GM Looks to Hawaii for Hydrogen Infrastructure Pilot

Collaboration with The Gas Company Plans Stations on Oahu for Fuel Cells

New Pilot Program to Create Fuel Cell Stations in Hawaii

DETROIT and HONOLULU– Abundant hydrogen is available on the island of Oahu to power a ramp up of fuel cell vehicles through a General Motors collaboration with The Gas Company (TGC), Hawaii’s major gas energy provider, the two companies announced Tuesday.

TGC produces hydrogen along with synthetic natural gas and delivers it in its utility gas stream, with more than 5 percent hydrogen content today. Through a proprietary separation process, TGC plans to tap into its 1,000-mile utility pipeline system at key locations and separate the hydrogen for use by local fueling stations for fuel cell vehicles.

“This is the type of enabler that a hydrogen transportation infrastructure needs because it addresses both the source of the hydrogen and a feasible way to deliver it for fuel cell vehicle use,” said Charles Freese, executive director of GM Global Fuel Cell Activities. “The Hawaii infrastructure could eventually support tens of thousands of fuel cell vehicles.

Hawaii is uniquely positioned and motivated to make hydrogen-powered fuel cell transportation a reality because it depends on imported petroleum for 90 percent of its energy,” he said.

The state is committed to reducing petroleum use by 70 percent through a combination of renewable energy resources, conservation and efficiency. The use of hydrogen as a transportation fuel could be a key contributor.

“We have been delivering as much as 12 percent hydrogen made from renewable sources to our gas customers over the last two to three years and expect we can deliver even greater quantities of hydrogen as demand increases,” said Jeffrey Kissel, president and CEO of TGC. “By delivering hydrogen through our existing infrastructure as vehicle fuel wherever we have gas, The Gas Company expands its key role of supporting Hawaii’s clean energy future.”

Depending how the pricing for the hydrogen is set, it could be available at the equivalent price of gasoline or less.

GM, which has invested more than $1.5 billion in fuel cell transportation in the last 15 years, is developing a production-intent fuel cell system that could be ready for commercialization in 2015. Current Chevrolet Fuel Cell vehicles are part of Project Driveway, the world’s largest demonstration of fuel cell vehicles, which has amassed nearly 1.4 million miles of real-world driving by thousands of people since 2007.

U.S. Senator Dan Inouye, D-Hawaii, said he supports the pilot project.

“My small role was one of introduction between these two companies, not that many months ago, which resulted in this business announcement today,” Inouye said.  ”It is an important step forward in the establishment of a hydrogen transportation infrastructure upon which new fleets, both military and civilian, can be tested and utilized.  I am committed to support the resourcing of this endeavor.

“Every step to reduce our dependency on foreign oil is a move forward,” he said.

The GM-TGC collaboration is the leading edge of a broad consortium of federal and state, non-profit and education organizations that is forming to develop a Hawaii Hydrogen Initiative as part of an integrated energy solution for Hawaii’s future.

Cummins Demonstrates Solid Oxide Fuel Cell Auxiliary Power System

MINNEAPOLIS - Cummins (NYSE: CMI) successfully demonstrated a tubular solid oxide fuel cell (SOFC) in a hybrid-configured auxiliary power unit (APU) configured to power a Class 7/8 truck’s “hotel loads” while running on commercial ultra-low sulfur diesel (ULSD) fuel. The Cummins APU incorporated hybrid power electronics, system controls, and balance-of-plant components combined with SOFC modules supplied by Protonex Technology Corporation (LSE: AIM: PTX and PTXU).

The SOFC power unit was integrated with a modified power electronics section derived from Cummins Power Generation’s Hybrid Quiet Diesel™ (HQD) recreational vehicle power system. The hybrid power electronics provide dynamic load sharing between the SOFC and a battery pack.

