Pioneering hydrogen-powered building receives wind turbine
2008.12.08.
"One of the UK's first buildings to be powered by its own hydrogen received delivery of its wind turbine on Friday."
The Environmental Energy Technology Centre in
Rotherham,
Yorkshire, will use a Vestas V29 turbine to generate hydrogen from
January, which will then be used to power the building.
The turbine delivered on Friday is second-hand, being re-used after being replaced by a newer model at a wind farm at Newton Aycliffe, County Durham.Delivery of the 30-metre turbine took place late on Friday evening to avoid disrupting traffic on the busy A1 motorway, using two separate trailers for the tower as well as the 29m diameter blades and the hub.The second-hand turbine is rated at 225kW, capable of producing about 500MWh of power each year, equivalent to the needs of 100 homes.
Energy consultancy TNEI, which is working with the Pure Energy Centre to develop the "Hydrogen Mini-Grid" project on behalf of regional development agency Yorkshire Forward, said the V29 was ideal for low wind speeds.It will work with a state of the art high pressure alkaline electrolyser to turn the wind-sourced electricity into hydrogen, which will be stored under pressure for use as a transport fuel and to power the building during periods of low wind speeds or high power demand.

SUSTAINABLE HYDROGEN ENERGY PROJECT (SHEP)
2008.11.04.
The Sparhawk Mill is a four story brick building in Yarmouth, Maine which sits on the eastern bank of the Royal River (historically known as the Royall River). A dam spans the river just above the mill and provides low-head water to three 1984 Hydrolec turbines in the sub-basement, one of which is variable up to 90kW; the other two are fixed at 90kW. Presently the site generates around 900,000 kWh per year but slows to a nearly complete halt in July and August. It runs at irregular rates at other times throughout the year.
Based at the Sparhawk Mill and still in the conceptual stages, SHEP is a plan to make hydrogen (H2) from the dam's hydro-electric power and from off-peak renewable and standard power supplied through the power grid. The making of H2 is accomplished by device called an electrolyzer which yields H2 and oxygen (O2) from water and electricity. The H2 and O2 will be stored on-site. We then plan to make electricity for the newly renovated office complex in the mill and also for on-peak sales of electricity to the grid. Producing electricity from H2 is accomplished by a device called a fuel cell with water and heat as by-products. Both processes, making H2 and O2 from electricity & water and making electricity from H2 will each give off extra heat. We plan to use this waste heat to supply heat and cooling for the office complex. Finally, we plan to sell gaseous O2 for medical use and gaseous H2 for transportation and other industrial uses. We will also use a small amount of the H2 made at SHEP for public demonstrations of hydrogen as an energy carrier. We view this project as a technology incubator which may attract funding and participation from a variety of sources, including regional educational institutions, government, foundations, corporations, and individuals.
The Hydrogen Energy Center expects that, through SHEP, we can show how hydrogen, made from a mix of renewable (some delivered through the grid, some made from hydro on-site) and standard off-peak power, provides an environmentally positive step toward clean energy for an evolving power infrastructure. Using power from the dam and from other "green" sources delivered through the grid, we plan to provide a constant power source by using an electroyzer, hydrogen storage, and fuel cells to re-generate electricity from the stored hydrogen, all on site.
In the Sparhawk Mill, we are fortunate to have an interested and knowledgeable future landlord who wants very much to see this project work. It remains to be seen if the project can turn a profit by selling on-peak electric power, hydronic heat, hydrogen and oxygen while meeting operating expenses such as: buying off-peak electric power, rental of space, costs of operating and maintaining the facility. It is expected that in this initial demonstration project, we will operate at a loss. We hope that information gleaned from this project and an evolving market for hydrogen will show potential for and point the way to sustainable profit.

Hydrail - Hydrogen Railway Trains
2008.01.22.
Hydrail is a term used to describe the new breed of hydrogen railway trains. Much focus has been given lately to hydrogen cars and other vehicles, but little light has been shown on the emerging hydrail field. Hydrogen trains pack the promise of clean propulsion, fewer emissions and less dependency upon foreign oil.
 Hydrogen Train |
The old west may have been a time of coal-burning, black smoke chugging locomotives and more recent times have seen diesel-powered trains chugging their own share of fumes. But recent developments in hydrogen fuel cell technology have made hydrail more than just a pipe dream.
Hydrail is especially attractive for applications such as mining trains, and for railway systems at factories and military bases. The military is especially interested in hydrail since hydrogen fuel cell trains can serve as backup power generators on military bases.
The U. S., Japan and Denmark are all interested in hydrail technology. A company called Vehicle Projects out of Golden Colorado is credited with developing the first hydrogen fuel cell train. The 17-kilowatt, 3.6-metric-ton hydrogen-powered mining train, powered by Nuvera fuel cells was demonstrated in a working mine in 2002. Charlotte, North Carolina has also expressed interest in a hydrogen railway system replacing its current freight line, which connects to Mooresville 30 miles away.
Japan has enlisted a couple of different companies to compete for the honors of that countries first hydrogen train railway system. The target date is the summer of 2007. Denmark wants to be the first country in Europe to roll out a hydrogen train as well. Denmark's target date is 2010 to have a 35-mile stretch go hydrail between three cities in Western Jutland.
The First International Hydrail Conference was held in Charlotte, NC in 2005 and in 2006, the second conference was held in Herning, Denmark.
One of the most compelling arguments for adopting hydrogen trains rapidly is that a vast hydrogen distribution network will not have to be built anywhere near the scale that it will have to be built for hydrogen cars. The decreased mobility of a train as compared to a car will be an advantage in delivering hydrogen to just a few key refueling points along the rail line. Trains don't drive off-road or in complicated city streets and alleys like cars do, so this is an inherent advantage of hydrail.
It's true that hydrogen trains are not quite here yet, but the future looks bright. So bright in fact, that the light you see at the end of the tunnel, may one day just be a hydrogen train. And, that my friend, is a fact.

East Japan Railway New Energy Train
2007.03.12.
JR East (East Japan Railway), the largest locomotive company in Japan serving over 16 million commuters daily has demonstrated the world's first hydrogen hybrid commuter train. JR East's New Energy Train (NE Train) will replace current diesel and electric trains that run to remote locations where there are no overhead power cables.
 JR East New Energy Train |
Set to rollout commercially in the second quarter of 2007, the New Energy Train is powered by two 65kw polymer electrolyte membrane (PEM) fuel cells and a high-tech battery pack. The top speed for the JR East New Energy Train is 60 mph and its range is approximately 60 miles before refueling.
The New Energy Train also uses regenerative braking, similar to that used by the Toyota Prius and other hybrid cars in order to restore energy and recharge the lithium-ion battery pack. The New Energy Train also consumes 20-percent less fuel than traditional diesel locomotives.

With this hydrail demonstration, East Japan Railway has taken the lead on Tokyo's Railway Technical Research Institute (RTRI) who has also been competing to complete Japan's first hydrogen commuter train as well. The New Energy Train is noticeably quieter than its diesel counterpart powerful enough utilizing two 95kw electric drive motors.
