New Simplified Calculation Procedure for Levelized Cost of Energy (LCOE) and Feed-in Tariff

As part of the on-going technical preparations for the proposed mini-conference on the Mindanao Power Crisis this coming late August or early September 2010 and the main conference on “Energy & Climate Change”, the workshop coordinator, Mr. Marcial T. Ocampo, has prepared the simplified calculation procedure for calculating the levelized cost of energy (LCOE) and levelized selling price (tariff) for conventional and renewable energy resources.

The result of the simplified formulas using the US NREL formula for generation cost and the RP MTO formula for selling price were compared with the results from a full-blown project finance model and the variance between the two methods were minimal in most of the power generation technologies analyzed.

The input data came from the IEPR research summary of 2007 and from internationally published data on power generation technology by noted experts such as Paul Breeze and yours truly, Marcial Ocampo. More »

Available Project Finance Models with CDM and Renewable Energy Law Incentives

I just finished polishing all my project finance models for the following power generation technologies and are now available for actual runs by project developers, researchers and individuals doing business development.  Using the models below will allow user to determine as quickly as possible the “best new entrant” technology applicable to a particular location given the fuel and energy resource available and the electricity tariff prevailing in the area.

Fuel Cells

The file (566 KB) will cover the following topics:

FUEL CELLS

Fuel Cell: an electrochemical device, closely related to the battery, that can generate electricity from hydrogen, which in turn can be extracted from natural gas or other hydrocarbon gases through a chemical process called reforming.

Topics – Fuel Cells

  • Fuel Cells, Its Uses and History
  • Fuel Cell Principle, Characteristics, Operating Conditions
  • Fuel Cell Concept for Power, Heat & Water
  • Balance of Plant Equipment
  • Fuel Cell Process Diagram, Hydrogen Gas Reformation
  • Types of Fuel Cells (AFC, PAFC, PEM, MCFC, SOFC)
  • Advanced Fuel Cell Technologies (CHP, Hybrid FC-GT-IGCC)
  • Cost of Fuel Cells
  • Fuel Cell Applications, Advantages
  • Environmental Impact & Risks

History of Fuel Cel

  • Hydrolysis – if an electrical voltage is applied to water by placing two electrodes into the liquid and attaching a battery to them, the voltage induces a chemical reaction: hydrogen is produced at one electrode and oxygen at the other
  • 1839 – Sir William Grove observed that the process known as “hydrolysis” can also go backwards – hydrogen will react at one electrode and oxygen at the other producing water and an electrical voltage between the electrodes. It was only a century later that Francis Bacon began to develop practical fuel cells.
  • 1950s – Pratt and Whitney (now United Technologies) licensed Bacon’s technology and developed it for the US space program. The Gemini, Apollo and space shuttle program all used fuel cells to generate electricity and produce drinking water on-board by just bringing hydrogen fuel and oxygen with them.

Fuel Cell Principle

  • If an electrical voltage is applied on water, by placing two electrodes into the liquid and attaching a DC battery to them, the voltage induces a chemical reaction; hydrogen and oxygen is produced at each electrode:

H2O + DC voltage è H2 + O2

  • In 1839, Sir William Grove observed this process, known as hydrolysis, can also go backwards – reversible. Hydrogen will react at one electrode and oxygen at the other, producing water and DC electrical voltage between the electrodes.
  • During reverse hydrolysis, hydrogen would act at one electrode and oxygen at the other, producing water, heat and electrical voltage (DC) between the electrodes.

Fuel (H2) + O2 + platinum catalyst è H20 + DC voltage

Fuel Cell Characteristics

  • Operates as a continuous battery – continuous fueling
  • Never needs recharging
  • Based on reverse hydrolysis – converts hydrogen and oxygen into water and electricity
  • Current depends on electrode area
  • Voltage depends on materials of construction, typically less than 1 volt.

Balance of Plant Equipment

  • Power-conditioning equipment needed are expensive
  • Fuel processing comprises a large part of cost and project development.
  • The front-end processing and fuel cell technology is affected by the fuel and application: Hydrogen, Natural gas, Methanol, Gasoline, Biomass, Coal
