The government will also subsidize up to half the cost of battery storage systems, drawing from a 13 billion yen ($114 million) pot of funding in the fiscal 2021 supplementary budget, to make them competitive with other types of energy storage. It plans to solicit applications this fiscal year. [pdf]
The government is also reforming its battery energy storage system (BESS) regulations, with batteries set to play an important role in maximizing renewable energy supply and avoiding grid constraints. We look at the changes being implemented and what they mean for renewable energy projects in Japan.
TOKYO, April 28 (Reuters) - Japan will provide as much as $1.8 billion in subsidies for a slate of storage battery and chip-related projects, Industry Minister Yasutoshi Nishimura said on Friday, marking Tokyo's latest push towards greater supply chain security.
Japan’s 6th Strategic Energy Plan (released in 2021) and the GX (Green Transformation) Decarbonization Power Supply Bill (released in 2023) target increasing the share of non-fossil fuel generation sources to 59% of the generation mix by 2030 compared with 31% in 2022.
The government’s subsidy push has so far prompted an increasing number of private companies to invest in battery storage projects, including large-scale plants. With countries around the world pushing to accelerate their renewable deployments, it is more important than ever to maximize solar electricity generation.
Japan’s FIT scheme has contributed to the rapid deployment of solar and onshore wind generation capacity. But as the scheme provides a fixed price for the electricity produced, there is no incentive for generators to increase their output during peak demand hours or reduce output when the market is oversupplied.

Available data suggest that transport – land, sea and domestic aviation – probably accounts for more petroleum fuel use in the Marshall Islands than all other uses combined. Although there are opportunities to reduce transport energy use, these generally require some years to have a substantial impact.
Electricity use has been subsidized in the Marshall Islands since well before Independence in 1986 though a range of grants for capital investments, fuel purchases, hidden subsidies, and recently cross-subsidies from MEC bunkering profits, understandably resulting in high, and now unsustainable, levels of electricity use.

Energy storage is a potential substitute for, or complement to, almost every aspect of a power system, including generation, transmission, and demand flexibility. Storage should be co-optimized with clean generation, transmission systems, and strategies to reward consumers for making their electricity use more flexible. .

Each outlook identifies technology-, industry- and policy-related challenges and assesses the potential breakthroughs needed to accelerate the uptake. Thermal energy storage (TES) can help to integrate high shares of renewable energy in power generation, industry and buildings.
Thermal energy storage (TES) can help to integrate high shares of renewable energy in power generation, industry and buildings. This outlook identifies priorities for research and development. Transforming the global energy system in line with global climate and sustainability goals calls for rapid uptake of renewables for all kinds of energy use.
This review highlights the latest advancements in thermal energy storage systems for renewable energy, examining key technological breakthroughs in phase change materials (PCMs), sensible thermal storage, and hybrid storage systems. Practical applications in managing solar and wind energy in residential and industrial settings are analyzed.
