MIT Energy Initiative conference highlights storage research priorities
At the MIT Energy Initiative conference last week, engineers, investors and policy analysts crowded the room, all trying to make sense of a power system that’s suddenly more fluid. The buzz wasn’t just about new batteries or molten-salt tanks - it was about what those tools actually do. Storage, it turns out, isn’t one thing.
One project might need to smooth out the grid, another to shave peak demand, a third to soak up solar spikes. No single breakthrough seems enough; the real question is how much value each service adds. Panels kept circling back to a simple dilemma: should we bet on cost, on how long a device can discharge, or on how fast it reacts?
That nuance feels crucial, because the market rewards whatever outcome you can prove works, which means the “best” technology keeps shifting. I’m curious how Google’s commercial lead for advanced energy investments will weigh in - he’ll probably argue that the right storage choice depends on which service you care about most.
"At the end of the day, storage provides a service, and the type of technology that you need is a function of the service that you value the most," said Nestor Sepulveda, commercial lead for advanced energy investments and partnerships at Google. "I don't think there is one winner-takes-all type of market here." Another panel explored sustainable fuels that could help decarbonize hard-to-electrify sectors like aviation, shipping, and long-haul trucking. Randall Field, MITEI's director of research, noted that sustainably produced drop-in fuels -- fuels that are largely compatible with existing engines -- "could eliminate potentially trillions of dollars of cost for fleet replacement and for infrastructure build-out, while also helping us to accelerate the rate of decarbonization of the transportation sectors." Erik G.
Birkerts is the chief growth officer of LanzaJet, which produces a drop-in, high-energy-density aviation fuel derived from agricultural residue and other waste carbon sources. "The key to driving broad sustainable aviation fuel adoption is solving both the supply-side challenge through more production and the demand-side hurdle by reducing costs," he said. "We think a good policy framework [for sustainable fuels] would be something that is technology-neutral, does not exclude any pathways to produce, is based on life cycle accounting practices, and on market mechanisms," said Veronica L.
Robertson, energy products technology portfolio manager at ExxonMobil. MITEI plans a major expansion of its research on sustainable fuels, announcing a two-year study, "The future of fuels: Pathways to sustainable transportation," starting in early 2026. According to Field, the study will analyze and assess biofuels and e-fuels.

Desirée Plata wrapped up the day by reminding everyone that real change needs people to show up. More than 150 scholars, industry reps and government officials packed into Cambridge - a sign the topic is pulling a lot of interest. Still, the agenda left a lot hanging.
Nestor Sepulveda from Google argued that storage is really a service, and the right tech hinges on which service you value most. He also warned there’s no single “winner-takes-all” answer, a point that seemed to click with the audience. The talks sketched out research priorities, but the exact road ahead stayed fuzzy.
Can the new storage ideas actually satisfy the range of grid services we outlined? The conversation hinted we need more flexible research plans, yet nobody spelled out how the money would flow. Most left thinking progress will depend on matching technology to specific grid needs rather than chasing a universal fix.
It’s still unclear which solutions will scale, so we’ll probably need more collaboration to test the ideas. In short, the meeting painted storage as a menu of options, not a single, set path.

Common Questions Answered
What did Nestor Sepulveda of Google say about the role of storage technology at the MIT Energy Initiative conference?
Sepulveda emphasized that storage provides a service and the optimal technology depends on the specific service valued most. He argued there is no single "winner‑takes‑all" solution, highlighting the need to match technology to application.
Which hard‑to‑electrify sectors were highlighted for sustainable fuel research during the conference?
The conference panel identified aviation, shipping, and long‑haul trucking as sectors where sustainable fuels could help decarbonize. These industries were noted for their difficulty to electrify directly, making alternative fuels a priority.
How many participants attended the MIT Energy Initiative conference in Cambridge, and what groups did they represent?
Over 150 scholars, industry representatives, and government officials gathered in Cambridge for the event. The diverse attendance reflected broad interest across academia, the private sector, and policy circles.
What are the three primary applications of energy storage discussed at the MIT Energy Initiative conference?
The conference highlighted grid balancing, peak shaving, and renewable integration as key storage applications. Each use case requires different technology characteristics to meet distinct service needs.
