Understand 10 key barriers hindering the scaling of renewable energy. KPMG and renewable energy specialists share their innovative recommendations.

To achieve sustainability, we need more out of the box thinking like this one. We need an education system that is less conformist and triggers imagination and innovation. Decades of a conformist approach to the way the acquisition of education and new knowledge is sponsored, delivered, assessed and rewarded has stifled new approaches to existing problems, and may have killed some Einsteins.

It is exciting to know the battery storage technology for RE generated power storage using low quality sand. Pls read and share as this alternative RE storage option is highly essential to adopt to India’s 2030 goals of 500GWs of RE power .

When you think of how cooking in hot sand is a technique that has been used for hundreds of years in villages in China and India, this concept makes perfect sense and seems so obvious. This is #BESS on another level and I think that this is going to be a #gamechanger. The fact that it can use low-grade sand or sand-like particles will help ensure #foodsecurity and the best part is that we don't have to mine #lithium. Your thoughts?

I am not an expert of energy storage, a sand battery is totally New for me! I am curious to hear more from my network! Were you aware of this option for storage? How would you rate it in terms of performances like safety, availability, reliability, cost, power intensity? Or we should look to other parameters?

Tommi Eronen and the operational teams at Polar Knight Energy are doing great work in their innovation that provides stable and affordable heat storages for district heating and industrial applications. Fascinating to learn and understand how sand and sand-like materials are storage mediums for heat. #sustainableenergysolutions #researchanddevelopment #globaleconomy #assetmanagementinsights World Economic Forum

I've been to Finland for a school semester and I can tell you they have no sand in there :) If Finland can harvest renewable energy from sand they don't have, what do you think can be done with a place such as the Empty Quarter? Think about it #finland #saudiarabia #sustainability #environment

This concept indeed marks a progressive step in harnessing renewable energy more efficiently. The last similar initiative was with volcanic rocks, which was fascinating but somewhat limited due to resource availability. Considering sand's increasing scarcity, it prompts us to explore alternatives. One potential candidate could be salt, given its melting point and heat retention properties, which could withstand the system's 500-degree requirement. It's intriguing to consider how materials typically deemed 'common' could be pivotal in energy innovation. Diversifying our options could not only enhance accessibility due to regional availability, but also potentially improve the efficiency and sustainability of storing solar energy for off-peak times. Further research and experimentation in this direction could be incredibly promising for our renewable energy trajectory. #RenewableEnergy #InnovationInStorage #SustainableSolutions #EnergyEfficiency

How much feasible and scalable this technology could be?
