Japan

Main findings

2050 projections of power and industrial high temperature heating sectors:

• Projected no-action emissions based on current energy mix: 639 MtCO2e /year+
• Maximum mitigation potential: 639 MtCO2e /year
• Most important needle-movers are onshore wind, Open field PV, Battery Storage, HVDC and Ammonia Storage.
• Average cost of achieving zero emissions with only domestic measures is USD 53/tCO2e.
• he cost of building a net zero system can be reduced by up to 26% with international collaboration. Green electricity trade and a combination of battery and ammonia storage are key for this cost reduction.
• nternational collaboration can be extremely effective for Japan to eliminate the sharp increase in costs towards the zero emissions point.
  +Emissions are the annualized value for a 30-year project starting in 2050 (i.e., divided by 30 from the total project emissions)
