Empowering innovators to build the future of energy

[Breakthrough Energy @Breakthrough]

Energy powers prosperity.

The innovation pipeline is stronger than ever. As founders, investors, and partners gather in Houston for the BEV Investor Summit, we’ll focus on what it takes to scale companies that can deliver affordable, reliable, clean energy across the world’s largest industries.

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.

From BE Fellow to breaking ground on a U.S. steel facility. @HerthaMetals started in our first cohort. Cohort 7 applications are open now: https://t.co/PdOFvJWS1d

SAF is only one piece of the liquid fuels opportunity.

Our Executive Director Rodi Guidero looks at how technologies like natural hydrogen, cheaper electrolysis, and new fuel pathways—and hard-earned expertise from oil and gas—can help build the next generation of fuels.

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.

Hard markets make better companies.

Our CIO @carmichaelvc on how the Lydian and Phykion teams are building for aviation, and why the right partners can change the trajectory.

25 MW. Up to 50 hours. @fourthpowerinc is building thermal batteries designed to keep reliable power flowing when demand spikes.

Its first demonstration system is now under construction in Massachusetts.

@CFS_energy is one of @FastCompany’s 6 Next Big Things in Sustainability and Energy for 2026.

With high-temperature superconducting magnets, CFS is helping make smaller, lower-cost fusion systems possible.

Big energy companies can start as small ideas in labs: https://t.co/hhTglCu9ku

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.

[Breakthrough Energy @Breakthrough]

SAF won’t win on chemistry alone. It has to win on cost.

Our CTO Eric Toone looks at how Lydian and Phykion—the first investments from our oneworld BEV Fund—are attacking that challenge from two very different directions, and what it will take to compete at aviation scale.

Nearly half of the companies on @techreview's Climate Tech Companies to Watch list are backed by Breakthrough.

@BrimstoneEnergy, @FormEnergyInc, @fervoenergy, and Energy Dome. Four builders taking on some of energy’s hardest problems.

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.

[Breakthrough Energy @Breakthrough]

Better flight is going to take new fuels and aircraft. But some progress doesn’t have to wait.

Small route changes on a small share of flights could avoid most of the heat-trapping clouds planes leave behind, using today’s aircraft and fuels. @BillGates explains how.

[Breakthrough Energy @Breakthrough]

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 @Breakthrough]

AI needs a lot more power, and better ways to move it. @VEIR_Grid just raised a $110M Series C to scale superconducting systems designed to beat conventional power delivery on space, materials, and cost.

[Breakthrough Energy @Breakthrough]

@antoraenergy is bringing 5.8 GWh of thermal storage to Pratt, Kansas, delivering affordable, reliable, clean energy to local industry and supporting 100+ jobs.

With internships, scholarships, and local hiring built in, this is energy infrastructure designed to strengthen the community around it.

[Breakthrough Energy @Breakthrough]

OpenGrid is here. The new initiative from the @linuxfoundation grew from @BillGates’ push for better tools to guide energy infrastructure decisions—and was incubated through our GRIDS program.

Reliable electricity enables health, jobs, and economic growth. OpenGrid is bringing open-source innovation to grid planning so more countries can build the infrastructure to deliver it.

$200M more behind stellarator fusion. We’re excited to be co-leading @typeoneenergy's Series B as the company moves toward commercializing fusion.

@Siemens_Energy Ventures joins a broad syndicate of investors, adding industrial muscle as Type One advances Project Infinity and works to turn fusion into affordable, reliable, clean power.

A major unlock for better lithium production. @Lilac_Solutions and @lake_resources Kachi project secured South America’s first commercial-scale DLE permit with brine reinjection—advancing a path to more critical-material supply with less land and water.

@Primark is committing to @circ_earth's recycled polyester through a new multi-year agreement beginning in 2029.

That demand will help support Circ’s first industrial-scale facility in France—and move textile-to-textile recycling into real manufacturing.
