Norwegian Shipbuilders Turning to Battery Power
How much CO2 per kWh does it come to when you divide the total CO2 footprint of the battery manufacture and materials over the charge cycles of the battery?<p>edit: One study[1] indicates the figures are 150-200 kg CO2 equivalent per 1 kWh of battery. So for 1000 cycle durability, that would make 150-200 g per kWh even without counting the CO2 effects of charging power[2]. Diesel engines emit 250 g per kWh[3] of energy produced. Doesn't sound like such a great tradeoff.<p>[1] <a href="http://www.ivl.se/download/18.5922281715bdaebede9559/1496046218976/C243+The+life+cycle+energy+consumption+and+CO2+emissions+from+lithium+ion+batteries+.pdf" rel="nofollow">http://www.ivl.se/download/18.5922281715bdaebede9559/1496046...</a><p>[2] Even if Norway produces low emission hydro electricity, the same electricity could be used to displace dirty power if exported to Denmark etc.<p>[3] <a href="https://www.engineeringtoolbox.com/co2-emission-fuels-d_1085.html" rel="nofollow">https://www.engineeringtoolbox.com/co2-emission-fuels-d_1085...</a>
