Konferensbidrag (refereegranskat)abstract
- The complexity of systems continues to increase rapidly, especially due to the multi-level integration of subsystems from different domains into cyber-physical systems. This results in special challenges for the efficient verification and validation (V&V) of these systems with regard to their requirements and properties. In order to tackle the new challenges and improve the quality assurance processes, the V&V workflows have to be documented and analyzed. In this paper, a novel approach for the workflow modelling of V&V activities is presented. The generic approach is tailorable to different industrial domains and their specific constraints, V&V methods, and toolchains. The outcomes comprise a dedicated modelling notation (VVML) and tool-support using the modelling framework Enterprise Architect for the efficient documentation and implementation of workflows in the use cases. The solution enables the design of re-usable workflow assets such as V&V activities and artifacts that are exchanged between workflows. This work is part of the large scale European research project VALU3S that deals with the improvement and evaluation of V&V processes in different technical domains, focusing on safety, cybersecurity, and privacy properties.

Petrochemicals and Climate Change : Tracing Globally Growing Emissions and Key Blind Spots in a Fossil-Based Industry
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- With the risk of climate breakdown becoming ever more pressing as the world is on track for 2.7 degrees warming, pressure is increasing on all sectors of the economy to break with fossil fuel dependence and reduce greenhouse gas (GHG) emissions. In this context, the chemical industry and the production of important basic chemicals is a key sector to consider. Although historically a driver of economic development, the sector is highly dependent on fossil resources for use as both feedstock and fuel in the production of as well organic as inorganic chemicals. The chemical industry demands both petroleum fractions and natural gas. Petroleum fractions such as naphtha and petroleum gases are used as feedstocks for building block chemicals and polymers (e.g., benzene and polyethylene), while natural gas is used for methanol and ammonia. Indeed, the sector is associated with both large process emissions as well as energy related emissions. Our results demonstrate that in 2020 direct GHG emissions from the petrochemical sector amounted to 1.8 Gt CO2eq which is equivalent to 4% of global GHG emissions. Indirect GHG emissions resulting from the activities in other industries supplying inputs for the petrochemical industry accounted for another 3.8 Gt CO2eq. The petrochemical industry is thus associated with a total of 5.6Gt CO2eq of GHG emissions, equivalent to ~10% of global emissions. Over the past 25 years, emissions associated with petrochemicals have doubled and the sector is the third most GHG emitting industry. This increase is fueled by large growth of petrochemicals production as well as growth in regions with high indirect emissions, i.e., in energy systems with high dependence on coal and other fossil fuels. Over the past decades, the industry has grown rapidly in the Asia-Pacific region especially in China which in 2020 was the source for about 47% of global GHG emissions associated with petrochemicals. USA accounts for 6% of the emissions from the industry and Europe for 5%. The BRIC group of countries, which except for China also includes Brazil, India, and Russia, currently accounts for 57% of GHG emissions from petrochemicals, showing that the emissions from this sector are more geographically clustered in these countries than emissions from other sectors.Proper disaggregated and comparative analyses of key products is currently not possible. Data confidentiality and a high reliance on proxy data limit the reliability of LCA and stands in the way of mapping climate impacts. A strong demand of chemicals life cycle inventory (LCI) data for environmental footprinting has resulted in a general increase of chemicals data in many LCI databases, but the energy demands both for heat and electricity are typically not well-documented for production processes outside the main bulk chemicals. If incinerated at end-of-life plastics and other chemical products will emit embodied carbon as CO2 and if landfilled there is a risk of slow degradation with associated methane emissions. Global estimates based on most LCA datasets will thus significantly underestimate emissions from the chemical industry.The multitude of value chains dependent on the petrochemical industry makes it an important contribution to life cycle emissions in many sectors of the economy. Petrochemicals are used as an intermediate input in many industries and the emissions associated with them thus propagate through the economy, with final demand in manufacturing industries and services being associated with the largest shares of emissions from chemicals. The impacts and emissions downstream in value chains is however poorly understood and disclosure by petrochemical producers is lacking and insufficient. While disclosure of emissions in the industry has increased over the past decades, it remains partial and shows inconsistencies over time. This is due to issues such as different reporting standards, large discrepancies in the extent of disclosure as well as various other gaps and inconsistencies in reporting. This holds for all scopes, although Scope 1 emissions are better covered. Only some firms disclose information about downstream Scope 3 emissions including end-of-life for final products. Emission targets set by firms in the industry do not correspond to the challenge of large and rapid emission reductions. Many targets include only parts of operations and transparent, standardized target-setting is lacking. Reported emission reduction initiatives to achieve targets are far from sufficient focusing mainly on efficiency improvements or insubstantial parts of the operation. Shifting to renewable energy is a key for rapid emission reductions in the industry, yet few firms report strategic targets for this shift. As the industry has historically been closely linked to and integrated with the energy sector it holds a great potential for engaging with the deployment and adoption of renewable energy, although this implies a transformation of the knowledge base and resource allocation in the industry which is still focused on fossil fuels. Roadmaps and scenario analyses show that apart from a shift to renewable energy, a transformation of the industry relies on the deployment of key technologies which are not yet fully developed. This includes new technologies for hydrogen production, e.g., electrolytic (green) hydrogen or hydrogen produced with carbon capture and storage (CCS). New chemical synthesis pathways based on captured carbon, so called carbon capture and utilization (CCU) is also highlighted, but the massive demand for renewable energy associated with this pathway is a significant barrier to its adoption in the near term. The report shows how efficiency improvements continues to be the main focus for reducing the climate impact of petrochemicals, but that this is a completely inadequate approach for achieving the emissions reductions necessary in the coming decades. Breakthrough technologies are unlikely to be deployed at a rate consistent with international climate targets, and there is a great risk in relying on the promises of technologies which are yet to be proven at scale. The large knowledge gaps that remain are key barriers for effective governance of the transition.

