Proton Power's subsidiary, Proton Motor Fuel Cell, has signed a co-operation agreement with Modl to provide interruption-free and energy efficient storage for the stationary power supply market. Both partners will offer complete solutions for Uninterrupted Power Supply (UPS) and grid shaving applications based on Proton Motors' hydrogen fuel cell technology and Modl's product portfolio.The development is particularly relevant in Germany, given the recent shutdown of nuclear power stations and the growing reliance on renewable energy supplies which are intermittent requiring increased storage, the firm said. Modl, Proton Motor's sales partner in southern Germany, has many years' experience in the market and a large customer base for stationary power supply.Thomas Melczer, Director of Business Development said: "Partnering with Modl, the leading supplier of intelligent power system solutions, demonstrates that Proton Motor is a key supplier of hydrogen-based fuel cell technology in Germany. "The market for energy efficient backup power supply is expected to experience significant growth in the near future, as expected power outages and power supply shortages become the focus of operators of mission critical applications such as hospitals, data centres, telecommunications companies and airports."The products are specially engineered to provide a long period of backup power of over five hours, and will range from five to 120 kilowatts. The first joint projects are underway.The share price rose 6.67% to 2.00p by 09:58.NR
