    Tiny microalgae could lead to hydrogen economy

    Tiny microalgae could lead to hydrogen economy

    This is an interesting development. Hydrogen fuel made this way could be pollution free.

    Despite skepticism from some quarters, it appears the hydrogen economy is beginning to take shape with accelerating speed. In the latest news, a research team at Tel Aviv University developed a way to speed up the rate of algal hydrogen production by about 400 percent.

    The news is significant because it provides another pathway for producing hydrogen from renewable sources that are far more sustainable than the current source of choice, natural gas.


    The path to renewable hydrogen

    From a tailpipe perspective, hydrogen is an attractive fuel because it produces no emissions when used in a fuel cell. Fuel cells generate electricity by combining hydrogen with oxygen, and the only byproduct is water.

    Scientists find efficient way to turn CO2 into ethanol

    It seems to be a cheap and easy to make fuel source. And it turns CO2 into ethanol.

    This process has several advantages when compared to other methods of converting CO2 into fuel. The reaction uses common materials like copper and carbon, and it converts the CO2 into ethanol, which is already widely used as a fuel.

    Perhaps most importantly, it works at room temperature, which means that it can be started and stopped easily and with little energy cost. This means that this conversion process could be used as temporary energy storage during a lull in renewable energy generation, smoothing out fluctuations in a renewable energy grid.

    Hydrogen train set to begin operations in Germany...

    First zero-emission hydrogen train to begin operations in Germany
    Friday 4th November, 2016 - Germany will put the world's first hydrogen-powered zero-emission train into service in 2017; The non-electric network trains are powered using a hydrogen fuel cell and only emit steam and water
    The world's first hydrogen powered, emission-free train is set to go into service in Germany in 2017 -- a ground-breaking innovation that could signal the phasing out of heavily polluting, diesel-powered trains. The first "hydrail", or hydrogen-powered train, will begin transporting passengers on the Buxtehude-Bremervörde-Bremerhaven-Cuxhaven line in Lower Saxony, in northern Germany, in December 2017, German newspaper Die Welt reported.


    The world's first hydrogen-powered emission-free train, the Coradia iLint from Alstom, is set to go into service in Germany at the end of 2017.

    Although the first train in operation will only run a short, 60-mile (96-kilometer) route, four German states have signed an agreement with Alstom, the French company that builds the trains, for the purchase of up to 60 additional locomotives, if they are judged a success. "Alstom is proud to launch a breakthrough innovation in the field of clean transportation," Alstom chairman and CEO, Henri Poupart-Lafarge, said in a statement. "It shows our ability to work in close collaboration with our customers and develop a train in only two years."

    Quiet revolution

    The new, silent train, called the Coradia iLint, was unveiled by Alstom at a railway industry trade fair in Berlin earlier this year, and only emits steam and condensed water. Although not suitable for electric railway lines, it's designed to provide a clean alternative to the large number of heavily polluting diesel trains that run on non-electric lines throughout Europe.
    Germany alone has more than 4,000 diesel-powered train cars, according to Alstom, and about 20% of all of Europe's current rail traffic is hauled by diesel locomotives according to the European Union. The train uses the same equipment as a diesel train but runs on an entirely new technology that uses hydrogen -- a waste product of the chemical industry -- as the fuel source. Energy to power the train is generated by large fuel cells that sits on top of the train. This cell combines hydrogen with oxygen to produce electricity, which is then stored in batteries.


    Visitors check out the Coradia iLint train after it was unveiled at Innotrans, the railway industry's largest trade fair, in Berlin

    Each two-car train-set requires a fuel cell and a 207 pound (94kg) tank of hydrogen to supply it, while the oxygen is obtained from the local air. The train can complete a 500 mile (800 kilometer) journey on a full tank of hydrogen, which is enough for one day according to Alstom, and carries up to 300 passengers. Although the 87 miles per hour (140 kilometers per hour) speed the train reaches is far below that of other European trains, such as the German Inter-city Express and French TGV, it is well suited to the quieter and shorter stretches of the European rail network that haven't yet been converted to electricity. Initial tests on the two pre-production trains that were unveiled at the trade show will be completed by the end of the year, according to Alstom. The two units will then undergo further testing throughout 2017, prior to their expected approval for operation by Germany's Federal Railway Office at the end of that year.

    It would be nice if they are viable. The European train system is amazing, but the electrical lines all over are an eye sore.

