本书描述了一种大胆的新思路，用以实现2050年温室气体减排目标：利用太阳能光伏电力制取氢气，使其作为交通运输系统的主要能源载体和主要储能机制，以平抑可再生电力随时间产生的波动，从而消除发电带来的全部温室气体排放。我们表明，这样的太阳能-氢能系统（SHES）无需任何政府支持即可实现可负担的成本。私营工业界在 SHES 上的投资能够获得强劲的回报。
This book describes one bold new approach to achieve the 2050 GHG reduction goal by using solar photovoltaic energy to generate hydrogen gas as the main energy carrier for the transportation system and the main energy storage mechanism to smooth out renewable electricity fluctuations over time, which would eliminate all GHG emissions from generating electricity. We show that such Solar-Hydrogen Energy Systems (SHES) will be affordable without any government support. Private industry can make a robust return on their investments in SHES’s.
