What's the best low-carbon way to power vehicles? A groundbreaking study in Joule examines the potential of green hydrogen to revolutionize transportation across ground, air, and marine sectors. While green hydrogen presents promise in the hard-to-abate areas of transportation, significant investments in infrastructure and technology are needed to realize its full potential. For passenger vehicles and most road transport, the most efficient use of power is electric vehicles, sometimes by a factor of 5-10x over other “emissions-free” methods including hydrogen! https://lnkd.in/e9GZjv3f #climate #energy #transportation #ev #renewables #emissions #innovation

Canada builds noise-cleaning highways that erase traffic sound Along several Canadian highways, engineers have installed a new type of sound barrier that doesn’t just block noise — it absorbs and neutralizes it. The system uses porous mineral foam layered with micro-cavities that draw in sound waves and dissolve them through controlled vibration transfer. Instead of reflecting noise back into neighborhoods, the material essentially “swallows” traffic noise. The panels were first tested on a quiet stretch outside Vancouver, where residents noticed an immediate difference. Car engines, braking, and tire friction dropped to nearly silent levels when passing the barrier. Microphones placed behind the wall showed up to a 92% noise reduction, far beyond traditional concrete or metal sound barriers. This level of quiet reshaped the environment for both people and wildlife. Urban planners believe these noise-cleaning barriers could dramatically improve life quality in dense areas. Children’s sleep patterns, school performance, and general stress levels often suffer near highways. With this new technology, Canadian suburbs could experience nighttime quiet even with major roads nearby. Birds and small mammals may also return to habitats once disturbed by constant mechanical noise. The mineral foam is highly recyclable, weather-resistant, and stable across temperature extremes. Engineers designed the panels to be repaired easily and replaced section-by-section, making large-scale deployment affordable. Several provinces have already committed to introducing the barriers near hospitals, parks, and residential complexes. Canada’s innovation shows that revolutionizing infrastructure doesn’t always require cutting-edge electronics — sometimes, the quietest solutions are built from simple materials reshaped with precision. #engineering

When nature becomes the smartest engineer 🌵 South Africa is redefining sustainable housing with an idea that’s as simple as it is brilliant. In arid regions like the Northern Cape, desert-native cactus pads are being used as natural insulation for eco-roofs, especially in low-income housing. The science behind it is elegant: ☀️ By day: Thick, fleshy cactus layers absorb extreme heat, stopping it from radiating indoors. 🌙 By night: As temperatures fall, moisture slowly released from the cactus cools the surrounding air, creating a passive thermal buffer. What makes this innovation powerful isn’t just the science — it’s the accessibility. Free and locally available Biodegradable and pest-resistant No machinery, processing, or electricity required Installed by simply layering harvested pads, sometimes mixed with clay tiles for durability Residents report cooler homes during scorching days and less dryness at night. For communities where conventional insulation is unaffordable, this low-tech solution delivers high-impact comfort. Now, eco-architecture students across Africa are studying this model — proof that climate-smart solutions don’t always come from labs, but often from listening to the land itself. Sometimes, the future of sustainable housing is growing right by the roadside.

Public attention has centred on the first #Omnibus package (CSRD/CSDDD), but the EU has since rolled out five more packages - four of these weaken sustainability standards (and this often escapes our attention). Here is an overview: 🔵 Omnibus III - Agriculture  Simplifies conditionality and controls related to the EU's Common Agricultural Policy (CAP). Fewer inspections and less frequent checks will make it harder to ensure agricultural practices meet environmental conditionality. 🟢 Omnibus IV - Digitalisation (incl. Batteries) Two-year “stop-the-clock” on battery due-diligence (now 08/2027). This slows down safeguards against environmental and human-rights harms in minerals extraction, precisely as EU battery demand scales. 🟤 Omnibus V - Defence Defence needs allow broader use of chemicals that would otherwise be more strictly regulated; existing rules (like REACH) can be applied less strictly for the defence sector under exceptions. 🔴 Omnibus VI - Chemicals Streamlines labelling, cosmetics, and fertiliser rules; but reduced on-pack information, longer transition periods, and narrower bans (e.g. certain CMRs in cosmetics) weaken transparency and environmental safeguards. Further planned sustainability simplifications in 2025: (1) review of #SFDR in Q4 2025 (likely to be delayed to Q1 2026), (2) an "Environmental Omnibus" focused on emissions, circularity and waste management. 👉 Cutting red tape and streamlining regulations is not inherently negative. But the EU is pursuing this at high speed and with far-reaching consequences for nature and society. These impacts must be carefully assessed and weighed against the potential cost savings.

