At Fuse, we're building a fully integrated energy company, from developing solar, wind, and hydrogen to power trading & distributed energy installations. We sell directly to energy consumers, cutting out the middleman to reduce costs and pass on savings to customers.
But we’re not stopping there.
We’re also building the Energy Network: a decentralised network of smart devices where users get rewarded in Energy Dollars for electrifying their homes, shifting usage to off-peak hours, and helping balance the grid. The energy network helps the grid achieve energy stability, a crucial requirement for growth of AI data centers and energy intensive industries.
