Using the most abundant element for energy


Hello Hydrogen, You're our No.1 element!

Hydrogen is increasingly emerging as an important part of the clean energy mix needed to ensure a sustainable future.

Costs are falling for hydrogen being produced via renewable energy. These falling costs, together with new technologies, combined with the urgency of cutting greenhouse-gas emissions, has given clean hydrogen as an energy source, unprecedented political and business momentum.

Matching demand

The International Renewable Energy Agency (IRENA) values greatly the potential of hydrogen fuel for hard-to-decarbonise energy uses, including energy-intensive industries, trucks, aviation, shipping and heating applications.

However, the decarbonisation aspect depends on how hydrogen itself is  produced. Hydrogen itself does not float around as a gas, it is usually bound with other elements, such as water. Electrolysation, powered by another green technology is the most favourable option.

Different colours of hydrogen

Hydrogen extraction options can be divided into:

  • grey (fossil fuel-based),
  • blue (fossil fuel-based production with carbon capture, utilisation and storage) and,
  • green (renewables-based) hydrogen.

Green hydrogen produced through renewable-powered electrolysis is projected to grow rapidly in the coming years. There is also a clear seasonal matching between wave energy and electricity demand in many parts of the world, such as the U.S. and the United Kingdom. IRENA states that In some parts of the world, such as the densely populated west coast of India, there is even a daily matching of wave energy to electricity demand.

IRENA’s other findings

  • Important synergies exist between hydrogen and renewable energy. Hydrogen can boost renewable electricity market growth and broaden the reach of renewable solutions.
  • Electrolysers can add demand-side flexibility. In advanced European energy markets, electrolysers are growing from megawatt to gigawatt scale.
  • Blue hydrogen is not inherently carbon free. This type of production requires carbon-dioxide (CO2) monitoring, verification and certification.
  • Synergies may exist between green and blue hydrogen deployment, given the chance for economies of scale in hydrogen use or logistics.
  • A hydrogen-based energy transition will not happen overnight. Hydrogen use is likely to catch on for specific target applications. The need for new supply infrastructure could limit hydrogen use to countries adopting this strategy.
  • Dedicated hydrogen pipelines have existed for decades and could be refurbished along with existing gas pipelines. The implications of replacing gas abruptly or changing mixtures gradually should be further explored.
  • Trade of energy-intensive commodities produced with hydrogen, including “e-fuels” could spur faster uptake or renewables and bring wider economic benefits.

Technical Terms and Vocabulary

Process by which the solar panels are exposed to the sun’s radiation. Effectively how much power can be harnessed by a particular system.

A method of converting solar energy into direct current electricity.

kWp (Unit)
Kilowatt peak, the output achieved by a solar module at full solar radiation.

kWh (Unit)
Kilowatt hour, unit of energy equivalent to one kilowatt (1 kW) of power expended for one hour.

MWp (Unit)
Megawatt peak, the output achieved by a solar module at full solar radiation. 1 MW is 1000 kW

MWh (Unit)
Megawatt hour, unit of energy equivalent to one Megawatt (1 MW) of power expended for one hour.

Converts direct current (DC) electricity into alternating current (AC) electricity, which can be used by electrical appliances.

Index linked
RPI (retail, price index) running at a percentage inflation per annum

Embedded generation
Equipment embedded within a site, generating power through low carbon natural gas or via green generation technologies such as Solar PV or Onshore wind

Private wire generation
Equipment is located at a development nearby and power is provided direct from the facility via a “private wire”

Off Grid
providing a dedicated power plant and not being connected to the local or National energy networks.


Hausch and Hydrogen

We are delighted to be working side by side with  Renewable Hydrogen Technologies Ltd as one of our partners. They are hydrogen energy specialists with a ‘supply side’ approach to Variable Renewable Energy.

Their Philosophy is “to design and create integrated and resilient energy systems which bypass net zero solutions and technologies and deliver zero emission technologies and infrastructures”.

Research and Development::

  • hybrid energy storage technologies
  • integration of hydrogen conversion and reconversion technologies into location specific contexts
  • design and development of storage system integration software and engineering design of whole energy systems.

    Next Steps...

    The next step is really just to get in touch with us with any questions about or your ideas for embracing renewable energy and all its financial and environmental benefits.

    We are happy to walk you through the whole process from what “information is needed?” to “how long will it take?” to “Great! when can I start?” 🙂

    We look forward to hearing from you.
