The U.S. energy storage boom has a chemistry problem. Lithium-ion batteries — originally built for phones and laptops — now power massive grid installations. They’re fast, dense, and increasingly cheap. But they’re also flammable, degrade over time, and struggle with the kind of long-duration storage a renewable-powered grid needs. Fire hazards in California. Costly replacements in Texas. Even in federally backed programs, developers face rising insurance premiums and safety

Greennex sees  a contradiction at the heart of climate investing. While the world demands rapid deployment of sustainable infrastructure, the capital behind it often behaves like it’s chasing short-term exits. Climate infrastructure — particularly at the early stage — needs something different: conviction, time, and tolerance for ambiguity. Few investors embrace this ethos as clearly as Vinod Khosla , founder of Khosla Ventures , one of the earliest and most vocal champions o

A Conversation with Sonam Velani, Co-Founder of Streetlife Ventures Greennex sees  an inflection point in climate capital. As the market rushes toward gigaprojects and frontier tech, some of the most deployable climate innovations are happening on a different scale — at the city level. Rooftops, sidewalks, public housing, and logistics curbsides have become the new battlegrounds for emissions reductions, equity, and adaptation. But this shift demands a different kind of ventu

By Greennex Frontier ⚡ The Grid Flexibility No One’s Using Across the U.S., grid operators are searching for new ways to manage peaks, reduce emissions, and ride through weather shocks. Yet one of the most abundant — and overlooked — flexibility resources is already wired into the buildings we live in: thermal systems. From HVAC to water heaters, America’s buildings consume more energy for heating and cooling than for lighting or appliances. But while batteries and EVs domina

By Greennex Frontier The U.S. is racing to decarbonize its grid, but its energy storage strategy remains uneven. Billions have been poured into battery incentives through the Inflation Reduction Act, and state-level mandates are multiplying. Yet across the country, utilities and developers still struggle to turn storage into a dispatchable, bankable resource. Storage assets exist — but many remain under-optimized. The missing link isn’t hardware. It’s orchestration. Without i

By Greennex Frontier Across the U.S., commercial buildings account for nearly 40% of total energy consumption — and yet, most remain digitally blind  to how their energy is used. Energy bills arrive monthly, HVAC systems are programmed with guesswork, and “efficiency” often means replacing lightbulbs, not optimizing real-time behavior. Even as ESG mandates, peak-demand charges, and carbon pricing accelerate, most property operators and industrial managers still lack the tools

By Greennex Frontier The U.S. grid has become a national liability. Aging transformers, overloaded substations, and an outdated monitoring architecture have left utilities vulnerable to fires, blackouts, and multi-billion-dollar maintenance backlogs. While federal programs like the Grid Resilience and Innovation Partnerships (GRIP) pump billions into modernization, much of the investment still favors large capital upgrades over precision intelligence. The problem isn’t just h

By Greennex Frontier The U.S. Offshore Wind Problem: Big Targets, Bigger Risks The U.S. has set ambitious goals for offshore wind — 30 GW by 2030, multi-state procurement targets, billions in federal support — but real-world execution tells a different story. Cancelled contracts, rising capex, unbankable PPAs, and supply chain breakdowns continue to plague the sector. Beneath it all lies a deeper structural gap: a lack of visibility. Developers are bidding on leases and proje

By Greennex Frontier The Big Grid, Fragmented Logic Across the U.S., the energy transition is speeding up — but the systems managing it are struggling to keep up. Distributed renewables are rising. EVs are multiplying. Smart thermostats and batteries are everywhere. Yet most utilities still rely on slow, one-directional control systems , designed for centralized fossil generation, not dynamic, distributed supply. The result is a grid where billions of dollars of flexibility p

By Greennex Frontier As U.S. corporations chase net-zero targets, a critical bottleneck remains unresolved: how to decarbonize high-demand facilities like data centers, logistics hubs, and factories — especially across multiple countries. Rooftop solar and PPAs are now common tools, but the deployment process remains fragmented. Most companies face inconsistent permitting, disjointed project development, and a lack of lifecycle visibility. In Asia, one company is quietly engi

By Greennex Frontier For decades, the U.S. power system has faced three persistent structural challenges: • Vulnerability of centralized grids : Extreme weather has led to frequent large-scale blackouts in California, Texas, and Puerto Rico. • Uneven infrastructure distribution : Rural, tribal, and off-grid communities remain underserved by clean energy access. • Deployment barriers for microgrids : Despite increasing policy support, projects often struggle with high upfront

Greennex Insight In the U.S., the energy transition has largely focused on generation — solar, wind, batteries, EVs. But one critical piece remains stuck in the last century: the retail electricity experience. Despite billions invested in hardware and infrastructure, most American households still buy power the same way they did 30 years ago — through static tariffs, fixed-rate contracts, and little visibility into real-time cost, carbon, or control. In Northern Europe, a ver

Greennex Insight For decades, U.S. grid operators have faced the same bottleneck: renewable energy is growing fast, but the system’s ability to manage its volatility and maintain real-time balance is not. Despite massive public and private investment in storage, transmission, and smart meter deployments, America still lacks a working model that treats demand-side flexibility as dispatchable infrastructure . Europe, however, may be a few steps ahead — and one Dutch company is

Greennex Insight In the U.S., residential distributed energy is scaling fast — rooftop solar, EV chargers, heat pumps, batteries. But one thing remains stubbornly unsolved: how to turn all that capacity into something the grid can actually use . Despite years of smart meter rollouts, demand response pilots, and policy nudges, there is still no dominant interface that lets the average home behave like a grid asset — responsive, intelligent, and valuable. In Germany, one startu

Greennex Insight In the U.S., the electrification boom is colliding with a coordination crisis. Cities are installing EV chargers faster than substations can keep up. Rooftop solar is booming, but excess generation is straining local networks. Smart meters are widespread, but grid flexibility is still mostly theoretical. Utilities are being asked to shift from supply managers to system orchestrators — yet many lack the tools, visibility, or market signals  to make it real. Am
