With a passion for providing the market with plug and play, tailor made renewable energy solutions, retired Swedish engineer Hans-Olof Nilsson founded Nilsson Energy to be a one stop shop and provider of complete commercial off-grid energy solutions.

It all started with Nilsson investing his own capital into developing his 5,400 sq. ft family home near Gothenburg in Sweden into a state of the art off-grid villa back in 2014. Now used as the company’s demo site, the house, powered by the sun, has so far hosted 2,400 visitors. Solar energy is stored in batteries and hydrogen (H2) gas securing long term storage. By using fuel cell technology to convert hydrogen gas to electricity and heat, the household is completely self-sufficient, even when sunshine is scarce. The house generates 3,000Nm3 of hydrogen from its 23kWp of solar panels.

Nilsson, a retired engineer from the refrigeration industry, is a pioneer who turned his passion into a business. “Being a pioneer is all about sticking your neck out, taking calculated risks and acting accordingly. Making the impossible, possible,” he said. With the introduction of Nilsson Energy, his passion has developed into supplying commercial customers with renewable energy solutions. Hence the name of the product range Renewable Energy 8760 or RE8760 for short.

Product range

Nilsson Energy is a fast-growing game changing system integrator of complete on-site, off-grid, emission free renewable energy systems, including large scale storage of energy in hydrogen.

Established in 2017, the company is initially focussing on creating a solid market footprint in its home market Sweden. It is experiencing very strong customer interest from a variety of geographical markets, from the Middle East, to Asia and Africa.

“There is clearly a great demand for and an interest from customers of on-site energy solutions for a system solution provider like Nilsson Energy. We are very dedicated to the opportunity and feel that we are filling an important and highly relevant gap in the value-chain,” Martina Wettin, Nilsson Energy’s Marketing and PR Director, told gasworld.

“The company targets commercial customers and we are looking for co-operation with industry partners such as technology companies, energy companies as well as commercial energy consumers of scale,” Wettin, also a Partner in the company, explained. “The customers are likely to be situated in areas where availability and reliability of locally produced renewable energy is highly sought after for all the 8760 hours that make out a year. Nilsson Energy´s product range is branded RE8760 and will always be customised to suit the individual customer energy profile and prerequisites.”

A Nilsson Energy system produces both hydrogen and oxygen. Oxygen, produced locally by renewable energy, can be used by hospitals, the medical industry and other process industries.

A Nilsson Energy RE8760 system solution consists of well proven and commercialised technology and can be remotely monitored. The system can be packaged in containers and is modular and scalable for the situation where gradual upscaling is of interest.

“Nilsson Energy uses solar and/or wind power, add water and create off-grid, on-site and emission free plug-and-play energy solutions via electrolyse, battery storage and long-term storage in hydrogen. When additional energy is needed the stored hydrogen is converted to electricity and heat via fuel-cell technology. RE8760 can use any water supply available and can also bring water to site creating closed system solutions should this be required. A RE8760 system also produces oxygen when spitting water into hydrogen and oxygen creating yet a valuable resource for its customer,” Wettin said.


Last year, Nilsson Energy won a contract in November to build an independent off-grid hydrogen production plant connected to the an existing hydrogen fuelling station in Mariestad, Sweden. The contract also includes building a solar park, whose solar energy constitutes the fuel for the system. Working together with municipality of the Mariestad and energy company VänerEnergi, this will be the world’s first solar-powered hydrogen refuelling station.

Founding father of Nilsson said, “We have the ‘recipe’ for harvesting solar and wind energy, adding water and building completely self-sufficient energy system solutions for all types of energy consumers. Being the first in the world contracted to build an off-grid hydrogen fuelling station ‘fed’ by the sun is obviously fun and important.”

The solar cell park and the energy system solution at the hydrogen fuelling station is expected to be taken into operation in late autumn 2018.

Nilsson Energy is also working with the municipality of Vårgårda to add its RE8760 technology to a number of blocks of flats being refurbished to tackle energy inefficient housing estates.


“We want to scale globally and rapidly together with industrial partners,” Wettin replied when asked what plans Nilsson Energy has for the future. “Our core business objectives include being a highly respected and solid energy system integrator for off-grid stationary applications. We will also aim to scale globally, starting with mature hydrogen markets.”
