US Army Base Goes Green With Renewable Energy Projec PDF Print E-mail

The U.S. military's biggest base on American soil has begun drawing nearly half of its power from renewable energy, days after President Donald Trump's decision to pull out of a global agreement to fight climate change.

Fort Hood, in Texas, has shifted away from fossil fuels to wind- and solar-generated energy in order to shield the base from its dependence on outside sources, a spokesman said.

"We need to be autonomous. If the unfortunate thing happened and we were under attack or someone attacked our power grid, you'd certainly want Fort Hood to be able to respond," Chris Haug, a spokesman for Fort Hood, said in a phone interview.

The project brings the Army base, home to 36,500 active-duty personnel and some 6,000 buildings, in line with the Department of Defense's decade-long effort to convert its fossil fuel-hungry operations to renewable power.

It comes in the wake of Trump's decision last week to withdraw the United States from a landmark global agreement to fight climate change, the Paris accord, a move that drew condemnation from world leaders and heads of industry.

The project is already fully operational. Its 63,000 solar panels, located on the base's grounds, and 21 off-base wind turbines provide a total of some 65 megawatts of power, according to an Army statement.

Previously, some 77 percent of base's energy was generated by fossil fuels, a 2015 draft report assessing the renewable energy plan shows.

Burning fossil fuel generates greenhouse gases that are blamed by scientists for warming the planet.

The Paris accord aims to reduce such emissions, including by encouraging a shift to clean energy.

Fort Hood's new solar field and wind farm will result in savings of more than $100 million over some 30 years, the Army said.

Over the last decade, the U.S. military and intelligence officials have developed a broad agreement about the security threats that climate change presents, in part by threatening to cause natural disasters in densely populated coastal areas, damage American military bases worldwide and open up new natural resources to global competition.

The number of military renewable energy projects nearly tripled to 1,390 between 2011 and 2015, a Reuters analysis of Department of Defense data previously showed.

The Defense Logistics Agency (DLA), a Department of Defense agency assisting the Army in its renewable-energy shift, is also working with the U.S. Air Force on long-term renewable energy projects, a DLA spokeswoman told the Thomson Reuters Foundation.

The Hydrogen Fuel-Cell Revolution Has Started PDF Print E-mail

The feasibility study called “Project Portal” will begin at the Port of Los Angeles this summer with the support of the California Air Resources Board (CARB) and the California Energy Commission (CEC). The CEC is investing in hydrogen fuel-cell infrastructure to support refueling needs while CARB follows the feasibility study to develop appropriate regulations and incentives to expand this market. The Los Angeles port is one of the largest stationary sources of pollution in the region and to reduce emissions in and around the ports, the 2017 Clean Air Action Plan (CAAP) proposes to gradually transition to zero-emission heavy commercial trucks by 2035. For the feasibility studies, a hydrogen fuel-cell truck from Toyota Motor North America will haul cargo between the port and warehouse facilities up to 70 miles away.

The concept’s gross combined weight capacity is 80,000 lb. and its estimated driving range is more than 200 miles per fill, under normal drayage operation. (Courtesy of Toyota


“Hydrogen fuel-cell vehicles play a role in California’s efforts to achieve greenhouse-gas emission-reduction goals, improve air quality, and reduce our reliance on fossil fuels,” says Janea A. Scott, commissioner of the California Energy Commission.  “That’s why the California Energy Commission is investing in the refueling infrastructure needed to support adoption of these vehicles. The Commission applauds Toyota for putting this cutting-edge technology to use in a heavy-duty freight proof of concept. This demo will show how fuel cells can help support the heavy-duty sector’s efforts to increase efficiency, transition to zero-emission technologies, and increase competitiveness.”

This technology has already been used as fuel for spaceships by NASA. Making it even more desirable and interesting is the fact that it is more efficient than diesel or gas. In addition, it has the potential to eliminate pollution caused by burning fossil fuels, reduce noise, and more. The technology must overcome disadvantages and challenges, too, such as the lack of hydrogen infrastructure. Planning for hydrogen infrastructure is very much needed, as it is so far an expensive power source solution. Also, fuel cells require water to be humidified to generate electricity. To ensure that vehicles operate under freezing conditions, vehicle designers needs to take this aspect into account.

According to Toyota, the truck was created using a Kenworth chassis. It generates more than 670 horsepower and 1,325 lb/ft. of torque from two Mirai fuel-cell stacks and a 12-kWh battery (a relatively small battery to support class 8 load operations). The Toyota Mirai was the first hydrogen fuel-cell vehicle to sell more than 200 units a year in the U.S.

“Toyota believes that hydrogen fuel-cell technology has tremendous potential to become the powertrain of the future,” says TMNA Executive Vice President Bob Carter. “From creating one of the world’s first mass-market fuel-cell vehicles, to introducing fuel-cell buses in Japan, Toyota is a leader in expanding the use of versatile and scalable zero-emission technology. With Project Portal, we’re proud to help explore the societal benefits of a true zero-emission heavy-duty truck platform.”