Measuring waste prevention and reuse: digital opportunities : Using the digitalisation of society to inform policy
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The data generated in our digital society can be harnessed to generate policy-relevant indicators on waste prevention and reuse, and be used to fill in the gaps left by official data and statistics. This project elaborates where the greatest potentials lie for improving the monitoring of waste prevention and reuse, and presents a roadmap for improving the monitoring of waste prevention in the Nordic countries. This is based mapiping the EU reporting demands for waste prevention and reuse and the methods currently employed in the Nordic countries to measure waste prevention and reuse, as well as an investigation of the methods used in other European countries together with a suite of case studies of novel methods for measuring waste prevention and reuse.

Petrochemicals and climate change: Powerful fossil fuel lock-ins and interventions for transformative change
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- With the risk of climate breakdown, pressure is increasing for all sectors of the economy to break with fossil fuel dependence and reduce greenhouse gas emissions. In this context, the chemical industry requires more focused attention as it uses more fossil-fuel based energy than any other industry and the production of chemicals is associated with very large emissions. Beyond the climate crisis, the chemical industry significantly impacts several critical dimensions of sustainability, including the planetary boundaries for novel entities, biosphere integrity, and ocean acidification. In this report, we focus on the petrochemical sector, which represents the largest share of the chemicals industry and is generally understood to refer to the part of the industry that relies on fossil-fuel feedstocks from oil, gas, and coal. The petrochemicals sector produces chemicals mainly used for plastics and fertilisers, but the products also end up in paints, pharmaceuticals, pesticides, and other applications. This report provides a critical exploration of the petrochemical sector to strengthen awareness of its relevance to the climate crisis and to provide tools and recommendations for decision-makers in different domains to initiate, support, and accelerate much-needed transformation. The report highlights the rapid expansion of the petrochemical sector as well as the range and growth of economic, infrastructural, and political interlinkages with the fossil fuel extraction sector. It argues that these developments and dynamics are crucial to understanding pathways, strategies, and interventions for a low-carbon transition for petrochemicals.

