How Japan's Big Plans For A 'Hydrogen Society' Fell Flat

Tokyo, Japan:

It was as soon as touted as a miracle resolution to Japan’s vitality issues: making a “hydrogen society” by sharply ramping up use of the gas for autos, trade and housing.

However the nation’s plan to increase its hydrogen market and slash greenhouse emissions has suffered delays and criticism over the gas’s inexperienced credentials.

As G7 local weather ministers meet this weekend within the northern Japanese metropolis of Sapporo, listed here are some key factors concerning the technique:

Bold Plans

In 2017, Japan turned the primary nation to plot a nationwide technique for hydrogen energy, aiming to drastically scale up its use by 2030.

The colourless, odourless gasoline is an thrilling prospect on paper.

It may be produced, saved and transported in giant portions, and doesn’t emit carbon dioxide when burned.

These qualities are engaging to Japan, which is closely reliant on fossil gas imports.

Most of its nuclear reactors are nonetheless offline after the 2011 Fukushima catastrophe, and the nation set a aim two and a half years in the past of reaching carbon neutrality by 2050.

Gas Cell Blues

Hydrogen-powered gas cell autos, which Japanese automakers helped pioneer, have been a key a part of the unique plan.

The federal government had hoped for 40,000 of those vehicles to be on the street by 2020, and 800,000 by 2030.

However by the top of final 12 months, simply 7,700 items had been offered within the nation since 2014.

Regardless of subsidies for consumers, they continue to be “very costly”, even in comparison with battery-powered electrical vehicles, Kentaro Tamura, a Japan-based professional on the Institute for World Environmental Methods (IGES), instructed AFP.

Hydrogen refuelling stations have excessive set up and maintenance prices, and are uncommon compared to charging spots for electrical autos, Tamura added.

Hydrogen-Powered Houses

The outcomes have been higher however nonetheless modest in housing — the opposite main space initially earmarked for hydrogen growth.

A residential gas cell programme referred to as “Enefarm” was meant to equip 5.3 million Japanese houses by 2030.

It makes use of gasoline to create hydrogen that reacts with oxygen from the air to generate electrical energy and warmth water.

However by the top of 2022, simply 465,000 methods had been put in, far in need of the federal government’s goal of 1.4 million by 2020.

Worth is a key issue right here too, Tamura mentioned, with set up prices “very excessive in contrast with various applied sciences like warmth pumps”.

‘Gray’ Space

Vitality consultants have been sceptical of Japan’s hydrogen technique from the beginning, as a result of it was launched with out making a dependable provide chain for environmentally pleasant “inexperienced” hydrogen, produced from renewable vitality sources.

As an alternative, Japan opted for so-called “gray” hydrogen, made utilizing greenhouse gas-emitting coal, petrol or gasoline, and “blue” hydrogen, which additionally comes from fossil fuels however with the carbon emissions captured and saved.

Within the meantime, international locations akin to China and a few European nations have moved sooner on inexperienced hydrogen, which stays uncommon and costly however is essential to decarbonisation, the Japanese Renewable Vitality Institute think-tank says.

In March, Tokyo agreed to spend $1.6 billion on an formidable however controversial enterprise in Australia to provide liquid hydrogen from lignite coal and export it to Japan.

However critics say the undertaking’s “blue” hydrogen claims are primarily based on carbon seize expertise that doesn’t but exist.

Co-Firing Controversy

Regardless of the setbacks, Japan will revise its hydrogen technique by the top of Might, with the Nikkei enterprise day by day reporting plans to extend its provide of the gas to 6 occasions the present stage by 2040.

Additionally it is selling one other use for hydrogen and its spinoff ammonia: burning it alongside gasoline and coal at current energy stations, to cut back carbon emissions.

An official from the Ministry of Financial system, Commerce and Trade instructed AFP that ammonia co-firing is “a practical technique of vitality transition that’s extra CO2-reducing and economically environment friendly than the early phase-out of coal-fired energy and its alternative with renewable vitality”.

However local weather campaigners query the worth of the costly follow on the trail to cleaner vitality.

Japan is “the one G7 member” pushing for co-firing, Greenpeace’s Hirotaka Koike mentioned, describing it as a “nationwide coverage to maintain the ‘sundown’ trade (of thermal energy stations) alive”.
