Climate neutral gaseous and liquid energy carriers
|
GAVE is a government programme that supports the development and introduction of climate-neutral fuels in the Dutch transport sector. The programme's most important task is to support the implementation of the European Renewable Energy Directive into Dutch national legislation with respect to biofuels. This EU Directive states that, by the year 2020, 10% of the energy used in the transport sector must be derived from renewable energy.

IEA develops roadmap for bioenergy
Date published: May 30, 2012 |
At the World Bioenergy 2012 conference, on May 29, the International Energy Agency (IEA) presented its new roadmap for bioenergy. The IEA expects bioenergy to make an important contribution towards the ever-increasing global demand for electricity and heat. To continue meeting demand, the agency expects a doubling of the necessary bioenergy supply by 2050.
By that time, 100 exajoules will be needed, equivalent to 5 to 7 billion tons of dry biomass.
The biomass will mainly come from decomposing plant and animal matter. The biomass will be obtained sustainably by 2050, and will mainly consist of wood, agricultural crops, municipal organic waste, and manure.
At present, 10% of global primary energy is of biological origin. The vast majority is used inefficiently, mainly for cooking and heating in developing countries. The IEA roadmap proposes therefore a target of having 320 million households in developing countries connected to advanced cooking stoves and biogas plants by 2030.
Moreover, in 2050, 20% of the heat for buildings worldwide must be generated from renewable biomass.
The IEA expects the strongest growth in use to come from the energy sector. Biomass must generate around 3,000 terawatt hours (TWh) of electricity in 2050. This is ten times the 270 TWh generated in 2010.
The roadmap also provides insight regarding the amount of avoided CO2 emissions. The goal is to emit around 2 gigatons less in CO2 equivalents per year. This is a reduction of 35% with respect to the business-as-usual scenario. Japan emitted this amount in 2009.
The IEA believes it is important to have good global agreements regarding the social and economic circumstances in which this growth will occur. A harmonised market needs to be developed, without disturbances or trade barriers, and including a reliable certification system.
The goals will not be achieved easily. A lot of money will be required for research and development.
