The World's Largest-Class Hydrogen Production, Fukushima Hydrogen Energy Research Field (FH2R) Now Is Completed at Namie Town in Fukushima

PVTIME - The New Energy and Industrial
Technology Development Organization (NEDO), Toshiba Energy Systems &
Solutions Corporation (Toshiba ESS), Tohoku Electric Power Co., Inc., and Iwatani
Corporation today announced that Fukushima Hydrogen Energy Research Field
(FH2R), which had been under construction in Namie town, Fukushima Prefecture
since 2018, has been constructed with a renewable energy-powered 10MW-class
hydrogen production unit, the largest-class in the world, at the end of
February.

FH2R can produce as much as 1,200 Nm3
of hydrogen per hour (rated power operation) using renewable energy. Renewable
energy output is subject to large fluctuations, so FH2R will adjust to supply and
demand in the power grid in order to maximize utilization of this energy while
establishing low-cost, Green hydrogen production technology.

Hydrogen produced at FH2R will also be used to
power stationary hydrogen fuel cell systems and to provide for the mobility
devices, fuel cell cars and buses, and more.

Today an opening ceremony was held on-site at
FH2R to celebrate its completion.

1.Project
Outline

Hydrogen, a concentrated energy source that can be stored for long periods
of time and transported over long distances, has emerged as the fuel of choice
for a wide variety of applications including cogeneration in fuel cell
batteries, and for fuel cell vehicles. Hydrogen supply systems in the future
are expected to generate hydrogen from renewable energy sources, and the entire
cycle from generation to use is expected to be completely CO2-free.

Japan’s Ministry of Economy, Trade and Industry promotes the adoption of
hydrogen in its Basic Hydrogen Strategy published in December 2017, which also
targets power-to-gas (P2G) technology for the storage and use of hydrogen-based
energy that can be stored in large quantities for long periods of time as
output increases. Power-to-gas using hydrogen requires a power grid
supply-and-demand balancing function (demand response) to maximize use of
renewable energy which undergoes significant fluctuations in output. The
technology also needs functions to optimize system operation according to
hydrogen supply and demand forecasting.

With sights set on expanding the use of renewable energy, Toshiba ESS,
Tohoku Electric Power Co., Inc., and Iwatani Corporation are working with NEDO
on a technology development project that aims to establish a hydrogen usage
business model and hydrogen sales business model for demand response. The
construction of the Fukushima Hydrogen Energy Research Field (FH2R) was
completed at the end of February. This hydrogen production facility had been
under construction in Namie town, Fukushima Prefecture (Tanashio Area, Tanashio
Industrial Complex in Namie-cho) since July 2018 and is equipped with a solar
energy-powered 10MW-class hydrogen production unit, the largest-class in the
world.

Renewable energy is subject to large output fluctuations, so FH2R aims to
maximize its utilization and establish low-cost, Green hydrogen production
technology without the use of storage batteries by adjusting to supply and
demand in the power grid.

Hydrogen produced at the facility will also be used to power stationary
fuel cell batteries and to support the mobility of fuel cell battery-powered
cars and buses, and more.

2. Overview of Fukushima Hydrogen Energy Research Field
(FH2R)

FH2R uses 20MW of solar power generation facilities on a 180,000m2
site along with power from the grid to conduct electrolysis of water in a renewable
energy-powered 10MW-class hydrogen production unit, the largest in the world.
It has the capacity to produce, store, and supply up to 1,200 Nm3 of
hydrogen per hour (rated power operation).

Hydrogen is produced and stored based on the hydrogen demand and supply
forecasting system’s forecasts for hydrogen demand in the market. Adjustments
to balance supply and demand in the power grid can be made by adjusting the
hydrogen volume produced by the hydrogen production unit to meet the power grid
adjustment needs of the power grid control system. The most important challenge
in the current stage of testing is to use the hydrogen energy management system
to achieve the optimal combination of production and storage of hydrogen and
power grid supply-demand balancing adjustments, without the use of storage
batteries.

To address this challenge, testing will begin to identify the optimal
operation control technology that combines power grid demand response with
hydrogen supply and demand response, using units of equipment that each have
their own different operating cycles.

Hydrogen produced at FH2R will mainly be transported in Hydrogen tube
trailers and hydrogen bundles, to be supplied to users in Fukushima Prefecture,
the Tokyo Metropolitan Area, and other regions.
