There are many fairy tales about LNG!

Fuel composition is really important in the LNG fuel chain.

There are standards for fuel grade LNG for transportation.

There are already many applications worldwide.

With fuel grade renewable bio-LNG, we can skip fossil LNG and have sustainable

transportation today.

We can clean the air with bio-LNG!

What is natural gas?

3

There are as many different types of natural gas as there are gas fields.

Every gas field has its own specifications, differences in Wobbe index, calorific value, density, methane number, amount of inertia (i.e. nitrogen, carbon dioxide) and percentage of heavy hydrocarbons like ethane, propane and butane.

Examples:• Natural gas with high percentage of ethane and propane has high density, low methane number, high Wobbe index, and high calorific value per cubic meter.• Natural gas with a large amount of nitrogen has high density, (also) low methane number, but low Wobbe index and low calorific value per cubic meter. • Ethane and propane provide more energy per liter but less per kilogramme.

Entry specifications for the grid in several countries. HHV = high heating value = 35,1 for Groningen gas

KBR, Natural Gas Specification

Challenges in the LNG Industry.

“A [CNG] fuel containing a high inert gas component inevitably leads to limitations

in achievable mean pressure. At the rated power point, a power loss of up to 30% is expected compared with [high calorific gas], whereas a reduction of up to 11% may occur at the maximum torque operating point. However, it must be pointed out that the cited figures apply to an engine optimally tuned to [high calorific gas]. If the engine is tuned to a low calorific gas or a less knock resistant natural gas, the negative impacts of changes in gas quality on full-load response can be avoided or at least significantly diminished. However, it must be considered that the potential of [high calorific gas] that is already widespread in Europe may not be exploited to the full.”

Why calorific value is important for transportation

LNG differs in composition

LNG, liquid natural gas, consists for the largest part of methane, which is liquid at a temperature of minus 162 degrees Celsius.

LNG is made from natural gas all over the world. All CO2, H2S, particles, mercury have to be removed. Water freezes out.

Depending on the source, the composition of LNG still varies. Methane content is between 88% and 99.9%.

Essentially we consider two types of LNG:• Rich LNG contains a relative large quantity of heavy hydrocarbons• Lean LNG contains few (no) heavy hydrocarbons.

Compositions of LNG from large liquefaction plants

'Market opportunities for Small Scale LNG' WTC-Rotterdam, 15

december 2010

Of 17 large LNG liquefaction plants in 2003 only one (Alaska) produced lean LNG and the others produced rich LNG (methane 89-91%, ethane/propane 9-11%).

LNG carriers sail on boil-off. During 20 days of transport boil-off can be over 2%. As boil-off is evaporated methane, increase of heavy hydrocarbons concentration means that the calorific value per cubic meter LNG can increase by 0.2-0.3 Megajoule and decrease the same amount per kilo.

Boil-off during transportation by LNG carriers changes the composition and quality of the LNG

POSITION PAPER BY CIMAC WORKING GROUP ‘GAS ENGINES, INFORMATION ABOUT THE USE OF LNG AS ENGINE FUEL, DECEMBER 2008

“natural boil-off gas” which is taken off the top of the LNG tanks above the liquid will have a high methane content and some nitrogen and thus have a

high knocking resistance. Analysis show values typically around MN 100 and LCV between 33 – 35MJ/nm3. (Initial gas extraction after up-loading may have reduced calorific value because of the high nitrogen content at the top of the tanks). This is a somewhat special application typical for fuelling of LNG tanker propulsion plants. “forced boil-off gas” i.e. LNG extracted from down in the tanks and evaporated separately. This gas will contain a mixture of all hydrocarbons in the liquid and

its resistance to knocking may differ from origin to origin and even from load to load, with the MN typically in the range between 70 and 80. The calorific value will be higher than natural boil-off gas and quite stable at around 38 – 39 MJ/nm3.

LNG 50.000 liter(-160 graden)

Storage of 50.000 liters LNG with 8 % C2/C3. Boil-off 0,1% /day, storage empty after 10 days.

