I am pleased to announce the publication of my new article "Animal displacement from marine energy development: Mechanisms and consequences", in Science of the Total Environment, written alongside PNNL colleagues and international partners. The article provides clarity regarding definition, mechanisms, effects, and methods of investigation of animal displacement in the context of marine renewable energy, and is available online in open access at this link: https://lnkd.in/giYFaDc7 #marinerenewableenergy #environmentaleffects #peerreview

During our engagement efforts regarding #offshorewind in the #GulfofMaine, Bureau of Ocean Energy Management gets a lot of questions, particularly from fishermen, about potential effects of electromagnetic fields (EMF) from transmission cables on marine species. While a lot of research has been done, it's often hard to summarize that information in an easily digestible way. This recent article from the Provincetown Independent does a great job highlighting the takeaways from several of the most prominent, frequently cited studies (including interviews with the study authors!): https://lnkd.in/eVsb4t8U Undersea, EMF-producing cables have co-existed with marine life and fisheries for decades, and the existing science suggests effects are minimal and highly localized. With that said, fishermen have raised good questions that will help guide ongoing and future research, particularly with respect to floating offshore wind.

Today IETA published its Geostorage and Carbon Crediting Handbook, offering insights into the evolving landscape of methodologies that enable projects to monetize the geologic storage of CO2. The handbook summarizes the current state of carbon geostorage methodologies including Clean Development Mechanism, ACR at Winrock International, Verra (CCS initiative), Puro.earth, Gold Standard, Isometric and Alberta & British Columbia’s compliance programs. This is a great resource for project developers with a pathway that requires the geologic storage of CO2 by providing an initial understanding of methodologies currently available and those still under development. #CCS #GeologicStorage

✨ Employee Spotlight: Colette Gelas ✨ Colette is one of our remote sensing experts. Having completed her PhD on the utilization of radar imagery (PolSAR P-band) in calculating biomass, she is an essential part of the team. She helps us overcome the difficulties that normally arise when working with satellite imagery such as image selection, and dealing with cloud cover. Her radar expertise allows us to see below the canopy and produce ever improving biomass calculations. "I develop SAR-based indicators to enhance our height and biomass machine learning models. Using Sentinel1 (C-band) and Alos Palsar (L-band) data inversion enables accurate calculation of biomass and height metrics across various Earth ecosystems, including tropical rainforests that are often cloud-obscured. SAR data is minimally affected by weather conditions and light, allowing us to acquire information beneath the canopy level. " Colette, we appreciate your year of hard work! #teamwork #remotesensing #mrv #naturebasedsolutions

"Like Galileo’s telescope, direct biomass estimation brings a Copernican revolution in our understanding of forest carbon dynamics. It does more than providing a cost-effective and scalable alternative to traditional approaches – it makes a new level of understanding in carbon accounting possible" - Marco Albani, Chloris CEO and Co-Founder. Read the latest World Economic Forum article by our CEO Marco Albani "How direct biomass estimation can improve forest carbon accounting". ⬇ #carbonaccounting #remotesensing #biomass

“Canadian integrated #CCS solution enhancing North Sea #carbonstorage project” August 2, 2024, - Dragana Nikše “Norwegian energy company Sval Energi has selected a comprehensive #carboncaptureandstorage (CCS) solution developed by Canada-based Computer Modelling Group (CMG) for one of its #CO2 transportation and storage projects in the Norwegian North Sea.” “The project in question – Trudvang, envisages #capturingCO2 from #industrialemissionsources in Northern Europe and transporting it to the Trudvang store for injection and #permanentstorage beneath the seabed. With a startup targeted in 2029, it has the potential to store 9 million tons of CO2 annually. “ “The Canadian tech firm explains that its integrated CCS workflow features solutions developed in-house, as well as those by Kongsberg Digital, combining #reservoirsimulation , #geochemistry and #geomechanics , steady-state and transient #wellboreanalysis , and #surfacepipelinenetworksimulation into one comprehensive, #interactiveCO2model .” https://lnkd.in/e58WVCkf?

While demand for geothermal energy grows, permitting continues to stymie development. #FederalPermitting attorney Hadassah (Dessa) Reimer spoke with Law360 on the unique challenges of endangered species on federal public lands, saying, "Almost every geothermal facility, there's often a surface feature [which sometimes] support unique species. The issue is: How do we get this permitted with this newly discovered species that's unique to the system, and how can we coexist?"

[#ResearchAtSea] The observation buoy named APPEAL was redeployed on 26 November 2023 off Groix & Belle-Île after major maintenance (cleaning, changing the structure and the energy park) and the installation of an innovative experimental device. The aim is to characterise the development of living organisms on submerged infrastructures such as the floating wind turbines that will be deployed in Southern Brittany by 2031. This deployment is part of the wider #BIODHYL research project, which aims to define a rigorous protocol for characterising the biocolonisation of mooring lines and electric cables. ▶ https://lnkd.in/evKpei8g EDF Renouvelables, Ifremer, OW Ocean Winds, RTE, RWE, Shell, TotalEnergies, Nantes Université, Université de Toulon #FOWT #biocolonisation #buoy #mooring #cable #characterisation
