Synthetic fuel at aviation scale will take a different kind of plant. @BillGates and Lydian CEO Joe Rodden explain how smaller facilities designed for replication and mass production could help get there.

Batteries are great, until you need to cross an ocean. Eric Toone explains why energy density keeps liquid fuels at the center of long-haul flight, and how the @traveloneworld BEV Fund is backing better ways to make them.

Algae could help fuel the future of flight. Our founder @BillGates shares how Phykion is engineering oil-rich algae to produce more of the feedstock SAF needs—using sunlight, CO2, seawater, and existing HEFA refining infrastructure.

Big energy companies can start as small ideas in labs: bth-energy.com/47UwGTT The BE Fellows program helps early-stage builders move faster with up to $500k in R&D support, hands-on technical guidance, mentorship, and access to a global network. Cohort 7 applications are open through November 2.

Long-haul flight still depends on fossil-based liquid fuels. The opportunity is to make better ones that can compete on cost. Phykion is using algae to do exactly that. Rodi Guidero explains why making the economics work is key.

Cars can electrify. Long-haul aviation is a much tougher problem. Our founder @BillGates on why better liquid fuels will be essential, and what it will take to make them without adding more CO2 to the atmosphere.

Breakthrough Energy Fellow alum Cemvision is turning steel and aluminum industry byproducts into cement designed to compete with traditional cement on price. Building a climate technology with that kind of potential? Applications for the next cohort of Breakthrough Energy Fellows are now open: bth-energy.com/4xNgoH6

A strong showing from our portfolio on this year’s “50 by 2050” list from @congruentvc and @SiliconVlyBank: @pivotbio, @Mill, @WeaveGrid, @VEIR_Grid, @tsconductorcorp, @heronpower, @FormEnergyInc, @CFS_energy, @RedwoodMat, Lydian, @luxwall_inc, @rondoenergy, Koloma, @Electric_H2, Electra, and @antoraenergy. Proud to see so many teams we back recognized for building technologies with the potential to reshape major industries and infrastructure. bth-energy.com/46LwaqV

@heartaerospace just unveiled the ES-36, a 36-seat hybrid-electric aircraft built to make regional flight more efficient. @flyjsx has already signed for up to 100 aircraft—a strong signal that better aircraft economics can open up more routes and more convenient travel.

Our Breakthrough Energy Fellows program is now 100+ companies strong. Today, we’re proud to share Cohort 6 of Breakthrough Energy Fellows, bringing 40 Fellows across 21 companies and 9 countries into the program—expanding the global pipeline of builders working on the next generation of energy and industry. bth-energy.com/4hEDIlk
