An increase of nuclear electricity generation capacity from the current level of 52 GW to 70 GW by 2025: – All else equal, this increase would boost the share of nuclear in primary energy to 5.7%, from the current level of 4%. 2. Achieve 20% of primary energy consumption from non-fossil fuel by 2025. 1. However, it has not capped the consumption of coal. This opens the option of reducing other fuels to reach the 20% target. • These targets could curtail a strong push toward increased gas consumption. • Carbon price not high enough to incentivise coal to gas switching. • Higher gas prices may lead to a slower shift from the more competitive coal to gas. • Under existing conditions, the maximum technical potential to switch from coal to gas in electricity generation in China is only ca. 9% of current coal generation level. 10 US success Electricity generation mix 6,000 100 5,500 90 5,000 80 70 4,500 60 4,000 50 3,500 40 30 3,000 20 % of total generation 2,500 US CO2 emissions, mn tCO2eq 10 2,000 0 1990 1993 1996 1999 2002 2005 2008 2011 2014 2017 2020 2023 2026 2029 1990 1992 1994 1996 1998 2000 2002 2004 2006 2008 2010 2012 2014 2016 2018 Historic CO2 emissions Coal Natural gas Linear trend (2007-30) Petroleum Non-carbon generation Biden's 2030 climate target Source: EIA 11 But a lot more to be done • US President Biden’s recent climate target (50% GHG emissions reduction by 2030 relative to 2005) is very ambitious • Requires enormous investment in all types of clean technologies and low carbon energy sources. • To put this target in the historic context of US CO2 emissions trend: • since 2007 till 2019 emissions have been decreasing at an average pace of 67 mn tCO2eq/year. • This past trend indeed considers the effect of switching from coal to gas in the power sector, given the shale gas revolution. • However, to achieve Biden’s new climate target, the rate of decline in CO2 emission would need to be 184 mn tCOeq/year between now and 2030. This is almost three times the rate of decrease that the US achieved in the recent past. • The role of gas in this journey to meet the newly announced target will clearly be more important than ever. 12 Thank you!
