Technologies

Our technologies address some of the world’s most pressing challenges, including reducing reliance on Rare Earth Elements, supporting the roll-out of the clean hydrogen economy and facilitating the development of the fuel cell and distributed energy markets.

As part of our growth strategy Time To ACT plc supports the global transition to Net Zero through the development and commercialisation of world-beating clean technologies.

Rare Earth-Free Permanent Magnet Generator (PMG)

The GreenSpur generator is a game-changing, cost-efficient solution, which addresses the critical materials risk facing the renewable energy sector.

The GreenSpur team have developed a highly innovative, axial flux, Rare Earth-free, permanent magnet generator (PMG). It incorporates multiple innovations, which make the use of ferrite magnets possible. It also uses patented aluminium coils to replace the copper windings used within existing generators and composite materials to aid lightweighting.

GreenSpur’s generator design is based around an axial-flux architecture, as opposed to the radial-flux architecture used in most motors and generators and the direct drive generators used in offshore wind turbines. In conventional, radial-flux generators, the rotor (rotating part of the generator) and stator (stationary part) are concentric cylinders, with magnetic flux flowing between them. The flux lines flow to and away from the axis of rotation of the generator. In an axial-flux generator, the rotor and stator are arranged as discs along the axis of the machine, and the magnetic flux flows parallel to this axis as “axial lines”.

The GreenSpur Rare Earth-free, permanent magnet generator (PMG) is applicable for:

  • Horizontal Axis Wind Turbines (offshore)
  • Vertical Axis Wind Turbines (onshore)
  • Vertical Axis Wind Turbines (offshore)
  • Tidal Turbines
  • Wave Turbines
  • Marine Turbines

Sectors

The sectors in which Time To ACT support are areas of long term sustainable clean-energy growth as society moves towards a goal Net Zero.

We tackle key bottlenecks within these sectors and provide enabling technologies or expertise which is required for successful deployment of each area. Our goal is to facilitate this growth and provide a platform for providing investor value through a long term approach to investing in clean technology and renewable energy.

Wind Energy

Wind energy is the use of wind turbines to generate electricity. Wind power is a sustainable, renewable energy source that has a much smaller impact on the environment than burning fossil fuels. Wind farms consist of many individual wind turbines, which are connected to the electric power transmission network.

In 2020 wind supplied almost 1600 TWh of electricity which was over 5% of worldwide electrical generation and about 2% of energy consumption. [1] The challenge with wind, both onshore and offshore, are sourcing the Rare Earth Elements needed for the turbines. Time To ACT technology helps support the long term potential for wind energy, tackling this major global shortage in Rare Earth Elements.

Green Hydrogen

Green hydrogen is hydrogen that is generated entirely by renewable energy. Green hydrogen has significantly lower carbon emissions than grey hydrogen, which is produced by steam reforming of natural gas using fossil fuels and represents 95% of the market. Certified green hydrogen requires an emission reduction of >60-70% below the benchmark emissions intensity threshold.

"Hydrogen offers the greatest potential to decarbonize difficult-to-abate sectors like steel, cement and heavy duty transport." [2]

Hydrogen can be used as a hydrogen fuel for fuel cells or internal combustion engines. In 2020, major European companies announced plans to switch their truck fleets to hydrogen power. [3] Additionally, hydrogen-powered aircraft are already being designed by Airbus, with a planned release of the first commercial aircraft by 2035. [4]

Fuel Cells

A fuel cell is an electrochemical cell that converts the chemical energy of a fuel into electricity. [5] Fuel cells are used for primary and backup power for commercial, industrial and residential buildings and in remote or inaccessible areas. They are also used to power fuel cell vehicles, including forklifts, automobiles, buses, boats, motorcycles and submarines.

Clean Technology

Clean technology, in short cleantech, is any process, product, or service that reduces negative environmental impacts through significant energy efficiency improvements, the sustainable use of resources, or environmental protection activities.

Investments in clean technology have grown considerably since coming into the spotlight around 2000. According to the United Nations Environment Program, wind, solar, and biofuel companies received a record $148 billion in new funding in 2007 as rising oil prices and climate change policies encouraged investment in renewable energy. From COP26, investment into clean technologies could reach £95 trillion. [6] 

Time To ACT technology helps support many of the key technologies of the cleantech industry.

Surface Coatings

Specialist surface coatings are used in harsh and high temperature operating conditions across a range of industries. These can be used in gas turbine and process industries such as hydrogen generation.

Time To ACT technologies from Diffusion Alloys have been used in power, aerospace and process industries for many years. Diffusion Alloys’ strategy is to concentrate on large scale hydrogen generation, solid oxide fuel cell (SOFC), solid oxide electrolysis (SOE), clean energy storage, medium scale hydrogen generation, concentrating solar power (CSP), nuclear and other specialist life extension opportunities.