    Toyota’s hydrogen fuel cell trucks are now moving goods around the Port of LA...

    Toyota’s hydrogen fuel cell trucks are now moving goods around the Port of LA
    Oct 12, 2017 - The only emission is water vapor
    A concept version of Toyota’s hydrogen fuel cell truck is running short-haul drayage routes at the Port of Los Angeles as part of a feasibility study, which figures in to the port’s efforts to reduce harmful emissions. The truck will move goods from select Port of LA and Long Beach terminals to surrounding rail yards and warehouses for distribution. Toyota estimates the vehicle’s daily trips will total around 200 miles — short, frequent route patterns designed to test the duty-cycle capabilities of the fuel cell system. As the study progresses, longer haul routes will be introduced.

    Toyota unveiled its plan to build a fleet of heavy-duty, zero-emission, hydrogen fuel cell trucks last April. The concept truck generates more than 670 horsepower and 1,325 pound-feet of torque from two Mirai fuel cell stacks and a 12kWh battery. Its gross combined weight capacity is 80,000 pounds. Hydrogen fuel cells — which use compressed hydrogen as their fuel and release only water vapor as an emission — have been in development for decades, but only recently have they attained performance and range numbers good enough to replace an average driver's gasoline-powered car.

    That said, hydrogen hasn’t taken off as a propulsion technology due to severe shortage in fueling stations. Experts predict that commercial vehicles, like trucks and forklifts, could benefit more from hydrogen, thanks to access to centralized, industrial fueling stations at ports or warehouses. Toyota has more experience with fuel cell vehicles than most automakers. The automaker began selling its hydrogen-powered Mirai sedan in the US in 2015, but recent reports suggest the company has only sold several hundred units. Toyota has said it plans to sell buses powered by hydrogen fuel cells in Tokyo this year, in time for the 2020 Summer Olympics.

    And Toyota isn’t alone in pursuing zero-emission big rigs. Nikola Motor Company recently unveiled a huge class 8 truck that's powered by hydrogen fuel cells. The Salt Lake City-based startup claims its H2-powered truck will have an operational range of as much as 1,200 miles when it's released in 2020. Meanwhile, Elon Musk, who has called hydrogen power “incredibly dumb,” “extremely silly,” “mind-bogglingly stupid,” and most succinctly, “bull$#@!,” will be unveiling an electric battery-powered semi truck in November.

    Granny don't want Uncle Ferd to get a hydrogen car an' blow hisself up...

    Cars Powered by New Fuel Type Tested in AustraliaAugust 11, 2018 — Australian scientists have test driven two cars powered by a carbon-free fuel derived from ammonia. A team from the Australian government’s research agency, the CSIRO (Commonwealth Scientific and Industrial Research Organization), says the pioneering technology will allow highly flammable hydrogen to be safely transported in the form of ammonia and used as a widely available fuel.
    Researchers have found a way to use a thin membrane to turn Australian-made hydrogen into ammonia. This could be shipped safely to markets in Asia, as well as parts of Europe. At its destination, the liquid ammonia would then be converted back into hydrogen, and used to power cars and buses, as well as for electricity generation and industrial processes. David Harris, CSIRO research director says “the special thing about the technology that we have is that it allows you to produce very pure hydrogen directly with a membrane system from ammonia.” The technology has the support of Japanese car maker Toyota and South Korea’s Hyundai Motor Company.


    ‘Watershed moment’


    Scientists say hydrogen, a highly-flammable gas that can be volatile and hard to transport safely, creates a low emission fuel for cars. The Australian team describes the membrane technology that separates hydrogen from other gases as a “watershed moment for energy.” Claire Johnson, the chief executive of Hydrogen Mobility Australia, an industry association, says the pioneering research could forever change the transport sector. “We see that as a really exciting opportunity to decarbonize the transport sector, but also position Australia as one of the lead suppliers of hydrogen around the world. There is some competition to play that role, however. Norway, Brunei and Saudi Arabia have all flagged that they wish to be an exporter of hydrogen around the world.”



    A Toyota Mirai fuel cell vehicle is shown ready to be fueled with CSIRO-produced hydrogen.



    There are only a handful of hydrogen-powered cars in Australia, but there are tens of thousands across Japan, South Korea and Singapore. The South Korean government has recently announced plans for 16,000 more hydrogen-fueled cars and 310 special refilling stations.