Driving the Future: Advanced Biofuels Paving the Way for Sustainable Transport Decarbonizing the transport sector is crucial for achieving global climate and energy targets due to its significant contribution to greenhouse gas emissions and reliance on fossil fuels. Advanced biofuels play a pivotal role in this transformation, offering a low-carbon solution for both immediate and long-term challenges. The IEA Bioenergy Technology Collaboration Programme has been at the forefront of this effort, establishing a comprehensive database of facilities producing advanced biofuels since 2009. This database, updated in November 2024, now includes 258 active entries, showcasing technologies like Alcohol-to-Jet, E-Fuels Biomass Hybrids, Fast Pyrolysis, Fermentation, Gasification, Hydrothermal Liquefaction, and Hydrotreatment. Feedstock availability remains a critical factor, influencing both the scalability and sustainability of biofuel production. While oil-based residues like used cooking oil and animal fats are valuable, their limited supply necessitates exploring biomass residues such as agricultural waste and forestry by-products. Developing and commercializing advanced biofuel technologies is key to unlocking this potential. Sustainability frameworks are essential to ensure robust GHG emission certification and verification. The future markets for advanced biofuels are expected to thrive in long-distance transport sectors like aviation, maritime shipping, and heavy-duty road transport. The aviation industry, in particular, is committed to reducing its carbon intensity through renewable fuels and biofuels. Emerging economies are accelerating biofuel development, driven by increasing energy demand, abundant natural resources, and the need for sustainable development. Governments are implementing policies like blending mandates and subsidies to boost biofuel production, creating economic opportunities and reducing fossil fuel reliance. Despite progress, scaling up biofuel production to meet ambitious 2030 targets remains challenging. International collaboration and knowledge exchange are vital to overcoming these hurdles and realizing the full potential of biofuels in a sustainable energy future.

The miracle of flight opens up the world to us – but at a cost. Aviation contributes 2.5% of global carbon emissions and is responsible for an estimated 4% of human-caused global warming. At the same time, it will take decades before electrified planes are viable, and thus decades before flying can be powered by renewable energy sources. We therefore urgently need an alternative and cleaner way of powering the planes that are crucial to modern life as we know it. This month, my colleague Jennifer Ozimkiewicz and I explore how sustainable aviation fuels, particularly those made from oilseed cover crops, could be the solution we seek. An innovative type of biofuel, their carbon footprint is dramatically lower than that of conventional jet fuel – and, when done right, they are alternated with food crops, thus providing farmers with an additional source of income and complementing, rather than displacing, vital sources of nutrition. We believe that ambitious targets and rigorous sustainability standards are needed to create trust in the product and in the market, while innovative industry alliances can further foster technological advancement. A successful framework for SAF is crucial to making green aviation a reality.

“We’re taking a diesel engine and adapting it to run on alternative fuels. Our primary test fuel at the moment is Hydrogen.” At bauma I caught up with Ian Evans from Perkins Engines Company Limited to hear about Project Coeus, which is about creating a drop-in hybrid power solution that combines spark-ignited alternative fuels like hydrogen and electric drive systems to mimic the performance and responsiveness of diesel. As Ian explained: “We’re hybridising the system. The electric motor and battery fill in for torque and transient response, so customers get the same performance they’re used to, just with low or zero carbon fuels.” This is serious engineering, and it’s not happening in isolation. Project Coeus is a collaborative effort, involving: • Loughborough University, providing advanced insights into combustion dynamics, flow fields, and aftertreatment optimisation • Equipmake, supplying the motor generator unit, which integrates directly onto the flywheel housing. Ian: “It’s a fantastic piece of development work. From the combustion system through to integration of the hybrid electric components, this has been about pushing the envelope to deliver practical, scalable solutions.” What’s especially important is the flexibility. While hydrogen is the primary test fuel today, the team is also exploring ethanol, methanol, and biomethane, with the goal of offering a platform that can adapt to regional fuel availability and specific customer needs. Ian: “Fuel sources around the world are different. This isn’t about one answer, it’s about understanding how we design and develop engines that deliver the right mix of performance and emissions reduction across multiple fuels.” Back at the Perkins Engines Europe Research and Development Centre in Peterborough, the team is already running these systems through their paces, with real-time testing, live performance data, and continuous engineering iteration. Ian: “Every single thing is monitored. All the performance is being captured. It’s about creating a whole solution, not just for tomorrow, but for the long-term future of our industry.” #Bauma2025 #HydrogenEngines #HybridPower #AlternativeFuels #ConstructionInnovation #PerkinsEngines #ProjectCoeus #EngineeringExcellence #SustainablePower #Bauma #dieselengines #electricpower 

