Energy Tech Summit 2024: Mercury Launch and Innovations in Berlin

Berlin was abuzz with groundbreaking energy innovations last week as the WIRED x Octopus Energy Tech Summit took center stage. The event, which drew industry leaders and enthusiasts alike, saw the unveiling of several exciting developments, including the launch of ‘Mercury’, described as the ‘Bluetooth of energy’. The summit also featured the construction of a wind turbine in just eight hours and a convoy of electric vehicle (EV) enthusiasts making their way from London to Berlin.

The highlight of the summit was the announcement of Mercury, a new initiative aimed at setting a global standard for energy technology integration. According to Greg Jackson, CEO of Octopus Energy, Mercury is designed to allow millions of smart energy technologies to seamlessly work together, much like Bluetooth does for tech devices. This initiative is spearheaded by Kraken, the technology arm of Octopus Energy, which is forming a global consortium to establish these new technical standards.

Mercury: A Global Standard for Energy Integration

Mercury aims to address two critical needs as more people transition to electric technologies: ensuring these products fit seamlessly into daily life and supporting the energy grid. With the rise of heat pumps, EVs, and batteries, there is a pressing need to manage their power usage efficiently to avoid overloading the grid. By optimizing these devices to operate when clean energy is abundant, Mercury seeks to create a coordinated, flexible energy ecosystem.

Kraken is actively seeking partners to join this initiative, calling on manufacturers, utilities, regulators, and technology providers to unite in setting these new standards. The goal is to make clean energy systems as reliable and user-friendly as Bluetooth, eliminating the hassle of incompatible gadgets and complex setups.

“We want your home’s clean energy systems to be as reliable as Bluetooth is now—no hassle, no confusing setups or gadgets that won’t talk to each other, just seamless integration.” – Greg Jackson, CEO of Octopus Energy

Innovations Unveiled: Cosy 10 and Fat Boy Spin

In addition to Mercury, Octopus Energy introduced the Cosy 10, a new 10-kilowatt heat pump designed to efficiently heat mid-sized homes. This follows the success of last year’s Cosy 6, which was tailored for smaller residences. The Cosy 10 promises to deliver the same efficiency and convenience, making it a significant upgrade for homeowners seeking sustainable heating solutions.

Another highlight was the rapid construction of ‘Fat Boy Spin’, a travelling wind turbine built onsite in Berlin in just eight hours. This feat demonstrated the potential for quick deployment of renewable energy technologies without compromising quality or safety.

The Journey to Berlin: A Showcase of Sustainable Travel

The summit was not just about showcasing new technologies; it was also an opportunity to demonstrate the viability of sustainable travel. A convoy of EVs, including participants like Jerome Foster, the youngest advisor to the White House, and Top Gear racing driver Becky Evans, embarked on an overnight journey from London to Berlin. This 600-mile trip, dubbed the ‘Octobahn’, highlighted the fun, seamless, and eco-friendly future of travel.

Participants shared their experiences, emphasizing the ease and enjoyment of long-distance EV travel, further reinforcing the message that the future of transportation is already here.

Looking Ahead: A Call for Industry Collaboration

The Energy Tech Summit 2024 underscored the readiness of technology to power a green future. With initiatives like Mercury and products like the Cosy 10, Octopus Energy is leading the charge in making energy not only greener but also more accessible and cost-effective for everyone. The company is calling on the entire industry to join this mission, emphasizing the importance of collaboration in achieving a sustainable energy ecosystem.

As the summit concluded, the message was clear: the tools and technologies needed for a sustainable future are already available. Now, it’s about bringing them together and setting new standards to ensure a seamless transition to a greener world.
