We synthesized a tungsten titanium carbide (W2TiC2) MXene. By loading cobalt onto the surface of W2TiC2, we developed an effective and stable catalyst for an alkaline hydrogen evolution reaction. The catalyst exhibited a small overpotential of 63 mV at 10 mA/cm2 and a low Tafel slope of 44.3 mV/dec. At high current density of 100 mA/cm2 and 1000 mA/cm2, low overpotentials of 191 mV and 408 mV were achieved, outperforming commercial Pt/C electrodes. Under both current ranges, our catalyst exhibited excellent stability of 500 h at 10 mA/cm2 and for 100 h at 1000 mA/cm2 without any degradation. In flow cell tests, by pairing with Ni foam, our catalyst required much lower cell voltage than commercial Ni foam Pt/C and maintained ̃100% H2 faradaic efficiency over 15 h of continuous tests from 50 to 400 mA/cm2.

An energy storage system converts variable renewable electricity (VRE) to continuous heat at over 1000° C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. An array of bricks incorporating internal radiation cavities is directly heated by thermal radiation. The cavities facilitate rapid, uniform heating via reradiation. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. Gas flows through structured pathways within the array, delivering heat which may be used for processes including calcination, hydrogen electrolysis, steam generation, and thermal power generation and cogeneration. Groups of thermal storage arrays may be controlled and operated at high temperatures without thermal runaway via deep-discharge sequencing. Forecast-based control enables continuous, year-round heat supply using current and advance information of weather and VRE availability. High-voltage DC power conversion and distribution circuitry improves the efficiency of VRE power transfer into the system.

【課題】水電解スタックに意図しない劣化が生じても、複数の水電解スタックに対して適切な電力配分を行う。【解決手段】水電解システムは、複数の水電解スタックと、複数の水電解スタックのそれぞれに直流電流を供給する電源と、電源の動作を制御する制御装置と、を備え、制御装置は、複数の水電解スタックのそれぞれについて、水電解スタックの電流および電圧の計測値に基づいて、水電解スタックの入力電流の変化に対する出力電圧の応答特性を近似した特性モデルを所定期間ごとに算出することにより、複数の特性モデルを生成し、少なくとも２つの特性モデルの特性差に基づいて、水電解スタックの劣化度を推定し、劣化度に基づいて、水電解スタックに流す電流を制御する。【選択図】図１
