Vodafone has installed a zero-emission ammonia-based off-grid power system at one of its mobile sites in Romania to test the potential of the technology. The GenCell Fox system is a low-temperature alkaline fuel cell which generates power from liquid ammonia with only water, nitrogen and heat as its by-products. Liquid ammonia is less flammable than gasoline, propane, hydrogen or natural gas and, as one might expect, emits a strong odor that makes leaks more easily detectable. Simtel, a Romanian photovoltaics company, is also involved in the project.

Also tooting its sustainability trumpet is Ericsson, which has introduced a new triple-band, tri-sector radio that it claims "can do the job of nine radios," cutting energy consumption by 40% compared to triple-band single-sector radios. The new radio combines 900, 800 and 700MHz frequency bands into one 2G-to-5G-capable radio. The 40% energy reduction, says Ericsson, can translate to annual savings per site that are equivalent to charging an electric car 40 times.

BT and Warner Bros. Discovery have closed their TV sports deal, with BT Sport and Eurosport UK assets now transferred into a new joint venture. For now, BT Sport and Eurosport UK retain their separate brands; in time they will be brought together under a single umbrella. BT received a £93 million (US$107 million) payment from Warner Bros. Discovery as part of the deal, but could earn up to £540 million ($624 million) in future, depending on certain conditions being met.
