Hydrogen Fuel Cells and Alternative Fuels

Hydrogen Fuel Cells and Alternative Fuels

I recently had the privilege of speaking to members of the New York State Chapter of the American Public Works Association (APWA) during their annual conference in Canandaigua NY.

The discussion was on Alternative Fuels and I spoke on the future of Alternative Fuels regarding how it will affect Public Works Fleets and Operations.

The attendees were very knowledgeable and very interested in the how the alternative fuels are likely to impact their operations.

The images shown are of General Motors Equinox Hydrogen Fuel Cell Vehicle

This fuel cell vehicle operates on compressed hydrogen gas that when fueled with hydrogen derived from electrolysis powered by non-fossil fuels is a true zero emissions vehicle. It is truly amazing to drive this vehicle and even when following it you can actually see that the emissions are water vapor.

While we are a long way from having cost competitive hydrogen available at the local gas station, this is a practical, vehicle that can be driven without any special training and the only unusual consideration is in making sure you know where the next fuel station is located.

Monroe County (Rochester) NY is at the forefront of making alternative fuels into mainstream products. They have recently completed a new state of the art fueling center that provides gasoline, gasohol (E20 and E85), diesel (biodiesel blends from B5 through B20), CNG, and Hydrogen all in a modern, efficient, and safe Green Fueling Station.

Monroe County and its forward thinking team lead by County Executive Maggie Brooks who have not only acknowledged the future, but have embraced it. They have recognized that there is a lot Federal, State, and private money available to municipal governments that are willing to lead the way into a greener future.

They are benefiting from grants for infrastructure, equipment, and even free or low cost vehicles. They are able to take advantage of research initiatives by elite universities and world class manufacturers who are providing testing resources that would be virtually unobtainable outside of governmental involvement.
This proactive approach has benefited not only Monroe County, but will provide long term benefits to the private sector in the region surrounding their operations.

We strongly believe that this type of public leadership will directly translate into benefits for the taxpayers and residents both now and in the future.

I want to thank Dave Butters, John Graham (retired), and Bob Hamilton of Monroe County for providing me with the opportunity of speaking to this auspicious group.

OPEC and the Price of Oil – March 15, 2009

OPEC and the Price of Oil – March 15, 2009

OPEC, at its meeting Sunday (March 15, 2009) in Vienna decided not to ask members to cut output any further. This decision will hold off any official changes until the next meeting in May.

As is normal for this group of market manipulators, they cannot agree on what to do or how to do it, so they create a press release that tries to convince the not too bright, that they are maintaining production levels to “help” with the worlds current economic problems.

Nothing could be further from reality or the truth. They did not cut production for a host of reasons, first and foremost is that many of their members are ignoring the previous reduction of 2.2 million barrels per day that supposedly took effect in December. Even by their numbers (which are far too generous) they are only getting 80% compliance from their members on those production limits.

Why you may ask are they unable to control production and force up prices? Well the biggest issue is that many of these OPEC Countries (Note: OPEC Countries theoretically control about 40% of the world’s oil) spend their petro-dollars as fast or even faster than they take them in. Venezuela needs oil to be about US$80.00 per barrel just to pay the bills.

Many of the Middle Eastern countries have gone on staggering spending sprees basically acting as socialist entities.

These countries temporarily import workers to do their dirty work, while their own citizens do less and less but keep getting ever growing government handouts to live on (this sounds vaguely like some western country I may have heard of).

They have spent hundreds of billions on infrastructure projects and other enticements to try and bring foreign businesses to their countries before the oil runs out (yes, it will run out).

However all of this has been based on cheap capital and the idea that oil would keep going up in price forever.

Well fast forward to today, There is more crude oil sitting in storage than at any time in history, the demand is off by more than 1 million barrels per day (Note: this is another manipulated number and the reality is that demand is off by two or even three times this number), the economy in the US and now the rest of the industrialized world is contracting and will likely do so for a year or more, before starting a slow, painful, and just plain ugly recovery, and it appears that there is at least a glimmer of hope that the world including the US will finally wake up and recognize that the way we have been using energy for the last 100 years is unsustainable and that we need to do things now, not is 20 years to fix the problems.

