Nuclear energy will likely be important if Japan is to achieve its aim of web zero carbon emissions by 2050, the nation’s vitality minister has informed the Monetary Occasions, saying that energy shortages this winter have helped to shift public debate over the sector.

Heavy snowfalls that introduced Japan to the brink of energy cuts final month underlined the continued want for nuclear, stated Hiroshi Kajiyama, who’s accountable for vitality in his position as minister for financial system, commerce and trade.

The feedback mirror a dramatic shake-up in Japanese coverage because it shifts again to deal with lowering emissions after a decade of counting on fossil fuels within the wake of the Fukushima nuclear catastrophe.

METI is debating a brand new vitality technique to ship Prime Minister Yoshihide Suga’s pledge of zero web emissions by 2050. However reaching this can imply large adjustments in a rustic the place 88 per cent of the vitality provide comes from fossil fuels, virtually all of them imported.

Renewables would be the prime precedence, stated Mr Kajiyama, however the limitations of Japan’s geography would require deploying all obtainable applied sciences, together with imported hydrogen, nuclear energy and carbon seize and storage.

Japan tightened its guidelines final yr on financing new coal energy stations overseas and Mr Kajiyama steered one thing comparable was seemingly at residence. “The idea is carbon seize,” he stated. “We’ll full [plants] at the moment deliberate however consistent with the pledge of zero carbon by 2050.”

Japan’s vitality prices are already a few of the highest on the earth and trade is anxious about the price of emission cuts. The automotive trade is especially alarmed by plans to part out the sale of gasoline vehicles by 2035. Akio Toyoda, Toyota chief govt, has warned there was “a threat that the automotive trade’s enterprise mannequin may collapse”.

However Mr Kajiyama stated Japan’s carmakers might be minimize off from world markets in the event that they didn’t sustain with the shift to electrification in Europe and North America. Japan needed to be a part of the worldwide motion in direction of zero carbon, he stated. “For Japan’s trade and financial system in addition to the atmosphere, it is a choice we needed to make now.”
