The Green Energy Forum at Sustainability LIVE London 2023 explored the role of renewable energy sources in transforming the global energy landscape — an essential step in tackling climate change and achieving sustainable development goals. The discussion examined current trends and innovations in the green energy industry, the challenges facing the adoption and scaling of renewable energy, and the opportunities and implications for various sectors of the economy.
It concluded that the role of government in accelerating the transition to green energy was upping engagement, furthering education, improving consistency, boosting collaboration, reducing widespread control and cohesively managing capacity.
“What we're now seeing from the government is a recognition that this is a key solution in decarbonising the heating sector in the UK, as heating makes up about a third of the UK carbon emissions.
"But actually, in terms of the long term consistency, showing the market — the supply chain in particular — that it's worth their while and their investment.
“The sector needs clarity about the ongoing support, but also the regulatory environment and other restrictions. In the longer term that can actually really help for industry to pivot towards providing solutions in these sectors.”
Challenges in scaling green energy
“We deliver services that can never be off. So historically, the backup to the primary energy source has been through self-generation, typically through diesel, which obviously is not particularly green.
“And the technology now is there to replace that, but it doesn't work at scale and so in an ideal world we need a different configuration. It might just not be technology, it might be the way in which we use the services that we provide. So can we provide that robustness without the need for non-green technology?”
The future of energy
“One of the trials that we have going right now is looking at people's tolerance towards preheating their buildings when renewable energy is available in the early afternoon. So you're not just automatically turning on at 5:30 p.m.,” shared Stephen Lorimer, Clean Energy Cities, Centre for Net Zero – part of the Octopus Energy Group.
“Because if everyone's doing that, once we electrify heat, we basically have the World Cup final times 20. It is very expensive to build an electricity network for that and not palatable to any politician in the future.
“We have a product called Intelligent Octopus that you can say to look at the market and see that the lowest prices and the most available energy is at two in the morning. Let's have all kinds of cars and batteries charging when that happens at two in the morning.
“Now, of course, once everyone plays this game, it's self-defeating. But, you know, these things do help in trying to manage the local energy system in the future.”
Success stories in green energy
“In terms of the pricing aspect of wholesale markets, the biggest moment we've seen is going from shorter term hedging and risk management by utilities — which is mainly what they did when they were managing the risk of fossil fuel generated assets — up to two or three years. Now, with PPAs especially, the demand has grown to up to ten years where they want to manage the risk and use our products as well to hedge,” said Viviana Ciancibello, Senior Business Developer, European Energy Exchange (EEX).
“So we extended our futures from six to ten years to facilitate that. The most demand we've had from that has been in Spain, where the government stopped offering subsidies to new renewable energy assets back in 2017, I believe, notwithstanding all of the other interventions they've done in the past few years.”
