Among the twenty-nine measures contained in the draft of the Strategy for the Improvement of Air Quality in Castilla y León four have biofuels (biomass, biogas and biofuels) to achieve one of the essential objectives: that in 2029 values are met guide of the World Health Organization for all primary pollutants and in all atmospheric zones of the region. The inclusion of biomass as another element to improve air quality occurs in the context of other plans and documents that question this contribution.
The Air Quality and Climate Change Plan of the Madrid City Council , in which the most famous measure known as Central Madrid is framed, in addition to scientific positions or reports from organizations such as the Fundación Renovables have shown their misgivings when not rejecting the setting for thermal biomass, especially in cities. Castilla y León, however, remains one of the autonomous communities where it finds shelter.
He has shown it again with the publication of the draft of the Strategy for the Improvement of Air Quality in Castilla y León, currently in public exhibition and open to make contributions until February 20, 2019. One of its objectives is that at the end of its period of validity, in 2029, “in Castilla y León WHO guide values for all primary pollutants and in all the atmospheric zones of the region “.
At the same time, they also consider that the same year “the European Union reference values for ozone should not be exceeded in all the atmospheric zones of the region”. All this is linked to “the consequent measures of action for the improvement of air quality and the reduction of air pollution”.
Biomass, but also gas
Although twenty-eight measures are announced, twenty-nine appear in the final count. In four of them, different types of biofuels are taken into account, with two dedicated to biomass. Solid biofuels and their thermal uses are the main protagonists within bioenergy.
The measure identified as RCI.9 refers to the promotion of the implementation of clean energy for heating and hot water in the residential-commercial-institutional sector (RCI). It is explicit that “the objective is to reduce the consumption of diesel, LPG and electricity mainly, by clean and alternative energies such as biomass, solar energy or geothermal energy”.
Among the more specific sub-measures, gas also takes center stage, since, although there is talk of “renewal of conventional gas boilers by others of high energy efficiency”, when mention is made of the substitution of gasoil and coal with ” a new specific line of subsidies “, natural gas is expressly mentioned. It is also proposed to expand its distribution network “to municipalities that still do not have it”.
Relevance for heat networks
After these points the “promotion of the installation of renewable energy boilers such as biomass, solar or geothermal energy, especially for the generation of sanitary hot water and heating, or district heating projection in the main cities. The creation of these urban heat networks is cited in other sections of the strategy.
Biomass is also present in the measure I.7 of “impulse to the use of renewable energies in the industrial sector”, which “is aimed at implementing actions that promote and inform companies of the possibilities they have to generate renewable energy to from fuels such as biomass, solar energy or heat. ”
Incentives for biogas. By-pass biofuels
For the biogas is the measure AG.25 “development of incentive lines for the development of centralized plants for the management of livestock excreta through biodigestion with energy use”. As sub-measures, the “promotion through various incentives of the development of biodigestion plants of livestock excreta” stands out.
Two other sub-measures are the “preparation of a study on the availability of livestock excreta by county” and the “development of demonstrative actions and R & D & I of the operation of facilities for the use of biogas”.
Those with a less defined and exclusive measure are biofuels. This is the TM.16: “creation of residential priority areas and low emission areas, and reduction of the urban speed limit to 30 km / h”. As a sub-measure, there appears the “impulse to the use of vehicles of zero emissions or very low emissions: electricity, liquefied petroleum gas or autogas LPG, natural gas in its two states (compressed or liquefied), biofuels and hydrogen, both particular level, as in a very special way in the fleets of public vehicles “.