Kudos to studies like Toyota’s Project Portal for seeing a potential for the technology in California and opening the doors to zero-emission trucking.  Fuel-cell technology for trucks is not in commercial production yet. But projects like these are the first step toward building a business case for the consideration and adoption of new zero-emission technologies where clean-air goals are a major economic driver.

Saudis take 100% control of America's largest oil refinery PDF Print E-mail

America's largest oil refinery is now fully owned by Saudi Arabia.

Saudi Aramco, the kingdom's state-owned oil behemoth, took 100% control of the sprawling Port Arthur refinery in Texas on Monday, completing a deal that was first announced last year.

Port Arthur is considered the crown jewel of the US refinery system. The Gulf Coast facility can process 600,000 barrels of oil per day, making it the largest refinery in North America.

Aramco previously owned 50% of Port Arthur through a joint venture co-owned with Royal Dutch Shell (RDSA) called Motiva Enterprises.

But the two oil giants had a rocky relationship and reached a deal in March 2016 to separate their assets. Shell put out a statement on Monday confirming the "completion" of that break-up.

In addition to Port Arthur, Aramco is acquiring full ownership of 24 distribution terminals. Aramco also gets the exclusive right to sell Shell-branded gasoline and diesel in Georgia, North Carolina, South Carolina, Virginia, Maryland, the eastern half of Texas and the majority of Florida.

Aramco's deal allows the oil giant to shore up one of its best customers -- the US -- ahead of next year's planned IPO. Now that it controls the largest American refinery, Aramco can send more Saudi crude into the US for refining to sell to North American drivers.

Saudi Arabia is already America's second-largest source of crude, behind only Canada. The US imported 1.3 million barrels of Saudi crude a day in February, up 32% from last year, according to the Energy Information Administration.

Saudi Arabia is hoping the Aramco IPO will be valued at a stunning $2 trillion. The kingdom continues to grapple with low oil prices and a bloated budget, making it critical that the Aramco IPO goes off without a hitch. Saudi Arabia, the largest oil exporter in the world, dramatically slashed taxes on Aramco in March in an effort to quell concern about the oil giant's valuation.

Even as Saudi Arabia extends its reach in the US, the Trump administration has pushed for American energy independence by unleashing the domestic energy industry. Trump said in a May 2016 speech that he wants to bring about independence from "our foes and the oil cartels."

Trump also threatened before he was elected to halt imports of oil from Saudi Arabia and other Arab countries if they didn't commit ground troops to fight ISIS.

After Trump was elected, Saudi energy minister Khalid al-Falih later warned that blocking the kingdom's crude could backfire.

"Trump will see the benefits and I think the oil industry will also be advising him accordingly that blocking trade in any product is not healthy," Falih told the Financial Times in November.

Despite that rhetoric, relations between the US and Saudi Arabia appear to have improved under Trump. Saudi Arabia's powerful deputy crown prince Mohammed bin Salman met with Trump in the Oval Office in March, a meeting heralded by the kingdom as an "historic turning point" between the two countries.

Amazon gets huge stake in Plug Power under $600 million deal PDF Print E-mail

Amazon, the online retailer, has agreed to contract with Latham-based fuel cell manufacturer Plug Power that could  total $600 million and give Amazon a large stake in the companyPlug Power's stock was up 71 percent on the news, reaching $2.22 a share in afternoon trading Wednesday.

The deal, the biggest in Plug Power's history, would also mean $70 million in added revenue this year alone for Plug Power, a company that had $85.9 million in total revenue last year and has never turned profitable.

"This agreement is a tremendous opportunity for Plug Power to further innovate and grow while helping to support the work Amazon does to pick, pack and ship customer orders," Plug Power CEO Andy Marsh said in a statement. "Our hydrogen fuel cell technology, comprehensive service network, and commitment to providing cost savings for customers has enabled Plug Power to become a trusted partner to many in the industry and we are excited to begin working with Amazon."

Amazon will also work with Plug Power on its new line of fuel cell engines designed for cars and trucks.

Plug Power's main product right now is its GenDrive fuel cell used in fork lifts that operate in warehouses.

Plug Power said it started talks with Amazon a year ago and actually shipped GenDrive fuel cells to Amazon warehouse sites last fall.

Under the deal, which would give Plug Power $70 million in additional revenue this year alone, Amazon has been given warrants to purchase more than 55 million shares of Plug Power stock at $1.18 a share, although adjustments on the exercise price would be made over the life of the deal.

BlackRock was the single largest Plug Power shareholder with 9 million shares as of last April, a 5 percent stake. But Amazon could obtain a 23 percent stake if it exercises all of the warrants it can obtain.

The warrants would vest over time as Amazon spends $600 million on Plug Power's fuel cells over multiple years.

Amazon was granted 5.8 million stock warrants upon the signing of the deal. It would get another 7.2 million warrants after spending $50 million with Plug Power. 

That means that Amazon could become Plug Power's largest shareholder sometime this year, although the company is currently in the process of selling an additional $75 million in stock.

Chevrolet ZH2 Truck Brings Hydrogen Closer to the Battlefield PDF Print E-mail

April 3, 2017

The camouflaged military truck sped across the dirt and mud in near silence. The only noise was a low air-compressor whine and the crunch of tires through the rough terrain.

