f-cell: Stationary applications in buildings

Stationary applications in buildings was one of the afternoon sessions H2 View tuned into virtually at f-cell Stuttgart today.

We’ve been bringing you coverage throughout the day and if you’ve missed anything so far, you can read our Opening Plenary recap here, and our Hydrogen and Fuel Cell Applications Plenary recap here.

Takuya Ito, Manager of the Residential Solution Technology Department at Tokyo Gas was the first speaker of the session and he highlighted a fuel processing system for a residential fuel cell cogeneration system, ENE-FARM.

A fuel processing system is a system for producing hydrogen from city gas to be used as fuel for fuel cells. It is made up of a desulfurizer, to remove the sulfur used as an odorant in city gas, and a fuel processor for producing and purifying hydrogen gas.

By slimming down and reducing the cost of fuel processing systems via technologies that develop low-cost and high-performance desulfurizing agents, technologies that simplify the structure of fuel processors, and technologies that operate the catalyst optimally, Tokyo Gas continues to contribute to wider adoption of its ENE-FARM system.

“So what is ENE-FARM? ENE-FARM is a coined word for energy and farm. It is a residential fuel cell micro-CHP system that provides the home with electricity, hot water and heat with high energy efficiency,” Ito explained.

“It enables power generation at home and covers 70% of power demand of a typical household.”

In an effort to help realise a low-carbon society, Tokyo Gas is promoting wider adoption of its ENE-FARM system.

Important elements to achieve such expansion are lower costs and a reduction in the size of the system, and it is therefore necessary to examine all components individually.

“Ten years have passed since the product launch of ENE-FARM and in November 2019, total unit sales in Japan reached 300,000, with 4,145 ENE-FARM units installed in the Tokyo 2020 Olympic Athletes Village condominiums,” Ito highlighted.

“For further expansion of market, reduction of size and cost has been required. Tokyo Gas has developed and launched the world’s smallest residential fuel cell ‘ENE-FARM mini’ in October 2019.”

“Depending on energy demand, customers can choose from three different ENE-FARM models. All three models can continue power generation at time of blackout.”

Other speakers in the panel included Alexander Dauensteiner, Product Line Owner Fuel Cells at Viessmann Deutschland, who discussed the role of hydrogen and fuel cells in the building sector, and Wayne-Daniel Kern, Commercial Director SOFC Project at Robert Bosch, who talked about stationary fuel cells.