250 liters of methane lost.

Boil-off 0,1%/day, after 100 days, storage half empty. 3750 liters of methane lost.

Composition of remaining LNG 9,2% C2/C3.

Boil-off at LNG fuelling station also changes composition

But there is more:

Boil-off in Large and Small-scale LNG Chains (NTNU 2008):“In this study it was calculated that for a 50 cubic metres LNG tank, which

thermal conductance is estimated to be 2 W/K, the total fuel loss is about 7% of the total filled fuel, when fuelling four buses every day. The fuel loss decreases to less than 3% and less than 1%, when fuelling more than ten and more than thirty one buses every day. It is evident that the total fuel loss strongly depends on number of buses fuelled each day.”

Resource Guide for Heavy-Duty LNG Vehicles, Infrastructure, and Support Operations (U.S.A. 2002):“The potential exists for heavy gases to build up in the fuel within a storage container over time, reducing the methane content of the fuel. This fuel can

cause reduced engine performance and even engine failure when used on a vehicle.”

And beware of change in quality because it can harm your engine and can give security problems.

Don’t use oversized storage tanks for small fleets

REVITALIZE YOUR LNG ASSET(S)MAKE VEHICLE FUEL GRADE LNG

“Fuel Grade LNG is:• Is of consistent composition, similar to diesel or gasoline, that provides consistent engine performance.• Is of consistent composition for commercial transactions.• Public LNG dispensers can be checked by the local Weights and Measures authority.”

“Fuel Grade LNG is:• Methane ≥ 97.0 Mole %• Ethane ≤ 1.0 Mole %• Total Inert gases ≤ 2.0 Mole %”

After CHI ENGINEERING SERVICES, INC.Chris Hosford, P.E., President

“Vehicles fueled by the transportation grade LNG produce approximately one-sixth of the nitrous oxides (NOx) and up to 15 percent less greenhouse gases than comparable petroleum diesel fueled vehicles.”

Experience in countries like USA, Australia, China, Japan etc. shows that fuel grade LNG can be provided by peak shavers and small scale LNG liquefaction plants from stranded gas, dedicated gas fields or pipeline gas).

But it still will be fossil fuel, that is why we promote renewable bio-LNG from our own waste with a low carbon footprint.

Like other transportation fuels, there is a need for an international fuel grade or vehicle grade LNG

What is bio-LNG (LBG, LBM)?

15

Bio-LNG is produced from biogas. Biogas is produced by anaerobic digestion.

All organic waste can rot and can produce biogas, the bacteria do the work. Therefore biogas is the cheapest and cleanest biofuel without competition with food or land use.

Bio-LNG (LBM, LBG) = liquid bio-methane. Quality is always better than quality of fossil LNG, so no problems with >99% of methane.

How to produce Bio-LNG?

The carbon footprint of bio-LNG from waste from your own country is of course much better than the footprint of fossil LNG from far across the Oceans.

The process from natural gas to LNG costs more process energy and investment than the upgading and liquefaction of biogas to bio-LNG.

Bio-LNG gives the highest CO2 reduction of all fuels and no dust or NOx.

Bio-LNG: the new diesel, available now!

We can deliver bio-LNG today from the UK, in 2012 Dutch bio-LNG will be available.

Costs of bio-LNG will not be higher than fossil diesel, so you save the climate and your money.

Recommendations

• Set a worldwide standard for LNG as a transportation fuel, like was done for all other transportation fuels.• Start with small fuel stations for trucks and avoid boil off / aging.• Start with small scale LNG plants for bunkering facilities.• Avoid methane losses in the entire chain.• Combine LNG with pure CNG in one station.• ASAP shift to bio-LNG (and bio-CNG from bio-LNG).• Any region can have its own independent bio-LNG chain from waste.

Note that bio-LNG is produced from rotting biomass. Using feedstock which produces methane in nature, we avoid greenhouse gas emissions by controlled anaerobic digestion and liquefaction to bio-LNG.