All of this leads me to some oversimplified conclusions on oil pricing over the next year or two. If there is reduced economic activity worldwide there will be less demand for oil. The oil inventories will likely continue to grow as OPEC and Russia will need to pump more and more to make up for the lower per barrel prices.

Right now there is a concerted effort to hold and try to push crude prices up. However to keep oil in storage costs a lot of money every day. At some point traders and speculators will decide that they cannot afford to pay $100,000.00 a day to park crude in a tanker because the price is not going up enough make it profitable. When this happens, we could see oil flood the markets at levels not seen since the 1970’s. This will then further exacerbate the problems of the oil producing countries who will try to pump even more.

Short of a war (not out of the question) or a cataclysmic natural disaster, it is hard to see crude oil going up significantly anytime soon.

Refiners and some marketers are likely to benefit as crude prices decline and more finished product becomes available. In some areas where there is tightly controlled distribution there may months or even years of high profitability due to reduction in cost followed more slowly by reduction in retail prices.

I have regrettably spent my life creating a carbon footprint of embarrassing proportions. I am now working on reducing not only my negative impact on the world, but on creating new and better ways for everyone to do the same without destroying their livelihoods or lifestyles.

Clean Coal – An Oxymoron or a Real Possibility?

Clean Coal – An Oxymoron or a Real Possibility?

Can coal be clean? We have all heard the condescending advertising, listened to the biased politicians, and been overwhelmed with huge amounts of conflicting “expert” opinion and research data from each side.

Let’s start with the basics, “What is coal?” Coal is a sedimentary rock made up mostly of carbon, with varying amounts of sulfur, oxygen, hydrogen, nitrogen, and lesser amounts of many contaminants including mercury and other poisonous compounds.

We believe coal is primarily made up of plant material that has partially degraded, compressed and through this pressure and with time and other geologic forces been transformed into the many forms of what we refer to as coal. Some of these forms are Peat, Lignite, Bituminous, Anthracite, and Graphite.

The process of photosynthesis converts carbon dioxide into carbon, the conversion of the dead plant matter into coal sequesters the carbon in the ground. If we look at this in a very big picture sense, coal is the energy of the sun converted and stored. When the coal is burned, that carbon is released in the form of carbon dioxide. This could be a manageable cycle, however what is happening today, is that millions of years worth of this stored sunlight bound up in the form of carbon is being released in a relatively short period of time. This rapid release has overloaded the systems (the worldwide environments) ability to convert the carbon dioxide back into some stored form.

What can we do about this problem? First we must burn (or otherwise convert) this coal as cleanly and efficiently as possible. Large scale coal gasification and burning to create electricity will create fewer more easily managed source of pollution. These very large sources can be more easily forced to the use technology needed to clean the exhaust stream coming from such a facility.

Next we need to develop ways to reuse or store the Carbon Dioxide (CO2). There are ideas that would pump this material back into the earth either as part of oil pumping operations or into decommissioned mines.

I believe that we need to consider alternatives that would use some significant part of this CO2 to grow Algae as part of a closed loop energy system (See previous article on the Richards Cycle) or some other photosynthetic process that would convert the CO2 back into a safe storable (or reusable) form.

Coal can also be converted into high quality liquid fuel s (gasoline and diesel) through several processes. If we can create a more earth-friendly method of doing this, we could significantly reduce our dependence on and need for imported oil.

While this is not a permanent solution, it would definitely give us a cushion while we develop alternative energy forms and strategies.

Whether or not Coal can ever be Clean, I don’t know. What I am certain of is that we can develop much cleaner, safer, and eco-friendly methods to mine and use this high quality domestic energy source.

Biodiesel Cold Soak Filterability - ASTM D6751 Annex A1

New ASTM Biodiesel Test Specification for Cold Weather Operability

The American Society for Testing of Materials has recently added a new test requirement to the D6751 Biodiesel Specification.

This new requirement is referred to as ASTM 6217 or as Annex A1 of ASTM D6751– Cold Soak Filterability.

