John Hatton: speaking at the Energy Storage World Forum.
By Mike Stone
Is hydrogen back in serious contention as a storage technology? A look at recent developments might indicate yes. Amazon, for example, has committed to spend USD$600m to buy up to 23% of fuel-cell maker Plug Power’s stock.
The online retailer will use the fuel cells it buys to help power forklift trucks in its warehouses. Plug Power said Amazon will be spending around USD$70m this year.
This spend will also cover stationary back-up power and hydrogen refueling infrastructure. Aiding lifting gear is an area where hydrogen has a well-defined niche, and its use is far from contentious.
But a more audacious recent proposal is one by a consortium comprising Carnegie Energy and Samsung EDI, among others, to build a 100MW hydrogen storage battery in South Australia.
According to Carnegie’s CEO, the company has already delivered 25-plus grid-scale storage systems in Australia. Read more →

GenCell, an Israeli fuel-cell maker, yesterday trumpeted a major win as part of an under-the-radar strategy to get utilities relying more on hydrogen.
The company said San Diego Gas & Electric (SDG&E), the Californian utility, would be installing GenCell G5rx fuel cells for substation backup power.
Bloomberg reported the deal would cover an initial three substations, with 27 more to follow within three years. SDG&E is keen to use fuel cells as a way of extending the backup power capacity at substations.
Backup power is a technical requirement at all utility substations. It is used to keep high-voltage circuit breakers open whenever there is a loss of power on the grid.
Most substations are equipped with lead-acid battery arrays that can supply backup power for up to eight hours. Beyond this, the utility usually has to switch to an alternative power source, such as a diesel genset. Read more →

What companies would you put your money in if you were a clean-tech angel investor looking to back an energy storage start-up? With plenty of young businesses out there crying for cash, it is not like you would be stuck for choice.
But, as Energy Storage Report found out last week at the KICInnoEnergyBusiness Booster in Barcelona, selecting a winner is not that easy… because there are so many good ideas to choose from.
The Business Booster was a two-day event where start-ups from a range of energy-related fields set out to woo an audience including nine angel investors and three venture capital firms. Five electricity storage hopefuls took the stage during the event.
Enerstone, of France, opened the storage track with a pitch for an ingenious battery management system that extends lifetimes and cycle rates by adjusting the draw on each cell to lessen the impact of weaker cells. Read more →

Areva is poised to announce its first major energy storage deal in Germany, according to Rémi Coulon, chief commercial officer at the company’s Renewables division. “We are about to announce our first client in Germany after having clients in France,” he told Energy Storage Report. “Germany is of course a key market for storage, it is where we see the most need. We are fine-tuning the press release.” Read more →

A hidden challenge for renewable energy, in terms of carbon reductions at least, is making sure your cure is not more damaging than your disease. Many types of renewable power plants, for example, contain large amounts of concrete and cement, the production of which involves significant greenhouse gas emissions.
The emissions involved in construction, from concrete or other sources, seem rarely to be included in calculations of the environmental benefit arising from renewable energy. Yet it is not inconceivable that a wasteful enough construction process might produce more carbon emissions than a project could save over its operating lifespan. Read more →
