Panaji: Union minister R K Singh on Friday said that in order to achieve the net-zero carbon emission target, storing the renewable energy is necessary so that it becomes available round-the-clock. Chairing the inaugural function of G20 14th Clean Energy Ministerial meeting and 8th Mission Innovation meeting in Goa, Singh also said that the governments will have to work on building storage capacities of renewable energy.
The Union Minister for Power and New and Renewable Energy said,
If you want to get to net zero (carbon emission), then you will have to store the renewable energy so that it is available round-the-clock and that is a problem. The cost of storage is huge.
The G20 ministerial meeting will discuss the problems that lie on the path of climate action, energy transition and the strategies to achieve it.
We kept talking about how important energy transition is and how important climate change is. But if we were actually serious, we would have more capacity of batteries. We have only one country doing it, he said, without naming the country.

The union minister said that another challenge is that the reserves of lithium are limited and the bulk of the reserves are tied up by just one or two countries.
That is a major problem which we need to solve. We also need to address the question of chemistry – why only lithium and why not sodium-ion (in manufacturing batteries). I would request – let’s get together and crack this challenge of storage, the minister said.
Talking about India’s initiatives in this area, Singh said that the country plans to use green hydrogen and green ammonia as storage.
We are huge on pumped storage. We have 33,000 MW of pumped storage under different approvals. We have established 1,500 MW of pumped storage, he said.
The minister said that the G20 countries also need to address supply chain issues which were exaggerated by the COVID-19 pandemic and the Ukraine war.
India’s energy demand grew by 9.5 per cent last year as the economy grew by 7.5 per cent, he said.
The challenge is to add more capacity to the energy generation…We have added 1,82,000 circuit kilometres of transmission lines so that we can generate solar installations in Rajasthan and consume it anywhere. We have one grid-one market, he pointed out.
The minister also cautioned about the use of low-carbon hydrogen.
The problem with this one kilogram of hydrogen from natural gas will get you about 10 kilograms of carbon dioxide. How do we guarantee that it won’t leak out – that is a problem, he said.

NDTV – Dettol have been working towards a clean and healthy India since 2014 via the Banega Swachh India initiative, which is helmed by Campaign Ambassador Amitabh Bachchan. The campaign aims to highlight the inter-dependency of humans and the environment, and of humans on one another with the focus on One Health, One Planet, One Future – Leaving No One Behind. It stresses on the need to take care of, and consider, everyone’s health in India – especially vulnerable communities – theLGBTQ population,indigenous people, India’s different tribes, ethnic and linguistic minorities, people with disabilities, migrants, geographically remote populations, gender and sexual minorities. In wake of the currentCOVID-19 pandemic, the need for WASH (Water,SanitationandHygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign will continue to raise awareness on the same along with focussing on the importance of nutrition and healthcare for women and children, fightmalnutrition, mental wellbeing, self care, science and health,adolescent health & gender awareness. Along with the health of people, the campaign has realised the need to also take care of the health of the eco-system. Our environment is fragile due to human activity, which is not only over-exploiting available resources, but also generating immense pollution as a result of using and extracting those resources. The imbalance has also led to immense biodiversity loss that has caused one of the biggest threats to human survival – climate change. It has now been described as a “code red for humanity.” The campaign will continue to cover issues likeair pollution,waste management,plastic ban,manual scavengingand sanitation workers andmenstrual hygiene. Banega Swasth India will also be taking forward the dream of Swasth Bharat, the campaign feels that only a Swachh or clean India wheretoiletsare used andopen defecation free (ODF)status achieved as part of the Swachh Bharat Abhiyan launched byPrime Minister Narendra Modiin 2014, can eradicate diseases like diahorrea and the country can become a Swasth or healthy India.
