Our journey began in 1985, providing Apple computer maintenance and repair for the cotton industry in Pakistan. This early experience instilled a deep understanding of technology's role in optimizing operations. Over the decades, we've expanded our expertise to encompass comprehensive corporate ICT, RE and radio communication solutions. We've delivered end-to-end telecommunication infrastructure, EPC (Engineering, Procurement, and Construction) services, and regulatory support for a wide range of products used in Pakistan's Oil & Gas fields, serving industry leaders like Union Texas/BP, Lasmo/Eni, OMV, BHP and Maersk. This extensive experience positions us as a one-window contractor for efficient enterprise network rollout. Moreover, we bring a unique blend of international vision and regional expertise to project management, uniting diverse skill sets and knowledge areas. This includes ensuring 24x365 uninterrupted power – a critical aspect in a field development where technology is constantly evolving and strong leadership is essential.

As the world embraces sustainable development, we recognize the urgency of eliminating pollution. That's why we're partnering with GRZ-Technologies of Switzerland to champion Green Hydrogen, a groundbreaking solution for clean energy. This patented low-pressure H2 storage technology facilitates fuel cell power generation, offering the most potent independent energy solution developed in recent decades. Compact, safe, and containerized, it provides a scalable power range of 0.3-10 Megawatts for rapid deployment, empowering long-term energy independence.

MAS Energy s.r.l. is an italian family-owned company, based in Palo del Colle (BA) estabilished by Ing. Gaetano Mastrandrea with over two decades in the successful development of photovoltaic and wind projects in Southern Italy.

With a passion for renewable energy and a deep understanding of the Italian energy market, Gaetano, with the collaboration of his son Onofrio Mastrandrea and his team, aims to promoting sustainable energy solutions and contributing to the fight against climate change.

MAS Energy has since grown to become a leader in the Southern Italian renewable energy sector, providing innovative and efficient solutions for businesses and communities alike. It has developed over 150 MW of authorizations, with around 50 MW currently in operation. Furthermore, at present there are over 500 MW of Battery Energy Storage System (BESS) plants awaiting approval.

The company's success is rooted not only in dedication to professionalism and environmental consciousness, but also in strong collaboration with local authorities and communities. We prioritize involving them in all of projects to ensure that the area is properly protected.

According to Gaetano Mastrandrea, “renewable energy has the potential to revolutionize the way we power our World. By harnessing the power of the sun and wind, we can create clean and sustainable energy sources that will help to reduce our reliance on fossil fuels. However, in order to fully realize the benefits of renewable energy, we need to address the issue of energy storage and transportation”.

This is where green hydrogen comes in. Undoubtedly it is a highly versatile element with a wide range of possible applications. It can be used as fuel cells, for heating and cooking, as well as for transportation.

Balancing the energy market, using hydrogen to accumulate energy during production hours and release it during the hours of greatest demand and absorption, is certainly the most interesting and convenient application.

Italy, as one of the largest producers of green energy, has at the forefront of promoting the use of hydrogen as a sustainable energy source. The country has set ambitious targets for reducing its carbon emissions and achieving a carbon-neutral economy and is investing heavily in the development and deployment of hydrogen technologies.

Overall, Hydrogen, combined with renewable energy, has the potential to revolutionize the energy sector and it holds great promise for a cleaner and more sustainable future.

Thanks to a global perception, MAS Energy recognizes that both of these worlds, essentials to our future, have their strengths and weaknesses. That's why it is proposed as a conduit between the two worls, so closely linked, leveraging its expertise create innovative solutions that meet the needs of businesses and individuals alike.

It will require investment and innovation, but the potential benefits are enormous. By working together towards a common goal, with continued progress and collaboration, we can create a world powered by renewable energy and fueled by hydrogen.

SHG Supreme Hydrogen AB, founded in 2018, is a knowledge and engineering company developing and applying circular, green, and emission-free energy solutions. Hydrogen is a clean and sustainable secondary energy source for the future of our planet. Hydrogen can be used for transport, real estate, power supply, grid balancing, modern agriculture, and industrial purposes.

Industrial scale hydrogen supply is today mainly based on natural gas or biomass. But, the technology behind hydrogen production from water is known since the 1830-ies. Our vision is that electrolysis of water will contribute to a totally emission-free mode of storing and using energy – a system where energy can be handled and distributed in the same way as we have done with fossil fuels.

SHG Supreme Hydrogen AB  is focused on development and implementation of systems for production, handling and usage of green hydrogen, and other products generated by green power.

Established in 2005 the company has an extensive list of references within transport, storage, and bunkering of LNG/LBG. The company has delivered several turn-key filling stations and bunkering facilities for ships, including the bunkering facility for Fjord Line in Hirtshals, the first facility of its kind in Denmark. Since 2018, Liquiline’s focus has been within hydrogen. In 2019 a partnership with Green Hydrogen Systems was agreed, regarding sale of their electrolysers in Norway. Liquiline is today a wholly owned subsidiary of Hydrogen Solutions (HYDS). HYDS develops, builds, owns, and operates hydrogen plant, and their strategy is to produce green hydrogen and hydrogen derivatives scalable and locally. HYDS opened its first plant (1 MW) at Norway’s West Coast in May this year, and the second one is under construction in Egersund with a planned start-up in December 2023.
