Digital Power Optimization, Inc.
Digital Power Optimization (DPO) is a New York-based energy services company that builds and operates 'power-first' flexible data centers at renewable power plants. Its on-site data centers - running bitcoin mining and AI workloads - consume electricity only when it is curtailed, wasted, or undervalued, then curtail during peak demand so power can be sold back to the grid. The model lets hydro, wind, and other generators capture over $100/MWh from otherwise stranded power while helping stabilize the grid.
280 Earth
280 Earth is a climate-tech company that removes carbon dioxide permanently from the ambient air using a modular Direct Air Capture (DAC) system spun out of Alphabet's X, The Moonshot Factory. Its continuous-flow process uses a proprietary sorbent, off-the-shelf industrial equipment and low-grade waste heat or clean electricity to pull CO2 - and fresh water - out of the atmosphere at low energy cost. Its first plant in The Dalles, Oregon began operating in May 2024 and is designed to scale from hundreds to more than 20,000 tons of CO2 removed per year. The company's name references 280 parts per million, the pre-industrial atmospheric CO2 concentration it aims to help restore.
Gregg Semler
Gregg Semler is the founder and CEO of InPipe Energy, a Portland-based company that generates clean, around-the-clock electricity from the water already flowing through municipal pipelines. A serial clean-energy entrepreneur since 2000, he previously led PolyFuel, ClearEdge Power, and Lucid Energy, and spent years as a venture investor in the sustainable economy. His pitch is contrarian: instead of covering the planet with solar panels and batteries, harvest the predictable, weather-proof energy hiding in the millions of miles of pressurized pipe that move our drinking water.
