NECPR: Progress to targets for greenhouse gas emissions and removals (Annex I) dataset, 2023

Progress to targets for greenhouse gas (GHG) emissions and removals is a dataset under the National Energy and Climate Progress Reports (NECPRs), which is reported every second year (starting in 2023) by EU Member States. The dataset provides information regarding Member State's GHG and removals targets and progress in achieving them. The EEA collects and quality checks this data. The dataset links to data from GHG inventories and projections (also collected by the EEA), as well as Annual Emission Allocations (AEAs). This reporting obligation comes from the Governance Regulation 2018/1999, Implementing Regulation (EU) 2022/2299 (Annex I).

ReFlex: Replicability Concept for Flexible Smart Grids, Wüstenrot Germany

Introduction: By 2020, the community Wuestenrot wants to cover its energy needs through the utilization of renewable energy sources, such as biomass, solar energy, wind power and geothermal energy, within the town area of 3000 hectares. In order to elaborate a practicable scheme for realizing this idea in a 'real' community and to develop a roadmap for implementation, the project 'EnVisaGe' under the leadership of the Stuttgart University of Applied Sciences (HFT Stuttgart) was initiated. Accompanying particular demonstration projects are a) the implementation of a plus-energy district with 16 houses connected to a low exergy grid for heating and cooling, b) a biomass district heating grid with integrated solar thermal plants. Project goal: The aim of the project is to develop a durable roadmap for the energy self-sufficient and energy-plus community of Wüstenrot. The roadmap shall be incorporated in an energy usage plan for the community, that shall be implemented by 2020 and brings Wüstenrot in an energy-plus status on the ecobalance sheet. A main feature within the EnVisaGe project is the implementation of a 14,703-m2 energy-plus model district called 'Vordere Viehweide'. It consists of 16 residential houses, supplied by a cold local heating network connected to a large geothermal ('agrothermal') collector. Here PV systems for generating electricity are combined with decentralised heat pumps and thermal storage systems for providing domestic hot water as well as with batteries for storing electricity. Another demonstration project is a district heating grid fed by biomass and solar thermal energy in the neighbourhood 'Weihenbronn'. It's based on a formerly oil-fired grid for the town hall and was extended to an adjacent residential area.

Trophic interactions in the soil of rice-rice and rice-maize cropping systems

Subproject 3 will investigate the effect of shifting from continuously flooded rice cropping to crop rotation (including non-flooded systems) and diversified crops on the soil fauna communities and associated ecosystem functions. In both flooded and non-flooded systems, functional groups with a major impact on soil functions will be identified and their response to changing management regimes as well as their re-colonization capability after crop rotation will be quantified. Soil functions corresponding to specific functional groups, i.e. biogenic structural damage of the puddle layer, water loss and nutrient leaching, will be determined by correlating soil fauna data with soil service data of SP4, SP5 and SP7 and with data collected within this subproject (SP3). In addition to the field data acquired directly at the IRRI, microcosm experiments covering the broader range of environmental conditions expected under future climate conditions will be set up to determine the compositional and functional robustness of major components of the local soil fauna. Food webs will be modeled based on the soil animal data available to gain a thorough understanding of i) the factors shaping biological communities in rice cropping systems, and ii) C- and N-flow mediated by soil communities in rice fields. Advanced statistical modeling for quantification of species - environment relationships integrating all data subsets will specify the impact of crop diversification in rice agro-ecosystems on soil biota and on the related ecosystem services.

Emmy Noether-Nachwuchsgruppen, Mechanisms regulating the boron nutritional status in rapeseed and Arabidopsis and their implications for the development of boron-efficient genotypes

