The New Solar Frontier

Perovskite-silicon tandem cells are crossing the 30% efficiency line in labs, while durability barriers are steadily falling with better encapsulation and testing. A startup founder told us their roll-to-roll pilot produced modules during a humid summer without delamination. Where would you deploy these first: warehouses, schools, or community solar canopies?

Storage That Scales

Iron-Air and Sodium-Ion Step Into the Spotlight

Iron-air systems promise multi-day storage by rusting and de-rusting iron—cheap materials for long-duration resilience. Sodium-ion cuts costs by avoiding scarcer elements, promising solid performance for grid and mobility. A rural co-op manager told us recycling pathways mattered most for member trust. What performance metrics matter to you—cost, safety, or footprint?

Flow Batteries for Rugged Resilience

Flow batteries separate power and energy in tanks of liquid electrolytes, scaling affordably and improving fire safety. Vanadium and organic chemistries ride through deep cycles without fatigue, perfect for microgrids and schools. Have you piloted one? Share how permitting, training, and maintenance actually went beyond the glossy brochures.

Thermal Storage: Banking Heat and Cold

From molten salts at solar towers to sand silos and phase-change materials in buildings, thermal storage is quietly slashing peaks. A bakery we visited stores heat off-peak, then bakes at dawn with lower bills and steadier ovens. Building managers, want templates and specs? Subscribe, and we’ll send our retrofit checklist.

PEM and alkaline electrolyzers are scaling fast, with gigafactories trimming capex and uptime rising through smarter stacks and membranes. Projects pair with curtailed solar to improve economics while recycling water and capturing oxygen. What siting constraints—water supply, grid interconnection, or policy credits—most influence your roadmap? Tell us below.

Hydrogen, Ammonia, and E-Fuels

Green steel trials feed hydrogen into direct reduction furnaces, while shipping pilots test ammonia as a carbon-free carrier. Ports are mapping bunkering corridors and training crews to new safety codes. Are you in maritime, logistics, or heavy industry? Share the obstacles you face and what would unlock your first real purchase order.

Smarter Grids and Virtual Power Plants

Virtual power plants aggregate thermostats, water heaters, home batteries, and EVs to shave peaks and stabilize frequency. During a heatwave, one VPP we tracked kept lights on while residents earned bill credits and texts explained each dispatch. How should programs reward low-income participants fairly? We want your ideas.

Heat for Homes and Cities

A family in a drafty bungalow replaced their old furnace with a cold-climate heat pump, then messaged us: the quiet hum felt like a library. Paired with air sealing, their winter bills dropped dramatically. Installers say training is scaling fast. What would help you switch—financing, contractor lists, or neighbor referrals?

Heat for Homes and Cities

Shallow ground loops share heat across neighborhoods, while enhanced geothermal drills deeper, tapping steady baseload. Former oilfield crews bring invaluable drilling expertise to this new chapter. A campus project now heats labs with steady geothermal, cutting noise and emissions. Curious about seismicity safeguards? Ask, and we’ll invite experts to reply.

Heat for Homes and Cities

Ambient-temperature networks move heat like data, enabling buildings to share surplus through heat pumps. Data centers donate waste heat to pools and housing, turning liabilities into community assets. Want case studies or design details? Comment with your city, and we’ll send a roundup of comparable climates and systems.

Policy, Finance, and People Power

Community solar shares, cooperative wind, and shared savings align benefits with the people hosting projects. A farmer-led co-op negotiated fair land leases and habitat buffers, then sold out subscriptions in a weekend. Community leaders, how do you ensure equity from day one? Share your playbook and pitfalls.
