ITM Power will launch an enhanced Power-to-Gas product range based on a higher current density that produces 50% more hydrogen for the same stack volume in April at the 2015 Hannover Hydrogen and Fuel Cells Group Exhibit. The company will launch its new 350 kW single stack with a three stack 1MW system on show and for sale. ITM Power now has £8.686 million (US$13.2 million) of projects under contract and a further £2.496 million (US$3.8) of new projects subject to final contract negotiation. This reflects the successful conclusion of a number of negotiations and the receipt of revenue for existing projects.
Recognizing the market pull for ever larger electrolyzer systems for Power-to-Gas energy storage, ITM Power has brought to fruition two key technical initiatives in order to better meet the requirements of widespread uptake.
The first is an ability to generate up to 50% more hydrogen from the existing, self-pressurizing HGas stack platform. This is achieved by utilizing a higher current density, the key parameter in PEM stack cost reduction, helping to reduce electrolyzer capacity cost significantly.
The second is a larger stack module capable of absorbing up to 350 kW of power. The larger cell area coupled with 25% more cells per stack represents a beneficial plant simplification while permitting multi-MW installations to occupy smaller sites. The drastically reduced footprint helps alleviate siting challenges, where space is highly valued, for both energy storage and hydrogen refueling applications.
The major Power-to-Gas energy storage adoption markets today are Germany and the US. ITM Power announced two new reference plant sales in Germany to two Technical Universities; both orders are based on the HPac platform for use in Power-to-Gas applications.
The reference plant is particularly important for ITM Power in the German market and with those organizations which advise the Germany Energy Ministry. ITM Power will have four reference plant installations in Germany, including those announced here.
The market need for Power-to-gas energy storage in Germany has recently been outlined in a number of high profile reports. “Electricity Storage in the German Energy Transition”, by Agora Energiewende, identifies a requirement in Germany for electrolysis (for the Power-to-Gas, Power-to-Liquids and hydrogen mobility markets) of up to 16GW, 80GW and 130GW by the years 2023, 2033 and 2050 respectively.
This is confirmed by the report, “Power-to-Gas in Transport” (a report to the Federal Ministry of Transport and Digital Infrastructure by DLR, Berlin) which estimates the markets in Germany for Power-to-Hydrogen and Power-to-SNG, in mobility applications alone, as each reaching up to 140 TWh per annum by 2050.
