMT

Pratt & Whitney and Russia's Irkut Corp. signed a definitive agreement to offer the P&W PurePower PW1400G engine on Irkut's MC-21 family of aircraft. This agreement makes the PurePower engine the only western powerplant offered on the new narrow-body program. P&W and Irkut selected Short Brothers plc, a subsidiary of Bombardier Aerospace, as the exclusive nacelle provider for the PW1400G engine family. Irkut is developing the MC-21 as a family of 150- to 210-passenger aircraft with first flight of the PurePower PW1400G engined aircraft planned for 2015 and entry into service in 2017. The MC-21 series will feature on aircraft with 25,000-32,000 lb of thrust. The PurePower PW1000G series engines use an advanced gear system allowing the engine's fan to operate at a different speed than the low-pressure compressor and turbine.

Orbital to supply FlexDI engines to AAI

29-May-2012 20:07 GMT

Orbital has been contracted to supply heavy-fuel engines for use in AAI Unmanned Aircraft Systems' Aerosonde Small Unmanned Aircraft System (SUAS). AAI recently won significant military contracts from the U.S. Navy and Special Operations Command to provide SUAS fee-for-service operations utilizing the newest configuration of its Aerosonde SUAS. Orbital, headquartered in Perth, Western Australia, is contracted to supply engines up to a value of approximately $4.7 million throughout 2012. This new engine and system uses Orbital's FlexDI Engine Management system to enable spark ignition operation of heavy fuels such as JP5 (naval operations) and JP8 (land-based operations) satisfying a U.S. Department of Defense initiative to eliminate gasoline fuels for safety and logistic reasons. One key advantage of the Orbital technology is extended range; the improved fuel efficiency can increase the range on a typical mission by 40% over current technology, or can allow AAI to increase the payload.

Aircelle and Applied Composites Engineering expand services agreement

16-Apr-2012 17:25 GMT

The Safran group's Aircelle business unit signed an agreement to enlarge the scope of jet engine thrust reverser and nacelle repair and services performed by Applied Composites Engineering (ACE) in the U.S., building on three years of successful cooperation. This new agreement sets the framework to expand ACE's maintenance, repair, overhaul, and services activities for Aircelle with jet engines that power regional airlines and business jets in the Americas. It follows the work performed by ACE since early 2009 on Aircelle-manufactured thrust reversers on three regional airliners, for the following platforms: Embraer's ERJ 145, powered by AE 3007 jet engines; along with the Embraer 170 and 175, which are equipped with CF34 engines. During a three-year period, ACE has processed several hundred thrust reversers at its Indianapolis, IN, facility, demonstrating the company's capabilities to deliver high-quality, efficient, and on-time work.
