TEMPO.CO, Tokyo - Japan, a major coal and liquefied natural gas (LNG) buyer, could be energy-independent by 2060 thanks to the expansion of solar and wind power together with storage batteries, said Jarand Rystad, chief executive of the Rystad Energy consultancy.

Japan imports most of its energy resources, with the Middle East, Australia, and the United States being its top suppliers. The government's strategy calls for a reduction in LNG and coal to under 40% of the power generation mix by 2030 from more than 60% now. But analysts say Japan is moving slower it needs to.

"Japan's mindset is that we have to import energy because we have no energy ourselves. But with the development in renewable energy technologies, I think that statement doesn't need to be true," Rystad told Reuters.

According to Rystad, Japan could be energy-sufficient by having 45% of solar power, 30% of wind generation led by offshore farms, 5% of hydropower, and another 5% of biomass and e-fuel with nuclear power providing the remaining 15%, by 2060.

"All Japan needs is to continue installing as much solar as it did in the years before 2020. From 2014, you installed between 10 and 12 gigawatts on the peak," Rystad said.

Japan installed about 4 GW of new solar capacity last year, with its total outstanding solar capacity reaching 87 GW, the world's third-biggest behind China and the United States.

Rystad said mixing agriculture with solar panels - which also provide the shade preferred by some types of crops - as well as solar rooftops above roads, among other solutions, could help to expand the use of such power.

"The combination of offshore and onshore wind and solar, geothermal and biomass with solid backup from both battery and pumped hydro, should actually enable Japan to see self-dependency in energy in 40 years, or by 2060 even," he said.
