  • The system eliminates the need for network infrastructure improvements by using a phosphoric acid-doped membrane and a patented bipolar plate technology, reducing costs and enhancing efficiency.
  • HyWatts claims the system can provide energy to a community of 50 off-grid homes at $0.12/kWh, with 1 kg of hydrogen covering a US household's energy needs for a day.
  • Tested for industrial hydrogen supply, the system offers energy at a marginal cost of $2.38/kg, showcasing its versatility and cost-effectiveness in various applications.
US-based startup HyWatts has revealed its innovative Powerplant-in-a-Box system, a groundbreaking high-temperature proton exchange membrane (HTPEM) fuel cell. This system not only generates electricity from hydrogen but can also operate as an electrolyzer, producing hydrogen from electricity. The design aims to address energy supply challenges in remote areas, reducing the reliance on extensive network infrastructure upgrades. Unlike traditional fuel cells, HyWatts' system utilizes a phosphoric acid-doped membrane that eliminates the need for constant humidification, offering a wider operating temperature range and simplifying system components. The company's proprietary bipolar plate (BPP) technology further enhances efficiency by enabling direct air cooling for large-scale systems, streamlining the power generation process. HyWatts estimates that for a small community of 50 homes, the system can deliver energy at an attractive rate of $0.12/kWh, with just 1 kg of hydrogen sufficient to power a US household for a day. Additionally, the system's versatility was demonstrated in industrial applications, providing hydrogen supply at a competitive cost of $2.38/kg. This development heralds a new era in renewable energy solutions, offering cost-effective and reliable energy access for off-grid locations and industrial processes.
