About GridBlock

GridBlock is an innovative energy router that dynamically manages the flow of energy between multiple sources and loads and is able to create and operate a self-contained microgrid. GridBlock packetizes and routes electrical energy with isolation and high accuracy to serve AC or DC systems seamlessly. The precision technology enables a bidirectional power flow on multiple ports or channels concurrently, bringing the flexibility and control of Internet routers and switches to the electrical grid. Increasingly, electrical installations require smart integration of EV or e-truck charging, battery storage, solar panels, and critical loads, with custom design and build for each location adding to the cost of implementation. GridBlock simplifies all of this with a flexible, software-defined, modular solution that can manage a wide variety of end-use configurations and applications.

GridBlock is part of Endeavour, a purpose-built company taking on global challenges to guarantee renewable energy and clean water to everyone, everywhere by decentralizing infrastructure, developing new technologies, and deploying energy, water, and waste valorization solutions that are more profitable than those that currently exist.

About GigaGrid

The GigaGrid product team is developing a plug-and-play framework for monitoring and controlling the power grid. The flagship solution, from GigaGrid is a 100% dispatchable, distributed solution that is simpler and lower cost than current solar + storage systems. It combines solar PV arrays with 2.5 hours, 5 hours, or 10 hours of modular battery storage, tri-port power converters and integrated racking. It reduces the levelized cost of energy and increases energy delivered by avoiding most of the solar clipping and roundtrip losses in conventional systems. Because the power is 100% dispatchable, it allows for grid insertion anytime, whenever it is most valuable. This dramatically improves the economics of solar energy by minimizing the reliance on energy sales during peak daylight hours when solar power can have little or no value as a grid resource.

GigaGrid is part of the Endeavour Energy ecosystem, a purpose-driven organization helping innovators to develop and launch global solutions for global challenges in the areas of energy, water, and waste to guarantee renewable energy and clean water to everyone, everywhere. Endeavour companies are made up of passionate change-makers who want to leave the world better than the way we found it. Today, Endeavour is deploying solutions that are immediately scalable and profitable, including EV charging, data center cooling, and waste to fuel systems. As we look to the future, Endeavour and GigaGrid intend to remain at the forefront of innovation, taking on grander challenges based on the needs of our clients and of local economies.