A Proposal for the Classification of Methods for Verification and Validation of Safety, Cybersecurity, and Privacy of Automated Systems
- 2021
-
Ingår i: 14th International Conference on the Quality of Information and Communications Technology (QUATIC 2021).
-
Konferensbidrag (refereegranskat)abstract
- As our dependence on automated systems grows, so does the need for guaranteeing their safety, cybersecurity, and privacy (SCP). Dedicated methods for verification and validation (V&V) must be used to this end and it is necessary that the methods and their characteristics can be clearly differentiated. This can be achieved via method classifications. However, we have experienced that existing classifications are not suitable to categorise V&V methods for SCP of automated systems. They do not pay enough attention to the distinguishing characteristics of this system type and of these quality concerns. As a solution, we present a new classification developed in the scope of a large-scale industry-academia project. The classification considers both the method type, e.g., testing, and the concern addressed, e.g., safety. Over 70 people have successfully used the classification on 53 methods. We argue that the classification is a more suitable means to categorise V&V methods for SCP of automated systems and that it can help other researchers and practitioners.

Comparison and interactions between the long-term pursuit of energy independence and climate policies
- 2016
-
Ingår i: Nature Energy. - : Springer Science and Business Media LLC. - 2058-7546. ; 1:6
-
Tidskriftsartikel (refereegranskat)abstract
- Ensuring energy security and mitigating climate change are key energy policy priorities. The recent Intergovernmental Panel on Climate Change Working Group III report emphasized that climate policies can deliver energy security as a co-benefit, in large part through reducing energy imports. Here, using five state-of-the-art global energy-economy models and eight long-term scenarios, we show that while deep cuts in greenhouse gas emissions would indeed reduce energy imports, the reverse is not true: ambitious policies constraining energy imports would have only an insignificant impact on climate change. Restricting imports of all fuels would lower twenty-first-century emissions by only 2%–15% against the Baseline scenario as compared with a 70% reduction in the 450 scenario. Restricting only oil imports would have virtually no impact on emissions. The modelled energy independence targets could be achieved at policy costs comparable to those of existing climate pledges but a fraction of the cost of limiting global warming to 2 ◦ C.

Konferensbidrag (refereegranskat)abstract
- The Origins Space Telescope will trace the history of our origins from the time dust and heavy elements permanently altered the cosmic landscape to present-day life. How did galaxies evolve from the earliest galactic systems to those found in the universe today? How do habitable planets form? How common are life-bearing worlds? To answer these alluring questions, Origins will operate at mid-and far-infrared wavelengths and offer powerful spectroscopic instruments and sensitivity three orders of magnitude better than that of Herschel, the largest telescope flown in space to date. After a 3 1/2 year study, the Origins Science and Technology Definition Team will recommend to the Decadal Survey a concept for Origins with a 5.9-m diameter telescope cryocooled to 4.5 K and equipped with three scientific instruments. A mid-infrared instrument (MISC-T) will measure the spectra of transiting exoplanets in the 2.8-20 μm wavelength range and offer unprecedented sensitivity, enabling definitive biosignature detections. The Far-IR Imager Polarimeter (FIP) will be able to survey thousands of square degrees with broadband imaging at 50 and 250 μm. The Origins Survey Spectrometer (OSS) will cover wavelengths from 25-588 μm, make wide-area and deep spectroscopic surveys with spectral resolving power R ∼ 300, and pointed observations at R ∼ 40,000 and 300,000 with selectable instrument modes. Origins was designed to minimize complexity. The telescope has a Spitzer-like architecture and requires very few deployments after launch. The cryo-thermal system design leverages JWST technology and experience. A combination of current-state-of-the-art cryocoolers and next-generation detector technology will enable Origins' natural backgroundlimited sensitivity.