Cold Soak Filtration Analysis is defined as: The time in seconds that it takes for cold soaked biodiesel to pass through two 0.8 micron filters and the amount of particulate matter expressed in milligrams per liter (mg/l) collected on the filter.

What does this mean? When biodiesel is stored in temperatures below 40°F for extended periods of time, certain components will precipitate (fall) out of solution and fall to the bottom of the storage tank. This precipitate will build in a thickening layer at or near the tank bottom. In general the colder the temperature and the longer the biodiesel stays at a given temperature, the more material will fall out.

This material can very quickly plug filters and shut down engines, usually at the worst time.

What is this material? It can have to do with the feedstock from which the biodiesel is created. Certain feedstocks, particularly Used Cooking Oils (UCO), Waste Vegetable Oil (WVO), and Animal Fats (Tallow) will produce high levels of precipitate. The material can also be due to incomplete removal of glycerin during the transestrification process.

This new test is a positive step in making biodiesel a more consistent user friendly product.

Natural Gas as a Transportation Fuel – A Cautionary Note

Natural Gas as a Transportation Fuel – A Cautionary Note

Natural Gas is currently being promoted as a domestic clean, safe, and cheaper alternative to petroleum fuels.


Some thoughts for your consideration.


Natural Gas as domestic source of energy. The US currently imports approximately 16% of its natural gas. Some comes to us by pipeline and some in the form of LNG via ship. Increasing the use of natural gas to replace petroleum fuels simply shifts our imports from one product to another.


Currently the US uses approximately 22% of our natural gas to create electricity. This is a poor use of a valuable resource for a need that has many other fuel sources available. If this was replaced by wind, solar, nuclear, and a future renewable bio-source (see previous article: The Richards Cycle) you could eliminate our imports.


Natural Gas as a clean motor fuel. Compressed Natural Gas (CNG) and Liquefied Natural Gas (LNG) both reduce certain emissions however they are not as clean as some would have us believe. If you look the whole basket of emissions that come out of the exhaust on an internal combustion engine, a 2010 Selective Catalytic Reduction (SCR) Diesel engine actually is less polluting than an equivalent CNG or LNG engine.


While I believe you can safely use CNG and LNG, it requires more training and much greater diligence on the part of drivers and operators vehicles and fueling stations. It is important to remember that it can take far longer to fuel LNG and particularly CNG fueled equipment. This long fueling cycle can lead to lack of attention and added expense in fueling equipment.


Natural Gas as cheaper alternative. Many people incorrectly try to compare a gallon of diesel to a gallon of LNG or a gallon of CNG. While the price per gallon of the LNG and CNG may appear to be cheaper, you need to consider the energy in the gallon. For example a gallon of diesel contains approximately 139,000 Btu’s of energy, while a gallon of LNG contains about 73,500 Btu’s, and CNG works to about 34,750. In short it takes about 4 times the space to store an equivalent amount of CNG as compared to diesel.


The other concerns with vehicles powered by CNG or LNG are that they are far more expensive to purchase, for example a school bus built to run on CNG can be $30,000.00 to $40,000.00 more than its diesel counterpart.



Also when you purchase a vehicle powered by CNG or LNG you locked into one supplier for all fuel system and some engine components for ever. There is virtually no secondary supplier compatibility. You limit the range and usefulness of the vehicle due to limited ability to refuel that vehicle away from its domicile. Lastly, you have to be concerned about the value of those vehicles when it comes time to trade or sell them. In many cases this limited resale market can make a used vehicle worthless.


There is an important and growing place for alternative fuel vehicles and equipment. It takes visionary leaders with long term commitment and very deep pockets to make a change to this type of equipment successful.

E-Diesel – A Fuel for the Future?

E-Diesel – A Fuel for the Future?

Image Courtesy of University Of Illinois

E-Diesel is a blend of Ethanol and Diesel Fuel together with a multifunctional additive package. E-diesel is typically a 7% to 15 % blend of Ethanol in #2 diesel fuel together with 2% to 5% of additive. Early on it was referred to as “Oxygenated Diesel”, now however; most call it E-Diesel.

