2 Motivation for energy storage increasing variable generation fluctuating demand (as it always was)

3 What does the transition to wind and solar mean? Generation Grids Power Storage Wind/Solar-to-Power Gas Flexibility! Heat Power-to-Power Gas-to-Power/Heat Power-to-Gas Coal-to-Power/Heat Demand Residential Mobility Industry Power-to-Heat

4 Its useless to estimate the energy storage demand? However, the demand will be high! Installed Storage Capacity [GWh] System Level Energy Storage Demand Capacity expansion until 2030 When and how much increase of renewables? decommissioning of conventional generation? grid expansion? decentralization? demand respond management E-Mobility with batteries? E-Mobility with fuel cells? Synergies with Industry? and what about the influence of commodity 4 (1) BCG, (2) Imperial College (3) VDE-ETG (4) TUM-FfE

5 Example: Energy transition Germany Installed generation capacity approaching 400 GW? Gross power consumption (TWh) 550 TWh 3,4% RE 634 TWh (33,4 TWh net export) 25% RE 0 70,6 4,7 13,7 580 TWh 100% RE * Future 2050 theoretical approach Wind and solar generation quadruples installed capacity 1% curtailment requires additional 3-4 GW RE Source: BMWi, Arbeitsgruppe Erneuerbare Energien-Statistik Assumptions scenario future: Power consumption is stagnant and corresponds the RE generated. Full load hours of wind + sun = 1,600 h Base load RE have a limited potential. RE: Renewable Energy conv. generation base load RE sun+wind *) data 2012

20 Prerequisites for Energy Storage Storages represent a fourth element in the energy system = they are neither generation, nor network, nor consumers. The regulatory framework for storages should be technology open. = Power-to-Power, Power-to-Gas, Power-to-Heat = part of the competitive market Reduction of investment costs = cost reduction Storages should be relieved from grid tariffs, charges and/or taxes = no burdens for innovation prior economic efficiency Direct marketing = customer interest

22 Takeaways (1) Power to Gas is part of the transition to renewable energy. For many customers it is the only applicable connection to renewable energy. (2) Power to Gas connects to very different markets such as heating or mobility and offers flexibility to the electricity grid. (3) Power to Gas opens up a sustainable long-term perspective for the gas infrastructure. (4) The technology is ready for the market. Are you? (5) If you think Power to Gas is too expensive, you may come to a different conclusion looking at the alternatives for abating carbon emissions.