Boron (B) is an essential microelement for plants. Despite the use of modern fertilization methods, B deficiency still causes losses in agricultural plant production. Even though many positive effects of B on plant growth and physiology have been reported, a large majority of B functions and the regulatory mechanisms controlling the B nutritional status remain unknown. The main objective of this project is to elucidate how the greatly B deficiency-sensitive Brassica crop plants process and regulate their B status during vegetative and reproductive growth. In this context, the project aims at identifying the mode of action of B in mechanisms regulating the B status itself and uncovering those mechanisms contributing to B efficiency in different genotypes. Plant species subjected to investigation will be the agronomically important oilseed and vegetable plant Brassica napus (rapeseed) and its close relative the genetic and molecular model plant Arabidopsis thaliana. Questions addressed within the scope of this project should lead to a detailed understanding of mechanisms controlling B uptake and allocation from the level of the whole plant down to the cellular level. B transport routes and rates will be determined in sink- and source tissues and in developmental periods with a particularly high B demand. A special focus will be on the identification of B transport bottlenecks and the analysis of B deficiency-sensitive transport processes to and within the highly B-demanding reproductive organs. Recent studies in Arabidopsis suggest that Nodulin26-like Intrinsic Proteins (NIPs), which belong to the aquaporin channel protein family, are essential for plant B uptake and distribution. The systematic focus on the molecular and physiological characterization of B. napus NIPs will clarify their role in B transport and will identify novel NIP-associated mechanisms playing key roles in the B response network.To further resolve the mostly unknown impact of the B nutritional status on gene regulation and metabolism, a transcript and metabolite profile of B-sufficient and B-deficient rapeseed plants will be generated. Additionally, an Arabidopsis transcription factor knockout collection (greater 300 lines) will be screened for abnormalities in responses to the B nutritional status. This will identify yet unknown B-responsive genes (transcription factors and their targets) and gene products (enzymes or metabolite variations) playing key roles in signalling pathways and mechanisms regulating the B homeostasis. Boron (in form of boric acid) and arsenite (As) share in all likelihood the same NIP-mediated transport pathways. To assess the consequences of this dual transport pathway the so far unstudied impact of the plants B nutritional status on the accumulation and distribution of As will be investigated in B. napus. Moreover, the current dimension of the As contamination of Brassica-based food products, to which consumers are exposed to, will be analyzed. usw.

Carbon, water and nutrient dynamics in vascular plant- vs. Sphagnum-dominated bog ecosystems in southern Patagonia

In bog ecosystems, vegetation controls key processes such as the retention of carbon, water and nutrients. In northern hemispherical bogs, a shift from Sphagnum- to vascular plant-dominated vegetation is often traced back to Climate Change and increased anthropogenic nitrogen deposition and coincides with substantially reduced capacities in carbon, water and nutrient retention. In southern Patagonia, bogs dominated by Sphagnum and vascular plants coexist since millennia under similar environmental settings. Thus, South Patagonian bogs may serve as ideal examples for the long-term effect of vascular plant invasion on carbon, water and nutrient balances of bog ecosystems. The contemporary balances of carbon and water of both a bog dominated by Sphagnum and vascular plants are determined by CO2- H2O and CH4 flux measurements and an estimation of lateral water losses as well as losses via dissolved organic and inorganic carbon compounds. The high time resolution of simultaneous eddy covariance measurements of CO2 and H2O in both bog types and the strong interaction between climatic variables and the physiology of bog plants allow for direct comparisons of carbon and water fluxes during cold, warm, dry, wet, cloudy or sunny periods. By the combination with leaf-scale measurements of gas exchange and fluorescence, plant-physiological controls of photosynthesis and transpiration can be identified. Long-term peat accumulation rates will be determined by carbon density and age-depth profiles including a characterization of peat humification characteristics. A reciprocal transplantation experiment with incorporated shading, liming and labeled N addition treatments is conducted to explore driving factors affecting competition between Sphagnum and vascular plants as well as the interactions between CO2-, CH4-, and water fluxes and decisive plant functional traits affecting key processes for carbon sequestration and nutrient cycling. Decomposition rates and driving below ground processes are analyzed with a litter bag field experiment and an incubation experiment in the laboratory.

