Eden Energy Reports Successful Testing of Naturally-Aspirated 6L Hydrogen-Methane Engine for India Bus Fleet; Turbo Version Under Development

Australia-based Eden Energy Limited has successfully tested a production-ready 6-liter engine that will enable India’s largest bus manufacturer, Ashok Leyland, to power buses with Eden’s low-emission Hythane blend of hydrogen-enriched natural gas (usually 20% hydrogen by volume). (Earlier post.)

The 6-cylinder 92 kW (123 hp) 2010 H06B CNG engine—developed by Ashok Leyland in conjunction with Eden’s wholly-owned US subsidiary,

Hythane Company—was initially designed to meet the country’s current Bharat IV (Euro IV) mandatory emissions targets. However, the results from the calibrated control system and exhaust catalyst testing for the naturally-aspirated engine would meet Bharat V (Euro V) requirements, according to Justin Fulton, Hythane Company’s Director of Engine and Fuel Systems.

Over the “European Transient Cycle” (ETC), an engine dynamometer test that simulates real-world driving conditions for heavy-duty vehicles, the Hythane engine tests yielded the following improvements relative to the natural gas baseline:

  • NOx emissions reduced by 16.6%
  • Total hydrocarbon (THC) emissions reduced by 15.1%, including a non-methane

    hydrocarbon (NMHC) reduction of 66.6%

  • Carbon dioxide (CO2) emissions reduced by 6.2%
  • Fuel efficiency improvement of 6.5% based on fuel combustion energy.

Eden Energy will receive royalties from both Ashok Leyland and the engine control system provider for all Hythane-fuelled-engine sales.

In the near future, Ashok Leyland will also release turbo-charged versions of the H06 engine, and the control system strategies used for these engines will allow them to take advantage of hydrogen’s combustion properties above and beyond the improvements seen in the base CNG/Hythane engine.

Preliminary investigations on the new engines began in April after the base engine production calibration work, and production-intent optimization by Hythane Company and Ashok Leyland will continue this year.

India joined the International Partnership for the Hydrogen Economy (IPHE) as a founding member in 2003. By 2006, a National Hydrogen Energy Roadmap was created to plan for a transition to hydrogen energy and infrastructure, including power generation and transport applications. The Roadmap’s Vision 2020, through the Green Initiatives for Transport (GIFT), calls for 1 million vehicles to be operating on hydrogen fuels by 2020. (Earlier post.)

The release of India’s first production Hythane engine will precede the country’s first large-scale refuelling station for hydrogen-enriched natural gas, as previously announced by Eden Energy. This station, due to be constructed by the end of the year, will refuel 50 to 70 buses in Mumbai.

In addition to the Ashok Leyland buses, another major Indian bus manufacturer has approved in principle a development project to recalibrate their engines for optimized Hythane fuel operation in 2010, according to Eden Energy.

Finnish and Russian Companies Partner to Develop and Build Specialty Icebreaker to Combat Oil Spills

The Finnish companies STX Finland Oy, Aker Arctic Technology Oy, Southeast Trading Oy (SET Group), and the Russian companies OAO Sovcomflot and FSUE Rosmorport have signed a cooperation agreement for the purpose of developing and building a new generation of icebreaking and rescue vessel for oil spill combat in the Gulf of Finland under ice conditions.

The new type of vessel represents a breakthrough in the icebreaking technology, according to the partners. Furthermore, this will represent a big step forward in strengthening the Finnish-Russian cooperation in the field of shipbuilding.

The multipurpose vessel, featuring an asymmetrical hull that is based on the icebreaking technology developed by Aker Arctic Technology Oy, will be able to use an innovative sideways movement to collect the oil in demanding ice conditions, as well as to break a broad ice band effectively.

The vessel will also be able independently to solve support, escorting and towing tasks for large tankers in the Baltic Sea. The vessel—about 67 meters long and about 19 metres wide—will be equipped with three rudder propeller devices, and will also be able to tackle a wide range of other towing and rescue tasks.

STX Finland Oy is a shipbuilding company that specializes in building special-purpose icebreaking and ice-class vessels and has a long history of cooperation with the Russian maritime industry. The company’s shipyards have during the last century delivered approximately 2,500 ships to Russia / Soviet Union.

Much to the joy of environmentalists, in its first week the new coalition government in the UK announced that the third runway at Heathrow Airport was being cancelled.

Last autumn, unaware of this twist of fate, Greenpeace held an architectural competition asking architects to design an impregnable fortress to block the runway. Despite the fact that it won’t be buil… Read the full story on TreeHugger

Steve McCallion writes a remarkable series in Fast Company asking “Why has Memorial Day, like so many of our national holidays, been reduced to appliance sales, fast food specials, and vacation deals?” He starts with Reinventing Memorial Day: Beyond the Mattress Blowout Sale :

In this era of convenience and instant gratification–when mobile screens hold more interest than parades; when regulations are needed to prevent texting while driving; when TV idols are created in the time it takes to si…

On Fareed Zakaria’s CNN show, GPS, Bill Gates gave a gloomy answer when asked about the prospects of the U.S. creating renewable energy projects at such a large scale that they will replace dirty fuel sources like coal and oil in the coming decade. Gates, normally sanguine on the power of technology and market forces to cause transformative change at a rapid pace, said that the technology to store energy f…

In January I visited Toronto’s Urban Mode for the opening of their new Blu Dot showroom, which I thought was very attractive. What I didn’t know until I was researching the new Sustain Trio MiniHome was that it was a green prefab! Blu Dot co-founder Charlie Lazor would be so proud. I visited it this weekend to catch some pictures.
