SEMINARIO SOBRE BALANCE DE ENERGIA Y EFICIENCIA ENERGETICA
Ing. Marcelo Jaramillo C.Marzo 2011
BALANCE ENERGETICO
OBJETIVO DEL SEMINARIO:CONCEPTOS GENERALES:DEFINICION DE ENERGIACONCEPTO DE FUENTES Y USOS DE ENERGIAFUENTES: CLASIFICACION, CARACTERISTICASUSOS: CLASIFICACIONBALANCE ENERGETICO: CONCEPTO, EJEMPLOSEFICIENCIA ENERGETICA
BALANCE ENERGETICO Vs MATRIZ ENERGETICA
• BALANCE ENERGETICO: Contabilización de la Oferta y la Demanda de energía y sus procesos, en un sitio y periodo definidos.
• MATRIZ ENERGETICA: Cuantifica la interrelación entre Oferta energética, su inventario, sus procesos de transformación y la Demanda, detallando su evolución
APLICACIONES
Definir Inventarios, tasa de aplicación y usos
Priorizar aplicación de recursos según su naturaleza
Optimizar el uso de energéticos
Optimizar los procesos de Transformación
Optimizar los procesos de uso
Propender a la EFICIENCIA ENERGETICA
ANTECEDENTES
• Incremento de la población
• Industrialización y Desarrollo
• Consumo de energéticos no-renovables
• Contaminación Ambiental
Clasificación de ENERGIAS
• ENERGIA PRIMARIA• PROCESOS ENERGETICOS (ENERGIA EN
PROCESO):• ENERGIA SECUNDARIA• ENERGIA FINAL• ENERGIA UTIL• EFICIENCIA ENERGETICA
PLANTEAMIENTO
• DEFINIR LAS FUENTES DE ENERGIA Y SUS CARACTERISTICAS EN RELACION CON LAS NECESIDADES DE LA DEMANDA
• IDENTIFICAR LOS PRINCIPIOS FISICOS APLICABLES A LA GENERACION Y TRANSFORMACION DE LA ENERGIA

Technology-based Solutions:There is no single nor simple answer
• Energy efficiency• Renewable energy• Non-polluting transportation fuels • Separation and capture of CO2 from fossil fuels• Next generation of nuclear fission and fusion technology• Transition to smart, resilient, distributed energy systems coupled with
pollution-free energy carriers, e.g. hydrogen and electricity
PreviewGrand energy challenge
- double demand by 2050, triple demand by 2100
Sunlight is a singular energy resource- capacity, environmental impact, geo-political security
Breakthrough research directions for mature solar energy- solar electric- solar fuels- solar thermal

Means of Producing Ethanol from Biomass & other Wastes
Thermochemical Hydrolysis
Technology Pros Cons Technology Pros Cons
Gasification – Catalytic Lower capital cost, feedstock flexibility, high yield per ton of feed
Tar production, requires gas cleanup, catalyst poisoning, catalyst disposal, production of mixture of low alcohols (I.e., impure product)
Dilute Acid Hydrolysis Low capital cost, low acid consumption, public domain technology
Lower conversion efficiency, co-factor/toxin production
Gasification – Bioreactor Lower capital cost,feedstock flexibility, high yield per ton of feed
Tar production, requires gas cleanup - bioreactor poisoning with real feedstocks.
Strong Acid Hydrolysis Medium-high capital cost, low acid consumption
Low conversion efficiency, co-factor production
Fractionization - Mechanical
Recovery of pure components
Moderate capital cost, high energy cost
Concentrated Acid Hydrolysis
98% recycling of acid, high conversion efficiency, near zero liquid discharge
Moderately-high capital cost
Fractionization – Solvents
Recovery of pure components
Moderate capital cost, high energy cost
Enzymatic Hydrolysis Enzyme cost reduced recently
NOT Suitable for MSW and Green wastes
Hybrid – Dilute Acid/Enzymatic Hydrolysis
Enzyme cost reduced recently
Co-factor production
Potential Cellulose-to-Ethanol Technologies Initially Reviewed by ARK Energy, Inc.
– Enzymatic Hydrolysis - uses enzymes to cleave the “carbon-oxygen-carbon” link in cellulose molecule
– Acid Hydrolysis - uses acidic protons (H+) to cleave the “carbon-oxygen-carbon” link in cellulose molecule
• Strong, or Weak acid (i.e., concentrated, or dilute)
• Sulfuric, Hydrochloric, Nitric, Hydrofluoric, and so on.– Combination of acid/enzymatic hydrolysis
Structure of the cellulose molecule
Site of attack by enzymes OR acid
Conclusions• Concentrated Sulfuric Acid Route MORE CHEMICALLY EFFICIENT and
MORE THERMALLY EFFICIENT than either Dilute or Weak Acid Routes.• Concentrated Acid Reconcentration Technology is ALREADY IN INDUSTRIAL
USE throughout the world. Safety record is ESTABLISHED.• Concentrated Acid Hydrolysis produces NO TOXINS OR COFACTORS to
inhibit fermentation. • Dilute and Weak Acid Hydrolysis Routes DO PRODUCE TOXINS AND
COFACTORS to inhibit fermentation.• Concentrated Acid Hydrolysis Technology is ECONOMICAL.• Concentrated Acid Hydrolysis Technology is PROTECTED BY PATENTS.

La reducción de las emisiones de CO2 en algunos países europeos
Las opciones tecnológicas de largo plazo
producción de hidrógeno y / o de electricidad a partir de los recursos fósiles (carbón) con captura y almacenamiento de CO2
producción de combustibles y de carburantes a partir de la biomasa
producción de electricidad a partir de las energías renovables (fotovoltaica, solar termodinamica, geotermia profunda)
Las nuevas ramas de actividad nucleares (EPR)
Transportes: grandes proyectos de infraestructura y vehículos limpios : soluciones híbridas
Construcción: certificación de la calidad energética de las construcciones y reglamentación térmica (referencial)
Análisis del impacto de calefacción eléctrica/climatización sobre el consumo eléctrico de punta (impactos fuertes en términos de emisiones de CO2)
Empresas: cuotas de emisión de CO2 y Permiso de emisión: versus un mercado nacional / internacional (certificados CO2)
El dominio de la energía: un preámbulo necesario
Las restricciones económicas ligadas al desarrollo de las energías renovables
Peso de lass inversiones: electrificación rural, producción de electricidad a partir de las EnR (hidroelectricidad, eólica, geotermia)operadores: compañias nacionales de electricidad, productores independientes, delegación del servicio público (régimen de la concesión
Herramientas promotoras nacionales o internacionales: tarifa de compra de la electricidad (negociadas, bajo licitación pública), financiamientos internacionales (GEF), utilización de los mecanismos CDM (complicado), fondos de garantía o fondos de inversión (con derechos CO2)
Cuadro legislativo: estatuto de la producción independiente, régimen de la concesión, PPA, fiscalización (amortización) …..
