Entrepreneur Justin Hall-Tipping questions the notion of 'normal' in terms of energy and how that can lead to some extraordinary breakthroughs. In his recent presentation at TEDGlobal 2011, Hall-Tipping describes how we can generate, use and store energy right from where we are. As both energy and water pose the most significant challenges to future global demands—especially in the developing world—Hall-Tipping believes he has found the answer in the simple electron.

Generating and Using Energy

When you think of carbon as a material, you generally think of it as black in color. At the nanoscale, however, things work and act very differently than the way we normally see them. At the nano-level, carbon is actually transparent and flexible.

In an experiment, Hall-Tipping discusses taking graphite, the most stable form of carbon, and blasting it with a vapor. When the vaporized carbon condenses, its form changes and it actually becomes a thousand more times conductive than copper. How is that possible? Again, elements act and appear differently at the nano-level.

By combining carbon with a polymer, which can then be affixed to a window (with great transparency and flexibility), its colored state can be changed and controlled. When it's in a colored state, it will reflect light and heat away, and when it's in its bleached state, it will let all the light and heat in, and any combination in between.

To change its state, all it takes are two volts at mili-second pulses. Once you change its state, it stays there until you change it again.

What if we didn't have to rely on artificial light to get around at night?

In combining two nano-materials, a detector and an imager, it's possible to take all the infrared light at night and convert it in the space of the two small films. Hall-Tipping says this enables you to “play an image that you can see through by taking infrared wavelengths and converting them into an electron.”

“Suddenly, you've converted energy into an electron on a plastic surface that you can stick on your window, and because it's flexible, it can go on any surface whatsoever,” he says.Therefore, “the power plant of tomorrow, is no power plant.”

Storing free energy

Unfortunately, Hall-Tipping says that the best thing we have going in terms of storing energy is the lead acid battery in terms of dollars per watt stored.

E-box, however, is testing new materials that allows you to essentially park an electron and hold it until it's needed, enabling the generation of clean, efficient and cheap energy onsite. “If you don't need it, you can convert it back up onto the window and beam it onto another place,” Hall-Tipping says. Therefore, “the grid of tomorrow, is no grid.”

Water

Hall-Tipping is optimistic that clean, efficient energy will one day be free. And if this can be accomplished, “you get the last puzzle piece, which is water.”

As water supplies diminish—as they already are in some parts of the world—we will have to turn to the ocean, which will require some $19 trillion of investment in desalination plants. These also require tremendous amounts of energy, or twice the world's supply of oil, to run the pumps to generate the water, according to Hall-Tipping.

“We're simply not going to do that,” he says. “But in a world where energy is freed and transmittable easily and cheaply, we can take any water wherever we are and turn it into whatever we need.”

Hall-Tipping believes these developments can remedy the cause of deaths of millions lacking clean water. And in order to change this, the answer is “to be able to get exquisite control over a building block of nature, the stuff of life, the simple electron.”

Major move forward for UK’s nascent marine energy sector

The UK’s nascent marine energy sector starts exporting electricity to the grid as the most powerful tidal turbine in the world begins to generate power

Although the industry is small and the technologies are limited, marine-based energy systems look to be taking off as “the world’s most powerful tidal turbine” begins grid-connected power generation at the European Marine Energy Centre

At around 74 metres long, the turbine single-handedly holds the potential to supply the annual electricity demand to approximately 2,000 homes within the UK and offset 2,200 tonnes of CO2 per year.

Orbital Marine Power, a privately held Scottish-based company, announced the turbine is set to operate for around 15 years in the waters surrounding Orkney, Scotland, where the 2-megawatt O2 turbine weighing around 680 metric tons will be linked to a local on-land electricity network via a subsea cable. 

How optimistic is the outlook for the UK’s turbine bid?

Described as a “major milestone for O2” by CEO of Orbital Marine Power Andrew Scott, the turbine will also supply additional power to generate ‘green hydrogen’ through the use of a land-based electrolyser in the hopes it will demonstrate the “decarbonisation of wider energy requirements.” 

“Our vision is that this project is the trigger to the harnessing of tidal stream resources around the world to play a role in tackling climate change whilst creating a new, low-carbon industrial sector,” says Scott in a statement. 

The Scottish Government has awarded £3.4 million through the Saltire Tidal Energy Challenge Fund to support the project’s construction, while public lenders also contributed to the financial requirements of the tidal turbine through the ethical investment platform Abundance Investment.

“The deployment of Orbital Marine Power’s O2, the world’s most powerful tidal turbine, is a proud moment for Scotland and a significant milestone in our journey to net zero,” says Michael Matheson, the Cabinet Secretary for Net-Zero, Energy and Transport for the Scottish Government. 

“With our abundant natural resources, expertise and ambition, Scotland is ideally placed to harness the enormous global market for marine energy whilst helping deliver a net-zero economy.

“That’s why the Scottish Government has consistently supported the marine energy sector for over 10 years.”

However, Orbital Marine CEO Scott believes there’s potential to commercialise the technology being used in the project with the prospect of working towards more efficient and advanced marine energy projects in the future. 

We believe pioneering our vision in the UK can deliver on a broad spectrum of political initiatives across net-zero, levelling up and building back better at the same time as demonstrating global leadership in the area of low carbon innovation that is essential to creating a more sustainable future for the generations to come.” 

The UK’s growing marine energy endeavours

This latest tidal turbine project isn’t a first for marine energy in the UK. The Port of London Authority permitted the River Thames to become a temporary home for trials into tidal energy technology and, more recently, a research project spanning the course of a year is set to focus on the potential tidal, wave, and floating wind technology holds for the future efficiency of renewable energy. The research is due to take place off of the Southwest coast of England on the Isles of Scilly