Nasselektrofilteranlage Sulfitzellstofffabrik

Das Unternehmen Essity Operations Mannheim GmbH ist ein Tochterunternehmen der Essity AB mit Hauptsitz in Stockholm, Schweden. Essity betätigt sich im Hygiene- und Gesundheitsbereich und vertreibt  Produkte und Lösungen in rund 150 Länder. Am Standort in Mannheim betreibt es ein Sulfit-Zellstoffwerk und eine Papierfabrik zur integrierten Produktion von Sulfitzellstoff nach dem Magnesiumbisulfitverfahren und Hygienepapieren. Die bisherige Verfahrenstechnik zur Chemikalienrückgewinnung und Rauchgasreinigung einer Sulfitzellstofffabrik ist sehr komplex und erfolgt in mehreren Stufen. Der Prozess beginnt mit der Verbrennung der bei der Zellstofferzeugung anfallenden Ablauge. Diese enthält die an Schwefel gebundenen Lingninkomponenten (aus Fichten- und Buchenholz) und Magnesiumverbindungen aus dem Magnesiumbisulfit (Kochsäure), welches bei der Zellstoffkochung zum Einsatz kommt. Dabei entstehen neben der Abwärme Schwefeldioxid und Magnesiumoxid. Das entstehende Rauchgas wird über Zyklonabscheider geführt, um einen Großteil des Magnesiumoxids abzuscheiden. Da dies nicht vollständig gelingt, verbleibt nutzbares Magnesiumoxid im Rauchgas und wird in die Umwelt abgegeben. Das Rauchgas durchläuft nun eine 4-stufige Wäsche, bei der Schwefeldioxid aus dem Rauchgas ausgewaschen wird. Das nasse Rauchgas wird über einen 134 Meter hohen Kamin an die Umwelt abgegeben. Nachteile des herkömmlichen Verfahrens sind, dass schadstoffhaltige Aerosole und auch Staub, die nicht abgeschieden werden können, in die Umwelt gelangen. Zusätzlich können die genannten Prozesschemikalien nicht vollständig zurückgewonnen werden. Das Magnesiumoxid setzt sich im Kamin ab. Um diese Nachteile aufzufangen, ist geplant, einen Nasselektrofilter (NEF) zu installieren. Dadurch wird ermöglicht, dass das Rauchgas nach den vier Waschstufen in zwei verfahrenstechnisch voneinander getrennten Prozessschritten über einen Gegenstromwäscher mit darauffolgendem NEF geführt werden kann. Eine solche Prozesstrennung ist mit dem bisher in Sulfitzellstoffwerken üblichen Abgasreinigungsverfahren (Sulfitwäscher) nicht möglich, da hierbei beide Schritte unmittelbar miteinander verknüpft sind. Die Trennung hat den erheblichen Vorteil, dass sich einerseits der Waschprozess und andererseits die Entfernung der Aerosole getrennt auslegen, betreiben und optimieren lassen. Dies führt im Ergebnis zu einer effizienteren Abscheidung der Aerosole. Entsprechend können die Staub- und SO 2 -Emissionen kontrollierter und damit in unterschiedlichen Betriebszuständen reduziert werden. Darüber hinaus soll der Venturi-4-Wäscher um einen weiteren Wäscher bzw. eine zusätzliche Magnesiumoxid-Eindüsung erweitert werden. Dadurch sollen Staub und Schwefeldioxidemissionen weiter reduziert und Prozesschemikalien zurückgewonnen werden. Mit diesem Vorhaben soll der Stand der Technik zur Emissionsminderung für Chemikalienrückgewinnungskessel von Sulfitzellstoffwerken maßgeblich weiterentwickelt und die einschlägigen Emissionsgrenzwerte erheblich unterschritten werden. Es sollen bis zu 50 Tonnen Feinstaub und 50 Tonnen Schwefeldioxid pro Jahr eingespart werden. Dies entspricht jeweils mindestens einer Halbierung der Emissionsmengen in den Abgasen im Vergleich zum bisherigen Stand. Zusätzlich können durch eine erfolgreiche Umsetzung der innovativen Technik 45 Tonnen Magnesiumoxid und ca. 25 Tonnen Schwefel mehr gegenüber dem Stand der Technik zurückgewonnen werden. Daraus soll sich eine Einsparung von rund 104 Tonnen Kohlenstoffdioxid-Äquivalenten, bezogen auf die Primärherstellung von Magnesiumoxid und Schwefeldioxid, ergeben.
