The 2021 BT Young Scientist & Technology Exhibition will be a virtual event and organisers say they will rise to the challenge to make it a spectacular success.
Speaking to RTÉ's Morning Ireland, Dr Tony Scott, co-founder of the exhibition, said Covid-19 restrictions will prevent the event going ahead in the RDS.
However, he said that for students entering the virtual competition it will not make much difference as they will apply online as always with this year's entry fee waived.
Dr Scott said it will continue to be a one-to-one judging process between the student and judge - with 15 minutes spent talking virtually to each student about their project.
He said that young people are adaptable and will rise to the challenge, along with the organisers.
The new format will allow an international audience to view the event online for the first time.
Dr Scott said entries are already coming in and with scientists playing a key role in combatting Covid-19 he thinks many will be inspired to take part,
Entries close on 22 September and over 2,000 applications are expected, with 550 projects making the final cut.
