So, in order to find out why this was happening, police and professional organizations are working together to find out why.

The contents of the field survey are summarized by G1 Kim, Do-Hwan.

The place where the accident occurred is a facility that produces electricity by separating hydrogen from water using sunlight.

It was under test for 1,000 hours for full use after completion last month.

But in a month and a half, three hydrogen storage tanks on the outer walls of the building exploded.

Kangwon Techno Park said that the facilities were designed according to the gas safety law from the design stage to one part.

He also said that it is unlikely that a light, fast-spreading hydrogen would explode in an open space like an accident spot.

[Cho, Hyung-hwan / Team leader, Kangwon Techno Park: In an open space, hydrogen rises very quickly because hydrogen is spreading very quickly. The explosion is difficult to understand because the accident scene is an open space.]

It is not yet known whether the device was in operation at the time of the explosion.

The facility will be shut down at sunset when the sun goes down because it is a facility that uses sunlight. The blast time is about 6:22 pm and it is difficult to confirm.

Police, who joined the joint investigation since today (24th), are struggling to identify the cause.

There are no unfamiliar areas in the industry and there are no similar cases. In addition, nine specialized companies participate in R & D and facilities.