The testing replicated the ten-hour rest period that is part of the daily routine of a typical over-the-road truck. Specific achievements demonstrated were:

· Operation on “straight from the pump” ULSD fuel during the entire test

· Operating a truck cab’s air conditioner and lighting solely from the SOFC sub-system power

· Hybridization of APU for instant-on capability and increased peak loading capacity-up to 3,800W AC available from the combination of fuel cell and battery boost

· Combined heat and power (CHP) generation

· Recharging batteries from the SOFC sub-system

· 1,260W net peak demonstrated DC power

· 940W net peak demonstrated AC power

· Average net power produced over test period: 1,100W DC or 820W AC

This demonstration, held at Cummins Power Generation facilities in Minneapolis, leveraged development supported by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE). The APU combines Cummins Power Generation’s HQD hybrid power electronics, controls and systems integration expertise with Protonex’ SOFC technology to address increasingly stringent anti-idling requirements aimed at reducing commercial truck emissions, noise and fuel consumption.

The HQD architecture-which can combine power from an engine-driven generator or fuel cell and a battery pack to supply AC and DC loads-potentially provides a versatile platform for a wide range of power system applications such as recreational vehicles, consumer marine, commercial mobile, truck APUs, and off-grid power for telecom or remote residences.

The SOFC APU system form factor and mission capabilities are comparable to commercially available diesel engine-based APU generators, highlighting the ability of the SOFC APU to be integrated into the same form factor as existing production hardware.

The hybrid-configured APU provides both AC power and DC power to the truck’s hotel loads. It intelligently controls charging of the energy storage system by regulating the power output of the SOFC sub-system and dynamically distributing loads between the fuel cell and stored energy. The SOFC sub-system efficiently converts chemical energy in the ULSD fuel directly into useful electrical power.

The inherent efficiency and nature of the SOFC reduces the carbon footprint and dramatically limits harmful emissions. This technology shows the potential to provide truck operators with a viable method to eliminate main-engine idling during rest periods. This demonstration of SOFC technology points the way toward significant fuel savings, while virtually eliminating noise and exhaust emissions. It also represents a significant step forward in Cummins’ evaluation of SOFC technology for possible future products.

“This demonstration marks a real milestone in Cummins’ experience: an integrated SOFC power system-in a package consistent with conventional technology-operating on the main engine fuel without supplemental water that’s capable of supporting a real-world mission of providing heating, cooling, and electrical convenience to a Class 7/8 truck sleeper,” said Dan Norrick, manager, Advanced Development, Cummins Power Generation.

“This is a testament to the feasibility of tubular-based SOFC systems in real-world applications. The cycling stability and robustness of the tubular architecture, combined with the inherent ability of SOFCs to operate on hydrocarbon-based fuels, makes it an ideal candidate for APU systems of this nature,” stated Dr. Caine Finnerty, vice president, SOFC Operations, Protonex Technology Corporation.

Decreasing Costs for Hydrogen Fuel Cells by 80 Percent

Scientists decrypt the action mechanism of highly-active noble metal catalysts.

The decryption of the action mechanism of a new catalyst can reduce the amount of platinum and hence the costs for hydrogen fuel cells by over 80 percent.

The researchers produced spherical catalysts with a diameter of only a few nanometres by mixing platinum particles with copper. In a following segregation process, the copper was partly removed which lead to the formation of a platinum shell having a thickness of only few atoms. Due to the mixing and segregation processes, the distance between the platinum-atoms at the surface is much smaller compared to conventional platinum.

This unnatural compressive stress of the structure of the top atom layer leads to a reduced binding strength of the oxygen atoms. Thus, these new platinum alloys become better catalysts for hydrogen fuel cells because the total rate of formation of water and therefore the electric wiring is much higher.

Using this method, the structural stress and hence, the activity of the catalysts can be changed continuously which results in an optimisation of the catalysts. Similar structural changes might be even possible for other noble metals and reduce costs, for example of water electrolysers.

Hydrogen-powered fuel cells represent a “green” alternative to conventional diesel and gasoline engines since their operation only produces electrical energy and water. The biggest challenge in the development of  hydrogen fuel cells is the reduction of material expenses. There are still considerable amounts of the expensive noble metal platinum neccessary to transform hydrogen and atmospheric oxygen into electricity and water rapidly enough.
