Breakthrough Energy

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.

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.

@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.

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.

@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.

A new pilot with @RWE_AG Americas will put @heronpower's grid hardware to work at utility scale.

Better power electronics can make it simpler and more economical to add the solar and storage a growing grid needs.

@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.

First power. First in the world. @fervoenergy is now sending electricity from Cape Station to the grid—the first utility-scale enhanced geothermal system to reach this milestone. Congrats to the team.

Fusion’s next challenge is commercial viability.

Across our portfolio, @CFS_energy, @_Pacific_Fusion, @typeoneenergy, @xcimerenergy, @Energy_Zap, and BE Fellow @MarathonFusion are advancing different paths to make fusion practical, scalable, and competitive in the real world.

A new facility in Bedford, Massachusetts is now home to @fourthpowerinc’s first full-scale energy storage demonstration.

The goal: multi-day storage that can beat gas peakers on cost and deliver affordable, reliable, clean power when the grid needs it most.
