Energy self-sufficiency, a dream for a number of homeowners, is now gradually becoming a reality. As isolated projects have already demonstrated, it is perfectly feasible to forgo a conventional grid connection and have a property’s entire energy needs met by renewables alone. The technology that makes this possible is on the tipping point of serial production following years of development, a move that could also bring the price down to a more acceptable level in the not too distant future.

Supplying zero-carbon energy to entire districts

An increasing number of building projects are now incorporating an energy supply based on hydrogen and fuel cells. Given the targets set out in the Paris climate agreement, the current thinking is clearly to avoid designing new housing developments that are dependent on fossil fuels and instead switch entirely to renewables. Due to the high expense that is sometimes associated with innovative energy technology, it makes sense to maximize the number of users. Residential neighborhoods in particular, which may run from several dozen homes to a hundred properties, are one way of making this alternative approach worthwhile.

Are fuel cell appliances fed by natural gas fit for the future?

Fuel cell heating appliances have now been on the market for several years. The choice, however, is limited and the prices are high, which explains the slow growth in the number of installations. Yet, perhaps there are other reasons why this section of the market has yet to pick up. For although there is currently a great deal of funding available for initiatives that encourage a switch to energy-efficient heating appliances, particularly when upgrading from an outdated oil-fired system, fuel cell heating units – just like condensing boilers – have the drawback of burning natural gas, thus making them a source of carbon dioxide emissions.

Future accounting calculates sustainability

Christian Hiß
Hiss: “They key is to change the way we account for profits and losses.”

Money makes the world go round. Companies seek to maximize profits, countries their GDPs. In both cases, we are dealing with figures in dollars, euros or some other currency. But what about values or services without a price tag? Such as employee health. The advice and expertise of colleagues freshly retired. What is the long-term cost of cutting down a forest? How expensive is sustainable (or industrial) farming? So far, most accounting revolves solely around financial issues.

Interview with NOW chief executive Kurt-Christoph von Knobelsdorff

As of May 15, 2020, the National Organization for Hydrogen and Fuel Cell Technology (NOW) has a new chief executive. Formerly Klaus Bonhoff, who has moved to the German transportation ministry, his successor is Kurt-Christoph von Knobelsdorff. Now is the time to take stock and ask what the future holds.
