The Technology Executive Committee has just published a new technical paper on emerging climate technologies in the energy supply sector. The paper (online here) reviews a group of emerging low greenhouse gas primary energy supply and transformation and storage technologies, and attempts to answer the following three questions for each technology: 1. What is this technology, and where and how could it be useful? 2. What is this technology’s potential contribution to mitigating climate change? 3. What are the initial and ongoing social, institutional, economic and business conditions for successful uptake?
