Several automakers have produced vehicles that can run on hydrogen fuel cells. Hydrogen fuel cells are able to provide vehicles with plenty of driving range and produce no harmful emissions that contribute to pollution. One of the biggest downsides to fuel cell powered vehicles is that the hydrogen-refueling infrastructure is basically nonexistent.

Two companies have announced a memorandum of understanding for marketing tri-generation stationary fuel cell power plants. The two companies include Air Products and FuelCell Energy. The two companies are working on market development to provide stationery Direct FuelCell power plants that are able to produce hydrogen, clean electricity, and usable heat.

The companies want to market these tri-generation stationary fuel cell power plants not only to industrial hydrogen users but for vehicle refueling applications. One significant feature of the system is that it produces not only hydrogen, but it also produces electricity and heat. The heat and electricity can be used to reduce the need for purchased electricity in the industrial setting.

In the vehicle fueling setting the electricity generated can be used by the fueling station and the heat could be used for climate control. These two companies are working together on a three-year-production project in California began in 2011. This particular project is providing renewable hydrogen for vehicle fueling along with clean electricity by converting biogas generated from waste water treatment process into renewable hydrogen.

The 24 hour race at Le Mans held every year is among the most punishing automotive tests on the planet: race-bred machines running top-speed (or close) for a full day. Recently, gasoline-powered cars have had their dominance usurped by diesels, who themselves are now losing to hybrids. The next step? It could be EVs. The GreenGT H2 will take the grid of next year’s 24 hour race as an experimental entry, driving the full race distance pushing only water vapor out its tailpipe. Hydrogen is stored in the two large tanks running down the sides, while the massive fuel cell stack itself is situated behind the driver. Power output is somewhere north of 500 horsepower, which is quite healthy for a car that the company hopes will be down under 1000Kg (2,200 pounds) by the time it hits the track in anger. Enough to win Le Mans? Almost certainly not, but it’ll be fun to watch it try.

Toyota will launch 21 new hybrids before the end of 2015 and an all-electric compact car, the Toyota eQ, in Japan and the US later this year, as part of a significant investment in eco-friendly transportation. The roll-out will start with a new 2.5-liter gas engine which, Toyota claims, achieves a world-record setting thermal efficiency of 38.5-percent, and be followed by a smaller capacity, turbocharged version, a Prius that can power your fridge in an emergency, and then a fuel-cell system in 2015.

“Thermal efficiency” is how much of the energy produced by fuel combustion actually gets converted to mechanical work, and is something traditional gasoline engines are particularly bad at. Toyota says its new 2.5-liter engine should appear in hybrids in 2013, followed by a 2.0-liter turbocharged version for even better efficiency in 2014.

Meanwhile, the existing Prius PHV plug-in hybrid which launched at the start of this year, will soon get an accessory that will allow the car to provide power to external devices in an emergency. The system will be positioned as a way to use the Prius PHV as a standby battery during power-cuts, though it’s unclear what limits there might be on what can be plugged in.

Toyota will also begin wireless battery charging trials in Toyota City come 2013, using wireless coils embedded in the road and in the chassis of the car, to see whether they’re efficient enough.

As for the Toyota eQ, the all-electric vehicle is based on Toyota’s gas-powered iQ city car, with seating for four and a range of up to 100km (62 miles) on a single charge of its new 12 kWh Li-Ion battery. The updated power pack delivers the best electric power consumption rate in the world, Toyota claims, keeping bulk low but still delivering usable range.

It also charges swiftly, the company says, with a complete rejuicing in around three hours from a 200V AC outlet. That extends to 8hrs if you’re stuck with a 100V AC connection, however, though a quick DC charge up to 80-percent can be achieved in just 15 minutes.

Toyota doesn’t talk speed or acceleration for the eQ, which doesn’t exactly bode well for urban racers, but the car isn’t really intended for consumer use. When it hits Japan in December it will be priced at 3,600,000 yen (the equivalent of $46,000 in the US, where it will launch as the “iQ EV”) and be targeted at fleet customers rather than individuals.

Finally, Toyota says it is on-track to launch its own fuel-cell vehicle around 2015, powering the FCV (“Fuel Cell Vehicle”) initially, and then showing up in a bus on track for a 2016 debut. The new fuel-cell has the world’s highest power output density, Toyota claims, and can deliver 3 kW/L which is double what the company’s current prototype can deliver.

That’s despite being half the size and half the weight of the existing prototype. It’s in part down to a new boost converter, which increases voltage and thus allows for fewer fuel-cells and a smaller motor: cost and bulk goes down, while performance goes up.

Recycling wastewater to generate energy has turned up noses before, but researchers at Oregon State University have developed a microbial fuel cell that can create 10 to 50, or even 100 times more electricity per volume than similar technologies. After refining the tech for several years using new materials, techniques and selecting better microbes, the team can now extract two kilowatts per cubic meter of refuse. As bacteria oxidizes organic matter, electrons — rather than the hydrogen or methane that other methods rely upon — are produced and run from an anode to a cathode within the device to create an electric current. Once implementation costs are cut down, the technology could power waste treatment plants and enable them to sell excess electricity. The contraption isn’t just for processing what comes out of the porcelain throne — it can also utilize materials ranging from grass straw to beer brewing byproducts. For now, however, the cell will tackle a pilot study before it inches closer to your local brewery or water treatment facility.

Hearing that fuel cells aren’t the most efficient thing in the world shouldn’t take you by surprise, but a determination by one Alfred Anderson just might. The chemistry professor from Case Western Reserve University is now making a case for using something other than platinum as the “catalyst most commonly used to convert chemical energy to electricity.” According to him: “Using platinum is like putting a resistor in the system.” To be fair, Anderson still isn’t sure which material should replace it, but he’s adamant that wizards in the field should be spending their time looking for substitutes instead of tweaking platinum further. Currently, he’s working with other researchers in order to find something that’ll one-up what we’re using today, and if you’re into oodles of technobabble, you can dig into the ins and outs of his claims in the source link below.
