Hope Sail-Powered Cargo Ships Scale Up A new, much-bigger addition to the world's fleet of hybrid sail/diesel-powered commercial cargo ships.
Geothermal vs Ground-Source Energy: What’s the Difference? Lots of naturally-occurring (low-carbon) heat is underground. Using it to generate electricity and provide heat for our buildings and processes is becoming more common.
Carbon Ecosystem Engineering: How Animals Positively Shape Their Environments Animal ecosystem engineers modulate the availability of resources to themselves and other species by improving ecosystem structure and function, in the process consistently sequestering and storing more carbon.
Hope EVs Deliver Lowest Lifecycle Carbon Footprint Everywhere Cradle-to-grave GHG emissions of light duty electric vehicles are lower than all forms of their internal combustion-engined equivalents, no matter the region
Materials Cooler Cement Changing the surface microstructure of cement reduces concrete's contribution to global warming by keeping structures cooler
Hope One New Way of Making Low-carbon Cement Even cement production can be electrified, for a 90% reduction in GHGs
Hope Tidal Turbine Bearings and Seals Critical components for successful long-term tidal turbine operation reach a major reliability milestone.
Wind Bladeless Wind Generators A Spanish company is developing wind generators that exploit the vortex-shedding effect. The tapered towers have no rotating parts.
Historical Perspective Oil Shocks and Microchips How buildings learned to stop wasting and start thinking
Hope Reusable Hospital Isolation Gowns Radically reducing the biggest source of hospital waste for GHG and cost reductions
Solar AI Data Centre Powered by Renewables and Used BEV Batteries Synergistic pairing of renewable energy with used BEV batteries to power AI data centre standalone microgrid.
Climate Change Misinformation, Disinformation, Malinformation, and Distrust of Climate Science Misinformation, disinformation and malinformation are forms of rampant pollution of the information ecosystem. This pollution is toxic, promoting distrust in science, and holding back efforts to combat climate change.
Greenhouse Gases Sand Batteries A company in Finland has brought on line a high-temperature heat storage installation, using crushed local soapstone, to store off-peak and renewable energy for use during peak demand periods
water New Desalination Technology Australian researchers have developed a new desalination process that uses less energy than phase change and requires less maintenance than reverse osmosis.
Greenhouse Gases Efficiency Gains via Electrification, or Why We Should Electrify Everything We Can Decarbonizing the economy by electrifying everything in it will mean we need less total energy.
Hope Storing Energy from Renewables and/or Waste Heat for Industrial Processes System to store renewable energy as high-temperature heat for industrial processes
Materials Steel Steel is one of the pillars of modern civilization but its production emits far more CO2 than the aviation industry. Material substitutes for steel simply don’t exist on the kind of scale needed. Reducing the carbon impact of steel production faces major technical and economic challenges.
Hope Extracting Water from Desert Air with Bio-inspired Materials Getting water from desert air, like a frog
Solar Covering Canals with Solar PV A pilot project to reduce evaporation and generate renewable electricity by covering irrigation canals with solar PV has completed its first phase.
How-to Resilience Borne of Disaster After experiencing disasters, many places around the world are rebuilding to be more resilient in future. We can learn from the experience of others how to assess our local hazards and risks and upgrade our infrastructure, so as to lessen the damage from future events.
Hope Printed Circuit Boards Made from Leaves and Pill Coating Researchers have invented printed circuit boards made from leaves of magnolia trees.