E-diesel is popular in Brazil as they produce a large amount of Ethanol from biomass left over from growing and processing sugar cane. Brazil has a limited supply of domestic crude oil and this has given them a huge incentive to develop alternative fuels and their government has stepped up to the plate to make it happen.

As a result Brazil is today an energy independent country, something we should aspire to become.

E-diesel has not been popular in the US, although it has been tested in some large fleets here with mixed results.

However the problems with Ultra-Low Sulfur Diesel, with Biodiesel being forced into our diesel and the recent very high price of fuel (now temporarily better) have made this technology worth another look.

E-diesel has a number of negative characteristics, it is hygroscopic (soaking up huge amounts of water if allowed to do so), Ethanol lowers the flash point of the diesel, Ethanol destroys lubricity in the fuel, and Ethanol makes the fuel less stable.

The pluses are that it improves cold weather characteristics, lowers CO and NOx, potentially (when derived from cellulosic biomass) lowers cost of the finished fuel, and increases the amount of non-petroleum renewable fuel available.

E-diesel using Ethanol produced from Bagass (the parts leftover from making sugar from sugar cane) is winner. Ethanol made from corn is a loser, the yield is very low, and it affects human and animal feedstocks.

The biggest winner is if you make diesel fuel from algae and use the biomass left over to produce Cellulosic Ethanol which can be burned in boiler, added to gasoline, or added to diesel. It is possible that Ethanol produced in this manner could cost as little as $1.00 per gallon.

The potential of producing a high quality cellulosic Ethanol from biomass is a game changer.

Ethanol in fuels presents significant problems in many areas. However these problems can be overcome or managed through changes in the way we handle fuels and blending, changes in equipment using these fuels, and though the use of properly formulated additive packages.

Parking Crude Oil

Parking Crude Oil

Here is a bit of information that is hard to digest.


Speculators are leasing Super Tankers called Very Large Crude Carriers (VLCC’s) (tankers holding 2 million barrels or 84,000,000 gallons each.) to store crude oil. There are currently between 35 and 45 of these behemoths sitting, many in the Gulf of Mexico and Persian Gulf holding approximately 80,000,000 (80 million) barrels or 3,360,000,000 (3.36 billion) gallons of crude.


This is almost one day’s worldwide consumption. The speculators are and have been paying $60,000.00 to $75,000.00 dollars per day to lease each of these tankers to sit holding this oil.


Factoid: If you lined 35 VLCC tankers end to end, the total length would be about 7 miles.


Why would someone pay this huge amount of money to park oil in the ocean? Well look at it this way, using the $60,000.00 per day figure to store 2,000,000 gallons of crude works out to approximately $.03 (three cents) per barrel per day. If it sits there 100 days that’s only $3.00 per barrel.


Now let’s say that you purchased crude that was $35.00 per barrel and today (02/26/2009) it is $45.00 per barrel. Even if you have stored it for 100 days at $3.00 per barrel or $6,000,000.00 ($60,000 X 100 days) you will still profit $7.00 per barrel or $14,000,000.00.


So this might us to conclude that the current rise in crude oil prices is a manipulation of the market rather than the result of supply and demand.
Right now the market is off by about 1,000,000 barrels per day, there are at least 80,000,000 barrels floating around, every land storage tank in the world is full, all waiting for the price to go up.


OPEC would have us believe they are reducing production to stabilize (this means “drive up”) the price of crude oil. In reality they are reducing production only because they have no where left to put it.


In a true supply and demand world, prices should be going down, not up.

One thought is that our government should be filling the national Strategic Petroleum Reserve (SPR) as fast as they can get it in the ground. If all of these speculators believe crude will go up in the future then this a worthwhile investment to make.


In spite of the fact the current price is based on market manipulation, I doubt that the government will ever be able to police it. The ability to move staggering amounts of oil around the world with little or no regulation or accountability makes tracing it virtually impossible.The best things we can do are to reduce consumption through more efficient vehicles, equipment and practices and to work on alternative fuels to reach a point where we are able to produce most if not all of our fuel domestically.