The climate is changing faster than many business models are built to handle. But for those looking ahead, climate adaptation is emerging not just as a necessity — but as one of the most significant financial opportunities of the coming decades. According to a new report by GIC, Singapore’s sovereign wealth fund, and Bain & Company, climate adaptation solutions could generate $4 trillion in annual revenue by 2050 — with $2 trillion of that growth driven directly by global warming. The market value of companies offering adaptation products and services is expected to climb from $2 trillion today to $9 trillion, representing a major investment opportunity across industries. What exactly does adaptation mean for business? Unlike mitigation, which targets the reduction of emissions, adaptation focuses on protecting systems, infrastructure and people from the physical impacts of climate change. This includes flood protection, wildfire response, drought-resilient agriculture, backup energy systems, heat-resistant building materials and precision weather forecasting. The investment case for adaptation is resilient across all climate pathways, with less than 4% variation in market value projections even under different warming scenarios. This makes adaptation a strategically sound long-term investment — relatively insulated from the political and regulatory uncertainties that can impact mitigation-focused ventures. Critically, the report finds that current market forecasts may significantly undervalue the future revenue potential of adaptation, suggesting that investors could benefit from upside surprises as awareness and demand accelerate. Growth will come from both emerging technologies and scaled deployment of proven solutions. For businesses, this means both innovation and implementation will drive returns — whether through the development of next-generation cooling systems or the mass rollout of flood defences in vulnerable regions. With the world likely to overshoot the 1.5°C target, adaptation is no longer optional. It is becoming integral to business continuity, supply chain resilience and long-term value creation. Yet adaptation finance still lags, attracting only a fraction of the capital required to meet projected needs. For companies and investors willing to act now, this gap represents both a responsibility and an opportunity — to lead in building resilience while capturing a share of one of the defining growth markets of the 21st century.

Imagine an olive grove for example. An agricultural set up that can either be a mono plantation constantly 'fighting' nature or a more biodiverse ecosystem looking to collaborate with nature. Example 1: Apply artificial fertilisers that disrupt the microbial-fungal exchange networks that understand and naturally build and balance soil life. The knock on effect is a reducing of natural fertility further and weakening of plant health. Then the the application of herbicides to remove all vegetation, creating bare soil and denude biodiversity that supports natural predators and brings balance. Fungi become imbalanced and more aggressive as nature looks to counteract the poisoning. Perhaps a bit of tilling now as well to help oxide the soil, expose any microbial soil life to harmful UV rays and make compaction and run off worse long term. Next pesticides are used in theory to maintain quality and yield while systematically whipping out most if not all biodiversity and poisoning the host plants. Then fungicidal use is needed to support trees now more susceptible to infections, killing any beneficial fungi that remain. This then leads to a fungi- bacteria imbalance and disease becomes inevitable as the more aggressive pathogens such as gram negative bacteria thrive and cause disease and dieback. When it rains the flood / drought double sided coin comes into play and most water runs off the compacted soil and is lost. Example 2: Soil is kept permanently covered with diverse perennial and annual local grasses and forbs. Soil organic matter is slowly increased. The multi sized roots opening up the soil and aiding de-compaction while root exudates feed the soil biology. Leguminous species collaborate with nitrogen fixing bacteria to create nitrogen banks in the soil. The grasses are cut regularly to help build organic matter. When it rains the majority of the water is held in the soil and is there for slow release. Non use of pesticides allow beneficial biodiversity to set up home and start to create balance. Spiders often being the key to biodiversity balance. Nature's natural predators bring balance. By creating the right conditions for fungal species to proliferate, the fungal - bacterial balance is restored. Aggressive pathogen bacterial species tend to be kept in check and not spread into the realm of disease causing. A bit simplified, but I know which example I would choose for the long term.. #biodiversity #miyawkimethod #ecosystem #ecosystemrestoration #nature #olivetree #olivegrove #nature #naturebasedsolutions #restoration #reforestation #gaia #permaculture #syntropic #biodynamic #organic
