Template for Levelized Cost of Energy, Project Finance Model and Power Plant Emission Calculation
This December 2010, your energy technology selection and business development consultant/expert is providing his avid readers and fans a very good bargain.
Marcial is going to offer low cost templates for various power generation technologies to determine electricity tariff and for renewable energy the feed-in tariff.
He will also offer power plant emission calculation models which the user may modify given the actual fuel properties and chemical analysis.
So hurry up. This is a limited offer. Email me right now to avail of the huge discount on the template models that are user friendly and could be user modified. More »
Advanced Electric Vehicle Concept – Hydrogen powered fuel cell hybrid vehicle
Congratulations to US Pres. Obama for giving importance to the electric vehicles (EVs) since this will be the precursor of the ultimate vehicle – the hydrogen-powered fuel cell hybrid electric vehicle. Hydrogen can be produced from many energy pathways, including off-peak renewable energy and nuclear energy as well as from biomass, biogas, municipal solid waste, by-product of chemical processes such as coking of steel, and the traditional steam reforming of fossil fuels such as gasoline, diesel, LPG, natural gas or LNG and coal. As the world gradually shifts from the present high carbon economy, to a lower carbon economy, then hydrogen economy, followed by a rebirth of nuclear energy, and finally breeder nuclear economy, to provide mankind’s future energy into the 22nd century.

How to use biomass for energy and power
Here is my reply to an avid reader requesting for advice on how to use biomass effectively in his home town.
How to Lower Power Plant Emissions – some suggestions
Here are my simple suggestions on how to lower power plant emissions and address global warming and climate change issues.
I am not an environmental scientist, but this I can say.
As long as your liquid fuel has lower than 1% Sulfur by weight, you will not exceed SO2 concentration (in volume % or parts per million by volume or as mg/Nm3 or milligram per normal cubic meter) required by the EPA (usually given in ppm and mg/Nm3 for both old and new power plants).
Having sufficient excess air (3-15% or average of 9%) will help eliminate unburnt fuel emission such as CO (carbon monoxide) and THC (total hydro carbon) as well as unburnt carbon (C) particles.
You also need to lower impurities such as ash to reduce total suspended solids (TSP) emissions (ash and unburnt carbon fuel).
To lower NOx emissions, the firing of oil must be done in stages so that the flame is not too hot that it will dissociate nitrogen (N2) in the air into oxides of nitrogen (NOx) that contributes totogether with oxides of sulfur (SOx).
But this days, you have to address global warming and climate change issues by lowering your carbon (C) or as (CO2) emissions. This means keeping the fuel to electricity conversion efficiency (thermal efficiency) as high as possible, which is typically around 33-36% for oil based on the steam Rankin cycle. To lower the carbon footprint, you need to move away from the simple steam Rankin cycle to combined cycles (CCGT) to raise efficiency to over 54-59%, almost double, thus reducing the carbon footprint by almost half.
Hope I was of help,
For the readers who would want to design a power plant that addresses global warming and climate change issues, energy efficiency considerations, cost of power plant and resulting electricity tariff, please email me your concerns as I may provide you a good feasibility study that addresses all the above issues.

Sample Power Plant Emission Question and Solution
Here is an email from a reader:
Thanks for the reply, but I am not a mathematician. I am just trying to get a general idea of output. Any ideas how much two boilers that burn about 6,000 gallons per hour of #2 oil release?
Greatly appreciate- Jeff