This futuristic pickup – a modified Chevrolet Colorado – runs on electricity generated by a hydrogen fuel cell. The zero-emissions truck is the result of a $4-million partnership between General Motors and the U.S. Army to determine whether hydrogen fuel cell vehicles are ready for the combat zone.

GM brought the truck, code-named ZH2, to its proving grounds in Milford, Mich., on a windy March afternoon to demonstrate the pickup’s capabilities.

The ZH2 will soon be delivered to the Army for testing. Hydrogen fuel cell vehicles have the potential to offer greater range, fuel efficiency and noise reduction than the diesel-powered trucks currently in use.

In this test, the off-road truck, based on the Colorado ZR2, demonstrated that it brings new-age efficiency and ample muscle to the front line. More than 1,000 pound-feet of torque provided brisk and consistent acceleration. Like the ZR2, it can scale soggy moguls and romp down steep descents with ease. Even at high speed over gravel and gopher holes, the ZH2 is stable and smooth.

“The vehicle can power through that, unimpeded by the terrain, and you’re doing it efficiently,” said Charlie Freese, director of GM Global Fuel Cell Activities. “We’re doing it with more than twice the efficiency of the internal combustion engine.”

The vehicle has four radiators, and various parts from Chevrolet’s Camaro and Corvette. Except for the stock Colorado doors, all body panels are made of carbon fiber infused with Kevlar.

The ZH2 has a top speed around 70 mph and peak range around 200 miles, but is capable of much more, Freese said.

GM used an older-generation fuel cell system in the ZH2 because it had proven capability in more than 3 million miles of testing. The company is currently working on systems that are smaller, quieter, more powerful and more affordable.

“This is already a stable system, so we know how it performs,” Freese said. “This one’s good. The next one’s fantastic.”

Reporting for Duty

Hydrogen “really provides flexibility and options because we can produce it from any number of ways,” said Brian Butrico, chief engineer at the U.S. Army Tank Automotive Research, Development and Engineering Center, or TARDEC.

Hydrogen can be produced from a variety of sources, such as natural gas and fossil fuels, or renewable energy such as wind and solar power.

The Army wants to learn if it can transition to hydrogen fuel from JP-8 – a form of diesel that powers tactical vehicles and generators.

It is enticed by the potential benefits of the ZH2 fuel cell system, Butrico said. Its only emission is water. In a pinch, it could provide water to soldiers at a rate of two gallons per hour. The Exportable Power Take-Off unit loaded in the truck bed can be removed and used as a mobile generator with 25 to 50 kW of power.

“That’ll run a subdivision,” Freese said.

The military has long been interested in hydrogen fuel cell technology. As far back as 1995, the Department of Defense deployed fuel cell vehicles around the world for testing. TARDEC ordered and tested a number of Ford Escape fuel cell vehicles for years in the late 2000s. GM is currently working with the U.S. Navy on an unmanned underwater vehicle powered by hydrogen fuel cells.

“It’s really evolved to be a vehicle that is quite impressive,” said Scott Samuelsen, director of the National Fuel Cell Research Center at the University of California, Irvine.

The ZH2 itself is not likely to make its way into military fleets. The Army, however, is serious about implementing hydrogen fuel cell technology on the battlefield as soon as possible, Butrico said.

The Army will take delivery of the ZH2 on April 10. The truck will spend several months at different bases around the country, each one providing new challenges and testing scenarios. After one year, the military will evaluate the tests and decide how to proceed.

“If there’s one thing our guys are good at, it’s breaking stuff,” said Doug Halleaux, a TARDEC spokesman.

How the ZH2 responds to Army testing will determine the next steps.

“Really it’s what do the soldiers think about it?” Butrico said.

Finally Time to Shine?

Hydrogen fuel cell vehicles also are starting to show up in the civilian light vehicle market. Automakers are investing heavily in technology as they work to meet increasingly stringent emissions standards.

In California, the Hyundai Tucson, Toyota Mirai and Honda FCX Clarity hydrogen fuel cell electric vehicles are already on public roads.

A 2014 report by research firm Frost & Sullivan predicts that nine automakers will produce hydrogen fuel cell vehicles by 2020. General Motors has logged more than 3 million miles of testing its own hydrogen fuel cell vehicles and is partnered with Honda on further development

Nick Loris, analyst at the Heritage Foundation, has in the past been skeptical of government investment in alternative fuels. The Department of Defense has been mandated to spend public money on renewable energy for political reasons, Loris said. But if the military now sees a practical purpose for hydrogen fuel cells, that’s different, he said.

“If it makes sense for the military and Department of Defense to invest in alternative fuels and it increases their operational readiness, or increases their capabilities and improves their missions, then that makes all the sense in the world,” Loris said.

“The more we can rely on the private sector for those things; you’re not creating a market out of thin air. You already have the developed technology, so that’s certainly an added benefit.”

Butrico said he can see hydrogen fuel cell technology in military vehicles within the next five years. He said hydrogen fuel cells could feasibly provide supplemental power to even a 30-ton Bradley tank.

But the first step, he said, is the ZH2.
